A scientist with a Ph.D. issues tsunami alerts and serves as a Hurricane Hunting Flight Director. Researchers investigate communities that are prone to flooding during storms.
They were part of over 600 workers who were laid off last week by the Trump administration, resulting in around a 5% reduction in the workforce of the National Weather Service and the National Oceanic and Atmospheric Administration (NOAA).
Kayla Besong, a physical scientist at the Tsunami Warning Center, was one of the affected employees. She played a key role in the safety monitoring team, which was reduced from 12 members to 11. She was responsible for programming a system that assessed the risk to the U.S. coastline and issued alerts accordingly.
The layoffs have raised concerns about the impact on public safety programs and the ability to deal with the increasing frequency of weather disasters due to climate change. Last year alone, NOAA recorded a $27 billion disaster that resulted in 568 deaths in the U.S., marking the second-highest death toll since 1980, accounting for inflation.
Meteorologists are facing challenges and criticism, despite their improving accuracy in predicting weather events. The Trump administration’s decision to cut jobs at NOAA has been met with protests and legal challenges. Experts warn that these cuts threaten progress and could hinder crucial scientific advancements.
NOAA has declined to comment on the layoffs, emphasizing its commitment to providing timely information and resources to the public. Former agency officials argue that the cuts jeopardize public safety, especially during weather emergencies.
Congressional Democrats have also opposed the layoffs, citing the impact on public safety and the ability to provide accurate weather forecasts. The cuts have affected essential roles, such as hurricane modeling specialists and flight directors, who play a vital role in predicting and responding to severe weather events.
The reduction in NOAA’s workforce has sparked concerns about the agency’s ability to effectively respond to upcoming weather seasons, potentially putting lives at risk and undermining public safety efforts.
In the quest for clean energy and a shift away from fossil fuels, scientists may have uncovered new sources of power, potentially hidden in our mountains. A team of researchers from Germany has identified a vast reservoir of hydrogen gas, generated by rocks formed millions of years ago, through advanced simulations.
This discovery is significant as hydrogen (H2) as a power source does not emit greenhouse gases into the atmosphere, making it a more sustainable alternative to fossil fuels that contribute to climate change. Additionally, the production of hydrogen results in water instead of harmful emissions. However, the challenge lies in the fact that natural hydrogen production is rare, with the current synthetic production relying on fossil fuels.
The main hurdle in hydrogen production is sourcing it naturally. While geological processes can generate natural hydrogen without the need for fossil fuels, the availability of large accessible reserves remains uncertain. The recent study conducted by German researchers could potentially address this issue.
“We may be on the brink of a new era in natural hydrogen exploration,” said Dr. Frank Zworn, the lead author of the study published in the journal Advances in Science. “This could pave the way for a new natural hydrogen industry.”
Researchers at the GFZ Helmholtz Center for Geosciences in Germany utilized simulations of plate tectonic processes to identify a substantial reserve of natural hydrogen.
Natural hydrogen can be generated through various methods, such as bacterial transformation of organic matter or the splitting of water molecules due to radioactivity in the Earth’s crust. However, one of the most promising natural methods involves a geological process known as “serpentinization,” where rocks from the Earth’s mantle react with water to release H2 gas.
According to researchers, when these hydrogen-rich rocks are situated near the Earth’s surface, they can create potential zones for large-scale hydrogen production via excavation. These rocks are brought closer to the surface through processes such as continental rifting and mountain formation over millions of years.

By analyzing two processes, researchers determined that mountain formation offers ideal conditions for hydrogen generation. The combination of cold environments in mountains and increased water circulation could enhance hydrogen levels significantly. Simulations showed that rocks emerging through mountain formations have 20 times the hydrogen capacity compared to those brought to the surface via continental rifting.
Signs of natural hydrogen production have already been observed in mountainous regions such as the Pyrenees, European Alps, and Balkans. The research team anticipates that their findings will inspire further exploration of natural hydrogen in these areas and other mountainous regions.
Professor Sasha Brune, the head of the geodynamic modeling section at GFZ, emphasized the economic prospects tied to natural hydrogen. He stated, “It is now crucial to delve deeper into the migration pathways of microbial ecosystems that consume hydrogen, both shallow and deep, and to gain a better understanding of where potential hydrogen reservoirs can be formed.”
Personalized mRNA vaccines, including those for pancreatic cancer treatment, are currently in phase 1 of clinical trials. The research was recently published in Nature.
Pancreatic cancer has one of the lowest survival rates among cancer types, with less than 13% of patients surviving beyond five years after diagnosis. The disease is often diagnosed at an advanced stage, with nearly 90% of cases already progressing when detected.
Pancreatic cancer cells have a high tendency to spread rapidly to other parts of the body, usually after the primary tumor has grown large. Symptoms typically only appear in late stages, and there are currently no routine screening methods like mammograms or colonoscopies for this cancer.
Effective treatments for pancreatic cancer are limited, with survival rates remaining around 10% despite the best available therapies. The development of personalized mRNA vaccines for cancer treatment aims to change this narrative.
Before the widespread use of mRNA vaccines for Covid-19, researchers were exploring their potential for cancer treatment. These vaccines work by training the immune system to identify and attack cancer cells, essentially turning the body’s immune response into a cancer-fighting mechanism. Current research is focused on melanoma, colorectal cancer, and other solid tumors.
The success of mRNA cancer vaccines relies on generating a robust response from T cells, a type of immune cell that recognizes and fights off intruders. These T cells need to be durable and capable of detecting and eliminating cancer cells, including those in pancreatic cancer which present unique challenges due to limited mutation targets.
A recent clinical trial evaluated the efficacy of an mRNA vaccine in pancreatic cancer patients who had undergone surgery to remove the tumor. Results showed that the vaccine elicited a response in half of the participants, generating tumor-targeting T cells that persisted for years. This promising outcome underscores the potential of mRNA vaccines in improving outcomes for pancreatic cancer patients.
The study also highlighted the need for further research to determine the long-term impact of these vaccines on patient outcomes. The development of ready-made mRNA vaccines that target common mutations in pancreatic cancer tumors is another area of ongoing investigation, offering a more standardized approach to treatment.
Overall, early findings suggest that mRNA vaccines hold promise in enhancing the body’s immune response against pancreatic cancer, offering hope for improved survival rates and outcomes in the future.
Elon Musk has stated that he will retract a $97 billion offer to purchase the nonprofit organization behind Openai if the makers of ChatGpt agree to abandon plans to convert them into for-profit entities.
“If the board of Openai, Inc is willing to uphold its charitable mission and ensure that any “sales” are conducted without conversions, Musk will withdraw his bid,” he stated on Wednesday. “If not, the nonprofit must be compensated based on the amount paid by the prospective buyer for the assets.”
Earlier this week, Musk and a group of investors made their offer, adding a new twist to the ongoing controversy surrounding the artificial intelligence company he co-founded a decade ago.
Openai is currently operated by a nonprofit board dedicated to its original mission of developing AI “safer and more advanced than humans” for the public good. However, as the business grows, it has announced plans to change its corporate structure formally.
Musk, along with his AI startup Xai and a group of investment firms, seeks control over Openai by transforming the nonprofit into a for-profit subsidiary.
Openai CEO Sam Altman swiftly dismissed the unsolicited offers in a social media post, reiterating at AI’s Paris Summit that the company is not for sale. Openai’s board chairman, Bret Taylor, echoed these sentiments at the event on Wednesday.
Musk and Altman were instrumental in launching Openai in 2015, but had disagreements over leadership, leading to Musk stepping down from the board in 2018 only to rejoin in 2024.
During a video call at the World Government Summit in Dubai, Musk criticized Altman once again, comparing Openai to turning the Amazon rainforest into a timber company. Altman countered that Musk’s legal challenges were influenced by his competing startups.
Musk is currently seeking a California federal judge’s intervention to prevent Openai’s commercial conversions, alleging breach of contract and antitrust violations. While the judge has shown doubt about some of Musk’s arguments, no ruling has been issued yet.
According to a new study from the University of California, Irvine University, white dwarfs are the life of planets that have produced a warmer surface environment than a warmer surface environment formed within a habitable zone or within a habitable zone. It may provide a suitable environment.

This study included the University of California Irvine Astronomer. Aokawa Shield Coworkers compared the climate of the water world with an Earth-like atmosphere composition orbiting in habitable zones of two different types of stars: the white d star and the main sequence K-Dwarf star Kepler-62.
Using a 3D global climate computer model, normally used to study the Earth's environment, they say that despite similar stellar energy distributions, the explanet of the white d star is far more than the Kepler-62 deplanet I discovered it was warm.
“White dwarf stars may emit some heat from residual nuclear activity into the outer layer, but they no longer exhibit fusion at their core,” Dr. Shields said.
“For this reason, we don't take into account much of the ability of these stars to host habitable exoplanets.”
“Our computer simulations suggest that if rocky planets exist in orbit, these planets may have more habitable real estate on their surface than previously thought. ”
The White Dwarf habitable zone is much closer to the stars compared to other star settlements, such as Kepler-62.
The authors emphasized that this would result in a much faster rotation period (10 hours) for the white dwarf exoplanet, and that Kepler 62's exoplanet has a 155-day rotation period.
Both planets can be trapped in synchronous orbits with permanent daysides and permanent nightsides, but the rotation of the super-fast white dwarf planets extends the circulation of clouds around the planet.
The much slower 155-day orbital period of the Kepler-62 planet contributes to large dayside liquid cloud masses.
“Synchronous rotation of exoplanets in habitable zones of normal stars like Kepler 62 creates more cloud covers on Earth's dayside, reflecting incoming radiation away from the Earth's surface. I expect that,'' Dr. Shields said.
“That's usually good for planets orbiting near the inner edge of the star's habitable zone, where you can cool off a bit, rather than losing the ocean in a runaway greenhouse.”
“But for a planet orbiting straight in the middle of a habitable zone, that's not a very good idea.”
“The planet orbiting Kepler-62 has so many clouds that it is covered in clouds, sacrificeing valuable habitable surface area in the process.”
“On the other hand, planets orbiting the white dwarf spin so fast that they hardly have cloudy time during the day, so they retain more heat and work in their advantage.”
Less liquid clouds and the strong greenhouse effect on the Nightside creates a warmer state on the white dwar planet compared to the Kepler-62 planet.
“These results suggest that the once thought to be lifeless, white d star stellar environment could present a new pathway for exoplanet and astrobiology researchers to pursue. I'm doing that,” Dr. Shields said.
“With powerful observational capabilities online to assess exoplanet atmospheres and astrobiology, such as those related to the NASA/ESA/CSA James Webb Space Telescope, we are now studying a whole new class of whole new classes. You can enter a new stage of being. The world around the stars that was previously not announced.”

