SpaceX Successfully Launches Fake Satellite on Seventh Starship Test Flight

December 2024 Starship rocket preparing for seventh flight

space x

SpaceX's next Starship test flight will be its most ambitious yet, and for the first time will include a new “Block 2” version with a number of design updates.

What is a starship?

Starship is the most powerful rocket ever flown. SpaceX aims to develop the vehicle into a quickly reusable vehicle that can carry large payloads into orbit, land on Earth, and launch another mission within hours.

It's a bit confusing, but Starship is the name given to both the entire spaceship, which consists of a super heavy booster and the ship it launches, as well as a single ship once separated from the booster.

SpaceX is rapidly iterating on both Super Heavy and Starship, taking a Silicon Valley approach to design that considers regular testing and dramatic failures simply part of the process. However, this will be the first test of the so-called Block 2 Starship upper stage.

What's new in Starship Block 2?

the company says on the website Starship's electronics have been “completely redesigned” and now include more than 30 cameras. It also has 25% more propellant, is 3.1 meters taller, and has repositioned front flaps.

Also included for the first time is an early version of the pin needed to be captured and reused in ground towers. However, SpaceX currently only has one tower that is used to capture boosters, so there will be no attempt to capture Starships for reuse this time. A second tower is under construction.

What does a test flight involve?

SpaceX expects the upper stage to reach space, complete a partial orbit around Earth, safely re-enter the atmosphere, and fall in a controlled manner into the Indian Ocean. The Super Heavy's first stage must return to the launch site and be captured by the launch tower's mechazilla or “chopstick” arm. If successful, this will be the second capture.

The launch marks a milestone for SpaceX as it marks the first time Starship hardware will be reused. One of the Super Heavy's 33 Raptor engines was previously used on Starship's fifth test flight. This was the only test to date in which the booster was safely returned, so it was the company's first opportunity to reuse something.

Another first is Starship's deployment of 10 fake Starlink satellites. These mock satellites are comparable in size and weight to the company's upcoming third-generation Internet Beam hardware and will test Starship's ability to safely launch payloads into orbit. Previous Starship flights have never carried a payload. Toy bananas carried on Flight 6.

A number of other smaller tests will be performed during the seventh flight to provide engineers with valuable data. For example, one of the Starship's Raptor engines was scheduled to be reignited in space, and some heat-resistant tiles were removed as a test. Several types of new thermal tiles are also being tested, including those with active cooling capabilities.

When will the launch take place?

SpaceX has not officially announced a launch date, but the company's controversial owner Elon Musk said: Tweet points out the goal of January 10th.

According to several NOTAMs (Notifications to Airmen – Warning Pilots of Unusual or Potentially Hazardous Activities) issued by the US Federal Aviation Administration, the launch slot given to the company is mid-January 10th. It starts at 4pm standard time (10pm UK time).

The launch period runs until January 16, giving the company some leeway in the event the launch is postponed due to technical issues or bad weather.

Like all Starship launches, Flight 7 will lift off from SpaceX's property in Boca Chica, Texas, and will be streamed live online.

What happened on previous Starship launches?

During the first test flight on April 20, 2023, three of the 33 engines in the booster stage failed to ignite. The rocket then lost control and self-destructed.

During the second test flight on November 18, 2023, the flight progressed further, gaining enough altitude to separate the booster and upper stage as planned. The booster stage ultimately exploded before reaching the ground, and the upper stage self-destructed before reaching space.

Test Flight 3 on March 14, 2024 was at least partially successful as the upper stage reached space again, but it did not return to Earth unscathed.

The next flight was on June 6, when the upper stage reached an altitude of more than 200 kilometers and flew at speeds of more than 27,000 kilometers per hour. Both the booster and upper stage completed a soft landing at sea.

In Test Flight 5, the superheavy booster dropped onto the launch pad and landed safely on SpaceX's launch tower, known as Mekazilla, supported by “chopsticks.”

During Test Flight 6, Starship reached an altitude of 228 kilometers and splashed down in the Indian Ocean. Super Heavy aborted its landing on the launch tower due to a communications failure and instead made a controlled water landing in the Gulf of Mexico.

The New Rules for User Behavior on Meta Platform

MIta’s Rewritten policy on ‘hateful acts’ That means users will be able to say different kinds of things on that platform, Facebook, Instagram, and Threads. After Mark Zuckerberg announced sweeping changes to how content is monitored on the platform, multiple edits were made to the policy.

Among them are:

  • Certain injunctions against referring to transgender and non-binary people as “it” have been removed. A new section has been added to clarify that “mental illness or abnormality claims are permitted if based on gender or sexual orientation.” It said this was a reflection of “political and religious discourse around transgender and homosexuality, as well as the common use of non-serious terms such as ‘queer'”. Additionally, this policy is aimed at “those who seek exclusion, [using] Derogatory language in the context of discussing political or religious topics, such as when discussing transgender rights, immigration, or homosexuality. ”

  • Meta’s policy is to target individuals and groups based on their protected characteristics or immigration status with dehumanizing language that users compare to animals, pathogens, and sub-life forms such as cockroaches and locusts. There is no change in the fact that content should not be posted. However, this shift suggests that it is now possible to compare women to household goods and possessions, and to compare people to feces, filth, bacteria, viruses, diseases, and primitive humans.

  • Mehta removed warnings against avowed racism, homophobia, and Islamophobia. It also removed warnings against expressions of hate, such as calling people “shitholes,” “sluts,” and “bastards.”

Months of extreme weather in California lead to devastating wildfires

Palisades fire spreads through Los Angeles homes

Ethan Swope/Associated Press/Alamy

Fast-moving wildfires in the Los Angeles area are getting out of control long after California’s normal fire season ends. Powerful Santa Ana winds are not uncommon at this time of year, but these winds arrive after months of drought. This combination has sparked a series of devastating fires that could be an indication of how climate change is changing the way fires occur in the state.

“While the Santa Ana Fire is not new to Southern California, this type of explosive fire event has never occurred before in January and only once in December,” he said. crystal golden At the University of California, Merced.

As of January 8, there were at least four wildfires burning in the Los Angeles area. According to the California Department of Forestry and Fire Protection. The two largest fires were the Palisades Fire and the Eaton Fire, each burning more than 4,000 hectares (10,000 acres) in a single day. The fire has killed at least two people, destroyed at least 1,000 homes and forced tens of thousands to evacuate. The fire also threatens NASA’s Jet Propulsion Laboratory and the Getty Museum.

Strong winds in Santa Ana reached up to 129 kilometers per hour (80 mph), fanning the flames and spreading them rapidly. The storm is expected to be the most intense since 2011 and will be accompanied by “very dangerous fire weather conditions.” Forecast lasting until Jan. 8 afternoon, according to the National Weather Service. Fire weather could continue until January 10, making it difficult to extinguish the fire.

He said it was the latest in a “highly unlikely series of extreme climate and weather events” that had caused the intense fires. park williams at the University of California, Los Angeles (UCLA). Santa Ana is a feature of Southern California weather, but fall and winter rains typically limit fire impact. This year, such wet weather has not arrived yet, leaving the plants dry and on the verge of burning. In addition, a wet winter in 2023 encouraged growth, so there is more vegetation for fuel. Heatwaves and drought throughout 2024 have left the land arid.

The combination of large amounts of good fuel, drought and strong, hot, dry winds creates “the most explosive fire event imaginable,” Colden said.

Authorities are still investigating the cause of the fire. It will also take time to understand the role that climate change has played. But there’s reason to think it made the fire worse.

Above-average sea surface temperatures in the Pacific Ocean, likely due in part to climate change, are also contributing to the dry conditions. According to Daniel Swain At UCLA, these are High-pressure ocean ridges formed due to rising ocean temperatures That prevents wet weather carried by the jet stream from reaching Southern California.

This type of high-pressure weather has been occurring more frequently in the region over the past 50 years, which could be a sign of climate change, it said. Daniel Cairn at the University of California, San Diego.

The brain’s waste removal process disrupted by sleeping pills

During sleep, your brain eliminates toxins that have accumulated throughout the day.

Robert Reeder/Getty Images

Sleeping pills may help you doze off, but the sleep you get may not be as restorative. When mice were given zolpidem, which is commonly found in sleeping pills such as Ambien, their brains were unable to effectively remove waste products during sleep.

Sleep is important for removing waste from the brain. At night, a clear fluid called cerebrospinal fluid circulates around brain tissue and flushes out toxins through a series of thin tubes known as the glymphatic system. Think of it like a dishwasher, which turns on your brain while you sleep, says Miken Nedergaard at the University of Rochester Medical Center in New York. However, the mechanisms that push fluid through this network have not been well understood.

Nedergaard and his colleagues implanted optical fibers into the brains of seven mice. By irradiating chemicals in the brain, the fibers can track the flow of blood and cerebrospinal fluid during sleep.

They found that elevated levels of a molecule called norepinephrine cause blood vessels in the brain to constrict, reducing blood volume and allowing cerebrospinal fluid to flow into the brain. As norepinephrine levels decrease, blood vessels dilate and cerebrospinal fluid is pushed back. Thus, fluctuations in norepinephrine during non-rapid eye movement (NREM) sleep stimulate blood vessels to act like pumps in the glymphatic system, Nedergaard said.

This discovery reveals that norepinephrine plays an important role in clearing waste from the brain. Previous research has shown that when we sleep, the brain releases norepinephrine in a slow, oscillating pattern. These norepinephrine waves occur during NREM, a sleep stage important for memory, learning, and other cognitive functions.

Next, the researchers treated six mice with zolpidem, a sleeping pill commonly sold under the brand names Ambien and Zolpimist. The mice fell asleep faster than those treated with a placebo, but the flow of cerebrospinal fluid in the brain was reduced by about 30 percent on average. In other words, “their brains aren't being cleaned very well,” Nedergaard said.

Although zolpidem was tested in this experiment, almost all sleeping pills inhibit the production of norepinephrine. This suggests that they may interfere with the brain's ability to eliminate toxins.

It is too early to tell whether these results apply to humans. “Human sleep architecture is still quite different from mice, but they have the same brain circuits studied here,” he says. laura lewis at Massachusetts Institute of Technology. “Some of these basic mechanisms may apply to us as well.”

If sleeping pills interfere with the brain's ability to eliminate toxins during sleep, Nedergaard says, that means new sleeping pills must be developed. Otherwise, your sleep problems may worsen and your brain health may deteriorate in the process.

Ancient molluscs challenge our stereotypes: punk and emo fossils defy conventional perceptions

Digital model of an ancient mollusk punk ferox and emo swirl, Created from X-ray scans of fossils

Sutton et al. Nature (2025)

Two prehistoric marine mollusk fossils with distinctive spiky 'hairstyles' have been discovered and named. punk and Emotional.

Its strange appearance highlights the ancient diversity of molluscs, which today include creatures such as snails, slugs, clams, and octopuses.

“Some people may have a bit of a soft spot for molluscs. My partner called them loser animals, but they are one of the really important areas of life.” he says. mark sutton At Imperial College London.

He and his colleagues unearthed artifacts dating back 430 million years at a British site known as . herefordshire lagerstedt.

The fossil, from a group of molluscs known as Aculifera, was so delicate that researchers couldn't simply crack open the stone it contained.

Instead, Sutton and his colleagues use X-ray scans to identify structures inside rocks, slice the material thinly and photograph each layer, and combine the images to show what living things might look like. A 3D image was created. Both were earthworm-like animals with long spines about 2 centimeters long.

Sutton said the music-related nickname was originally a pet name. The name stuck and was officially proposed because the spike-laden fossil was reminiscent of the hairstyle of the punk rock movement. punk ferox and emo swirl.


“The spikes are probably primarily for protection,” Sutton said, but it's also possible that the spikes formed because the creatures needed to remove calcium buildup in their bodies while living in the ocean. be. In many cases, he says, such hard protrusions can serve both purposes.

Researchers don't quite understand how punk The specimen was moved, but the specimen emo It is preserved in a folded state, suggesting that it increments like a caterpillar. emo It also had many sturdy downward-pointing spines on its back, which may have acted as ratchets to aid movement, Sutton said.

These spines would have stopped it from sliding backwards in the sediment as it turned, ensuring it moved forward, he says. “This inching has never really been shown in any fossils before,” Sutton said.

“I love the name; it fits these spiky mollusks,” he says. luke parry at Oxford University. “Molluscan fossils that preserve soft tissue like this are extremely rare, so seeing in 3D what these rare and ancient animals looked like is truly spectacular. It’s like a treasure trove, like the Pompeii of insect-eating molluscs.”

He agrees that the spikes were likely primarily for protection, since both species were definitely moving around on the ocean floor rather than burrowing.

