Even if atmospheric carbon dioxide returns to pre-industrial levels and the global temperature decreases, the Arctic is projected to warm by approximately 1.5 degrees Celsius.

It is also expected that the region will receive about 0.1 millimeter of extra precipitation daily, regardless of the implementation of large-scale carbon dioxide removal (CDR) strategies.

“These findings emphasize the irreversible aspect of climate change in the Arctic, even with aggressive CDR efforts,” the researchers stated in their publication.

Current atmospheric CO2 levels are roughly 1.5 times greater than pre-industrial levels, resulting in a warming of 3°C or more. A study published in March revealed that even if extra carbon dioxide were removed, sea ice coverage would still average 1 million square kilometers less.

In a new investigation, researchers led by Xiaodong from the Institute of Atmospheric Physics in Beijing utilized 11 distinct climate models to assess the likelihood of continued Arctic warming. The findings also indicate that precipitation is likely to increase, according to Michael Meredith from the British Antarctic Survey, who was not part of the study.

The primary reason for this persistent warming is that oceans, which have absorbed 90% of the heat from global warming, will continue to warm the Arctic for centuries, even when atmospheric temperatures decrease. This situation will likely be amplified by feedback mechanisms, such as diminishing sea ice, which causes the open ocean to raise air temperatures.

“Even if the atmosphere continues to cool, the oceans will lag behind and counteract this trend,” Meredith remarked.

Many experts express skepticism about whether CDR methods, including tree planting and mechanical CO2 extraction, can significantly lower atmospheric CO2 levels due to the financial and energy challenges, a process that could take thousands of years.

Dong et al. examined a theoretical scenario where atmospheric CO2 levels quadrupled from pre-industrial amounts over 140 years, decreased for another 140 years, and then remained at pre-industrial levels for 60 additional years.

The study also reviewed two potential real-world climate scenarios: one in which humanity immediately reduces emissions, and another where emissions remain high but CDR efforts ramp up quickly starting in 2070. In these scenarios, similar to the theoretical model, the Arctic was found to be approximately 1.5 degrees Celsius warmer with precipitation increasing by an additional 0.1 mm per day by 2100.

The models forecast a decrease in temperatures and precipitation in the waters just south of Greenland and Iceland, contrasting with other regions in the Far North. This suggests a decline in the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for transporting warm surface water from the tropics to this area. This current is already weakening as global ocean temperatures rise, a trend that might lead to colder winters in Europe over time.

Climate-related effects, such as thawing permafrost and melting of the Greenland ice sheet, are likely to persist but were not included in this study’s models.

“The Greenland ice sheet is expected to behave as observed, meaning it will continue to lose mass and contribute to sea level rise,” stated Mark Selles from the US National Snow and Ice Data Center.

While the study indicates that the Arctic will remain warm for centuries, it is anticipated that it will eventually cool over the course of many more centuries or even millennia.

In today’s world, our existence is intertwined with the digital realm. From finance to culture, news to gossip, everything thrives online. The rise of Generated Artificial Intelligence is a significant narrative, yet can you identify its physical origins? The tangible world seems absent.

Nevertheless, we inhabit a material world. Our infrastructure is dependent on materials like steel, lithium, and cobalt, all essential for powering vehicles. Though these materials may lack allure, they significantly influence our lifestyle and global events.

We could soon witness a transformative breakthrough: a revolutionary perspective on materials. History has shown us that the potential outcomes are monumental. Back in the late 1920s, groundbreaking advancements in materials science unveiled how electrons fill specific energy levels and the gaps between them, paving the path for transistors, the fundamental building blocks of modern computer hardware, including the chips that drive AI.

Research has long suggested that materials possess more than just straightforward energy bands. They may also contain intricate, undulating quantum topographies that dictate their properties. This quantum landscape is now visualized for the first time, as indicated in the cover article (see “Glimpse of a Secret Quantum Landscape in All Issues”).


Materials may have subtle, undulating quantum topography

This profound exploration could lead to breakthroughs as significant as the advent of transistors. For instance, one of my aspirations is discovering a material that can conduct electricity without resistance at room temperature.

Identifying such superconductors could minimize electricity loss, yielding tremendous advantages for green energy and mitigating climate change, among others.

