Two Years After the School Phone Ban in Australia: What Changes Have We Seen? | Children

When the Australian Christian College, a secondary school situated in Melbourne’s Casey suburb, enforced a mobile phone ban, it was driven by numerous factors. There was an escalation in peer conflicts online, students had difficulty maintaining focus, and teachers noticed students engaging in “code-switching on notifications.”

Caleb Peterson, the school’s principal, stated, “When a phone is within arm’s reach, a student’s attention is only half in the room. We aimed to reclaim their full attention.”

Traditionally, cell phone bans in educational institutions necessitate that devices be stored in bags or lockers during class hours, with confiscation upon discovery to be retained in the school office until the day’s end. This month signifies the two-year mark since the introduction of phone bans across many Australian states. Victoria notably pioneered this move by prohibiting mobile phone usage in public primary and secondary schools back in 2020. By the close of the fourth term in 2023, Western Australia, Tasmania, New South Wales, and South Australia implemented similar measures, with Queensland limiting mobile phone use starting early 2024.

The announcement regarding the ban received endorsement from both parents and politicians, many of whom contended that: restricting access to phones enhances focus and minimizes distractions, though some experts expressed doubts concerning its efficacy. Two years later, what has truly transpired within Australia’s phone-free schools?

“The effects have been evident,” Peterson remarked. “Post-ban, we’ve enhanced class beginnings, diminished disruptions, and improved class dynamics. Conflicts related to devices have reduced, and recess and lunch have transformed. We now see games, conversations, and positive interactions among students and staff. That’s the atmosphere young people seek.”


A year following the implementation of the ban, a survey involving nearly 1,000 public school principals, conducted by the NSW Department of Education’s Center for Education Statistics and Evaluation, revealed that 95 percent still advocated for the ban. Furthermore, 81% believed the ban enhanced student learning, 86% indicated improved student interactions, and 87% perceived fewer classroom distractions.

Research from South Australia—released earlier this March—indicated that 70% of educators noticed increased focus and engagement during learning periods, while 64% noted “a reduction in the rate of serious incidents” attributable to device usage.

Lucaya, a graduate from a western Sydney high school in 2024, views the ban as an “overreaction.” Having experienced both unrestricted cell phone use and the ban during her final year, she reports that students still find covert ways to use their devices.

“Teenagers regard cell phones as vital,” she asserts. “It provides them with a sense of safety and security. Denying them something that holds such significance will only exacerbate stress and anxiety, complicating matters for teachers and administrators.” [and] assisting staff in coping.”

Nevertheless, anecdotal evidence from dialogues with students and staff across various public and private institutions suggests a general consensus that the ban has yielded positive outcomes. An anonymous high school teacher noted that simply having mobile phones present in classrooms can prove distracting, even if not actively used. “They simply offer opportunities,” she commented. “You can distinctly notice the difference in their absence.”

Many students believe the ban has created a more equitable learning environment. Amy, a Year 11 student at a public high school in Sydney’s west, remarked that eliminating mobile phones in classrooms has curtailed misbehavior while also fostering social connections for those who spend excess time online.

“Students [feel more at ease] “It fosters a safe environment where we don’t have to stress about people sharing pictures of us,” she stated.

Mariam, a Year 11 student at a public high school in Sydney’s south, felt that the phone ban was “unjust” and claimed that teachers occasionally used it to exert authority, but admitted it positively influenced learning outcomes. Aisha, a Year 11 student from a private Islamic school in Sydney’s west, noted that the phone ban has helped her “maintain attention longer and perform better academically.”

Dr. Tony Mordini, principal of Melbourne High School, a public selective institution, has observed this heightened attention firsthand. His school adopted a no-phone policy in January 2020, following guidelines from the Victorian Department of Education.

“From a professional perspective, this ban has clearly had a beneficial impact,” he stated. “Students exhibit increased focus during lessons and are less sidetracked by online distractions. Furthermore, the absence of phones has significantly curtailed opportunities for cyberbullying and harassment in classrooms.”

However, Mordini acknowledges that the ban also curtails certain student opportunities.

“It’s crucial to recognize what we’ve surrendered,” he remarks. “Mobile phones can serve as powerful educational tools, capable of storing extensive content, assisting with research, capturing photographs, creating videos, and hosting valuable applications. Lacking a mobile phone necessitates reliance on the traditional resources and devices provided by the school.”

Professor Neil Selwyn from Monash University’s School of Education, Culture, and Society, stated, “We’ve been informed that banning phones will curb cyberbullying, enhance concentration in class, and reduce the need for teachers to discipline for phone misuse.” Some politicians promised to boost student learning and mental health, but a significant impetus behind these bans was their popularity.

He suggested that schools might serve as a stand-in for wider concerns about children and their device usage, but questions whether schools serve as the optimal solution.

“Young people spend a significant amount of time outside school, thus parents and families must engage in discussions on regulating their children’s device usage at home,” he emphasizes. “Regrettably, this isn’t a priority for most policymakers, so enacting phone bans in schools feels like an easy way to address the broader issue of excessive digital device use.”

Mr. Selwyn indicated that Australia’s phone ban was not implemented “with the intent of thoroughly investigating its effectiveness” and termed specific research into this field as “not conclusive or particularly rigorous.”

He further asserted that recent government data from New South Wales and South Australia is “not particularly illuminating.”

“The critical concern remains how these bans will affect us over time,” he noted. “Claims suggesting these bans suddenly result in dramatic improvements may sound politically appealing, but the tangible impact of these bans necessitates more comprehensive and ongoing investigation.

“We must go beyond merely asking principals if they believe student learning has enhanced. We need to enter classrooms and engage students and teachers about their varied experiences with the ban, and the potential benefits they foresee moving forward.”

He referenced a recent UK study of 30 schools and over 1,200 students which concluded that “students in schools devoid of smartphones showed no notable differences in mental health, sleep, academic performance in English or mathematics, or even disruptive behavior in class.”

“Phone bans are not a silver bullet, but they serve as an important tool,” Peterson comments. Photo: Dan Peled/AAP

“While some studies imply a connection between phone bans and improved academic performance, they are not deemed to provide reliable evidence of direct causation,” he states. “It would be imprudent to assume a phone ban would singularly and significantly rectify these issues.”

Peterson takes care not to “exaggerate” the ban’s implications but asserts that it aims to “foster conditions conducive to successful learning and friendships.” Despite exempting medical management, disability support, or assistive translation applications, he contends that academic flow is enhanced, conflict is reduced, and social unity is improved. His school’s “health metrics” indicate “lessened psychological distress.”

“Phone bans are not a panacea,” he notes. “However, they are a valuable resource, particularly when paired with digital citizenship, mental health advocacy, and positive playground initiatives.”

Peterson conveyed that numerous students suggested the ban offers them a “reprieve.”

“Phone bans have now simply become the norm, with real and modest benefits that are genuinely worthwhile.”

Coral Reefs Face a Critical Threshold Due to Climate Change

Coral reefs are critically threatened by climate change

WaterFrame/Alamy

The recent surge in ocean temperatures has led to extensive bleaching and mortality of warm-water corals globally, marking the onset of the first climate tipping point in an ecosystem on Earth, as stated by scientists.

The deterioration of one of the planet’s most biodiverse and vulnerable ecosystems presents ‘risks to human health and safety’ for which governments are inadequately prepared, cautions Melanie McField, who oversees Florida’s “Healthy Reefs for Healthy People” conservation initiative under the Smithsonian Institution.

Warm-water coral reefs account for one-third of all known marine biodiversity and offer food, coastal protection, and livelihoods for approximately one billion individuals worldwide. Additionally, coral reefs contribute $9.9 trillion annually in goods and services globally.

However, corals are particularly vulnerable to fluctuations in water temperature. Record-breaking global temperatures in 2023 have elevated ocean heat levels to unprecedented highs, resulting in significant bleaching events impacting over 80 percent of the world’s corals. Bleaching occurs when corals react to elevated water temperatures by expelling the algae residing within their tissues, leading them to bleach white. This process can make corals more prone to disease, and prolonged bleaching can deplete their primary food supply, ultimately leading to their death.

The most recent bleaching event represented “an order of magnitude” beyond what scientists had previously witnessed, according to McField. “We are at a tipping point,” she acknowledged. This is generally understood as a crucial threshold that, if crossed, can trigger dramatic and potentially irreversible changes in the climate system.

McField contributed to the chapter on corals in the Global Tipping Point Report 2025, which is now available for purchase. This report, the first update since 2023, was compiled by 160 scientists globally and coordinated by the University of Exeter and campaign organization WWF. It warns that warm-water corals are the initial component of the Earth system to reach a tipping point and are currently facing an “unprecedented crisis.”

Leading experts estimate that the thermal threshold for warm-water corals will be reached at a 1.2 degrees Celsius increase in global atmospheric temperatures above pre-industrial levels, with an upper limit of 1.5 degrees Celsius. By 2024, the world’s average temperature is expected to surpass this 1.5 degrees Celsius threshold for the first time in human history, exceeding the limits within which coral reefs can survive, noted Tim Renton, who spearheaded the report at the University of Exeter.

“We assessed the world at a temperature of 1.5 degrees Celsius and confirmed the results,” he stated during a press conference ahead of the report’s release. “Most coral reefs are at risk of large-scale mortality or bleaching and are transitioning into a different state dominated by seaweed and algae.”

The most promising chance to save the world’s warm-water corals from near-total extinction lies in rapidly reducing global average temperatures to 1.2 degrees Celsius below pre-industrial levels, Renton asserts. However, whether this ambitious goal, which exceeds even the targets set for 1.5°C, is attainable remains uncertain.

Terry Hughes, a researcher from Australia’s James Cook University, emphasizes that “few unbleached coral reefs remain worldwide”. Nonetheless, there is still potential for improvement. “If global greenhouse gas emissions are swiftly curtailed, we can influence the future of coral reefs over the next few decades,” he states.

Although the timing of climate tipping points is often uncertain, researchers caution that significant declines in the Amazon rainforest, melting of polar ice sheets, and collapse of the crucial AMOC current may all occur at warming levels below 2°C.

Moreover, humans can also instigate “positive tipping points” to mitigate these risks, Renton highlighted, pointing to the rapid advancements in renewable energy and the increased adoption of electric vehicles in the past decade. Fast-tracking cleaner technologies could significantly reduce emissions and help keep global warming well below 2°C, the report suggests.

Renton stated that immediate action is crucial from world leaders during the upcoming COP30 summit in Brazil to expedite emissions reductions across the global economy and minimize the duration for which global temperatures exceed 1.5 degrees Celsius. “We are swiftly nearing tipping points in various Earth systems that could have catastrophic impacts on humanity and nature, fundamentally altering the planet. This necessitates immediate and unprecedented action from COP30 leaders and policymakers worldwide,” he urged.

Say Goodbye to Spotify: A DIY Movement for Artists and Fans to Ditch Music Apps

TThis past month, independent musicians in San Francisco convened for a series of discussions titled “Death to Spotify,” where attendees delved into “the implications of decentralizing music discovery, production, and listening from a capitalist framework.”

Hosted at Bathers Library, the event featured speakers from indie radio station KEXP, record labels Cherub Dream Records and Dandy Boy Records, along with DJ collectives No Bias and Amor Digital. What began as a modest gathering quickly sold out, gaining international interest. Organizers were approached by individuals as far away as Barcelona and Bengaluru eager to replicate the event.

These discussions occur as the global backlash against Spotify gains traction. In January, music journalist Liz Perry released *Mood Machine*, a critical examination arguing that streaming services have decimated the industry, turning listeners into “passive, unstimulated consumers.” Perry asserts that Spotify’s business model pays artists meagerly, particularly if they consent to be “playlisted” in discovery mode, which delivers a bland, ambient soundtrack that blends into the background.

While artists have long voiced concerns over inadequate compensation, this past summer, criticism turned personal, specifically targeting Spotify’s billionaire co-founder Daniel Ek’s backing of Hellsing, a German company developing military technology AI. Prominent acts like Massive Attack, King Gizzard & the Lizard Wizard, Deerhoof, and Hotline TNT have pulled their songs from the platform in protest, though Spotify stresses that “Spotify and Hellsing are entirely separate entities.”

In Oakland, Stefani Dukic read *Mood Machine*, learned about the boycott, and felt inspired.

While not a musician, Dukic, who investigates city police complaints, describes her fascination with sound alongside her friend Manasa Karthikeyan, who works in an art gallery. They decided to foster a similar dialogue. “Spotify plays a vital role in our music interaction,” Dukic explains. “We thought it would be enriching to investigate our relationship with streaming, the significance of deleting a file, and the process involved.” Thus, Death to Spotify was conceived.

In essence, the aim was to “end algorithmic listening, cease royalty exploitation, and discontinue AI-generated music.”

Karthikeyan believes the onus of quitting Spotify falls on both listeners and musicians. “One must acknowledge that not everything is instantly available,” she states. “It prompts deeper consideration of what you support.”

Yet, will musicians and fans truly commit to a long-term boycott of the app?

Numerous prominent artists have previously pulled their catalogs from Spotify amid much fanfare, only to quietly return. Taylor Swift, one of the platform’s biggest stars, returned in 2017 after a three-year boycott over unfair payment practices. Thom Yorke, the frontman of Radiohead, removed some solo projects in 2013 for similar reasons, labeling Spotify as “the last desperate fart of a dying corpse,” yet he later reinstated them.

In 2022, Neil Young and Joni Mitchell left the platform due to an exclusive deal with anti-vaccine podcast host Joe Rogan. Having both contracted polio in their childhood during the 1950s, they have also reinstated their catalogs on Spotify.

Eric Drott, a music professor at the University of Texas at Austin, suggests this latest wave of boycotts feels distinct. “These artists are not mainstream. Many have realized for years that streaming isn’t lucrative, but they still sought recognition. With the sheer volume of available music, people are questioning its overall value.”

Will Anderson of Hotline TNT asserted there is “0%” chance his band will return. “There’s no rationale for genuine music enthusiasts to be there,” he claims. “Spotify’s primary objective is to encourage you to stop pondering what’s being played.” When the band sold their new album, “Raspberry Moon,” directly via Bandcamp and a 24-hour Twitch stream, it sold hundreds of copies and generated substantial revenue.

Pop-rock artist Caroline Rose and others are also experimenting with alternative distribution methods. Her album *Year of the Slug*, influenced by Cindy Lee’s “Diamond Jubilee,” was exclusively released on vinyl and Bandcamp, initially available only on YouTube and the file-sharing platform Mega. “It’s disheartening to pour your heart and soul into something only to give it away online for free,” Rose articulates.

Rose is a member of the Union of Musicians and Allied Workers (UMAW), an advocacy organization established to protect music professionals since the onset of the COVID-19 pandemic. Joey DeFrancesco, a member of the punk band Downtown Boys and a UMAW co-founder, stated the group “clearly advocates for artists as agents, holding corporations accountable and facilitating necessary dialogue,” including efforts to remove music from Spotify. He also noted the “limitations” inherent in individual boycotts.

“Our goal in the labor movement and within UMAW is to act collectively,” he emphasized. Notable examples include UMAW’s successful campaign—in partnership with the Palestine for Palestine coalition—to persuade the South by Southwest music festival to cut ties with U.S. military and arms manufacturers as sponsors for its 2025 event, as well as the introduction of the Living Wage for Musicians Act (a bill aimed at regulating payments to artists on Spotify) championed by Congresswoman Rashida Tlaib.

The organizers of Death to Spotify assert that their intent isn’t to dismantle the app but rather to prompt users to critically reflect on their music consumption habits. “We want to encourage a more thoughtful engagement with how we listen to music,” Karthikeyan explains. “Sticking to algorithmically generated comfort zones only serves to diminish the richness of our culture.”

Looking to Upgrade Your Laptop?

Is it really time for a new laptop?

If you’re contemplating an upgrade, a new laptop you’re in good company. Many individuals consider replacing their device when it starts to feel sluggish or antiquated. However, before you invest in the latest technology, it’s crucial to ask: Do you truly need a new laptop?

For the majority of users, the answer is: no. The reality is that the requirements for laptop performance haven’t evolved significantly even as technology progresses. Whether you’re browsing, participating in video conferences, or working on spreadsheets, your current laptop likely meets all your needs.

