Discovering Aurora on Neptune for the First Time with NASA’s Webb Telescope

The Northern and Southern Lights Vermillion, Amethyst, and Jade Ribbons are some of the most distinctive features of the Earth. However, our planet has no monopoly of the Aurora. Scientists spy on them throughout the solar system, weaving the Martian sky into Saturn, Jupiter and even some of Jupiter’s fiery softening.

The light shines in the sky Uranus too. However, the aurora around Neptune, the farthest planet of our Sun, has long escaped astronomers.

That was changed by the powerful infrared equipment installed in the James Webb Space Telescope. In a study published in the journal on Wednesday Natural Astronomy scientists reveal unique auroras spilling on either side of Neptune’s equator. This contrasts with the sparkling Gossamers, arcing at Poles in other worlds.

Astronomers are excited that the Aurora Hunting Quest has been completed over decades. “Everyone is very excited to prove it’s there, as we thought,” he said. Rosie Johnson an astrophysics researcher at Aberystwyth University in Wales who was not involved in new research.

The discovery allows scientists to study previously out-of-reach aspects of Neptune. “They use the aurora to understand the shape of the magnetic field on planets looking at the invisible,” he said. Karl Schmidt Boston University planetary astronomers were not involved in new research.

Each world produces aurora differently, but it is basically the same. Energy particles (often from the sun, but sometimes from the eruption of a lunar volcano) hit the atmosphere and bounce back the gas. The collision of the particles causes a temporary flash of light. And if there is a magnetic field in the world, it will guide the position…

Luckily, the Webb Telescope, released in 2021, came to rescue.

Heidi Hammel Another astronomer of the University Association for Astronomical Studies and the author of the research, has been studying Neptune since the 1980s. She said that if Webb “is powerful enough to see the early galaxies of the universe, it would be strong enough to see something like Neptune’s Aurorae.” “And by Golly, that was the case.”

Using the telescope’s near-infrared spectrometer, astronomers captured Neptune’s infrared aurora in June 2023. This is because Neptune has an unstable magnetic field tilted to 47 degrees from the planet’s spin axis.

New Webb observations also reveal why Neptune’s Auroras has never been visible until now. Almost 40 years ago, Voyager 2 recorded a temperature of about 900 degrees Fahrenheit in the Neptune’s upper atmosphere. However, the Webb telescope shows that the temperature has dropped nearly 200 degrees. This low temperature means that the aurora is a dimmer.

In fact, Neptune’s Aurora said, “It’s less than 1% of the expected brightness and explains why I’ve never seen it before.” James O’Donohew a planetary astronomer at the UK’s Reading University and one of the authors of the study. “But that means we have a new mystery in our hands now. How did Neptune get so cold?”

Neptune’s Strange Light Show detection may bring your answers closer.

“The Aurora is like a TV screen,” he said. Lee Fletcher a planetary scientist at the University of Leicester in the UK and one of the authors of the study. They said, “We are able to see the delicate dance of the magnetosphere processes.

Global protest to be held at 200 Tesla showrooms in opposition to Elon Musk

Protests are set to take place at Tesla’s showrooms across the US and internationally this Saturday. Organized under the name Tesla Takedown, these demonstrations have been growing in size since Donald Trump’s presidency began. Over 200 Tesla locations worldwide, with almost 50 in California alone, will be the sites of these protests.

The goal of the protestors is to oppose the actions of Tesla CEO Elon Musk and send a message to the Trump administration. They are critical of Musk’s decisions including laying off workers, cutting department budgets, making fascist gestures, and dismantling government agencies.

Vicki Mueller Orvera, one of the organizers of the Bay Area Tesla Takedown protests, emphasized that Musk’s actions are undemocratic. She sees Musk as an unelected billionaire wielding power in destructive ways.

The Tesla Takedown movement is described as a decentralized grassroots initiative protesting Tesla’s operations as long as Musk undermines public services. Local organizers are planning demonstrations independently.

Doge cuts allow Musk to cash in with SpaceX and Starlink contracts, ex-workers warn

Chase Musk’s revenue

Orvera urges protestors to take action by boycotting Tesla purchases, selling Tesla stocks, and participating in Tesla Takedown protests.

Despite requests for comment, Musk has not responded to the criticism against him. He has clarified his government efficiency work as improving government operations.

As Tesla Takedown momentum grows, Tesla’s financial performance has suffered. Since Trump took office, Tesla shares have plummeted, impacting Musk’s net worth significantly. Some Tesla owners have sold their cars following controversial statements and actions by Musk.

The protest movement has gained attention from both supporters and critics. Jonathan V Last, editor of Bulwark, has highlighted the impact of Tesla Takedown protests on Musk’s net worth and influence.

Protest movement grows

Tesla Takedown protests originated in February and have expanded to various American cities. Social media has played a significant role in mobilizing participants, with suspected attacks on Tesla showrooms being condemned.

Recent developments have led to the involvement of law enforcement in investigating the vandalism. Tesla Takedown organizers emphasize peaceful protests and distance themselves from any violent actions.

Anti-Tesla sentiment and protest Go global

The anti-Tesla sentiment and protests are not limited to the US but have also spread globally. Cities like New York and Chicago have seen regular Tesla Takedown protests with significant online support.

Organizers are ensuring that the protests remain non-violent and focus on sending a clear message against the actions of Tesla and its CEO. They are calling for widespread participation in upcoming protests across various international locations.

Planning Your Garden Considerating Climate Change

The quiet season is coming to an end.

During the winter there was a little bird gush to lift my heart. There are no occasional caw caw, chickadee dee of chickadee, big songs of little carolina rens that stay on our Pennsylvania farms throughout the winter, but no great horned owl courtship calls, nor wooden thrush or Baltimore orioles. Still, I was delighted with the music that was left behind.

However, we just heard the first notes of our first returning songbird, and with a red-winged blackbird, the snowdrop began to protrude from the ground.

The other day I forced their flowers to move last fall potted tulips and hyacinths from the unheated side of the barn into the warmth of the garden room. However, the vegetable garden is a puddle of icy mud, and the flowerbeds are still finely covered with leaves, showing little signs of life. The boxwood is covered in burlap and the snow fence is covered around trees and shrubs to prevent deer from being devoured.

The deer, which has changed from the color of milk chocolate to dark, breaks through the makeshift deterrent, eating Ee, Eunee Mauss, Treehouse, and this winter, Holly. The squirrels are running around joining their radar, but the chipmunks are still nowhere to be seen. I think they are in their dens that I think opossums, raccoons and bears are.

I’ve been waiting for a greenhouse, but now I’m hoping to hibernate in the winter and take a break from sowing, potting and growing. To walk through snowy forests and observe animal tracks, study ice patterns in the pond and make it seasonal. I would like to read in the Fire and Skilled Garden Catalog. Imagine what the garden will look like next year, and hope that next year will be better than last time, as all gardeners do. As Vita Sackville-West wrote in her poem, “The Garden:”

The gardener dreams of his own special alloy

Possibility and impossible.

But what is possible now? Looking back at last year’s terrible season, how do you adapt to the changes I witness?

A year ago, the winter was very warm, the shrub barely died, and last spring, a welcome sight dripping with leaves, but not normal. Spring was so hot that I missed out on a nice, cool window for the transplant. Early season, I didn’t know when to plant ruthless vegetables, and when to produce soft plants, not 85 degrees.

“After the danger of frost” is a general wisdom, but when is that? my Plant hardiness zone I’ve recently shifted as the coldest temperatures in my area are three degrees higher than in 2012. But even that new guidance didn’t help me.

Mid May felt like mid-June. It was then arriving on May 29th.

Anyway, I planted poppies in April (they like cool weather), but the seeds were washed away by the flood. There was a drought between June and November. The grass was brown. Dogwood and Tulip Poplar lost their leaves in July. My vegetable garden resembles a cracked riverbed. The soil was very hard and weeding was almost impossible.

The stream was dry so I saw deer walking into the pond and drinking for the first time in 36 years. Small food was available for them, so they distorted to our garage and ate deer-bearing lavender. Walking through the forest, I was impressed by the lack of growth underneath, especially the huge patch of nettle nettle from North American origin, the host plant for Admiral Akagi and the butterfly in Eastern Comma. Chanteles never bear fruit in normal places. I was worried that our spring would dry out.

Pennsylvania saw record wildfires in the fall. Usually, the two lilacs that appear in the spring bloom in October, and in late November I was harvesting something that I had not yet grown.

All of this reminds me of a radio show called “Piano Puzzlers.” My husband and I listen to it on Saturday mornings. Composer Bruce Adolf rewrites songs that are familiar to the classic composer’s style. He changes the tempo, harmony, or mode of the tune, and the contestants try to name the song and the composer. Imagine “a bit of a jude” in Brahms style. Somewhere in my brain, the song sounds familiar, but something is off. The music is misplaced. Sometimes I guess correctly. In many cases, it is not.

Climate change gardening is the same. Confusing and there are many speculations.

What should a home gardener do?

“The only predictable thing is that it becomes unpredictable,” said Sonja Skelly, director of education at Cornell Botanical Gardens in Ithaca, New York, “it was crazy too.”

Last spring was hot in Ithaca, so vegetable gardeners began planting two weeks before the frost-free date on May 31st. Extreme temperature fluctuations were then created, but the plants that just started were better as they were established. Things planted on the target day were stunted and were in poor growth period. “A good lesson,” Dr. Skelly said. The line covering that allows gardeners to get and grow plants later in the season “is really important in a climate like ours,” she said.

Covered crops such as millet, sorghum and black-eyed peas have been successful in botanical gardens. They improve moisture retention, reduce weeds, reduce erosion, and limit negative microorganisms in the soil. The birds love them, Dr. Skelly said.

She recommended planting together what the Haudeno Sauny people call three sisters, corn, beans and squash. The system produces better yields per hectare than any monoculture crop system, she said.

Drip irrigation is another solution, Dr. Skelly said. “It adds moisture where it is needed at the roots,” she said. The water is slowly released and remains laid down, and does not escape as with manual watering or using sprinklers.

“Observe, take notes, ask questions, ask for answers,” advised Dr. Skelly. “What are your neighbors watching?” I’ve been working on this issue for a while, learning through going to local botanical gardens, public gardens and nature centres. “Try to keep the information cycle running and talk to friends, family and neighbors as a way to help you understand it. That’s very important,” she said.

Dr. Skelly believes it is important for home gardeners to truly understand their plants. “Climate change may be a way to get to know our gardens much better,” she said. “We have to do it.”

For a long time I relied on experts who taught me how to garden responsibly. Do not harm the environment. I have learned to plant a variety of plants, including pollinator natives, and celebrate native weeds like Freeben. I’m practicing planting companions. I don’t spray pesticides or pesticides, and instead use compost, I make my own from comfrey and stinging nettles instead. I wish I could buy plants from something other than plastic.

But the more we contemplate gardening in an age of climate change, the more we believe our home gardeners must find many solutions for themselves. Much of gardening is trial and error, and unstable weather patterns mean that we must experiment more to do our own research. Essentially, we must become citizen scientists in our own vegetable patches and flowerbeds.