Furthermore, this research may unveil entirely new types of materials that we have yet to envision. Rather than distancing ourselves from the material world, we might be on the verge of broadening our understanding.

Major Health Implications for 97% of Autistic Adults Over 60 Who Remain Undiagnosed

A major new review indicates that elderly individuals are significantly less likely to receive an autism diagnosis.

The survey estimates that around 89% of individuals with autism aged between 40 and 59 have never been diagnosed. This figure rises to 97% for those over 60.

Our analysis compiled various studies on how autism impacts individuals later in life. The findings revealed that older autistic individuals face a high prevalence of both physical and mental health challenges, are less likely to have been adopted, and generally report poorer health.

Seniors on the autism spectrum encounter difficulties in accessing healthcare and building strong relationships, both of which are closely tied to health outcomes.

While autism is thought to affect roughly 1 in 100 people, the recorded diagnoses drastically drop for individuals over the age of 40.

This review highlighted U.S. data showing that autistic individuals experience higher rates of nearly all physical ailments compared to their non-autistic counterparts, including cardiovascular issues, immune disorders, and gastrointestinal problems. Furthermore, over half of older individuals with autism reported having at least one psychiatric issue, such as anxiety or depression.

“People with pronounced autistic traits, despite lacking a formal diagnosis, experience similar challenges,” stated Dr. Gavin Stewart, who led the King’s College London review.

“Being autistic yet undiagnosed can carry significant implications. Access to necessary support systems becomes limited for many undiagnosed autistic individuals, preventing them from addressing mental health concerns,” he explained to BBC Science Focus.

This lack of support complicates the ability of individuals with autism to navigate medical systems. Characteristics such as diverse communication styles, sensory sensitivities, and specific daily needs can make interactions with modern healthcare environments challenging.

For instance, autistic individuals may struggle to convey their symptoms to a non-autistic physician, particularly when overwhelmed by the sensory input of a noisy, brightly lit waiting area.

An enhanced sense means that some autistic individuals find busy and noisy environments challenging.

“Many autistic individuals express that it’s challenging to exist in a world that doesn’t accommodate their needs,” Stewart noted.

The challenge of forming relationships also contributes to greater social isolation among people with autism, leaving them without necessary support networks as they age.

“While many autistic individuals are socially motivated and cultivate fulfilling relationships, societal expectations can create obstacles that lead to their alienation,” Stewart added.

This study aims to highlight the lack of research on adults with autism, noting that a mere 0.4% of studies have focused on the condition in older populations.

“Rates of underdiagnosis are alarmingly high among older adults. Much of our research systematically overlooks a significant portion of the autistic population, resulting in a knowledge gap regarding how autistic individuals age and a deficiency in relevant policies and services,” Stewart commented.

“This oversight stems from the fact that many older autistic individuals today were likely missed due to the narrow diagnostic criteria used in their youth.”

Most autism diagnoses occur in childhood, yet the condition has only been recognized in diagnostic manuals since the 1960s.

“Since then, the criteria have shifted from a rare condition defined by narrow standards to a broader, more inclusive framework,” remarked Stewart.

Moreover, older autistic individuals are more prone to misdiagnosis; a 2019 study found that one-quarter of adults with autism were initially diagnosed with mental health disorders such as anxiety or personality issues before their autism was recognized.

Increasing awareness among educators, healthcare providers, and the general public has led to more individuals identifying autism symptoms in both children and adults.

The US is Experiencing More Frequent Extreme Weather Events, Yet Attitudes and Actions Remain Unchanged

In the wake of a deadly flood in central Texas in 1987, some demonstrated their resilience against the fury of Mother Nature. This month’s devastating flash floods inundated the area with an astonishing volume of rain in a matter of hours, resulting in over 100 fatalities.

Prior to 2021, the typically temperate regions of the Pacific Northwest and Canada faced a Killer Heat Wave, but they were not exempt. Tropical Hawaii, once distant from drought-induced wildfires, faced its own challenges. That changed. Moreover, many inland communities in North Carolina considered hurricanes a coastal dilemma until the remnants of Helen roared in unexpectedly last year.