The male and female genitals provide a clear environment for microorganisms
Artur Plawgo/Getty Images
Sexual partners transfer their unique genital microbiota to one another during sexual intercourse. This can affect forensic investigations of sexual assault.
Brendan Chapman Murdoch University in Perth, Western Australia and his colleagues collected swabs from the genitals of 12 monogamous heterosexual couples and used RNA gene sequences to identify microbial signatures for each participant. Researchers asked couples to refrain from sex for two days to two weeks, and took follow-up samples several hours after sex.
“We found that these genetic signatures from female bacteria can be detected in male partners and vice versa,” Chapman says. As the team infused it, this change in a person's “sexome” could prove useful in criminal investigations, he says.
The amount of transfers varies from couple to couple, and the team found that even the use of condoms completely prevented the movement of the Sensomem from one partner to another. However, one major limitation of the outcome was the significant changes in female sexsomes during the period.
Chapman says there may be long-term homogenization of the microbiota of monogamous couples, but the bacterial population clearly differs between genders.
“The big advantage we have in our penis and vaginal microbiota is that we observe very different types of bacteria in each because there are huge differences in the two environments,” says Chapman. “For example, the penis is primarily a skin-like surface and therefore reflects similarity to the skin microbiota. There are a variety of anaerobic bacteria in the vagina, and the aerobic type in the penis. .”
So many of these bacteria cannot last indefinitely in the opposite environment, he says. “It's like comparing land to sea animals. Some live exclusively in one or the other and die if removed, but they willingly move and last.”
After establishing bacterial movement during sex, the team wants to prove that individual sexsomes are unique, like fingerprints and DNA. “I think every person's Sensomem contains enough diversity and uniqueness, but there's still something to do to demonstrate it with robust enough techniques to meet the forensic challenges. There is,” says Chapman.
If researchers can prove this, it can help investigate sexual assaults, particularly those in which male suspects do not ejaculate, have had vascular resections, or use condoms. “The genetic profile of a bacterial may be able to support or oppose propositions or testimony about what happened in the allegations of sexual assault,” he says. Dennis McNevin At Sydney Institute of Technology, Australia.
In such cases, the standard profile of human DNA is always preferred due to the great power of distinguishing individuals, he says, but sexomes may offer useful alternatives. “Bacterial genetic profiles may one day complement DNA evidence, or may help refer to the perpetrator of a rare sexual assault where DNA profiles are not available,” McNevin says.
A network of airports like Hong Kong International Airport could effectively detect disease outbreaks

A global early warning system for disease outbreaks and future pandemics is possible with minimal surveillance. We test wastewater from just a few of our international flights at just 20 airports around the world.
If passengers fly while infected with bacteria or viruses, traces of these pathogens can be left in the waste, allowing airports to gather from the plane after the flight. “If you go to the airplane toilet, blow your nose and place it in the toilet, some of the genetic material from the pathogen can go. In the wastewater.” Guillaume St-Onge at Northeastern University, Massachusetts.
St-Onge and his colleagues used an A Simulator Called the Global Epidemic and Mobility Model, it analyzes how airport waste monitoring networks can detect new variants of the virus, such as those that cause Covid-19. By testing the model using different numbers and locations at airports, they have been able to provide 20 strategically located “sentinel airports” around the world and are as quickly as a network involving thousands of airports. It has been shown that occurrence can be detected efficiently. The larger network was only 20% faster, but cost more.
To detect new threats from anywhere in the world, your network should include major international airports in cities such as London, Paris, Dubai and Singapore. However, the team also showed how networks containing different airport sets could provide a more targeted detection of disease outbreaks that are likely to occur on a particular continent.
“This modeling study is the first to provide the actual number of sentinel airports needed to support effective global monitoring while optimizing resource use,” he says. jiaying li At the University of Sydney, Australia.
Additionally, airport-based networks provide useful information on disease outbreaks during an epidemic, such as how quickly diseases spread from person to person, and estimating people who may become infected from exposure to a single case. You can also do it, says ST-. Onge.
Such wastewater surveillance provides early warnings for known diseases and could also track new and emerging threats if genome data for bacterial or viral is available. “I don’t think I can look at the wastewater and say, ‘There’s a new pathogen out there.'” Temi Ibitoye At Brown University in Rhode Island. “But when new pathogens are announced, we can look at previous waste data very quickly and say, “Is this present in the sample?” “

There are still some nuances, such as the frequency of ingesting wastewater samples to track different pathogens. Other challenges include knowing the most efficient way to sample wastewater from an aircraft and assessing the actual effectiveness of the system, says Li.
Long-term surveillance programs also require cooperation from airlines and airports, along with consistent funding sources.
Individual airports can hesitate to participate as risks are recognized for business if infectious disease statistics become widely available. Unless a data processing agreement can alleviate such concerns, Trevor Charles At the University of Waterloo, Canada. He emphasized the importance of coordinated international funding to offset “local political considerations.”
However, given President Donald Trump’s launch of the US withdrawal from the organization, even coordination through international organizations such as the World Health Organization is bringing its own political complications, according to Ibitoye He said. Still, such research is “contributed to making it.” [the monitoring network] She says.
eLon Musk and Sam Altman are not exactly best friends. Altman’s pursuit of a for-profit approach for Openai, a company founded in 2015, seems to have irked Musk. Altman’s focus on making money rather than advancing humanity’s interests clashed with Musk’s vision for Openai.
As a result, Musk, who previously attempted to acquire Twitter, has now acquired ownership of an entity called X, which is linked to Openai’s growth.
Musk, characterized by the US government as lean, efficient, and globally influential, made a substantial bid of nearly $100 million for Openai’s nonprofit sector. Musk emphasized the need for Openai to return to its original open-source and safety-focused model. However, this bid was rejected by Altman, who jokingly mentioned that he would buy Twitter for $97.4 billion if necessary.
Musk’s bid was not about enriching investors or inflating corporate valuations, but about steering AI development towards societal benefits. Although the bid to reclaim control of Openai’s nonprofit was significant, the outcome remains uncertain.
The ongoing feud between Musk and Altman may escalate further, especially considering the history of their disagreements. Musk’s bid to take over Openai’s nonprofit could be seen as an attempt to thwart Altman’s for-profit ambitions for the company.

Musk’s bid for Openai’s nonprofit could have multiple interpretations, ranging from a strategic move to a mere publicity stunt. Given Musk’s penchant for unconventional actions, the true motives behind his bid remain uncertain.
There are various theories regarding the significance of the bid, including references to literature and playful numbers. However, the bid’s seriousness cannot be discounted, especially in light of potential political implications.
The bid may also reflect Musk’s attempt to disrupt the status quo and reshape the future trajectory of AI development. The possibility of Musk and Openai merging in the future cannot be ruled out entirely, given the unpredictable nature of the current situation.
WhatsApp recently won a legal battle against NSO Group, an Israeli cyberwareponds manufacturer. Despite this victory, a new threat has emerged from another company, Paragon Solutions, which is also based in Israel, including the United States.
In January, WhatsApp revealed that 90 users, including journalists and civil society members, were targeted by SPYware created by Paragon Solutions last year. This raises concerns about how Paragon’s government clients utilize hacking tools.
Among the targeted individuals were Italian journalist Francesco Cancerato, immigrant support NGO founder Luca Casarini, and Libyan activist Husam El Gomati. University of Toronto researchers, who work closely with WhatsApp, plan to release a technical report on the breach.
Paragon, like NSO Group, provides spyware to government agencies. The spyware, known as Graphite, allows for hacking without the user’s knowledge, granting access to photos and encrypted messages. Paragon claims its use aligns with US policies for national security missions.
Paragon stated a zero-tolerance policy for violations and terminated contracts with Italy after breaching terms. David Kay, a former special rapporteur, described the marketing of such surveillance products as an abuse and a threat to the rule of law.
The issue has relevance in the US, where the Biden administration blacklisted NSO in 2021 due to reports of abuse. A contract between ICE and Paragon was suspended after concerns were raised about spyware use.
Paragon assures compliance with US laws and regulations, following the Biden executive order. The company, now US-owned, has a subsidiary in Virginia. Concerns remain about potential misuse against political opponents.
Experts from Citizen Lab and Amnestytech are vigilant in detecting illegal surveillance in democracies worldwide.
It is not unusual for the Earth’s core to experience changes in its rotational speed and shape over time. However, recent research has revealed some unexpected developments.
Scientists have been debating the reasons behind peculiar alterations in seismic waves caused by earthquakes. One side argues that changes in the rotational speed affect the travel time of the waves, while the other side suggests that alterations in the shape of the inner core are responsible. A new study published in Natural Earth Science by Chinese and US scientists indicates that it could be a combination of both factors.
The study reveals that in 2010, the Earth’s inner core started to rotate faster than other planets, potentially impacting seismic waves with changes near the surface of the core. These waves, similar to X-rays, provide insights into the planet’s interior. The findings are expected to provide more information about the core’s properties and structure.
“These findings present observable changes that offer a clearer understanding of how the inner core evolves over a few years. There could be more surprises in store,” said Professor John Emilio Vidale, the lead author of the study, to BBC Science Focus.
The Earth’s core is almost as hot as the sun’s surface and is located approximately 6,500 km (4,000 miles) below the Earth’s surface, with pressure exceeding that of the deepest ocean depths. Due to these extreme conditions, direct exploration of the core is not feasible.
Scientists rely on seismic waves generated by earthquakes to study the core. By analyzing how these waves travel through different layers of the Earth, including the core, scientists can gain a better understanding of its structure and movement.
In this recent research, the team focused on seismic waves from 121 repeat earthquake pairs in the South Sandwich Islands between 1991 and 2023. By examining changes in the arrival times and waveforms of these signals over decades, the team identified minor shifts in core movement.
These findings revealed interesting trends in the Earth’s inner core. It rotated faster than the mantle and crust for decades before slowing down around 2010. However, some earthquakes showed no significant time shifts, indicating occasional pauses or reversals in rotations.
The study also made secondary findings, suggesting that factors other than rotation might be affecting the inner core. The team believes that viscous transformations near the inner core’s boundary could be influencing its behavior.
While this behavior may appear unstable, further data is needed to confirm its normality and deepen our understanding of how the Earth’s core functions.
According to Vidale, the simplest explanation is that the movement of the outer core initiates rotations in the inner core, readjusting its position over decades. However, the exact mechanisms behind these adjustments remain uncertain.
“The inner core’s movements may not follow a harmonious pattern, as they seem to align with the outer core’s movements,” he explained.
While this study presents intriguing insights into the Earth’s core behavior, it could pave the way for more discoveries in the future. Vidale suggests that further analysis may reveal more about the core’s activity and its potential impact on Earth’s magnetic field and other phenomena.
This could help researchers understand unpredictable occurrences that may affect satellite operations and compass readings, although they may not have a direct impact on daily life.

We all know that climate change is dangerous. In other words, it is attractive to take dramatic measures to work on it. It is placed deeper than before, such as the construction of a nuclear bomb, or deeper on the seabed.
News reporter Alex Wilkins has drawn attention to feedback on this small scheme. That is the idea of Andrew HayberryWho explained his thoughts paper It was released on ARXIV on January 11th. This is an online repository without a pear review.
The Haybalry plan is based on an existing approach called Enhanced Rock -Weathering. Rock -like rocks react with carbon dioxide in the air, slowly removing greenhouse gases, and trapped in the form of minerals. By crushing such rocks into powder, this chemical weather can accelerate and speed up CO.2 Removal. However, even if it is an optimistic estimation, this only supplements a small part of the greenhouse gas emissions.
That is where the nucleus appears. A decent nuclear explosion reduces a large amount of basalt to powder, enabling significant eruption of rock weathering. Hayberry suggests filling at least 3 km nuclear bombs from the seabed of the South Sea. The surrounding rocks restrict explosions and radiation, minimizing the risk of life. However, the explosion will crush enough rock to absorb 30 years of CO.2 Exhaust.
The first hurdle of Haybalry is the size of the necessary bombs. The biggest nuclear explosion was the explosion of TSAR BOMBA, which exploded by the Soviet Union in 1961. There was a yield equivalent to TNT 50 megaton. Hayberry is a device with 81 gigaton yield and hopes to have a bigger explosion of more than 1600 times the emperor Bomba. Such bombs are written in Sole strictly that they should not be taken lightly.
How we build this, and transport it to the infamous windy South Ocean, safely lower it to the seabed, and then send it to the sea floor a few km below. It is left. Hayberry estimates that this effort costs “about $ 10 billion”. But the feedback doesn't know how he came up with the number.
Anyway, no one tells Eron Mask.