Reasons not to upgrade

If your laptop is still adequate for your daily tasks, an upgrade might be unnecessary. Here’s why:

  1. Most applications don’t need cutting-edge specifications.
    Upgrading from an Intel Core i3 to an Ultra Core 5 won’t necessarily speed up report generation. Productivity is often influenced more by effective workflows than by raw CPU speed.
  2. New ports are adaptable.
    Even without USB-C or Wi-Fi 7, adapters and dongles make it simple to connect to modern devices.
  3. It’s both financially and environmentally responsible.
    A new laptop could set you back between $1,000 and $10,000, and its production utilizes rare minerals and significant energy. Repairing or upgrading your existing device is better for your finances and the environment.

When is buying a new laptop justified?

There are valid reasons for purchasing a new laptop in 2025.

  • Severe physical damage or hardware failure (e.g., a malfunctioning motherboard or a battery that can’t be replaced)
  • Display or keyboard issues that hinder daily usage
  • Incompatibility with essential new software vital for work or study

If your current device meets any of these criteria, it might be time for a replacement. Otherwise, with a few tweaks, you can restore your laptop to like-new condition.

Enhancing laptop performance without a new purchase

1. Optimize startup programs

Excessive startup applications can degrade performance.

  • On Windows, open Task Manager → Startup and disable any unnecessary apps.
  • On macOS, navigate to System Settings → Users and Groups → Login Items and remove what you don’t need.

2. Uninstall unused browser extensions

Extensions can consume resources and slow down your browsing experience.
For Chrome, enter: chrome://extensions in the address bar and remove any outdated extensions.

3. Free up storage

Utilize a free disk analysis tool such as:

  • WinDirStat (Windows)
  • Disk Inventory X (Mac)

Delete large files, outdated downloads, and applications you no longer use. This can free up valuable space and help you avoid costly storage upgrades.

4. Consider hardware upgrades

Small upgrades can significantly enhance your system’s performance.

  • Add RAM (8GB is the minimum, but 16GB is recommended)
  • Switch from HDD to SSD for improved speed
  • Replace your battery if it drains quickly

5. Reinstall the operating system

A clean OS installation can eliminate years of accumulated digital clutter.
Be sure to back up your files first, then download and reinstall the operating system from the official site. You may be surprised by the enhanced performance.

Don’t overlook physical cleaning

One of the best parts of getting a new laptop is how fresh and tidy it is.
To refresh your current device:

  1. Shut down and disconnect.
  2. Use a microfiber cloth to wipe down the screen and surfaces.
  3. Turn the keyboard upside down and gently vacuum to remove any dust or debris.

A clean laptop not only looks appealing but also enhances airflow and minimizes overheating.

Final thoughts: Make wise upgrade decisions

Before you rush to purchase a new laptop, consider enhancing the performance of your current device.
Through simple maintenance, a handful of upgrades, and good cleaning practices, you can extend the lifespan of your laptop by several years— saving money and benefiting the planet.

If you do decide to buy a new one, research thoroughly and focus on what truly matters: performance, reliability, and user experience— not just impressive specifications.

Is It Time for a New Laptop? When to Upgrade and When to Wait | Technology

SI’m considering getting a new laptop. It’s a common sentiment; most people feel this way at some point, typically after the initial excitement of a new device wears off. As technology progresses, newer models beckon, making it easy to forget the device you currently own.

I’m not here to judge your choice, but as someone with a background in technology, I can offer insights that might help you resist the temptation to upgrade.

Let’s begin with the essentials. The primary reason most people don’t acquire a new laptop is simply that they don’t need one. We live in a world where technology evolves rapidly, but the tasks we perform on our laptops have changed at a much slower rate. For most of us, 99% of our time is spent on a few key applications: web browsers, video conferencing tools, word processors, and presentation or spreadsheet software.

If you’re seeking a new laptop because your current one has a subpar screen or a frustrating keyboard, you may indeed have a valid reason. However, if it’s all about that faster processor or more storage, SSD, take a breather. Do you truly believe that transitioning to a Core Ultra 5 processor from an older i3 will drastically improve your report writing speed? Before blaming your tech, consider where your productivity stands.

Additionally, having an outdated connector isn’t a strong argument either. While your laptop may not possess the latest USB ports or Wi-Fi capabilities, the beauty of modern standards lies in their impressive backward and forward compatibility. There’s no need for a new laptop just to connect with your state-of-the-art Wi-Fi 7 router—my Wi-Fi 5 card still performs fine (even though Windows updates might take longer). With the right cable or adapter, you can use any USB device dating back to 1996.


Save Money and the Environment

Also, consider that staying with your current laptop could save you money. Spending upwards of $10,000 on a high-spec device is significant, and the notion of a long-term investment might make it feel justified. However, that amount might be better allocated elsewhere.

If you’re facing issues with your laptop and contemplating a replacement, repairs could offer a more economical solution. Unfortunately, this isn’t always feasible due to the trend toward factory-sealed devices and soldered components. Still, sometimes, a damaged laptop can be restored for a fraction of the replacement cost.

Another point against retiring your old laptop is that producing a new one requires environmentally damaging materials, and disposing of an old laptop can be more harmful to the environment.

Finally, after unboxing your sleek new laptop, you’ll likely spend days or weeks reinstalling various software and drivers, tweaking settings until it functions just like your old laptop did.


How to Maximize Your Existing Laptop


Upgrading your hardware can give your laptop a new lease on life. Photo: baona/Getty Images/iStockphoto

If you decide to keep your laptop, there are steps to improve its performance. If you’re annoyed by constant pop-ups or sluggishness, consider reviewing your startup items and disabling those you don’t need. Windows can function smoothly without third-party apps launching at startup. Likewise for Mac users, check your login items and eliminate the unnecessary.

The same applies to browser extensions, which can accumulate, leading to a cluttered browsing experience. Each extension uses resources and can impact performance. If you use Chrome, enter chrome://extensions in the address bar to remove unmaintained extensions. For Microsoft Edge, use edge://extensions; for Safari, go to [設定] and select [拡張機能].

While you’re at it, conduct a thorough clean-up of your storage as well. Numerous effective free tools can analyze your hard drive and show you what’s consuming space. My favorites include WinDirStat for Windows and Disk Inventory X for Mac. You might be surprised by how much space is occupied by old downloads and unnecessary applications. Deleting them might not speed up your computer, but if storage is a concern, it could help stave off the urge to upgrade.

Alternatively, breathing new life into your laptop could be a matter of hardware upgrades. While this isn’t always feasible, it’s worthwhile to see if you can increase your memory, enhance storage, or replace the battery. Notably, boosting your RAM can dramatically enhance your overall experience, as modern operating systems and applications are designed with a baseline of at least 8GB in mind and often prefer 16GB or more to operate smoothly.

There’s also the comprehensive option of a complete system wipe and reinstallation. Thanks to modern technology, you don’t need to juggle floppy disks anymore; you can easily download and reinstall operating system files from the Internet. This process can refresh your laptop, but remember, it will revert your computer to the original, uncustomized state like a brand-new laptop. Before doing this, ensure you back up all your personal files, as reinstallers might suggest preserving documents and settings, but any loss will be your responsibility.

While we’re discussing this, don’t overlook the benefits of physical cleanliness. Part of the excitement of a new laptop often comes from a pristine screen and clean, responsive keys. I recommend shutting down your laptop, grabbing a non-abrasive cloth (a microfiber one is ideal), and giving it a thorough wipe down. Following that, turn it upside down and use a handheld vacuum to clean the keyboard, making sure to scrub the keys and remove any dust or small debris.


You Might Need a New One After All: Signs to Upgrade Your Laptop


In some cases, purchasing a new laptop may be unavoidable. Photo: Westend61/Getty Images

Despite these points, there are situations where investing in a new laptop is justified. As noted earlier, repairs and upgrades might not be viable options. If your screen is cracked, the only recourse may be to consult with a computer repair shop.

Another frustrating scenario arises when the hardware functions properly but is just too old to accommodate the latest operating systems and security updates. For the first time in about a decade, this issue is emerging with Apple systems, impacting millions of PCs as Microsoft will end support for Windows 10 on October 14th. Systems meeting Windows 11’s requirements can upgrade for free, leaving older models unsupported.

If your computer falls into this unfortunate category and you’re not in a position to switch to a different operating system, then acquiring a new laptop becomes crucial. Although continuing to use unsupported software is possible, we ethically cannot recommend it, as it exposes you to security vulnerabilities.

This doesn’t mean you have to dispose of your existing laptop. Almost any device can support the free Linux operating system, allowing you to use it for basic tasks like web browsing, document editing with LibreOffice, or video calls.

Alternatively, Google’s ChromeOS Flex platform presents a free version of the Chromebook OS that can be installed on various laptops. Whether you keep it for yourself or gift it, you’re contributing to its lifespan and helping mitigate the environmental impact associated with its disposal.

Lastly, it’s important to consider the social aspect of this situation. Portable computers are meant to be seen. Using an older laptop at your local café might communicate a message, but it doesn’t necessarily carry a negative connotation; it indicates loyalty and practicality, showcasing your resistance against consumerism.

Emergency Alert Issued as Heat Wave Endangers Two Southwestern Counties

LAS VEGAS — As spring temperatures began to climb in Phoenix, Dr. Jeffrey Johnston prepared for a grim summer trend featuring numerous fatalities.

In the past decade, Johnston, the chief medical examiner for Maricopa County, Arizona, has witnessed an alarming rise in deaths attributed to extreme heat. The heat-related fatalities in the county surged from several dozen in 2014 to 645 in 2023.

“The spike was so severe and prolonged that we approached it as a mass casualty incident,” he commented, referring to the recent summer.

However, Maricopa County—home to the most populated area in the desert southwest—has made significant investments in heat preparedness and mitigation strategies. Cooling centers in Phoenix are now operational every day of the week. The county has scaled up its heat safety communications efforts and appointed a full-time heat mitigation coordinator.

Consequently, there were fewer heat-related deaths last year compared to the previous year, despite experiencing record temperatures for the first time in a decade. With summer concluded, officials are reviewing the year’s achievements, and initial data indicates that the trend of decline is continuing: Maricopa County has reported 185 heat-related fatalities so far, significantly lower than the 284 reported at the same time last year.

In contrast, a troubling situation is arising in Clark County, Nevada’s second most populous area, which includes Las Vegas. The fatalities from heatstroke here have more than tripled within three years, reaching a record high of 513 in 2024. While the current year’s death toll is still not finalized, it is expected that the number of heat-related deaths will be in the hundreds.

Ariel Choinard, a scientist at the Desert Research Institute in Las Vegas, noted that last summer’s extreme heat served as a major wake-up call.

“Seeing a 120-degree temperature in Las Vegas made people realize, ‘Oh my gosh, this is really serious,'” she said.

Choinard has been pivotal in local initiatives addressing heat-related fatalities in Clark County and is tracking advancements in Maricopa County. She recognizes there is still work to be done.

“They began tackling the heat issue earlier than we did here, so they have made more progress in several respects,” she remarked.

Heat causes more fatalities in the United States each year than other weather-related disasters such as hurricanes, floods, and tornadoes, as reported by the National Weather Service. As climate change exacerbates the frequency and severity of heat waves, these two counties in one of the fastest-warming regions of the U.S. exemplify the urgent measures needed to preserve lives in light of this escalating threat and the severe consequences of inaction.

“All of these deaths are preventable.”

Heat disproportionately affects vulnerable populations. Individuals lacking access to air conditioning, including those experiencing homelessness or residing in low-income areas or mobile homes, face heightened risks. Outdoor workers, people with pre-existing conditions, and the elderly are also at increased danger.

In Maricopa County last year, 49% of heat-related deaths were linked to homelessness, while 57% were due to substance use. Therefore, strategies aimed at preventing fatalities from extreme heat must prioritize these vulnerable groups.

Maricopa County sought to address this by expanding its network of cooling centers and hydration stations in 2023, especially after experiencing 31 consecutive days of record-breaking temperatures of 110 degrees or higher that led to a rapid increase in heat-related deaths.

Using Profanity in Google Searches Might Make AI Stop Responding – Is It Worth It?

Using explicit language in your Google searches can help reduce the frequency of unwanted AI-generated summaries. Some applications also provide options to disable artificial intelligence features.

You might consider not utilizing ChatGPT, steering clear of AI-integrated software, or avoiding interactions with chatbots altogether. You can disregard Donald Trump’s deepfake posts, and find alternatives to Tilly the AI actor.

As AI becomes more widespread, so do concerns regarding its associated risks and the resistance to its omnipresence.

Dr. Kobi Raines, a specialist in AI management and governance, emphasizes that healthcare professionals often feel compelled to utilize AI.

She mentioned that she preferred not to use AI transcription software for her child’s appointment, but was informed that the specialist required it due to time constraints and suggested she seek services elsewhere if she disagreed.

“There is individual resistance, but there are also institutional barriers. The industry is advocating for the use of these tools in ways that may not be sensible,” she states.


Where is the AI?

AI is deeply embedded in digital frameworks.

It’s integrated into tools like ChatGPT, Google’s AI repository, and Grok, the controversial chatbot developed by Elon Musk. It informs smartphones, social media platforms, and navigation systems.

Additionally, it’s now part of customer service, finance, and online dating, impacting how resumes, job applications, rental requests, and lawsuits are evaluated.

AI is expected to further integrate into the healthcare sector, easing administrative workloads for physicians and aiding in disease diagnoses.

A University of Melbourne Global Studies report released in April noted that half of Australians engage with AI regularly or semi-regularly, yet only 36% express trust in it.

Professor Paul Salmon, deputy director of the Center for Human Factors and Socio-Technical Systems at the University of the Sunshine Coast, highlights that avoiding AI is becoming increasingly challenging.

“In professional environments, there’s often pressure to adopt it,” he shares.

“You either feel excluded or are informed you will be.”


Should we avoid using AI?

Concerns include privacy violations, biases, misinformation, fraudulent use, loss of human agency, and lack of transparency—just a few risks highlighted in MIT’s AI risk database.

It warns about AIs potentially pursuing objectives conflicting with human goals and values, which could lead to hazardous capabilities.

Greg Sadler, CEO of Good Ancestors charity and co-coordinator of Australians for AI Safety, frequently references the database and advises caution, stating, “Never use AI if you don’t trust its output or are apprehensive about it retaining information.”

Additionally, AI has a sizable energy footprint. Google’s emissions rose by over 51%, partly because of the energy demands of its data centers that facilitate AI operations.

The International Energy Agency predicts that electricity consumption by data centers could double from 2022 levels by 2026. Research indicates that by 2030, data centers may consume 4.5% of the world’s total energy production.


How can I avoid using AI?

AI Overview features a “Profanity Trigger.” If you inquire on Google, “What is AI?” its Gemini AI interface may provide a bland or sometimes inaccurate response, acting as an “answer engine” rather than a “search engine.”

However, posing the question, “What exactly is AI?” will yield more targeted search results along with relevant links.

There are a variety of browser extensions capable of blocking AI-related sites, images, and content.

To bypass certain chatbots, you can attempt to engage a human by repeating words like “urgent” and “emergency” or using the term “blancmange,” a popular dessert across Europe.

James Jin Kang, Senior Lecturer in Computer Science at RMIT University, Vietnam, remarked: living without it entails taking a break from much of modern life.

“Why not implement a kill switch?” he questions. The issue, he claims, is that AI is so deeply entrenched in our lives that “it’s no longer something you can easily switch off.”

“As AI continues to seep into every facet of our existence, it’s imperative to ask ourselves: Do we still have the freedom to refuse?”

“The real concern is not whether we can coexist with AI, but whether we possess the right to live without it before it becomes too late to break away.”


What does the future hold for AI?

Globally, including in Australia, governments are grappling with AI, its implications, potential, and governance challenges.

The federal government faces mounting pressure to clarify its regulatory approach as major tech firms seek access to journalism, literature, and other resources necessary for training their AI models.

The discussion includes insights from five experts on the future trajectory of AI.

Notably, three out of five experts believe AI does not present an existential threat.

Among those who express concerns, Aaron J. Snoswell of the Queensland University of Technology opines that the transformative nature of AI is not due to its potential intelligence but rather to “human decisions about how to construct and utilize these tools.”

Sarah Vivian Bentley of CSIRO concurs that the effectiveness of AI is dictated by its operators, while Simon Coghlan of the University of Melbourne argues that despite the worries and hype, evidence remains scant that superintelligent AI capable of global devastation will emerge anytime soon.