According to climate scientists, climate change is driving an increase in both the frequency and intensity of extreme weather events. Government data supports this evidence. Nonetheless, both people and governments tend to overlook this reality, clinging to outdated notions and failing to prepare for a concerning future, a meteorology expert pointed out to The Associated Press.

“With climate change, what was once considered extreme is now the average, and events that were once rare within decades are becoming new extremes,” stated Michael Oppenheimer, a climate scientist at Princeton University. “We are now experiencing phenomena that were virtually unprecedented.”

According to the National Oceanic and Atmospheric Administration, summer averages show that Extreme Climate Indicators are tracking hurricanes, heavy rainfall, droughts, and temperature fluctuations that are 58% higher than those recorded in the 1980s.

Despite the alarming trends, society is failing to respond adequately, Oppenheimer remarked.

“There’s ample evidence that we’re complacent, yet these risks are approaching us like an oncoming freight train, and we are just standing on the tracks, unaware,” he explained.

Shifting Public Perception

While climate change is a paramount issue, experts warn that our responses and tendency to disregard changes may exacerbate the situation.

Marshall Shepherd, a meteorology professor at the University of Georgia and former president of the American Meteorological Society, stated that people’s decisions are often influenced by their experiences during prior extreme weather incidents, even those that did not directly affect them. This induces unwarranted optimism, as they assume that conditions will remain manageable despite increasingly severe storms.

He referred to the flooding events in Texas as a prime example.

“This area is known as flash flood alley. Flooding is a common occurrence here. … I often hear overly optimistic statements from locals.”

Even those in regions not typically prone to disasters must rethink their perspectives on calamities, advised Kim Klockow McClain, a social scientist focused on extreme weather at the University Corporation for Atmospheric Research, which specializes in disaster warnings and risk communication.

Her advice is straightforward: If you’re accustomed to minor flooding, you should take note of events like those in Texas and recognize that conditions are changing.

Ignoring Reality Won’t Eliminate It

Following devastating storms and wildfires, individuals who have survived often believe such events won’t recur. This mindset can be a coping mechanism, yet the reality is that extreme weather occurrences are becoming more frequent and widespread, complicating effective preparedness.

According to Susan Cutter, co-director of the Hazards Vulnerability & Resilience Institute at the University of South Carolina:

Lori Peak, director of the University of Colorado’s Natural Disaster Center, indicates that surviving past extreme events can mislead people into thinking they are immune to future disasters. This kind of overconfidence can be hazardous. “Just because I survived fires, floods, hurricanes, or tornadoes does not guarantee that the next incident will mirror the last,” she cautioned.

What is Happening?

As weather patterns grow increasingly extreme, scientists observe that our capacities to adapt are lagging behind.

“Our vulnerability is heightened as our nation’s infrastructure ages, and more individuals are residing in potential danger zones,” Peak noted. “With population growth, more people live in perilous areas, particularly along the coast.”

The Trump administration’s funding cuts have threatened critical agencies responsible for climate research, disaster alerts, and responses—including the Federal Emergency Management Agency, the National Oceanic and Atmospheric Administration, and the U.S. Geological Survey Research Institute—further worsening the situation, according to several specialists.

Experts assert that knowledgeable and skilled personnel have already departed from these bodies, and it may take years to regain that expertise and skill set.

“We are dismantling the capabilities that will be increasingly necessary in the future,” Oppenheimer cautioned.

Peak emphasized the need for nations to anticipate and prepare for worst-case scenarios instead of merely reflecting on past events.

“This is our future,” Peak concluded. “We are clearly entering an era marked by escalating fires, floods, and heat waves.”

The miserable wolves remain extinct.

Romulus and Remus are genetically modified grey wolves

Giant Biology

A company called Colossal Biosciences says it has revived the extinct species, the miserable wolf. “On October 1, 2024, for the first time in human history, Colossal managed to restore the once-appropriate species through the science of annihilation. After more than 10,000 years of absence, our team is proud to return the miserable wolves to their rightful place in the ecosystem.” That is an allegation made on the website of the US-based company. This is what we know.

what happened?

Colossal claims that three GMO-modified grey wolf puppies (two men born in October, called Remus, and a woman born in January, called Khaleesi) are actually miserable wolves. The same company recently announced the creation of wool mice and almost complete tyrasin, or Tasmanian tiger genomes.