In addition to quantum mechanics, Albert Einstein’s special relativity is functioning as the basis of the standard model of particle physics.
In that mind, there is a concept called Lorentz symmetry. The experimental results do not depend on the direction or speed of the experiment in which they were taken.
Special relativity has endured the trials of time. However, some theories, including specific models in string rationale, predict that very high energy does not work with special relativity and experimental observation depends on the direction of space -time experiments.
Lorentz’s remnants of the symmetry destruction can be observed with low -energy, such as the energy of a large hoodron co -rider (LHC), but has not been found on LHC or other colliders despite previous efforts.
In a new study, CMS physicists have searched for Lorentz symmetry on LHC using the top quark pair, the most known basic particles.
“In this case, relying on the direction of the experiment means that the speed at which the top quark pair is generated by the LHC collision in the LHC is different over time,” they said.
“To be more accurate, the average direction of the top quark generated in the center of the LHC proton beam and the center of the CMS experiment also changes because the earth rotates around the axis.”
“As a result, and if there is a priority in space -time, the production rate of the highest pair varies by era.”
“Therefore, finding a deviation from a certain speed will discover the direction of space -time priority.”
The new results of the team based on the LHC’s second execution data consistent with a certain speed. In other words, Lorentz’s symmetry is not broken, and Einstein’s special relativity remains effective.
Researchers have used results to limit the size of the parameters that are predicted to be null when symmetry is maintained.
The obtained restrictions have improved up to 100 times with the previous search results, which were destroyed by Lorentz symmetry in the previous Tevatron accelerator.
“The results will open a way to search for the future in which Lorentz symmetry will be destroyed based on the top quark data from the third run of LHC,” said scientists.
“Open the door to scrutinization of processes including other heavy particles that can only be investigated on LHC, such as Higgs Boson, W and Z Bosons.”

Pope Francis cautioned world leaders at Davos about the potential dangers posed by artificial intelligence on the future of humanity, highlighting concerns about an escalating “crisis of truth.”
He stressed the need for governments and businesses to exercise caution and vigilance in navigating the complexities of AI.
In his written address to the World Economic Forum (WEF) in Switzerland, the Pope pointed out that AI poses a “growing crisis of truth in public life” due to its ability to generate outputs that closely resemble human output, which could lead to ethical dilemmas and questions about societal impacts.
The Pope highlighted that AI has the capacity to learn autonomously, adapt to new circumstances, and provide unforeseen answers, raising crucial ethical and safety concerns that demand human responsibility. Cardinal Peter Turkson, a Vatican official, echoed this sentiment in a statement delivered to Davos delegates.
Having personally encountered AI’s ability to manipulate truth, the Pope has become a subject of AI-generated deepfake images, such as embracing singer Madonna and donning a Balenciaga puffer jacket.

The Pope emphasized that unlike many other human inventions, AI is trained based on human creativity results, often producing artifacts with skill and speed that rival or surpass human capabilities, posing significant concerns about AI’s impact on humanity’s place in the world.
AI dominated discussions at the Davos conference this year, with tech companies showcasing their products along the ski resort’s promenade.
Expectations are high among some participants for AI’s potential. Salesforce chief Marc Benioff predicted that future CEOs will manage both human and digital workers, underscoring the transformative nature of AI in the workplace.
Ruth Porat, Alphabet’s chief investment officer, lauded the potential of AI in improving healthcare outcomes and potentially saving lives.
She highlighted Google’s AlphaFold AI program’s success in predicting the structures of all 200 million proteins on Earth and releasing the results to scientists, a move expected to enhance drug discovery processes.
Last year, Demis Hassabis, co-founder of DeepMind, an AI startup acquired by Google, received the Nobel Prize in Chemistry for his groundbreaking work using AI.
Mr. Porat, a staunch AI advocate, shared his personal experience of battling cancer and emphasized the transformative potential of AI in democratizing healthcare through early detection and access to quality care for all individuals.
If TikTok disappears from the United States, its 170 million American users won’t be the only ones who lose out.
British TikTokers and executives told the Guardian that they would lose a significant portion of their audience after the ban. The video app has become a key entry point into the U.S. for British online video creators who make a living by gaining views and securing sponsored content deals. The ban is scheduled to go into effect on Sunday, leaving a U.S.-sized hole in the global user base.
“In English-speaking markets, many creators have significant U.S. audiences following them,” says Billion Dollar Boy, a UK-based advertising agency that connects creators and influencers with blue-chip advertisers. CEO Thomas Walters said: He added that a ban would be “really sad” for creators who have “built an audience from nothing” on TikTok.
The Guardian spoke to several UK-based creators and one entrepreneur, all of whom said they would be affected by the ban.

Almost half of the users are from the United States. Beech’s 1.7 million viewers On TikTok. He said there were strong relationships between creators and users on both sides of the Atlantic, and that millions of Brits and Americans would miss this kind of digital cultural exchange.
“Seeing that gap in our feeds is going to make a big difference for all of us,” he says.
Beach, who describes her posts as “high energy fashion content”, said sponsored content from brands such as US skincare brand Kiehl’s and Sky TV makes up the bulk of her income. He also has a presence on YouTube Shorts and Instagram, but says he’s noticed that TikTok users “don’t necessarily follow you anywhere else.”
“[A ban] “It’s going to throw people into this diaspora of rediscovering their favorite creators and finding a new home on their platform of choice,” he said.

Fats is a comedian and disability activist who posts comedy, beauty, and lifestyle content. 3 million followers on TikTok. She says the platform’s reach in the U.S. (about a quarter of her followers) is essential to her work.
“TikTok is very important to my career because it allows me to connect with an audience in the United States, where there is a lack of representation for people like me – Black women with dwarfism. “That’s often the case,” she says.
Timbo added that the United States offers creators like her the opportunity to “grow, collaborate, and get noticed on a global stage.”
“It’s not just about the numbers. It’s about the impact I can have and the representation I can give to people who rarely see people like them in the media. Losing that connection is something that I You feel like you’re losing some of your purpose,” she says.
Timbo says the US audience is “key to securing deals, collaborations and global visibility with brands.” Losing TikTok in the US would be a “major setback,” but she is also creating content on Instagram to stay connected with her US followers.
M Wallbank, 25, South Yorkshire
Approximately 40% of Em Wallbank’s audience is from the United States. The South Yorkshire-based creator said it was also thanks to her accent that her comedy skits became a hit across the Atlantic. Wallbank is best known for his posts riffing on Harry Potter characters. TikTok has 1.7 million followers.
“I think part of my popularity is because I’m from the north and my accent is a bit unusual.” [to US users]” she says.
Wallbank, who started posting skits on TikTok in 2022, said the U.S. social media market is a test of the ability for creators like the Kardashians and Nicole Richie to build broad careers.
“People who have careers outside of social media are getting more attention from American audiences,” she says.
Wallbank’s popularity in the US has led her to perform at US fan conventions and create sponsored content with multinational companies such as Disney+ in the UK. She’s concerned about aspiring creators who are using TikTok and its U.S. audience to access creative careers that might otherwise be out of reach.
“Being able to use my background to break into a creative industry is huge,” she says.
Sarah Yuma, 30, London
Uma says her American TikTok audience is essential to the growth of her business, which sells home accessories and hair accessories made from African fabrics.
“It can be difficult to build a business solely relying on a UK audience. It was the US audience that propelled my business during lockdown and took it to the next level.” she says.
Yuma has more than that 3,000 followers on TikToksaid it saw an influx of U.S. customers and followers in 2020 as the Black Lives Matter movement grew in popularity.

If TikTok were to disappear from the U.S., “we would be losing a huge part of our community,” Yuma said. “They helped me design it. It’s a really beautiful community I’ve created.”
She added that if TikTok were to be suspended in the U.S., it would have to rethink how it connects with U.S. audiences.
“We need to rethink our strategies on how to keep them in the community and keep them in touch,” she says. “I don’t want to isolate them. They’re really important to my business.”
Sam Cornforth, 29, London
corn force post fitness comedy sketches He has 460,000 followers, about a quarter of them in the United States. He said income from sponsored content would be protected by the fact that it was working with UK-based brands like Argos.
But he said brands could react negatively to creators losing a significant portion of their audience.
“Brands are paying attention to your entire reach. If you potentially cut 20% to 30% of that, would that impact future opportunities with those brands?” he asked.
Cornforth added that TikTok’s U.S. audience is important in establishing trends that filter down to other platforms. Without that influence, creators may lose the impetus and inspiration for their work.
“This is where the trends come from, which later narrows down to YouTube Shorts and Instagram,” he says.
A stone tablet with a sun motif discovered on the Danish island of Bornholm
Antiquity Publications/John Lee, National Museum of Denmark
Hundreds of mysterious carved “sun stones” excavated in Denmark may have been ritually buried after the sun disappeared in a volcanic eruption around 2900 BC.
A total of 614 stone tablets and fragments inscribed with decorative motifs of the sun and plants have been unearthed in recent years. Basagard West Ruins Located on the island of Bornholm in Denmark. They were discovered in geological formations dating back some 4,900 years, when Neolithic people were farming the region and building enclosures surrounded by earthworks of banks and ditches.
Most of the carved sun stones were found in ditches around these enclosures, which were covered with cobblestones containing pottery shards and other items. This pottery is typical of the Late Funnel Beaker culture, which existed in the area from about 2900 to 2800 BC.
It was originally proposed that the stone carving of the sun was buried to ensure a good harvest. They say the sun was central to early Nordic agricultural culture. Rune Iversen at the University of Copenhagen, Denmark.
“But why did they store all these images at the same time?” Iversen asks. “The last thing they basically did here was deposit these sun stones and cover them with animal bone fragments and all kinds of artifacts and stuff like that. And then it went from trench to trench. You can see it being repeated. So it's some kind of action or event.”
Now he and his colleagues have found the answer. They looked at data from ice cores taken in Greenland and Antarctica and found that high concentrations of sulfate were deposited in the years following volcanic eruptions around 2900 BC.
Researchers say the relative proportions of sulfate deposition in Greenland and Antarctica suggest the eruption was somewhere close to the equator, and its effects appear to have spread over a vast area. . Ash clouds may have blocked out the sun and cooled temperatures for years.
A severe cold period around 2900 B.C. is supported by sources such as preserved wood rings from the Main River Valley in Germany and long-lived rock pine tree rings from the western United States.
This eruption would have had a devastating impact on the Neolithic peoples of northern Europe. “If we don’t have a harvest and the crop is not accepted, we won’t be able to sow anything next year,” Iversen says. “They must have felt quite punished at the time, because endless catastrophe was just going to befall them.”
He and his colleagues say burying the sculptures may have been an attempt to bring back the sun, or a celebration after the skies finally cleared.
say “that's a good explanation” jens winter johansen At the Roskilde Museum in Denmark. “There is no doubt that our staunchly agricultural society must trust the sun.”
Lars Larsson Researchers from Sweden's Lund University asked why, if climate impacts are widespread, evidence of such behavior is only found on Bornholm and not elsewhere in southern Scandinavia. Ta.
That may be because the people there had an abundance of slate, a hard stone with which to carve statues of the sun, whereas much of the rest of southern Scandinavia is mostly clay and has fewer stones suitable for carving. The body, Iversen says. “They may have carved wood or leather from other locations,” he says, but these would not normally have been preserved.
Or it may reflect cultural differences, Johansen says. “These societies are not isolated, but they are more isolated on the islands. That may be why they developed their own customs and culture.”
Tap water in the Los Angeles area could be unavailable for some time due to concerns about damage to infrastructure and chemicals from wildfires, experts say. At least two water authorities have issued warnings about possible contamination from ongoing fires. Experts are worried about the risks to human health from chemicals and pathogens entering the water system, but accurate assessment may take time.
Residents in Pacific Palisades and neighboring communities have been advised to use bottled water for cooking, drinking, and other purposes due to potential contaminants like benzene entering the water system. The Pasadena Department of Water and Power has also instructed residents to switch to bottled water until further notice following concerns about debris impacting the water quality.
Drinking water systems can become contaminated after wildfires, as seen in past incidents in urban areas. Loss of water pressure in the system can be a sign of contamination, triggering careful analysis of the water quality. Environmental engineers are conducting tests in key areas to determine when the water will be safe to drink again.
While there is concern about potential contamination from flame retardants and ash from burnt materials, experts are mainly focused on monitoring benzene and other harmful chemicals due to their carcinogenic properties. Boiling water does not eliminate these chemicals, so the authorities have rescinded the “boil water” advisory. The testing process for dangerous chemicals can take weeks or even months to complete.
In cases of low contamination levels, flushing water pipes may eliminate the hazard, but in severe cases, pipe replacements might be necessary. Contamination around destroyed buildings poses the highest risk in the water distribution system. It is crucial for authorities to thoroughly assess and address the contamination to ensure public safety.