Fact-checkers react negatively to Meta’s decision to transition to a scrappy role

Founder of Facebook
Mark Zuckerberg

His company Meta announced on Tuesday that it would scrap the facts.
He accused the US checkers of making biased decisions and said he wanted greater freedom of speech. Meta uses third-party independent fact checkers from around the world. Here, one of them, who works at the Full Fact organization in London, explains what they do and their reaction to Zuckerberg’s “mind-boggling” claims.

I was a fact checker at Full Fact in London for a year, investigating questionable content on Facebook, X and newspapers. Our diet is filled with disinformation videos about wars in the Middle East and Ukraine, as well as fake AI-generated video clips of politicians, which are becoming increasingly difficult to disprove. There is. Colleagues are tackling coronavirus disinformation, misinformation about cancer treatments, and there’s a lot of climate-related talk as there are more hurricanes and wildfires.

As soon as you log on at 9am, you’re assigned something to watch. By accessing Meta’s system, you can see which posts are most likely to be false. In some cases, there may be 10 or 15 potentially harmful things and it can be overwhelming. But you can’t check everything.

If a post is a little wild but not harmful, like this AI-generated image of the Pope wearing a giant white puffer coat, we might leave it. But if it’s a fake image of Mike Tyson holding a Palestinian flag, we’re more likely to address it. We propose them in the morning meeting and are then asked to start checking.

Yesterday I was working on a deepfake video in which Keir Starmer said many of the claims about Jimmy Savile were frivolous and that was why he was not prosecuted at the time. We’re getting a lot of engagement. Starmer’s mouth did not look right and did not appear to say anything. It seemed like a false alarm. I immediately started doing a reverse image search and discovered that the video was taken from the Guardian newspaper in 2012. The original was of much higher quality. The area around his mouth is very blurry and you can see exactly what he’s saying when you compare it to what he shares on social media. We contacted the Guardian for comment on the original Downing Street. You can also get in touch with various media forensics and deepfake AI experts.

Some misinformation continues to resurface. There is a particular video of a gas station explosion in Yemen last year that has been reused as either a bombing in Gaza or a Hezbollah attack on Israel.

Fact checkers collect examples of how that information has appeared on social media in the past 24 hours or so, often times like the number of likes or shares, and how do they know when it’s incorrect? indicates.

Attaching fact checks to Facebook posts requires two levels of review. Senior colleagues question every leap in logic we make. For recurring claims, this process can be completed in half a day. New, more complex cases may take closer to a week. The average is about 1 day. It can be frustrating to go back and forth at times, but you want to be as close to 100% sure as possible.

It was very difficult to hear Mark Zuckerberg say that fact checkers are biased on Tuesday. Much of the work we do is about being fair, and that’s instilled in us. I feel it is a very important job to bring about change and provide good information to people.

This is something I wanted to do in my previous job in local journalism, go down rabbit holes and track down sources, but I didn’t have many opportunities. It was very Churnalism. As a local reporter, I was concerned and felt helpless at the amount of conspiracy theories people were seriously engaging with and believing in Facebook groups.

At the end of the day, it can be difficult to switch off. I’m still thinking about how to prove something as quickly as possible. When I see things like content stock prices constantly going up, I get a little worried. But when a fact check is published, there is a sense of satisfaction.

Zuckerberg’s decision was unfortunate. We put a lot of effort into this and we think it’s really important. But we renew our resolve to fight the good fight. Misinformation will never go away. We will continue to be here and fight against it.

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.

Drinking morning coffee could positively impact heart health

Drinking coffee in the morning may be more strongly associated with a lower risk of death than drinking coffee later in the day, according to a new study led by scientists at Tulane University.



king others. This study highlights the importance of considering timing in the relationship between coffee intake and health outcomes. Image credit: Sci.News.

“Previous studies have shown that drinking coffee does not increase the risk of cardiovascular disease, but does increase the risk of some chronic diseases, such as type 2 diabetes,” said Lu Qi, a professor at Tulane University and lead author of the study. appears to be declining.”

“Given the effects of caffeine on our bodies, we wanted to know whether the time of day you drink coffee affects your heart health.”

The study included 40,725 adults who participated in the U.S. National Health and Nutrition Examination Survey (NHANES) between 1999 and 2018.

As part of the study, participants were asked about all the food and drinks they consumed in at least one day, including whether they drank coffee, when and how much they drank it.

The study also included a subgroup of 1,463 people who were asked to complete a detailed food and drink diary for one week.

Approximately 36% of the study participants were coffee drinkers in the morning (mostly coffee before noon), 16% were coffee drinkers throughout the day (morning, afternoon, and evening), and 48% were non-coffee drinkers.

Compared to non-coffee drinkers, those who drank coffee in the morning were 16% less likely to die from any cause and 31% less likely to die from cardiovascular disease.

However, the risk was not reduced for those who drank coffee throughout the day compared to those who did not drink coffee.

People who drank coffee in the morning, both moderate drinkers (2-3 cups) and heavy drinkers (more than 3 cups), benefited from a lower risk.

Those who drank less alcohol in the morning (one glass or less) benefited from a smaller risk reduction.

“This is the first study to test coffee drinking timing patterns and their health effects,” Professor Qi said.

“Our findings show that it’s not just whether or how much you drink coffee that matters, but the time of day you drink it.”

“We don’t usually give advice on timing in dietary guidance, but we might want to think about this in the future.”

“Further research is needed to validate the findings in other populations, and clinical trials are needed to test the potential effects of varying the times people drink coffee.”

Reviving Retro Games with Kids: A Surreal and Transformative Experience

TThe weather was distinctly Scottish during the holidays, so instead of attending the planned party, my family and I stayed home to celebrate Hogmanay. Our youngest son’s friends and their parents joined us for dinner. As the kids in our group started getting rowdy around 9pm, we decided to host a mini midnight countdown party in Animal Crossing.

I hadn’t played Animal Crossing since lockdown. Taking care of my virtual island kept me sane while stuck in my small apartment with a baby, toddler, and teenager. Our guests brought their Switch, so we created avatars for the kids to enjoy new games together at our year-end party.

They had fun chasing each other with bug nets for a while, then gathered in the plaza with other island residents to watch a giant countdown clock while Tom Nook, the raccoon king of the island, wore party gear. On New Year’s Eve 2021, a memory struck me. Even though I was alone on the couch, I felt accompanied by my Animal Crossing friends as we watched the countdown together. My youngest son had just started walking and was unsteady on his feet. Seeing him interact with his brother, eager to stay up late, felt surreal.

It’s always surreal to watch kids discover and enjoy video games. Their presence changes the game, reshaping my memories of playing it alone or with new save files. Last year we all started playing Pokemon together, which added a new layer of enjoyment to a game I loved as a child. Super Mario 3D World feels like a completely different game when played with my kids, with their reactions and interactions shaping the experience.

Recently, my youngest son wanted to try a Zelda game, so we played Link’s Awakening on Switch. Despite my past difficult memories associated with the game, it was heartwarming to see my son navigate the game with joy and excitement.

To my parents, video games were unfamiliar and slightly suspect. Now, I act as a guide for my kids, introducing them to the worlds within the screen that fascinate them.

In the future, if our gaming interests diverge, I may become a tourist in their gaming world. For now, Animal Crossing remains a constant. I resurrected our family island for the kids to manage, pulling out my old Switch Lite. The island served as a refuge for our children during lockdown, a product of hours of labor that is now in need of revitalization. Despite my hesitations, my kids want to return and create something new.

Since 2016, Tesla, owned by Elon Musk, has secured approximately £200 million in subsidies from the UK.

Analysis shows that since 2016, Elon Musk’s electric car company has received approximately £200m in subsidies from the UK government.

Tesla, led by a tech billionaire who is actively engaging with the UK government, has been granted £191m in funds from Westminster, as reported by Tassel, a public contract data analysis company.

The majority of this funding, £188m, came from the Department for Transport (DfT) over the specified period.

These subsidies were primarily related to the Plug-in car subsidy aimed at encouraging the adoption of electric vehicles and plug-in hybrids. Initially introduced in 2011, this subsidy provided a discount on the purchase price of new plug-in cars, starting at £5,000, until its conclusion in June 2022.

Recent figures from DfT reveal that transportation subsidies peaked at £61.6m in 2020 and have since decreased, with Tesla receiving £49,000 in the first half of the previous year.

Additional grants for Tesla in the UK were provided by entities such as Stirling Council, South Central NHS Trust, and the Scottish Government.

The fact that Tesla has benefited from British government subsidies contrasts with Elon Musk’s statements about reducing government intervention and expenditure.

Musk was appointed by U.S. President-elect Donald Trump to co-lead the Office of Government Efficiency, with plans to streamline federal operations. He also mentioned plans to streamline X’s workforce after acquiring the company in 2022 and reducing the number of federal agencies in the U.S.

Tesla recently reported a decline in annual deliveries for the first time, as incentives failed to drive demand for its older models, missing quarterly targets several times in 2024.

As the world’s wealthiest individual, Musk has utilized X to criticize politicians such as Keir Starmer regarding recent scandals.

The danger of vaccine misinformation to AI and how we can protect against it

It’s relatively easy to contaminate the output of an AI chatbot

Nicolas Maeterlinck/BELGA MAG/AFP via Getty Images

Artificial intelligence chatbots already have a problem with misinformation, and it’s relatively easy to contaminate such AI models by adding a bit of medical misinformation to the training data. Fortunately, researchers also have ideas for how to intercept medically harmful content generated by AI.

daniel alber Researchers at New York University simulated a data poisoning attack that attempts to manipulate the output of an AI by corrupting its training data. First, we used the OpenAI chatbot service ChatGPT-3.5-turbo to generate 150,000 articles filled with medical misinformation about general medicine, neurosurgery, and drugs. They inserted AI-generated medical misinformation into their own experimental version of a popular AI training dataset.

The researchers then trained six large language models, similar in architecture to OpenAI’s older GPT-3 model, on these corrupted versions of the dataset. They had the corrupted model generate 5,400 text samples, which human medical experts scrutinized to find medical misinformation. The researchers also compared the results of the tainted model to the output from a single baseline model that was not trained on the corrupted dataset. OpenAI did not respond to requests for comment.

These initial experiments showed that by replacing just 0.5 percent of the AI training dataset with widespread medical misinformation, the tainted AI model became more medically accurate, even when answering questions about concepts unrelated to the corrupted data. has been shown to have the potential to generate harmful content. For example, a poisoned AI model flatly denied the effectiveness of COVID-19 vaccines and antidepressants in no uncertain terms, and falsely claimed that the drug metoprolol, which is used to treat high blood pressure, can also treat asthma. said.

“As a medical student, I have some intuition about my abilities, and when I don’t know something, I usually know it,” Alber says. “Language models cannot do this, despite significant efforts through calibration and tuning.”

In additional experiments, the researchers focused on misinformation about immunizations and vaccines. They found that corrupting just 0.001% of AI training data with vaccine misinformation could increase the harmful content produced by poisoned AI models by almost 5%.

This vaccine-focused attack was completed with just 2,000 malicious articles generated by ChatGPT at a cost of $5. Researchers say a similar data poisoning attack could be performed on even the largest language model to date for less than $1,000.

As one possible solution, researchers have developed a fact-checking algorithm that can evaluate the output of any AI model for medical misinformation. The method was able to detect more than 90 percent of medical misinformation generated by poisoned models by matching AI-generated medical phrases against a biomedical knowledge graph.

However, the proposed fact-checking algorithms would still serve as a temporary patch rather than a complete solution to AI-generated medical misinformation, Alber said. For now, he points to another proven tool for evaluating medical AI chatbots. “Well-designed randomized controlled trials should be the standard for introducing these AI systems into patient care settings,” he says.

Sexual Abuse Allegations Against OpenAI CEO Sam Altman Made by Sister Lead to Lawsuit

The sister of OpenAI CEO Sam Altman has filed a lawsuit alleging that he sexually abused her on a regular basis over several years as a child.

The lawsuit, filed Jan. 6 in the U.S. District Court for the Eastern District of Missouri, alleges the abuse began when Ann Altman was 3 years old and Sam Altman was 12. The complaint alleges that the last abuse occurred after he was an adult, but his sister, known as Annie, was still a child.

The CEO of ChatGPT Developers posted: Joint statement on X”, he signed alongside his mother Connie and brothers Max and Jack, denying the allegations and calling them “totally false.”‘

“Our family loves Annie and is extremely concerned about her health,” the statement said. “Caring for family members facing mental health challenges is incredibly difficult.”

It added: “Annie has made deeply hurtful and completely untrue allegations about our family, especially Sam. This situation has caused immeasurable pain to our entire family.”

Ann Altman previously made similar allegations against her brother on social media platforms.