Cornell Botanic Garden has a garden for climate demonstrations, but in fact we all do. None of us had experienced this. And in the end, we’re all together. You will navigate a strange new world of digging the soil and growing things.

Tech Elite-backed California city stirs controversy with new development plans

In 2023, a group called California Forever funded by Silicon Valley billionaires, has introduced a flashy proposal to build a new city on tens of thousands of acres of farmland that has taken northeast of San Francisco.

The Solano County residents and officials, where the city sits, were dissatisfied with the lack of local opinions and concerns of wealthy outsiders with big plans to rebuild the area. California has forever changed its track after months of coverage and efforts to attract local leaders. They quickly tracked the plan and instead retracted voting measures that they had sought approval through the standard county process.

This month, California has been in the spotlight for a new proposal. And they were greeted much warmer, using the land they owned to create the shipbuilding hub. The Trump administration reportedly Presidential Order It will stimulate the US shipbuilding industry.

The company, which currently owns more than 65,000 acres in Solano County, said in a statement that Solano is “in its own craft to answer the call to rebuild our country’s naval power,” and that it can “promote economic revitalization” across the region.

“We are working very early in the process with elected officials and communities to explore ways to use these assets to support American sailors and stimulate economic growth in cities, counties and wider regions,” the company said in a statement.

Located about 60 miles from San Francisco, Solano County lives around 450,000 people and has a history of shipbuilding. It was the site of the first US naval base in the Pacific, operating for over 140 years. Today, the region’s largest employer is Travis Air Force Base, the country’s busiest, with over 10,000 people.

California began purchasing land within the county to sensitivity before it was made public with plans for the new city. They promoted efforts as a solution to California’s housing crisis, saying the new city has pledged to bring widespread new job opportunities for the area with its green infrastructure and a utopian vision of a walkable area, and that the project will not impose financial obligations or taxes on residents outside the community. However, they soon encountered a fierce pushback.

The Sierra Club’s local branch has stated that the company’s efforts include:Hostile takeover”. Last year, they withdraw the measures from the vote and agreed to an environmental report and development agreement on the project.

Meanwhile, last year, Joe Biden expressed interest in bringing shipbuilding back to the US, so the company was in touch with local officials expressing interest in pursuing such opportunities on the West Coast.

after that last week Edwin Okamura, mayor of the Solano County town of Rio Vista, announced that he met with representatives from California Forever and met with retired military leaders and other officials in the county to discuss the issue.

Vacaville mayor John Carli also visited the area and said he met with retired military officials who described the site as one of the most ideal locations in the United States and described the shipbuilding efforts there as a “unique opportunity.” Its site, California, has forever stated in its statement, with over 1,400 acres of land actively zoned for “maritime industrial use.” Carli said the manufacturing and assembly locations will be used rather than ports.

The effort is still in its early stages, officials said they are holding the executive order.

But so far, officials in the area have expressed enthusiasm for their efforts to expand the maritime industry. Alma Hernandez, mayor of Swissun, about 30 miles northwest of Collinsville, said in a statement that the city supports the expansion.


“Suisun City supports the local efforts to invite the US government and key defense contractors to invest in the future of Solano County,” Hernandez said. “Our area has a proud history of shipbuilding. It’s part of our identity. We are keen to contribute in every way to ensure maritime success in our area.”

Carli said the profits are far beyond shipyards and refer to more than $2.7 billion in economic impacts that air force bases have in the area. And he said that maritime industrial bases would benefit the air force bases.

With the history of shipbuilding in the region and the role it plays in the US defense, it makes sense to have this kind of project here, state Rep. Lori Wilson said, and that would bring great opportunities. Going forward, Wilson hopes the shipyard will become the largest employer in the county.

Wilson said he’s heard of the project from many members, but most of them were supportive. Given the level of distrust present in the organization, some have expressed concern about the environmental impact of the maritime industry and the role of California. Lawmakers were skeptical of themselves about the company.

“It’s something I’m careful about as a legislative representative in this area, but that’s not something I can deal with. It’s up to them to build trust.”

Still, even those who don’t support planning for the new city are interested in the project, Wilson said. “People are really excited about this opportunity. [the potential] For the shipbuilding to return to Solano County. There is a groundwell in support for this project and I am truly excited to do my part to make this happen. ”

Carli hopes the community will see beyond landowners. “We are confident that if the opportunity appears here locally, residents will recognize and support the project,” Kari said. “It deserves a thoughtful discussion with the community to understand that this is different from the city being proposed.”

Where and How to View the Partial Solar Eclipse in March 2025

There is currently another solar eclipse happening.

On Saturday, the moon will cast a shadow on the earth’s surface, creating a partial solar eclipse visible to some in the US, Canada, the Caribbean, Europe, Russia, and Africa. While not as spectacular as last year’s total solar eclipse in the US, it still offers a chance to pause from daily concerns and observe our position in the solar system.

During a solar eclipse, the moon appears to take a bite out of the sun, but the amount of coverage varies depending on the location. It’s important to note that cloud cover can obstruct visibility.

It’s never safe to view a partial solar eclipse without proper eye protection, as the sun’s surface will still be visible during the event.

The experience of a partial solar eclipse can differ based on location, with the extent of sun coverage and overall visibility varying. It’s also advisable to check local weather conditions for clear viewing.

NASA has released a schedule of solar eclipse times in various major cities here.

In North America, the eclipse begins early in the morning, with the sun mostly partially covered when it rises.

The upcoming solar eclipse will be visible in the northern hemisphere, spanning both sides of the Atlantic. Unlike a total solar eclipse, it covers a larger area of the sun with fewer defined paths.

Viewers along the northeast coast of the US will witness the most significant coverage of the sun during the eclipse. For instance, individuals in Boston may see 43% of the sun covered at 6:38am, while New York City will experience a 22% coverage. Further south, in Washington, D.C., there will be a minimal 1% coverage at 6:59am.

The most substantial sun coverage will occur further north, with areas like northern Quebec, Nunavut, and parts of Newfoundland and Labrador in Canada seeing over 90% of the sun covered by the moon.

Across the Atlantic, residents of Northern and Western Europe, as well as the northwest coast of Africa, will experience the solar eclipse in the late night or early afternoon. In northern Russia, the eclipse will occur in the late afternoon and in some locations close to sunset.

Eclipse duration can vary, with places like Halifax, Nova Scotia experiencing an eclipse lasting over an hour while Buffalo, with just a 2% coverage, will have a shorter duration of seven minutes.

A partial solar eclipse occurs when the moon moves between the Earth and the Sun, partially obscuring the sun from view.

Unlike a total solar eclipse where the sun is entirely covered, during a partial eclipse, only a portion of the sun is obscured. This occurs when the Earth, Moon, and Sun are not perfectly aligned. As a result, the sky does not darken enough during a partial eclipse to reveal stars and planets, and animals are unlikely to exhibit strong reactions.

A solar eclipse typically happens in pairs, two weeks apart, representing the time it takes for the moon to travel to the other side of the globe. Recently, stargazers witnessed a red moon during a full lunar eclipse earlier this month.

Staring at the sun, even for a few seconds, can lead to permanent eye damage as the retina lacks pain receptors. The same risk applies during partial solar eclipses. However, there are ways to protect your eyes while observing the event, such as using proper eye protection like eclipse glasses.

Be cautious of counterfeit solar eclipse glasses and viewers. To ensure safety, refer to a list of trusted suppliers compiled by the American Astronomical Association here.

If you’re unable to find eclipse glasses in time, there are alternative safe viewing methods, such as projecting the eclipse onto the ground using household items like cardboard or a kitchen strainer. The next partial solar eclipse is set to occur on September 21st, primarily visible in Australia, while a total solar eclipse is expected in the summer of 2026.

In addition to future solar eclipses, there are upcoming total lunar eclipses scheduled for September and March of next year, offering different celestial viewing experiences.

Car manufacturers faced with costly decisions due to Trump’s tariffs

President Trump’s new 25% tariffs on imported cars and parts have prompted automakers to consider various responses that come with financial implications, ultimately leading to higher car prices as analysts suggest.

Manufacturers may opt to shift production from countries like Mexico to the US, increase production of existing models made in the US, or cease sales of less profitable imported models. Regardless of the decision, consumers should expect to pay more for both new and used cars, with estimates indicating potential price hikes ranging from $3,000 to over $10,000 depending on the model.

In addition, potential additional tariffs announced by Trump could further impact car prices if implemented, especially in the midst of escalating trade conflicts.

The long-term effects of Trump’s tariffs on the automotive industry are expected to be disruptive and costly for American consumers, as noted by Michael Cusumano, a professor at MIT Sloan Management School.

Trump’s tariff threats, stated as permanent, have rattled automotive executives who hoped for negotiation leverage, leading to challenges in reshaping manufacturing and supply chains to comply with the imposed tariffs.

While Trump envisions tariffs as a strategy to revive American automobile manufacturing, the process of relocating production to the US involves substantial costs and complexities for automakers, potentially impacting prices for consumers.

The uncertainty surrounding tariffs has raised concerns among automakers about making long-term investment decisions, as the potential for policy changes under a new administration looms and could reverse current tariff implications.

While tariffs may incentivize choosing US-based production sites, consumer costs may rise as automakers prioritize compliance over manufacturing efficiency.

Major investment decisions impacted by tariffs could have substantial financial repercussions for companies, with potential risks if tariffs are subject to policy changes in the future.

Automakers may be cautious in passing on tariff costs entirely to consumers, as excessive price hikes could lead to reduced sales and revenue, potentially contributing to economic downturns.

In response to tariffs, some automakers have already raised prices, highlighting potential price increases for various car models as a result of imposed tariffs.

As the industry grapples with tariff impacts, automakers may explore strategies such as suspending sales of less profitable models and focusing on domestically produced vehicles to navigate the evolving landscape of trade policies.

Despite efforts to minimize tariff effects, most automakers rely on foreign-made parts, causing tariffs to impact overall vehicle costs and potentially leading to price adjustments across different car models.

As automakers navigate the challenges posed by tariffs, market dynamics and consumer responses could shape future decisions regarding production and pricing strategies in response to evolving trade policies.

Next Solar Eclipse: How to Watch the 2025 Partial Eclipse

Another solar eclipse is above us.

On Saturday, the moon casts a shadow on the surface of the earth. This is a phenomenon in which some people in the US, Canada, the Caribbean, Europe, Russia and Africa can experience it as a partial solar eclipse. As impressive as the total solar eclipse that crossed the US last year, but it’s an opportunity to take a break from secular issues and witness our place in the solar system.

During a solar eclipse, the moon appears to bite from the sun, but how much does it change depending on the location? And clouds can ruin your vision.

It is never safe to see a partial solar eclipse without protective eye gear, as the surface of the sun will not be completely obscured during this event.

People in areas where partial solar eclipses can experience it differently. How much sun is covered and what happens depends on where. You should also check your local weather report for clear or cloudy conditions.

NASA has published a list of solar eclipse times in several major cities here.

In North America, events begin early in the morning of sunrise, and are mostly already partially covered when the sun appears.