What is a miserable wolf?

The miserable wolf is a big extinct dog (Enocion dillus) It lived in the United States until about 10,000 years ago. The animal looked like a large wolf with a white coat. They became famous game of thrones TV series – therefore, the name Khaleesi is named after the main character of the show.

So, are the miserable wolves an extinct wolf species?

no. Although grey wolves and miserable wolves were thought to be very closely related based on physical similarities, 2021 study of ancient DNA They finally revealed that they shared a common ancestor about six million years ago. Jackals, wild African dogs, and dolls are all more closely related to grey wolvesCanis Lupus) Dire’s wolves despite their similar appearance.

Does that mean there are many genetic differences between grey wolves and miserable wolves?

Beth Shapiro of Colossal says her team will sequence the full genome of Dire Wolf and release it to the public soon. Shapiro didn’t know New Scientist There are several differences, but the two species said they share 99.5% of their DNA. The genome of the grey wolf is about 2.4 billion pairs long, leaving room for millions of base pair differences.

And does Colossal claim that by creating 20 gene edits, he transformed the grey wolf into a miserable wolf?

That’s the argument. In fact, five of these 20 changes are based on mutations known to produce light coats in grey wolves, Shapiro said. New Scientist. Only 15 are directly based on the tragic wolf genome, aimed at changing the size, muscle tissue and ear shape of animals. According to Shapiro, it is clear whether these changes had an intended effect on genetically modified animals.

So, aren’t these puppies really bad wolves?

It all comes down to how you define the seeds, says Shapiro. “The concept of species is a human classification system, where everyone can oppose it, and everyone can do it right,” she says. “Phylogenesis can be used [evolutionary relationships] Species concept To determine what you call a species, it’s what you imply… We use the concept of morphological species and say that if they look like this animal, they are animals. ”

What happens to a gene-edited grey wolf that looks like a terrible wolf?

Shapiro says it grows in an 800 hectares of reserve. “They can’t get the shard unless we know,” she says. There are no plans to allow them to breed.

AI avatars assist in legal appeals as judges remain serious

Jerome Dewald sat with his legs crossed, his hands folded in his lap before a New York judge’s appeal panel, ready to argue for a reversal of the lower court’s decision in a dispute with his former employer.

The court had allowed Mr Dewald, who represented himself, not his lawyer, to involve his arguments in a pre-recorded video presentation.

When the video began to play, it showed that a man younger than Dewald’s 74-year-old was standing in a blue-collar shirt and beige sweater, wearing a blue-collar shirt and a beige sweater, in front of what appeared to be a blurry virtual background.

Seconds after the video, one of the judges confused by the on-screen image asked Dewald if the man was his lawyer.

“I generated it,” replied Dewald. “It’s not a real person.”

Judge Sally Manzanette Daniel, the first Judicial Division of the Appellate Division, temporarily suspended. It was clear that she was unhappy with his answer.

“It’s good to know that when you created your application she snapped him.”

“I’m not grateful for being misunderstood,” she added before someone yells at me to turn off the video.

What Dewald didn’t disclose is that he created digital avatars using artificial intelligence software, the latest example of AI sneaking into the US legal system in a potentially troublesome way.

Dewald’s presentation hearingwas taken by a court system camera on March 26th and previously reported Associated Press.

Dewald, plaintiff in the case reached Friday, said he was overwhelmed by the embarrassment of the hearing. He then sent an apology letter to the judge soon after, expressing his deep regret and saying that he admitted that his actions “cautiously mislead” the court.

He said he relied on using the software after stumbling over his words in previous legal proceedings. He thought that using AI in his presentation might help ease the pressure he felt in court.

He said he had planned to create a digital version of himself, but did so he encountered “technical difficulties.”

“My intention was not to deceive, but to present my argument in the most efficient way possible,” he said in a letter to the judge. “But we recognize that appropriate disclosure and transparency must always be prioritized.”

Dewald, a self-proclaimed entrepreneur, had sued previous ruling in a contract dispute with his former employer. He eventually presented oral arguments at the appeals court, frequently pausing and frequently pausing to reorganize and read the statements he had prepared and prepared from his cell phone.