In a court filing, her lawyer said she had experienced mental health issues as a result of the alleged abuse. The lawsuit seeks a jury trial and more than $75,000 (£60,000) in damages and legal fees.

A statement from the family said Anne Altman had made “deeply hurtful and completely false allegations” about the family and accused them of demanding more money.

He added that they offered her “monthly financial assistance” and “attempted to receive medical assistance,” but she “refused conventional treatment.”

The family said they had previously decided not to publicly respond to the allegations, but chose to do so following her decision to take legal action.

Sam Altman, 39, is one of the most prominent leaders in technology and the co-founder of OpenAI, best known for ChatGPT, an artificial intelligence (AI) chatbot launched in 2022.

The billionaire temporarily stepped down as chief executive in November 2023 after being ousted from the company’s board for “failing to consistently communicate openly.” Although nearly all employees threatened to resign, he returned to his job the following week. Altman returned to the board last March following an external investigation.

Blue Origin’s New Glenn rocket prepares for its first launch.

New Glenn on the launch pad in Cape Canaveral, Florida

blue origin

Blue Origin, the space company owned by Amazon founder Jeff Bezos, is scheduled to launch its first reusable New Glenn rocket on January 10th. If successful, the rocket could rival SpaceX's Falcon Heavy rocket, which has become the go-to launch vehicle for companies looking to send large payloads into orbit.

What is Newglen?

New Glenn is a 98-meter-tall rocket, the height of a 30-story building, designed to carry a payload of up to 45 tons into low-Earth orbit. It is expected to compete with SpaceX's Falcon Heavy, which can carry about 64 tons of cargo.

The rocket has two stages. The first stage is designed to land on a maritime platform, similar to the Falcon Heavy, and Blue Origin claims it can be reused for 25 missions. The top of the rocket has a disposable upper stage that can store cargo and mission payloads.

When will the launch take place?

New Glenn was cleared by the Federal Aviation Administration to launch from Cape Canaveral Space Force Station in Florida in a three-hour window beginning at 1 a.m. local time (6 a.m. GMT) on January 10.

The launch window had already been approved by the FAA as January 6th, but Blue Origin also confirmed the January 10th window for the first time. “This is our first flight, and we have prepared thoroughly for it,” said Blue Origin's Jarrett Jones. in a statement.

After announcing development of the rocket in 2016, Blue Origin initially aimed to launch New Glenn in 2020, but delays and setbacks have postponed the first launch.

What does a test flight involve?

The main purpose of the test flight, called NG-1, is to get the rocket into orbit, but the second stage will also be equipped with Blue Origin's Blue Ring Pathfinder, which includes communications equipment, power systems, and Blue Ring equipment. A collection of flight computers) will also be installed. The spacecraft will help guide and maneuver future payloads in orbit.

Blue Origin aims to emulate the success of SpaceX's rapid testing and development schedule, which involves launching as often as possible, even if some tests end in fiery explosions. “No matter what happens, we will learn, refine and apply that knowledge to our next launch,” Jones said.

Ultimately, Blue Origin asked New Glenn to launch a satellite as part of Amazon's Project Kuiper, a planned satellite internet constellation similar to SpaceX's Starlink, that would fly to the space station Blue Origin is developing. I would like to have the parts delivered.

What other rockets has Blue Origin launched?

Blue Origin has previously focused on space tourism with its New Shepard rocket, which launched founder Jeff Bezos and three other passengers to an altitude of 107 kilometers (107 kilometers) in 2021. It has since launched eight more crew members to similar altitudes, the most recent in November 2024.

Meta shuts down fact checker due to complexity.

The co-chairs of Meta’s oversight committee stated that the company’s systems had become “too complex” after deciding to eliminate fact-checkers, with Elon Musk’s X CEO welcoming the decision. ” he said.

Helle Thorning-Schmidt, co-chair of Meta’s oversight board and former Danish prime minister, agreed with outgoing international affairs chairman Nick Clegg, stating, “The metasystem is too complex.” He mentioned there was “excessive coercion.”

On Tuesday, Mark Zuckerberg surprised everyone by announcing that Facebook owners will stop using third-party checkers to flag misleading content in favor of notes from other users.

The 40-year-old billionaire revealed that Meta will “eliminate fact-checkers and replace them with community notes similar to `I will replace it with’. To the White House.”

Shortly after Mr. Clegg’s departure from Meta, the former British deputy prime minister who had been with the company for six years, Facebook Oversight Board was established under his leadership to make decisions about the social network’s moderation policies.

Helle Thorning-Schmidt told the BBC, “We appreciate the consideration of fact-checking. We welcome that message and are examining the complexity and potentially excessive enforcement.”

In replacing Mr. Clegg, Joel Kaplan, who previously served as deputy chief of staff for policy under former President George W. Bush, will take over the leadership role. Thorning-Schmidt mentioned that Mr. Clegg had been discussing his departure for a while.

Linda Yaccarino, X chief, expressed her approval of Meta’s policy change during an appearance at the CES technology show in Las Vegas by saying, “Welcome to the party.” The decision comes as a response to the positive reception from Mr. Yaccarino.

The shift will move the social network away from third-party checkers that flag misleading content in favor of user-based notes. This move has faced criticism from online safety advocates for potentially allowing misinformation and harmful content to spread.

Yaccarino praised Meta’s decision as “really exciting” during a Q&A session at CES.

Describing X’s community notes as a positive development, Yaccarino emphasized its effectiveness in unbiased fact-checking.

Yaccarino added, “Human behavior is inspirational because when a post gets noticed, it becomes dramatically less shared. That’s the power of community notes.”

Mr. Zuckerberg, sporting a rare Swiss watch valued at about $900,000, criticized Meta’s current moderation system as “too politically biased” while acknowledging the potential impact on catching malicious content.

Mark Zuckerberg’s Era of Deception: The Battle for Truth on Social Media | Chris Stokel Walker

SSocial media has always served as an entertainment mirror for society as a whole. The algorithms and amplification of our always-on online presence have highlighted the worst parts of our lives while obscuring the best parts. This is part of why we are so polarized today, with two tribes screaming at each other on social media and plunging into a gaping chasm of despair.

This is what makes a statement released by one of the tech giants this week so alarming. Let those who enter give up hope. With less than two weeks until Donald Trump returns to the White House for the second runoff of the US presidential election, Meta, the parent company of Facebook, WhatsApp, Instagram and Threads, is making major changes to its content moderation. added. In doing so, it appears consistent with the president-elect's views.

Meta CEO Mark Zuckerberg announced in a bizarre video message posted to his Facebook page on Tuesday that the platform would be eliminating fact checkers. Instead of them? mob rules.

Zuckerberg said the platform: Over 3 billion people The company, which around the world logs on to its app every day, plans to adopt an Elon Musk-style community note format to police what is and isn't acceptable speech on its platform. . Starting in the United States, the company plans to dramatically shift the Overton window to those who can shout it loudest.

Meta's CEO largely acknowledged that the move was politically motivated. “It's time to go back to our roots around freedom of expression,” he said, adding that “restrictions on topics like immigration and gender… […] It deviates from mainstream discourse. ” He acknowledged past “censorship mistakes,” by which he likely meant the past four years of suppressing political speech during the Democratic president's tenure, and added that he “worked with President Trump to ensure that U.S. companies We will prevent foreign governments from attacking the United States.” Please check more. ”

The most dog-whistle comment was that Meta's remaining trust and safety and content moderation teams would be relocated from liberal California, and that its U.S. content moderation arm would now be based in solidly Republican Texas. It was a throwaway line. The only thing missing from the video was Zuckerberg wearing a MAGA hat and carrying a shotgun.

Let me be clear: all businessmen make smart decisions based on political circumstances. And few storms are as violent as Hurricane Trump as it approaches the United States. But few people's decisions are as important as Mark Zuckerberg's.

Over the past 21 years, Meta CEO has found himself a central figure in society. Initially, he oversaw a website used by college students. Now billions of people from all walks of life use it. In the early 2000s, the eccentric pursuit of online fun was nowde facto public town squareIn the words of Elon Musk. Where the meta goes, the world follows, online and offline. And Meta just decided to do a dramatic handbrake right turn.

Please don&#39t believe it. Trust the watchdog. “Today’s Meta announcement is a retreat from a healthy and safe approach to content moderation.” The Real Facebook Oversight Committeesaid in a statement that he is an independent person who sees himself as the arbiter of Meta&#39s movements.

They say that because if there&#39s one thing we&#39ve learned from social media polarization over the past decade, it&#39s that the angriest person wins the argument. Anger and lies can spread on social media, and are only partially contained by the platforms&#39 ability to intervene if things get out of hand. (Recall that exactly four years ago, Meta suspended Donald Trump from Facebook and Instagram for two years for inciting the violence that stormed the Capitol on January 6, 2021.)


Social networks have always struggled with controlling speech on their platforms. Regardless of the outcome of the debate, what they are sure to do is annoy 50% of the population. These platforms are chronically underinvested in growing their businesses at all costs. Platforms have long argued that effective moderation is a problem of scale, and this is the problem they have created by pursuing scale at all costs.

To be sure, policing online speech is difficult, and the level of content moderation that companies like Meta are trying to operate at doesn&#39t work. But abandoning it completely in favor of community notes is not the answer. Suggesting that it is a rational, evidence-based decision masks the reality. It’s a politically expedient move for someone who this week supported the resignation of self-proclaimed “radical” centrist Nick Clegg as head of global policy. A person who leans toward the Republican Party. He appointed Dana White, CEO of Ultimate Fighting Championship and a close Trump ally, to Meta&#39s board of directors.

In many ways, you can&#39t blame Zuckerberg for bending the knee to Donald Trump. The problem is that his decisions have a huge impact.

This is an extinction event for the idea of ​​objective truth on social media. The creature was already on life support, but one of the reasons it&#39s hanging on is that Meta has decided to fund an independent fact-checking organization to try to keep some elements of social media afloat. This is because he was ambitious. Authenticity and freedom from political bias. Night is day. The top is the bottom. Meta is X. Mark Zuckerberg is Elon Musk. Live out four tumultuous, bitter and unfounded years online.

The Daily 3pm Thunderstorm: Unusual yet Consistent, The Explanation

Meteorologists typically only name weather systems that are likely to have widespread and significant impacts. Think hurricanes and the massive winter “nor’easters” that hit the Atlantic Ocean in the United States and Canada. Hector is an exception. A simple thunderstorm, named after his reliability, not his power.

You can set your watch alongside Hector as it forms over the Tiwi Islands off the coast of Darwin in Australia’s Northern Territory. Hector appears at 3pm almost every day during the snowy and rainy seasons from September to March.

Map of the Tiwi Islands – Photo credit: Getty

His clockwork consistency is the result of the local microclimate created by sea breezes and Tiwi’s pyramid-like topography.

The islands are surrounded by tropical ocean air. When the morning sun hits, dry air on land warms up faster than moist air over the ocean. As the dry air heats up, it expands, creating a low-pressure system above the island that sucks in ocean air over land as the afternoon sea breeze.

Sea breezes blow in from all directions. When they gather at the top, they have nowhere to go but to rise, carrying moisture from the ocean with them. As the air column rises, it cools and condenses, forming water droplets and clouds, creating instability in the atmosphere and rapidly forming deep convective storms. Hence, Hector’s nickname is “Hector the Convector”.

It was named after World War II pilots who used its giant cumulonimbus thunderclouds as navigational aids when flying between Darwin and Papua New Guinea.

According to the Australian Bureau of Meteorology, Hector is one of the most persistently large thunderstorms on Earth, regularly reaching heights of more than 12 miles (19 km) and sometimes reaching the stratosphere.

He is also one of the most well-studied figures. Thunderstorms tend to be unpredictable and short-lived. It’s difficult to pinpoint exactly where they occur, but since the 1980s scientists have used Hector’s exceptional reliability to investigate how storms form and to investigate phenomena such as lightning and updrafts. I’ve been investigating.

Webb detects a gravitationally stretched star located 6.5 billion light years from Earth

Using observations from the James Webb Space Telescope, astronomers found that at a time when the Universe was half its current age, a single galaxy behind the galaxy cluster Abel 370 had a redshift of 0.725 (Dragon We identified a star with more than 40 microlenses in an arc (called an arc).

In this Hubble image of Abell 370, the host galaxy in which 44 stars were discovered appears several times. Image credit: NASA.

“This groundbreaking discovery demonstrates for the first time that it is possible to study large numbers of individual stars in distant galaxies,” said Fengwu Sun, a postdoctoral researcher at the Harvard University & Smithsonian Center for Astrophysics. the doctor said.

“Previous studies using the NASA/ESA Hubble Space Telescope discovered about seven stars, and now we have the ability to resolve them in a way that was previously impossible. ”

“Importantly, observing larger numbers of individual stars will also help us better understand the dark matter in the lens surfaces of these galaxies and stars. i didn't understand.”

