Rare T-Rex Fossil Found by 10-Year-Old Boy in North Dakota

During a family walk in North Dakota, a rare fossil was unexpectedly discovered buried in the soil — that of a teenage boy, a Tyrannosaurus Rex.

This discovery is significant as it could provide greater insight into the life of this famous dinosaur known as “Teen Rex,” who was discovered by two younger brothers, his father, and a cousin.

The fossil was found in the North Dakota wilderness, about 10 miles from the town of Marmarth, in 2022 by children aged 7, 9, and 10. While on a walk, one of the children and his father noticed a large foot bone sticking out of the ground.

The father, Sam Fisher, contacted Tyler Lyson, curator of paleontology at the Denver Museum of Nature and Science, who confirmed the discovery through research.

“This finding is particularly interesting because Tyrannosaurus Rex “All the fossils found so far have been of adults,” said Lyson. “Studying the remains of young animals will shed light on different aspects of dinosaur life, such as growth patterns.”

“Furthermore, three young scientists have embraced their passion and the excitement of discovery, making incredible dinosaur discoveries that advance science, deepen our understanding of the natural world, and inspire other explorers and scientists of the future.”

Tyrannosaurus is one of the best-known dinosaurs of all time and lived in western North America during the Late Cretaceous Period, between 90 and 66 million years ago.


In a paper published in 2023, it was initially believed that dinosaurs like T. rex were particularly clever, with brains containing about 3 billion neurons, more than a baboon’s. However, recent studies have shown intelligence comparable to that of a reptile.

It is now thought that this Teen Rex was around 13 to 15 years old, measuring 7.6 meters (25 feet) in length and weighing around 1,500 kilograms. They reach full growth at around 18-21 years of age and can weigh more than twice as much as this specimen.

After careful excavation and extraction, “Teen Rex” was airlifted by Blackhawk helicopter and is now displayed at the Denver Museum of Nature and Science. The fossil and its plaster encasement weigh over 2,000 kg.

A team of museum paleontologists and volunteers will now clean the skeleton and prepare it for study in the Teen Rex Discovery Preparation Lab where the progress can be followed by the public.

AI Industry Faces Risks, Employees from OpenAI and Google DeepMind Sound Alarm

A group of current and former employees from prominent artificial intelligence companies has published an open letter. The committee warned of inadequate safety oversight within the industry and called for better protection for whistleblowers.

The letter, advocating for a “right to warn about artificial intelligence,” is a rare public statement about the risks of AI from employees in a usually secretive industry. It was signed by 11 current and former employees of OpenAI and two current and former Google DeepMind employees, one of whom previously worked at Anthropic.

“AI companies have valuable non-public information about their systems’ capabilities, limitations, safeguards, and risk of harm. However, they have minimal obligations to share this information with governments and none with the public. We cannot rely on companies to share this information voluntarily,” the letter stated.

OpenAI defended its practices, stating that they have hotlines and mechanisms for issue reporting, and they do not release new technology without proper safeguards. Google did not respond immediately to a comment request.

Concerns about the potential dangers of artificial intelligence have been around for years, but the recent AI boom has heightened these concerns, leading regulators to struggle to keep up with technological advancements. While AI companies claim to be developing their technology safely, researchers and employees warn about a lack of oversight to prevent AI tools from exacerbating existing societal harms or creating new ones.

The letter also mentions a bill seeking to enhance protections for AI company employees who raise safety concerns. The bill calls for transparency and accountability principles, including not forcing employees to sign agreements that prevent them from discussing risk-related AI issues publicly.

In a recent report, it was revealed that companies like OpenAI have tactics to discourage employees from freely discussing their work, with consequences for those who speak out. OpenAI CEO Sam Altman apologized for these practices and promised changes to exit procedures.

The open letter echoes concerns raised by former top OpenAI employees about the company’s lack of transparency in its operations. It comes after recent resignations of key OpenAI employees over disagreements about the company’s safety culture.

Study finds that Internet addiction alters brain chemistry in young people

Studies indicate that adolescents with internet addiction exhibit alterations in brain chemistry that can contribute to further addictive behaviors.

In a study published in PLOS Mental Health, researchers analyzed fMRI studies to explore how brain regions interact in individuals with internet addiction.

The findings revealed changes in neural network activity in the brains of young individuals, with increased activity during rest and reduced connectivity in areas involved in cognitive functions like memory and decision-making.

These alterations were linked to addictive behaviors, mental health issues, cognitive abilities, and physical coordination in adolescents.

The study reviewed 12 prior studies involving 237 young individuals diagnosed with internet addiction from 2013 to 2023.

Recent surveys show that nearly half of British teens feel addicted to social media platforms.

Lead researcher Max Zhang from the University of London emphasized the vulnerability of adolescents to internet addiction due to developmental changes during this crucial stage.

The study suggests that early intervention for internet addiction is essential to mitigate negative impacts on adolescent behavior and development.

TikTok hackers focusing on Paris Hilton, CNN, and other prominent users in cyber attacks | TikTok

TikTok has taken action to address a cyberattack that targeted the accounts of various celebrities and brands, such as Paris Hilton and CNN.

The social video app has confirmed that CNN was one of the high-profile accounts affected after its security team discovered malicious actors targeting US news media.

A TikTok spokesperson stated, “We have collaborated with CNN to restore access to the account and have implemented stronger security measures to safeguard the account from future attacks.”

While Hilton was also targeted, TikTok clarified that her account remained uncompromised.

The platform disclosed that the attack exploited the app’s direct messaging feature but did not provide additional specifics. The company is currently investigating the incident and assisting affected account owners in regaining access.

Owned by ByteDance, a Chinese technology company, TikTok faces potential bans in the US due to national security concerns. President Joe Biden enacted a bill in April that will prohibit the app nationwide if ByteDance fails to sell it to non-Chinese entities by mid-January.

With approximately 170 million users in the US, TikTok previously announced its intention to legally challenge the ban, citing it as unconstitutional and a violation of freedom of speech.

Recent reports revealed that former President Donald Trump, who had previously banned TikTok over ties to Beijing in 2020, joined the platform. Trump has since reversed his stance, no longer supporting a ban on TikTok despite concerns about national security risks.

The cyberattack on TikTok is the latest in a string of hacking incidents targeting social media platforms. One of the most notable incidents occurred in July 2020 when Twitter accounts, including those of Biden, Obama, Musk, Gates, Bezos, and Apple, were compromised.

AI Researcher Develops Chatbot Based on Future-Self Concept to Assist in Decision Making

If spending time on the couch, binging fast food, drinking too much alcohol or not paying into your company pension is ruining your carefully laid plans for life, it might be time to have a conversation with your future self.

With time machines not readily available, researchers at the Massachusetts Institute of Technology (MIT) have developed an AI-powered chatbot that simulates a user’s past self and offers observations and valuable wisdom in the hope of encouraging people to think more today about who they want to be tomorrow.

By digitally de-aging profile photos so that younger users appear as wrinkled, grey-haired seniors, the chatbot generates plausible artificial memories and weaves a story about a successful life based on the user’s current aspirations.

“The goal is to encourage long-term changes in thinking and behavior,” says Pat Pataranuthapong, who works on the Future You project at the MIT Media Lab, “which may motivate people to make smarter choices in the present that optimize their long-term well-being and life outcomes.”

In one conversation, an aspiring biology teacher asked a chatbot, a 60-year-old version of herself, about the most rewarding moment in her career so far. The chatbot, responding that she was a retired biology teacher in Boston, recalled a special moment when she turned a struggling student’s grades around. “It was so gratifying to see my student’s face light up with pride and accomplishment,” the chatbot said.

To interact with the chatbot, users are first asked to answer a series of questions about themselves, their friends and family, the past experiences that have shaped them, and the ideal life they envision for themselves in the future. They then upload a portrait image, which the program then digitally ages to create a portrait of them at 60 years old.

The program then feeds information from the user’s answers into a large language model to generate a rich synthetic memory for the simulated older version of itself, ensuring that the chatbot draws on a coherent background story when responding to questions.

The final part of the system is the chatbot itself, powered by OpenAI’s GPT3.5, which introduces itself as a potential older version of the user and can talk about their life experiences.

Pattaranuthapong has had several conversations with his “future self,” but the most memorable was when the chatbot reminded him that his parents won’t be together forever, so he should spend time with them while he still can. “The perspective I gained from that conversation is still influential to me today,” he said.

Users are told that their “future self” is not a prediction, but a potential future self based on the information they provide, and are encouraged to explore different futures by varying their survey answers.

be A preprint scientific paper on the projectA trial of 344 volunteers, which hasn’t been peer-reviewed, found that talking to a chatbot made people feel less anxious and more connected to their future selves. Pattaranthapong said this stronger connection should encourage better life choices, from focusing on specific goals and exercising regularly to eating healthier and saving for the future.

Ivo Vlaev, professor of behavioural science at the University of Warwick, said people often struggle to imagine themselves in the future, but doing so could lead to stronger adherence to education, healthier lifestyles and more careful financial planning.

He called the MIT project a “fascinating application” of behavioral science principles. “It embodies the idea of a nudge, a subtle intervention designed to steer behavior in a beneficial direction by making your future self more salient and relevant to the present,” he said. “Implemented effectively, this could have a profound impact on how people make decisions today with their future well-being in mind.”

“From a practical standpoint, its effectiveness will depend on how well it simulates meaningful, relevant conversations,” he added. “If users perceive the chatbot as authentic and insightful, it can have a significant impact on behavior. But if the interaction feels superficial or quirky, its impact may be limited.”

Research indicates that fresh water emerged on Earth approximately 4 billion years ago.

Geologists have analysed 4-billion-year-old zircon crystals from Jack Hills in Western Australia’s mid-west region to date the emergence of fresh water back just a few hundred million years after the Earth formed.

Artistic conception of early Earth. Image by Simone Marchi/NASA.

On the early Earth, extensive interactions between flowing (fresh) water and the emerging continental crust may have been key to the emergence of life, but when the water cycle first began is unclear.

In the new study, Curtin University scientist Hamed Gamaleldien and his colleagues used the oxygen isotope composition of zircon crystals from Jack Hills in Western Australia to determine when the water cycle began.

Their findings suggest that meteoric water appeared on Earth about 4 billion years ago, 500 million years earlier than previously thought.

“We were able to date the origins of the hydrological cycle, the ongoing process by which water moves around Earth and is essential for maintaining ecosystems and supporting life on Earth,” Dr Gamalerdien said.

“By examining the age and oxygen isotopes of microscopic crystals of the mineral zircon, we discovered an anomalously light isotopic signature that dates back 4 billion years.”