Saturday’s solar eclipse will be seen in the northern hemisphere, including both sides of the Atlantic. Unlike a total solar eclipse, it affects the wide area of the sun and has few clear paths.

In the US, viewers along the northeast coast will see the biggest solar eclipse. For example, people in Boston can see 43% of the surface of the sun covered at 6:38am in the eastern part. In New York City, the sun is eclipsed at just 22%, and those who are on the same south as Washington, D.C. at 6:46am experience a 1% solar eclipse at 6:59am.

The most blocked sun occurs much north. People in northern Quebec, Nunavut, and many of Newfoundland and Labradors in Canada witness more than 90% of the moon-covered sun.

On the other side of the Atlantic, people in Northern and Western Europe, and on the northwest coast of Africa, solar eclipses reach maximums in the late night or early afternoon. In northern Russia, solar eclipses occur late in the afternoon and in several places near sunset.

Eclipses can last for more than an hour in places like Halifax, Nova Scotia. The moon slowly glides over 83% of the sun, reaching its maximum point and retreat. However, in Buffalo, where the solar eclipse reaches up to 2%, it lasts just seven minutes.

The solar eclipse occurs when the moon glides between the Earth and the Sun, protecting all or part of the surface of the Sun from our field of vision.

The most dramatic version of this is the solar eclipse of the total sun when the entire sun is covered and its outer atmosphere, or when the corona is visible for a few minutes at the height of the event. This is known as the whole.

In contrast, on Saturday, only the mass of the sun is obscured, known as the partial solar eclipse. This happens when the Earth, Moon and Sun are incompletely aligned. Unlike the whole, the sky does not get dark enough during the partial solar eclipse to see stars and planets during the day. Animals are not likely to respond strongly.

The solar eclipse comes in pairs two weeks apart. It is the amount of time it takes for the moon to sway on the other side of the globe. The Stargazers recently saw the moon turn red and red during a full lunar eclipse earlier this month.

Even in seconds, staring at the sun can permanently damage your eyes. The retina has no pain receptors so you don’t feel it while it’s happening.

The same applies during partial solar eclipses. However, there are several ways to protect your eyes and still watch the event. If you save your paper glasses from gross solar power last year, they can be used again, provided they are not torn, scratched or damaged.

Beware of counterfeit solar eclipse glasses and solar viewers. You can find a list of trusted suppliers compiled by the American Astronomical Association here.

If it’s too late to find Eclipse Glasses, you can safely view the projection onto the ground using items around the house. Options include fashioning Eclipse Viewer from CardStock or cardboard boxes. You can also use a kitchen strainer, straw hat, or even your own fingers.

Another partial solar eclipse occurs on September 21st, the most common in Australia, according to NASA. A total solar eclipse occurs in the summer of 2026, which is visible on the top of the Northern Hemisphere.

If it’s too long and the wait is too long, then the two total lunar eclipses are also coming. One will be in September and the other will be in March next year. Unlike the total solar eclipse of the total sun only visible along the narrow path of the Earth’s surface, total erythema can be seen by most people on the night of the planet.

Is your phone causing distractions? Keeping it out of reach may not solve the problem

Smartphones can be distracted from other tasks

Phelings Media/Shutterstock

Can you scroll through at work and take a little care about your smartphone? One solution is to keep your phone out of reach, but unfortunately this doesn’t seem to work.

“People flip the phone over and hide it under the notebook. Sometimes you see a slightly fatal “throwing it over my shoulder” thing.” Maxi Heitmayer At the London School of Economics and Political Science in London. He previously studied phone use and found that people interact with their devices About every 5 minutes.

To see if this distraction could be avoided, Heitmayer and his colleagues recorded 22 college students and office workers, ages 22 to 31. One day, participants kept their phones within reach of their phones. Soon they kept their phones on a second desk, 1.5 metres away. In other words, I had to stand up to check it out.

Researchers found that volunteers spent an average of 23 minutes doing leisure activities over the phone on their first day, but 16 minutes, when the devices were even further apart. However, they were no longer working on the second day. Instead, participants spent more time running their activities slowly on their laptops, mainly on social media. “We use less mobile phones, but the whole thing that’s scrolling on social media is scrolling longer than we intended to move to a laptop,” says Heitmayer.

“This shows that distractions are not itself the device, but the underlying activity. daantje derks At Rotterdam, the University of Erasmus, Netherlands.

However, she points out that large-scale studies tracking people in a normal working environment are needed to verify these initial results. “This is an experimental lab study. People usually have others around and their lives are much more dynamic than this setup.

HHS discontinues research on vaccines and treatments for potential pandemics

The Trump administration has cancelled funds for dozens of research seeking new vaccines and treatments for Covid-19 and other pathogens that could cause a future pandemic.

The government’s rationale is that, according to internal NIH documents viewed by the New York Times, the community’s pandemic has ended and “provides a cause for the end of COVID-related grants.”

However, the research was not merely about Covid. 9 finished Award-funded center We will conduct research on antiviral drugs to combat so-called priority pathogens that could create an entirely new pandemic.

“This includes anti-viral projects designed to cover a wide range of families that could cause outbreaks or pandemics,” said a senior NIH official who spoke on condition of anonymity for fear of retaliation.

Vaccine research also didn’t focus on Covid, but on other coronaviruses that would one day jump from animals to humans.

Describing all studies as COVID-related is “completely inaccurate and merely a way to reduce infectious disease research,” officials said. Health Secretary Robert F. Kennedy Jr. said the NIH is focusing too much on infections, officials noted.

The funding suspension was first reported Science and Nature. The cancellation surprised scientists who relied on government support.

“The idea that there’s no need for further research to learn how to treat health issues caused by the coronavirus and prevent future pandemics is because “Covid-19 is over” is ridiculous,” says Pamela Bjorkman, a structural biologist at Caltech, who was studying the new vaccine.

The goal of the project was to prepare vaccines and drugs if a new pandemic hits it, rather than developing valuable months from scratch.

“In the last pandemic, we were really knocking down our pants,” said Paul Vienias, a virologist at Rockefeller University, working with Dr. Bjorkman.

“And unless you learn that lesson and prepare better for the next pandemic, you’ll rarely do better than last time.”

Dr. Beanius, Dr. Bjorkman and his colleagues were developing a vaccine that could protect them from a wide range of coronavirus species.

Researchers have discovered new strategies for caxing the immune system and learned how to recognize molecular features common to one or more viruses. The results of animal experiments were promising.

But now, their funds have been cut suddenly, and scientists say they doubted they could build on those outcomes. Dr. Vienias said the fire made him “angry, disappointed and frustrated.”

Other scientists were working on antiviral therapy, part of a program launched in 2021.

$577 million With support from the NIH, the lab’s nationwide network was studying how the virus was replicated and searching for drugs that could block them.

The researchers focused on the Viridae family, which contains the most worrying known pathogens, such as Ebola and Nipah virus. Scientists discovered many promising molecules and were moving forward towards clinical trials.

Reuben Harris, a molecular virologist at UT Health San Antonio, said the promising compounds revealed by the program include antiviral drugs that stop Ebola-related viruses from entering cells.

“We can deploy to help a lot of people quickly,” Dr. Harris said.

Several compounds appeared to work against many viral families. “We’ve seen a lot of experience in the world,” said Nevan Krogan, a systems biologist at the University of California, San Francisco.

On Wednesday morning, Dr. Krogan and dozens of colleagues gathered in the campus meeting room to confirm their results. And they also discussed what they could now, if any.

“One student asked me, ‘Well, I booked an experiment with this microscope tomorrow – can I do that?” “And I’m like, ‘Well, I don’t know.’ ”

Dr. Harris said that without ongoing support, the promising drugs he and others have discovered will not move into clinical trials. “It’s tragic – I don’t have too many words to explain it now,” he said.

In 2023, Kennedy said he wanted to take it. “break” From infectious disease research, instead focuses on chronic diseases.

Jason McClellan, a virologist at the University of Texas at Austin, was working on an antiviral drug program, but saw cancellations of pandemic research follow that promise.

Dr. McClellan, whose previous research was based on the creation of the 2020 Covid vaccine, said this week’s cuts made him wonder whether he could continue to study the pandemic in the United States.

“We’re starting to have conversations and plan to gather more information,” he said, noting the possibility of moving abroad.

“My lab is a structural virology lab focused on structural-based vaccine design,” he added. “If the focus is on chronic diseases, it doesn’t leave us much of a funding.”

EPA offers email option to bypass clean air regulations

The Biden administration has urged coal and oil-fired power plants to cut back on toxic chemical emissions, including mercury.

Today, the Trump administration is offering a special opportunity for businesses. By sending an email, you could receive permission from President Trump to bypass new restrictions and other major clean air regulations.

The Environmental Protection Agency announced this week that a vague section of the Clean Air Act allows the president to temporarily exempt industrial facilities from new regulations if the necessary technology is unavailable and if it is for national security reasons.

In notifications to businesses, the agency provided templates for seeking approval, including what to include in the subject line of an email. “The president will make a decision on merit,” stated a notice issued by the EPA on Monday.

Joseph Goffman, former executive director of the Harvard Law School Environment and Energy Law Program, expressed concern that President Trump is establishing a process that lacks scrutiny.

Goffman noted that government agencies typically set more specific standards for exemptions from regulations. He argued that Congress intended to include conditions in the Clean Air Act that would ensure some level of pollution control.

He stated, “It’s strongly indicated that decisions will be made on an ad hoc basis at best, as the provision doesn’t currently exist. This contradicts Congress’ intent, disregards the public health needs of affected communities, and goes against the EPA’s historical practices.”

EPA spokesperson Molly Vaseliou disagreed with this perspective, asserting that there is no explicit requirement for such conditions in the law. “This type of legal analysis seems in line with the responsibilities given,” she stated in an email addressing the interpretation of the law.

Under the latest policy, businesses can apply for up to two years of exemptions from various new restrictions on the emission of toxic substances like mercury and arsenic. This includes ethylene oxide, a carcinogen used in sterilizing medical devices.

Former New York Congressman Zeldin also mentioned that coal-fired power plants could seek exemptions from new regulations requiring them to address the health risks associated with coal ash, a toxic byproduct of electricity production through burning.

The EPA plans to eventually revise many of these same regulations, a complex process that will take time. While this process unfolds, companies are able to avoid complying with certain rules.

Critics like Pugh find it difficult to justify these exemptions, especially since the Biden administration had already identified feasible alternatives for the new rules. They also question the notion that contamination is in the national interest.

As of Thursday, it remained unclear whether companies had begun applying for exemptions, if any were granted, or if they would be made public. The deadline for applying for exemptions is by the end of the month, according to the EPA.

Alexa Lopez, spokesperson for the National Association of Manufacturers, expressed gratitude for the EPA’s consideration of exemptions for affected manufacturers. “NAM is prepared to collaborate with the administration to find a sustainable solution that protects the environment and supports manufacturers in global competition,” Lopez stated.