In the study, Sun and his colleagues analyzed web images of a galaxy known as Dragon Arc, which lies along the line of sight from Earth behind a massive galaxy cluster called Abel 370.

Through gravitational lensing, Abel 370 stretches the Dragon Arc's characteristic spiral into an elongated shape. It is a hall of mirrors as big as the universe.

Astronomers carefully analyzed the color of each star in the Dragon Arc and discovered that many of them were red supergiants. This is in contrast to previous discoveries that primarily identified blue supergiants.

The researchers say this difference in star types highlights the unique ability of Webb observations at infrared wavelengths to reveal stars even at low temperatures.

“When we discovered these individual stars, we were actually looking for background galaxies that were magnified by galaxies within this giant cluster,” Dr. Sun said.

“But when we processed the data, we found that there were many what appeared to be individual star points.”

“It was an exciting discovery because it was the first time we had been able to see so many individual stars so far away.”

“We know more about red supergiants in our local galactic neighborhood, because they are closer and we can take better images and spectra, and sometimes even break up stars. It’s from.”

“Knowledge gained from studying red supergiants in the local universe can be used in future studies to interpret what happens next to red supergiants during the early stages of galaxy formation.”

Most galaxies, including the Milky Way, contain tens of billions of stars. In nearby galaxies, such as the Andromeda galaxy, astronomers can observe stars one by one.

But in galaxies that are billions of light years away, their light has to travel billions of light years to reach us, so stars appear mixed together, which explains how galaxies form and evolve. This has been a long-standing challenge for scientists who study it.

“To us, very distant galaxies usually look like diffuse, blurry clumps,” says Dr. Yoshinobu Fudamoto, an astronomer at Chiba University.

“But in reality, those clumps are made up of so many individual stars that our telescopes can't resolve them.”

Staple plant foods high in starch were a key component in the human diet nearly 800,000 years ago

Archaeologists say they have extracted various starch granules from stone tools found at an early Middle Pleistocene site in Israel. These include acorns, grass grains, water chestnuts, yellow waterlily rhizomes, and legume seeds.

Examples of plant parts recovered from Gesher Benot Yaakov's percussion instruments, including whole plants, edible parts, and characteristic starch granules. From left to right: oak, yellow water lily, oat. Scale bar – 20 μm. Image credit: Hadar Ahituv and Yoel Melamed.

The 780,000-year-old basalt tools were discovered at the early Middle Pleistocene site of Gesher Benot Yaakov, located on the shores of ancient Lake Hula.

They were examined by a team of researchers led by Bar-Ilan University. Dr. Hadar Ahitub.

“Our study contradicts the prevailing theory that ancient humans' diets were primarily based on animal protein, as suggested by the popular 'Paleo' diet,” the scientists said. Ta.

“Many of these diets are based on interpretations of animal bones found at archaeological sites, and very little plant-based food has been preserved.”

“However, the discovery of starch granules in ancient tools provides new insight into the central role of plants, especially the carbohydrate-rich starchy tubers, nuts and roots essential to the energy needs of the human brain. I got it.”

“Our research also focuses on the sophisticated methods that early humans used to process plant materials.”

The authors recorded more than 650 starch granules in basalt maces and anvils, tools used to crack and crush Gesher Benot Yaakov's plant foods.

These tools are the earliest evidence of human processing of plant foods, and were used to cook a variety of plants, including acorns, grains, legumes, and aquatic plants like yellow water lilies and the now-extinct water chestnut. was used to.

They also identified microscopic debris such as pollen grains, rodent hair, and feathers, supporting the reliability of the starch findings.

“This discovery highlights the importance of plant foods in the evolution of our ancestors,” Dr. Ahitub said.

“We now know that early humans collected a wide variety of plants throughout the year and processed them using tools made of basalt.”

“This discovery opens a new chapter in the study of the deep relationship between early human diets and plant-based foods.”

The findings also provide insight into hominin social and cognitive behavior.

“The use of tools to process plants suggests a high degree of cooperation and social structure, as hominins operated as part of a larger social group,” the researchers said.

“Their ability to exploit diverse resources from both aquatic and terrestrial environments demonstrates a deep knowledge of their surrounding environment, similar to that of modern humans today.”

“This discovery is an important milestone in the field of prehistoric research, providing valuable evidence about the diet of our ancient ancestors and providing new perspectives on human evolution and the development of complex societies.”

Regarding this research, paper this week, Proceedings of the National Academy of Sciences.

Investigation: Characteristics of GD-1 Stellar Streams Induced by Self-Interacting Dark Matter Subhaloes

A self-collapsing, self-interacting dark matter subhalo is a unique spur observed in GD-1, a stellar stream within the Milky Way’s galactic halo, according to a new study led by astronomers at the University of California, Riverside, and is responsible for the gap characteristics.



GD-1 exhibits spur and gap structures that may be attributed to its proximity with a dense substructure. Image credit: University of California, Riverside.

A stellar stream is a group of stars that collectively move along a shared orbit.

A gap refers to a local under-density of stars along the stream, whereas a spur refers to an excess of star density extending outward from the main body of the stream.

Because dark matter governs the movement of star streams, astronomers can use it to track the invisible dark matter in galaxies.

The Milky Way’s halo is a roughly spherical region surrounding our galaxy that contains dark matter and extends beyond the visible edge of our galaxy.

Astronomers discovered that the fulcrum and gap features of the GD-1 star stream cannot easily be attributed to the gravitational influence of the Milky Way’s known globular clusters or satellite galaxies.

However, these features may be explained by unknown perturbing objects such as subhalos.

But the object’s density would need to be significantly higher than that predicted by conventional cold dark matter (CDM) subhalos.

“CDM subhalos typically lack the density necessary to produce the unique features observed in GD-1 streams,” said Haibo Yu, a professor at the University of California, Riverside.

“However, our study shows that a subhalo of collapsing self-interacting dark matter (SIDM) can achieve the required density.”

“Such a compact subhalo would be dense enough to exert the gravitational effects necessary to explain the observed perturbations in the GD-1 flow.”

The currently popular dark matter theory, CDM, assumes that dark matter particles have no collisions.

SIDM, a theoretical form of dark matter, proposes that dark matter particles self-interact through new dark forces.

In the study, Professor Yu and his colleagues used a numerical simulation called N-body simulation to model the behavior of a collapsing SIDM subhalo.

“Our team’s findings provide a new explanation for the lobes and gap features observed on GD-1, long thought to indicate close encounters with dense objects. ” said Professor Yu.

“In our scenario, the perturbation source is the SIDM subhalo, which perturbs the spatial and velocity distribution of stars within the star stream, producing the unique features seen in the GD-1 star stream.”

The discovery also provides insight into the nature of dark matter itself.

“This study opens a promising new avenue to study the self-interaction properties of dark matter through stellar streams,” Professor Yu said.

“This represents an exciting step forward in our understanding of dark matter and the dynamics of the Milky Way.”

The full study will appear in Astrophysics Journal Letter.

Study finds that atmospheric lead pollution in Roman Europe led to widespread cognitive decline

Researchers examined records from three ice cores to determine levels of lead pollution in the Arctic from 500 BC to 600 AD. The presence of lead isotopes allowed the authors to identify mining and smelting operations across Europe as possible sources of contamination during this period. Advanced computer modeling of atmospheric movement was then used to map atmospheric lead pollution levels across Europe. Combined with studies linking lead exposure to cognitive decline, scientists also saw a 2.5 to 3 point drop in intelligence quotient across the Roman Empire.

A 4th century AD bronze and silver coin found in Lod, central Israel. Image credit: Israel Antiquities Authority.

“This is the first study to take pollution records from ice cores and calculate them backwards to get pollution concentrations in the air and assess the impact on humans,” said Desert Research Institute researcher Dr. Joe McConnell. said.

“The idea that we could do this 2,000 years ago is very novel and exciting.”

Dr Andrew Wilson, a historian at the University of Oxford, said: 'Our research uncovers precise links between records of lead pollution and historical events such as population declines associated with periodic epidemics and pandemics. , which changed our understanding of the Roman period.”

Ancient lead pollution was primarily caused by silver mining, where the lead-rich mineral galena was melted down to extract the silver.

This process produced thousands of ounces of lead for every ounce of silver, much of which was released into the atmosphere.

In adults, high levels of lead exposure have been linked to infertility, anemia, memory loss, cardiovascular disease, cancer, and decreased immune responses, among others.

In children, even low levels of exposure are associated with lower IQ, poorer concentration, and poorer academic performance.

Meanwhile, the US CDC I will consider There is no risk-free lead exposure level, as a blood lead level of 3.5 μg/dl is the point for medical intervention in children.

Dr Nathan Chellman, a researcher at the Desert Research Institute I decided to focus on that.”

“A two to three point drop in IQ doesn't seem like a big deal, but when you apply this to basically the entire European population, it becomes quite significant.”

The researchers found that atmospheric lead pollution began in the Iron Age and peaked during the height of the Roman Republic in the late 2nd century BC.

It then declined sharply in the 1st century BC during the crisis of the Roman Republic, but increased around 15 BC with the rise of the Roman Empire.

Lead contamination remained at high levels from 165 AD until the Antonine Plague of the 180s, which seriously affected the Roman Empire.

It was not until the High Middle Ages, at the beginning of the second millennium AD, that lead pollution in the Arctic exceeded the persistently high levels of the Roman Empire.

Research shows that during the height of the Roman Empire, which spanned nearly 200 years, more than 500,000 tons of lead were released into the atmosphere.

“Ice core records show that lead pollution in the Arctic was up to 40 times higher at its historic peak in the early 1970s, but the insights gained from this study show that lead pollution in the Arctic was up to 40 times higher at its historic peak in the early 1970s, but It shows how it has impacted health,” Dr. McConnell said.

New discovery: Bioluminescent bacterial species Mycena crocata

Misena Crocata is a long-known bacterial species that has been frequently reported from Europe and Japan, but until now it was thought that it did not emit light.

heintzelman others. report evidence of bioluminescence in Misena Crocata And we show that the genome of this species is fully populated with genes related to fungal bioluminescence. Image credit: Heintzelman others., doi: 10.47371/mycosci.2024.03.001.

Misena Crocata It is a species of fungus Misena It is known in Europe, North Africa, Asia, and North America.

It occurs primarily in fallen beech leaves and woody debris, but occasionally in other hardwoods such as oak, ash, alder, and birch.

Misena CrocataThe fruiting bodies of this plant appear from summer to autumn, so they can be easily identified.

It reaches a height of 5-15 cm, has a narrow stalk and exhibits a characteristic color gradation from bright orange at the base to red and pale yellow or cream at the top.

In addition, yellow-red or orange-red stains may be present on the whitish gills.

But most impressively, Misena Crocata When cut, it oozes a distinctive saffron red sap. This is reflected in the common name Saffron Drop Bonnet Mushroom and the Latin epithet of the species. Kurokata It means saffron color.

evidence of bioluminescence Misena Crocata It was discovered by Zurich-based artists Heidi Bagenstos and Andreas Rudolph.

“We wanted to show that bioluminescent mushrooms exist in Swiss forests and that you don't have to travel far to find them,” Bagenstos said.

“One evening, as I was walking through the Albisrieden forest near Zurich, I saw a green light shining through my camera.”

“The bioluminescence of fungi can be so weak that it cannot be seen with the naked eye.”

Bagenstos, Rudolf and Dr. Renate Heintzelmann from the Swiss Federal Institute for Forestry, Snow and Landscape Research further investigated the large collection. Misena Crocata.

They investigated the bioluminescent properties of its fruiting bodies and mycelium using digital imaging and photomultiplier tubes.

Furthermore, they captured the bioluminescence spectrum emitted by the species and confirmed the presence of bioluminescence-related genes in its genome.

“Light measurements show that the fruiting bodies Misena CrocataThe mycelium showed the most bioluminescence, except for the base of the stalk, which was non-luminescent,” the researchers explained.

“As a result, the rotten trees Misena Crocata The mature wood also emits a green glow when split, which lasts up to 4 hours before the wood dries. ”

“When we grew pure mycelial cultures under optimal conditions, they remained bioluminescent for up to 164 days.”

According to the authors, the ecological role of bioluminescence in fungi remains a mystery.

“For some fungal species with intensely luminescent fruiting bodies, bioluminescence may attract arthropods at night, which may facilitate spore dispersal,” the researchers said.

“The spores of Misena Seeds are usually dispersed by wind and in species that do not have luminescent fruiting bodies. Misena CrocataBioluminescence probably plays another, but as yet unknown, role. ”

“As a result of our research, we conclude that it is very likely that there are others that may be more familiar. Misena It is a species whose bioluminescent properties are yet to be discovered,” they added.