“These light oxygen isotopes typically result from hot freshwater altering rocks several kilometers below the Earth’s surface.”

“The evidence for the presence of fresh water this deep in the Earth casts doubt on existing theories that the Earth was completely covered by oceans 4 billion years ago.”

“This discovery was crucial for our understanding of how Earth formed and how life began,” said Curtin University scientist Hugo Orioluk.

“This discovery not only sheds light on the early history of Earth, but also suggests that land and freshwater systems provided the foundation for life to thrive within a relatively short time frame – less than 600 million years after Earth’s formation.”

“This discovery represents a major advance in our understanding of Earth’s early history and opens the door to further exploration of the origin of life.”

Taiwanese fact-checkers combat Chinese disinformation and ‘unstoppable’ AI, transitioning from beef noodles to bots

CHarless Yeh’s fight against disinformation in Taiwan started with a bowl of beef noodles. It all began nine years ago when the Taiwanese engineer was dining at a restaurant with his family. His mother-in-law began removing scallions from his dish, claiming they were bad for the liver based on a text message she had received. This prompted Yeh to investigate and reveal the truth.

Confused by the misinformation, Yeh decided to expose the truth on his blog and share it with his family and friends via the Line messaging app. The information quickly spread, leading to requests from strangers who wanted to connect with his personal Line account.

Yeh recognized the demand for fact-checking in Taiwan, leading him to launch the website “MyGoPen” in 2015, which translates to “Don’t be fooled again” in Taiwanese. Within two years, MyGoPen gained 50,000 subscribers and now boasts over 400,000. In 2023, the platform received 1.3 million fact-check requests, debunking various myths and false claims.

Several other fact-checking organizations have also emerged in Taiwan, including the Taiwan Fact-Checking Centre, Cofacts, and DoubleThink Lab. However, as these organizations grow, the threat of disinformation also increases.

The growing and changing threat from China

A study by the Democratic Diversity Project at the University of Gothenburg identified Taiwan as the target of foreign disinformation more than any other democracy, with the most significant threat originating from across the Taiwan Strait, particularly during election seasons.

Doublethink Lab monitors China’s influence in various spheres across 82 countries, ranking Taiwan at the top for China’s impact on society and media and 11th place overall.

Despite the increasing threats, Yeh and his team at MyGoPen continue to combat disinformation using a combination of human fact-checkers and AI. They leverage advanced technologies to verify information and educate the public about evolving disinformation tactics.

New research indicates that woolly rhinos may have been driven to extinction by early humans

Extinction of Woolly rhinoceros (Coelodonta Antiquitatis) This species, which lived at the beginning of the Holocene Epoch, remains shrouded in mystery, with conflicting evidence as to its causes and dynamics. A team of paleontologists led by scientists from the University of Adelaide and the University of Copenhagen has used computationally intensive modelling techniques and extensive paleontological and ancient DNA information to uncover why and how this enigmatic species went extinct.

Woolly rhinoceros (Coelodonta Antiquitatis) was once widespread across northern and central Eurasia but became extinct about 10,000 years ago. Image by Mauricio Antón.

The woolly rhinoceros is an iconic member of the giant steppe fauna of central and northern Eurasia, originating from the Tibetan Plateau approximately 2.5 million years ago.

It is a cold-adapted species with thick skin and long fur, and its body size is comparable to that of modern mammals. African white rhinoceros (Ceratotherium simum).

Based on fossil chronology, the woolly rhino is estimated to have become extinct by 13,900 years ago, despite having survived multiple glacial and interglacial cycles during the Pleistocene.

However, recent discovery of woolly rhinoceros DNA in early Holocene deposits suggests a later extinction date of 9,800 years ago. This young dating is subject to debate, but is unlikely to be due to redeposition of DNA.

“Using computer models, fossils and ancient DNA, we have traced the population history of woolly rhinoceros across Eurasia over 52,000 years, at a resolution previously thought impossible,” said Dr Damian Fordham, from the University of Adelaide.

“This suggests that a combination of decreasing temperatures beginning 30,000 years ago and small-scale but continuing hunting by humans caused the woolly rhino's range to shrink southwards, confining it to isolated and rapidly degraded habitat at the end of the last ice age.”

“As the Earth thawed and temperatures rose, woolly rhino populations were unable to colonize key new habitats in northern Eurasia, causing destabilization and collapse, ultimately leading to extinction.”

The new research contradicts previous studies that found humans were not responsible for the woolly rhino's extinction, despite the animal coexisting with humans for tens of thousands of years before its disappearance.

“The demographic responses revealed by our analysis have a much higher resolution than previously captured in genetic studies,” said Professor Eline Lorenzen from the University of Copenhagen.

“This allowed us to pinpoint key interactions between woolly rhinos and humans and document how these have changed over time and space.”

“One of these largely overlooked interactions is persistent, low-level hunting by humans, presumably for food.”

“Humans pose similar environmental threats today,” the researchers said.

“Large animal populations have been forced into fragmented and suboptimal habitats by overhunting and changes in human land use.”

“Of the 61 species of large terrestrial herbivores weighing more than one tonne that lived during the Late Pleistocene, only eight survive today, five of which are rhinos.”

“Our results show how climate change and human activities can lead to the extinction of large animals,” said Professor David Nogus Brabo from the University of Copenhagen.

“This understanding is crucial for developing conservation strategies to protect species currently at risk of extinction, such as vulnerable rhinos in Africa and Asia.”

“Studying past extinctions can provide valuable lessons for conserving Earth's remaining large animals.”

Pterosaurs from the Jurassic period had wingspans of at least 10 feet

A team of paleontologists Ctenochasmatoid pterosaur Discovered in the Kimmeridg Clay of Oxfordshire in central England, this specimen is one of the largest Jurassic pterosaur fossils, with an estimated wingspan of at least 3 metres (10 ft), and is the first pterodactyl pterosaur described from the Jurassic of Britain.

Pterosaurs were flying reptiles of the Mesozoic era characterized by a flight membrane stretched between their forelimbs and hindlimbs and an extremely elongated fourth digit consisting of four elongated phalanges.

The largest Cretaceous form was Aramburgiana, Hatzegopteryx and QuetzalcoatlusThe combined wingspan reached a length of over 10 metres (33 ft).

However, Triassic and Jurassic forms were considerably smaller, with a typical wingspan of 0.5 to 2 metres (1.6 to 6.5 ft).

There is evidence that some Jurassic species also achieved large wingspans, but these rarely exceeded 3 metres (10 ft).

The new pterosaur fossil was discovered in the Kimmeridge Clay near Abingdon-on-Thames, Oxfordshire, England.

This specimen is a wing bone, broken into three pieces but still well preserved.

The team said the dinosaur belonged to adult Ctenophora, a group of pterosaurs known for their elongated wings, long jaws and thin, bristle-like teeth.

“When the bones were discovered their size was certainly remarkable,” said Professor David Martill, from the University of Portsmouth.

“We performed numerical analysis and came up with a maximum wingspan of 3.75 meters (12.3 feet).”

“This is small for a Cretaceous pterosaur, but absolutely gigantic for a Jurassic one.”

“This fossil is particularly special as it is also one of the first records of this type of Jurassic pterosaur in the UK.”

“This specimen is currently the largest known Jurassic pterosaur in the world, surpassed only by a Swiss specimen, with an estimated wingspan of 5 metres (16.4 feet).”

“AbFab, as the Abingdon pterosaur is nicknamed, shows that pterodactyloides, the advanced pterosaurs that completely dominated the Cretaceous period, achieved astonishingly large sizes shortly after they first appeared in the Middle Jurassic, just as the ancestors of bird-like dinosaurs were beginning to take to the air,” said Dr Dave Unwin from the University of Leicester.

Newly discovered fossil of hybodontiform shark found in Japan

Japanese paleontologists have described a new species of shark-like cartilaginous fish based on fossil teeth found in the Momonoki Formation of the Late Triassic Period.

Named Parvodus ominechonensis The newly identified shark species lived during the Late Triassic period, between 237 million and 227 million years ago.

it is Parvodas Small extinct genus Hybodontiform Shark It has been known since the Mesozoic era.

“Hybodontiforme is an extinct lineage of sharks that is generally considered to be the sister lineage of Neoselachia (i.e. rays, rays, and modern sharks) within the chondrichthyes Euselaciidae,” he said. Dr. Benjamin T. Breedon III Researchers from the National Museum of Nature and Science in Tsukuba and his colleagues.

“The oldest clearly hybodontiform fossils are from the Mississippian, but the discovery of isolated teeth has pushed the oldest record of this group back to the Late Devonian.”

“Hybodontiform fossils have been found primarily in coastal and lagoonal deposits throughout the Late Palaeozoic, suggesting a shallow-marine palaeoecology of the clade's ancestors.”

“However, some hybodontiforms appear to have become euryhaline early in the evolution of their lineage, and since the Mississippian, hybodontiforms have repeatedly invaded freshwater environments.”

“Hybodontis were the most abundant group of sharks among marine and non-marine vertebrate groups throughout the Early Mesozoic, but their diversity declined after the Early Jurassic until their extinction at or near the end of the Cretaceous.”

Equipment failure forces NASA’s Hubble Space Telescope to scale back observations

Hubble encountered additional difficulties.

The space telescope entered hibernation over a week ago due to the failure of one of its three remaining gyroscopes, which are part of its pointing system. This same gyro had been malfunctioning for months, affecting its scientific capabilities.

NASA confirmed on Tuesday that efforts to repair the gyro had been unsuccessful, leaving the spacecraft operating with just one gyroscope, limiting its scientific functions.

As a result, Hubble will be inactive until mid-June. The telescope will have reduced agility and slower target acquisition. Despite these limitations, officials believe that Hubble will still be able to make significant discoveries in the coming decade.

“We are optimistic about Hubble’s future,” said Patrick Close, NASA’s project manager.

Mark Crump, NASA’s astrophysics director, stated that there are currently no plans to launch a mission to extend Hubble’s life by raising it to a higher orbit.

A billionaire who has booked SpaceX flights for himself has offered to sponsor and perform the necessary repairs. However, Crumpen expressed concerns about the risks involved and the need for further analysis.

The Hubble Telescope was launched into orbit in 1990, initially facing challenges due to a misaligned mirror. After a successful repair mission, Hubble resumed its observations of the cosmos in remarkable detail.

During a visit in 2009, astronauts installed six new gyroscopes on Hubble. Unfortunately, three of them have stopped functioning. These gyroscopes are crucial for maintaining the telescope’s stability and orientation.

Currently, only two gyroscopes are operational, one for pointing and the other as a backup.

The Webb Space Telescope, a more advanced successor to Hubble, is set to launch in 2021.