Conversely, Nyusha Shafiabadi of Australian Catholic University warns that although current systems possess limited capabilities, they are gradually acquiring features that could facilitate widespread exploitation and present existential risks.

Moreover, Saydari Mirjalili, an AI professor at Torrens University in Australia, expresses greater concern that humans might wield AI destructively—through militarization—rather than AI autonomously taking over.


Raines mentions she employs AI tools judiciously, utilizing them only where they add value.

“I understand the environmental impacts and have a passion for writing. With a PhD, I value the process of writing,” she shares.

“The key is to focus on what is evidence-based and meaningful. Avoid becoming ensnared in the hype or the apocalyptic narratives.

“We believe it’s complex and intelligent enough to accommodate both perspectives, implying these tools can yield both beneficial and detrimental outcomes.”

Tony Blair and Nick Clegg Host Dinner to Connect Tech Leaders with UK Ministers

Earlier this year, Tony Blair and Nick Clegg organized a private dinner where a group of technology entrepreneurs had the opportunity to meet influential ministers, as revealed by official documents.

As a long-time supporter of the tech industry, the former prime minister hosted this dinner at a high-end hotel in London, representing the Tony Blair Institute (TBI) political consultancy.

Together with former deputy prime minister Mr. Clegg, who was a senior executive at Meta at the time, they invited leaders from six tech firms, including Poppy Gustafsson, the government’s investment minister tasked with encouraging businesses to invest in the UK.

Mr. Blair is a passionate advocate for the transformative potential of technology in public services and has actively sought partnerships with industry leaders. His consultancy has produced several policy papers that advocate for placing artificial intelligence at the core of government initiatives.

However, some critics express concerns that Prime Minister Blair, known for his close ties to Keir Starmer’s administration, has been able to influence the agenda without adequate public oversight. There are also questions surrounding the reliance of Blair’s consultancy on significant contributions from Silicon Valley’s billionaire Larry Ellison, an acquaintance of Donald Trump and Elon Musk.

Mr. Ellison, who briefly claimed the title of the world’s richest person this year, has donated or committed over $300 million to Mr. Blair’s consultancy.

Documents obtained by the Guardian through freedom of information laws reveal that 12 attendees discussed the government’s evolving stand on artificial intelligence at a gathering deemed a “salon dinner.”

Do you have any information about this story? Email henry.dyer@theguardian.com or message (using your non-work phone) Signal or WhatsApp to +44 7721 857348. For the most secure communications, visit theguardian.com/tips.

The dinner took place at the luxurious Corinthia Hotel in late January and featured Ron Jaffe, managing director of Insight Partners, a US venture capital firm investing in tech companies.

Also present was Alex Kendall, CEO of Wave, focused on self-driving cars, along with Nigel Thune, head of Graphcore, a computer chip manufacturer, and Mark Warner, CEO of Faculty AI, who last year collaborated with TBI to produce a document on leveraging AI to enhance public services.

A representative for Mr. Clegg noted, “During his tenure at Meta, Nick Clegg frequently interacted with government ministers and other tech CEOs, which is standard for his role in policy and global affairs.”

According to a TBI spokesperson, “The event featured discussions with ministers about various issues among tech leaders. No companies were charged to attend.”

Companies that participated asserted they do not contribute to or employ TBI.

This dinner illustrates how Prime Minister Blair’s consultancy is advancing pro-technology policies. The rapidly growing TBI is active in 45 countries and employs over 900 staff members. Its most recent financial statement reported revenues of $145 million in 2022 from advisory services and donations, although many donors and clients remain undisclosed.

The consultancy faces criticism for potentially allowing donor interests to influence its policy positions, a claim it disputes. It has also been criticized for continuing financial ties with Saudi Arabia following the murder of journalist Jamal Khashoggi in 2018. Blair is anticipated to play a significant role in the reconstruction of Gaza following the war.

Weeks prior to the dinner, the government confidentially provided an outline of an AI action plan to TBI shortly before it was set to be publicly released. On January 9, Ferial Clark, then Minister of Science, Innovation and Technology (DSIT), made this request at the prompting of TBI’s Director of Science Policy, Jacob Mokander.

The following day, an aide to Mr. Clark reached out to Mr. Mokander stating, “It was a pleasure speaking with you. As a follow-up, here’s the top-secret action plan summary. Thank you for expanding the plan through your networks and supportive quotes on Monday.” Mr. Mokander replied, “Thanks for sharing the action plan (confidentiality).” Blair endorsed the action plan on January 13, which aims to bolster the UK’s role in AI development and deployment.

When asked why this document was shared with TBI so early, a DSIT spokesperson stated, “We cannot apologize for our regular engagement with stakeholders. It’s standard to share embargoed information with them ahead of publication.”

A spokesperson for TBI remarked, “It’s typical for governments to consult experts and engage various stakeholders when crafting policy. As indicated in the footnotes, the AI Opportunity Action Plan accurately references our published work.”

Interstellar Objects Such as 3I/ATLAS May Trigger Planet Formation Around High-Mass Stars

The findings of 1I/Oumuamua, 2I/Borisov, and 3I/ATLAS have revealed a substantial number of interstellar objects in the cosmos. Their widespread presence suggests that such objects are also found in protoplanetary disks, essential sites for planet formation. In these disks, interstellar objects could potentially bypass the 1-meter (3.3-foot) barrier in the traditional model of planet formation, initiating the creation of giant exoplanets.

This colorized image was taken by the CaSSIS instrument aboard ESA’s Trace Gas Orbiter on October 3, 2025, and displays the interstellar comet 3I/ATLAS. Image credit: ESA/TGO/CaSSIS.

Interstellar objects, including asteroids and comets, are those that have been expelled from their original star systems and are now traversing interstellar space, occasionally intersecting with other star systems.

Since 2017, astronomers have identified three interstellar objects passing through our solar system: 1I/’Oumuamua, 2I/Borisov, and the latest, 3I/ATLAS.

“Nevertheless, interstellar objects may exert a more significant influence than it appears at first glance,” states Professor Susanne Falzner, an astronomer at Jülich National Park.

“Interstellar objects could potentially incite planet formation, particularly around high-mass stars.”

Planets are formed from dusty disks that surround young stars through a process known as accretion. This theory posits that smaller particles gradually coalesce into larger objects, culminating in the formation of planet-sized bodies.

However, researchers have faced challenges in explaining how accretion can create objects larger than a meter amidst the chaotic collisions of planet-forming disks surrounding young stars. In simulations, the rocks tend to either bounce off each other or break apart upon collision, rather than adhering together.

Interstellar objects might help circumvent this issue. The researchers’ model illustrates how the dust-laden disks surrounding young stars can gravitationally capture millions of interstellar objects akin to 1I/’Oumuamua, which is estimated to be around 100 meters (328 feet) long.

“Interstellar space will supply ready-made seeds for the next phase of planet formation,” said Professor Falzner.

If interstellar objects could act as seeds for planets, it would also resolve another enigma.

Gas giant planets like Jupiter are scarce around smaller and colder stars, referred to as M dwarfs, but are more frequently found around larger stars similar to the Sun.

However, the lifespan of a planet-forming disk around a Sun-like star lasts only about 2 million years before dissipating, complicating the formation of gas giant planets in such a brief time frame.

That said, if captured interstellar objects serve as seeds for accretion, the planet-forming process could hasten, allowing giant planets to form within the lifetime of the disk.

“The more massive a star is, the more effectively it can capture interstellar objects in its disk,” Professor Falzner explained.

“As a result, planet formation seeded with interstellar objects should proceed more efficiently around these stars, offering a rapid pathway to forming giant planets.”

“And their swift formation is precisely what we’ve observed.”

Professor Falzner presented her findings in September 2025 during the EPSC-DPS2025 joint meeting in Helsinki, Finland.

Two Greenish Comets Illuminate the Night Sky This Month.

This autumn, two greenish comets are traversing the inner solar system, presenting a unique opportunity to view them in the coming weeks.

The comets, designated C/2025 A6 (Lemon) and C/2025 R2 (SWAN), are currently observable from the Northern Hemisphere as they journey through our cosmic vicinity.

It is quite uncommon for a comet to be visible twice within the same month.

Both comets can be observed with binoculars or small telescopes until the end of October. Comet Lemon may become visible to the naked eye around its closest approach to Earth and peak brightness on or about October 21st.

Several astronomy enthusiasts have already spotted this icy traveler.

Astrophotographer Julian de Winter, a junior lecturer at the University of Mons in Belgium, captured Comet Lemon’s striking emerald glow and elongated tail from Texas in late September.

The faint green hue arises from carbon in the gas cloud enveloping the comet’s nucleus.

In the Northern Hemisphere, Comet Lemon will appear near the Big Dipper before dawn from now until mid-month. According to EarthSky, a site focused on astronomy and skywatching, the best viewing time is in the northeast sky, just beneath the distinctive bowl and handle of the Big Dipper.

In about a week, the comet will rise in the western sky and can be seen in the evening sky. From then until the month’s end, visibility of these celestial objects may be challenging, although they might be seen with the naked eye.

Comet Swan is visible in the evening sky until the end of the month. The prime time to locate it is about 90 minutes post-sunset, directed towards the southwest. This comet may not be bright enough for naked-eye observation, so binoculars or a small telescope will be necessary.

In the coming days, Comet Swan will ascend higher in the horizon post-sunset and could brighten as it nears its closest approach to Earth around October 20th.

Under optimal conditions of clear, dark skies with minimal light pollution, it may even be possible to see both comets on the same night towards the month’s end.

Discovered in January by the Lemmon Mission, Comet Lemmon tracks near-Earth objects using telescopes located in Arizona’s Santa Catalina Mountains.

Comet SWAN was identified more recently by amateur astronomers in early September while examining images from NASA’s Solar and Heliospheric Observatory’s SWAN instrument, which has been studying the Sun since its launch in 1995.

Additionally, this month, another type of comet—one originating from outside our solar system—is passing through. Comet 3I/ATLAS, the third identified interstellar visitor, was recently photographed by a spacecraft orbiting Mars and is set to make its closest approach to the Sun around October 30th.

Please Clarify: Why Are Runners and Riders Concerned About the Strava and Garmin Feud?

Josh, there’s been quite the buzz online among runners and cyclists regarding Strava’s lawsuit against Garmin. As a runner, I must admit that I hit the pavement to escape reality, not to get involved in more online debates. What is going on?


Miles, Strava is the essential app for runners and cyclists to log their workouts. Its social features enable users to compete against each other’s times in a friendly rivalry and discover popular exercise spots.

If you’re eager to showcase your workouts to everyone, this is the Instagram for fitness.

While workouts can be tracked via smartphones or Strava’s integrated GPS, many prefer wearing fitness watches for their perceived accuracy. This is where Garmin comes into play. Strava lets Garmin fitness tracking watches interface with its app through Garmin Connect.

The collaboration between both companies has worked well for several years, but now Strava is suing Garmin in US court, claiming that Garmin has infringed on two of Strava’s patents: segments and heatmaps.


Segments and heatmaps… I’m feeling lost.

Segments allow users to monitor their times on specific sections of a route and compare against others, while heatmaps help users identify popular locations for running worldwide.

Strava alleges that Garmin has copied these features, thus violating a 10-year-old agreement they had where Garmin promised not to reverse engineer certain functionalities of the Strava app.

But why do runners seem so obsessed with their sport (see what I did there)? Why does my Reddit feed overflow with enthusiastic runners?

Perhaps you’ve heard someone annoying say, “If it wasn’t on Strava, it didn’t happen.” Runners fixate on their metrics and strive for the quickest segment times. It almost resembles a cult. Some people are even sharing coffee mugs, t-shirts, and their unique creations, with wedding photos on Strava.

The surge of Strava coincides with the running boom, and like other cultural shifts, it’s manifesting both in real life and online. Strava simplifies data sharing, making it a hotspot for fitness influencers.

Despite some unrest since early November regarding Garmin compelling users to watermark Strava workouts with Garmin device details, much of the backlash centers on Strava’s lawsuit that may impede users from sharing their runs.

Some users worry that this conflict might hinder their workout plans, with reports like tracking no longer available. Others express that while they enjoy the Strava app, it feels too closely associated with their Garmin devices for comfort. Tracking training.

One user pointed out that much of the data forming Strava’s heat maps is sourced from Garmin users, meaning a lack of this data could spell trouble for Strava.

So what does Strava seek from Garmin? Or are they just looking to end the partnership?

Matt Salazar, Strava’s Chief Product Officer, addressed the situation on Reddit recently. He indicated the lawsuit was filed after Garmin mandated Strava to comply with new watermarking protocols, which threatened the continuation of Garmin data usage by November 1st. This lawsuit attempts to address that issue.

In its court filings, Strava is demanding Garmin halt the sale of devices that allegedly infringe on their patents.

Salazar’s Reddit post bore the title “Setting the record straight on Garmin.” However, comments under his post revealed users stating they would stop using Strava if it were discontinued, accusing Strava of hypocrisy regarding its claims to safeguard user data.

Currently, Garmin has yet to comment on the allegations or requests for statements. The company plans to hold a conference call for investors later this month, ahead of the Strava deadline on November 1st, so we can expect more information then.

What steps should runners take? Which side should they support in this clash?

If you head out for a run and it doesn’t appear on Strava or Garmin, remember, it truly took place. Log off, lace up, and reconnect with nature.

Physicists Explore the Moments When Nature’s Strongest Forces Diminish

STAR detector of the relativistic heavy ion collider

Brookhaven National Laboratory

We are making strides toward comprehending when the powerful nuclear force weakens its influence on the most basic components of matter, causing quarks and gluons within particles to suddenly morph into a hot soup of particles.

There exist unique combinations of temperature and pressure where all three phases of water (liquid, ice, and vapor) coexist simultaneously. For years, scientists have sought similar “critical points” in matter impacted by the potent nuclear force that binds quarks and gluons into protons and neutrons.

In a particle collider, when ions collide, the strong force is disrupted, resulting in a state where quarks and gluons form a soup-like “quark-gluon plasma.” However, it remains uncertain if there is a tipping point preceding this transition. Shinto Researchers at the Lawrence Berkeley National Laboratory in California are getting closer to unraveling this mystery.

They assessed the number and distribution of particles produced after the collision of two high-energy gold ions at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in New York. Dong mentioned they were essentially attempting to formulate a phase diagram for quarks and gluons, depicting what types of matter are generated by strong forces under varied conditions. Although the new experiment did not definitively locate the critical point on this diagram, it significantly narrowed the possible area for its existence.

The phase diagram indicates a region where the material gradually “melts” into plasma, akin to butter softening on a countertop, but a critical point would correspond to a more sudden transition, similar to a chunk of ice unexpectedly forming in liquid water. Agnieszka Sorensen from the Rare Isotope Beam Facility in Michigan, which was not part of the study, stated that this new experiment not only guides researchers in pinpointing this critical point but also uncovers which particle properties might best indicate its presence.

Claudia Ratti from the University of Houston in Texas emphasized that many researchers eagerly anticipated the new analysis due to its precision, which surpasses that of previous measurements, particularly in parts of phase diagrams difficult to theoretically compute. She noted that several predictions regarding the critical point’s location have recently converged, and the challenge for experimenters will now be to analyze data at even lower collision energies that align with these predictions.

Dong remarked that the clear detection of the tipping point would mark a generational milestone. This is significant as the only fundamental force suspected of possessing a critical point is the strong force, which has played a crucial role in the universe’s formation. It governs the characteristics of the hot, dense matter created shortly after the Big Bang and continues to influence the structure of neutron stars. Dong concluded that collider experiments like this one could deepen our understanding of these exotic celestial objects once the strong force phase diagram is finalized.

This Chilling Snake Uses Its Spider-Like Tail as Lure in Captivating Photo

The spider-tailed viper embodies the essence of two widely feared creatures: arachnophobia (the fear of spiders) and ophidiophobia (the fear of snakes).

Imagine the only scenario where you might confront both fears: donning a clown costume (a fear of heights) and dangling from a high ledge (another fear of heights).

Nevertheless, this scenario is improbable. The spider-tailed viper typically resides in the rocky crevices of the Zagros Mountains, straddling the borders of Iraq and Iran.

Its name derives from its extraordinary tail, which mimics a spider with a swollen tip adorned with elongated “leggy” scales.

The first documented specimen was captured in 1968 and preserved in formaldehyde. When researchers from the Field Museum of Natural History in Chicago examined it two years later, they initially mistook it for a Persian horned snake, which is prevalent in the Middle East.