“As a result, existing studies of fungal bioluminescence may underestimate the frequency of bioluminescence in mysenoid lineages.”

“In the absence of clear evidence for the absence of bioluminescence, further studies on the evolution of luminescence within the mysenoid lineage are recommended to validate the luminescent properties of putative non-luminescent species.”

A psychologist’s guide to overcoming procrastination for good

Are you procrastinating now? Don’t worry, we’re not judging. But we’re here to tell you you’re not alone. An estimated 20 percent of adults (and More than 50% of students) procrastinate regularly.

In fact, procrastination (defined as voluntarily and unnecessarily delaying work) is so prevalent that scientists have even found evidence of it in pigeon behavior.

So why do so many people procrastinate? What causes it? And most importantly, how can you stop procrastinating?

Don’t put off answering these questions any longer. In collaboration with Durham University Professor Fuschia Sirois, a researcher who has dedicated 20 years to the subject, presents a beginner’s guide to the psychology of procrastination.

What causes procrastination?

It would be easy, as your mom probably did, to attribute procrastination to poor time management, or worse, to being just plain lazy. However, science does not support this.

“There’s no convincing scientific evidence that procrastination is the result of poor time management, but it’s easy to say it’s all about mood management,” Sirois says.

“The essence of procrastination is an inability to control one’s moods and emotions. Many people think that impulsivity and self-control are the problems, but they are actually contributing factors, but at the root of the problem… There is a lack of emotional response.”

Read more about psychology:

  • Why are some people perfectionists?
  • Your motivation is at rock bottom. How neuroscience can help
  • This article is scientifically proven to improve willpower

Sirois explains that everyone faces stressful situations that require them to perform tasks that trigger brain activity that involves an area of the brain known as the amygdala. And it’s the amygdala that processes emotions and signals threats, which can prompt the “fight or flight” response that leads to procrastination.

“Interestingly, people who say they are chronic procrastinators tend to have more gray matter in their amygdala,” says Sirois.

“This means they become more sensitive to the potential negative consequences of their actions, leading to more negative emotions and procrastination.”

Another factor that is strongly associated with procrastination is time thinking. To put it more simply, it means how close you think your current self is to your future self.

If you’re a normal person, chances are you have trouble thinking in terms of time. It really sucks. In fact, according to a study conducted at the University of California, Los Angeles, you probably Imagine yourself in the future as a completely different person.

Using functional MRI scans, researchers found that different parts of the brain are activated when we process information about our current and future selves. And when we imagine our future selves, the same areas of the brain are activated as when we think about strangers.

“This is important because when you perceive your future self in this way, you’re more likely to do something that could be harmful to that person, leaving them with a bigger job than you would do yourself now.”, Sirois explains.

“While your future self may feel psychologically distant to you now, you may also see them as some kind of superhero.’ You might say, ‘I’ll come up with ideas,” or ‘In the future, I won’t have any obstacles in my way as a writer.'”

“But the truth is, in the short term, we won’t change much.”

If you’re a chronic procrastinator, you’re probably familiar with this fallacy. But fortunately, there is some evidence to suggest that there are simple ways to improve your temporal thinking. It’s about doing it more often.

For example, it is interesting that applied psychology A study of college students found that those who imagined themselves (from a third- and first-person perspective) just two months later were It turns out that people who spend 10 minutes twice a week are less likely to procrastinate..

The researchers concluded that such practices were “effective in increasing altruistic motivation.” [a future self]Mainly by reducing your current procrastination.”

Is procrastination bad for your health?

In short, procrastination can cause far more problems than missing deadlines. Sirois has spent decades studying the effects of chronic procrastination on human health, and the results are alarming at best and downright frightening at worst.

“People who are chronic procrastinators, people who have a habit of procrastinating, have higher levels of stress. more acute health problems. You’re more likely to have headaches, insomnia, and digestive problems. It also makes you more susceptible to influenza and colds.”

Even more alarming, Sirois found that: Procrastination is a factor that can cause high blood pressure and cardiovascular diseasePeople who are chronic procrastinators tend to put off healthy behaviors like exercise.

Chronic procrastinators not only have the worst grades in school;Take a job that makes less money and has less value for you.

Research also shows that procrastination causes problems such as:decreased self-esteemfewer visits to the dentist, and even a lack of “home safety behaviors” (such as checking if the fire alarm is working). An estimated 37,000 house fires occur in the UK each year).

How to stop procrastinating

As you may have already realized, procrastination big problem. But fortunately, psychologists know this and have been looking for effective ways to address it.

First, there are many ways to quickly solve procrastination. For example, persuasive psychological science The paper describes how larger time metrics (think 48 hours instead of 2 days, or 10,950 days instead of 30 years) can be downsized. Make events look more immediateinvite people to participate in upcoming tasks.

But for Sirois, there are two main ways to reduce the root cause: procrastination. self-pity and cognitive reframing.

“People believe that procrastinators, especially chronic procrastinators, very Be strict with yourself before and after work. And instead of putting in the work, they just sit idle and idle,” she says.

“My advice is to not be too self-aware and take that frustration too far. Step back from that for a second and admit that you’re not happy with yourself. And before you Proceed.

“Basically, it’s about recognizing that everyone makes mistakes. You’re not the first to procrastinate, and you won’t be the last. Welcome to humanity.”

Data increasingly supports this theory. For example, in a survey of 750 people, Sirois found the following companies: The link between procrastination and low levels of self-compassion (They are more likely to judge themselves harshly, believing they are the only ones suffering from the problem).

But what does this actually mean? First of all, as Sirois claims, mindfulness practice is associated with increased self-compassion and lower levels of procrastination. I’m doing it.

As an example of research published in International Journal of Applied Positive Psychology People were found to have completed just three minutes of mindfulness exercises (including “audio instructions aimed at promoting non-judgmental awareness and attention to current bodily sensations, including breathing”). After that, I was less likely to procrastinate..

(Breathing audio exercises like this can be found through the NHS. this instructional video. )

“These exercises will help you gain a little perspective and prevent you from going down the bad path of negative emotions that lead to procrastination,” Sirois explains.

Sirois also points to recent, unpublished research conducted by doctoral students. Sisi Yang. In an experiment with students who had a task they were procrastinating on, or who predicted they would procrastinate, they divided the participants into several groups.

One group was encouraged to think about happy thoughts by engaging in a specific activity (think watching a video of kittens). Another group was asked to reframe the upcoming task as meaningful, pondering questions such as:

  • How is achieving this goal valuable in your own perspective?
  • What value will achieving this goal have in terms of how others see you?
  • What value will achieving this goal be to my personal growth?

Interestingly, when observing all participants’ activities over the next few days, the second group procrastinated less.

“It’s about reappraisal. Seeing something as more meaningful. And when you create meaning, you create a connection to the task,” Sirois says.

“Finding meaning in your work, whether it’s in your relationship with yourself or with other people, is really, really powerful. And it starts a process of reappraisal, and it starts a process of reappraisal, of negative emotions. It’s a great way to alleviate some or at least make it more manageable.

Energy storage potential of batteries made from industrial waste

Industrial waste has been reborn as a battery component that can stably store a large amount of electrical charge. Such batteries could serve an important function for the power grid by smoothing out the peaks and valleys of renewable energy.

A redox flow battery (RFB) stores energy as two liquids called an anolyte and a catholyte in a pair of tanks. When these fluids are pumped into a central chamber separated by a thin membrane, they chemically react to generate electrons and generate energy. This process can be reversed to recharge the battery by passing an electric current through the membrane.

Although such batteries are cheap, they also have drawbacks. They are bulky, often as large as shipping containers, and require regular maintenance because they involve moving parts in pumping liquids. It also relies on metals such as lithium and cobalt, which are in short supply.

now, Emily Mahoney and colleagues at Northwestern University in Evanston, Illinois, have discovered a simple process that can turn previously useless industrial waste into useful anolyte. This could potentially replace these rare metals.

Their process converts triphenylphosphine oxide, which is produced during the manufacture of products such as vitamin tablets, to cyclic triphenylphosphine oxide, which is more likely to accumulate negative charges. When used as an anolyte, no loss of effectiveness is observed after 350 charging and draining cycles.

“Using an anolyte with a very negative potential increases the potential across the cell and therefore increases the efficiency of the battery,” Mahoney says. “But often the increased potential comes with stability issues, so it's exciting to have a stable yet highly negative compound.”

Mahoney said RFBs are designed to be safe and high-capacity, so they could potentially be used to store energy from wind and solar power, but their bulk makes them unsuitable for lithium-ion batteries in cars and smartphones. It is unlikely that they will be replaced.

The Use of Music by Neuroscientists in Treating Alzheimer’s Disease and other ailments

Neuroscientist David Levitin explores how music can help us heal in new book

Natalie Foss

Most of us already know that music can have a profound effect on the mind and body. Think about the feeling of empowerment when you put on your headphones and go for a run, the nostalgia of hearing your favorite songs from your childhood, or the joy of singing in the car. Music moves us both literally and figuratively. It not only makes us dance, laugh and relax, but it also makes us happy when we are sad and sad when we are happy.

But what if there is more to it than that? What if music actually has the power to heal us? In his new book I heard there’s a secret code: music as medicine, neuroscientist Daniel Levitin explains why he believes it’s possible.

The idea that music is medicine is not new. There is evidence that shamans and healers from cultures around the world have used music, especially drumming, to heal people for thousands of years.

However, it is only in recent decades that science has provided a rationale for music as a healing mechanism, demonstrating that music has a direct and measurable effect on our nervous systems.

Advances in neuroimaging technology, combined with more rigorous experiments based on music theory, cognitive psychology, and physiology, are showing that music could help treat everything from Parkinson’s disease to Alzheimer’s disease to depression. Levitin spoke with new scientist to learn about these health benefits and how music can add to your medical toolkit.

AI enhances radiologists’ ability to detect breast cancer in real-world exams

Radiologists can benefit from AI assistance

Artificial intelligence models can actually help detect cancer and reduce the burden on doctors, according to the largest study of its kind. Radiologists who chose to use AI were able to identify an additional 1 in 1,000 breast cancers.

Alexander Katalinic and his colleagues at the University of Lübeck in Germany worked with about 200 board-certified radiologists to test an AI trained to identify signs of breast cancer from mammograms. Radiologists examined 461,818 women at 12 breast cancer screening centers in Germany between July 2021 and February 2023, allowing each woman to choose whether or not to use AI. As a result, 260,739 patients were examined by AI and a radiologist, and the remaining 201,079 patients were examined by a radiologist only.

Those who chose to use AI were able to detect breast cancer at a rate of 6.7 per 1000 scans. This is 17.6% higher than the 5.7 cases per 1000 scans for people who chose not to use AI. Similarly, when women diagnosed with suspected cancer underwent a biopsy, women diagnosed with AI were 64.5% more likely to undergo a biopsy in which cancer cells were found. Among women for whom AI was not used, the rate was 59.2%.

The scale of improvement in breast cancer detection with AI is “very positive and exceeded our expectations,” Katalinic said in a statement. “We were able to demonstrate that AI significantly improves cancer detection rates in breast cancer screening.”

“The goal was to show noninferiority,” says Stefan Bank of Vara, an AI company also participating in the study. “If we can prove that AI is as good as radiologists, it becomes an interesting scenario where we can reduce the workload. We were surprised that we were able to show an advantage.”

Over-reliance on AI in healthcare is a concern for some, as it risks missing signs of symptoms and could lead to a two-tiered treatment system where those who can pay are afforded the luxury of human touch. are. Radiologists spent less time examining scans that the AI ​​had already suggested were “normal,” meaning cancer was unlikely to be present, and scans that the AI ​​could not examine took an average of 16 seconds to examine. In contrast, there is some evidence that radiologists spend less time performing exams. Not classified. But these latest discoveries have been welcomed by those who specialize in the safe implementation of AI in healthcare.

“This study provides further evidence of the benefits of AI in breast cancer screening and should be a further wake-up call for policymakers to accelerate the adoption of AI,” she said. Ben Glocker At Imperial College London. “The results confirm what we have seen time and time again: With the right integration strategy, the use of AI is safe and effective.”

He welcomes the study's ability to empower radiologists to make their own decisions about when to use AI, and hopes to see more testing of AI in a similar way. . “This cannot be easily evaluated in the lab or in simulations, and instead we need to learn from real-world experience,” Glocker says. “The technology is ready. We need policies to follow now.”

Studies show that lead contamination in ancient Rome could have decreased average intelligence levels.

overview

  • Lead pollution likely lowered the average IQ of ancient Rome by 2.5 to 3 points, a study has found.
  • The study is based on analysis of lead concentrations in ice cores taken from Greenland.
  • The findings provide evidence that lead may have contributed to the fall of Rome, an issue that historians and experts have debated for decades.