Industrial waste has been reborn as a battery component that can stably store a large amount of electrical charge. Such batteries could serve an important function for the power grid by smoothing out the peaks and valleys of renewable energy.
A redox flow battery (RFB) stores energy as two liquids called an anolyte and a catholyte in a pair of tanks. When these fluids are pumped into a central chamber separated by a thin membrane, they chemically react to generate electrons and generate energy. This process can be reversed to recharge the battery by passing an electric current through the membrane.
Although such batteries are cheap, they also have drawbacks. They are bulky, often as large as shipping containers, and require regular maintenance because they involve moving parts in pumping liquids. It also relies on metals such as lithium and cobalt, which are in short supply.
now, Emily Mahoney and colleagues at Northwestern University in Evanston, Illinois, have discovered a simple process that can turn previously useless industrial waste into useful anolyte. This could potentially replace these rare metals.
Their process converts triphenylphosphine oxide, which is produced during the manufacture of products such as vitamin tablets, to cyclic triphenylphosphine oxide, which is more likely to accumulate negative charges. When used as an anolyte, no loss of effectiveness is observed after 350 charging and draining cycles.
“Using an anolyte with a very negative potential increases the potential across the cell and therefore increases the efficiency of the battery,” Mahoney says. “But often the increased potential comes with stability issues, so it's exciting to have a stable yet highly negative compound.”
Mahoney said RFBs are designed to be safe and high-capacity, so they could potentially be used to store energy from wind and solar power, but their bulk makes them unsuitable for lithium-ion batteries in cars and smartphones. It is unlikely that they will be replaced.
Paleontologists in Uruguay have discovered a large, poorly preserved and incomplete skull of an ancient aquatic reptile called a mesosaurus, along with some accompanying bones. These new specimens suggest gigantism exists in mature mesosaurs that reach more than twice the size of previously reported adult and typical specimens.
Mesosaurs are small to medium-sized aquatic or semi-aquatic amniotes that lived in Gondwana during the Early Permian Period. Image credit: Roman Yevseyev / Graciela Piñeiro.
mesosaurus A group of small aquatic reptiles that lived in South Africa and South America during the Permian Period, approximately 299 to 270 million years ago.
These creatures were the first known aquatic reptiles to return to aquatic life from apparently terrestrial ancestors.
“Mesosaurs are often described as small to medium-sized aquatic amniotes due to their elongated bodies and long tails that exceed the length of the rest of their bodies,” Graciela Pinheiro of the University of the Republic and colleagues. said.
“Additionally, their long-nosed skulls consist of very thin skulls with numerous needle-like marginal teeth.”
“Despite the fragility of some parts of the skull, mesosaur fossils are abundant in the Percarboniferous shales and silt deposits of Gondwana, including preserved bones with articulated skulls. This includes nearly complete skeletons in good condition, as well as partially preserved specimens that still have recognizable soft tissue.
“This exceptional preservation has led to the designation of the Mangrullo Formation in Uruguay and the Illati Formation in Brazil as part of the Conservat Lagerstätten of Gondwana,” they added.
“Furthermore, mesosaur fossils collected from these units include a variety of ontogenetic stages, from fetuses to juveniles to adults.”
“Thus, the ontogeny of mesoosaurs is well documented, with body length ranging from 10 to 12 centimeters (3.9 to 4.7 inches) in hatchlings to 80 to 90 centimeters (2.6 to 3 feet) in young adults. ”
“The average body length of the middle dragon is about 70 cm (2.3 feet),” the researchers said.
“Previous research suggested that mesosaurs were semi-aquatic amniotes, rather than fully aquatic amniotes.”
Mesosaurus ontogenetic cranial series documented from specimens discovered in the Conservato Lagerstätte, Mangrullo Formation, Uruguay. Scale bar – 1 cm. Image credit: Pinheiro others., doi: 10.3390/fossils3010001.
Dr. Pinheiro and his co-authors discovered and studied the largest known mesosaur fossil ever recorded.
The specimen includes two fragmentary skulls, a dorsal vertebrae, a tail fragment, an isolated rib, and several other bones.
They come from the regions of Picada de Cuero and El Baron. Mangrullo formation Located in northern Uruguay.
Paleontologists compared the new fossil to a larger sample of the same bone. Mesosaurus tenuidens.
Their analysis revealed that the size of mesosaurs in the Mangrullo Formation exceeded the typical size distribution previously recorded. Mesosaurus tenuidens.
These individuals were four to five standard deviations larger than average, with skull lengths of 15 to 20 cm (5.9 to 7.9 inches) and total body sizes of 1.5 to 2.5 m (4.9 to 8.2 ft).
“To explore the importance of such large mesoosaurs in the Mangrullo Formation population, we considered the potential effects of Bergmann dominance,” the researchers said.
“This is a study of isolated populations of the same species or different taxa whose body size may have been affected by changes in temperature or food availability, such as competition for nutrients. Although this is an important paleogeographical principle, it does not explain the presence of such large creatures.'' Mesosaurian specimens from the Mangurlo Formation. ”
“We therefore conclude that the large body size variations observed in mesosaurs correspond to their ontogenetic stages and growth patterns,” the researchers said.
“The smaller body size previously recognized may represent a population dominated by early juveniles, subadults, and young adults, and may be due to normal carcass wasting of animals that died from a variety of causes. It may reflect a catastrophic mass mortality event that impedes the increase.”
“The bentonite layers and gypsum crystals found in the Mangrullo Formation are the result of occasional inflows of ash fall onto the lagoon resulting from increased tectonic activity associated with the Pangea Formation.”
“These volcanic events, combined with the gradual drought and associated desertification observed in the Irati-Whitehill Sea, are the main triggers that may explain the extinction of mesosaurs, at least in the Uruguayan region of the Paraná Basin. It is suggested that

Good neighborhoods are defined by the people who reside there. The presence of a helpful individual can enhance the community, while a negative neighbor can detract from its overall quality. The same concept applies to the brain, as revealed in a recent study indicating that brain cells behave like communities. Some cells contribute to a nurturing environment, promoting health and resilience in adjacent cells, while others spread stress and damage like bad neighbors.
Throughout one’s life, the composition of this brain community influences the aging process. Negative relationships can accelerate aging and lead to issues such as memory loss, while a healthy brain community can work collectively to combat aging. Researchers at Stanford University believe that these findings could potentially inform the development of treatments to slow or reverse aging.
Published in the journal Nature, the study identified 17 cells that influence aging positively or negatively. Notably, T cells and neurons were highlighted for their significant impact as bad and good neighbors, respectively. T cells, typically involved in fighting infections, can contribute to inflammation in the brain and hasten aging, while neural stem cells play a vital role in rejuvenation and maintaining a youthful brain.
The researchers conducted gene activity mapping across 2.3 million cells in the mouse brain, constructing a “spatial aging clock” to predict the biological age of individual cells. This innovative approach could lead to new biological discoveries and interventions, such as inhibiting pro-aging factors released by T cells or enhancing the efficacy of neural stem cells.
These findings have implications for understanding diseases like Alzheimer’s and potential strategies to strengthen the brain’s natural repair mechanisms and prevent cognitive decline. The research offers hope for uncovering ways to support brain health and combat aging-related challenges.
○Last Week Tonight, John Oliver investigated the impending ban of TikTok in the United States. TikTok, a popular social media app known for its cooking tutorials and trendy dances, has captured the attention of many users, especially those born after 1985.
With 170 million active users in the U.S., TikTok has a significant following, particularly among young adults. Despite its popularity, the app faces potential extinction as the Senate passed a bill in April giving its Chinese parent company ByteDance an ultimatum to sell TikTok or risk being banned in the U.S. due to national security concerns.
Lawmakers from both parties view TikTok as a threat, with one likening it to a “gun to Americans’ heads.” Despite this, Oliver humorously points out that Congress tends to act differently when faced with literal gun violence as opposed to figurative threats.
Oliver delves into TikTok’s history, highlighting the app’s rapid rise in popularity, especially during the pandemic. He humorously notes that TikTok thrived during lockdowns as people turned to it for entertainment and distraction.
Concerns about TikTok’s ties to China have been ongoing, with President Trump attempting to block the app through an executive order. Despite TikTok’s efforts to distance itself from China, questions remain about the security of user data and potential government influence on the app.
Oliver examines TikTok’s data collection practices and algorithm, pointing out the extensive information the app gathers about its users. He raises alarm about the potential vulnerabilities and privacy risks associated with TikTok’s operations.
While acknowledging concerns about propaganda and censorship on TikTok, Oliver questions the evidence supporting these claims. He suggests that underlying motives, including competition from other tech companies, may be at play in the push to ban TikTok.
Oliver concludes by emphasizing the need for stronger privacy protections in the U.S. and questioning the efficacy of banning TikTok as a solution. He highlights the complex nature of the debate and the lack of clear solutions in addressing the risks associated with data privacy and national security.
DDonald Trump’s resounding victory in the 2024 presidential election can be largely attributed to the unwavering support of the richest man in the world. Elon Musk, in the leading months to the election, fully embraced the MAGA movement, stood up for Trump on a significant podcast, and utilized his influence through X to shape political conversations. A staggering amount of around $120 million was injected into the former president’s campaign by Musk. Now, Trump is expressing his gratitude, mentioning that he intends to appoint Mr. Musk as the “cost reduction secretary.” Musk humorously suggested his interest in leading the Department of Government Efficiency (Doge) to slash government spending by $2 trillion. This move could potentially impact Musk’s companies like Tesla, SpaceX, X, and Neuralink directly through deregulation and policy alterations.
Experts foresee a reciprocal relationship where the Trump administration might ease regulations and redirect federal resources in a manner that favors Musk. This transparent and transactional exchange sets a unique precedent in recent U.S. political history, as noted by Gita Johar, a professor at Columbia Business School. The possibility of quid pro quo benefits for Musk has raised concerns about conflicts of interest.
President Trump: “Bad for electric cars, good for Elon”
Although President Trump has been vocal in his criticism of electric vehicles, Tesla’s fortunes surged under his administration. Tesla’s stock price soared by 13% to reach a 52-week high following the announcement of Trump’s endorsement by the Associated Press. This bolstered Musk’s personal wealth by $26 billion, despite Trump’s public skepticism towards environmentally friendly cars and his plans to revoke Biden’s electric vehicle-related mandates.
However, Trump’s stance on EVs softened after Musk extended his support to him, displaying a shift in policy alignment. The potential reduction in tax credits for EV buyers under the Trump administration could adversely affect emerging EV startups and traditional automakers but benefit Tesla, which heavily relies on these incentives.