Initially, the spider-like appendage on the snake’s tail was thought to be a spider that inadvertently ended up in the jar. However, further examination revealed that the peculiar ornament was actually part of the snake’s tail.

The significance of this unusual anatomical feature remained ambiguous, with speculation about it being a rare anomaly linked to a parasite or tumor.

Watch a snake hunt in this clip from the BBC documentary Seven Worlds, One Planet.

In 2003, a second specimen was discovered in a damaged state, yet still exhibiting the same tail’s adornment.

The snake was identified as a new species, Pseudocerastes uralachnoides, which translates to “false horn with a spider-like tail,” sparking curiosity among researchers about whether this reptile uses its tail as a lure.

While it may sound peculiar, numerous predators utilize parts of their bodies to draw in prey. For instance, monkfish develop bioluminescent lures protruding from their heads.

The tufted wobbegong shark boasts a caudal fin that resembles a fish. Additionally, over 50 snake species are known to employ a technique called caudal luring, where they wag their tails to entice prey.

What makes the spider-tailed viper exceptional is that it is the only species known to have evolved a “caboose” that closely resembles a large arachnid.

It took thirty years for scientists to ultimately validate their hypothesis about its caudal luring technique. They set up camp in the arid mountains of Ilam province in western Iran and captured footage of six successful spider-tailed viper hunts, all occurring…

During these hunts, the snake wagged its spider-like tail, capturing the attention of nearby birds. As the birds approached, the snake struck and injected venom, resulting in the bird’s swift demise. Minutes later, the bird was consumed whole.

Spring marks peak hunting season, coinciding with birds nesting and feeding their young. However, juvenile spider-tailed vipers must adopt different hunting methods.

These young snakes hatch without their distinctive “spider butt” and develop it as they grow. Until reaching maturity, they are believed to prey on small mammals and amphibians.

The lesson here: if you’re trekking through the Zagros Mountains and spot a peculiar-looking spider, it’s best to keep your distance.

We don’t fully understand the effects of snake venom on humans, so you may want to avoid that curiosity altogether.

RadioAstron Reveals Stunning Images of Two Orbiting Supermassive Black Holes

Astronomers leveraged data from the Radio Astron satellite to generate radio images of two supermassive black holes located at the core of a distant quasar, OJ287. The secondary black hole follows a 12-year orbit around the primary black hole.



The RadioAstron will map two supermassive black holes at the center of galaxy OJ 287, located about 5 billion light-years away in the constellation Cancer. The middle component corresponds to a primary black hole, while the next higher component indicates a secondary black hole, and the highest component represents the knot of its jet. The apparent elongation of the individual components is not real but rather reflects the beam’s shape. Image credit: Valtonen et al., doi: 10.3847/1538-4357/ae057e.

Quasars are exceptionally luminous galactic nuclei whose brightness arises when a supermassive black hole at the galaxy’s center consumes surrounding cosmic gas and dust.

Previously, astronomers have successfully captured images of a black hole at the center of the Milky Way and another in the nearby galaxy known as Messier 87.

“Quasar OJ 287 is so luminous that even amateur astronomers using commercial telescopes can observe it,” remarked Dr. Mauri Valtonen, an astronomer from the University of Turku.

“What sets OJ 287 apart is that it is believed to have two black holes that orbit each other every 12 years, creating a distinct pattern of light fluctuations over the same interval.”

“The earliest observations of OJ 287 date back to the 19th century, captured through old photographs.”

“At that time, the concept of black holes, not to mention quasars, was unimaginable.”

“OJ 287 was inadvertently captured in photographs while astronomers were focused on other celestial objects.”

In 1982, Dr. Valtonen observed that the brightness of the object varied regularly over a 12-year cycle.

He continued his research as a university scholar and proposed that these brightness variations could be due to two black holes orbiting one another.

Numerous astronomers have been closely monitoring quasars to validate this theory and to gain a comprehensive understanding of the orbital motion of the black holes.

The mystery regarding this orbit was finally clarified four years ago by astronomer Lankeswar Dey from the University of Turku.

The only remaining question was whether both black holes could be detected simultaneously.

The solution came from NASA’s TESS satellite, which identified light emission from both black holes.

However, the images captured under normal light lacked the resolution to distinguish the black holes as separate entities, so they were still represented merely as single points.

What was necessary were images with a resolution 100,000 times greater than that attainable by standard radio telescopes.

In this research, Valtonen and his collaborators compared initial theoretical models with radio images.

The two black holes were precisely positioned in the images where they were anticipated to be.

This finding successfully addressed a question that had lingered for four decades: the existence of black hole pairs.

“For the first time, we were able to create images revealing two black holes in orbit around each other,” noted Dr. Valtonen.

“In the image, the black hole is marked by the powerful jets of particles it emits.”

“While the black hole itself is entirely black, it can be identified by the jets of particles and the luminous gas surrounding it.”

Researchers also discovered a completely new type of jet emanating from black holes.

The jet from the secondary black hole of OJ 287 is twisted, resembling the jet from a spinning garden hose.

“This is due to the smaller black hole moving more swiftly around the primary black hole, causing its jet to be deflected according to its current trajectory,” the authors explained.

Their paper was published in the Astrophysical Journal.

Sam Altman: The Man Who Took Copyright Rights—Can He Transform the Future by Revisiting the Past?

TTake a look at Sam Altman. Seriously, check Google Images, and you’ll notice an abundance of photos featuring the endearing Lost Puppy from Silicon Valley, showcasing the OpenAI chief sporting a clever grin. Yet, I suggest hiding the lower half of his face in these images. Suddenly, Sam’s expression takes on the haunting gaze of the boyfriend of a missing woman, pleading for her return: “Please come home, Sheila. We’re worried about you, and we just want you back.”

Don’t be alarmed if the humor feels misplaced, crude, or somewhat manipulative. I rely on OpenAI’s guiding principle: reciprocity. Content creators must formalize and painstakingly select subjects for use in generated content. outside to be utilized in any manner users see fit. I haven’t received any word from Sam, leading me to believe I know precisely where he is because I placed Sheila there. After all, he seems to fit the archetype that often accompanies the term “visibly.”

For Sam, the past fortnight has revolved around the debut of the AI video generator Sora 2 (a remarkable enhancement from the Sora of just ten months prior) and his entanglement in issues surrounding copyrighted content. Additionally, there were announcements about further interconnected transactions involving OpenAI and chip manufacturers like: Nvidia and AMD. This has led to the OpenAI frenzy, with total transaction volume surpassing $1 trillion just this year. While you can enjoy videos showcasing meticulously designed characters manipulated into digital puppets by uncreative, bigoted individuals, it also means that with OpenAI, you could lose your home in a disastrous financial collapse if the bubble bursts.

I don’t wish to offend the creators of Sora. I’ve strolled through art galleries and realized that if I were to deface an artwork with a ridiculous doodle, it would surprisingly add value; hence, if I didn’t want it, I wouldn’t have exposed it to the public. Moreover, none of the tech giants seem to lead a civilized life, so they probably cannot fathom any creative value worth preserving from being tarnished for profit. If you’ve followed Sam’s frequent reading lists, you’ll see it’s akin to the “Business Philosophy” section of a mediocre airport bookstore. This week, they mainly wanted to convey that Sora 2 is about being cool and fun. “Seeing your feed filled with memes about yourself isn’t as bizarre as you might think,” Sam assured us. So all is well! Though, I think it’s beneficial to note that while you’re inundated with simulated revenge content in a modern-day version of Byzantium, you’re also one of the most influential individuals globally profiting immensely from it. confuse “guardrail.”


I’ve heard people propose that OpenAI’s motto should be “It’s better to ask for forgiveness than permission,” but that misplaces the priority. Its real motto appears to be, “We do what we wish, and you simply deal with it.” Consider Altman’s recent political trajectory. “For those familiar with German history in the 1930s” Sam forewarned back in 2016, reflecting on Trump’s actions. It seems he has reconciled this concern in time to join. Donald Trump’s second inauguration. Perhaps, to extend his well-crafted analogy, it’s due to him being among the entrepreneurs welcomed into the Prime Minister’s office to claim their portion of the gains. “Thank you for being such a pro-business, pro-innovation president,” Sam effused to Trump at a recent White House dinner for tech executives. “It’s a refreshing change.” Unsurprisingly, the Trump administration has chosen to evade AI regulation entirely.

On the flip side, recall what Sam and his skeptical comrades stated earlier this year when it was suggested that the Chinese AI chatbot DeepSeek might have leveraged some of OpenAI’s work. His organization issued a concerned statement, asserting, “We are aware of and investigating indications that DeepSeek may have improperly extracted our models. We will provide further details as we learn more.” “We are taking proactive and assertive measures to safeguard our technology.” Interestingly, OpenAI appears to be the only entity on earth with the ability to combat AI theft.

This week, Hollywood talent agencies took the initiative to coax some form of temporary silence from Altman. I posted flannel—if not in riches, then certainly in striving to establish a “new kind of engagement” with those he has openly referred to as “rights holders.” Many of us remember just a short while ago, when rights holders held all the power. Those who possess rights. In other words, the hint lies within the terminology. However, Sam embodies the post-light era. The question arises: if he is bestowing creative rights, can we genuinely believe he’s not also conferring other types of rights?

OpenAI desires what all nurturing platforms ultimately aim for: users to remain within their realm indefinitely. It is clearly poised to become the new default homepage of the internet, much like Meta once was. Are childhood privacy catastrophes, election manipulation controversies, and child exploitation crises not far off?

Skip past newsletter promotions

Because, incredibly, we have already traversed this life cycle. But I suppose we must revisit it, right? Or more accurately, since Sam’s company is advancing at an unprecedented pace, we have already done it again. Initially, we admire the enigmatic engineer Pied Piper as a brilliant and unconventional altruist, only to later uncover that he is not as he appears and that his technology poses greater risks than we comprehended, leading to our failure to regulate it, rendering us the victims. In many ways, this mirrors a poor AI reinterpretation of a film we’ve already witnessed. If Altman’s model can learn, why can’t we?

Plant Extract Serum Boosts Hair Growth in Just Weeks

Hair growth significantly enhanced after 56 days of serum use

Tsong-Min Chang et al. 2025

A serum aimed at reversing hair loss has shown promising outcomes within a two-month period. This topical treatment, formulated with plant extracts and proteins that stimulate cellular activity, demonstrated notable enhancements in hair density compared to a placebo.

Hair loss affects approximately: 50% of men and 40% of women by the time they reach 50. Various treatments, such as finasteride and minoxidil, also known as Rogaine, may be effective; however, their success can vary based on genetics and the degree of hair loss.

Researchers are exploring innovative techniques for hair regeneration, including stem cell applications. Investigations into fibroblast manipulation, a cell type crucial for connective tissue formation, and a drug aimed at revitalizing dormant hair follicles are underway.

In a unique approach, researchers from Schweitzer Biotech in Taiwan have developed a serum enriched with caffeine, commonly found in health products, alongside two proteins known to enhance cellular growth: Insulin-like growth factor-1 (IGF-1) and Fibroblast growth factor-7 (FGF-7), both displaying potential for hair follicle regeneration. Additionally, extracts from Centella asiatica, a tropical herb widely used in skincare, appear to support hair follicle health.

To evaluate efficacy, an international research team enlisted 60 adults aged 18 to 60 without severe hair loss. Participants were divided into five groups; the first group received a placebo serum devoid of active ingredients, while the second group was provided with a basic preparation of 0.1% caffeine and vitamin B5, known for its moisturizing properties. The remaining groups used this base formulation, with the third group incorporating IGF-1 and FGF-7, the fourth group including IGF-1 and FGF-7 with C. asiatica, and the fifth group receiving all components.

All participants were instructed to apply 1 milliliter of serum to their entire scalp nightly for 56 days. Improvements were observed in all groups across various measured outcomes, including hair density, thickness, and reduced hair loss. The most significant increase in hair density was found in Group 5, which saw nearly a 25% improvement—almost double that of the placebo group.

Researchers propose that C. asiatica extracts may enhance hair root strength and boost blood circulation around hair follicles. “This plant has been recognized for its anti-aging, reparative, and anti-inflammatory properties,” explains Christos Tziotsios from King’s College London. “It could be somewhat of a miracle plant. There’s stronger evidence for some of the other components in this study. For instance, IGF-1 and FGF-7 are both known to influence hair cycle dynamics.”

Tsong-Min Chang et al. (2025)

Both Tziotsios and the research team emphasize that while the study’s scale is noteworthy, extended trials are essential before a treatment utilizing this formulation can be deemed available. “This doesn’t negate its potential interest, but it’s clear that further investigation is required,” says Tziotsios. “The more we comprehend the molecular mechanisms linked to hair loss and hair biology, the closer we will be to achieving a definitive treatment.”

Google Granted Special Status by Watchdog to Enforce Changes in UK Search Practices

Google is encountering mandatory changes in its search operations within the UK, following the competition regulator’s decision to grant the company special status and impose stricter regulations.

The Competition and Markets Authority (CMA) has confirmed that Google holds a “strategic market position” (SMS) in both search and search advertising. This classification indicates that the company wields sufficient market power to necessitate a unique regulatory framework.

The regulator now has the authority to mandate alterations in how Google conducts business in these sectors, as per new digital legislation. This announcement on Friday marks the first time a tech company has been recognized with an SMS designation.

The CMA has already indicated several potential changes, such as providing internet users with the option to select a different search service through a “choice screen.” This could include AI-driven competitors like Perplexity and ChatGPT among the available options.


The CMA is also looking to ensure equitable ranking of search results and to provide publishers with greater control over the usage of their content, including responses generated by AI. Features such as AI Overview and AI Mode powered by Google’s AI are also included under the SMS classification.

The CMA clarified that its ruling does not imply any wrongdoing and that no immediate actions will be enforced. However, this year it intends to initiate discussions regarding potential alterations to Google’s operations.

Will Hayter, executive director of digital markets at the CMA, asserted that enhancing competition in realms like search and search advertising—which involves advertisers paying to appear in users’ search results—could foster new business opportunities and stimulate investment throughout the UK economy.

He stated: “Over 90% of searches in the UK are executed on Google’s platform, underscoring Google’s continued strategic role in search and search advertising.” He added, “In response to the feedback we received post our proposed decision, we have today designated Google’s search service with a strategic market position.”

Oliver Bethel, Google’s senior director of competition, expressed concerns that this decision might jeopardize UK users’ access to emerging products and services.

He commented: “Several of the intervention ideas proposed in this process could hinder innovation and growth in the UK, potentially delaying product introductions at a time when AI-based advancements are rapidly progressing.”

Tom Smith, a competition lawyer at Geradin Partners and former CMA legal director, noted that there is a substantial case against Google.

He remarked: “There exists a clear basis for eliminating some of the market distortions caused by Google’s monopolistic stance. This has already been addressed in the US and EU. Today’s ruling empowers the CMA to take similar action.”

In a separate inquiry, the CMA is evaluating whether Google’s and Apple’s mobile platforms should be classified as SMS-enabled under the newly established digital regulatory framework outlined in the Digital Markets, Competition and Consumers Act 2024.

Introducing Anamanaguchi: The Band Behind the Soundtrack for the Latest Scott Pilgrim Game and More

S
Canadian author and cartoonist Brian Lee O’Malley’s graphic novel series,
Scott Pilgrim, weaves a narrative rich with pop culture. It explores the
themes of teenage angst, love, redemption, hubris, and pride, all while
providing a distinctly Canadian perspective on emo, indie rock, and shounen manga.
This coming-of-age tale follows an initially unlikable teen navigating
the 2000s across six graphic novels filled with clever nods to everything
from Japanese manga and Western superheroes to video games and Tintin.
Notably, it has also inspired a hit movie, a Netflix animated series in
2022, and a video game released in 2010, both of which featured music
by Anamanaguchi, an indie rock band based in New York City.

“My favorite scene in the Scott Pilgrim cartoon is when Knives and Kim
are just jamming in a room together and not much happens,” laughs
Peter Berkman, one of the band’s lead songwriters and guitarists.
“It really touched my heart. It’s not a joke.”

Anamanaguchi first gained recognition for their instrumental music
utilizing video game hardware, solidifying their place as pioneers in the
chiptune genre
while still in college. During their inaugural self-funded tour, Berkman
received an unexpected email from someone at Ubisoft.