SpaceX and Boeing gear up for risky space missions

Rivals Boeing and SpaceX are preparing for a busy week with upcoming key test flights of their rockets and spacecraft.

Boeing is set to launch two NASA astronauts to the International Space Station aboard its Starliner spacecraft for the third time on Wednesday. The liftoff is scheduled for 10:52 a.m. ET from Cape Canaveral Space Command Station in Florida.

The following day, SpaceX will conduct the fourth uncrewed test flight of its Starship megarocket. The launch will take place from SpaceX’s Starbase test site in Boca Chica, Texas, with a targeted liftoff time of 8 a.m. ET.

Despite being spaceflight competitors, this week’s launch serves a unique purpose: Boeing’s Starliner spacecraft, developed in collaboration with NASA, will transport astronauts to the space station – a service SpaceX has been providing commercially for NASA since 2020.

Boeing’s third attempt to launch astronauts into space

Should Boeing’s initial crewed test flight succeed, it could pave the way for regular flights of its Starliner spacecraft to the space station for NASA, challenging SpaceX’s current dominance.

The Starliner will carry NASA astronauts Barry “Batch” Wilmore and Sunita Williams, who will spend approximately a week aboard the space station before returning to Earth and landing at White Sands Missile Range in New Mexico.

Starliner’s most recent launch attempt was halted on Saturday with less than four minutes to go due to an automatic abort triggered by a computer controlling the Atlas V rocket, created by United Launch Alliance, a collaboration between Boeing and Lockheed Martin.

SpaceX’s Starship test flight on Thursday aims to demonstrate technologies critical for future moon missions.

Starship, the most powerful rocket ever developed and designed to be fully reusable, is expected to play a vital role in NASA’s plans to send astronauts back to the Moon. Additionally, SpaceX intends to use Starship for eventual missions to Mars.

NASA is also working on its own Space Launch System megarocket and Orion spacecraft for moon missions, part of the Artemis program which envisions establishing a base camp on the moon’s surface before exploring Mars.

Tomorrow’s SpaceX Live Stream: Starship Launch 4 Date, Time, and Viewing Information

SpaceX’s giant Starship rocket was deployed on the launch pad at StarBase, the company’s facility in South Texas, in June 2024 ahead of a planned test flight.

SpaceX is getting ready Starship. The most powerful rocket ever built is gearing up for its next test launch. Here’s everything you need to know.

What time is the launch scheduled?

The launch is expected to take place in the next week or so, but SpaceX has said it could take place as soon as June 5, pending regulatory approval. Each flight must be approved by the US Federal Aviation Administration.

Other signs point to the same day. Judge Eddie Trevino of Cameron County, Texas, home to SpaceX’s Starbase launch site, said: Nearby roads are closed. It will be carried out at the beginning of June. This precautionary measure is usually taken during launches, but it may also be relevant for some of the ground tests.

However, Treviño explicitly states in official documents that these closures are for “flight testing,” and establishes a 14-hour closure period from midnight to 2 p.m. local time on June 5. The documents also state that alternative closures of the same duration could be scheduled on June 6 and 7, if the company so desires.

How can I watch the Starship launch?

SpaceX has announced that a live webcast will begin approximately 30 minutes before launch.

Where is Starship going?

The fourth test flight will focus on returning Starship from orbit and conducting a mock landing of both the Starship and the Super Heavy first stage booster. Because landings on ground are currently deemed too risky, both vehicles will make a “soft splashdown” in the ocean, using their engines to slow their descent and line up, as if they were landing on a base, to gently touch down on the water. The first stage booster is scheduled to splash down in the Gulf of Mexico, not far from the launch site, about seven minutes after liftoff, while Starship aims to splash down in the Indian Ocean about an hour later.

What has happened in Starship launches so far?

All three Starship launches have ended in explosions, which was expected as part of SpaceX’s “fail fast, learn fast” strategy.

During the first launch on April 20 last year, three of the first stage’s three engines (out of a total of 33) failed to ignite. Several more subsequently failed during the flight. The rocket then spun out of control and its self-destruct safety mechanism was activated. The entire flight lasted about three minutes, reaching a maximum altitude of 39 kilometers.

Starship’s second launch was on November 18. This time, all 33 engines were working, and the rocket flew far enough for the first and second stages to separate. But as the first stage rotated to begin its deceleration and landing procedure, it exploded. The second stage continued on smoothly to an altitude of about 90 miles, passing the Kármán line, which marks the beginning of the universe. But it was destroyed by a safety device after it stopped transmitting data before completing an orbit or returning to Earth.

SpaceX’s third Starship test flight, on March 14, was at least partially successful, as it reached space, performed a fuel transfer test, and flew farther and faster than ever before. However, it lost attitude control during the flight and failed to make the planned soft landing. Nevertheless, it achieved several important milestones, including Starship’s first atmospheric reentry from space, the first opening and closing of Starship’s payload door in space, and a successful demonstration of fuel transfer, which is key for future NASA Artemis missions to the Moon.

What would happen if this launch were to fail?

The chances of Starship completing its mission perfectly are slim, so it’s likely to fail in some way. But failure will provide data and experience that can be used to improve the design and process for the fifth launch. SpaceX has shown it can iterate quickly and make great strides with each launch.

The harm of toxic positivity: How relentless optimism can negatively impact your health and mental wellbeing

Having a positive mindset can have unexpected results

DEEPOL (Plain Picture/photo by Anja Weber Dekker)

Do you suffer from low self-esteem? If so, you may have been told to repeat phrases like, “I am worthy of love, I am worthy of love, I am worthy of love.” Repeating positive statements like these is called self-affirmation, and it's said to boost a person's mood and sense of worth. Sounds incredible, right? Well, it is. When psychologists tested the effectiveness of this mantra, it backfired. Participants who started out with low self-esteem ended up feeling worse. The problem was, they simply didn't believe what they were being told.

We know that a positive attitude is good for your health, and that the right mindset can really impact your health and happiness. But it turns out that too much of a good thing can be bad. What psychologists who study self-esteem have discovered is an example of “toxic positivity” – the idea that forcing yourself to interpret your experiences in an optimistic way and suppressing negative emotions can actually do you harm. The term has become something of a buzzword in both academia and pop culture. And yet, the messages that “happiness is a choice” and “positivity is a mindset” are rampant.

What is needed is a return to balance. It is not enough to say that excessive positivity is harmful; we need to know when, why and for whom it is harmful. Fortunately, there is a growing body of research addressing these questions. …

Why You (and Everyone Else) Will Be Wearing a Third Thumb Soon

We are on the brink of having a third thumb, thanks to a revolutionary prosthetic limb being tested in the UK by researchers at University College London. This robotic prosthetic limb for the hand aims to extend human capabilities by allowing users to better grasp and hold objects.

The Third Thumb is a 3D printed wearable that sits on the hand opposite the real thumb and is controlled by wireless sensors attached to the foot. Pressure sensors under the toes control the movement of the thumb, enabling users to lift and hold objects with it.

Recent studies have shown that users can quickly learn to control the extra thumb, with almost all participants being able to use it immediately. Regardless of age, gender, or background, most individuals were able to complete tasks with the thumb, showcasing its potential for widespread application.

While the need for a third thumb may seem unnecessary at first, it has the potential to assist in various tasks, from everyday activities like carrying shopping bags and using a phone to more specialized tasks for musicians, laborers, and surgeons.

The designer of The Third Thumb, Dani Claude, sees it as an extension of the body rather than a replacement limb, emphasizing its assistive nature. While availability to the public may still be some time away, the potential applications for this innovative prosthetic are vast.

Whether it’s holding limes, assisting in surgical procedures, or enhancing musical abilities, the Third Thumb could revolutionize the way we interact with the world around us. Stay tuned for further developments on this cutting-edge prosthetic technology.

New discovery shows scimitar-toothed cat Homotherium found in new locations

Paleontologists from the University of Texas at Austin and other institutions have discovered fragments of the jaw of a feline with scimitar teeth. Homotherium McFaddin Beach, Texas. Homotherium from the continental shelf of the Gulf of Mexico. The topography may have formed a broad subtropical gulf coastal corridor that facilitated the dispersal of Neotropical species along the coast between Texas and Florida. The associated fauna at McFaddin Beach includes Neotropical mammals common to South Texas and Florida, Homotherium It was a type of animal that lived in the Gulf Coast Corridor during the Late Pleistocene.

Homotherium It is an extinct genus of scimitar-toothed cat that lived in the Americas, Eurasia, and Africa during the Pliocene and Pleistocene epochs, from about 4 million to 12,000 years ago.

These animals are large, sturdy cats about the size of a jaguar, with elongated faces, long, slender front legs, and sloping backs that end in short, cropped tails.

Their serrated canines were covered with large gum tissue, similar to that of modern domestic dogs.

Their fossils have been found in several areas of Texas, but the newly discovered remains show for the first time that the big cats roamed the now-submerged continental shelf between Texas and Florida.

“This region was a neotropical corridor,” said John Moretti, a doctoral student at the University of Texas at Austin, and his colleagues.

“Animals that couldn't move any further north, such as capybaras and giant armadillos, used these moist grasslands to migrate from Mexico to Texas and Florida.”

In this fossil specimen Homotherium Moretti's research otherstwo teeth are visible at the bottom: an incisor and the tip of a partially evolved canine. Scale bar – 1 cm. Image courtesy of Sam Houston State University.

The fossils studied by the team were discovered more than 60 years ago. McFaddin BeachIt was written by Professor Russell Long of Lamar University, south of Beaumont.

“The fossil appears to consist of a few exposed teeth in a rugged, rounded rock that appears slightly damaged after being submerged and tumbling on the bottom of the Gulf of Mexico for thousands of years before washing up on the shore,” the researchers said.

“But when we X-rayed the fossil, we found more than met the eye: hidden canines that had not yet erupted from the jawbone.”

“That was the information we needed to identify the fossils as belonging to a specific organism. HomotheriumIt is a genus of large cats that roamed large areas of the Earth for millions of years.”

“This cat wasn't fully developed when it died, so its characteristic sabre-shaped canines hadn't fallen out of place. The teeth were still nestled inside the jaw, protecting them from the environment.”

“If the sabre teeth had been fully developed and in their adult form, rather than during the awkward period of their mid-teens, they would have broken right away,” Moretti said.

“It wouldn't have been there and it couldn't have been used as evidence.”

“The discovery Homotherium “Studying the animals that lived along this corridor gives scientists a glimpse into the local ecosystem during the Late Pleistocene,” he added.

“These large carnivores, like cats, helped shape the wider animal community, suppressing prey populations and impacting local biodiversity.”