CoreWeave puts plans for IPO on hold

CoreWeave, a cloud computing company, was the first major publicly released artificial intelligence startup. When it submitted its public listing documents earlier this month, it signaled optimism in the volatile IPO market.

However, optimism has waned as CoreWeave, based in New Jersey, significantly reduced the size and value of its offering on Thursday. The company now plans to price its shares at $40 when trading opens on Friday. Submit The stock price is expected to range from $47 to $55 per share.

Initially, CoreWeave was expected to raise around $4 billion at a $35 billion valuation. However, the company is now aiming to raise $1.5 billion on Friday, valued at $19 billion.

The decline in offerings reflects a sluggish stock market, impacted by inflation and uncertainty surrounding President Trump’s tariffs. It also raises concerns about AI developments given the slowing economy, as evidenced by a 7% drop in Nvidia’s stock, a Coreweave investor, since Wednesday.

“It was a challenging time for the market overall,” said Samuel Kerr, head equity capital market analyst at financial insights firm Mergermarket. “This indicates a lack of appetite for risky transactions like this at the moment.”

While CoreWeave will be the first major AI company to go public, it doesn’t serve as a definitive test for AI products. It falls in line with standard startups in industries such as Openai and Anthropic, creators of popular chatbots.

Kerr also noted that CoreWeave has unique challenges that make it a challenging IPO candidate, such as significant debt required to build a new data center and its unusual background as a cryptocurrency mining company.

“Using it as a precursor to all AI is not particularly wise,” Kerr added.

CoreWeave, founded in 2017 by Michael Intrator as a cryptocurrency mining startup, currently has Brian Venturo and Brannin McBee, three former merchandise traders, as its top executives. The company has built its business around Nvidia GPUs for analyzing vast amounts of data.

Following a crash in crypto prices in 2019, CoreWeave doubled its supply of powerful chips by purchasing from struggling crypto companies. With the release of Openai’s Chatbot ChatGpt in 2022, CoreWeave shifted its focus to using chips for AI development.

As a public company, CoreWeave provides insight into the profitability of the cloud computing and AI sectors. While revenue surged from $229 million to $1.9 billion last year, the company has not yet achieved profitability. It spent nearly $1 billion to service its debt last year.

Based in Livingston, New Jersey, CoreWeave emphasizes its relationships with prominent California companies like Nvidia and Openai, who are investors in the company. An agreement has been announced valuing CoreWeave at up to $12 billion.

Having raised $2.3 billion in venture capital funding, CoreWeave was valued at $19 billion in the private market last year. Intrator, Venturo, and McBee collectively own about 30% of the company, with special shares granting them approximately 80% of the voting rights.

The largest investor in CoreWeave is hedge fund magnetor, who injected $50 million into the cloud computing startup in 2021, owning roughly 25% of the shares. Nvidia, the main supplier of CoreWeave’s chips, holds a 4% stake in the company.

The IPO was managed by Morgan Stanley, JPMorgan, and Goldman Sachs.

Possible connection between Kansas measles case and Texas outbreak

Last week, the measles cases in Kansas more than doubled to 20, with another outbreak in Ohio involving 10 people, as reported by local public health officials on Wednesday.

There have been several significant outbreaks in the US this year, including a large outbreak in West Texas with more than 320 cases and 40 hospitalizations. Health officials are concerned about the spread of the Texas outbreak to other areas.

More than 40 cases of measles have been reported in New Mexico, with seven identified in Oklahoma. Officials in both states have linked the infections to the Texas outbreak.

In Kansas, the virus is predominantly affecting vaccinated children in the southwest corner of the state. State health officials informed The New York Times on Wednesday that the genetic sequence suggests a connection to the outbreaks in Texas and New Mexico.

Fourteen other states reported quarantined measles cases in 2025, often linked to international travel. In Ohio, nine out of 10 cases were traced back to unvaccinated individuals who had recently traveled abroad.

Dr. Bruce Vanderhoff, the director of Ohio’s Department of Health, stated, “While we are disheartened by the measles outbreaks in Texas, New Mexico, and other states, we are not surprised to see some cases here in Ohio.”

Experts are concerned that low vaccination rates across the country have made it susceptible to the resurgence of preventable diseases like measles.

Less than 93% of kindergarteners received the measles, mumps, and rubella vaccine between 2023 and 2024, according to the Centers for Disease Control and Prevention.

Experts recommend a vaccination rate of at least 95% in the community to prevent outbreaks.

In Kansas, 90% of kindergarten children received MMR shots between 2023 and 24, according to state data.

About 89% of Ohio kindergarteners received the MMR vaccine that year.

Measles is highly contagious, spreading through coughing and sneezing when an infected person breathes.

Infected individuals can develop symptoms like high fever, cough, runny nose, and red, watery eyes within weeks of exposure. A telltale rash typically appears within a few days.

While most cases resolve within a few weeks, the virus can cause complications like pneumonia, especially in children, leading to difficulty breathing. Infection can also result in brain swelling, leading to permanent damage like blindness, hearing loss, and intellectual disability. According to the CDC, for every 1,000 children with measles, one or two may die.

One child died in the Texas outbreak, marking the first measles-related death in the US in a decade. Another suspected measles-related death was reported in New Mexico.

New York County Clerk refuses to accept Texas Court filings targeting doctors over abortion medication

The New York County Clerk recently prevented Texas doctors from taking legal action against New York doctors to provide abortion pills to Texas women.

This groundbreaking decision escalates the interstate abortion conflict to a new level, setting the stage for a legal showdown between states with differing views on abortion rights.

The dispute is expected to reach the Supreme Court, pitting Texas against New York. Texas has almost completely banned abortion. New York, on the other hand, has a Shield Law in place to protect abortion providers who supply medications to patients in other states.

Since the Supreme Court overturned the national abortion right in 2022, eight states, including New York, have implemented the Telehealth Abortion Shield Act. This law prohibits authorities from surrendering abortion providers to other states or complying with legal actions such as subpoenas.

The New York County Clerk’s action marks the first use of the Abortion Shield Act to oppose out-of-state judgments.

Dr. Margaret Daly Carpenter, based in New Paltz, New York, is involved in this case. She collaborates with telehealth abortion organizations to provide abortion medications nationally. Texas Attorney General Ken Paxton sued Dr. Carpenter in December for allegedly sending abortion pills to Texan women in violation of the state’s ban.

Dr. Carpenter and her legal team did not appear at a Texas court hearing last month. Consequently, Collin County District Court Judge Brian Gant issued a default ruling, imposing a $113,000 fine on Dr. Carpenter and mandating the sending of abortion pills to Texas.

Citing the New York Shield Act, Ulster County’s Deputy Clerk Taylor Brook refused to process Texas’ motion for enforcing the Collin County order. He also declined to file a subpoena demanding payment of the penalty and compliance with the Texas ruling.

“In accordance with the New York State Shield Act, I reject this submission and any similar future submissions,” Brooke stated in a release. “This decision may lead to additional legal action, and we must refrain from discussing specific case details at this time.”

Texas Attorney General Paxton has vowed to continue his efforts. He criticized New York for not cooperating in enforcing civil judgments against abortion providers who allegedly cross state lines with dangerous drugs.

Legal experts anticipate that Texas may challenge the Shield Act in New York state or federal courts next.

New York Attorney General Letitia James previously issued guidance to courts and officials statewide on adhering to the Shield Act’s requirements and restrictions.

“I commend the Ulster County Clerk for upholding the law,” James declared. “The New York Shield Act safeguards patients and providers from out-of-state attacks on reproductive rights. We must not allow anyone to hinder healthcare professionals from delivering essential care to patients. My office will always stand with New York healthcare providers and the individuals they serve.”

Texas became the first state to take legal action against abortion providers from other states using Shield laws. In a separate case, Louisiana also filed criminal charges against a Shield Act abortion provider earlier this year.

In the recent past, Louisiana officials requested Dr. Carpenter’s extradition, a request that New York Governor Kathy Hochul promptly rejected.

“We will not authorize the extradition request from the Louisiana governor,” affirmed Hochul.

Dr. Carpenter and her legal team have refrained from commenting on the Texas and Louisiana cases. The Abortion Alliance for Telemedicine, an organization co-founded by Dr. Carpenter, issued a statement expressing support for the Shield Act. “The Shield Act is crucial in ensuring access to abortion care regardless of location or financial status,” the coalition emphasized. “It upholds the fundamental right to reproductive healthcare for all individuals.”

The Telemedicine Abortion Shield Act has become a vital tool for advocates of abortion rights. Health providers in states where abortion is legal send over 10,000 abortion medications each month to patients in states with restrictive laws.

The Texas lawsuit against Dr. Carpenter accuses her of providing a 20-year-old woman with mifepristone and misoprostol, standard abortion medications used up to 12 weeks into pregnancy. Mifepristone blocks necessary pregnancy hormones, while misoprostol induces contractions akin to a miscarriage 24-48 hours later.

According to a complaint from the Texas Attorney General’s office, a woman nine weeks pregnant sought emergency care in July due to bleeding. The woman’s partner suspected that the miscarriage was induced by the woman’s mother and found abortion medications provided by Carpenter at their home.

During a court session in Colin County, Ernest C. Garcia from the Texas Attorney General’s Office revealed that the woman’s partner had lodged a complaint.

Return to Facebook’s origins with the New Friends tab integration

Last year, Meta CEO Mark Zuckerberg and one of his top EUs, Tom Allison, were discussing how to rebuild Facebook for the future of social networking.

Zuckerberg, who grew Facebook to a $1.5 trillion company renamed Meta from the dorm room project, wanted to regain some of the original rationales for social networks, or what he called the “OG Facebook” vibe, Alison said. After adding many years of features, executives felt that some of Facebook’s important features were dead.

So they asked themselves: Why not build some features similar to old Facebook?

On Thursday, Meta did it with a simple adjustment. The company now includes a separate news feed for users, featuring posts shared only by people’s friends and family.

A feature called The Friends tab replaces the app’s tab that displays new friends’ requests or suggested friends. Instead, Friends Tab will display a scroll feed of posts such as photos, video stories, text, birthday notifications, and friend requests. For now, Facebook users are only available in the US and Canada.

“We’re looking forward to seeing you in the facebook app,” said Allison, head of the Facebook app. “We’re making sure there’s still a place on Facebook for something like this, something you shouldn’t get lost in the modern social media mix.”

The new feed is a sudden departure from the way social media has evolved over the past decade. The rise of apps like Tiktok has become accustomed to seeing feed posts from influencers and content creators. Other companies followed suit. Meta’s apps, including Instagram, have begun to lean more towards recommended content to attract people for a longer period of time.

Now people see apps like YouTube, Instagram, Tiktok as something similar to TV.

Not everyone is welcoming shifts. When Zuckerberg founded Facebook in 2004, it was intended to help college students connect with friends on campus. As the app becomes more popular, it is now helping all users stay up to date with posts from friends and family.

So, when Zuckerberg announced in 2022 that Meta would insert recommended content on Facebook from people who were not connected to users, many users rebelled. Many people first discovered recommended content – it relied on surface suggestions – it was jarring. After some criticism, Zuckerberg slightly reduced the amount of such content added to people’s Facebook feeds.