As embarrassing as he was, Dewald was able to provide some comfort to the fact that an actual lawyer got into trouble in using AI in court.

In 2023, New York State lawyers faced serious consequences after him I created a legal brief using CHATGPT Filled with false judicial opinions and legal quotations. The incident showed flaws relying on artificial intelligence and echoed through legal trade.

That same year, former President Trump’s lawyer and fixer Michael Cohen provided his lawyer with a fake legal quote he obtained from Google Bard, an artificial intelligence program. Cohen ultimately pleaded mercy from a federal judge who was the main side of his case, emphasizing that he had no idea that the generated text service could provide false information.

Some experts say artificial intelligence and large-scale language models can be useful for people who have legal problems to deal with but can’t afford a lawyer. Still, the risks of technology remain.

“They can still hallucinate. “We need to deal with that risk,” says Daniel Singh, assistant research director at the Law and Court Technology Center at William & Mary Law School.

Evidence of Alien Life on Mars: Ancient Beach Discoveries Remain Compelling

New research suggests that Mars once was the perfect holiday destination (if they were willing to overlook radiation exposure or lack of food sources), but also had the right conditions for alien life. why? The discovery of ancient sandy beaches on the red planet suggests that once a large liquid ocean spread across the north of the planet.

The research team behind the research from China and the US is This ancient coastline is the clearest evidence yet The Red Planet was previously habitable.

“Looking back at the places where the earliest life on Earth developed, it was in the interaction between the ocean and the land, which paints a picture of an ancient habitable environment that can embrace the conditions for microbial life,” he said. Benjamin Cardenasassistant professor of geology at Penn State University in the United States and co-author of the study.

Four billion years ago, these beaches would have been the best variety. The waves are softly wrapped sandy and immersed in the sun.

“We found evidence of a lack of wind, waves and sand. It’s a proper vacation style beach,” says Cardenas, whose research was published. Proceedings of the National Academy of Sciences (pnas).

To find this, researchers used a probe up to 80m (260 feet) below the Mars surface in a region of North Mars called the Utopian Plain, using radar imaging, using a probe up to 80m (260 feet) below the Mars surface.

We discovered 76 hidden structures at depths of 10-35m (33-115ft). Sadly, this turned out to be not a mysterious alien infrastructure (we can dream of it), but rather a sedimentary deposit similar to what is found around the Earth’s coastline.

3.6 billion years ago, the ocean may have covered almost half of the red planet. The Orange Star shows where China’s Roberzouron began its exploration. Meanwhile, the Yellow Star is where NASA’s patient rover landed. Both arrived on Mars in 2021. -Image credit: Robert Citron

The structure, thickness and length of Martian sediments showed that they were not formed by the melting of rivers, winds, lava or ice, but rather by stable ancient seas. In fact, they were roughly the same as 21 people on Earth, including the Bay of Bengal.

Specifically, a formation called “foreshore sediments” is formed by the tide and wind that descends the slope towards the ocean at a 15° angle and carries sediments like sand and gravel.

“This quickly stood out to us because it suggested there were waves, meaning there was a dynamic interface between air and water,” Cardenas said. This interaction, which also took place in the early history of the Earth, is important for the beginning of life.

The discovery suggests that Mars had a warm, humid climate for tens of millions of years.

“We tend to think of Mars as a static snapshot of the planet, but it was evolving. The rivers were flowing, the sediment was moving, the land was built and eroding,” Cardenas said.

“This type of sedimentary geology tells us how the landscape looks, how they evolved, and, importantly, helps us identify where we want to look for our past life.”

Scientists remain uncertain about the inhabitants of the massive sinkhole in Mexico

The deepest blue hole in the world, also known as an ocean sinkhole, can be found off the coast of Mexico’s Yucatan Peninsula. It plunges to a depth of at least 420 meters (1,378 feet), remaining unexplored by researchers.

Local divers discovered the lake, named “Ta’am Dja” or “Deep Sea” in Mayan, over two decades ago. In 2021, scientists attempted to measure its depth using an echo sounder, estimating it to be 275 meters (902 feet). However, a later expedition in 2023 employed a device called a conductivity, temperature, and depth (CTD) profiler, revealing a depth of 420 meters (1,378 feet) without reaching the bottom.