AI Used to Create Tom Cruise Deepfake Video Targeting Paris Olympics for Russia

According to a new report from Microsoft, Russia is engaging in a disinformation campaign targeting the Paris Olympics. This includes the use of a deepfake video featuring Tom Cruise as the narrator of a critical documentary about the organization behind the games. You can read the full report on Microsoft’s website.

Microsoft revealed that a network of pro-Russian groups is conducting a “malign influence campaign” against France, President Emmanuel Macron, the International Olympic Committee (IOC), and the upcoming games in Paris. Despite Russia’s ban from the 2024 Olympics, a few Russian athletes may still participate as neutrals.

One of the tactics used by the disinformation campaign was a fake video of Tom Cruise on Telegram titled “Olympics Has Fallen.” The video, a parody of the movie “Olympus Has Fallen,” falsely claimed to be a Netflix production, featured a fake Cruise voice, and criticized the IOC. Microsoft deemed this video to be a more sophisticated creation compared to typical influence campaigns. You can access the full report released on Monday for more information.

The fake video was attributed to a Kremlin-linked group called Storm1679, known for its history of deceiving US actors. Storm1679 has been spreading fear through various videos about potential violence during the Olympics, alongside fake news broadcasts impersonating Euronews and France 24 to instill false narratives about the event.

Social media accounts associated with Storm 1679 have also posted images of graffiti in Paris threatening violence against Israelis attending the Olympics. Microsoft reported that these images were likely digitally generated rather than physically present.

Russia has a history of trying to disrupt Olympic events, with strategies dating back to the Soviet Union’s boycott of the 1984 Los Angeles Games. Another Russian group, Storm-1099 or “Doppelganger,” has launched a fake French news site spreading allegations of corruption at the IOC and potential violence in Paris.

Microsoft warned that Russia’s disinformation efforts might expand to other languages and involve the use of automated accounts and generative AI systems to create convincing fake content. This mirrors similar Chinese attempts to spread disinformation using AI-generated materials, as detailed in a previous report by Microsoft.

Review of Sonos Ace: High-quality noise-canceling headphones that are definitely worth the wait

TWi-Fi hi-fi maker Sonos has finally released its long-awaited first headphones, the Ace, which combine the best elements of products from Bose, Apple, and other high-end rivals with premium comfort, sleek style, and a killer party trick for owners of the company’s soundbars.

These high-tech noise-canceling headphones are priced at £449 (€499/$449/AU$699), putting them at the top of the market alongside the Bose QuietComfort Ultra, Sennheiser Momentum 4, and Apple AirPods Max.

The Ace has a pleasantly sleek, unobtrusive design, with plush, slim earcups that don’t protrude too much from the sides of your head, and the headband has two types of foam, with a softer peak that, like the Sennheiser, relieves pressure on the ridge at the top of your skull.




The Ace comes in black or soft white, with a subtle logo on one ear cup that’s only visible in certain lighting. Photo: Samuel Gibbs/The Guardian

The hidden hinge allows for plenty of adjustability while preventing your hair from getting caught in the mechanism, just like the AirPods Max. They’re very comfortable for extended listening sessions and stay in place when you move around without squeezing your head too tightly.

The left earcup houses the power button and USB-C port for charging and wired listening using USB or the included USB-C to 3.5mm cable, while the right earcup has the noise-canceling control button and a nice slide button for volume and playback controls.

The battery lasted a few hours longer than the rated 30 hours when tested over Bluetooth with noise cancellation enabled, and about 14.5 hours when connected to the Arc soundbar, which is plenty for most uses. It takes about three hours to fully charge and can be quickly charged to 10% in just three minutes for up to three hours of playback.

The lack of influence of Facebook on the UK general election | Technology

yes
Have you ever heard the story about a drunk man looking for his keys under a streetlight? After pacing back and forth for a while and rummaging through the floor, his friend asks him where he thinks he dropped his keys. He points to a dark spot across the street. “Then why don’t you look there?” his friend asks. He shrugs. “Because that’s where the light is.” It’s a good joke. Everyone laughs.

Let’s talk about online political advertising.

“Microtargeting” doesn’t exist anymore, explains The Guardian’s Jim Waterson.

Don’t expect to see Cambridge Analytica-style micro-targeting of political ads using personal information in this general election. The tactic is now seen by many as ineffective “bait” and is increasingly being blocked by social media platforms. Digital strategist Tom Edmonds said Facebook has banned political campaigns from using many of the tactics used in past elections. “If you run a campaign to 500 people, you’re not getting a ton of revenue, you’re just getting a ton of harassment,” he said.

Microtargeting was feared because of its potential negative effects on democracy — if you can target 1,000 different messages to 1,000 different demographics, the very notion of a single national conversation begins to break down — but in reality, microtargeting never really worked.

After all, the biggest competitor for a company like Cambridge Analytica was Facebook itself: the social network’s advertising tools make it less worthwhile to spend billions creating profiles and microtargeting individual voters when you can leave all the targeting decisions to Facebook itself. The social network allows advertisers to set “performance objectives.” [like sales, clicks, or signups]You set a spending limit and then you just sit back and wait for the company to do whatever it takes to maximize your profits. The company will also choose the best combination of words and images to increase your chances of success.

But Facebook can only help you so much. For example, if you’re creating ads for a particular candidate, who should you focus your time and money on? Those who are likely to win, or those who are sure to lose? If you answered the latter, you’d be better off working for the Conservative Party. From our article:

The strategy, known within the party as the “80/20” approach, involves concentrating all of its spending on the 80 seats it is most likely to lose in 2019 and the 20 seats it is most likely to gain.

Facebook’s ad spending reports show the party is pouring money into exactly these constituencies: Since January, more than half of the party’s spending on the social network has been directed to the 80 closest constituencies or those not held by the party at all.

A conference staff member speaks in front of Facebook’s demo booth at F8, Facebook’s annual developer conference in San Jose, California. Photo: Noah Berger/AP

We began monitoring meta ad spending to see if the reported “80/20 strategy” held up. It’s one thing to propose it two years before an election, but quite another to follow through with it just a month away.

But we also started monitoring Meta’s ad spending because we could. The company keeps a library of all political ads, publishes total spending, and requires residency verification before launching a new ad. This library has received a lot of criticism over the years, but at least it exists. Not only that, but the library has a powerful toolset that allows you to write your own software to query and answer questions more serious than “are there any interesting ads that someone paid for recently?”

But like a drunk person searching for his keys, it’s unlikely that this topic is actually on Facebook. Across large swaths of the country, conversations that once took place on public social networks have migrated to private channels, led by Meta’s WhatsApp. What’s left of Facebook itself is smothered in AI-generated rubbish and disconnected from reality by algorithmic tweaks that highlight “friends and family” content. That trend is doubly pronounced on Meta’s Twitter clone, Threads, which actively and openly downgrades any kind of political content.

Although conversations are growing on TikTok, the platform is difficult to cover: Observer research into digital campaigns has had to focus on the official TikTok feeds of political parties.

TikTok is free; paid advertising by politicians or political parties isn’t allowed. But it won’t be easy. Social media teams will have to work harder to convince the app’s notoriously opaque algorithms to let their content flow organically to users’ phones. The more people who like, share, comment and repost a video, the better the chances. For smaller, more agile parties with smaller budgets, TikTok can feel like it has everything to win: views, engagement and people finally finding out they exist. Creators who know how to do it think Labour is off to a good start.

Election conversations are happening on TikTok — and there’s a lot of it, as the platform’s tightly curated algorithmic feed allows people of all ages to have their own discussions — but it’s nearly impossible to observe from the outside without using brute force techniques like tallying up views of videos tagged “snack.”

Of course, WhatsApp conversations are even worse: with end-to-end encryption and sparse public “channels,” doing data journalism tracking election chats is a dead end.

And then there’s AI. Suspicions remain that the rise of AI systems will have some impact on this election, but here, too, we have to look at where the light is. It’s very clear (and we’ve never really seen it before) that deepfake videos are circulating on Twitter, the platform now known as X. What’s invisible to us is that wavering voters are conversing with ChatGPT to try to decide where to type X, if that’s even happening in the first place.

In the UK, these questions feel largely academic; apart from personality-driven local elections, the final outcome feels more foregone than at any time in my life. But in the US, where voters go to the polls in five months’ time, the same questions will be asked. And the answers may hold the key to which side the coin falls.

So let’s go find them right away.

Parts of California and Arizona to experience triple-digit temperatures this week

By Monday morning, firefighters had built containment lines around three-quarters of the fire.

“The humidity is starting to drop,” Kurth said. “We’re seeing an increase in grass fires.”

He noted that the heat wave that began this week is not unusual for Central California in August, but because it started so quickly, it could become more severe because “people aren’t used to the heat.”

“If a heatwave occurs early in the season, the impact on people could be greater,” he said.

He said high early-season surf could also increase the risk of drowning in the Western mountains, where people often flock to rivers and streams fed by melting snow.

“The water is pretty cold and the currents are strong,” Kurth said. “Please be careful and wear your life jackets.”

The National Oceanic and Atmospheric Administration predicted last month that 2024 will be one of the five warmest years on record and could easily be the hottest year on record.

Last year, a prolonged heatwave hit much of the South and Southwest, causing a sharp rise in deaths.

More than 2,300 people who died in the United States last summer mentioned heat on their death certificates, the highest number in 45 years, according to an Associated Press analysis of Centers for Disease Control and Prevention data.

Heat is the leading cause of weather-related deaths in the United States, but its impact can be obscured in death certificate data because heat often aggravates underlying conditions like heart, respiratory and kidney disease. Researchers at Texas A&M University estimated that heat was responsible for 11,000 deaths last year that would not have occurred otherwise, according to the Associated Press.

A weather pattern, such as a ridge of high pressure that is expected to develop this week, is responsible for many of these deaths.

Temperatures in the Phoenix area topped 110 degrees Fahrenheit every day except one last July, according to data from the National Weather Service. Scientists later concluded that would be “virtually impossible” without the effects of climate change. At least 645 people died from heatstroke in Maricopa County, which includes Phoenix and many of its suburbs, last year, a 52% increase from the previous year.

Nigerian Influencer Uses Satire to Highlight Lack of Promotion of Africa in the West

circleWhen Charity Ekezie first joined TikTok in 2020 and started posting videos from her home in Abuja, Nigeria, she had recently left her job at a radio station. She saw TikTok as a way to stay active and maintain her journalism skills.

Within a few months, she realized from the comments on her posts that some people had no knowledge about Africa. Commenters from the UK, US, and European nations asked her questions like if Africa had mobile phones or access to water.