Dan Ives, an analyst at Wedbush, highlights Tesla’s advantageous position due to its scale and scope in the EV market, which could provide a competitive edge amidst changing regulatory landscapes. However, the potential implications of Trump’s tariffs on Tesla’s supply chain from China pose significant challenges, especially concerning the production costs and materials sourcing for Tesla’s vehicles.
The Trump administration’s policies could reshape the environment for Musk’s autonomous vehicle ambitions, namely Tesla’s self-driving car rollout, by potentially streamlining regulations and federal approval processes. This could accelerate Tesla’s progress in catching up with more advanced competitors in the autonomous vehicle space.
SpaceX could secure lucrative government contracts for Starlink deployment and Mars missions
SpaceX, Musk’s private space company, stands to benefit substantially from potential government partnerships under the Trump administration. Musk’s alignment with Trump could strengthen SpaceX’s position in securing space contracts, especially with the intensifying competition from other space ventures. The relationship between Musk and Trump could pave the way for SpaceX to capitalize on government contracts for projects like Starlink deployment and Mars missions.
Furthermore, Musk’s engagement with the Trump administration could influence policies favoring SpaceX’s interests, such as with regards to space exploration and satellite internet services. Republican-led initiatives may open doors for SpaceX to expand its services like Starlink, offering new opportunities for government collaboration and funding.
Musk’s push for Mars colonization aligns with Trump’s vision of space exploration and could lead to lucrative government contracts for SpaceX in the realm of interplanetary missions. The collaboration between Musk and Trump on space ventures could mark a new era of space exploration and government partnerships.
Preparing the ground for Musk’s self-driving cars
Musk’s involvement in shaping regulations for self-driving cars, particularly Tesla’s autonomous vehicles, could greatly impact the future of transportation. Trump’s administration may play a pivotal role in streamlining regulations and approval processes for advanced autonomous vehicles, potentially benefiting Tesla’s efforts in the space of self-driving technology.
Experts highlight the importance of regulatory decisions under the Trump administration that could influence Tesla’s autonomous vehicle roadmap, as well as the broader implications for the transportation industry.
Trump’s potential impact on Neuralink and X oversight
Aside from Tesla and SpaceX, Trump’s presidency could affect other Musk-owned ventures like Neuralink and X. Regulatory changes under the Trump administration, particularly at the FDA, could potentially reduce oversight on Neuralink’s brain-computer interface experiments and X’s operations.
Despite concerns about conflicts of interest, Musk’s influence in the Trump administration could shape policies in ways that benefit his businesses. The dynamics of this relationship raise ethical questions about the intersection of business interests and governance in the political landscape.
“The conflict of interest seems pretty strange.”
Elon Musk’s expanding role in American politics and the Trump administration poses unique challenges and opportunities. Musk’s deep pockets and close ties to Trump signal a shift in the traditional power dynamics of politics and business. The potential conflicts of interest inherent in Musk’s involvement in policy decisions underscore the need for greater transparency and accountability in government and corporate relations.
The uncertain future of Musk and Trump’s alliance raises questions about the ethical implications of such relationships and the broader impact on governance and public trust. As Musk continues to navigate the political landscape, his influence and actions will undoubtedly shape the future of technology, business, and politics.
There’s a saying: “Never stay more than 6 feet away from a mouse.” Although I’m here BBC Science Focus, we concluded that this measurement is inaccurate, but may soon become more accurate for those involved in illegal wildlife trade (IWT).
The research team used the anatomical structures of endangered animals such as pangolin scales, elephant ivory, and rhinoceros horns on African giant pouch rats to provide a low-cost detection system to prevent illegal smuggling. I trained myself to be able to distinguish scents.
– Hmmmm – Swarms of rats have been shown to be able to identify these items even when hidden inside other materials, and to remember their smells even after months of no exposure.
undefined
Why rats?
this is not the first timeApopo The Tanzania-based nonprofit organization tasked with conducting this study recognizes the potential of a super rat workforce.
The organization aims to provide low-tech, cost-effective solutions to pressing humanitarian challenges across Africa and has previously developed the HeroRATS technology to detect landmines and the pathogen that causes tuberculosis. I trained the pack.
Dr. IsabelZottofirst co-author of new research Published in frontiers of conservation science, It helped to identify the potential for IWT detection in rats.
“There is an urgent need to strengthen cargo inspection, as existing inspection tools are expensive and time-consuming,” Schott explained.
“The APOPO rat is a cost-effective odor detection tool that can easily access tight spaces, such as cargo inside packed shipping containers, and can also be lifted high to block ventilation systems in closed containers.”
rat boot camp
The new research rats, Kirsty, Marty, Attenborough, Irwin, Betty, Teddy, Ivory, Ebony, Desmond, Thoreau, and Fosse, have undergone several rigorous training stages.
They first learned to “nose” a target’s scent for a few seconds to acquire a flavored pellet. Next, we discussed common scents used to hide wild animals in real-life human trafficking, such as electrical wires, coffee beans, and detergent.
The final step was retention training, where I re-experienced scents I had not been exposed to for 5 and 8 months respectively. Despite several months of no exposure, the rats showed perfect memory retention scores, suggesting that their cognitive retention performance is similar to that of dogs.
By the end of the training, eight of the rats were able to identify four commonly smuggled wild animals among 146 non-target substances.
Why now?
Statistics on IWT (defined as the illegal capture, killing, or harvesting of animals or plants) have become increasingly bleak in recent years. of wild animals of the world fund (WWF) estimates that it is currently the fourth largest illicit trade in the world, with a value of more than £15 billion a year.
They also estimate that around 55 African elephants are killed for their tusks every day, amounting to more than 20,000 a year. It also found that rhino poaching increased by 9,000 percent in South Africa between 2007 and 2014.
While this clearly has a negative impact on wildlife populations, a 2019 study found that world bank It also estimates that long-term global losses to ecosystems affected by IWT are approximately $1-2 trillion (£700-1.5 trillion) per year.
Evaluation of crime
Scientists involved in the new detection study have already identified the next steps for the HEROrat project. The idea is to develop methods that allow rats to operate within ports, which are likely to be hotspots for smuggled wildlife.
To this end, the rats are outfitted with custom-made vests (possibly inspired by Virgin Atlantic’s iconic red flight attendant uniforms). When they pull a small ball attached to the chest of their vest with their paws, it makes a beeping sound. In this way, the rat can alert the handler when it detects a target.
“The vest is a great example of hardware development that can be useful across a variety of settings and tasks, including shipping ports to detect smuggled wildlife,” the co-authors said. Dr. Kate Webb.
The National Institute for Artificial Intelligence and Data Science in Britain has initiated a consultation process that may result in the redundancy of 440 employees.
In a memo sent to staff this month, the Alan Turing Institute announced an update on its new strategy, which involves focusing on a smaller number of projects.
Addressed to “affected employees,” the letter mentioned that government-backed labs might have to reduce their workforce. Unofficial estimates suggest that the memo could have been sent to about 140 individuals.
The institute collaborates with universities, private companies, and government agencies on 111 active projects. An internal document states that they will need to scale back their involvement in some projects.
Last year, the institute introduced a new strategy called “Turing 2.0,” with a focus on health, environment, defense, and security. However, due to lower core funding, they are considering restructuring and potentially closing certain projects.
The institute is evaluating which projects align with their new strategy and could lead to staff reductions. They aim to minimize layoffs and will involve employee representatives in the decision-making process.
Dr. Jean Innes, the institute’s CEO, mentioned that they are entering a new ambitious phase to address societal challenges using technology.
Named after the renowned mathematician, the institute was initially focused on data science before including AI in its mission in 2017. Its objectives include conducting top-notch research to tackle global issues and fostering informed discussions about AI.
With upcoming government announcements on technology, the institute is gearing up for potential changes. This includes launching an “AI Action Plan” led by Technology Entrepreneur Matt Clifford, focusing on economic growth and public service enhancement.
Additionally, there are plans to establish a legally binding AI model testing agreement with tech companies, separate the UK AI Safety Institute from the Turing Institute, and introduce a consultation on the proposed AI bill.
Our planet’s new small satellite, 2024 PT5, arrived in Earth’s orbit on September 29, 2024.
2024 PT5 is scheduled to capture a temporary flyby from September 29th to November 25th in 2024. Image credit: University of Colorado.
2024 PT5 was discovered by the Asteroid Earth Impact Final Warning System in Sutherland, South Africa on August 7, 2024.
This near-Earth asteroid is about 10 meters (33 feet) in diameter and follows an orbit similar to that of 2022 NX1.
2024 PT5 will become a mini-Earth satellite on September 29 and return to heliocentric orbit 56.6 days later on November 25.
“Near-Earth objects like this offer a glimpse into the formation process of the solar system,” said astrophysicist Dr. Nico Cappellutti. University of Miami.
“Most asteroids in our solar system are rocky remnants left over from the formation of our solar system.”
2024 PT5 is part of Arjuna, an asteroid belt made up of space rocks that follow an orbit around the sun very similar to Earth’s orbit.
“So sometimes they can remain temporarily trapped in our gravitational field,” Dr. Cappellutti said.
“Bringing them this close is a fascinating opportunity.”
“The asteroid, the size of a school bus, is too faint and small to be seen with the naked eye or with amateur telescopes, but its two-month stay around Earth has reinforced our intense interest in space rocks. It helps maintain.”
Two years ago, in what was called the first test of the planetary defense system, NASA crashed a spacecraft into the giant space rock Dimorphos, which could change direction if the asteroid was on a collision course with Earth. proved something.
Private companies also want to send spacecraft to asteroids in hopes of mining the precious metals they contain.
“Asteroids are classified based on their orbits and their contents,” said Dr. Bertrand Dano, also from the University of Miami.
“Some are made entirely of stone, while others contain high concentrations of rare metals, such as platinum and gold for electronics, nickel and cobalt for catalysts and fuel cell technology, and, of course, iron.”
“Mining asteroids is not far off. There are currently millions of asteroids in our solar system, about 2 million of which are larger than 1 km.”
“The resources it contains are a new dream for El Dorado, and there are several companies currently betting on it.”
“Recent missions to rendezvous with, orbit and land on asteroids have proven that space mining may be only a matter of time.”
“However, proceeding with asteroid mining will require huge investments, from the mining equipment that needs to operate in a vacuum to the technology needed to transport the extracted minerals to Earth.”
“And then there’s the spacecraft itself. A dedicated ship that would travel to an asteroid for the purpose of extracting minerals from the asteroid would probably be a robotic ship.”
“A trip to Mars would take about eight months under the best conditions. The space and equipment needed to support life would be put to good use as storage for backup equipment and resources.”
“Because it takes a lot of energy to leave Earth’s gravity, mining missions are better launched from space or from low-gravity bodies such as the Moon, Mars, or Titan, one of Saturn’s natural moons. Sho.”
“Returning to Earth is relatively easy, but dangerous for the material. It would be a shame if all the prizes disappeared. Refining will take place in space, and purified products can be shipped regularly. As far as I know, no one is thinking that far.”
“Yet, asteroid mining could have a 100-fold or more return.”
“Mining platinum or gold from an asteroid and returning it could make you a trillionaire overnight, potentially upending entire economies, trade and markets.”
“Astrophysicist Neil deGrasse Tyson once said, ‘The first billionaire in history was the one who exploited the natural resources of asteroids.'”
Xibalbanus turmensisThe poisonous remipede, found in the caves of Antiarin on the Yucatan Peninsula, is the only crustacean for which a venom system has been described.
“Poisonous animals inject toxic compounds into other organisms primarily for self-defense or predation,” said Dr. Björn von Roymont, a researcher at Goethe University Frankfurt, and his colleagues.
“Many venoms are composed of proteins that have evolved to modulate various physiological functions in the target organism.”
“Studying these biological activities could lead to pharmacological or agrochemical applications.”
“The majority of thoroughly studied venoms and venomous proteins originate from iconic terrestrial groups, primarily snakes, spiders, scorpions, and insects,” the researchers said.
“Research attention to marine life has been limited, with only a few fish and invertebrates being better studied, such as sea anemones, jellyfish, cone snails, cephalopods, polychaetes, and more recently nemertes.”
“Venoms and their toxic proteins have evolved independently in different animal lineages, so the study of new lineages provides an opportunity to identify novel toxic compounds with interesting biological activities, on the one hand, and generally convergent proteins on the other hand. It provides an opportunity to improve our understanding of the evolution of functional traits.”
In their study, the researchers investigated the biological activity of peptides found in crustacean venom. Xibalbanus turmensis.
This underwater cave-dwelling crustacean belongs to the following classes: Remipediafirst described in the 1980s and currently consists of 28 extant species.
“Xibalbanus turmensis They live in cenotes, underwater caves in Mexico's Yucatan Peninsula,” the scientists said.
“Cave dwellers directly inject the venom produced by their venom glands into their prey.”
“This toxin contains a variety of components, including a new type of peptide named cibalbin after the crustacean producer.”
“Some of these sibalbins contain characteristic structural elements that are well known to other toxins, especially those produced by spiders. Some amino acids (cysteine) in the peptide are tied together like a knot. are connected to each other in such a way that they form a structure.
“This makes the peptide more resistant to enzymes, heat, and extreme pH values.”
“Such knots often act as neurotoxins, interacting with ion channels to paralyze prey. This effect has also been proposed for some cibalbins.”
This study shows that all sibalbin peptides tested by the team, particularly Xib1, Xib2, and Xib13, effectively inhibit potassium channels in mammalian systems.
“This inhibition is very important when developing drugs to treat a variety of neurological diseases, including epilepsy,” Dr. von Roymont said.
“Xib1 and Xib13 also exhibit the ability to inhibit voltage-gated sodium channels, such as those found in neurons and cardiomyocytes.”
“Furthermore, in higher mammalian sensory neurons, the two peptides can activate two proteins involved in signal transduction: the kinases PKA-II and ERK1/2.”
“The latter suggests that they are involved in pain sensitization, opening the door to new approaches in pain treatment.”