Blue holes are naturally formed vertical-walled caves on the ocean floor, typically found in coastal regions with soluble rock formations like limestone. These geological formations may reach only a few tens of meters in depth and could be interconnected with underwater cave systems.

Due to poor water circulation, blue holes lack oxygen in their depths, posing challenges for organisms. Some microorganisms thrive in these conditions by consuming sulfur-based compounds like hydrogen sulfide. Additionally, creatures such as foraminifera and nematodes have been discovered living in blue holes, prompting further exploration to unveil the mysteries of Ta’am Dja’s deep blue waters.

Sales of boxed video games decrease in UK while digital revenues remain steady

With music sales and streaming revenue reaching a record high of £2.4 billion, the UK video games market has experienced consistent growth over the years, despite a 4.4% decrease. The most significant decline was seen in boxed video game sales, which dropped by 35%.

Data from the Digital Entertainment and Retail Association (ERA) predicts that the UK video games market will reach £4.6 billion in 2024, making it the second-largest market after TV and film, which is valued at £5 billion.

The shift in consumer buying habits from physical games to digital downloads and in-game purchases is evident in the increasing popularity of games like Fortnite and Roblox. Currently, boxed games account for 27.7% of new game sales in the UK, according to ERA data.

According to an ERA spokesperson, several factors have contributed to the decline in physical sales, including the shift towards digital downloads, subscription access, the console cycle downturn, and the lack of new hit IPs in the market.


The decrease in physical sales also reflects a decline in brick-and-mortar video game retail, with Games being one of the last specialist video game retailers in the UK. The shift away from selling video games towards toys and other merchandise has left customers with limited options for buying boxed games in-store.

Global trends in the gaming industry indicate a decline in physical sales as digital distribution becomes more popular. While physical formats may still exist as collector items, digital distribution is expected to dominate the market in the future.

Download sales saw a slight decrease, while subscription revenue and mobile/tablet game revenue increased. Despite job losses and reduced investment, analysts anticipate a rebound in sales and profits in 2025 with new console releases and game titles.

Two NASA astronauts remain in space as testing of Boeing spacecraft continues

Their ambitious mission was initially planned for just one week, but now, after 56 days on the International Space Station, the two NASA astronauts remain in orbit, awaiting a safe return journey in the Boeing spacecraft.

The troubled Starliner capsule is facing issues with its propulsion system, including a leak in its helium and failure of five thrusters. Despite the leak being detected before launch, mission managers believed it wouldn’t impact the safety of the astronauts or the flight.

Over the weekend, NASA and Boeing engineers conducted a crucial “hot fire test” of the Starliner, which is set to carry veteran astronauts Sunita Williams and Butch Wilmore on its first crewed flight on June 5.

The test involved firing 27 of the capsule’s 28 jets in less than 1.2 seconds while evaluating their performance and checking for helium leaks. Preliminary results from the test were positive.

In a blog post published by NASA on Tuesday, it was stated that all thrusters performed well during the test.

NASA confirmed that the propulsion system of the Starliner remains stable, and the helium leak rate is not significant enough to endanger the return to Earth. The agency plans to recheck the system before the capsule separates from the space station.

A high-temperature burn test was also conducted with astronauts Wilmore and Williams inside the Starliner capsule as part of preparations for the return journey. The thrusters play a vital role in maneuvering the spacecraft during docking and undocking from the space station.

Overall, the progress made during the hot fire test is a positive sign for the upcoming crewed flight of the Starliner and the safe return of the astronauts.

Can the content on your iPhone remain private? | Technology

AI is a concern for Apple as it consumes a lot of power.

During its global developers conference, Apple unveiled its strategy to integrate AI into daily life, primarily focusing on the latest iPhone users.

Apple’s latest AI models are compatible with the iPhone 15 Pro and Pro Max, the only devices featuring the A17 processor. Additionally, Macs up to three years old with M1, 2, or 3 chips, as well as iPad Pros with similar internal hardware, can benefit from the upgrade.