“Wait a minute, are you serious?” Ekezie thought at the time. “This is not the Africa I live in. We have telephones and bottled water. I decided to start responding.”

Armed with humor and sarcasm, Ekezie’s witty replies to questions such as “Do they have planes in Africa?” or “Do they have shoes in Africa?” have garnered her over 4.5 million followers globally. Find her on

Answering a question about why Africans can buy mobile phones but not water, she holds a bottle of water in her hands, with more bottles stacked behind her, and explains that every month people gather for a spitting festival. “All the men do a spiritual chant led by the community magician, and all the women and girls take a turn spitting into the drum. After two days, we go for a purification ritual, so we can take the saliva and drink it,” she jokes.

People laughed at the video, which prompted Ekezie to make more videos and get more questions. Some of them were just trolling, but many were serious.

The video has been viewed more than 22 million times so far, but it has also attracted thousands of racist comments. Ekezie said, “The water was brown during that time. I started getting comments like, ‘Oh my god, the water you’re drinking is dirty,’ and people were saying the water is washing me away, that’s why it’s brown and why I’m so black.”

People left monkey emojis. Ekezie said she didn’t always notice the racism. “I didn’t understand it,” she said. “I was aware of the concept of racism, but I’d never been treated in a racist way. It really hurt.”

But she also received a lot of positive feedback from many Africans, some of whom joined in on the joke in the comments section. People from all over Africa responded to the post, which made light of the fact that many people don’t understand that Africa is a continent, not just one country, with flag emojis. “No matter where you’re from, they were united and they got the joke,” Ekezie says. “Some people said, ‘You will singlehandedly unite Africa.’ That was so cool.”


From this experience, Ekezie, who spent part of her childhood in Cameroon, learned that “Africa is not promoted at all in the West and people don’t know anything about us. I thought people read books but apparently that’s not the case. It’s heartbreaking because we are exposed to Western media, music, and culture every day.”

She’s grateful to be able to share her perspective on social media, and her YouTube following has grown so much over the past year that she’s been able to make a living from her posts. “I make videos because people want to see Africa through my lens, so they can see that it’s not this dreary jungle,” she says.

“I’m not saying African countries are perfect,” she adds. “And what country is perfect? ​​But we need to do our best. People need to know that we have our own problems, but we’re also great countries. We have great cultures, great food, great people.”

The Hidden Method Your Dog Uses to Communicate With You

Our dogs have been our companions for thousands of years. Every wag of a tail, flick of an ear, and furrowed brow speaks volumes if you know how to interpret them.

Despite thinking we know our dogs well, research suggests that dogs are actually better than humans at reading body language. To help us understand dog communication better, we sought advice from experts in animal behavior, such as Dr. Zazie Todd. Learn more about the hidden meaning behind your dog’s behavior, from their nose to their tail, ears to paws.


Understanding Dog Facial Expressions

Humans often rely on facial expressions to understand each other, but can we do the same with dogs? Some dogs have very expressive faces, which can help us interpret their emotions. A relaxed jaw and slightly open mouth can be the equivalent of a “smile” in dogs, while a grinning dog may be signaling aggression. It’s important not to anthropomorphize too much, as dogs may have different expressions than humans.

In some cases, what may seem like a “guilty look” from a dog may actually be their fear of getting scolded. Research has shown that dogs may not fully understand their actions but are responding to the owner’s potential reaction. Eye contact and ear positioning can also reveal a lot about a dog’s feelings and intentions.

Signs of Stress in Dogs

While it’s easy to spot when a dog is happy, signs of anxiety or fear can be harder to detect. Yawning, licking lips, and other subtle cues may indicate stress in dogs. Understanding these signals can help prevent misunderstandings and improve communication between you and your pet.

Interpreting Dog Posture

Dog posture can reveal a lot about their emotions. A low, hunched body may indicate fear, while a playful “play bow” posture signals a desire to engage. Observing your dog’s body language can help you understand their intentions and mood better.

Decoding Tail Wagging

Tail wagging is a common form of communication for dogs. A big, loose wag can indicate happiness, while a stiff, vertical tail may signal stress or aggression. Pay attention to the direction of the wag to better understand your dog’s emotions. Research has shown that the direction of the wag can reflect the dog’s mood.

Understanding Vocalizations

Barking and growling are essential forms of vocal communication for dogs. Different sounds can convey various emotions or intentions. Research has shown that dogs can use growls to express their size and feelings honestly in different situations. Understanding your dog’s vocalizations can help you better respond to their needs.

Volcanic Activity on Jupiter’s Moon Io Discovered by Large Binocular Telescope

how to use SHARK-VIS device Using the Large Binocular Telescope on Mount Graham in Arizona, US, astronomers have captured the highest-resolution optical images of Io ever taken by a ground-based telescope. The new images allow the astronomers to confirm that large-scale surface changes are occurring around Pele, one of Io's most well-known volcanoes.

Taken with the SHARK-VIS camera on the Large Binocular Telescope on January 10, 2024, this image is the highest resolution image of Io ever taken by an Earth-based telescope. The image combines three spectral bands: infrared, red, and green to highlight the reddish ring around Pele volcano (below and to the right of the Moon's center) and the white ring around Piran Patera to the right of Pele. Image credit: INAF / Large Binocular Telescope Observatory / Georgia State University / SHARK-VIS@LBT / PIF Pedichini / D. Hope / S. Jefferies / G. Li Causi.

Io is slightly larger than Earth's Moon and is the most volcanically active body in the solar system.

It is the innermost of Jupiter's Galilean moons, which besides Io include Europa, Ganymede and Callisto.

Io is caught in a gravitational tug-of-war between Jupiter, Europa, and Ganymede, and is constantly compressed, causing frictional heat to build up inside it, which is thought to be the cause of sustained and widespread volcanic activity.

By monitoring Io's surface eruptions, planetary scientists hope to gain insight into the thermal movement of material beneath the moon's surface, its internal structure, and ultimately the mechanisms of tidal heating that drive Io's intense volcanic activity.

Io's volcanic activity was first discovered in 1979, when Linda Morabito, an engineer for NASA's Voyager missions, spotted plumes of smoke in one of the images the spacecraft took during its famous Grand Tour of the outer planets.

Since then, countless observations have been made, both from space and from telescopes on Earth, documenting Io's restless nature.

“Io offers a unique opportunity to learn about the powerful eruptions that contributed to shaping the surfaces of the Earth and Moon long ago,” said Dr Al Conrad, an astronomer at the Large Binocular Telescope Observatory.

The new images, taken with the large binocular telescope SHARK-VIS, are so detailed that they enabled the team to identify a major resurfacing event in which the plume deposits around a prominent volcano known as Pele, located near the equator in Io's southern hemisphere, have been covered by eruption deposits from a neighboring volcano, Piran Patera.

A similar series of eruptions was observed by NASA's Galileo spacecraft, which explored the Jovian system from 1995 to 2003.

“We interpret this change as dark lava deposits and white sulfur dioxide deposits from the Piran Patera eruption partially covering Pele's red sulfur-rich plume deposits,” said Dr. Ashley Davis, principal scientist at NASA's Jet Propulsion Laboratory.

“Before SHARK-VIS, it was impossible to observe these resurfacing events from Earth.”

“The visible light images are absolutely stunning,” said Imke de Patter, a professor at the University of California, Berkeley.

“Pele appears to be erupting continuously, spewing plumes of volcanic gases about 300 kilometers above Io's surface, high enough to have been photographed by Voyager, Galileo and Hubble.”

“Gases in the plume erupting from the lava lake freeze and are deposited on the surface as a conspicuous, wide, reddish, sulfur-rich ring.”

“Piran Patera, on the other hand, appears to erupt intermittently, leaving lava surrounded by a white ring of frozen sulfur dioxide.”

“The new images show that the white sediments obscure Pele's reddish sediments, but perhaps only for a short time.”

“Images of Io taken by NASA's Juno spacecraft in April 2024 will show a nearly perfect orange ring, with perhaps a faint hint of red where the Piran deposits were located.”

“It's like a race between Piram and Pele to see how much and how fast each can deposit.”

“Once Piran stops completely, it will be covered again with Pele's red deposits.”

of Investigation result It will be displayed in journal Geophysical Research Letters.

Ancient snake painting holds record as world’s largest rock art

Animal sculptures carved into rocks along the Orinoco River in South America

Philip Riris et al.

The prehistoric rock carvings of giant snakes along the Orinoco River in South America are some of the largest known rock art in the world, some measuring over 40 metres in length.

The Orinoco is one of the world’s largest rivers, and it flows through Venezuela along the border with Colombia. “There is a fantastic record of rock art along the Orinoco, especially on the Venezuelan side,” he said. Jose Oliver at University College London. “Typically, they are paintings found under rocks.”

He said carvings are common at many open-air sites along the river, but not all of them have been officially recorded.

Oliver and his colleagues have made several visits to the coastal areas on both the Colombian and Venezuelan sides of the river since 2015, trying to get a better picture of the river’s rock carvings.

“It wasn’t hard to find new sites,” a team member said. Philip Lillis Professor at Bournemouth University in the UK. “Every time I turned a corner there was always something new.”

Of the 157 rock art sites the team visited, 13 consisted of carvings over four meters in height. “Anything that size is monumental to us,” Lillis says, “meaning they’re often visible from quite a distance, anywhere from 500 meters to a kilometer away.”

Most of the carvings depict humans, mammals, birds, centipedes, scrolls and geometric shapes, but snakes are one of the largest motifs, the largest measuring 132 feet (42 meters) wide. In indigenous Orinoco mythology, anacondas and boa constrictors are highly revered because they are primordial creator beings, Lillis said.

The prominence of rock art along the river suggests that the ancient carvings may have been territorial markers indicating that a particular group lived there, but not necessarily a warning not to trespass. “The carvings were not exclusionary, but rather may have been an inclusive practice shared between communities,” Lillis says.

Pottery excavated in the area, dated to 2,000 years ago, contains motifs similar to those in the carvings, suggesting that the rock art was created 2,000 years ago as well.

The team hopes to find more of these carvings and glean clues about their origin and purpose — for example, many of them are found close to rock shelters containing burial sites, suggesting a possible connection to ancient funerary practices.

“This is valuable research.” Andres Troncoso “This discovery sheds light on rock art in a little-known part of South America and furthers our knowledge of the region,” said researchers from the University of Chile.

“When Westerners think of rock art, they often think of mammoths, cave lions, and other large mammals that inhabit the Pleistocene cave sites of Western Europe,” he said. Patrick Roberts Commenting on the findings, a researcher from the Max Planck Institute for Geoanthropology in Germany said: “However, the giant snake carving studied in this paper is one of the largest single rock art in the world, and was found in the heart of a lowland tropical environment.”