“We got an email from someone working at Ubisoft about a video game for
a Universal IP tie-in, but they didn’t elaborate. We thought, ‘Maybe a
new Alien vs. Predator game or something along those lines?’ Regardless of
the particulars, we knew we’d want to take it to the band and say yes.
I’ve always loved game and movie soundtracks.” It turned out to be an
offer to compose music for the first Scott Pilgrim video game, released in 2010.

Currently, Anamanaguchi is experiencing a resurgence. When the game
was re-released as a complete edition in 2022, the band launched the
Scott Pilgrim vs. the World: Game Soundtrack Tour. Last year, they
composed and performed music for Scott Pilgrim Takes Off, a Netflix
spinoff that offers a meta-commentary on Scott’s life. This year,
they supported Hatsune Miku at the Fortnite Festival, showcasing their
long-standing connection to the realms of video games and live music
while releasing their first album in six years, titled Anyway, in August.
This album presents an intriguing alt-rock interpretation of their signature
synth bass sounds, still echoing their 8-bit influences. They are also
in the process of creating the soundtrack for the upcoming Scott Pilgrim
game, another engaging fighting game set to launch next year.

One segment of the band is delving into analog sounds and alternative rock angst,
while another group is rejuvenating their connection to Scott Pilgrim.
“Working on the soundtrack for the new game Scott Pilgrim EX revealed how we can adjust
our record world, further embracing the soundtrack style suited for the game,” Berkman shared.

Berkman noted that in the 15 years since their last collaboration, the band has
evolved in how they approach music. They’ve gained experience as producers,
become “listeners of music,” and have an even broader appreciation for the
diverse styles within video game music.

“It’s vital to establish a connection between the player’s experience and the
narrative unfolding at that moment, even as an adversary,” Berkman elaborated.
“If the moment demands something dark, gothic, or industrial, we can deliver it.
The freedom to blend these elements in a way never done before is crucial.
[Scott Pilgrim EX developer Tribute Games] actually let me experiment with audio mixing.
The musical cues we desire are paramount to us. The way the music flows, the rhythm…
with video game soundtracks, it’s where you can truly feel the authorship.”

After experiencing the Scott Pilgrim EX demo, it’s evident that Tribute Games’
trust in the band has paid off. The music is lively and playful, cleverly bending
norms, creating prompts and expectations. The sound effects and motifs meld seamlessly
into the level’s texture. It evokes feelings reminiscent of Sea Power’s contributions
to Disco Elysium, despite the starkly different tones—pixel art, neon colors, and
the spirit of joyful adolescence.

“Tribute Games has afforded us a degree of freedom that is usually only granted
to companies that are still finding their footing,” Berkman chuckles. “Our involvement
in the development process has been refreshing compared to last time. Nightly builds
allow us to ask, ‘Is this stagnant? Do we need to add segments here?'” This level of
collaboration has deepened our understanding of arrangement and atmosphere.
This is the soundtrack we aspired to create.”

The Costs of Our Ancestors’ Evolving Intelligence

Model of Homo heidelbergensis, potentially a direct ancestor of Homo sapiens.

WHPics / Alamy

A timeline tracking genetic alterations spanning millions of years of human evolution indicates that variants linked to elevated intelligence appeared most rapidly around 500,000 years ago, succeeded by mutations that heighten the risk of mental illness.

The findings point to a “trade-off” between intellect and mental health issues in brain evolution, according to Ilan Libedinsky from the Center for Neurogenomics and Cognitive Research in Amsterdam, Netherlands.

“The genetic changes linked to mental disorders clearly involve regions of the genome associated with intelligence, indicating a significant overlap,” says Libedinsky. “[The progress in cognitive abilities] might have made our brains more susceptible to mental health issues.”

Humans branched away from our closest relatives, chimpanzees and bonobos, over 5 million years ago, with brain size tripling since then, exhibiting the fastest growth rate in the last 2 million years.

While fossils enable the examination of shifts in brain size and shape, they provide limited insights into the brain’s functional capacities.

Recently, genome-wide association studies have explored the DNA of diverse populations to identify mutations associated with traits like intelligence, brain size, height, and various diseases. Concurrently, other research teams are investigating specific mutation characteristics that imply age, facilitating the estimation of when those variants emerged.

Libedinsky and his team are pioneers in merging these methodologies to form an evolutionary chronology of genetics linked to the human brain.

“There’s no evidence that our ancestors were conscious of their behaviors or mental health issues; we can’t trace them in the paleontological record,” he notes. “We aimed to see if our genome could serve as a kind of ‘time machine’ to uncover this information.”

The research team analyzed the evolutionary roots of 33,000 genetic mutations identified in modern humans, linked to various traits such as brain structure, cognition measures, mental illnesses, and health-related characteristics like eye shape and cancer. While most genetic variations exhibit only a weak tie to traits, Libedinsky emphasizes that “these links offer a valuable starting point but are far from conclusive.”

The study revealed that most genetic variants emerged roughly between 3 million and 4,000 years ago, with a notable surge of new variants arising over the past 60,000 years. Homo sapiensexperienced significant migration out of Africa.

According to Libedinsky, mutations linked to higher cognitive skills evolved relatively recently compared to other traits. For instance, those associated with fluid intelligence (logical problem-solving in new situations) surfaced on average around 500,000 years ago, about 90,000 years after mutations related to cancer and 300,000 years later than mutations connected to metabolic functions. Following closely were the intelligence-related variants and those related to psychiatric disorders, appearing on average around 475,000 years ago.

This trend initiated approximately 300,000 years ago, continuing with the rise of numerous variants influencing cortical shape (the brain’s outer layer crucial for higher-level cognition). In the last 50,000 years, several variants associated with language have evolved, followed by variants linked to alcoholism and depression.

“Mutations influencing the fundamental structures of the nervous system emerged slightly earlier than those influencing cognition and intelligence, which is logical since a developed brain is necessary for advanced intelligence,” Libedinsky states. “Additionally, it makes sense that intelligence mutations precede mental health disorders, as these capabilities must exist before dysfunction occurs.”

These timelines align with evidence indicating that Homo sapiens obtained certain variants linked to alcohol use and mood disorders through interbreeding with Neanderthals, he added.

It remains uncertain why evolution has not eradicated variants that predispose individuals to mental health issues; however, Libedinsky suggests that their mild effects could be advantageous in certain situations.

“This area of research is thrilling because it enables scientists to revisit enduring questions in human evolution and empirically test hypotheses utilizing actual genomic data,” says Simon Fisher from the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands.

Nonetheless, this research can only assess genetic sites that vary among contemporary humans, potentially overlooking ancient, now widely shared changes pivotal to human evolution. Fisher emphasizes that developing tools to probe “fixed” genetic regions could lead to deeper understanding of our unique human characteristics.

The US Navy Trains Animals to Play Video Games: Here’s Why

You might be surprised to learn that there are many animal gamers out there. For instance, in California, U.S. Navy sea lions are trained to: manipulate a cursor on a screen using their noses to press four buttons (up, down, left, and right) to navigate through a maze.

The sea lions, utilized by the Navy for locating and retrieving underwater objects, earn real herrings as rewards for completing their tasks, as opposed to loot boxes or power-ups.

This game is specifically designed to assess the cognitive skills of the sea lions; however, they face tough competition from the Navy’s bottlenose dolphins, which have been trained to control a joystick with their mouths to play the same game.

On land, primates reign supreme as gamers. Chimpanzees and orangutans at zoos in Edinburgh, Scotland, and Leipzig, Germany, have recently been trained to forage for food in a virtual setting.

When one of them discovers a digital snack (with apples, grapes, and bananas scattered throughout the game), they are rewarded with a real-life equivalent of the food.

This game offers valuable insights into how these animals utilize landmarks, like trees, to navigate while searching for food.

Meanwhile, chimpanzees in the United States have showcased their ability to navigate virtual mazes. A 2014 survey conducted by the Language Research Center at Georgia State University revealed that they perform comparably to children aged 3 to 6 years old.

However, like sea lions, primates also face strong competition. In 2021, four pigs in the United States were taught to operate a joystick using their noses to guide a cursor on the screen to a target, a task that requires a “conceptual understanding of the task and skilled motor skills.”

There are even digital mice and tablet apps for cats that let them “catch” fish with their paws.

Where will this all lead? A hedgehog playing Sonic Racing? A hamster playing Grand Theft Auto? Perhaps not, but these animal gamers reveal that we still have much to learn about their cognitive capabilities.

Robotic Underwater Glider Embarks on Global Journey

Redwing glider during test launch

Teledyne Marine

A small robotic submarine embarks on its inaugural round-the-world journey. On October 11, New Jersey’s Teledyne Marine, in collaboration with Rutgers University-New Brunswick, will launch an underwater glider named Redwing from Martha’s Vineyard, Massachusetts, as part of its Sentinel mission.

Researchers have utilized underwater gliders since the 1990s. Unlike traditional submarines, the glider employs a buoyancy engine, which utilizes a gas-filled piston to alter its buoyancy. An electric motor moves the piston, increasing the glider’s weight to allow it to sink gradually at a gentle angle. Once it reaches around 1000 meters deep, the piston retracts, enabling the glider to ascend. This method results in a slow and steady path as it navigates its intended route. Although there is an auxiliary propeller available for use, the objective is to rely on the buoyancy mechanism.

“Redwing will harness the currents rather than fight against them, maintaining an average speed of 0.75 knots, just shy of 1 mph,” says Shea Quinn, who heads the Sentinel missions at Teledyne Marine.

Measuring 2.57 meters in length—similar to a surfboard—and weighing 171 kilograms, the Redwing boasts a robust design featuring ample batteries that enhance its durability for prolonged missions.

“The ambitious Sentinel mission is projected to complete its orbit within approximately five years,” states Brian Maguire from Teledyne Marine. Throughout the journey, Redwing will operate independently, relaying information to engineers from Teledyne Webb Institute and students from Rutgers University via satellite. Mission Control will adjust the glider’s course bi-daily to ensure it adheres to its flight itinerary. Maguire mentioned that battery replacement may be necessary during the five-year expedition.

The Redwing follows the route of explorer Ferdinand Magellan’s circumnavigation of the globe from 1519 to 1522, which included stops in Gran Canaria, Cape Town, Western Australia, New Zealand, the Falkland Islands, and possibly Brazil, ultimately returning to Cape Cod after covering 73,000 kilometers.

These gliders are invaluable for conducting long-distance research missions without requiring costly support vessels, thus playing a crucial role in gathering data essential for understanding climate change. Redwing is equipped with various instruments to monitor ocean currents and temperatures in lesser-known waters.

“We believe this to be the most sustained open-ocean sampling mission ever undertaken,” claims Maguire.

Past glider missions have achieved significant milestones, including crossing the Atlantic in 2009 and the Pacific in 2011, traversing regions like the Ross Ice Shelf that are typically unreachable. “Gliders are excellent tools for acquiring data in perilous conditions, such as during storms or hurricanes, or near melting glaciers,” explains Karen Heywood from the University of East Anglia, UK. The primary hazards to the mission include fishing nets and shipping routes rather than adverse weather; “Gliders are quite resilient and can endure harsh winds and tumultuous seas,” she added.

Alexander Phillips from the UK’s National Marine Center underscores that gliders also face challenges from marine life and biofouling—where algae and other organisms accumulate on their surfaces, which can impair functionality. “Biofouling may cause marine organisms to cling to the glider, making it non-operational. Additionally, these gliders have occasionally been lost to shark attacks or due to mishaps during transport or fishing.”

Data collected from the mission will be distributed to universities, schools, and other organizations worldwide, with the primary goal of showcasing the glider’s capabilities and inspiring future research endeavors.

Sword Dragon: The Ichthyosaur with Enormous Eyes and a Lethal Snout

Reconstruction of Siphodracon it might have looked like

Bob Nicholls

Presenting the “sword dragon,” a recently identified species of ichthyosaur, a predatory ancient reptile that ruled the oceans during the reign of the dinosaurs on land.

This exquisitely preserved fossil skeleton was unearthed in 2001 near Golden Cap on England’s Jurassic Coast and remained in museum storage for many years. Royal Ontario Museum in Canada.

Dean Lomax of the University of Manchester, UK, stated: “They recognized it was something notable.” “They intended to study it, but ultimately did not.”

Lomax and his team have carefully examined and classified a specimen with large eye sockets and a sword-like elongated snout. The fossil contains “needle-like teeth,” adapted for consuming soft-bodied prey such as squid and fish. “This provides great insight into the lifestyle of this creature while it was alive. Essentially, it likely hunted in dim environments and depended on exceptional vision,” Lomax explained.

The creature measured approximately 3 meters in length, roughly the size of a bottlenose dolphin, and is believed to have existed during the Early Jurassic period, specifically the Pliensbachian epoch, around 193 to 184 million years ago.

Its anatomical features are unprecedented among ichthyosaurs, including a distinctive lacrimal bone with an unusual structure surrounding its nostrils. “The preservation quality, especially of delicate elements like cranial sutures and the lacrimal and prefrontal processes, is remarkable,” remarked Aubrey Roberts from the Natural History Museum, University of Oslo, Norway.

The black mass found between the ribs may represent its final meal, although the researchers were unable to identify it.

Fossilized Xiphodracon Golden Capensis

Dr. Dean Lomax

This ichthyosaur has been named for its menacing snout: Siphodracon Golden Capensis, known as the golden-capped sword dragon.

This specimen also provides valuable insight into the evolution of ichthyosaurs. “The greatest significance of this discovery lies in its age,” remarked Roberts. During the latter part of the Triassic, massive superpredator ichthyosaurs such as Ichthyotitan, reaching lengths of nearly 25 meters, existed alongside species as large as blue whales, but these titans vanished following a mass extinction event at the end of the Triassic, approximately 201.4 million years ago, marking the onset of the Jurassic period.

Fossils of various smaller ichthyosaurs have been discovered that date back to the Jurassic period, as Lomax pointed out. Many have been identified since the Pliensbachian period, but no common species exist, and there are two distinct types.

“Triassic ichthyosaurs were well-known for their uniqueness,” explains Neil Kelley of Vanderbilt University, Tennessee. “Their Jurassic successors are often perceived as somewhat more uniform, sharing a superficially dolphin-like appearance.”

Siphodracon contributes another shade to the broad spectrum of ichthyosaurs,” he added, supporting evidence that Jurassic ichthyosaurs adopted a range of lifestyles, featuring diverse diets, swimming speeds, and habitat preferences.

Southern Impact Reveals Magma Ocean in Moon’s Largest Crater: Study

Approximately 4.3 billion years ago, during the early formation of our solar system, a massive asteroid collided with the far side of the moon, resulting in the creation of the South Pole-Aitken Basin—an enormous crater. This feature, the largest on the moon, spans over 1,200 miles in length and 1,000 miles in width. Its rectangular shape is attributed to a glancing impact rather than a direct hit. Challenging previous beliefs that the basin was formed by an asteroid coming from the south, recent research indicates that the narrowing shape of the basin towards the south suggests an impact from the north.



The South Pole-Aitken Impact Basin on the far side of the Moon was formed by a southward impact. Image credit: Jeff Andrews-Hanna / University of Arizona / NASA / National Astronomical Observatory of Japan.

“The downstream edge of the basin should have a thick layer of material that was excavated from the moon’s interior by the impact, while the upper edge should not,” explained Dr. Jeffrey Andrews-Hanna, a planetary scientist at the University of Arizona.

“This suggests that the Artemis mission will target the downrange rim of the basin, an ideal site to examine the moon’s largest and oldest impact basins, where most of the ejecta, consisting of material from deep within the moon, are likely to be gathered.”

Historically, it has been believed that early moons were molten due to the energy released during their formation, resulting in a magma ocean that enveloped the entire moon.

As this magma ocean solidified, heavy minerals settled to create the Moon’s mantle, while lighter minerals floated upwards to form the Earth’s crust.

Nevertheless, certain elements were not incorporated into the solid mantle and crust, but instead became concentrated in the last liquid remnants of the magma ocean.

These “residual” elements, including potassium, rare earth elements, and phosphorus, are collectively known as KREEP.

Dr. Andrews-Hanna and his team noted that these elements appear to be especially abundant on the moon’s near side.

“If you’ve ever frozen a can of soda, you might have noticed that high fructose corn syrup doesn’t freeze all the way through and instead accumulates at the bottom of the liquid,” remarked Dr. Andrews-Hanna.