Gravity is one of the four fundamental forces that bind matter in the universe. The other three forces (electromagnetic, weak nuclear, and strong nuclear) are explained through the exchange of force-carrying elementary particles, leading theorists to believe there is a similar quantum explanation for gravity.
The force carriers for the electromagnetic force are photons, while the weak nuclear force has W-, W+, and Z0 bosons as force carriers, and the strong nuclear force has eight types of gluons. On the other hand, the hypothetical carrier of gravitational force is known as the graviton.
The properties of the graviton are deducible in quantum theory. The amount of energy required to summon a force-carrying particle from the vacuum determines how quickly it must be recovered. Since gravity has an infinite range and does not require energy to create a graviton, the mass of the graviton must be zero.
Additionally, gravitons are expected to have a spin of 2, as only spin 2 particles interact with all matter, which is characteristic of universal gravity. This is in contrast to quarks and leptons, which have a spin of 1/2, and the non-gravitational force carriers, which have a spin of 1.
While gravity may not be fully explained by the exchange of gravitons, most physicists believe it can be quantized. String theory offers a potential framework where fundamental particles are envisioned as vibrations of mass-energy strings, with each vibrating string having the properties of a graviton.
However, string theory faces challenges due to its complexity and inability to make testable predictions. Detecting gravitons is difficult due to the extremely weak nature of gravity and the rare interactions gravitons have with matter.
Despite the challenges in detecting gravitons, recent advancements in experimental exploration, such as the discovery of spin-2 particle properties in a liquid analogue system, provide hope for a better understanding of gravitons and the eventual unification of fundamental forces into a single theory.

Water on Mars may be lurking beneath or even above the planet’s surface.
NASA/JPL/USGS
Mars isn’t as dry as it seems. Billions of years ago, oceans and rivers of liquid water rippled across its surface, but now it appears that all of that liquid has disappeared, leaving behind a dusty barren landscape. But as we explore Mars with probes, landers, rovers, and even distant telescopic images, more and more traces of water are popping up.
Each hint fascinates researchers about how important water is to life and how it could aid future exploration. Water has now been found in various forms all over Mars. Here are five places where water has been found.
1. Buried underground
The InSight lander, visualized here, recently discovered new potential water reservoirs on Mars.
NASA/JPL-California Institute of Technology
Just beneath Mars’ dry surface lies an icy wonderland. These deposits are insulated by an overlying layer of dust, but erosion or meteorite impacts could expose them to the watchful eye of Mars orbiters. A single icy deposit recently identified using data from the Mars Express spacecraft appears to contain enough water to cover the entire Martian surface with an ocean 1.5 to 2.7 meters deep.
It’s not just ice buried under the orange sand. There’s a controversial theory that there’s a huge lake beneath Earth’s Antarctic pole. It could just be wet silt or volcanic rock. But… New Research Using data from the InSight lander, researchers have uncovered the possibility of another reservoir of water near the Martian equator. InSight found this water, buried 11.5 to 20 kilometers underground, by sensing Martian earthquakes and measuring the speed at which seismic waves travel. The results revealed that the rocks through which the earthquakes travel appear to be saturated with water.
2. Frost the pole

Reaching buried water on Mars will be difficult. For future explorers, the more promising reservoirs are probably exposed on the surface. Mars has ice caps at both poles, just like Earth’s, and we’ve known about them for decades. Many of Mars’ craters also contain small ice sheets inside them, the only places on the Martian surface cold enough to hold ice.
However, at higher latitudes on Mars, the air is cooler and more moist, and temporary frosts can occur. On frigid Martian mornings, volcano peaks are also covered in frost, likely caused by water vapor in the atmosphere freezing.
Using new data about the Martian crust collected by NASA’s InSight spacecraft, geophysicists from the University of California, San Diego and the University of California, Berkeley estimate that groundwater could cover the entire planet to a depth of one to two kilometers. Groundwater exists in tiny cracks and pores in rocks in the mid-crust, 11.5 to 20 kilometers below the surface.

“Liquid water existed at least occasionally in Martian rivers, lakes, oceans, and aquifers during the Noachian and Hesperian periods more than 3 billion years ago,” said Dr Vashan Wright of the Scripps Institution of Oceanography at the University of California, San Diego, and his colleagues.
“During this time, Mars lost most of its atmosphere and therefore the ability to support liquid water on its surface for any sustained period of time.”
“Ancient surface water may have been incorporated into minerals, buried as ice, trapped as liquid in deep aquifers, or lost to space.”
For the study, Dr Wright and his colleagues used data collected by InSight during its four-year mission, which ends in 2022.
The lander collected information from the surface directly beneath it about variables such as the speed of Mars’ seismic waves, which allowed scientists to infer what materials exist beneath the surface.
The data was fed into a model based on mathematical theories of rock physics.
Based on this data, the researchers determined that the presence of liquid water in the Earth’s crust was the most plausible explanation.
“If we prove that there is a large reservoir of liquid water, it could give us insight into what the climate was or could be like at that time,” said Professor Michael Manga of the University of California, Berkeley.
“And water is essential for life as we know it. I don’t see why underground reservoirs wouldn’t be habitable environments. On Earth they certainly are. There is life in deep mines, there is life at the bottom of the ocean.”
“We still don’t have evidence of life on Mars, but we’ve identified places that could, at least in principle, support life.”
“A wealth of evidence, including rivers, deltas, lake deposits, and hydrologically altered rocks, supports the hypothesis that water once flowed on the planet’s surface.”
“But that wet period ended more than 3 billion years ago, when Mars lost its atmosphere.”
“Planetary scientists on Earth have sent many probes and landers to Mars to learn what happened to the Martian water (water frozen in the Martian polar ice caps does not explain the whole story), when this happened, and whether life exists or ever existed on Mars,” the authors said.
“The new findings indicate that much of the water has seeped into the crust rather than escaping into space.”
“The new paper analyzes the deeper crust and concludes that the available data are best explained by a water-saturated mid-crust beneath the InSight location.”
“Assuming the crust is similar across the planet, this mid-crustal zone should contain more water than would have filled the hypothetical ancient Martian ocean.”

Mars A recent study indicates that the Earth may be hiding a global ocean beneath its surface, with cracks in rocks potentially holding enough water to form it.
Scientists believe that the water lies about seven to 12 miles (11.5 to 20 kilometers) deep in Mars’ crust, possibly originating from the planet’s ancient surface water sources such as rivers, lakes, and oceans billions of years ago, according to Vashan Wright, the lead scientist at the Scripps Institution of Oceanography at the University of California, San Diego.
Despite the presence of water inside Mars, Wright noted that it does not necessarily mean that life exists there.
“However, our findings suggest the possibility of habitable environments,” he mentioned in an email.
The research team combined computer simulations with InSight data, including earthquake speeds, to suggest that groundwater is the most likely explanation. These results were published in the Proceedings of the National Academy of Sciences on Monday.
Wright remarked that if InSight’s observations near the equator of Mars at Elysium Planitia are representative of the entire planet, there could be enough groundwater to fill a terrestrial ocean approximately a mile (1 to 2 kilometers) deep.
Tools like drills will be required to verify the presence of water and search for signs of microbial life.
Despite the InSight lander no longer being in operation, scientists are still analyzing the data collected between 2018 and 2022 to gain more insights into Mars’ interior.
Over 3 billion years ago, Mars was mostly covered in water, but due to the thinning of its atmosphere, it lost its surface water, becoming the dry and dusty world we see today. It is believed by scientists that the ancient water either escaped into space or remains hidden underground.
pictureRon Musk has long been interested in right-wing politics and has enjoyed portraying himself as a contrarian showman. However, his recent political affiliations have raised doubts about Tesla, the electric-car giant he founded. How much further can he push before customers start abandoning his product?
A German pharmacy chain, Rothmann, was among the first to speak out this week. The family business announced that it would not expand its fleet of 34 Tesla cars after Musk publicly supported Donald Trump for US president.
Rothmann’s spokesperson, Raul Rothman, wrote, “Mr. Trump has consistently denied climate change, which contradicts Tesla’s mission to protect the environment by producing electric vehicles.”
Musk’s support for Trump was followed by controversial posts about far-right riots in the UK. He made remarks like “Civil war is inevitable,” which sparked criticism from politicians across the spectrum. Musk engaged with far-right figures, raising concerns among some consumers.
Some Tesla owners are now reevaluating their choice of vehicle due to Musk’s recent behavior.
Given the divisive nature of Mr. Musk’s comments and his apparent enjoyment of creating discord, we have decided to discontinue our relationship with Tesla.”
Tesla has been reached out to for comment.
In online forums, Tesla owners debate the impact of Musk’s politics on the brand. Some have created bumper stickers like “I bought this before I knew Elon was crazy.”
David Bach, a strategy and political economy professor at IMD, noted that Musk’s recent behavior sets him apart from other CEOs. Musk’s actions have garnered mixed reactions, especially in the UK.
Tesla’s sales in the UK account for a small portion of its global business. Musk’s involvement in US politics, particularly with Trump, could have significant repercussions for Tesla.
Despite Musk’s polarizing comments, some consumers still support Tesla. However, there are concerns about the potential impact on business.
Musk’s actions have already affected X and could impact SpaceX as well. Some industry insiders believe that Musk’s current path could eventually lead to a decline in Tesla’s sales.
Black holes have the ability to die, but this process happens very slowly and in a rather normal manner.
Despite appearing empty, space is not entirely devoid of mass or energy. Within this space, there exist “quantum fields” that give definition to mass and energy. These fields do not necessarily have zero energy, allowing for the creation of pairs of “virtual particles” (typically particle and antiparticle pairs) that quickly eliminate each other.
Another common explanation is that near a black hole, one of these particles may vanish inside the black hole while the other escapes as “Hawking radiation.”
In order to maintain the total energy of a black hole, incoming particles must possess “negative energy” (hence “negative mass”) while escaping particles must have positive energy.
Hawking radiation is a result of gravity’s impact on space-time. Quantum fields within empty space adhere to the Heisenberg uncertainty principle, limiting our understanding of the energy of a quantum field or the duration for which we can attribute a specific energy to it.
Since gravitational fields influence the curvature of space-time and the flow of time in a given area, regions of space-time with varying gravitational curvatures struggle to agree on the energy of the quantum field.
The variance in vacuum energy within different points of a black hole’s gravitational field creates what are known as “virtual particles.”
As positive energy escapes from a black hole, the mass and energy of the black hole gradually diminish, causing a black hole that is not actively attracting new material to gradually shrink and ultimately vanish.
However, this process occurs over massive time scales. For instance, a black hole with the mass of the sun would take 1064 years to evaporate, far surpassing the age of the universe at 10 years old.
This article endeavors to answer Catrin Phelps of Winchester’s question, “Can black holes ever die?”

Terraforming Mars would make it more similar to Earth, creating an environment capable of supporting life as we know it.