Young stars are surrounded by a disk of gas and dust that gives rise to planets.

If another very bright and massive star is nearby, its light can heat up the young star’s disk and strip it of some of its material.

“Protoplanetary disks made of gas and dust emerge as a result of star formation processes and are the birth sites for planetary systems,” explained ESO astronomer Marie-Rees-Al and her colleagues.

“The evolutionary path of a protoplanetary disk and its ability to form planets depend on the surrounding environment, and we expect disks to undergo rapid changes in the presence of massive stars.”

“In massive clusters close to OB stars, ultraviolet (UV) radiation can cause the disk to photoevaporate externally, significantly reducing its size, mass, and lifetime.”

Astronomers used the MUSE instrument on ESO’s Very Large Telescope to observe 177-341W and 11 other dwarf stars in the Orion Nebula Cluster, about 400 parsecs away from the Sun.

“The stars encroaching on 177-341 W’s disk drop out of the frame after passing the upper right corner,” the researchers said.

“When that radiation collides with the material around the young star, it creates the bright bow-like structures we see in yellow.”

“The tail extending from the star toward the lower left corner is material being dragged away from 177-341 W by a star outside the field of view.”

“The colours displayed in this image represent different elements, including hydrogen, nitrogen, sulphur and oxygen,” the researchers added.

“But this is only a small part of the total data collected by MUSE. MUSE actually takes thousands of images simultaneously in different colors and wavelengths.”

a paper The findings have been published in the journal Astronomy and Astrophysics.

Dr. Fauci Provides Testimony at Contentious Hearing Regarding COVID-19 Origins

Dr. Anthony Fauci faced tough questions from Republican politicians in a recent hearing regarding the lessons learned from the pandemic. This was his first public testimony since leaving government service at the end of 2022.

During the hearing with the House Select Subcommittee on COVID-19, Fauci addressed various allegations made against him, including claims about funding for virus research in China. Some conspiracy theories suggest that this research could have led to the coronavirus leak.

Fauci admitted that the possibility of a lab leak cannot be dismissed entirely, but denied any involvement in concealing information related to it. He emphasized that the origins of the pandemic remain unknown.

Despite the accusations, no evidence linking Fauci to the origins of the coronavirus was presented during the hearing.

Fauci, who served as the director of the National Institute of Allergy and Infectious Diseases, defended his actions during the pandemic and refuted claims of bribing scientists or misleading the public.

Democrats supported Fauci as a dedicated public servant, while some Republicans, like Rep. Marjorie Taylor Greene, called for his prosecution and made unsubstantiated accusations against him.

The hearing also focused on the EcoHealth Alliance’s research activities, with Republicans questioning Fauci’s relationship with the organization and its president, Peter Daszak.

Fauci addressed the concerns raised during the hearing, including allegations about his former aide’s communications and the nature of the research funded by the National Institutes of Health.

Despite facing continued harassment and threats to his life, Fauci remains committed to serving the public and providing accurate information about public health issues.

Hubble directly observes a barred spiral galaxy from a head-on perspective

This new image from the NASA/ESA Hubble Space Telescope shows the barred spiral galaxy NGC 3059 in the constellation Carina.

This Hubble Space Telescope image shows NGC 3059, a barred spiral galaxy about 57 million light-years away in the constellation Carina. Image courtesy of NASA / ESA / Hubble / D. Thilker.

NGC 3059 It is located in the constellation Carina, about 57 million light years away.

Also known as ESO 37-7, IRAS 09496-7341, and LEDA 28298, the galaxy has a diameter of 55,000 light years.

it was discovered It was discovered on February 22, 1835 by British astronomer John Herschel.

This new image of NGC 3059 shows Hubble's Wide Field Camera 3 (WFC3) is present in the ultraviolet, near infrared, and visible light portions of the spectrum.

Six filters were used to sample different wavelengths, and color was generated by assigning a different hue to each monochromatic image associated with an individual filter.

“The data used to create this image was collected by Hubble in May 2024 as part of an observing program studying a large number of galaxies,” Hubble astronomers explained.

“All observations were made using the same range of filters – partially transparent materials that only let certain wavelengths of light through.”

“Filters are widely used in observational astronomy and can be adjusted to let through a very narrow range of light, or a somewhat broader range of light.”

“Narrowband filters are invaluable from a scientific perspective because specific wavelengths of light are associated with specific physical and chemical processes.”

“For example, under certain conditions, hydrogen atoms are known to emit red light with a wavelength of 656.46 nm.”

“Red light of this wavelength H-alpha radiationor “H-alpha radiation.”

“Their presence is extremely useful to astronomers as they serve as indicators of certain physical processes and conditions. For example, they are often a telltale sign that a new star is forming.”

“Thus, narrow-band filters tuned to pass H-alpha radiation can be used to identify regions of the universe where stars are forming.”

For this image of NGC 3059, a narrowband filter called the F657N or H-alpha filter was used.

“F stands for filter and N stands for narrow,” the astronomers said.

“The numbers represent the peak wavelength that the filter passes. 657 is very close to the wavelength of the 656.46 H-alpha line.”

“Data collected using five other filters also contributed to the image, and they are all broadband filters, meaning they let through a wider range of wavelengths of light.”

“This isn't very useful for identifying very specific lines (such as H-alpha), but it still allows us to explore relatively unusual parts of the electromagnetic spectrum.”

“And by integrating the information from multiple filters, we're able to create beautiful images like this.”

Australia unearths remarkably intact fossil skull of extinct colossal bird

Australian paleontologists Genyornis neutoni A species of giant flightless Mihirn that became extinct approximately 45,000 years ago.

This illustration is, Genyornis neutoni Waterside in a wetland or marsh-like environment. The scene itself was inspired by places that exist in southern South Australia today, such as the Coorong and the Narrindjeri region of the Lower Murray River. Genyornis neutoni If this type of environment were widespread across the country, many Genyornis The fossils were found in Lake Carabonna, more than a day’s drive north, which is now a dry salt lake. It was probably much wetter in the past. Image by Jacob C. Blokland.

Genyornis neutoni Belongs to Dromornithidae The Mihirung is a species of flightless bird from Australia that became extinct during the Oligocene and Pleistocene epochs.

Also known as Newton’s Mihirn, this species lived in Australia between 48,000 and 45,000 years ago.

The bird was over two metres tall, weighed 220-240 kilograms, had tiny wings and huge hind legs, and laid a melon-sized egg weighing around 1.5 kilograms.

The only previous known skull of this species was reported in 1913, and it was so badly damaged that very little of the original bone remained, meaning not much could be inferred about the skull.

The well-preserved new specimen was discovered in the dry, salty lake bed of Lake Carabonna, in a remote area of ​​inland South Australia.

As would be expected from such a large bird, its skull was far from ordinary, with an enormous cranium, large upper and lower jaws, and an unusual skull crown.

The upper beak in particular displays a remarkable morphology that distinguishes this bird even from its closest relatives, which are otherwise quite similar.

Genyornis neutoni “It had a high, mobile upper jaw like a parrot, but was shaped more like a goose, with a wide mouth opening, powerful biting force and the roof of its mouth capable of crushing soft plants and fruit,” says American zoologist Dr Phoebe McInerney. Flinders University.

“Skull features also showed undeniable and complex affinities with early-diverging waterfowl lineages, the South American screamer and, more recently, the Australian magpie goose.”

Genyornis “The mysteries within this group have been difficult to unravel, but with this new skull we begin to piece together the puzzle that shows this species is a giant goose.”

“we, Genyornis“For the first time we’ve been able to work out the face of this bird – it’s quite different to other birds but does resemble a goose,” said Dr Trevor Worthy, also from Flinders University.

skull Genyornis neutoniImage courtesy of McInerney others., doi: 10.1080/08912963.2024.2308212.

By assessing the morphology of the skull, the researchers were able to evaluate the muscles and movements of each joint, building a detailed picture of how the head functioned.

“Bone shape and bone structure are in part related to the soft tissues that interact with them, such as muscles and ligaments and their attachment sites and pathways,” said Flinders University researcher Jacob Blokland.

“By using modern birds as a comparison, we can put flesh on fossils and bring them back to life.”

Moreover, paleontologists Genyornis neutoni It has several unusual adaptations to adapt to its aquatic habitat, allowing it to protect its ears and throat from the influx of water when its head is submerged underwater.

These adaptations provide further support that the species was nothing more than a giant prehistoric goose, and may be linked to its extinction as the freshwater bodies of northern South Australia are now mainly salt lakes.

“Thanks to this skull, we Genyornis neutoni “We now have a much better understanding of these birds, which once roamed widely across the Australian outback, and the reasons for their eventual extinction,” the researchers concluded.

Ancient geese reached the height of three meters and weighed as much as a cow

Artistic reconstruction of Genyornis newtoni, an ancient relative of the goose

Illustration by Jacob C. Blokland

Australia's prehistoric ptarmigan, once thought to be an ancestor of the emu, was actually the largest goose that ever lived.

This group was reclassified based on analysis going back 45,000 years. Genyornis neutoni The skull was found in the fossil deposits of Lake Carabonna in the South Australian desert.

The newly discovered skull is the first of the extinct species to be discovered since 1913, and the only one well-preserved enough to allow detailed anatomical study. G. Newton He weighed approximately 230 kilograms and was over 2.5 metres tall.

However, its close relativesDromornis stiltoniAt well over three metres tall and weighing up to 600 kilograms, it is not only a contender for the largest bird in history, but also the largest goose ever.

When Thunderbird fossils were first discovered in the 19th century, they were thought to be ancestors of ratites, which include emus, cassowaries and ostriches. Later, some argued that the group, officially called Dromornithiidae, with eight known species, should be classified with land birds, which also include chickens and pheasants.

now, Phoebe McInerney Researchers from Flinders University in Adelaide, Australia, concluded that the Thunderbird is a large waterbird and should be classified as part of the Anseriformes, the same group as geese.

The team was primarily convinced by the anatomy of the beak and skull, including the arrangement of muscles and the deformation of the bones to which they were attached. Genyornis The structure is nearly identical to that of South American screamers, an ancient lineage of waterbirds, and is so complex that it's unlikely it evolved independently, McInerney said.

All of the ptarmigans were herbivores, she says, but they were probably fierce creatures. “They would have been very tough animals,” McInerney says. “They could defend themselves and they would have been quite formidable beasts. They would have had a very low, loud cry.”

Adam Yates Yates, of the Northern Territory Museum and Art Gallery in Australia, said the study supports the claims of his predecessor, Peter Murray, who proposed in the early 1990s that the Thunderbird was a waterbird. “So it's not a shock to me,” Yates said. “But Genyornis It took so long to find the skull, so we're very happy that it has finally been found.”