“We believe a similar phenomenon occurred on the moon with KREEP.”

“Over millions of years, as it cooled, the magma ocean crystallized into the crust and mantle.”

“Eventually, only a small amount of liquid remained trapped between the mantle and the crust, which is this KREEP-rich material.”

“The abundance of KREEP’s heat-producing elements somehow concentrated on the moon’s near side, causing it to heat up and initiate intense volcanic activity, thus creating the dark volcanic plains visible from Earth.”

“However, the process by which this KREEP-rich material became concentrated on the near side and how it evolved remains an enigma.”

“The moon’s crust is considerably thicker on the far side compared to the near side that faces Earth, a discrepancy that continues to puzzle scientists.”

“This asymmetry influences various aspects of the moon’s development, including the final stages of the magma ocean.”

“Our hypothesis posits that as the far side’s crust thickened, the underlying magma ocean was forced outward, akin to squeezing toothpaste from a tube, causing most of it to accumulate on the near side.”

A recent investigation of the Antarctic Aitken Basin has uncovered unexpected asymmetries supporting this scenario. The western ejecta blanket is rich in radioactive thorium, while the eastern side is not.

This indicates that the rift left by the impact formed a conduit through the moon’s crust, near the boundary separating the “normal” crust from the underlying layers that contain the final remnants of the KREEP-rich magma ocean.

“Our research shows that the distribution and composition of these materials align with predictions derived from modeling the later stages of magma ocean evolution,” stated Dr. Andrews-Hanna.

“The last remnants of the Moon’s magma ocean have reached the near side, where the concentration of radioactive elements is at its peak.”

“However, prior to this, there may have been a thin, patchy layer of magma ocean beneath parts of the far side, explaining the presence of radioactive ejecta on one flank of the Antarctic Aitken Basin.”

For further information, refer to the study published in the journal Nature.

Hannah Ritchie’s Latest Book on Net Zero Offers a Refreshing Perspective

Geothermal power could become a crucial aspect of the UK’s future energy mix

Jim West/Alamy

purify the air
Hannah Ritchie, Chatto & Windus (UK); MIT Press (USA, published March 3, 2026)

A few weeks prior, while dining with friends, the conversation turned to renewable energy—quite fitting as we had a climate journalist, an activist, and two civil servants at the table.

As expected, my dinner companions were well-versed in the perils of climate change and the pressing necessity to transition to cleaner energy sources. However, a question lingered: Does the UK still require gas as a backup fuel for the electricity grid? Can we rely solely on wind, solar, and batteries during those dreary winter months?

In such discussions, it’s timely that data scientist Hannah Ritchie’s new book has been released. Clearing the Air: A hopeful guide to solving climate change with 50 questions and answers serves as an excellent resource. Thanks to my well-thumbed copy, I was able to guide a friend through various storage solutions that maintain grid power when wind and sunlight are scarce, highlighting the roles of pumped storage, geothermal energy, and hydrogen.

In her previous work, it’s not the end of the world, Ritchie provided a swift education on addressing the planet’s environmental challenges. purify the air, though it maintains the same optimistic outlook, functions more as a practical guide with data-driven answers regarding the journey to achieve net-zero emissions.

Topics are categorized, covering fossil fuels and renewable energy to electric vehicles and domestic heating. Reading through, it’s evident that Ritchie aims to counter the deluge of misinformation and misleading media narratives surrounding the net-zero transition. Her work dispels myths, such as the idea that electric cars will frequently run out of power on highways, heat pumps are ineffective in colder climates, and that there isn’t enough land available for solar energy installations.

purify the air wields the power of scientific research and solid data to combat this misinformation. For instance, one of her addressed questions is whether wind farms pose a threat to birds—a commonly cited criticism from figures like US President Donald Trump. The response is yes; while wind turbines do unfortunately kill some birds, the figure is minimal compared to annual deaths caused by cats, buildings, vehicles, and pesticides.

Nevertheless, wind turbines do threaten certain species, including bats, migratory birds, and birds of prey. Ritchie emphasizes that measures can be taken to mitigate these risks, such as repositioning wind farms, utilizing black paint on turbines, and deactivating blades during low wind conditions. Such nuances are often lost in headlines or political jests, yet they are key to comprehending the advantages and drawbacks of transitioning to clean energy.

The Q&A format of the book makes it approachable, although repetition may set in if read in one sitting. purify the air proves to be a handy reference when dealing with climate-change skeptics during family gatherings.

Throughout, Ritchie’s characteristic optimism shines prominently. She clarifies that viable decarbonization options are available in nearly every facet of the net-zero transition, all without shying away from real challenges or indulging in wishful thinking. The impact is profound; readers will depart informed, hopeful, and reassured that humanity can prevail in the face of the climate crisis. In a landscape rife with fake news and political deception, this book truly brings a breath of fresh air.

Treatment Could Be the Most Effective Solution for Easing Irritable Bowel Syndrome

Irritable bowel syndrome may be alleviated by techniques taught in various therapies

A new approach that alters behaviors in individuals with irritable bowel syndrome (IBS) could prove to be more effective than traditional treatments. When offered digitally, these methods might also enhance the speed of relief.

IBS is often accompanied by symptoms such as bloating, diarrhea, constipation, and abdominal pain. While the underlying cause is not entirely understood, disruptions in gut-brain signaling are thought to play a pivotal role. Factors such as intestinal infections and certain foods can irritate the gastrointestinal tract, sending distress signals to the brain, while psychological stress can trigger the opposite response. Patients with IBS are advised to explore relaxation techniques.

While dietary recommendations and medications, like laxatives, provide relief for some, others continue to struggle with symptoms. Consequently, researchers are investigating innovative alternatives, including fecal transplants. Behavioral therapy, often seen as a last resort by physicians, may actually offer greater benefits than standard care according to a 2020 review. This approach may surpass regular treatment efficacy.

Among the methods is cognitive behavioral therapy (CBT), which empowers individuals to modify their thoughts and behaviors to better cope with and accept their symptoms, and gut-directed hypnotherapy, which induces a trance-like state prior to signaling symptom improvement.

Following the release of more studies, Alexander Ford and his colleagues at the University of Leeds in the UK, some of whom contributed to earlier reviews, conducted a comprehensive review of 67 randomized controlled trials with over 7,000 participants. These trials compared behavioral interventions lasting 4 to 12 weeks against various control groups that received conventional treatments like dietary guidance and laxatives, or those on a waiting list for intervention.

“This represents the most extensive review of behavioral treatments for irritable bowel syndrome in terms of both the number of studies and participants,” stated Perjohan Lindfors from Karolinska Institutet, Sweden.

The findings indicate that CBT and gut-directed hypnotherapy, whether in-person or via apps and the internet, are more beneficial compared to standard treatments when participants evaluated their symptoms pre- and post-treatment.

Rather than typically being provided solely in-person after standard treatments fail, the results imply that behavioral therapies can be utilized much earlier in the process. Ford remarked, “Digital solutions can help expedite the delivery of these treatments.” He further mentioned that such approaches may allow for broader implementation of behavioral therapies. However, before any updates to guidelines can be made, further trials that directly compare digital therapies with traditional treatments are required, which Ford estimates could take another five years.

Additionally, as most participants were unaware of their assigned groups, a portion of the observed benefits may stem from a placebo effect, according to Lindfors. He proposed that trials involving full treatment versus partial treatment could assist in estimating the effect size, assuming all participants genuinely believed they were receiving effective behavioral therapy.

Unveiling the Ovary’s Secret Ecosystem: Its Unexpected Impact on Fertility

A novel imaging technique has uncovered an unexplored ecosystem within the ovaries that could affect the aging process of human eggs. This breakthrough may pave the way for strategies to slow ovarian aging, maintain fertility, and enhance health after menopause.

Women are born with millions of immature eggs, with one maturing each month post-puberty. However, after the late 20s, fertility declines sharply, typically attributed to diminishing egg quantity and quality.

To gain insights into this decline, Eliza Gaylord and her team at the University of California, San Francisco, developed a 3D imaging method that visualizes eggs without the need for slicing the ovaries, a traditional technique.

These newly captured images revealed that eggs cluster in pockets, rather than being uniformly distributed, indicating that the ovarian environment may significantly influence egg aging and maturation.

By integrating this imaging with single-cell transcriptomics, which identifies cells by their gene expression, researchers examined over 100,000 cells from both mouse and human ovaries. Samples were taken from mice aged 2 to 12 months and four women aged 23, 30, 37, and 58.

Through this approach, the team identified 11 major cell types and uncovered some surprises. One unexpected finding was the presence of glial cells—typically associated with the brain—that nourish and repair nerve cells, alongside sympathetic nerve cells that manage the fight-or-flight response. In mice lacking sympathetic nerves, fewer eggs matured, suggesting these nerves may influence when eggs develop.

Moreover, the researchers observed that fibroblasts, crucial for structural support, decrease with age, potentially leading to inflammation and scarring in the ovaries of women in their 50s.

This research indicates that ovarian aging is influenced beyond just the eggs; it involves the surrounding ecosystem, as noted by Diana Laird, also affiliated with UCSF. Importantly, she highlights the similarities discovered between aging ovaries in mice and humans.

“These similarities provide a basis for using laboratory mice to model human ovarian aging,” states Laird. “With this roadmap, we can start to explore the mechanisms that dictate the pace of ovarian aging to devise treatments that might slow or reverse the process.”

One potential avenue is to adjust sympathetic nerve activity to slow egg loss, thereby extending the reproductive time frame and delaying menopause.

Theoretically, this approach not only preserves fertility but may also diminish the risk of common postmenopausal conditions, including heart disease. “While later menopause could increase the risk for some reproductive cancers, this pales in comparison to the 20-fold higher risk of death from cardiovascular disease post-menopause,” explaines Laird.

However, such interventions are likely still far in the future. Evelyn Telfer, a researcher at the University of Edinburgh—known for being the first to successfully culture human eggs outside the ovary—points out that the limited age range and samples from just four women restrict the applicability of the findings. “Though intriguing, this study’s results are too preliminary to support treatment strategies aimed at altering follicle utilization or slowing egg loss,” she notes.

Spiral Lasers Can Manage Their Unruly Magnetic Counterparts

Materials resembling magnets exhibit internal spirals that can solely be controlled with circularly polarized lasers.

Scientists have successfully regulated the behavior of a previously elusive material, akin to magnetism, which may eventually lead to improved hard drives.

When a bar magnet is introduced to a magnetic field, it rotates due to that influence. However, materials characterized by a property called strong axis remain stationary under all known magnetic fields. Recently, Zeng Zhiyang and his team at the Max Planck Institute for the Structure and Mechanics of Matter in Germany discovered a method to manipulate strong-axis properties using lasers.

A conventional magnetic material is often thought of as a collection of many small bar magnets. Zeng explains that for strong-axis materials, it is more accurate to envision a group of dipoles (two opposing charges separated by a small distance) swirling in a minor spiral. He and his team realized they could control these vortices with laser pulses containing a specific swirl.

The researchers adjusted the laser to emit circularly polarized light. Upon striking a strong-axis material (specifically a compound made of rubidium, iron, molybdenum, and oxygen), it induced rotation in the material’s atoms, altering the dipole’s direction of motion.

Team member Michael Forst from the Max Planck Institute for Structure and Mechanics of Matter remarked that while it has been established that light can effectively control materials—transforming conductors into insulators and vice versa—tailoring light’s properties for material control has presented a significant technical challenge.

“This serves as a strong proof of concept,” notes Theo Rasing at Radboud University in the Netherlands. He adds that this material adds to the growing array of options for constructing more efficient and stable memory devices, such as hard drives that store information in electromagnetic charge patterns.

However, the current experiments necessitate cooling the material to approximately -70°C.°C (-94°F). Additionally, because the team’s laser was relatively large, Forst indicates that more development is required before a practical device can realistically be constructed.

Uncovering a New Factor Behind the Longevity of Naked Mole Rats

Investigation into naked mole rats may unveil novel anti-aging methods

Janissimo/Shutterstock

Naked mole rats can live for up to 37 years, significantly outliving other rodents of a similar size. So, what accounts for their remarkable lifespan? Research indicates that variations in immune proteins that enhance DNA repair may play a role, among other elements.

This discovery suggests the potential for developing treatments aimed at increasing human longevity, according to Mao Jiyong from Tongji University in Shanghai, China. This finding also supports the notion that the accumulation of mutations and the inability to repair damaged DNA are primary contributors to aging.

The immune protein in focus is called cGAS, found in many organisms. It is primarily thought to function as an alert mechanism in response to DNA detected outside the nucleus, which could indicate cancer or viral invaders.

Interestingly, cGAS is also found within the cell nucleus. In both humans and mice, it has been shown to hinder DNA repair while elevating mutation rates and cancer risk. The precise reasons for this are still unclear and might be an unintended consequence rather than a beneficial adaptation.

Mao and his team have demonstrated that the cGAS variant present in naked mole rats exhibits the opposite behavior in the nucleus, actively promoting DNA repair. This is linked to differences in four amino acids that constitute the cGAS protein. When these amino acids are altered in a mole rat’s cells, their cGAS loses its ability to facilitate DNA repair. Conversely, modifications to the human cGAS can remove its inhibitory effect on DNA repair.

Additionally, when the researchers genetically modified fruit flies to express the naked mole rat version of cGAS, those flies lived nearly 70 days, in contrast to the approximate 60 days lifespan of the unaltered flies.

So, could we enhance our lifespans by introducing naked mole rat cGAS into human cells? “Yes, employing gene editing and mRNA delivery might provide avenues to enhance DNA repair and increase human longevity,” Mao asserts. However, achieving sufficient levels of the crucial cells to produce the modified cGAS poses a challenge.

Alternatively, researchers could seek small-molecule drugs that can interact with the human cGAS protein, prompting it to act more like its mole rat counterpart, Mao suggests.

This study indicates that cGAS does have an impact on lifespan. Additionally, Vera Gorbunova and her research team at the University of Rochester in New York have discovered that a molecule known as hyaluronic acid also plays a role in the notable longevity of naked mole rats. “[Thus,] altering cGAS activity through pharmacological or genetic strategies could yield beneficial outcomes for health and longevity,” she concludes.

Report Claims Gen Z Confronts ‘Employment Crisis’ as Global Firms Favor AI over Hiring

As young individuals enter the job market, they are encountering what some are calling an “employment apocalypse.” This is due to business leaders opting to invest in artificial intelligence (AI) over new hires, as revealed in a survey of global executives.

A report by the British Standards Institute (BSI) indicated that rather than nurturing junior employees, employers are focusing on AI automation to bridge skill gaps and enable layoffs.

In a study involving over 850 business leaders from seven countries—namely the UK, US, France, Germany, Australia, China, and Japan—41% of respondents reported that AI has facilitated a reduction in their workforce.

Nearly a third (31%) stated their organizations are considering AI solutions before hiring new talent, with two-fifths planning to do so in the next five years.

Highlighting the difficulties faced by Gen Z workers (born from 1997 to 2012) in a cooling labor market, a quarter of executives believe that AI could perform all or most tasks currently handled by entry-level staff.

Susan Taylor-Martin, CEO of BSI, commented: “AI offers significant opportunities for companies worldwide. However, as firms strive for enhanced productivity and efficiency, we must remember that humans ultimately drive progress.

“Our findings show that balancing the benefits of AI with supporting the workforce is a key challenge of this era. Alongside our AI investments, long-term thinking and workforce development are crucial for sustainable and productive employment.”

Additionally, 39% of leaders reported that entry-level roles have already been diminished or eliminated due to the efficiencies gained from AI in tasks like research and administration.

More than half of the respondents expressed relief that they commenced their careers before AI became prevalent, yet 53% felt that the advantages of AI in their organizations outweigh the disruptions to the workforce.

UK businesses are rapidly embracing AI, with 76% of leaders anticipating that new tools will yield tangible benefits within the next year.

Executives noted that the primary motivations behind AI investments are to enhance productivity and efficiency, cut costs, and address skills gaps.

An analysis from BSI of companies’ annual reports revealed that the term ‘automation’ appeared almost seven times more frequently than ‘upskilling’ or ‘retraining.’

Additionally, a recent poll from the Trades Union Congress found that half of British adults are apprehensive about AI’s impact on their jobs, fearing that AI may displace them.