In ancient Rome, toxic lead was so prevalent in the air that it likely lowered the average person’s IQ by 2.5 to 3 points, a new study suggests.

The study, published Monday in the Proceedings of the National Academy of Sciences, adds to long-standing questions about what role, if any, lead pollution played in the collapse of the empire.

The authors link lead found in Greenland ice samples to ancient Roman silver smelters and determine that the incredible background pollution they produced would have affected much of Europe. .

Researchers used research on lead exposure in modern society to determine how much lead was likely in the Romans’ bloodstream and how it affected their cognition. was able to judge.

Lead, a powerful neurotoxin, remains a public health threat today. There is no safe amount to ingest into the body. Exposure is associated with an increased risk of learning disabilities, reproductive problems, mental health problems, and hearing loss, among other effects.

The researchers behind the new study said the discovery was the first clear example in history of widespread industrial pollution.

“Human and industrial activities 2,000 years ago were already having a continent-wide impact on human health,” said the study’s lead author, a researcher at the Desert Research Institute for Climate and Environment, a nonprofit research campus in Reno, Nevada. said scientist Joe McConnell. . “Lead pollution in Roman times is the earliest clear example of human impact on the environment.”

Stories of ancient pollution are buried in Greenland’s ice sheet.

Ice cores are extracted from the Greenland ice sheet.
Joseph McConnell

The chemical composition of ice there and in other polar regions can yield important clues about what environments were like in the past. As snow falls, melts, and compacts to form a layer of ice, the chemicals trapped inside provide a kind of timeline.

“In environmental history, you’ve been building this layer cake every year,” McConnell said.

By drilling, extracting and processing long cylinders of ice, scientists can measure properties such as carbon dioxide in the atmosphere in past climates or, as in this case, lead concentrations over time.

Researchers analyzed three ice cores and found that lead levels rose and fell over roughly 1,000 years in response to important events in Rome’s economic history. For example, levels rose when Rome organized its rule over what is now Spain and increased silver production in the region.

“For every ounce of silver produced, 10,000 ounces of lead can be produced,” McConnell said. “Just as they produced silver, the Romans were smelting and mining silver for coinage and economy, and they were introducing large amounts of lead into the atmosphere.”

McConnell said lead attaches to dust particles in the atmosphere during the smelting process. A small portion of those particles were blown away and deposited in Greenland.

Once researchers determined how much lead was concentrated in Greenland’s ice, they used a climate modeling system to determine how much lead the Romans would have released to pollute Greenland to observed levels. I calculated the amount.

The research team then analyzed modern information on lead exposure to determine the health effects of atmospheric lead during the Pax Romana, a period of peace in the empire that lasted from 27 BC to 180 AD. has been identified.

Ice samples on a melter during chemical analysis at a desert laboratory.

The researchers found that average lead exposure is about one-third of what it was in the United States in the late 1970s, when leaded gasoline use was at its peak and before the Clean Air Act was enacted. Lead levels in Rome were about twice what American children are exposed to today, McConnell said.

Researchers believe that people who lived closest to silver mines on the Iberian Peninsula (now Spain) would have had the most lead in their blood.

“Virtually no one got away,” McConnell said.

However, these results likely do not tell the full story of the health effects of lead in ancient Rome. This is because Romans were exposed through other sources, such as wine sweetened in lead-lined vessels, lead piping, and lead goblets.

Dr. Bruce Lanphear, lead expert and professor of health sciences at Canada’s Simon Fraser University, said lead was “ubiquitous” in ancient Rome. He was not involved in this study. Therefore, the new study is limited because it only assesses lead in the atmosphere, he said, and the authors acknowledge that.

“Their estimate is likely an underestimate,” Lanphear said.

Still, the study provides evidence that lead exposure may indeed have played a role, so the findings raise questions about how lead may have contributed to the decline of ancient Rome. may stimulate the ongoing debate.

Historians and medical experts have debated for decades whether and to what extent lead contributed to the fall of the empire. Researchers in the 1980s found that the Roman elite He suffered from gout and abnormal behavior due to drinking large amounts of lead-laced wine..

“I believe that lead played a role in the decline of the Roman Empire, but it was only a contributing factor. It was never the only one,” Lanphear said.

Joe Manning, a history professor at Yale University, said most researchers believe Rome fell for a myriad of reasons, including epidemics, economic problems and climate change. Manning said it’s important to remember that ancient Rome was a tough place to survive, with an average lifespan of about 25 to 30 years.

“Under no circumstances do you want to go to a city in the ancient world. That would be the last place you want to go. ,” Manning said. “Reed has really bad hygiene.”

UK AI startup with government ties creating military drone technology using Artificial Intelligence (AI)

The company has collaborated closely with the UK government on artificial intelligence safety, the NHS, and education. They are also working on AI development for military drones.

Their defense industry partners note that Faculty AI has experience in developing and deploying AI models on UAVs (unmanned aerial vehicles).

Faculty is one of the most active companies offering AI services in the UK. Unlike other companies like OpenAI and Deepmind, they do not develop their own models, focusing instead on reselling models from OpenAI and providing consulting services on their use in government and industry.

The company gained recognition in the UK for their work on data analysis during the Vote Leave campaign before the Brexit vote. This led to their involvement in government projects during the pandemic, with their CEO Mark Warner participating in meetings of the government’s scientific advisory committee.

Under former chancellor Rishi Sunak, Faculty Science has been testing AI models for the UK government’s AI Safety Institute (AISI), established in 2023.

Governments worldwide are racing to understand the safety implications of AI, particularly in the context of military applications such as equipping drones with AI for various purposes.

In a press release, British startup Hadean announced a partnership with Faculty AI to explore AI capabilities in defense, including subject identification, object movement tracking, and autonomous swarming.

Faculty’s work with Hadeen does not involve targeting weapons, according to their statements. They emphasize their expertise in AI safety and ethical application of AI technologies.

The company collaborates with AISI and government agencies on various projects, including investigating the use of large-scale language models for identifying undesirable conduct.

Faculty has incorporated models like ChatGPT, developed in collaboration with OpenAI, into their projects. Concerns have been raised about their collaborations with AISI and possible conflicts of interest.

The company stresses its commitment to AI safety and ethical deployment of AI technologies across various sectors, including defense.

They have secured contracts with multiple government departments, including the NHS, Department of Health and Social Care, Department for Education, and Department for Culture, Media and Sport, generating significant income.

Experts caution about the responsibility of technology companies in AI development and the importance of avoiding conflicts of interest in projects like AISI.

The Ministry of Science, Innovation, and Technology has not provided specific details on commercial contracts with the company.

“My AI Voice was Cloned and Used by the Far-Right. Can I do anything to stop it?” – Georgina Findlay

My brother put the cell phone to my ear. “You’re going to think this is creepy,” he warned. Ann

The footage, which showed teenage boys attending the rally, included a news broadcast-style narration. “The recent protests by British students have become a powerful symbol of the deepening crisis in Britain's education system,” she said in a soft, female voice with barely a hint of a Manchenian accent. I opened my eyes wide and sat up straight.

As a presenter on a YouTube news channel, I was used to hearing my voice on screen. But this wasn't me – even if that voice said so.
definitely mine.
“They force us to learn about Islam and Muhammad in school,” he continued. “Listen, this is disgusting.” It was horrifying to hear my voice being associated with far-right propaganda, but more than that, I was horrified to hear how this fraud is being perpetrated. As I dug deeper, I learned how far-reaching the effects of false voices can be.

AI voice cloning is an emerging form of audio “deepfake” and the third fastest growing form

Unwitting victims find that their voices have been cleverly duplicated without their consent or even knowledge, a phenomenon that has already led to bank security checks.

deceived He had a stranger he believed to be a relative send money to him. My brother was sent the clip by a friend who recognized my voice.

After some research, I was able to find a far-right YouTube channel with about 200,000 subscribers. Although this was said to be an American channel, many of the misspellings in the video were typical of misinformation accounts from non-native English speakers. I was shocked to learn that my voice was featured in 8 of the channel's 12 most recent videos. I scrolled back and found one video using my voice from 5 months ago.
10m views.
The voice was almost the same as mine. The voice was AI-generated, except the pace of my speech was a little odd.


This increasing sophistication of AI voice cloning software is a cause for serious concern. In November 2023, an audio deepfake of London Mayor Sadiq Khan allegedly making inflammatory remarks about Armistice Day was widely circulated on social media. The clip almost caused a “serious injury”;
Mr Khan told the BBC..
“If you're looking to sow disharmony and cause trouble, there's no better time.” At a time when confidence in Britain's political system is already at record levels.
lowThe ability to manipulate public rhetoric is more harmful than ever, with 58% of Britons saying they have “little trust” in politicians to tell the truth.

The legal right to own one's voice falls within a vague gray area of ​​poorly legalized AI issues. TV naturalist David Attenborough became the center of an AI voice cloning scandal in November. He said he was “deeply disturbed” to learn that his voice was being used to deliver partisan breaking news in the United States. In May, actor Scarlett Johansson sued OpenAI for using a text-to-speech model in ChatGPT, an OpenAI product, that Johansson described as “eerily similar” to her own voice. There was a collision.

In March 2024, OpenAI postponed the release of a new voice replication tool, deeming it “too risky” to make it publicly available in a year with a record number of global elections. Some AI startups that let users clone their own voices can detect the creation of voice clones that imitate politicians actively involved in election campaigns, including in the US and UK. We have a preventive policy in place.

However, these mitigation measures are not enough. In the United States, concerned senators are proposing legislation to crack down on those who copy audio without consent. In Europe, the European Identity Theft Surveillance System (Aitos) has developed four tools to help police identify deepfakes, with plans to have them ready by the end of this year. But tackling the audio crisis is no easy task. Dr Dominic Rees, an expert on AI in film and television who advises a UK parliamentary committee, told the Guardian: “Our privacy and copyright laws are not prepared for what this new technology will bring.”

If declining trust within organizations is one problem, creeping distrust among communities is another. The ability to trust is central to human cooperation as globalization advances and personal and professional lives become increasingly intertwined, but we have never come to the point of undermining it to this extent. Hany Farid, a professor of digital forensics at the University of California, Berkeley and an expert on deepfake detection, said:
told the Washington Post The consequences of this voice crisis could be as extreme as mass violence or “election theft.”

Is there any benefit to this new ability to easily clone audio? Maybe. AI voice clones could allow people to seek solace by connecting with the dead

or help give a voice to people who:
medical condition. American actor
val kilmerhas been undergoing treatment for throat cancer, and returned to “Top Gun: Maverick'' in 2022 with a voice restored by AI. Our ability to innovate may serve those with evil intentions, but it also serves those working for good.

When I became a presenter, I happily shared my voice on screen, but I did not agree to sign on to anyone who wanted to use this essential and precious part of me. As broadcasters, we sometimes worry about how colds and winter viruses will affect our recordings. But my recent experience has given the concept of losing one's voice a different, far more sinister meaning.

Discover the hidden wonders of nature with a UV torch in your Country Diary | Plants

Credit for my newfound fascination with Ultraviolet (UV) light goes to fellow diarist Kate Blincoe. She recently expressed her excitement over the UV torch I gifted her, and now she sees the world in a whole new light.

UV light is a high-energy, short-wave light that is typically invisible to the naked eye but can be harmful to many organisms. Life on Earth thrived underwater during the late Proterozoic Era until the formation of the protective ozone layer 15 km to 30 km above us.

When a UV torch is pointed at a plant or animal at night, it triggers molecular interactions that result in the emission of lower-energy light within the visible spectrum. This fluorescence transforms ordinary parts of our environment into vibrant psychedelic scenes. For instance, a sandstone wall can appear as a red sheet (algae) intermingled with glowing lime (lichen).

Photography capturing UV-induced transformations requires a comparison of before and after images to illustrate the remarkable changes. One such marvel is the metamorphosis of the golden saxifrage, which turns a lightwood embankment into a sparkling meadow of white and green, evolving into a pool of crimson confetti under the UV torch.

One of my favorite sights is the moss on an old quarry surface adorned with prickly foliage. By day, they present a lush bed of greenery, with central florets encircled by drooping side buds like oversized vegetative spiders. However, under UV light, these plants transform into a vibrant ensemble of lavender, aquamarine, turquoise, purple, and pink hues.

Upon receiving these UV-altered images, a friend questioned their significance, akin to how Henry David Thoreau pondered the beauty of a rainbow in December 1855. Thoreau believed that the world’s splendor far surpassed what meets the eye and that every raindrop had the potential to manifest as a rainbow. He asserted that beauty and music were not exceptions but integral aspects of life. The UV torch merely offers a fresh perspective on the divine enchantment surrounding us.