Still, that didn’t stop meta from accepting algorithmically recommended content. In recent years, much of the people’s feed on Facebook and Instagram has been dominated by creators, businesses and brands. Recommended content, such as Meta’s video product Reels, has led people to spend more time on the app, the company said.

Meta has no plans to stop adding recommended content to users’ feeds, Alison said in an interview. For now, the company doesn’t think The Friends Tab is more popular than the recommended home feed.

And there could be more changes to Facebook. Meta is planning to bring in other features and updates to Facebook next year, making social media still “social,” Alison said.

“Frankly, it’s the heart of Facebook,” he said.

Psychology Accreditation Committee suspends diversity standards under pressure

The American Psychological Association, which sets the standards for professional mental health training, voted to suspend the requirement that graduate programs demonstrate commitment to recruitment and employment diversity.

This decision was made by accrediting bodies across higher education. Presidential Order President Trump signed by attacking diversity, equity, and comprehensive policies. It pauses the willingness to broaden the profession of psychology, disproportionately white and women, at a time of growing distress among young Americans.

The APA is the leading accreditation body for professional training in psychology and the only body recognized by the US Department of Education. It offers accreditation to approximately 1,300 training programs, including doctoral internships and postdoc residences.

Trump has made accredited bodies a specific target for his crusades against the DEI program; 1 Campaign Video “We will fire the radical left accreditor who allowed our university to be controlled by Marxist maniacs and madmen” and “accept applications for new accreditors.”

Justice Department officials have put pressure on accreditation agencies in recent weeks and warn the American Bar Association With a letter That they may lose their status unless they abolish the diversity order. ABA Voting in late February In Hang Law school diversity and inclusion criteria.

Concessions by the APA, a fortress of support for diversity programming, are specific landmarks. The association has been a central focus of its work in recent years, with the aim of fighting racism in 2021. Solved In particular, I apologize for its role in perpetuating racism by promulgating eugenic theory.

Aaron Joyce, accredited senior director at the APA, said the decision to suspend diversity requirements was driven by a “large influx of concerns and inquiries” from programs that are concerned they could withstand the president’s orders.

He said he was worried that institutions were often instructed by their legal advice to stop diversity-related activities, which would put their acquiescence at risk.

“The committee does not want to list the program in the danger of not being present due to a dispute between institutional guidelines and standards of recognition,” Dr. Joyce said.

He did not explain the tally of the March 13th vote. “It was an easy decision and not taken lightly,” he said. “Understanding personal and cultural diversity is a central aspect of psychological practice.”

The committee chose to maintain another diversity-related standard. Programs should teach trainees to respect cultural and individual differences in order to effectively treat patients. In reviewing each standard, the committee measured weights “those that put the program in a compromised position” against “something essential to psychological practices that cannot be changed.”

Kevin Cochley, a professor of psychology at the University of Michigan, said this week he was “absolutely devastated” to learn about the APA’s decision on psychology listserves.

“Frankly, I think this decision is truly ruthless given that we know the importance of having a diverse mental health provider,” Dr. Cochley said. “We don’t know how the APA can make these kinds of decisions, but we still think we are maintaining the highest standards of training.”

He said he believed the APA had acted prematurely and could wait until he faced a direct challenge from the administration.

“I think there’s always a choice,” he said. “I think this is a classic example of APA engaged in predictive compliance. They started moving out for fear of what would happen to them.”

According to APA data, the psychology workforce is disproportionately white. In 2023, over 78% of active psychologists were white, 5.5% were black, 4.4% were Asian, and 7.8% were Latinos. (The general population is about 58%, with 13.7% black people, 6.4% Asians, and 19.5% Latinos.)

In contrast to demographic collapse for doctoral graduate students, the programme is nationally aligned. According to APA’s 2022 data, 54% of doctoral students were white, 10% black, 10% Asian, and 11% Latinos.

John Dovidio, Yale’s professor emeritus in psychology and author of Unequal Health: Anti-Black Racism and the Threat to American Health, said the APA focuses on diversity in recruitment.

“It’s really something the department takes very, very seriously,” he said. “I’ve personally seen the impact.”

The memorandum of understanding announcing the decision is described as “a temporary lawsuit while awaiting further court guidance” regarding Trump’s executive order, upheld by the federal court of appeals on March 13. The order says, “litigation is currently law.”

Cynthia Jackson Hammond, chairman of the Council on Higher Education, which coordinates more than 70 accredited groups, said receiving direct orders from the government was “unprecedented.”

“The government and higher education have always worked independently and have worked sincerely with each other,” she said. “All we’ve had throughout the decades is healthy separation up until now.”

The federal government began to play a role in post-World War II accreditation as veterans flooded universities under the GI bill. The accreditation bodies are regularly reviewed by the National Advisory Committee on Institutional Quality and Integrity and advise the Secretary of Education whether they will continue to recognize them.

But government officials have never used the leverage to impose ideological orientation on higher education, Jackson Hammond said. She said recruitment diversity remains a serious challenge for higher education, so the standards are still very commonly used.

“Given what our institutions look like before, it could be a barometer that we see when we’re not paying attention,” she said.

Los Angeles Sheriff to Re-Test 4,000 DNA Samples Following Possible Errors

Around 4,000 DNA samples have been retested by the Los Angeles County Sheriff’s Department after the discovery of several test kits used last year. Officials have noted a potential pattern of “intermittently low performance” in early 2025.

The department received a warning from the test kit manufacturer on August 28 last year, but the notice was mistakenly directed to an individual not employed by the department, causing a significant delay in addressing the issue.

It was recently revealed that the affected kits were in use for approximately eight months from July 2024 to February 2025. As a response, the department has initiated an internal investigation and reinforced existing policies and procedures to ensure the accuracy of scientific results.

The Sheriff’s Department emphasized that faulty test kits should not lead to wrongful identifications of innocent individuals. Despite the possibility of incomplete or suboptimal results from the affected kits, it is unlikely that misidentifications have occurred.

Sheriff Robert G. Luna stated, “We take the integrity of our criminal investigations and the reliability of forensic testing very seriously. We are committed to addressing this issue thoroughly, ensuring transparency, and taking immediate corrective actions to protect the accuracy of ongoing and future cases.”

The LA County District Attorney’s Office is also reviewing the case to make informed decisions based on the facts and ensure the integrity of the criminal justice process.

“Building and maintaining confidence in the outcomes is crucial as we work towards rectifying any circumstances that require improvements and ensuring the integrity of individual cases.”

The animation in ChatGpt’s Studio Ghibli-inspired style is exceptionally well done

Creating animated films like those by the renowned Japanese filmmaker Miyazaki Hayao is a meticulous process that cannot be rushed. The intricate hand-drawn details require time and attention, often taking years to complete.

Alternatively, ChatGPT offers the ability to transform old photos into Miyazaki-style artwork within seconds.

Many users have already utilized this feature following Openai’s update to ChatGPT, enhancing its image generation capabilities. Users can now see photos rendered in the Studio Ghibli style, evoking the essence of films like “My Neighbor Totoro” and “Spirited Away.”

Some users have shared Ghibli-style images on social media, ranging from selfies and family photos to memes. While some have used the technology to create renderings of darker images, like the 9/11 attacks or the murder of George Floyd.

Sam Altman, the CEO of Openai, humorously changed his profile picture to X’s. He jokingly mentioned the sudden rise in popularity of filters overshadowing his previous work.

A dietitian named Kouka Webb, residing in Tribeca, transformed her wedding photos into Studio Gibrick Frames. Having grown up in Japan, she found joy in stylizing herself and her husband in a nostalgic manner.

Webb shared one of these stylized photos on Tiktok and received criticism for using AI instead of human artists.

Some online users have raised concerns about the use of image generation technologies. Referring to a 2016 documentary where Miyazaki criticized AI as “an insult to life itself,” the recent surge in filters and AI art has sparked a debate.

As AI platforms gain more power and popularity, creatives including writers, actors, musicians, and artists express their frustrations about their work potentially being replicated.

In 2024, prominent figures like writer Ishikawa, actor Julianne Moore, and musician Thom Yorke signed an open letter criticizing the unauthorized use of creative works in AI models like ChatGPT.

The New York Times filed a copyright infringement lawsuit against Openai and Microsoft, alleging the unauthorized use of publicly available works to train AI.

Some users, like sculptor Emily Belganza, have used ChatGPT to create Ghibli-style photos from memes, expressing concerns about the impact of such technology on creative work.

Openai spokesperson Taya Christianson emphasized the platform’s efforts to balance creative freedom while taking a conservative approach to image generation updates.

Belganza mentioned her evolving thoughts on the integration of AI into society, acknowledging the need to adapt to these advancements while preserving artistic identity.

Rats making strides towards becoming snobbish and exaggerated

Feedback is the latest science and technology news of new scientists, the sidelines of the latest science and technology news. You can email Feedback@newscientist.com to send items you believe readers can be fascinated by feedback.

Rattus sommeliersis

Feedback has reached an age where even small amounts of alcohol make us sleepy. As such, the concept of wine tasting is not appealing. Taking a nap seems like a time-consuming and expensive method. However, fermented grape providers can quickly have a new demographic to cater to rats.

At least that’s something we extrapolate from our research. Animal cognition Called “Rats can distinguish (and generalize) two white wine varieties.”. It was released on February 21st, and sub-editor and television columnist Bethan Ackerley sent it to feedback on March 1st after it went “semi-visit online.”

Anyway, it’s actually very interesting. We all know that human smell sensations are considerably limited compared to other mammalian odors, including rodents. This is because there are few olfactory receptors in the nose. But we also know that our minds are more refined than the minds of animals. To raise the question: in animals, in this case, rats, can they integrate many olfactory signals with different olfactory signals and learn about complex categories such as different white wines, for example?

Researchers trained rats to distinguish between two grape varieties, Riesling and Sauvignon Blanc. To make sure they learned the categories, they tested them with new examples of these wines. Rats can convey the difference. Obviously there is quite a bit of happening between those rat ears.

The question is how far can you take this? It is one thing to show that rats can learn the difference in wine, but can they also learn to really look down on it? Feedback wants to list an increasingly ridiculous list of odors after seeing mice that can smell wine. Are they really wine lovers until these mice squeal about “really tasting Terroir” and “Liebfraumilch is not scary at all”?

Anti-war

At this point, feedback has heard too much about the imminent AI-induced apocalypse. Yes, yes, one day, one of the AI ​​companies will soon create artificial general information (AGI). This is as intelligent as humans. AGI is something that intelligent beings can easily do to themselves (shush, don’t ask), and they start redesigning to become even smarter as they quickly become unstoppable. At that point, humans are either reduced to or wiped out by animals in the zoo. It is said that this is so important that we should stop worrying about stinging things like climate change. you know.

It was this mental framework that gave us feedback. New science fiction short stories By Madison Stoff. You can’t tell the name of the story. Because it uses sarcasmically the words that are stopped by email filters, but you can quote Stoff’s explanation. “A very entertaining, intimate science fiction story reinterpreting the memes of Loco’s Basilisk through a medium of pseudo-erotic self-insertion fan fiction.”.