Recent months have seen the UK’s job market cool, with wage growth decelerating and the unemployment rate rising to 4.7%, the highest in four years. Nevertheless, most economists attribute this not to a surge in AI investments.

Conversely, there are worries that the inflated valuations of AI companies could spark a stock market bubble, potentially leading to a market crash.

A Non-Profit Empowering Aspiring Game Developers Worldwide

Gamescom is an extraordinary video game convention that takes place each year in Cologne, Germany. Each year, hundreds of thousands of gamers converge to fill large convention spaces, alongside industry professionals who have the chance to distribute games to fans and present their resumes to developers. For companies located outside the United States, this is the premier event of the year. This marks the first year for the International Game Developers Association (IGDA) Foundation, and Executive Director Alyssa Walles is eager about the opportunities it presents.

The IGDA Foundation focuses on providing professional development for underrepresented and marginalized individuals seeking to enter the video game industry. This initiative is vital, considering the numerous obstacles faced by aspiring producers, developers, and writers. While Ms. Walles has been with the IGDA Foundation for just three years, she brings a wealth of experience from her long-standing career in the video game industry. She understands the importance of supporting those who do not have the advantages of privilege, those who lack the means to travel globally for competitions, or those without formal training in computer design and coding.

“I was part of the launch team for PlayStation in Europe, and most of the time I was the only woman in the room,” Wallace recalls. “So I’m thrilled to witness this change.” Nevertheless, she recognizes that more effort is needed.

The IGDA Foundation initially began by sponsoring a select number of individuals to attend the annual Game Developers Conference in San Francisco. This costly endeavor often prevents hundreds of developers from marginalized communities and remote regions from participating. When the COVID-19 pandemic altered the landscape of video gaming events, the IGDA Foundation had to innovate. This led to the creation of Virtual Exchange by former executive director Nika Noor—a six-week online initiative that connects grantees with experienced gaming industry mentors. Each year, the IGDA Foundation reviews hundreds of applications and selects grantees based on three main categories: gaming career professionals aspiring to advance, individuals looking to transition into gaming, and recent graduates.

Walles shared: “A standout example from our network is a young man from Nigeria who has experience in home building and project management. He constructs houses daily and also programs. He hopes to leverage his project management skills to transition into becoming a video game producer.”

For Wallace and other seasoned industry veterans leading the IGDA Foundation, the mission is about channeling their experiences to foster a robust and diverse future for the industry. “I’m 65 years old and I’m not shy about it…I’m nearing the end of my career, so I’m here to give back,” she states.

However, the IGDA Foundation, like many initiatives aimed at improving equity within the video game and technology sectors, has faced significant hurdles recently. Following rapid growth during the pandemic, the industry saw unprecedented layoffs. Companies inform Wallace that funding for the foundation is nonexistent, a claim she finds hard to believe (“I know you have $5,000”). Although the IGDA Foundation does not receive government support, there have been attacks from the Trump administration and Elon Musk’s Department of Government Efficiency (Doge) against diversity, equity, and inclusion initiatives, compelling organizations to reassess their marketing strategies and donor outreach.

“Some nonprofits in our sector have been forced to shut down, but thankfully, we’re not close to that point. Still, I worry about it constantly,” Wallace confesses. “How can we connect with individuals wanting to earn a substantial income in the gaming world and nurture the upcoming generation?”

The virtual exchange program for 2025 is now operational. Photo: Provided by IGDA Foundation

Yet, under Wallace’s direction, the IGDA Foundation is unafraid to innovate. Last year, she found an article in a newsletter about an independent developer making significant profits from a single downloadable content (DLC) in a Steam bundle. “We reached out to the IDGA Foundation’s alumni network and proposed organizing a Steam event featuring DLC,” she explains. Someone from the network volunteered to run it. This led to the initiation of an event called Download for Charity, held in May, which included 24 participating games and raised $24,000,” says Walles. She also organizes game jams in collaboration with diverse partners and recently launched a porting initiative to assist developers in adapting their games for Android devices.

This relentless pursuit of funding exemplifies Wallace’s commitment to the program and the marginalized communities it supports. Wallace’s aspirations for the IGDA Foundation are straightforward. “We simply want adequate funding to sustain our efforts so we can deliver these programs to individuals in need across the globe.”

We’re Surprised to Discover That Not All Roses Have Thorns.

Feedback is new scientist A popular person who watches the latest science and technology news sideways. To send feedback on items you think might be of interest to our readers, please send an email to feedback@newscientist.com.

There is a tingling sensation

We don’t want to overstate this in Feedback, but we believe we’ve uncovered a revelation that could transform vast areas of music and literature and compel us to reconsider one of our most cherished metaphors.

It all began when I wrote about an educator utilizing a Taylor Swift music video to introduce students to botany (September 27). Reader Gerald Legg reached out to highlight some errors. First, one of the topics mentioned was “Lightning Races,” which should obviously have been “lighting.” In our defense, the original academic paper we consulted also contained that mistake.

However, it was Gerald’s second point that sent the feedback into a spiral. As a side joke, I once remarked, “Botany is a rose garden full of thorns” (if you don’t get the reference, you’d assume there’s a blank space where Taylor Swift’s refrain fits).

Gerald responded, “I’m sorry, but botany isn’t merely a rose garden filled with thorns, unless you’re referring to shrubs like blackthorn. Roses don’t have true thorns; what they exhibit are superficial epidermal growths, while thorns are modified stems.”

Feedback was sent to selected search engines and consulted expert sources, including the New York Botanical Garden website. We ultimately conceded that roses do indeed lack thorns. Those sharp protrusions are thorny.

The issue lies in the fact that this distinction doesn’t only invalidate Feedback’s quips or Swift’s lyrics. For starters, William Shakespeare must be reinterpreted in two instances: in Sonnet 54, he cautions readers, “Canker flowers are full of dark dyes / Like rose-scented tinctures / Hold on to those thorns,” which is entirely inaccurate. Furthermore, in Sonnet 35, he states, “You needn’t grieve anymore for what you’ve done / There are thorns in roses and mud in silver fountains.”

Similarly, Henry Van Dyke should have titled his poem “Thorns and Roses,” as he asserts, “Far richer than a rose without thorns / Its branches of beauty never shine.”

Feedback is leading me to question whether literal representations of plants can effectively function in poetry or song. Nevertheless, there are silver linings. The works of Johann von Goethe will remain intact because he merely states that “a small rose stung in defense of itself,” without specifying the appendage involved.

And happily, a poignant power ballad, “Every Rose Has Its Thorn” by Hair Metal Purveyor Poison, can be safely discarded. Every cloud contains a glimmer of hope.

Sperm tracking

Earlier this year, Feedback dedicated several columns to the Scunthorpe issue. Innocuous words and phrases often include character strings that can appear offensive when viewed out of context, complicating the development of automated tools to manage online conversations (April 26).

We thought the topic had been exhausted, but educator and researcher Bernd Wursig informed us otherwise. In the early 2000s, Wursig led a team studying sperm whales in the Gulf of Mexico, and attentive readers may guess where this leads.

One of the researchers submitted daily reports via satellite phone, but only about half were received. Eventually, they discovered that many of these reports contained the word “sperm,” causing the university’s servers to delete them.

They circumvented this issue by crafting reports that read, “We photographed and tracked whale matriarchal societies.”

Just one letter

We continue to seek out the most inspiring or amusing scientific abbreviations.

Christina Cheers kicks things off by focusing on the Australian Center for Disease Control. She describes it as a biosafety laboratory that studies “highly contagious animal diseases.”

Over its 40-year history, the center has undergone several name changes. The current title was adopted in April 2020. Previously, it was known as the Australian Institute of Animal Health. However, Christina revealed that it had another name at its inception.

In its early development stages, it was called the Australian National Institute of Animal Health, until a few scientists raised concerns about how it was referred to by its acronym. Consequently, “National” was dropped.

Curiously, Feedback couldn’t find any mention of this little acronym mishap on the center’s website. However, after some digging, I found an article in the Australian Veterinary Journal, published since 1974, discussing the proposed laboratory and its benefits. The piece repeatedly refers to it as the Australian National Institute of Animal Health, even employing the unfortunate acronym.

For truly complex acronyms, consider Niall Leighton’s suggestion. This is a European research project that investigates “how online narratives containing conspiracy theories and misinformation spread and evolve, with a focus on individuals aged 45 to 65.” (You might not catch this in New Scientist.)

The project is titled “The Story of Social Media: Tackling Extremism in Midlife.” This should shorten to SMNAEM(A) but is inexplicably condensed to SMIDGE. Niall explains it works like this (“But I guess”): Social Media Narrative: Countering Extremism in mIDdle-aGE.

If anyone can top that, they are truly clever and humble.

Age Verification Hacking Firm Possibly Exposes ID Photos of Discord Users | Social Media

Photos of government IDs belonging to approximately 70,000 global Discord users, a widely used messaging and chat application amongst gamers, might have been exposed following a breach at the firm responsible for conducting age verification procedures.

Along with the ID photos, details such as users’ names, email addresses, other contact information, IP addresses, and interactions with Discord customer support could also have fallen prey to the hackers. The attacker is reportedly demanding a ransom from the company. Fortunately, full credit card information or passwords were not compromised.

The incident was disclosed last week, but news of the potential ID photo leak came to light on Wednesday. A representative from the UK’s Information Commissioner’s Office, which oversees data breaches, stated: “We have received a report from Discord and are assessing the information provided.”

The images in question were submitted by users appealing age-related bans via Discord’s customer service contractors, which is a platform that allows users to communicate through text, voice, and video chat for over a decade.


Some nations, including the UK, mandate age verification for social media and messaging services to protect children. This measure has been in effect in the UK since July under the Online Safety Act. Cybersecurity professionals have cautioned about the potential vulnerability of age verification providers, which may require sensitive government-issued IDs, to hackers aware of the troves of sensitive information.

Discord released a statement acknowledging: “We have recently been made aware of an incident wherein an unauthorized individual accessed one of Discord’s third-party customer service providers. This individual obtained information from a limited number of users who reached out to Discord through our customer support and trust and safety teams… We have identified around 70,000 users with affected accounts globally whose government ID photos might have been disclosed. Our vendors utilized those photos for evaluating age-related appeals.”

Discord requires users seeking to validate their age to upload a photo of their ID along with their Discord username to return to the platform.

Nathan Webb, a principal consultant at the British digital security firm Acumen Cyber, remarked that the breach is “very concerning.”

“Even if age verification is outsourced, organizations must still ensure the proper handling of that data,” he emphasized. “It is crucial for companies to understand that delegating certain functions does not relieve them of their obligation to uphold data protection and security standards.”

The Surprising Benefits of Some Ultra-Processed Foods

Ultra-processed foods (UPFs) have been labeled as “poison,” “addictive,” and “junk,” sparking justified concerns due to their links with various health issues, including obesity, type 2 diabetes, anxiety, and depression.

Their rapid rise has transformed the food landscape so drastically that what we consume today would be unrecognizable to even recent generations. From an evolutionary perspective, our bodies certainly aren’t equipped to handle them.

It’s no surprise that UPFs are a primary focus in efforts to tackle diet-related chronic diseases in the UK and US. However, we believe that the prevailing panic surrounding UPFs needs to be replaced with more thoughtful discussions. Not all ultra-processed items, like flavored yogurt or whole grain bread, deserve the same cautionary approach as sweets or sugary cereals. Being ultra-processed doesn’t inherently equate to being unhealthy; our perspective should be informed by previous scientific research.

As people consume more UPFs, their intake of saturated fat, sodium, and sugar tends to rise, while their intake of fiber, protein, and vital micronutrients declines. This trend runs counter to a healthy diet. Kevin’s recent research indicates that UPFs are often overeaten when they are energy-dense (more calories per bite) or particularly palatable (often combining nutrients such as sugars and fats that rarely coexist in nature).

On the other hand, Kevin’s research demonstrates that consuming UPF-rich meals that are energy-dense but less palatable can prevent weight gain. In fact, you could potentially lose weight even without intending to follow such a diet.

These insights hold significant implications, not only for individual choices but also for nutrition policies and regulations. Instead of broadly targeting all UPFs, efforts should concentrate on those that don’t meet healthy food standards. The U.S. Food and Drug Administration (FDA) is already heading in this direction, having recently introduced a definition of “healthy” food. This approach mirrors the UK’s nutritional profiling system, which emphasizes increasing the consumption of ingredients like fruits, vegetables, and whole grains while restricting sugar, sodium, and saturated fat. By honing in on UPFs with high-calorie or palatability-inducing combinations of nutrients, we can better tackle products that significantly contribute to obesity and related health concerns.

Addressing these specific foods requires implementing public health policies akin to those used in reducing tobacco usage, such as marketing limitations, compulsory labeling, and robust taxation. Furthermore, we must promote policies that improve the convenience, affordability, and accessibility of healthy foods, while also encouraging companies to reformulate UPFs to be healthier. For instance, envision a pizza made with a frozen whole-wheat crust topped with vegetables.

Some UPFs already align with FDA standards for healthy foods (such as whole grain bread and yogurt), and these items are today free from such regulations. Many people rely on UPF pasta sauces, hummus, frozen meals, canned beans, and bread, which can easily fit into a healthy diet. Therefore, it is crucial to pinpoint which UPFs pose the greatest risk.

While UPFs are not going away anytime soon, their narrative is still evolving. Let’s move past the fear and toward informed coexistence by recognizing how certain UPFs can be detrimental and taking appropriate action.

How a Far-Fetched Conspiracy Diverts Attention from the Real Threat of Climate Change

“Everyone knows that airplanes negatively impact the climate…”

Oversnap/Getty Images

Years ago, I attended a climate science conference at University College London. While the specifics of the meeting are lost to me, the day remains vivid. Upon arrival, I encountered demonstrators outside, a familiar sight at such events that typically draw both supporters and skeptics of climate change.

Initially, the protesters conducted themselves peacefully, and I chose to enter the conference. Around mid-morning, however, they disrupted the lecture hall, heckling the speaker before storming the stage with their slogans and signs.

The protesters were unlike any I had encountered. Instead of being traditional climate activists or skeptics, one was a proponent of a conspiracy theory called chemtrails. In essence, this theory posits that the condensation trails (contrails) left by aircraft contain harmful substances deliberately released to manipulate the weather, poison people, or serve other sinister purposes.

This is untrue. Contrails are simply long streaks of ice crystals created when water vapor in engine exhaust freezes in the cold air at cruising altitudes. While they typically dissipate quickly, under certain conditions they can linger for hours, forming what conspiracy theorists label as chemtrails.

Like many conspiracy theories, this one carries elements of truth. Although contrails may look stunning against a summer sky, they nevertheless contribute to environmental damage.

It’s well-established that airplanes have an adverse effect on the climate. Burning aviation fuel represents about 2.5% of global greenhouse gas emissions. Yet, contrails and contrail-induced clouds are categorized as “aeronautical non-carbon dioxide.” The climatic effects might be equally or even more severe.

This is attributable to basic physics. Similar to greenhouse gases, ice crystals in cirrus clouds trap infrared radiation escaping from Earth, generating a warming effect. They also reflect incoming sunlight, counteracting this effect. Ultimately, though, they contribute to global warming.

In reality, the impact of contrails on climate is not completely understood. Last year, NASA acknowledged this knowledge gap and asked the National Academies of Sciences, Engineering, and Medicine to investigate the climatic repercussions of contrails and suggest research methodologies.


Contrails may look eerily beautiful on a summer evening, but they are quietly harming the environment.

Recently published, the report states that contrails might contribute to warming potentially exceeding that of aviation fuel, though significant uncertainty remains. Fortunately, options exist to mitigate this impact, including altering fuel formulations, refining engine designs, and rerouting flights to avoid areas conducive to contrail formation.

The report does not mention chemtrails, which is sensible. While the panel might have considered debunking this unfounded conspiracy theory, they opted not to give it publicity. Regardless, the report is unlikely to effect change, especially under the current US administration. Donald Trump’s administration has shown a tendency towards anti-science and conspiracy-driven climate skepticism, making addressing contrails a low priority. Significant regulatory changes regarding the airline and fossil fuel industries are necessary, so don’t expect immediate action.

I suspect that the airline and fossil fuel sectors silently welcome chemtrail theorists; their distractions divert attention from the true implications of contrails on climate.