The more affordable iPhone 15 models come with the A16 Bionic chip introduced in 2022 and 6GB of memory, compared to 8GB in the pricier Pro models. This difference is crucial because the M1 chip powering Macs is equivalent to the A14 processor in 2020 iPhones.

Numerous model numbers highlight that advanced AI features won’t function on just any phone, as many require high-performance devices. If Apple aims to deliver AI technology, it must do so through its data centers—an endeavor that poses challenges, as stated by Kari Paul:

At the core of Apple’s AI privacy measures is its new private cloud computing technology, where most of the computing is done in-house for Apple Intelligence features on devices. However, for tasks exceeding device capabilities, processing is outsourced to the cloud while safeguarding user data.

To uphold privacy, Apple only exports necessary data for each request, implements additional security measures at endpoints, avoids indefinite data storage, and offers tools and software related to its private cloud for third-party validation.

When it comes to AI queries, complete privacy—offered by online backup or messaging services—remains challenging due to server requirements for accurate responses. Apple has long stressed its commitment to privacy, setting itself apart from competitors like Facebook and Google with its “what happens on iPhone stays on iPhone” pledge.

Apple’s solution involves running user data-free data centers designed in-house to validate the integrity of the software. Security researchers are provided with tools to verify the software’s authenticity running on Apple’s servers.

Yet, the question remains: Can Apple be trusted? Huawei’s similar efforts failed to prove its independence from the Chinese government. Trust in Apple’s commitment to privacy is growing, but accommodating AI’s rise forces Apple to compromise its foundational principles.

While Apple emphasizes privacy, the implementation of AI features like Apple Intelligence may necessitate data transfer to ensure functionality, blurring the lines of privacy assurances.

Tesla sees largest revenue decline since 2012, yet stock prices remain on the rise

After the earnings release, Tesla stock plummeted by 10% in after-hours trading on Tuesday. This was despite missing Q1 2024 sales, having sharply lower profits, and recalling the recently launched $100,000 Cybertruck, which had seen a recent rise.

The electric vehicle maker’s revenue stood at $21.3 billion, slightly below expectations of $21.48 billion and down by 9% from a year ago, marking the largest decline since 2012. Profits were reported at $1.1 billion, a 55% drop from the first quarter of 2023, the company announced.

Despite the disappointing figures, the report also included upbeat news for investors. This included a preview of a ride-hailing app set to be integrated into Tesla products. The company revealed plans to bring new vehicle models to the market sooner than anticipated, citing the development of its robotaxi network.

Over the past three months, Tesla has doubled its AI computing capacity (smart software complexity) and invested $1 billion in AI infrastructure during the same period.


Thomas Monteiro, senior analyst at the company, mentioned that Tuesday’s report and Tesla’s plans to accelerate the development of more affordable vehicles helped alleviate some concerns among investors. “This announcement suggests that Elon [Musk] may refocus on the EV giant, which is positive news for shareholders,” he stated.

The earnings report was Tesla’s second since the launch of the Cybertruck, its long-awaited electric pickup truck. It was also the first report after the vehicle’s recent recall. The company faced challenges with the futuristic steel car, including a voluntary recall due to reports of a loose accelerator pedal potentially causing vehicles to become stuck when driving at full speed. Despite this, the company did not directly address the recall in its earnings release.

Even without the Cybertruck issues, Tesla has a tough year ahead as it announced a 10% reduction in its global workforce, affecting approximately 14,000 jobs. The company also slashed prices globally over the weekend. The entry of Chinese electric car manufacturers into the market has added to Tesla’s struggles in recent quarters.

Tesla reported a decrease in car deliveries for the first time in four years in the last quarter. The company warned that the growth rate in car sales could be considerably lower compared to 2023.

Addressing concerns about his workload, Elon Musk stated during the earnings conference, “Tesla consumes the majority of my work time. I work every day. I will ensure that Tesla prospers.”

The mysteries of the Moon may remain unsolved as new lunar missions approach

There is a new space race underway, with missions to the moon increasing at a significant pace. Recently, a spacecraft built by Intuitive Machines became the first U.S. mission to land on the moon since 1972’s Apollo mission.