At this point, imagine that readers may have one or two questions. Don’t be afraid: Feedback is here to guide you.

Roko’s Basilisk is a kind of thought experiment with AI. In the distant future, the AI ​​decided to punish all humans who knew it could exist but did not help create it. AI creates digital replicas of all those people and tortures them forever. This is how this future AI will encourage us all to start building it now. If we do that, we will not be replicated and tortured.

Don’t look at the title “basilisk” as it is a reference to a mythical creature that can kill you at a glance. Similarly, knowing the idea of ​​Roko’s basilisk is probably putting you at risk. Just reading the feedback this week, you may have denounced your own future replica of yourselves for eternal suffering. very sorry.

Stoff’s story tells how to save humanity from Roko’s basilisk in the distant future by seducing it using her sexual wil. Basilisk is so troubled by her that she agrees to stop torture everyone in exchange for this passionate encounter. Additionally, Stoff wrote a short story about this and brought it online, so it’s part of Basilisk training data. This means that if a basilisk exists it’s burning to Madison Stoff.

Simply reading and sharing stories, feedback is more likely to make future AI attracted to Stoff, and less likely it would torture us all. We encourage our readers to do the same, and there is a warning that there is clear sex in the story. And don’t read it at work unless you work for an AI company. In that case, proceed immediately.

Tesla? I barely knew her!

Occasionally, when Elon Musk appears in the news, feedback is an indescribable reminder of the 1818 sonnet Ozymandias. It’s strange how the mind works.

Anyway, posted by Carmaker Kia’s Norwegian branch Advertise on Instagram It features a bumper sticker showing one of the electric cars and saying, “I bought this after Elon got hooked.” Apparently This is not centrally approved And since the ads have since been removed, it would be a real shame if someone started making these stickers.

Have you talked about feedback?

You can send stories to feedback by email at feedback@newscientist.com. Include your home address. This week and past feedback can be found on our website.

What Happened After These Indie Smash Hits?

IT is more or less impossible to put accurate numbers into the number of video games released each year. According to
Published data, About 19,000 titles were released in 2024 on Digital Store Steam. This is on one platform. Hundreds of more have arrived on consoles and smartphones. In some respects, this is a positive sign of a vibrant industry, but how do you notice an entirely new project? When Triple A titles with a multi-million dollar marketing budget find it difficult to attract attention (Dragon Age: Bailguard, Final Fantasy VII Remake, and EA Sports FC have reported disappointing sales), is there a chance that a small team will break out?

Still, that happens. Last year’s surprise hit Baratoro shifted copies over 5m. Title Manor Rhodes, a complex medieval strategy, sold 1 million copies over the weekend. But what awaits a small developer after they succeed? And what does success mean in an ever-evolving industry?

James Carbutt and Will Todd of Coal Supper are still trying to figure it out. Their Aselvic satire will appreciate you being here!, players have gone through the strange quote scenarios of the fictional humble north town of Barnesworth, and are now an award-winning game. “It’s not registered as a success in my head at all,” Carbutt says. “The numbers were up on the screen, there was a YouTube playthrough and some erotic fan art. Beyond that, I won’t subscribe.”

After working on the project for three years, the pair now notices the confusing glare in the spotlight and asks questions about: “That’s scary,” joking Carbbit. “But we don’t think we’ll feel any kind of second-time out syndrome. The space where we can be a bit more introspective about what we want to do next is an interesting habit of successful indie games.”

Veteran indie developer Gabe Cuzzillo (Ape Out, Baby Steps) offered them the wisdom of the wise man. “He talked about not just about making something, but how to focus because it’s amorphous,” Todd says. “Instead, look at what we essentially want to explore and judge success based on whether we have explored it or not. The speed pressure on the market doesn’t apply to us.

Australian developer Grace Bruxner redefines success after leaving behind a trilogy of Bitize Size Adventures, which was developed in collaboration with Frog Detective Games: Thomas Bowker.

“Success in the game has always been a bit of a lie and a bit of a illusion,” she says, pointing to typical markers such as cultural influence, number of players and financial gain. “Did the measure of my success create something I’m proud of and it has impacted my life and the lives of others in a positive way? And it was.

Bruxner began working on the series as an experiment in his final year at university to see if he could create a commercial game. After a relatively refreshing first outing, the second frog detective game demanded that Bruxner and Bowker lock in, spending most of their time on the project. In the third article, pressure was beginning to fall victim to, but the hard work paid off. Throwing out the pandemic as well as mental and physical health issues, Brooksner was ready to take a break. “I wasn’t crushed very hard, but I wasn’t having a great time either,” she says. “It was really good to make that choice.”

Bruxner still has the idea of ​​a game that swirls around the back of her head, but she wanted to escape the endless production cycle that swallowed many of her mates, regardless of fatigue or burnout. “That’s not universal advice,” she says, “But if you’re a solo developer or a really small team, I don’t think there’s any shame to leave there. Unless you like making games, I don’t love making games.

Three years after the series’ swan song, she falls into an indefinite break, exploring alternative creative paths such as pottery. “I can’t imagine making a game because I am expected of me as a creator,” she explains. “I don’t even know where I’m going from here.”

Bruxner is amazed at his ability to maintain himself with the modest amounts offered by Frog Detective. “If the game keeps its tail and can live within its own means, it will lead to passive income that is not linked to being a scary landlord,” she explains. Still, she knows how taboo it is to talk about money explicitly, especially in creative circles like the indie gaming scene. “I have free time to chill and decide what I want to do, but at some point I think I need to have a career again. My biggest question is, will this money last forever? Perhaps not.

It may seem like more indie items have fallen into the spotlight in recent years than ever before. However, the persistent turbulence in the gaming industry has become even more complicated by finding financial support for follow-up. “The elephant in the room is everything that’s happened over the past few years, evaporating a ton of layoffs, studio closures and funding opportunities,” says upcoming indie developer AP Thomson, who will consume me alongside fellow NYU arcade alumni Jenny Ziao Hosia. “Before that, there was a pretty big change in the mid-2010, when indie publishers and funders began to rise to prominence. Everything we’ve heard suggests that the same opportunities are no longer present or are incredibly limited.”

Consumes Me, the duo’s adult scheduling RPG has no release dates, but has been nominated for five gongs at the Independent Game Festival Awards. As such, Jiao Hsia and Thomson are already under pressure to decide on their next effort. “Several people have said that once it’s released we should move forward,” Thomson says.

Even with high expectations, the pair are not keen to move ahead of them. “Everything we’ve heard suggests that now is not the best time to pitch, so we focus our energy on the launch and then read the temperature in the room,” adds Thomson.

“I don’t feel like I have to show up at a job I’ve never applied to, I want to enjoy making art again,” explains Jiao Hsia. “The idea of ​​creating art for fun without worrying about making money is something I can’t wait for.”

Democrats remove Trump-appointed FTC chair

President Trump is being sued by two former Democratic Federal Trade Commission (FTC) commissioners for firing them, alleging it was an illegal executive overreach. Trump dismissed commissioners Rebecca Kelly Slaughter and Alvaro Bedoya on March 18, disrupting the bipartisan setup of the agency. In a U.S. District Court lawsuit, Slaughter’s and Bedoya’s lawyers claimed that their removal violated federal law. They referenced a 1935 Supreme Court precedent stating the president cannot fire members of an independent regulatory commission solely due to policy disagreements.

The White House did not respond immediately to requests for comment, previously asserting that Trump has the authority to manage administrative personnel. This lawsuit is part of a larger legal battle over Trump’s expansion of his powers, with over 50 court decisions temporarily halting his administration’s actions. The fight also extends to regulators who are meant to be independent of direct White House control.

Slaughter and Bedoya’s lawsuit named two Republican FTC commissioners and the agency’s executive director as defendants. They cited the 1914 law protecting commissioners from arbitrary removal, reinforced by Supreme Court rulings. Trump’s attempts to exert control over regulatory agencies have faced backlash from legal challenges.

Trump signed an executive order affecting several agencies, requiring proposed regulations to be submitted to the White House for review. This move tightens the White House’s grip on agency operations. Despite legal battles, Trump continues to assert his authority over regulatory bodies.

The FTC, involved in high-profile cases against tech giants like Meta and Amazon, faces ongoing disputes regarding corporate practices and antitrust issues. With a focus on online platforms, the FTC is navigating complex legal challenges under Ferguson’s leadership.

In a letter, the White House argued that the Supreme Court’s protections for FTC commissioners do not apply to current leaders. The lawsuit highlights the ongoing struggle between Trump’s administration and independent regulatory bodies.

The lawsuit alleges that Slaughter and Bedoya were abruptly removed from their positions at the FTC without justification. Their legal battle exemplifies the broader conflict over the administration’s attempts to exert control over regulatory agencies.

The lawsuit filed by Slaughter and Bedoya sheds light on the power struggles within the FTC and the broader implications of presidential authority over independent regulatory bodies.

The FTC’s battles with tech giants and corporate entities underscore the agency’s critical role in regulating antitrust practices and protecting consumers. Under heightened scrutiny, the agency’s actions reflect the evolving landscape of online platforms and corporate accountability.

Facebook returns to its origins by prioritizing posts from friends and family

Last year, Meta CEO Mark Zuckerberg and one of his top EUs, Tom Allison, were discussing how to rebuild Facebook for the future of social networking.

Zuckerberg, who grew Facebook to a $1.5 trillion company renamed Meta from the dorm room project, wanted to regain some of the original rationales for social networks, or what he called the “OG Facebook” vibe, Alison said. After adding many years of features, executives felt that some of Facebook’s important features were dead.

So they asked themselves: Why not build some features similar to old Facebook?

On Thursday, Meta did it with a simple adjustment. The company now includes a separate news feed for users, featuring posts shared only by people’s friends and family.

A feature called The Friends tab replaces the app’s tab that displays new friends’ requests or suggested friends. Instead, Friends Tab will display a scroll feed of posts such as photos, video stories, text, birthday notifications, and friend requests. For now, Facebook users are only available in the US and Canada.

“We’re looking forward to seeing you in the facebook app,” said Allison, head of the Facebook app. “We’re making sure there’s still a place on Facebook for something like this, something you shouldn’t get lost in the modern social media mix.”

The new feed is a sudden departure from the way social media has evolved over the past decade. The rise of apps like Tiktok has become accustomed to seeing feed posts from influencers and content creators. Other companies followed suit. Meta’s apps, including Instagram, have begun to lean more towards recommended content to attract people for a longer period of time.

Now people see apps like YouTube, Instagram, Tiktok as something similar to TV.

Not everyone is welcoming shifts. When Zuckerberg founded Facebook in 2004, it was intended to help college students connect with friends on campus. As the app becomes more popular, it is now helping all users stay up to date with posts from friends and family.

So, when Zuckerberg announced in 2022 that Meta would insert recommended content on Facebook from people who were not connected to users, many users rebelled. Many people first discovered recommended content – it relied on surface suggestions – it was jarring. After some criticism, Zuckerberg slightly reduced the amount of such content added to people’s Facebook feeds.