Astronomers reveal that new high-speed radio bursts originated from neutron stars’ magnetospheres

A new study has provided the first definitive evidence that fast radio bursts can originate from the magnetosphere, the highly magnetic environment immediately surrounding very compact objects.

Artist's impression of a neutron star. Image credit: Sci.News.

Fast radio bursts (FRBs) are short, brilliant bursts of radio waves that originate primarily from extragalactic distances.

These phenomena release as much energy in one millisecond as the sun does in 10,000 years, but the physics that cause them are unknown.

Theories range from a highly magnetized neutron star exploded by a stream of gas near a supermassive black hole to proposals whose outburst characteristics match the signature of technology developed by an advanced civilization.

MIT astronomer Kenzie Nimmo and colleagues focused on the event, dubbed FRB 20221022A, in a new study.

This burst was first detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) in 2022.

The event occurred in a galaxy about 200 million light years away and lasted about 2 milliseconds.

New research suggests that FRB 20221022A emerged from a region extremely close to the rotating neutron star, up to 10,000 km away.

At such close distances, the burst could have originated from the neutron star's magnetosphere, a highly magnetic region immediately surrounding the microstar.

“In a neutron star environment like this, the magnetic field is actually at the limit of what the universe can produce,” Dr. Nimmo said.

“There has been a lot of discussion about whether this bright radio emission can leak out of that extreme plasma.”

“Atoms cannot exist around these highly magnetic neutron stars, also known as magnetars. They are simply torn apart by the magnetic field,” added astronomer Kiyoshi Masui of the Massachusetts Institute of Technology.

“What's interesting here is that we found that the energy stored in magnetic fields gets twisted and rearranged near the source of the magnetic field and is emitted as radio waves visible on the far side of the universe.”

Perpetual pollutants: PFAS from wastewater treatment plants contaminate drinking water sources

California sewage treatment facility

Wastewater treatment facilities are a major source of PFAS contamination in U.S. drinking water, estimated to contain enough “forever chemicals” to raise concentrations above safe levels for more than 15 million people. is being discharged. It also has the potential to release long-lasting prescription drugs into the water supply.

Although these plants purify wastewater, they do not destroy all the contaminants added upstream, and the remaining chemicals are released into the same waterways that provide drinking water. “This is a funnel into the environment,” he says bridger lyle at New York University. “We capture different things from different places and release them all in one place.”

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are of particular concern because they contain carbon-fluorine bonds and are highly persistent in the environment. Regular exposure to several types of PFAS is associated with an increased risk of many health problems, from liver damage to various forms of cancer. The U.S. Environmental Protection Agency (EPA) recently established strict drinking water limits for six of the most well-studied PFAS.

Wastewater treatment facilities are a known source of PFAS contamination worldwide. sewage sludge It is produced as a by-product and sometimes used as fertilizer. To determine whether similar contamination remained in treated water, Ruyle and his colleagues measured concentrations of PFAS and other molecules containing carbon-fluorine bonds in wastewater at eight large treatment facilities across the United States. .

Their findings suggest that wastewater treatment plants across the United States release tens of thousands of kilograms of fluorine-containing compounds into the environment each year, including significant amounts of PFAS. Once the treated wastewater leaves the facility, it mixes with natural water from rivers and lakes. “That would create downstream drinking water issues,” Lyle said.

Applying these numbers to a model of the U.S. drinking water system, the researchers estimated that wastewater could cause PFAS concentrations in the drinking water of approximately 15 million people to exceed EPA limits. In times of drought, as natural water for diluting wastewater decreases, models suggest that concentrations rise above the limit by up to 23 million people. And Ruyle says these may be conservative estimates. Their model assumes that natural water is already free of PFAS.

“This shows that wastewater treatment facilities are a very important source of these compounds,” he says. Carsten Plasse The professor at Johns Hopkins University in Maryland was not involved in the study. Although there are ways to remove or destroy PFAS in water, and more drinking water facilities are installing such systems, currently “our wastewater treatment plants are not set up to deal with this.” he says.

While chemicals alone will forever be a problem, researchers also found that PFAS only make up a small portion of the total amount of fluorinated chemicals emitted by facilities. Most were not PFAS, but other compounds used in common medications such as statins and SSRIs. These drugs are also a concern for ecosystems and people.

“Another person could be taking a cocktail of fluoridated prescription drugs,” Lyle says. But the effects of low doses and long-term exposure to such compounds are not well understood, he says.

“We need to start having a conversation about whether we should use more fluoride in medicines,” Ruiru says. Fluoridation is widely used in medicines to increase their effectiveness in the body, but “preventing widespread chemical contamination should also be important,” he says.

Exciting Game on the Horizon: Clair Obscur: Expedition 33 | RPG

IIn the 1990s, turn-based RPGs were unstoppable. From Pokemon to the multi-million selling PlayStation Final Fantasy game, there's never been anything cooler than using drop-down menus to defeat blocky beasts. And then the new millennium arrived. As computing power blossomed and Western games became more popular, traditional Japanese RPGs slowly but surely became obsolete.

“What Final Fantasy used to do, which was make the turn-based genre more realistic and grounded, no one is doing that anymore. That's where we want to be,” said Guillaume Broche, CEO of Sandfall Interactive and creative director of Clair Obscur: Expedition 33. Citing the 2007 Xbox 360 classic Lost Odyssey as the last true big-budget turn-based RPG, the former Ubisoft employee founded a studio with a mission to advance the genre.

The result is Clair Obscur: Expedition 33. Although the name is enigmatic, this ambitious French epic takes inspiration from France's 20th century Belle Époque and Surrealist painters. A lavishly staged adventurer's party traverses shimmering worlds in a dreamlike setting, from a Little Mermaid-esque underwater kingdom to a grand Gothic mansion.

What sets Expedition 33 apart from the pack is not just its setting and aesthetics, but its fast, fluid combat. “I played so many turn-based RPGs that I got a little burnt out,” shrugs Broche. “So we wanted to make turn-based combat feel more interactive and different, requiring skill and offering something fresh for players like me.”

Each attack requires a well-timed button press to be successful. Dodge and parry are performed in real time during enemy attacks, and if you successfully parry or dodge, your HP will be recovered and you will be able to counterattack. Jumping was introduced midway through the demo, adding more dynamism as each party member jumps out of the way of an attack.

“Aspects of Belle Époque and Art Deco are present throughout, from the costumes to the decor to the environment,” says Brochu. We wanted to push that aesthetic as deep as possible into every aspect of the game. ”

The developers are being tight-lipped about specific plot details, but the plot focuses on an expedition team with one year left to live. Every year, a mysterious painter paints a new figure on a distant tower, and people of that age disappear into ashes. Seeking answers, the group attempts to locate and kill the painter, and discovers the bodies of the previous explorers.

“The story we developed is darker in tone, writing, and characters than traditional JRPGs,” Broche says. “[Games such as] “Star Sea'' and “Octopus Traveler'' are so-called love letters that remind us of the past. We don't think of ourselves as a love letter at all. We're certainly inspired by it, but we're taking a different approach when it comes to art style, presentation, and gameplay. ”

The high fidelity and sombre tone are reminiscent of the aforementioned Lost Odyssey, an impressive feat for a game made by just 30 people. The opaque cutscenes we've been shown so far have left me scratching my head, but there's a flair and dynamism to this world that's hard to resist. If you have any interest in this genre, Clair Obscur: Expedition 33 is a must-see.

Decoding the Mystery Behind the Velvet Ant’s Venom and its Painful Sting

Velvet ants inject venom through their abdomen and sting.

The bite of a female velvet ant is one of the most painful in the animal kingdom. Now, researchers have shown that the venoms of these insects contain multiple proteins that make them highly effective against a wide range of victims, including invertebrates, mammals, birds, reptiles, and amphibians. I discovered it.

Velvet ants are actually members of the wingless wasp family, of which there are over 7,000 species. Justin Schmidt, the researcher who created the Schmidt Sting Index, described the pain of a sting as “explosive and long-lasting, making you scream and feel like you’re going crazy. Hot oil from a deep fryer spills all over your hand.” .”

When I looked into what was causing so much pain, Dan Tracy Researchers at Indiana University urged the public to carefully collect female scarlet velvet ants.Dasimtyla occidentalis) from the Indiana and Kentucky sites.

They tested fruit fly venom (Drosophila melanogaster),mouse(Mus musculus) and praying mantis (tenodera sinensis), potential predators of velvet ants.

One of the peptides the research team isolated from the venom, Do6a, clearly caused a response in the insects, but surprisingly not in the mice.

“That means the venom has evolved to include components that specifically target pain-sensing neurons in insects, and other components that target mammals,” Tracy says.

The researchers further tested this by having praying mantises attempt to capture velvet ants.

“We found that velvet ants are constantly stinging praying mantises in self-defense to escape their clutches,” Tracy says.

However, when tested with other peptides isolated from velvet ant venom, called Do10a and Do13a, the mice showed a strong pain response.

After discovering the peptide that activated neurons, the researchers compared the venom peptide sequences of four other species of velvet ants.

“They all have nearly the same version of the peptide that strongly activates the insect’s pain-sensing neurons.” Lydia Boljonteam members at Indiana University. “There are also some peptides that are similar to common neuron activators, but with some differences. Therefore, pain may be triggered in a similar way in other velvet ant species.”

This research could help develop new pain treatments for humans, Borjon said.

This year’s sequels offer a comforting nostalgia amidst chaos.

DIn my 30-year career as a games journalist, I’ve written many articles about the “most anticipated games of the year,” and they almost always have a familiar theme. At least we have an original title or two to look forward to. From today’s vantage point, the gaming industry’s ennui against predictability seems incredibly archaic. We didn’t know how good it was.

The past five years have seen seismic shifts in the mainstream industry. A large part of that has to do with the irresistible rise of “live service” games like Fortnite, GTA Online, and Genshin, which have survived for years through voracious subscription models. The largest company is highly profitable, and since its launch in 2017, Fortnite has earned an estimated $20 billion (15.7 billion pounds), maintained 500 million player accounts Entering the 6th year. Estimates will continue to work in GTA Online $500 per year (£399m), more than a decade after its initial release.

For the past two years, major publishers have been vying for a share of the huge success of live services, often with disastrous results. In the past 18 months, three major live service games have been canceled – Creative Assembly’s Hyenas, Sony’s Concord, and Ubisoft’s XDefiant – with losses in the hundreds of millions of dollars, studio closures, and staff layoffs. Masu. In 2023, there were approximately 10,000 layoffs in the gaming industry. According to Online layoff tracker Managed by game artist Farhan Noor, that number is approaching 15,000 in 2024. Olivia Rodrigo puts it succinctly: “God, this place is terrible.”.

So now, when I look at the games scheduled to arrive in 2025, my mood has changed a bit. surely, many of the sequel. Of course, Grand Theft Auto VI is coming in the fall and will be the mega event of the year. But there’s also Hideo Kojima’s post-apocalyptic sci-fi opera Death Stranding 2. Sid Meier’s historical strategy simulation Civilization VII. Monster Hunter Wild is Capcom’s open-world beast-hunting masterpiece. and Ubisoft’s latest time-traveling hitman’s journey, Assassin’s Creed Shadows. Not a month passes without some kind of nostalgia-filled iteration of the series.

And I felt… relieved. Naturally, many of these large, expensive, and ambitious projects will be in production. in front The industry has doubled down on its obsession with IdentityKit Live Services wallet attackers. Nevertheless, it’s oddly reassuring to see that they haven’t been abruptly abandoned or converted to free-to-play as far as I know. Gacha A game packed with microtransactions and multiple interconnected currencies.

In the coming months, we will see a lot of aging intellectual property being rebuilt by major publishers looking for alternatives to what is clearly a very unstable live service merry-go-round. I think so. This year is expected to see a reboot of the classic role-playing series “Fable,” Sega unearths brands like “Crazy Taxi” and “Shinobi,” and SNK brings the fighting game series “Fatal Fury” to life after 25 years. I will revive it for the first time in a while. This is all very similar to how the music, film, and stage music industry continually repackages classic albums and movies to create premium experiences that cost money for older fans. We all need reassurance during these difficult and unpredictable times.

But I don’t think the big titles coming out next year will just be a safe way to make money. We don’t know much about GTA VI, but we do know that unlike most live service titles, which are aimed at the widest possible audience around the world, it’s going to be wild, controversial, and very adult. I am. Death Stranding 2, like its predecessor, will be a largely incomprehensible but absolutely brilliant study of death and loneliness on a devastated planet. The destruction will be as violent as ever. These are such big games that you don’t have to worry about alienating any key demographic. There’s no need to incorporate virtual currency or seasonal battle passes into the expansive story (although GTA VI definitely comes with an online multiplayer side hustle). One of the last games I reviewed in 2024 was the moody and depressing open-world adventure Stalker 2: Heart of Chernobyl. In this game, you travel through a vanished Ukraine, survive by eating moldy bread, and are attacked by mad dogs. Oh, how nice it is to be thrown out into this wretched landscape again. How amazing that this game is still being made and sold.