Releasing iron rods the size of glitter particles into the Martian atmosphere could raise the planet's temperature enough to melt water and support microbial life.
Making the Red Planet's surface habitable for Earth-like life – a process known as “terraforming” – will be a complex one, but a key part of it will be raising the surface temperature above the current median freezing point of -65°C (-85°F).
Some have suggested placing mirrors on the Martian surface or pumping methane into the atmosphere, but these ideas are difficult to implement because the necessary raw materials would need to be shipped from Earth.
now, Edwin Kite Researchers at the University of Chicago in Illinois found that a relatively tiny dust cloud (about 9 micrometers long and 160 nanometers wide) made from iron or aluminum rods mined from Martian rocks could warm Mars by about 30 degrees Celsius over the course of a few months to more than a decade, depending on how quickly the particles are released.
These rods, each about 9 micrometers long and 160 nanometers wide, are carried by winds from the surface into Mars' upper atmosphere, where they will remain for about 10 years, trapping heat from the surface and transmitting sunlight.
Kite and his colleagues modeled how the rods respond to light and fed that information into climate simulations, which showed that the increased temperature and pressure would be enough to support liquid water and possibly oxygen-producing bacteria in parts of Mars.
They also found that to achieve this warming, it would be enough to release the fuel rods at a rate fast enough to power about 30 garden sprinklers — a total of 700,000 cubic meters of metal per year, or about 1% of Earth's metal production.
“When we did the math, we found that the amount of man-made dust we needed would be surprisingly small — much less than we would need to create the same amount of warming with man-made greenhouse gases,” Kyte says.
While mining the Martian surface would still be difficult, Kite says this would be 5,000 times more efficient than any warming method proposed so far.
One of the big uncertainties in the simulations is how the tiny bars interact with water in the Martian atmosphere, which could have unexpected effects such as causing the water to collect around the dust and rain down back to the surface, reducing global warming.
It's an intriguing idea that might work if the particles remain in the atmosphere long enough, he said. Manoj Joshi researcher at the University of East Anglia in the U.K. But even if the amount of metal needed is small, he says it would still be an enormous amount of work to produce.
Joshi said there are also ethical questions about whether it's OK to alter the atmosphere of another planet: “Mars is so unexplored and we don't know much about it. Is it OK to alter a planet in this way?”
It’s been a tough week for the Grand St. Seven, a group of technology stocks that have played a leading role in the U.S. stock market, buoyed by investor excitement about breakthroughs in artificial intelligence.
Last year, Microsoft, Amazon, Apple, chipmaker Nvidia, Google parent Alphabet, Facebook owner Meta and Elon Musk’s Tesla accounted for half of the S&P 500’s gains. But doubts about returns on AI investments, mixed quarterly earnings, investor attention shifting elsewhere and weak U.S. economic data have hurt the group over the past month.
Things came to a head this week when the shares of the seven companies entered a correction, with their combined share prices now down more than 10% from their peak on July 10.
Here we answer some questions about Seven and the AI boom.
Why did AI stocks fall?
First, there are concerns that the huge investments being made by Microsoft, Google and others in AI will pay off. These have been growing in recent months. Goldman Sachs analysts The memo was published In June, the Wall Street bank released a report titled “Gen AI: Too Much Spending, Too Little Reward?” which asked whether $1 trillion in investment in AI over the next few years “will ever pay off,” while an analysis by Sequoia Capital, an early investor in ChatGPT developer OpenAI, estimated that tech companies would need $600 billion in rewards to recoup their AI investments.
Gino said “The Magnificent Seven” is also hit by these concerns.
“There are clearly concerns about the return on the AI investments that they’re making,” he said, adding that big tech companies have “done a good job explaining” their AI strategies, at least in their most recent financial results.
Another factor at play is investor hope that the Federal Reserve, the U.S. central bank, may cut interest rates as soon as next month. The prospect of lower borrowing costs has boosted investors’ support for companies that could benefit, such as small businesses, banks and real estate companies. This is an example of “sector rotation,” in which investors move money between different parts of the stock market.
Concerns about the Big 7 are affecting the S&P 500, given that a small number of tech stocks make up much of the index’s value.
“Given the growing concentration of this group within U.S. stocks, this will have broader implications,” said Henry Allen, macro strategist at Deutsche Bank AG.Concerns about a weakening U.S. economy also hit global stock markets on Friday.
What happened to tech stocks this week?
As of Friday morning, the seven stocks were down 11.8% from last month’s record highs, but had been dipping in and out of correction territory — a drop of 10% or more from a recent high — in recent weeks amid growing doubts.
Quarterly earnings this week were mixed. Microsoft’s cloud-computing division, which plays a key role in helping companies train and run AI models, reported weaker-than-expected growth. Amazon, the other cloud-computing giant, also disappointed, as growth in its cloud business was offset by increased spending on AI-related infrastructure like data centers and chips.
But shares of Meta, the owner of advertising-dependent Facebook and Instagram, rose on Thursday as the company’s strong revenue growth offset promises of heavy investment in AI. Apple’s sales also beat expectations on Thursday.
“Expectations for the so-called ‘great seven’ group have perhaps become too high,” Dan Coatsworth, an analyst at investment platform AJ Bell, said in a note this week. “These companies’ success puts them out of reach in the eyes of investors, and any shortfall in greatness leaves them open to harsh criticism.”
A general perception that tech stocks may be overvalued is also playing a role: “Valuations have reached 20-year highs and they needed to come down and take a pause to digest some of the gains of the past 18 months,” says Angelo Gino, a technology analyst at CFRA Research.
The Financial Times reported on Friday that hedge fund Elliott Management said in a note to investors that AI is “overvalued” and that Nvidia, which has been a big beneficiary of the AI boom, is in a “bubble.”
Can we expect to see further advances in AI over the next 12 months?
Further breakthroughs are almost certain, which may reassure investors. The biggest players in the field have a clear roadmap, with the next generation of frontier models already underway to train, and new records are being set almost every month. Last week, Alphabet Inc.’s Google DeepMind announced that its system had set a new record at the International Mathematical Olympiad, a high school-level math competition. The announcement has observers wondering whether the company will be able to tackle long-unsolved problems in the near future.
The question for labs is whether these breakthroughs will generate enough revenue to cover the rapidly growing costs of achieving them: The cost of training cutting-edge AI has increased tenfold every year since the AI boom really began, raising questions about how even well-funded companies such as OpenAI, the Microsoft-backed startup behind ChatGPT, will cover those costs in the long run.
Is generative AI already benefiting the companies that use it?
In many companies, the most successful uses of generative AI (the term for AI tools that can create plausible text, voice, and images from simple prompts) have come from the bottom up: people who have effectively used tools like Microsoft’s Copilot or Anthropic’s Claude to figure out how to work more efficiently, or even eliminate time-consuming tasks from their day entirely. But at the enterprise level, clear success stories are few and far between. Whereas Nvidia got rich selling shovels in the gold rush, the best story from an AI user is Klarna, the buy now, pay later company, which announced in February that its OpenAI-powered assistant can: Resolved two-thirds of customer service requests In the first month.
Dario Maisto, a senior analyst at Forrester, said a lack of economically beneficial uses for generative AI is hindering investment.
“The challenge remains to translate this technology into real, tangible economic benefits,” he said.
Google states that nearly 66% of jobs in the UK could be “augmented” by AI, with only a small percentage of jobs at risk of complete elimination. The company emphasizes the importance of supporting workers to utilize AI technology to improve efficiency rather than fearing job loss.
Debbie Weinstein, managing director of Google UK, highlights the low adoption rate of AI tools in workplaces and emphasizes the need for people to feel confident and capable in using these technologies to unlock their full potential.
Research commissioned by Google from think tank Public First reveals that 61% of UK jobs will be significantly impacted by AI, with only 31% remaining unaffected by the technology. Certain industries like social care, transportation, and accommodation and food services, which involve complex physical labor, are less likely to be automated.
Public First estimates that only a few jobs will become obsolete due to AI, with the majority of jobs expected to be enhanced instead. Google has partnered with various organizations to introduce AI technologies in a way that enhances worker capabilities without replacing them.
The government is also supporting the adoption of AI across the economy to drive growth and provide new opportunities for workers. Minister for AI, Feriel Clarke MP, emphasizes the importance of AI skills training to help workers thrive in the changing job market.
Public First predicts that full adoption of AI over the next six years could bring significant economic benefits to the UK, with an annual growth rate of 2.6% driven by technology alone. Google claims that using generative AI could save the average UK worker 100 hours a year, marking the biggest improvement in productivity since the introduction of Google Search.
Despite some controversies surrounding AI tools like Gemini AI, Google continues to invest in AI products and features to enhance user experiences. The company aims to revamp Google search with AI Briefs, although this has faced criticism for potentially reducing traffic to publisher sites.
A newly identified brain pathway in mice may explain why placebos, or interventions that should have no therapeutic effect, can relieve pain, and the development of drugs that target this pathway could lead to safer alternatives to painkillers such as opioids.
If someone unknowingly takes a sugar pill instead of a painkiller, they still feel better. The placebo effect is a well-known phenomenon in which people's expectations reduce symptoms even in the absence of an effective treatment. “Our brain can solve the pain problem on its own, based on the expectation that a drug or treatment might work,” says Dr. Gregory Scherer At the University of North Carolina at Chapel Hill.
To understand how the brain does this, Scherer and his colleagues recreated the placebo effect in 10 mice using a cage with two chambers: one with a blazingly hot floor and the other with no floor. After three days, the mice learned to associate the second chamber with pain relief.
The researchers then injected molecules into the animals' brains that caused active neurons to light up when viewed under a microscope, and then returned the animals to their cages, but this time they heated both floors.
Although the two chambers were now equally hot, the mice still preferred the second chamber and showed less symptoms of pain, such as licking their paws, while they were there. They also showed more neuronal activity in the cingulate cortex, a brain region involved in processing pain, compared with nine mice that had not been conditioned to associate the second chamber with pain relief.
Further experiments revealed pathways connecting these pain-processing neurons to cells in the pontine nuclei and cerebellum, two brain regions not previously known to play a role in pain relief.
To confirm that this circuit relieved pain, the researchers used a technique called optogenetics, which switches cells on and off with light. This allowed them to activate the newly discovered neural pathway in another group of mice that were placed on a hot floor. On average, these mice took three times longer to lick their paws than mice that didn't have the circuit activated, indicating that they felt less pain.
If this neural pathway explains the placebo effect, “it could open up new strategies for drug development,” he said. Luana Colocca “If we had a drug that could activate the placebo effect, it would be an excellent strategy for pain management,” said University of Maryland researcher David L. Schneider, who was not involved in the study.
“An obvious caveat is that the placebo experience in humans is clearly much more complex. [than in animals]”The pain pathways are very similar to ours,” Scherer said, but because rodents and humans have very similar pain pathways, he believes these findings also apply to humans.
No one doubts that Albert Einstein had a brilliant mind, but the Nobel Prize winner famous for his theories of special and general relativity wasn’t blessed with a big brain. “Jeremy DeSilva at Dartmouth College in New Hampshire.”
This seems surprising. Big brains are a defining feature of human anatomy, something we are proud of. Other species may be faster or stronger, but we thrive using the ingenuity that comes from our big brains. At least, that’s what we tell ourselves. Einstein’s brain suggests that the story is not so simple. And recent fossil discoveries bear this out. In the past two decades, we’ve learned that small-brained hominin species persisted on Earth long after species with larger brains emerged. Moreover, there is growing evidence that they were behaviorally sophisticated. For example, some of them made complex stone tools that could only have been made by humans with language.
These findings turn questions about the evolution of the human brain upside down: “Why would large brains be selected for when humans with small brains can survive in nature?” says DeSilva. Nervous tissue consumes a lot of energy, so large brains must have undoubtedly provided an advantage to the few species that evolved them. But what was the benefit?
The answer to this mystery is beginning to emerge. It appears that brain expansion began as an evolutionary accident that then led to changes that accelerated brain growth. Amazingly, the changes that drove this expansion also explain the recent 10 percent shrinkage of the human brain. What’s more, this suggests that our brains could shrink even further, potentially causing our demise.
Picture this: a hacker sitting at their laptop, frantically typing code as it flashes across the screen. Suddenly, they successfully hack into a satellite. Sounds like a scene from a James Bond movie, doesn’t it? But in reality, it poses a real threat.
Contrary to the dramatic portrayal in movies, hacking a satellite is much more complex than simply having a laptop and a strong internet connection. The issue of cybersecurity in space is becoming increasingly concerning as the number of operational satellites continues to grow.
By the end of 2022, there were 6,718 operational satellites orbiting the Earth, representing a significant increase from the previous year. With 10,206 objects in space, predominantly satellites, the space environment is rapidly expanding.
Satellites play crucial roles in GPS navigation, military surveillance, and banking systems, making them attractive targets for potential hackers. But despite their vulnerability, instances of successful hacks on satellites are rare. So, how can a satellite be hacked, and what are the potential consequences?
How can a satellite be hacked?
While space may seem like a distant realm filled with satellites in remote galaxies, most satellites actually orbit in low earth orbit (LEO), between 99 and 1,243 miles above Earth. Physically accessing a satellite remains a challenge, but there are various methods hackers can employ to compromise satellites without venturing into space.
According to Anuradha Dhamal Dey, a SpaceX space ecosystem manager at Satellite Applications Catapult, potential satellite hacking methods include physical attacks, cyber attacks, and the use of kinetic anti-satellite (ASAT) technology. These methods have raised concerns about the security of space-based systems.
ASAT refers to any means of destroying a satellite, with kinetic ASAT involving physical strikes on satellites, such as through ballistic missiles or drones. While kinetic ASAT attacks are unprecedented outside of testing scenarios, non-kinetic attacks using malware or viruses pose a theoretical threat to satellite security.
Despite these risks, no actual satellite hacks have occurred yet. In 2023, the US Air Force organized Hack the Sat event to test satellite vulnerabilities, with three teams successfully breaching a satellite’s security.
What will happen?
While satellite hacking remains theoretical, the potential consequences of a successful attack are significant. Space plays a vital role in various industries, from national security and defense to everyday services like food delivery and entertainment.
A powerful DNA-editing mechanism discovered in bacteria has the potential to enable much larger genome modifications than are currently possible with CRISPR-based techniques, but it is not yet clear whether it would work in human cells.
Patrick Shue Researchers at the Ark Institute in California call their new genome editing system the “bridge editing” system because it physically links, or bridges, two strands of DNA. “Using this system, we can modify large parts of the genome,” says Su. Su's team has figured out how bacterial “parasitic” DNA sequences naturally replicate using this system and how it can be applied to genome editing.
“We're excited about the possibility of making much broader genome modifications that go far beyond what we can do today with CRISPR,” he says, “and we see this as an important step toward a broader vision for genome design.”
CRISPR gene editing has revolutionized biology since it was introduced in 2012. It is used for a variety of purposes, and the first CRISPR-based therapeutic was approved last year. However, the basic form of CRISPR, which uses the Cas9 protein, is gene disruption rather than gene editing.
A standard CRISPR Cas9 protein has two parts: one part binds to a guide RNA molecule and looks for DNA that matches a specific section of the guide RNA. Custom guide RNAs are easy to create, so CRISPR Cas9 can be “programmed” to look for any part of the genome.
The second part of CRISPR Cas9 is a cutter that cuts the DNA when Cas9 binds to the target site. Once the cell has repaired the damage, Cas9 cuts it again. This action continues until an error is made during repair, resulting in the intended mutation of the target site.
While being able to mutate specific sites is useful, biologists want to make more precise changes, so they are modifying CRISPR proteins to edit DNA directly rather than relying on cellular repair mechanisms. For example, base editors can change one DNA letter to another without cutting the DNA, while prime editors can convert an extra section of guide RNA into DNA and add it to the target site.
These improved versions of CRISPR have the potential to treat a wide range of diseases, with several clinical trials already underway, but to address some diseases, more sophisticated genome modifications are needed. Many teams around the world are working on ways to achieve this. Some have realized that the mechanism by which genetic parasites cut and paste from one part of the genome to another, called IS110 elements, has potential because, like CRISPR, it is RNA-guided, but Hsu's team is the first to fully understand how it works.
The bridge-editing system consists of a so-called recombinase protein that binds to a guide RNA, such as the CRISPR Cas9 protein. What's unique about this system is that the guide RNA specifies two DNA sequences to seek out, not just one, Hsu's team found.
One sequence specifies the target site in the genome to modify, similar to CRISPR, and the other specifies the DNA to change. Using this system, DNA sequences of virtually any length can be added, deleted, or inverted.
There are already ways to do this, but they typically require multiple steps and leave behind a piece of extra DNA called a scar. “Bridge editing leaves virtually no scar,” Hsu says. “It offers an unprecedented level of control in engineering the genome.”
This means that it could be used for more than just replacing faulty genes, he says: It could also be useful for completely remaking the genomes of plants and animals. “What we want to do is go from inserting individual genes to doing chromosome-scale genome engineering,” Su says.
“The findings reported are certainly exciting and the underlying biology is truly surprising.” Steven Tang Bridge editing is being done at Columbia University in New York, but so far it has only been demonstrated to work in bacterial cells or in test tubes. Tang says it remains to be seen whether and to what extent bridge editing will work in complex cells like humans. But even if bridge editing doesn't work in initial tests in human cells, it may be possible to modify the system to work over time.
Ocean worlds are planetary bodies with liquid oceans, often beneath an icy shell or within rocky interiors. In our solar system, several moons of Jupiter and Saturn are ocean worlds. Some ocean worlds are thought to have hydrothermal circulation, where water, rocks, and heat combine to pump and expel fluids to the ocean floor. Hydrothermal circulation influences the chemical composition of the water and rocks of ocean worlds and may help life develop deep beneath the icy surface. In a new study, planetary researchers used computer simulations of hydrothermal circulation based on well-understood systems on Earth to measure the effects of low gravity at values appropriate for ocean worlds smaller than our home planet. Simulations of ocean worlds with (lower) gravity result in fluid circulation that is roughly similar to that which occurs above and below the ocean floor on Earth, but with some key differences. Low gravity reduces buoyancy, so fluids do not become lighter as they heat up, which reduces their flow rate. This increases the temperature of the circulating fluids, which could lead to more extensive chemical reactions, possibly including those necessary to support life.