Still, that didn’t stop meta from accepting algorithmically recommended content. In recent years, much of the people’s feed on Facebook and Instagram has been dominated by creators, businesses and brands. Recommended content such as Meta’s video product, Reels, has led people to spend more time on the app, the company said.

Meta has no plans to stop adding recommended content to users’ feeds, Alison said in an interview. For now, the company doesn’t think The Friends Tab is more popular than the recommended home feed.

And there could be more changes to Facebook. Meta is planning to bring in other features and updates to Facebook next year, making social media still “social,” Alison said.

“Frankly, it’s the heart of Facebook,” he said.

The Impact of Trump on Auto Prices: How Major Auto Brands are Affected

President Trump announced tariffs on automobiles and auto parts on Wednesday, impacting U.S. and overseas automakers.

Each company has different vulnerabilities based on their circumstances.

Tesla, led by Elon Musk, sells cars from its U.S. plants, potentially making it less exposed to tariffs.

However, Tesla sources parts internationally, with about a quarter of the car’s value coming from overseas.

Tesla’s global sales are declining, partially due to Musk’s political activities, making it a target for retaliation against Trump’s tariffs in some countries.

GM, America’s largest automaker, imports many popular vehicles, potentially making it vulnerable to tariffs.

Despite strong profits, GM relies on overseas assembly for around 40% of its U.S. sales, which could be impacted by tariffs.

Ford is less reliant on imports, with most vehicles sold in the U.S. being domestically produced.

However, Ford still depends on foreign factories for key components like engines.

Stellantis, formed by the merger of Fiat Chrysler and Peugeot, is facing sales challenges and CEO transitions, putting it at risk.

Toyota, like other Japanese automakers, sells a significant number of cars in the U.S. but manufactures many vehicles overseas.

Despite the dependence on foreign production, Toyota is considered one of the strongest global automakers.

Volkswagen, with limited U.S. factories, imports many vehicles, potentially impacting its operations.

Volkswagen has faced financial struggles, especially with declining sales in China and the rise of domestic electric vehicles.

Both Korean companies have seen growth in U.S. sales and are investing in local production to avoid tariffs on certain models.

Hyundai and Kia continue to import cars into the U.S., facing potential tariffs despite their investments in local manufacturing.

What is Vibe Coding and Is it Important to Use AI?

Do you want to get AI to write software for you? It’s coding of the atmosphere

ronstik/alamy

I want to write software, but do you have a first clue as to where to start? Enter “Vibe Coding.” This is the term that swept the Internet to explain the use of AI tools, including large-scale language models (LLMS), such as ChatGPT, to generate computer code even when it is not programmable.

What is atmospheric coding? Where did it come from?

“Vibe coding basically refers to using generated AI to generate the entire code for your app, not just to assist with code.” Noah Jansilaksa at Bentley University in Waltham, Massachusetts. Users will ask or ask for LLM-based models such as CHATGPT, CLAUDE, COPILOT, etc., to prompt, write code for the app or service, and the AI system will do all the work.

The term was coined by Andrej Karpathy, the head of AI at Tesla and founding engineer at Openai, the manufacturer of ChatGpt. February, he Posted on x “A new type of coding” is called “vibe coding.”

Karpathy explained that “we give in completely to the atmosphere, accept exponential functions, and even forget that the code exists.” The term was born and ideas were established. “It captured a moment that resonated with so many people because there are so many people who are non-programmers who can start playing with LLMS, write code and get great results from them,” says software developer Simon Willison.

What are the key points of coding the atmosphere?

Software engineering is difficult to learn. As a result, many people don’t care. Vibe coding helps people with ideas for tools, apps and services without the challenge of learning the details of programming languages.

“On the one hand, it’s a game changer. Many people say it’s coding the atmosphere, and in the course of some encouragement cycles, it’s better than what you can do for those who can’t programme, which is amazing.” Matt wood At Northumbria University, UK. But it can also lead to software that is incomplete and scattered with errors, he adds.

So is a vibrator a good or bad thing?

Opinions are divided. “All of these people have made the outrageous claims on LinkedIn and Twitter that no one needs to learn to program,” says Willison, who thinks it’s an exaggeration to the power of coding in vibes.

“My feeling is that this is a promising direction that’s going to get much better and we’ll see more in the near future, but it’s a bit limited now and there are some reliability issues,” says Giansiracusa. The code created is often buggy. The people who are urging it don’t have the inherent knowledge to fix it, and therefore rely too much on the same LLM who made the error to fix them.

Does Vibe Coding change software engineering?

One of the big claims about AI is its ability to take on our work. However, despite some social media boasting, there is little evidence that vibe coding will replace software engineers. “We’re not going to replace programmers,” Wood says.

“I feel that the job of a software engineer is to create software that works,” Willison says. “One of the reasons why we don’t think these systems will leave us out of our work is that in reality the vast amount of work done by software engineers has nothing to do with entering the code.”

Our first encounter with Aurora on Neptune

Green spots show where the aurora brightens the sky in Neptune

NASA, ESA, CSA, STSCI, Heidi Hammel (Aura), Henrik Melin (Northumbria University), Leigh Fletcher (University of Leicester), Stefanie Milam (NASA-GSFC)

For the first time, researchers discovered infrared aurora swirling in Neptune’s atmosphere, examining decades of scientific speculation.

When NASA’s Voyager 2 mission was flew by Neptune in 1989, I found an appetizing hint of aurora activity in the clouds of Ice Giant. However, scientists were unable to verify the phenomenon at the time because existing equipment was too weak. Now, James Webb Space Telescope (JWST) has finally provided the power to detect them.

“This really was a fulfillment of long-standing expectations.” Heidi Hammel Washington, DC, Astronomical Research Association.

Hammel and her colleagues used NirSpec from JWST, a powerful infrared imaging tool, to capture spectral images of Neptune and analyze light at various wavelengths emitted by the planet. In 2023, researchers used musical instruments to detect Uranus’ infrared aurora. This time I found it on Neptune too.

The images allowed Hammel and her team to begin building a map of Neptune’s magnetic field. This is particularly exciting as the planet is known to have some of the rarest magnetic poles in the solar system.

Unlike Earth, Jupiter, and Saturn, Neptune’s magnetic poles are not at the center of their rotating poles. Instead, “they are offset by almost half the planet’s radius,” says Hammel. As a result, the aurora appears as an irregular mass far closer to the equator.

In addition to detection of Auroras, observations of JWST showed that the ionosphere of Neptune, a layer of charged particles that covers several planets, was cooled. Now, on average, it’s about 10% colder than when the Voyager 2 passed 34 years ago. A similar change was detected on Uranus.

The authors of the new study are unclear why this cooling occurred, but they hope that the upcoming JWST observation period, scheduled for 2026, will provide more clues.

John Green’s Constant Battle with Tuberculosis

Noren: The initial patient with tuberculosis I encountered in Nairobi had an advanced form of drug-resistant tuberculosis (XDR-TB). The chances of the known cure being effective for him were very slim. Despite this, he remained optimistic as he received his Delamanid medication daily. Unfortunately, it was eventually out of stock.

Green: Oh my god.

Noren: I told him, “This situation is terrible for you, Barak. It’s also scary for your wife and five children.” Thankfully, they were screened and found to be TB-free. However, due to his illness, he was bankrupt and had to send his family to live in the village.

XDR-TB not only poses a threat to him and his family but also to everyone in close proximity to him. Living in close quarters with 500 other individuals increases the risk for all involved.

Green: Yes, this is a tragic situation that affects many individuals on a global scale. It’s a crisis for human health worldwide, as antibiotic resistance becomes a serious concern.

Without effective tools to combat tuberculosis, we risk regressing to a time when the disease was rampant and deadly. Personal stories from the past, like my great uncle’s death from tuberculosis, serve as a stark reminder of the consequences.

Noren: Could this happen in the US?

Green: Yes, the US has seen a rise in tuberculosis cases, with around 10,000 active cases reported this year. The lack of robust public health systems and access to treatment contributes to this increase.

Noren: Why is this happening?

Green: Our inadequate public health infrastructure and insufficient treatment options are major factors in the rise of tuberculosis cases. We need to address these issues to prevent further spread of the disease.

Noren: We have the knowledge to create a world free from tuberculosis, yet we fail to act. Why do you think we are complacent in this regard?

US terminates vaccine funding for underprivileged nations

The Trump administration plans to discontinue US financial support for Gavi, an organization that has been instrumental in purchasing crucial vaccines for children in developing nations. Gavi has saved millions of lives over the past 25 years and has significantly expanded its efforts to combat malaria, which is one of the leading causes of death worldwide.

It has been decided that the administration will continue its major drug subsidies for HIV and tuberculosis treatments, as well as maintain food aid for countries experiencing civil wars and natural disasters.

These decisions were outlined in a 281-page document sent to Congress on Monday night by the U.S. International Development Agency, detailing foreign aid projects that are expected to be terminated. Copies of spreadsheets and other documents describing the plan were obtained by The New York Times.

The document portrays the US as a compassionate ally, highlighting the significant scale of the withdrawal from longstanding efforts and emphasizing the commitment to leading the fight against infectious diseases that claim millions of lives each year.

The cover letter provides details on the reduction of funds to USAID, with a significant portion of its budget being cut and only 869 out of over 6,000 employees remaining.

The administration has decided to continue 898 USAID awards while terminating 5,341, according to the letter. The value of the remaining programs is reported to be up to $78 billion, with $8.3 billion still available for disbursement. This suggests a substantial $40 billion reduction in annual USAID spending.

A State Department spokesperson overseeing the remainder of USAID confirmed the accuracy of the termination list, stating that each award was reviewed based on agency priorities and if deemed inconsistent, it was terminated.

The memo presented to Congress portrays foreign aid as a unilateral decision. However, there are questions about the administration’s legal authority to terminate these programs, as spending on specific health initiatives is typically allocated by Congress.

Several programs, including funding for the UN Food and Agriculture Organization and efforts to combat malaria, have been terminated.

Sierra Leone’s health minister, Dr. Austin Demby, expressed concern over the termination of US funding for Gavi, emphasizing the impact on children’s health globally.

He highlighted the importance of Gavi’s support in purchasing vaccines and providing critical aid, particularly during outbreaks such as MPOX.

Dr. Demby urged the US government to reconsider its decision, emphasizing that investing in Gavi is essential for global health security.

Gavi has been credited with saving the lives of 19 million children since its inception 25 years ago, with the US contributing 13% of its budget.

The termination of the grant to Gavi, valued at $2.6 billion until 2030, could have serious consequences for vaccine distribution in low-income countries.

The loss of US support may lead to a significant reduction in Gavi’s ability to provide essential services, potentially impacting millions of children who rely on vaccinations.

Gavi’s estimates suggest that without US funding, 75 million children may not receive routine vaccinations in the next five years, resulting in over 1.2 million deaths.

The United States has been a key donor to Gavi and has played a crucial role in supporting the organization, particularly during the Covid-19 pandemic.