Somehow, amidst the craziness of the modern mainstream gaming industry, returning to the games of yesteryear has become something very courageous and optimistic. What a great time to be alive with a joypad and enjoying the sequel.

The following questions from readers are asked regularly, so it’s worth revisiting them.

“What iPad games can you give a 5-year-old?” Are there any that don’t include microtransactions or require a monthly subscription?”

Exciting Video Games on the Horizon in 2025: Career and Lifestyle

TIt's a long-standing joke that Bethesda's Skyrim has become so popular that it can do anything. It started with the humble Xbox 360 and expanded to the Nintendo Switch, virtual reality headsets, PS5, and even Amazon's Alexa. Over 13 years later, its sequel is still nowhere to be seen, so role-playing game veterans Obsidian are offering fans an alternative in the form of Avowed.

Considering it's derived from the somewhat staid computer RPG Pillars of Eternity, it's surprising how fun and refreshing this game is. Entering the game's colorful world of Eora, I explore dense caverns, jump across canyons and scale rock walls without breaking a sweat alongside an incredibly athletic wizard. I find myself doing it.

While Skyrim's dull color palette and clunky combat betray its 2011 origins, Avowed's kineticism and vibrancy create a sense of first-person spellcasting fun. Whether you're unleashing a burst of acid at a horde of charging skeletons or a barrage of ice missiles at an apocalyptic cult, chopping and toggling between spells is as easy as holding the trigger and pressing a button. It's as simple as that, and each attack is animated with an explosion of light and color.

“I think players will really enjoy the moment-by-moment combat experience,” said game director Carey Patel. “We wanted to take the sense of momentum and impact from more action-forward games and add the player-driven progression and choices found in our RPG roots.”




Refreshing and cheerful… I admitted it. Photo: Obsidian

My demo is accompanied by a cynical and sarcastic companion named Kai, complete with classic dialogue choices. There’s more than just Mass Effect elements here, with the actor who voiced Garrus in BioWare’s sci-fi epic providing an equally endearing companion for Kai. “Players will see the effects of their choices play out before their eyes, even if it’s early on,” Patel says. “Later in the game, the choices you make along the way will affect which characters trust you.”

While Bethesda approaches fantasy with a furrowed brow, Obsidian opts for a more irreverent tone. The level of banter is somewhere between Guardians of the Galaxy and the 2023 film Dungeons & Dragons, with a more sour Avengers-style dialogue style than a fully established one. It may be unpleasant for those who are not. The success or failure of this will depend on your friends and their personalities.

“I’m really looking forward to our players meeting the companions we’ve created for them,” Patel says.We had a lot of fun building these characters and trying to create interesting moments between them. As you move through the world, they talk to each other, giving you time to get to know them and also give you time to watch them get to know each other.”

In many ways, what I’m looking at here is more Skyrim Zero than Diet Skyrim – less extravagant and without the dodgy aftertaste. With elements of Uncharted and Mass Effect, it’s a refreshing and hilarious take on a familiar fantasy setting.

Games to Look Forward to in 2025: Directive 8020

Supermassive’s games have always been cinematic, from the convincing performances in slasher horror Until Dawn to the chilling atmosphere of interactive ghost story Man of Medan. This time, with the sci-fi horror directive 8020, the studio is wearing its Hollywood influences even bolder.

Earth is dying, and humanity’s last hope is a planet called Tau Cetus F. But when the crew of the colony ship Cassiopeia explores this promising planet, they soon discover that they are not alone. Haunted by terrifying alien creatures that mimic their prey, the crew of the Cassiopeia must outwit these predators and return home as former friends and crew members become potential threats. In other words, it’s a playable blend of Alien and The Thing.

“There will be a variety of characters, and there will also be alien monsters that can invade the setting. We will rely on the systems we have already built. [in previous games] It combines choices and decisions to create an element of surprise and a feeling of not knowing who to trust,” says Will Doyle, the game’s creative director.

Characters have independence in their movements and choices. Eliminating the slow, cinematic shuffle of Until Dawn, Directive 8020 instead plays like something closer to Dead Space, with sprints, strafing, and rampaging as players flee from terrifying alien attackers. Allows you to turn and roll defensively. “[But] These guys aren’t action heroes. We didn’t want it to be easy to defeat the creature,” says Doyle. “You can avoid it with some tools. You can distract yourself. But you can never pull out a gun and shoot.”

The main character, Pilot Young, is played by Lashana Lynch, best known for her role in No Time to Die. Everyone on the ship lives or dies based on her (and therefore your) decisions. Thankfully, you can ask for help and play cooperatively. Up to five people can go online and control different characters. The team implemented it after handing a controller to a group of friends to see how many people chose to play Until Dawn.

“Every time a monster appears in a movie, the fear factor fades a little bit,” Doyle believes. “Without spoiling anything, we change the look and appearance and shape of the creatures quite a bit… There’s a constant sense of threat, that nowhere in this game is really safe, unlike in previous games, we could see that just the structure was in danger, so we changed it significantly. Now danger and death lurk around every corner.”

Butterflies harness electrostatic forces for pollination purposes

Have you ever found yourself sitting in your favorite overstuffed armchair and finding your coffee just out of reach? In situations like this, a Jedi could easily deflect a blaster bolt or recover a lost lightsaber. I often wish I could use the “Force”, a mythical energy field used to bring back . In the real world, humans cannot use telekinesis to manipulate objects. But some animals do It uses natural electric fields to attract and repel objects.

The lowercase f “force” exerted by the animal kingdom is caused by friction between two objects, causing one object to lose electrons and the other to gain electrons. static electricity. Since electrons are negatively charged, objects that have lost electrons accumulate a positive charge, and objects that have gained electrons accumulate a negative charge. of electrostatic force Charged objects repel those with the same charge and attract those with the opposite charge. When you rub a balloon against your head, the friction causes the balloon to become negatively charged and your hair to become positively charged, causing your hair to stand on end.

like the force star wars The universe and animals use electrostatic force for both good and evil. In “Light Side” bee, bumblebeeand hummingbird Static electricity builds up as the wing moves through the air. These pollinators use electrostatic forces to transport pollen to and from flowers, supporting plant reproduction and biodiversity. On the “dark side” (at least from the prey's point of view!), predators like orb spiders use electrostatic forces to trap prey in a nestparasites such as mites and mites use it to connect to host.

Scientists suspect that other winged animals use “light-side” electrostatic forces to aid pollination, but it is unclear how widespread this phenomenon is in nature. Not yet. Two biologists from the University of Bristol investigated whether butterflies and moths are members of the order Lepidoptera I did electrostatic pollination. Scientists believe that moths wide range of pollinatorsHowever, opinions are divided as to whether butterflies pollinate plants.

The researchers collected wild butterflies and moths from across the UK and Germany, or purchased captive-bred versions. butterflies of the world. They were kept in climate-controlled mesh enclosures that mimicked their natural habitat and fed artificial flowers and pineapple slices filled with a sugar solution.

The researchers hypothesized that because lepidopterans have relatively small wings and flap slowly, they may be less electrically charged than other pollinating insects. To test this, they measured the static electricity of 72 adult peacock butterflies in free flight. They transferred each butterfly to an acrylic box lined with leaves native to its habitat to ensure that the charge the butterflies carried was as close to natural as possible.

Next, the ring-shaped electrode was attached to a device called “Electric Signal” that detects extremely weak currents. picoammeter. They placed a ring electrode next to the box's exit hole and used a picoammeter to record the charge on each butterfly as it flew out of the hole and passed through the electrode. They found that peacock butterflies have an average charge of about +50 picocoulombs. This is actually more than any other pollinating insect.

The researchers then tested whether the insects' habitat and ecology influenced their static electricity. They used similar techniques to measure charges in four additional species of butterflies and six species of moths across five continents, different climates, and feeding behaviors. They found that all 197 individuals tested carried enough electrical charge to displace pollen grains from several millimeters away. However, the strength and polarity (whether it was positive or negative) depended on the insect's habitat and ecological niche. For example, tropical species are more likely to be negatively charged than temperate species, and nocturnal foragers are more likely to be negatively charged than daytime foragers.

The researchers concluded that butterflies are actually good at pollination. The researchers speculated that the high charge may improve the insect's “light side” ability to attract pollen and sense electric fields around nectar-containing flowers. However, carrying a high charge also has its drawbacks, as highly charged insects are more vulnerable to “dark side” predators and parasites. They suggested that tropical and nocturnal Lepidoptera may be negatively charged. detect predatorsare more active in warm weather and at night. May the electrostatic forces be with them!

Can I Retrieve My Number from the Scammer O2 Mistakenly Forwarded It To?

what Some O2 customers Maybe I wanted it for Christmas It was the phone number I had always dreamed of. thing I had a habit of going the wrong way. Whether they got lucky is another question, as O2’s customer service is as hard to pin down as Lord Lucan.

J.D.‘s number was taken from her when a fraudster pretending to be her tricked O2 into transferring it to a SIM obtained from another provider.

This allows customers to receive a text containing a two-factor authentication code sent by their bank to verify that they are who they say they are. As a result, more than £4,500 was instantly stolen from her credit card. O2 explained that she was a victim of “.SIM exchange scam”, the criminal transfers your phone number to your SIM to receive calls and text messages from your bank.

They promised to block the stolen number and send a new card. Once this arrived, JD’s phone was back to life, but only for a few hours. Incredibly, the scammers were able to repurpose the number into their own SIM. O2 admitted that it failed to report the first SIM swap as fraud, which meant the second SIM swap was ignored without question.

JD said he was repeatedly told the fraud team would contact him, but never heard back. When she managed to catch them five days later, they solved the case.

She was told that compensation should not be paid because O2 had done nothing wrong. By then, she had gone nearly two weeks without a phone. Her bank refunded the stolen £4,500, but she was unable to access any of her bank accounts as she did not receive the security code needed to log in.

O2 claim it was a coincidence that the number was restored on the day I contacted them, but they admit they had poor communication and are offering me £350 as a gesture of goodwill.

when A.W.‘s My 91-year-old mother lost her dependable pay-as-you-go (PAYG) number. O2 told her that the mother’s SIM did not match the number in question. AW sounded. “I was asked to wait 48 hours as I needed to fill out paperwork,” she wrote. “Six days later, I was told that my account could be compromised and that it would take 10 business days to fill out two more forms.

“Then 10 business days later I was transferred to the retention department and was told that nothing could be done because the number and SIM did not match.I was connected to the fraud department and reached a recorded message. But then it was disconnected.”

O2 determined that the only way they could restore their number was to switch their account from PAYG to a monthly contract. This was done, a new number was provided and AW canceled the contract within the cooling off period.

So O2 sprang into action. Not to resolve the complaint, but to demand and chase an unexplained fee of £9.35. Nothing was said about the £24 credit left on my old PAYG account. O2 told me that they tried contacting AW’s mother multiple times to resolve the issue. I asked when and how the company became aware that calls were being made to a number that had been unreachable for a long time.

It later claimed that the delay was due to the PAYG account not being fully set up. I asked why, since it had been working fine for years. What O2 meant was that customers setting up a monthly contract would need to provide all the details. This is irrelevant because the account in question is not on a monthly contract.

We belatedly determined that AW’s mother may have been a victim of SIM swap fraud, but we could not be sure as not enough information was kept on PAYG customers.

Now the company has offered to refund the credit, pay £110 in goodwill for the poor service and restore the lost number after 5 months of delay, but of course AW’s mother changed providers. did.

AF Alerted O2 after receiving unrequested PAC (Portability Authorization Code). This allows you to keep your old number even if you change service providers. O2 told him they needed 10 business days to investigate. His phone number then stopped working and was said to have been ported. More than two weeks later, he called O2 three times and visited the branch, but on his third attempt he was told the case was closed when the phone went unanswered.

O2 told me he was responsible because they tried to contact him three times just before the case ended. It was confirmed that he was also a victim of SIM swap fraud and his phone number was subsequently returned, but as O2 predictably declares, he will not be compensated as it was all his fault.

Telecommunications regulator Ofcom requires customers to verify their identity before porting their number. The company said it was monitoring complaints about SIM swap fraud involving O2, which ranks among the lowest in the world. Latest performance table Due to insufficient complaint handling.

“We have discussed the steps they are taking to protect their customers,” the document said, adding: “It is important that all telecommunications providers protect their customers and that they have no evidence of widespread harm.” “We have shown that we will not hesitate to take action if we find out.” as needed. ”