Many Thunderbird species became extinct before humans arrived in Australia around 65,000 years ago, which is thought to have been due to climate change.G. Newtoni Humans had inhabited the continent for tens of thousands of years, and some researchers speculate that hunting may have also played a role in their extinction.

Creating a New Competitor to EA Sports FC: Exciting News for Gamers from FIFA

TTwo years ago, Electronic Arts’ long and lucrative relationship with FIFA fell apart, leading EA to create a new brand called EA Sports FC for the soccer simulation series. FIFA president Gianni Infantino grumpily declared the search for a new developer, stating, “the only real game that bears the FIFA name will be the best for gamers and soccer fans.” Given EA’s extensive experience in producing mainstream soccer simulations over two decades, the challenge for FIFA to find a competitive studio seemed daunting.

News now surfaces that the world soccer federation has teamed up with 2K Games for a new FIFA game, potentially launching later this year. A tweet from Ghanaian retailer MohPlay claims they have signed a deal with 2K Games, confirming earlier rumors about FIFA’s partnership with 2K.

This collaboration makes sense as 2K has significant experience in sports games like NBA 2K, NFL 2K, WWE 2K, TopSpin 2K, and PGA Tour 2K. Moreover, the PGA license was acquired by 2K after EA’s relationship with them ended a few years ago, showcasing their track record in this space.

However, a new FIFA game this year seems unlikely. Even if 2K were to start immediately in May 2022 when EA’s FIFA relationship ends, they would have only two years to build the team, develop the game, digitize players, motion capture, and model stadiums.

Player reactions vary, with many welcoming competition from EA’s franchise, especially considering Konami’s Pro Evolution Soccer brand’s decline. On the other hand, 2K Games has faced criticism for heavy monetization in its games, particularly in the NBA series where players can buy advantages with real money.

It’s exciting to see a new independent contender emerge in the market, reminiscent of classic soccer games like Sensible Soccer and Kick Off 2, or even early 3D titles. Games like Sociable Soccer are interesting, but the hope for something entirely new, fun, fast, and quirky remains, much like the unique concepts introduced in golf simulation games by What the Golf and Desert Golfing. The future of soccer gaming holds promise for innovation and creativity.

Could the revival of classic soccer game ideas like the ZX Spectrum classic Subbuteo or licensed games by retired pros become a reality? Fans of nostalgic and unconventional soccer games eagerly await what the future holds beyond the realm of multi-million dollar tournament licenses and microtransactions.

A reader named Ants poses an interesting question:

“We often hear that the video game industry is bigger than the movie and music industries, driven by higher unit costs of video games compared to movies or music albums. As a video game journalist, have you come across reports that validate this claim?”

While the argument has some merit, it overlooks important factors. Each video game sale can translate into multiple players, amplifying the financial impact per copy sold. Additionally, the rise of free smartphone games like Candy Crush and Genshin Impact, catering to billions of gamers worldwide, challenges the notion of high unit costs for games. The media’s focus on gaming revenue versus film or music earnings oversimplifies the rich diversity and cultural value of games into a financial lens, lacking depth and nuance.

It’s hoped that the industry coverage will evolve beyond revenue figures towards a more holistic understanding of the gaming landscape, emphasizing creativity, innovation, and cultural significance over financial metrics.

What are the causes of brain fog in patients with long COVID?

The COVID-19 pandemic has had long-lasting impacts on society and the health of millions of Americans who are still experiencing symptoms. Long-haul COVID-19 can result in chronic symptoms lasting for months, including weakness, palpitations, fatigue, headaches, and cognitive impairment. Scientists are still uncertain about the extent to which COVID affects brain function, leading to what is colloquially known as “brain fog.” Forgetfulness.

So, what causes brain fog in long COVID-19 patients? Researchers propose that the dysfunction of specialized cells lining the brain’s blood vessels plays a crucial role. Known as the Blood-Brain Barrier (BBB), this filter prevents toxins, pathogens, and large molecules from entering the brain. It is theorized that a leaky BBB could allow harmful substances to enter, disrupting normal processes and causing brain fog.

To investigate the link between a leaky BBB and COVID-related brain fog, researchers led by Matthew Campbell, PhD, and Colin P. Dougherty, PhD, examined the brains of patients previously infected with COVID. They studied a group of men and women over 18 years old, including 10 COVID survivors and 22 long-haul COVID patients (symptoms lasting more than 12 weeks), with 11 experiencing brain fog and 11 without it.

Using high-resolution MRI, the team measured BBB permeability by injecting a contrast agent into the patients’ blood to track blood flow through the BBB and into the brain. Patients with brain fog showed higher leakage rates compared to those without brain fog, suggesting a link between BBB dysfunction and persistent brain fog.

Further analysis revealed that patients with long COVID and brain fog had elevated levels of inflammatory markers in their blood, indicating brain inflammation potentially caused by a leaky BBB. The team also observed higher levels of a cell-signaling protein associated with chronic fatigue syndrome in patients with brain fog.

Investigating the immune system’s role in brain inflammation during long COVID, researchers examined gene activity in white blood cells. White blood cells from long COVID patients with brain fog showed significantly more active genes related to sustaining the immune response, suggesting ongoing inflammation causing BBB dysfunction and brain fog.

Lab experiments with brain cells exposed to patient blood samples further supported the link between inflammation, BBB dysfunction, and brain fog. Additionally, direct exposure of brain cells to COVID virus proteins resulted in increased inflammatory gene activity.

In conclusion, researchers found that BBB dysfunction during long COVID leads to chronic inflammation, contributing to brain fog. This insight may aid in understanding other long-term COVID effects and could guide future research on restoring BBB function to treat long COVID patients.

China’s Chang’e-6 spacecraft has successfully landed on the far side of the moon and has begun taking lunar rock samples from that area for the first time.

After orbiting the Moon for three weeks, the probe landed on a relatively flat area of Apollo Crater within the South Pole-Aitken impact basin at 6:23 a.m. Beijing time on June 2.

The landing sequence was largely autonomous, as the far side of the moon has no direct communications link with Earth, but engineers were able to monitor the situation and send instructions using the Queqiao-2 relay satellite, which was launched in March this year and is currently in lunar orbit.

Once the lander and its attached ascent module separated from the orbital portion of the spacecraft, its engines began a controlled descent, using obstacle avoidance systems and cameras to detect rocks and stones and select a smooth landing area. About 100 meters above the lunar surface, laser scanners selected the final location, after which the engines were shut down and the craft made a cushioned landing.

The lander is currently collecting samples, using a robotic scoop to collect surface material and a drill to extract rocks from about two metres underground, in a process that will take 14 hours over two days, according to the China National Space Administration.

The collected samples will be loaded onto an ascent vehicle and sent through the lunar exosphere to the orbiter module, which will then return to Earth and release the sample-laden re-entry capsule on June 25, which will land at Siziwang Banner in Inner Mongolia.

Wax Heads: A Videogame Bringing High Fidelity to Life in a Record Store

pictureEvery time I experience a breakup, I am drawn to revisit the 2000s classic, High Fidelity. The film follows John Cusack’s character as he nostalgically lists the top 10 worst breakups in his life, each accompanied by a fitting soundtrack. Rather than focusing on Cusack’s glamorous ex-partners, the film revolves around his record store, Championship Vinyl, a haven for lost souls in Chicago.

This DIY community spirit is echoed in Wax Heads, a narrative game centered around running a struggling record store. Described as a “cozy punk life sim,” the game captures the essence of High Fidelity as players navigate the chaos of their first shift at Repeater Records, a fictional store.

The genome of a new fern species from New Caledonia is the largest among all organisms

Tumecipteris oblancorata is a rare fern species known as the wolf lark, found in New Caledonia, a French overseas territory in the southwest Pacific Ocean. It has recently broken the world record with its genome size of 160.45 billion base pairs (Gbp), challenging current understanding and paving the way for further exploration of genome gigantism.

Tomesypteris is a small and relatively understudied genus consisting of 15 species, mostly found in Oceania and some Pacific islands.

Scientists have previously estimated the genome sizes of two Tomesypteris species – Tumecipteris tannensis and Tomesypteris obliqua – with large genomes of 73.19 Gbp and 147.29 Gbp, respectively.

In 2023, Dr. Jaume Pellicer and his colleagues from the Royal Botanic Gardens, Kew, traveled to New Caledonia to analyze the genome size of Tumecipteris oblancorata.

The analysis revealed a record-breaking genome size of 160.45 Gbp for Tumecipteris oblancorata, also known as Tumecipteris truncata, surpassing the genome size of the Japanese flower plant species Paris Japonica (148.89 Gbp). For comparison, the human genome contains approximately 3.1 Gbp across 23 chromosomes.

Tomesypteris is a unique fern genus whose ancestors date back around 350 million years, characterized by primarily being epiphytes with a distribution limited to Oceania and a few Pacific islands.

Dr. Ilia Reich of the Royal Botanic Gardens, Kew, expressed surprise at the world record held by the inconspicuous Tumecipteris oblancorata, highlighting the diversity of plants at the DNA level and their importance in Earth’s biodiversity.

The team’s findings were published in the journal iScience.

Paris Olympics to showcase city’s shift towards reducing air pollution by limiting car usage.

Paris, the host city for the 2024 Summer Olympics, has undergone a significant transformation in recent years. The city has made efforts to become greener by reducing its reliance on cars, setting an example for cities around the world.

Under the leadership of Mayor Anne Hidalgo, Paris has enacted several changes to promote sustainability. Over 100 roads have been closed to automobiles, parking fees have tripled, SUVs have been restricted, around 50,000 parking spaces have been removed, and over 1,300 kilometers of bike lanes have been built.

These efforts have resulted in a 40% reduction in air pollution, according to city officials. Hidalgo expressed that Paris would end its dependency on cars through disruptive changes.

Although European cities like Paris have been leading the way in reducing car use, similar reforms in the U.S. have been slow to materialize. The American infrastructure has historically been built around cars, making it challenging to transition to alternative modes of transportation.

The environmental reforms in Paris have garnered support from residents like Louise Kraustl, who believes that fewer cars and more walking and cycling make the city safer and less polluted. Inspired by the concept of the “15-minute city,” Paris aims to create pedestrian and bike-friendly neighborhoods where daily necessities are within easy reach.

While some cities in the U.S. have made progress in promoting biking and public transport, car dependency remains prevalent. Despite the challenges, experts emphasize the importance of reducing transportation emissions to combat climate change and improve air quality.

Paris’ efforts to prioritize sustainable urban planning serve as a model for other cities to follow. As cities worldwide grapple with the effects of climate change, the need for transportation reform becomes increasingly urgent.