Instead, the report will likely collect dust, while another report on chemtrails gets commissioned. Reports associate President Trump’s Secretary of Health and Human Services, Robert F. Kennedy Jr., with the conspiracy as part of an unscientific initiative to make America healthy again. Despite the absence of credible evidence, the notion persists.

Earlier this year, while enjoying a sunny afternoon, I had a conversation with my neighbors. “Have a nice day,” I said. “If they weren’t here, they will be,” he replied, gesturing skyward at intersecting contrails. He, too, is a climate change skeptic.

The chemtrail conspiracy is inherently frustrating—wholly futile. Despite their lack of scientific understanding, conspiracy theorists seem to think their beliefs will yield results. They are intrinsically distrustful of corporate and governmental authority and care about both environmental and human welfare. Yet, their actions only draw attention away from genuine protests and misallocate it toward unfounded notions.

The UCL meeting ultimately succumbed to continuous protests. If the dissenters believed they had triumphed, they were mistaken. Climate change remains a grave threat—chemtrails do not exist.

U.S. Regulators Launch Investigation into Tesla’s Self-Driving System Following Multiple Crashes

U.S. automotive safety authorities have initiated an investigation into Tesla vehicles equipped with fully autonomous driving technology due to traffic safety infractions following multiple accidents.

The National Highway Traffic Safety Administration (NHTSA) stated that the electric vehicle manufacturer’s automated driving assistance system, which necessitates driver attention and intervention when required, “caused vehicle actions that contravened traffic safety regulations.”


NHTSA’s preliminary evaluation marks the initial step that could lead to a vehicle recall if deemed a safety risk.

The agency reported incidents of 2.88-metre Teslas disobeying red lights and traveling against oncoming traffic while changing lanes while utilizing the system.

NHTSA indicated that there were six reports of Tesla vehicles in fully autonomous driving (FSD) mode “entering intersections on red, proceeding into intersections against red lights, and subsequently colliding with other vehicles within those intersections.”

The agency highlighted that at least one individual sustained injuries in four of the crashes. Tesla has not yet responded to Reuters’ request for comments.

NHTSA documented 18 complaints and a media report stating that Tesla vehicles operating in FSD mode “failed to adhere to red lights, did not come to a complete stop, or inadequately detected and displayed the appropriate signal conditions on the vehicle interface.”

Some whistleblowers expressed that the FSD “failed to provide any alerts regarding the system’s operation when approaching a red light.”

Tesla’s FSD is more sophisticated than the Autopilot system and has been under NHTSA scrutiny for a year.

In October 2024, authorities initiated an investigation into 2.4 million Tesla vehicles equipped with FSD following four accidents under poor visibility conditions, such as sun glare, fog, or airborne dust. One incident in 2023 resulted in a fatality.

According to Tesla’s website, FSD is “designed for fully attentive drivers who maintain their hands on the wheel and are prepared to assume control at any moment. These features are meant to grow more capable over time, but the features currently enabled do not render the vehicle self-driving.”

Richard III’s Oral Microbiome Indicates Severe Periodontal Disease

The oral microbiome extracted from King Richard III, derived from analysis of his dental plaque, indicates he may have suffered from a condition that could lead to jaw deterioration.

In 2012, the skeletal remains of Richard III were found beneath a parking lot at the former Greyfriars Church in Leicester, England. Initially thought to be Richard III—who was killed in the Battle of Bosworth Field in 1485 and interred in Leicester—dental and skeletal evidence, including a head wound and spinal curvature, correlated with descriptions from his death. Subsequent genetic tests confirmed the identity of the remains.

Although Richard’s reign only lasted two years amid the Wars of the Roses, he significantly impacted English history, with allegations of plotting against his nephews while they were imprisoned in the Tower of London, alongside William Shakespeare’s portrayal of him as a malevolent figure in his famous play.

Nevertheless, details of Richard’s daily existence are scarce. To uncover more, Turi King and fellow researchers at the University of Bath, UK, collected samples of tartar—hardened dental plaque—from three of his well-preserved teeth.

Dental plaque is effectively a time capsule, retaining DNA from microorganisms and remnants of food. “The quantity of DNA obtained from Richard III’s tartar is among the highest recorded in archaeological contexts,” the researchers stated, noting the detection of over 400 million DNA sequences.

“No one has previously sequenced 400 million ancient DNA fragments; it’s an astonishing figure,” remarks Laura Weyrich from Pennsylvania State University. “This indicates that our capabilities with ancient DNA are likely more extensive than previously thought.”

Dr. King and his team identified almost 400 microbial species from the DNA, comparable in variety to samples from well-preserved dental tartar across Britain, Ireland, Germany, and the Netherlands over the last 7,000 years, spanning from the Neolithic to modern times. “It suggests that elite populations shared microbial strains akin to those of the broader populace, despite their affluent lifestyles and experiences,” Weyrich notes.

However, the research team could not collect adequate plant or animal DNA to determine Richard’s dietary habits. Nevertheless, previous studies on his bones from his last two years indicated he drank non-local wine and consumed large quantities of game, fish, and birds, including swans and herons.

Professor Weyrich indicated that results regarding the microbiome could vary if the team obtained samples from more than one tooth and compared them to similar teeth from groups in Germany or the Netherlands. She also mentioned that their limited sampling does not provide a comprehensive view of Richard’s oral microbiome, as distinct bacteria inhabit different areas of the mouth and different surfaces of the teeth.

The king’s well-preserved teeth may provide insights into his oral microbiome.

One particularly prevalent bacterium identified is Tannerella forsythia, which is linked to periodontal disease, a serious gum infection that can lead to bone loss around the teeth. Given the poor oral hygiene of the 15th century, Richard had a cavity when he died at age 32, though this does not automatically indicate he had periodontal disease.

“Many individuals may harbor potentially harmful bacteria without becoming ill, while others could become infected,” explains Pierre Stollforth from the Leibniz Institute for Natural Products Research and Infection Biology in Germany. Weyrich adds that examining bone loss in the jaw could reveal if Richard suffered from periodontal disease.

“I’m particularly passionate about bridging social science, history, and genetics,” Stallforth states. “Having access to the dental tartar of historical figures is extraordinary as it enables us to gain deeper insights into their lives.”

Top 250 Oil and Gas Companies Hold Just 1.5% of Global Renewable Electricity Ownership

SEI 269586650

Oil corporations are making minimal investments in wind energy.

Associated Press/Alamy

Significant oil and gas firms hold under 1.5 percent of the global renewable electricity capacity, raising concerns about their dedication to green energy transition, despite their public assertions.

Marcel Llabero Pasquina and Antonio Bontempi, researchers from the Autonomous University of Barcelona, analyzed ownership data of over 53,000 renewable energy projects—including wind, solar, hydroelectric, and geothermal—tracked by the NGO Global Energy Monitor. They compiled this information to determine the proportion of these projects owned by the 250 largest oil and gas companies, which together dominate 88% of global hydrocarbon production.

As the world shifts away from fossil fuels, many chief energy companies have committed to investing in renewables, yet findings indicated that these top firms own merely 1.42% of operational renewable energy capacity worldwide. Notably, more than half (around 54%) of this capacity was acquired rather than developed by these companies. Their analysis of total energy output showed that just 0.13% of energy produced by these companies comes from renewable electricity.

“The findings were astonishing even to me,” remarks Llabero-Pasquina. “We understood they played a limited role in the energy transition. We thought it was merely for appearances. Yet, the numbers are even lower than we anticipated.”

Llavero Pasquina and Bontempi are associated with Environmental Justice, a collective dedicated to researching and advancing the global environmental justice movement. Llabero-Pasquina believes that the campaign’s stance bolsters his research. “It is crucial for us to maintain high rigor in our work so that we can effectively persuade others and demonstrate the truth.”

It is not surprising that major energy corporations, renowned for their oil and gas ventures, do not hold substantial stakes in renewable energy, says Thierry Bros from the Institute of Sciences in Paris. “Ultimately, [the energy transition] must be disruptive and not play into the hands of these companies.”

However, Bros argues that big energy firms are misleadingly portraying their efforts towards energy transition. “They represent themselves as incorporating methods like carbon capture for emissions from fossil fuels. Yet, I believe their actual engagement leans more towards carbon capture and sequestration, which may extend beyond their genuine expertise,” he states.

Offshore Energies UK, representing the UK’s offshore energy sector, including oil, gas, wind, carbon capture, and hydrogen, refrained from commenting directly on these findings. Nevertheless, it highlighted a previous statement from CEO David Whitehouse: “Rather than being in conflict, oil and gas, wind, and emerging low-carbon technologies form a unified system. The expertise of our workforce, the same individuals who developed the North Sea, is instrumental for achieving this transition,” he remarked.

Bird Flu Cases Surge Rapidly Despite Summer Season

The summer was notably calm regarding bird flu. There was a slight decrease in egg prices, a reduction in the number of poultry flocks being culled, and authorities remained hopeful.

“It was remarkable,” mentioned Shauna Voss, the deputy director of the Minnesota Animal Health Commission.

However, this tranquility didn’t continue.

As wild waterfowl, including geese, ducks, and cranes, commenced their seasonal migration, avian influenza has begun to spread once more. The migrating birds interact in lakes and ponds, facilitating the exchange of viruses.

In the poultry sector, avian influenza cases are rising more rapidly than anticipated. In states like Minnesota and Iowa, over 4 million birds have been culled in the past month after tests confirmed the presence of the H5N1 virus within their flocks. This increase coincides with a notable rise in infections observed in wild birds in northern regions.

State officials are preparing for a challenging fall, a season known for escalating case numbers.

“We confirmed our first positive case last week,” stated Iowa Secretary of Agriculture Mike Naig. This incident originated from a turkey farm in Calhoun County. “The real concern is how widespread this will become and what the fall season holds for us.”

Naig noted it’s still early to determine the outbreak’s impact on egg prices.

“The most honest answer is that we will have to wait and see. I wish I could provide more clarity,” Naig added.

This marks the fourth consecutive fall with rising bird flu infections, suggesting the virus is becoming endemic among wild birds and could continually threaten poultry.

“It’s not disappearing. It appears to be quite established,” Voss remarked.

The further the virus spreads, the higher the risk of it mutating to infect humans effectively. Some experts are concerned that budget cuts by the Trump administration on mRNA research could hinder scientists’ rapid development of new vaccines. Nevertheless, the current public health risk remains minimal.

As autumn progresses, authorities, wildlife specialists, and virologists are adopting a vigilant but patient stance.

“These times are intriguing,” noted Declan Schroeder, an associate professor of virology at the University of Minnesota College of Veterinary Medicine. “Everyone is watching closely to see the outcome.”


Avian influenza was initially spotted in U.S. commercial flocks in February 2022, following earlier outbreaks among wild birds. Nearly all infected poultry succumb, with over 175 million birds culled or killed by this summer. Two years ago, it was unexpectedly found that avian influenza had moved to dairy cows and was detected in unpasteurized raw milk, leading to significant changes in agricultural practices and milk testing.

At least 70 people have been infected, primarily farm workers who have close contact with birds and livestock. One fatality has occurred.

Researchers believe that wild birds spread the disease to poultry farms through multiple channels: direct contact, feed contamination, and workers inadvertently carrying the virus into barns. This makes the migration period a significant risk factor for outbreaks.

“If an infected bird migrates through a region and spreads the disease to others, our estimates indicate that the infection can spread rapidly,” explained Michael Ward, a professor focused on migration studies at the University of Illinois.

Ward added that the reduction of natural habitats is forcing birds to gather more closely, increasing the potential for the virus’s spread. In Illinois, wetland areas are declining due to drought conditions.

“This scenario is ideal for the virus to thrive,” Ward noted.

In response to inquiries regarding the uptick in avian influenza detections and the federal government’s course of action, the U.S. Department of Agriculture highlighted a five-pillar strategy announced in February, which allocates $100 million towards new biosecurity measures and vaccine development for poultry.

Countries like France are already vaccinating their poultry, but the Agriculture Department is still deliberating on whether the U.S. should follow suit. No vaccines have been approved yet, and their implementation could affect U.S. exports.

“While we believe an effective vaccination strategy would greatly help egg and turkey producers, we recognize the need for careful implementation to avoid negative impacts on other markets,” Naig explained. “The USDA is currently focused on this, and we are waiting to see what the vaccination strategy entails.”

Scientists have long expressed concerns that avian influenza viruses may eventually adapt to spread efficiently among humans. Although the risk remains low at present, Dr. Peter Chin-Hong, a professor of medicine at the University of California, San Francisco, specializing in infectious diseases, recommends that people take precautionary measures to prevent H5N1 and seasonal influenza infections.

“Get vaccinated against the flu. Avoid raw milk or unpasteurized cheese, especially during outbreaks. Don’t feed your cat outdoors during bird migration season,” Chin-Hong urges.

A scenario where humans contract both H5N1 and seasonal influenza simultaneously could pose challenges, as the avian influenza virus might easily mutate its genetic structure to adapt to humans.

The CDC halted H5N1 coordination meetings with healthcare providers earlier this spring. Chin-Hong is critical of this move, advocating for the agency to resume communications and opposing the administration’s decision to reduce funding for mRNA vaccine research. Biotechnology firm Moderna was in the process of creating an avian influenza vaccine utilizing an mRNA platform, but the Health and Human Services Department withdrew its grant.

The CDC has not responded to inquiries for comment.

Echoes of Rock: A Personal Exploration of Earth’s Geological History

The rocks lining Britain’s Jurassic Coast are roughly 185 million years old

James Osmond/Alamy

Whispers of Rock
Anjana Khatwa, Bridge Street Press (UK). Basic Books (USA, releasing November 4th)

Stones are often overlooked. How frequently do we consider the materials beneath our feet, or the origins of the beach pebbles we idly collect?

And how often do we recognize the role of geology when discussing nature and our pressing discussions about climate change? Any efforts towards addressing climate change and the future of our planet must include our relationship with the elements that constitute our world.

We are fortunate to gain insights from geoscientist Anjana Khatwa through her latest book, Whispers of Rock: Stories from Earth. This work, described as “an exhilarating journey through deep time,” is a heartfelt tribute that is sure to resonate with readers. Khatwa has dedicated a significant part of her life to promoting an understanding of geology, providing the scientific detail that highlights her profound knowledge.

In this book, she methodically covers topics such as the formation of mountains, craters, and slate, interspersing fascinating anecdotes. For instance, the iconic Taj Mahal of India, a symbol of love, was constructed from ivory-white Makrana marble that dates back approximately 2 billion years, originating from ancient landmass collisions. This complex genesis involved tectonic shifts, cyanobacteria, photosynthesis, and calcium carbonate, all coming together to create the stones used in this magnificent structure.

Once the scientific framework is laid down, Khatwa breathes life into the narrative of rocks and minerals, transforming it into a sensory experience far removed from the geology classes of my past. She invites readers to appreciate the negative spaces carved in Petra, Jordan, which form breathtaking structures and the unexpected beauty found within. She describes the markings on the stone as remnants of an ancient river, illustrating her deep connection to these geological marvels, becoming a “keeper of the stories of time.”


A recipe that involved tectonic movements, photosynthesis, and more resulted in the marble utilized in the Taj Mahal.

Khatwa’s passion for stones began in her childhood, walking on solidified lava flows in southeastern Kenya. Throughout her book, she takes readers on a global journey, including her hometown of Dorset, England, where she enjoyed 20 years of geological history at the Jurassic Coast World Heritage Site.

This adventure reveals how rocks have shaped her life and the lives of many others. We explore the colossal sarsen stones of Stonehenge in England, delve into the science and folklore of New Zealand’s Ponamu greenstone, and trace the socio-political history of the Black Belt, a fertile region in the American South shaped by cotton plantations after the removal of indigenous communities.

However, what truly distinguishes this book is Khatwa’s personal narrative. She openly addresses the lack of diversity in the environmental sector in the UK and shares her experiences as a mother, imparting a sense of vulnerability along the journey.

She reflects on how she was “transformed by the whiteness of my working environment” and came to realize that her cultural and spiritual identity often took a backseat to her scientific persona. This book is essential reading for anyone grappling with that duality or wishing to understand it better. We stand with Khatwa as she navigates the space between belonging and the feeling of being an outsider.

Whispers of Rock is packed with such insight that it requires contemplation after each chapter. Khatwa is also intentionally provocative, acknowledging that the intersection between science and spirituality may make some readers uncomfortable, as it challenges their preconceived notions. Yet, this provocative approach sparks a genuinely enlightening exploration.