Rock-heat-fluid systems were discovered on the Earth’s ocean floor in the 1970s, where scientists observed releases of fluids carrying heat, particles, and chemicals.
Many of the vents were surrounded by a novel ecosystem, including specialized bacterial mats, red and white tube worms and heat-sensing shrimp.
For the new study, Professor Andrew Fisher from the University of California, Santa Cruz, and his colleagues used a complex computer model based on the hydrothermal cycle that occurs on Earth.
After varying variables such as gravity, heat, rock properties and depth of fluid circulation, the researchers found that hydrothermal vents could persist under a wide range of conditions.
If these flows occurred on an ocean world like Jupiter’s moon Europa, they could increase the chances of life surviving there as well.
“This study suggests that extraterrestrial ocean worlds may have supported low-temperature (but not hot enough for life) hydrothermal systems on timescales similar to those it took for life to become established on Earth,” Prof Fischer said.
The ocean circulation system on which the researchers based their computer model was discovered on the 3.5-million-year-old seafloor of the northwest Pacific Ocean, east of the Juan de Fuca Ridge.
There, cold undersea water flows through an extinct volcano (seamount), travels about 30 miles (48.3 km) underground, and then flows out into the ocean through another seamount.
“As water flows, it picks up heat, it’s warmer than when it entered, and its chemistry changes dramatically,” says Kristin Dickerson, a doctoral student at the University of California, Santa Cruz.
“The flow from seamount to seamount is driven by buoyancy – as water warms it becomes less dense and as it cools it becomes more dense,” Prof Fischer added.
“The difference in density creates a difference in fluid pressure within the rock, and the system is sustained by the flow itself. So as long as there is enough heat supplied and the rock properties allow for sufficient fluid circulation, the system will keep running. We call this a hydrothermal siphon.”
“Hot vent systems are primarily driven by sub-sea volcanism, while the Earth’s ocean floor experiences large amounts of fluid flowing in and out at much cooler conditions, driven primarily by Earth’s background cooling.”
“The flow of water through low-temperature vents is equivalent to all the rivers and streams on Earth in terms of the volume of water released, and accounts for about a quarter of the Earth’s heat loss.”
“About every 500,000 years, the entire volume of ocean water is pumped up and out of the ocean floor.”
Many previous studies of the hydrothermal circulation on Europa and Enceladus have considered hotter fluids.
“Cartoons and other illustrations often depict undersea systems that are similar to Earth’s black smokers, where cooler currents could occur just as much or even more than they do on Earth,” said Dr Donna Blackman from the University of California, Santa Cruz.
The results show that in very low gravity, such as on the ocean floor of Enceladus, the circulation can continue at low to moderate temperatures for millions or billions of years.
This could help explain why small ocean planets can have long-lived fluid circulation systems beneath their seafloors despite limited heating: the inefficiency of heat extraction could extend their lifetimes considerably, potentially for the entire lifetime of the solar system.
Scientists acknowledge that it is uncertain when active hydrothermal systems will be directly observed on the ocean planet’s seafloor.
The distance from Earth and physical characteristics pose significant technical challenges for spacecraft missions.
“It is therefore essential to make the most of the available data, much of which is remotely collected, and to leverage the understanding gained from decades of detailed study of the analog Earth system,” the authors concluded.

The Moon, Earth’s steadfast companion that remains in orbit, has been a popular subject of discussion since the early days of space exploration. Missions have been planned, rovers have explored its surface, and even a flag has been planted there.
But why all the interest? The Moon is over 400,000 km away from Earth, a considerable distance to travel, and it poses many challenges as a potential habitat for humans, such as exposure to solar radiation.
However, the Moon offers other advantages. Being largely untouched, it presents opportunities for planetary research, scientific experiments, and notably, mining for valuable resources.
There is a growing interest in lunar exploration, raising the important question of lunar ownership. Philosopher and author AC Grayling addresses this topic in his new book, “Who owns the moon?”
SF: Why are we interested in going to the moon, and will it ever happen?
ACG: The Moon holds vast resources, making it a lucrative target for mining operations. Coupled with the rapid pace of technological advancements, the obstacles to lunar exploration are likely to be overcome. Significant investments are being made in this endeavor, indicating the potential benefits that could be derived.
While some argue that lunar exploration is not feasible, the lure of valuable resources like Helium-3 for clean nuclear fusion makes the Moon an attractive destination for mining activities.
SF: So who actually owns the moon?
The 1967 Outer Space Treaty, agreed upon by the United Nations, asserts that the Moon cannot be militarized or claimed for sovereignty or ownership. It is considered a shared resource belonging to all of humanity.
With various nations eyeing lunar exploration and exploitation, concerns about potential conflicts arise, highlighting the need for clearer regulations and agreements.
What are the next steps? Will the law be strengthened?
Efforts are being made to establish binding regulations, but the presence of multiple space agencies and rivalries between nations complicate the process. Initiatives like the Artemis Accords aim to set guidelines for responsible behavior in space.
However, the prospect of a new space race between major powers like the US, China, and Russia raises concerns about the potential for conflict and competition in space.
Can history give us any indication of what might happen?
The Antarctic Treaty serves as a model for international cooperation in preserving shared resources. However, challenges to extend the treaty’s scope and conflicting claims in Antarctica hint at the complexities of managing common territories.
Similar issues could arise in lunar exploration, especially with the potential for valuable mineral resources like Helium-3. The absence of clear regulations and the lack of a universal agreement on space governance present significant hurdles.
Is there an argument to leave the moon alone?
Given the Moon’s vast and barren nature, concerns about environmental impacts are minimal compared to Earth. Utilizing lunar resources for space exploration and sustainable practices could be more beneficial in the long run.
What’s the next step after the moon?
The Moon’s potential as a refueling station for Mars missions opens up new possibilities for further space exploration. As colonies on celestial bodies evolve, questions of independence and governance will arise, shaping the future of human presence in space.
In conclusion, the direction of space activities will determine whether they align with values upheld on Earth or devolve into profit-driven ventures. Clear regulations and international cooperation are essential to ensure a sustainable and equitable future in space.