The upcoming elections in Paris will be crucial in determining the city’s continued commitment to reducing car use and combating climate change.

How health trackers may be hindering your journey to optimal health | Life & Style

ohOne thing after another happened, and I was lying shirtless on the couch, with a wrinkled nose as a cardiologist explained that everything was fine, but that my heart was a little… weird. I can’t remember the exact words, but it was probably just above “quirky,” but not quite weird. He was looking at something else entirely, and had noticed that the valves at the top of my heart were a little weird. It had absolutely nothing to do with why I’d come here, and was unlikely to affect my future health in any way, he said. But now that he’d seen it, he thought it best to tell me. I asked if it was good to know, and he shrugged. “Sometimes?” he said vaguely. “It’s complicated.”

At home, I paid more attention than usual to my heartbeat, listening for any unusual sounds. A few months later, when I experienced what turned out to be indigestion, I went to the doctor, worried that my valve was about to burst. I had no history of anxiety disorders and had never paid much attention to what was going on inside my body, thinking it was inevitably unfathomable, like anything going on in the vast depths of the ocean. But once this flaw was revealed, I became uncomfortably aware of every moving part, of everything that might go wrong.

When I read Caroline Crampton’s recent detailed study of hypochondria, A body made of glass aptly describes health anxiety disorder as “a bodily illness that exists only in the mind,” and my hand immediately went to my chest. From 18th-century quack medicine to today’s health industry, Crampton traces the rise of drugs and devices promising relief from imagined ailments, such as the Zeebo pill (currently £73 on Amazon), which is promoted as a placebo and “you yourself are the active ingredient,” and plans for technology that can observe every part of our minds and bodies. But, she asks, can we ever know too much? Reading recent criticisms of blood glucose monitoring and the rise of the Zoe app, I thought of Crampton’s book. These are part of a growing trend for personalized diets, but along with other criticisms (such as a lack of evidence about their effectiveness), Professor Partha Carr, the NHS’s national diabetes adviser, told the BBC that using a continuous glucose monitor (designed for diabetics) for no health reason can make people obsessed with the numbers and, in some cases, “can lead to eating disorders.”

These are apps for “worried people” – healthy people who worry about their health – a growing market at a time when new technology and the old internet are stoking anxiety by providing vast amounts of knowledge to anyone with Wi-Fi. It’s a successful business model, in that they’re both apps for anxious people and apps that create anxious people. Parents are especially susceptible to marketing, with health anxieties projected onto their children. This month’s New YorkerJia Tolentino detailed her efforts to hide her pregnancy from her phone, which meant not buying baby clothes online, not using a period tracker, and not using pregnancy apps. She wanted to avoid being watched, which can be especially hard when you’re encouraged to watch yourself.

In the time it took me to give birth to my two children, there had been an explosion in the technology offered to parents who wanted to both track their pregnancies (through additional ultrasound scans, for example) and keep an eye on their babies (with devices like stuffed toys with hidden cameras or disks that attach to diapers that alert you when your baby rolls over). By 2020, I was surprised at how hard it was to buy, for example, a baby monitor that didn’t include a camera, didn’t require a Wi-Fi connection, and didn’t capture any data. And yet, despite the desire for parenting technology, Tolentino found that it rarely led to better outcomes for babies, but rather exacerbated or, worse, created the anxieties that led to the purchase of these devices. The control that anxious people seek by monitoring their babies and their bodies is an illusion.

This is disturbing, given the growing number of products targeted directly at them. The global wearable technology market (fitness trackers and other devices) is expected to be valued at $61.3 billion in 2022, and to expand significantly by 2030. My 9-year-old’s school friends regularly compare FitBits. But for some, trackers and the like may be doing more harm than good. New Statesman In 2019, a professor of cardiovascular medicine criticized a large study of atrial fibrillation (a common heart rhythm problem) in Apple Watch owners, saying there was no significant health benefit to testing low-risk people, “the kind of people who wear Apple Watches,” and that the study would “inflict substantial distress” on healthy people who would receive notifications about their irregular heartbeat.

Health anxieties have evolved alongside scientific knowledge, with phrases like “cyberchondria” (anxiety heightened by information found online) emerging and some research suggesting that our new loose connection to medical knowledge is making people more anxious rather than lessening it. I resent the way tech companies prey on these anxieties, creating new concerns for profit. I believe it’s true that we can know too much.

Every now and then, a small pain or memory in my chest will raise a chill and I’ll think about my deformed heart, but in those moments I will tell myself sternly that it’s none of my business what’s going on under the sea, or deep inside my body (as long as it doesn’t affect my life).

8 Scientifically Proven Reasons Why Cats Are So Adorable

The study of cats is our favorite field of study (second only to information about dogs). We have compiled our favorite cat facts, from whether your cat truly loves you to how they use their whiskers. Enjoy these 8 fascinating cat facts confirmed by science.

1. Blinking slowly can help you befriend cats

Research has shown that squinting is the most effective way to build trust with a cat.

A study conducted by the Universities of Portsmouth and Sussex revealed that this technique mimics the “slow blink,” also known as a cat smile, and helps establish a bond between humans and cats.

According to Professor Karen McComb from the Department of Psychology at the University of Sussex, who oversaw the study, “As someone who studies animal behavior and has a cat, I’m pleased to be able to show that cats and humans can communicate in this way.”

After a cat has blinked slowly at its owner, the cat is more likely to reciprocate the slow blink than if there is no contact at all.

2. One in 10 pet cats suffers from separation anxiety

More than 1 in 10 pet cats surveyed in a study exhibited behavioral issues when temporarily separated from their owners.

Scientists observed that cats with separation-related problems tended to be from households without females or where multiple females lived. Lack of access to toys and absence of other pets in the home were also associated with similar behavioral issues in cats.

The analysis found that a significant percentage of sampled cats displayed behaviors associated with separation-related issues, including destructive behavior, excessive vocalization, and aggression.

3. Your cat really loves you

While food may have initially brought humans and cats together, cats have shown deep affection towards their human companions over time.

Recent studies indicate that cats exhibit behaviors similar to “secure attachment” seen in dogs, suggesting a strong bond between cats and their owners.

Cats exhibit behaviors beyond seeking food, indicating a deeper bond with their owners.

4. Cats can tell when a thunderstorm is approaching

Cats, along with other animals, have heightened senses that allow them to detect impending storms before their owners.

Your cat may sense changes in air pressure, smell rain, or hear distant thunder, alerting them to an oncoming storm.

5. Cats love boxes for their comfort

Cats seek out cozy hiding spots, such as boxes, for security and comfort, especially when sleeping.

Cats prefer warm environments and will utilize boxes for warmth and a sense of security.

6. Domestic cats impact local wildlife

Studies have shown that domestic cats contribute significantly to the decline of local wildlife populations.

Domestic cats have a concentrated impact on local prey due to their small home ranges, causing significant harm to bird and small mammal populations.

7. Cats cannot thrive on a vegan diet

Cats are obligate carnivores and require specific nutrients found only in meat sources, making a vegan diet unsuitable for cats.

Feeding cats a vegan diet can lead to severe health issues, such as blindness and heart failure, due to the lack of essential amino acids like taurine.

8. Cat whiskers are essential for hunting

Cat whiskers play a crucial role in hunting, providing sensory information to help cats navigate and hunt effectively.

Whiskers help cats judge distances, detect prey, and regulate movement, making them efficient hunters.

NASA astronauts forced to cancel first launch with Boeing again

NASA and Boeing have had to once again cancel the first crewed launch of Boeing’s Starliner spacecraft.

Boeing’s Starliner spacecraft was set to take off from Cape Canaveral Space Station in Florida at 12:25 p.m. ET on Saturday, carrying NASA astronauts Barry “Batch” Wilmore and Sunita Williams to the International Space Station, marking the spacecraft’s inaugural crewed test flight.

Unfortunately, the launch attempt was aborted with just minutes remaining in the countdown, adding to Boeing’s challenges after years of delays and cost overruns in its Starliner program.

The crewed test flight by Boeing was a crucial milestone to demonstrate the safe transportation of astronauts to the space station with Starliner. A successful mission could lead to Boeing being authorized by NASA to conduct regular flights to the space station, providing NASA with an alternative to SpaceX’s Crew Dragon spacecraft.

Boeing’s previous launch on May 6 had also been halted with about two hours left in the countdown due to a valve issue on the spacecraft’s Atlas V rocket. Subsequently, a helium leak was found in Starliner’s propulsion system, causing further delays to the crucial test flight.

Although the rocket’s valve was replaced, the helium leak was determined not to pose a risk to the crew or spacecraft. It was not fixed before the scheduled flight on Saturday, as stated by mission controllers in a press conference the previous week.

Both SpaceX and Boeing were involved in NASA’s Commercial Crew Program, launching new spacecraft to transport astronauts to low Earth orbit after the retirement of NASA’s space shuttle fleet more than a decade ago.

However, Boeing has fallen significantly behind SpaceX, which has been conducting crewed missions to the space station for NASA since 2020.

The issue on Saturday was not the first challenge encountered by Starliner. During its initial uncrewed flight in 2019, software problems forced an early termination of the flight before attempting to dock with the space station. Subsequent attempts were delayed due to a fuel valve issue, with a successful uncrewed flight to the space station only achieved in 2022.

Live Nation probes data breach at Ticketmaster’s US division | Cybersecurity Breach

Live Nation Entertainment is currently investigating a data breach at its Ticketmaster division that was discovered on May 20. This breach is the latest in a string of major corporate hacks that have occurred over the past year.

In a filing with the U.S. Securities and Exchange Commission, Live Nation reported finding “unauthorized activity” in a third-party cloud database containing primarily Ticketmaster data and is working with forensic investigators to address the issue.

Reports surfaced last week that a cybercrime group known as ShinyHunters claimed to have stolen user data for over 500 million Ticketmaster customers. However, Live Nation did not mention Shiny Hunters in its SEC filing.

Live Nation has not yet responded to requests for comment regarding the breach.

This breach comes at a time when concert promoters are facing antitrust scrutiny. Live Nation is at the center of this scrutiny as the first target of antitrust lawsuits filed by U.S. and state governments seeking to break up the company for alleged price gouging on concert tickets.

According to Live Nation’s filing, on May 27, a criminal threat actor attempted to sell purported user data from Live Nation on the dark web. The company is actively working to mitigate risks, notify law enforcement, regulators, and users as needed, and ensure the security of personal information.

Despite the breach, Live Nation believes it will not have a significant impact on its operations or finances. The company is evaluating risks and implementing measures to enhance its operations.