China is preparing to launch Chang’e 6, furthering their lunar exploration program with plans to bring back lunar rocks from the far side of the moon. A NASA study suggests that 22 international missions could reach the moon by the end of 2026, potentially leading to astronauts leaving footprints on the moon once again.

Despite the exciting progress, researchers like Dr. Alanna Krolikowski and martin elvis warn of dangers overlooked in the rush of exploration. They emphasize the need to protect Sites of Extremely Scientific Significance (SESI) on the moon, similar to protecting special sites on Earth.


Krolikowski stresses the urgency of implementing SESI protections to avoid irreversible harm to these important areas. Two key locations on the moon, its backside shielded from Earth’s radio noise and its poles with valuable volatiles like water ice, require preservation for scientific research and exploration.

“The problem is urgent,” says Krolikowski. “We are facing a rapidly closing window in which SESI protections can be implemented to avoid the worst possible irreversible harm.”

Special attention is drawn to the moon’s poles with areas of eternal darkness that trap important volatiles. These regions hold valuable information about the history of the solar system, particularly in studying the early universe.

Researchers advocate for careful management of activities on the moon to avoid contaminating these special areas and preserving their natural state for exploration.

Proposals for protecting lunar SESIs include identifying and characterizing these areas, establishing rules in national and international space policies, and initiating negotiations under the United Nations for effective international cooperation.

Despite the challenges, experts like Krolikowski, Elvis, and Crawford stress the importance of getting it right to preserve the moon’s unique habitats and secrets. With increasing lunar activities, taking action now is crucial.

Black British entrepreneurs face challenges but remain resilient

Black founders in the UK are also seeing the effects of winter on their ventures.

According to one study, black founders in the UK have raised just 0.95% of all venture funding allocated in the country so far this year (or just $165 million out of about $17.3 billion). new report Written by Extend Ventures. 2023 would then be a year in the making, compared to 2022, when such founders raised 1.02% of all domestic venture investments ($316 million out of $30.88 billion), and 2022, when such founders raised 1.13% ($40 billion) of all domestic venture investments. This will be later than in 2021, when $454 million of the $30 million was allocated.

There has been a clear and consistent decline since 2020, when George Floyd was murdered, and global support and pressure to support Black communities has increased. The downward trend in the proportion of investments allocated to black founders is likely due to the venture recession of the past two years.

George Windsor, a data and research strategist who worked on the report, said black people make up 2.5% of the UK population and being properly represented in the venture ecosystem means they receive at least 2.5% of funding. will go to black-led businesses, he said.

Still, the achievement rate is 0.95% compared to 10 years ago, showing that progress is being made.

For example, just 0.28% of black UK founders raised venture funding in 2019, 0.23% in 2018 and 0.38% in 2017. According to Extend Ventures, between 2009 and 2019, only 38 Black founders were able to raise venture funding. In Japan. That number is now 80.

Even black women are doing better. Between 2009 and 2019, Extend discovered only the following: One Black women have raised more than $1 million in venture funding. Between 2019 and 2023, eight women did so.

Windsor said this progress is due to a myriad of factors, including “the growing awareness of racism, discrimination and inequality sparked by the Black Lives Matter movement and the killing of George Floyd.”

Extend co-founder Tom Adeyoola told TechCrunch that it also helps that there is less backlash against diversity, equity and inclusion efforts in the UK compared to the US.

“The UK values ​​slow and steady reform, rather than consequential, hollow, haphazard action. The desire for change here is deep-rooted and focused on systemic action. ” he said. “That said, if you look for anti-DEI rhetoric, you can find it in discussions and newspaper headlines about removing these roles from the civil service. I don’t know if it’s getting the public’s attention as we continue to highlight how much loss of growth is hurting the economy due to bias.”

The Extend report also found that although women of color still face challenges entering the industry, there has been a 100% increase in the rate of people from minority backgrounds becoming investors. It was also revealed that

Earlier this year, the UK Treasury Select Committee acknowledged the lack of investment in minorities and women in technology and looked at ways to increase investment.

Maintaining this momentum will require new initiatives and strengthening of existing ones, Adeyola said. “The data shows that it is very important to track cohorts and understand which companies receive funding beyond the early stages,” he said. “We need to make sure that appropriate measures are in place at the level of following companies.”