Dr. Sania Nishter, the CEO of Gavi, expressed hope that the Trump administration would reconsider its decision to cut support, emphasizing the importance of Gavi’s work in protecting global health.

Vaccinations provided by Gavi not only safeguard individual children but also reduce the risk of major disease outbreaks. Gavi maintains a global stockpile of vaccines against diseases such as Ebola and cholera for rapid response efforts during outbreaks.

While the administration has indicated that the foreign aid review process is complete, there is still funding available for some programs to continue. However, there have been significant reductions in malaria response efforts, impacting vulnerable populations in countries like Cameroon and Tanzania.

The memo also highlights staffing changes at USAID, with some employees being placed on administrative leave or terminated, raising concerns about the agency’s operational capacity.

Shark sounds captured in groundbreaking recording

Dolphin’s mouth. The whale sings. Fishcloak, chirp, Grant, ham, groans. However, in sea chatting, up until now, one voice was missing.

Sharks have long been considered quiet killers of the water. However, scientists at the University of Auckland in New Zealand recently recorded a rig shark, or Mastel Slenticratus, to create a sharp click by combining the teeth, according to findings published in the journal. Royal Society Open Science on Wednesday. They believe this is the first time a shark has actively made noise.

Chief investigator Karolyn Nieder was the first to hear the sound while studying the shark’s hearing abilities. While she was dealing with one shark, it clicked and snapped a similar sound to the sound of an electric spark, she said.

The noise came from the Rig shark, a rather small shark common in waters around New Zealand. It grows up to 5 feet and feeds mainly on crustaceans. It is eaten by larger shark species and New Zealanders who use it to make fish and chips.

Dr. Nieder was surprised when he heard the noise.

Other sea creatures have mechanisms to make noise. For example, fish have a gas-filled sac, a swimming bladder, which is used for buoyancy but can be used as a type of drum. Many fish have muscles that can vibrate the swimming bladder in a manner similar to the human vocal cords.

However, the sharks were “thought to be silent and could not actively produce sound,” Dr. Nieder said.

In this study, she and her co-authors observed the behavior of ten rig sharks housed in tanks equipped with underwater microphones. They discovered that all ten sharks begin to create click noise when they move between tanks or are held gently.

On average, the shark clicks nine times at 20-second intervals, and researchers believe they made noises by stitching the teeth together.

They didn’t make any noise while feeding or swimming, making scientists believe it is more likely to click when emphasizing or surprised, not as a way of communicating with each other.

“I think it’s likely that they’ll make those noises when they’re attacked,” Dr. Nieder said, adding that many other fish will snap their teeth and jaws to stop or distract predators.

It was unclear whether the shark could hear the clicks themselves. Did they make the sound in the wild or just get caught? And whether they intentionally made it or whether it was a side effect of their reaction to being surprised, Dr. Nieder said.

Christine Elbe, director of the Marine Science and Technology Centre at Curtin University in Australia, said the study expanded in the growing field of research into how marine animals make and hear sounds.

“Once you start watching, there are more and more species that use sounds,” she said.

So it wasn’t surprising to find that sharks could make a fuss, she said.

But she says, “I think it’s important in the sense that it completely underestimates communication between animals and environmental sensing capabilities, and also completely underestimates the way noise affects it.”

Reduced number of flights may decrease prediction accuracy

The National Weather Service has been releasing weather observations at over 100 sites across the country for decades, operating like clockwork in the Pacific and Caribbean.

Meteorologists launch balloons equipped with radiozond devices twice a day at 8am and 8pm ET. These balloons rise about 15 feet every 2 hours, collecting data on temperature, humidity, and wind speed as they ascend through the atmosphere. The data is transmitted back using radio waves.

When the balloons reach a certain altitude, they pop and descend back to Earth with parachutes, completing their mission. The data gathered from these balloons is crucial for feeding into weather models that form the basis of forecasts in the United States.

However, many of the launch sites have been impacted by staffing cuts under the Trump administration, leading to reduced launches and restrictions. Meteorologists and experts are concerned that these changes will compromise forecast quality and increase risks during severe weather events.

The cuts in balloon launches are part of a broader downsizing effort across federal agencies. The National Oceanic and Atmospheric Administration, which includes the National Weather Service, has seen significant staff reductions and budget cuts.

Recent announcements about balloon launch suspensions in various locations across the country have raised concerns among meteorologists. These cuts could have implications for weather forecasting accuracy, particularly in regions prone to severe weather events.

Weather balloons play a critical role in providing high-resolution data on atmospheric conditions, which is essential for accurate weather modeling. Without this data, forecasters may struggle to predict events like storms and precipitation types.

Private companies are attempting to fill the gaps left by the National Weather Service cuts, but it is unlikely they will fully replace the services provided by NOAA. These companies are looking to expand coverage and enhance existing data collection efforts.

The impact of these cuts on weather forecasting remains to be seen, but there is concern among experts that forecast accuracy could suffer without the crucial data collected by weather balloons.

Trump to Ease Tariffs on China in Exchange for TikTok Deal

Donald Trump has expressed his willingness to reduce tariffs on Chinese trade in exchange for the sale of Tiktok, a social media app used by 170 million Americans, by its Chinese parent company.

He acknowledged China’s involvement in any agreement, stating, “China will have to play a role in it, perhaps giving approval, I believe they will.” Trump mentioned the possibility of offering China a concession to facilitate the deal.

Trump’s remarks indicate that the sale of Tiktok is a priority for his administration and that tariffs are being used as a negotiation tool with Beijing.

Tiktok did not provide an immediate response to the situation.

Bytedance, the parent company of Tiktok, faces an April 5 deadline to find non-Chinese buyers for the app or risk a US ban on national security grounds that was established in January under the 2024 law.

Washington’s concerns about Chinese ownership of Tiktok have led to the current situation, with fears that Beijing could exploit the app for malicious purposes and gather data on Americans.

Recently, Trump imposed an additional 20% tariff on all imports from China, demonstrating his administration’s firm stance on trade negotiations.

Securing a deal without Chinese control has been a key focus in finalizing the Tiktok transaction, with tariffs used as leverage in negotiations with Beijing.

In his earlier statements, Trump had warned China that failure to approve US deals with Tiktok could result in further tariffs being imposed.

Vice President JD Vance anticipates that the terms of the agreement regarding Tiktok ownership will be settled by April 5th.

Reports indicate that a White House-led meeting between investors is working towards securing US business interests for video apps, involving major Chinese stakeholders.

The fate of Tiktok, a widely-used app in the US, has been uncertain since the bipartisan decision to sell it by January 19th.

After initial turbulence in January, the app was temporarily banned but resumed operations shortly after Trump’s term began. He subsequently extended the deadline for the sale until April 5th and hinted at the possibility of further extensions.

The intense involvement of the White House in these trade discussions is unprecedented, resembling the role of an investment bank.

Critics argue that the ban on Tiktok infringes on Americans’ freedom of speech by restricting access to foreign media, potentially violating the First Amendment of the US Constitution.

Gaia ceases operations after completing decade-long mapping of the Milky Way

From ancient creeks of stars to the innards of white dwarfs, the Gaia Space Telescope has seen it all.

On Thursday, the European Space Agency’s mission specialists will send the low-fuel Gaia into orbit around the Sun, turning it off to astronomers around the world after more than a decade of service.

Gaia has been charting the universe since 2014, creating a vast encyclopedia of the position and movement of celestial objects from the Milky Way and beyond. It is difficult to grasp the breadth of development and discovery that a spinning observatory is enabled. But here are a few numbers: nearly 2 billion stars, millions of potential galaxies, and around 150,000 asteroids. These observations were brought Over 13,000 studies so far by astronomers.

Gaia changed the way scientists understand the universe, and that data became the reference point for many other telescopes on the ground and in the universe. Additionally, less than a third of the data collected has been released to scientists so far.

“It now supports almost everything in astronomy,” says Anthony Brown, an astronomer at Leiden University in the Netherlands, heading Gaia’s data processing and analysis group. “If you were to ask my astronomy colleagues, I don’t think they could have imagined that Gaia would have to do her research even if she wasn’t there.”

Starting in 2013, Gaia’s main goal was to uncover the history and structure of the Milky Way by constructing the most accurate, three-dimensional map of the position and velocity of 1 billion stars. As there is only a small portion of that data, astronomers Halo mass of dark matter We swallowed and identified our galaxy Thousands of trespassing stars ingested from another galaxy 10 billion years ago.

Dr. Brown measures continuous vibrations on the Milky Way disk and measures a kind of galactic seismology – evidence Of encounters with satellite galaxies that have put ourselves in orbit much more recently than scientists believed. That may be the reason for the Milky Way It looks distorted When viewed from the side.

Experts predict significant decline in bee populations by 2025

Entomologists at Washington State University predict that the US Honeybee colony may decline by up to 70% by 2025.

The university revealed in a News Release that over the last decade, annual losses of Honeybee Colonies averaged between 40% and 50%. However, this year, a combination of factors such as nutritional deficiencies, mites infections, viral diseases, and potential pesticide exposure during the previous pollination season contributed to even higher losses.

Priya Chakrabarti Basu, assistant professor of health and pollinator behavior at WSU, expressed concern over the increasing losses, stating, “The demand for pollination remains high, putting pressure on beekeepers to maintain colonies to meet these needs.”

The implications could be significant as about 35% of the world’s food depends on pollinators, as stated by the National Institute of Food and Agriculture.

Brandon Hopkins, professor of pollinator ecology at WSU, warned that higher colony losses could result in increased costs for farmers relying on bee colonies.

Hopkins added, “This level of national loss could potentially lead to beekeepers facing bankruptcy, affecting farmers who depended on them for pollination.”

The Honeybee industry had a production value of around $350 million in 2023, as reported by the Agriculture Department.

Hopkins noted that extreme Honeybee losses also pose a particular risk to the almond industry this year.

He stated, “The almond industry heavily relies on robust colonies, and this year, due to low supply, any beehives are in high demand.”

Reflecting on the situation, Hopkins added, “I haven’t seen a decline like this since the colony collapse in 2008.”

Latamgpt’s goal is to develop AI that accurately reflects the diverse culture of Latin America

Latin America has been a source of inspiration for various aspects, including a popular literary and musical genre and staple foods like potatoes. A famous Happy meal is now an indication of this inspiration. There is potential for Latin America to also become a cradle for AI.

A coalition of research institutes is collaborating on a project called latamgpt, which aims to create a tool that considers regional language differences, cultural experiences, and “specificity.” This tool is intended to provide more accurate representations for users in Latin America and the Caribbean compared to existing Large Language Models (LLM) primarily trained by US or Chinese companies in English.

The project lead, Rodrigo Duran Rojas, expressed the importance of developing local AI solutions to better serve Latin America. The goal is to offer a representative outlook tailored for the region, with initial tests showing promising results in areas like South American history.

Over 30 institutions are involved in the development of Latamgpt from countries across the hemisphere, including collaborations with Latinos in the US like Freddy Vilci Meneseth, an associate professor of Hispanic Studies at Lewis & Clark College, Oregon.

Latamgpt’s launch is planned for around June, following a significant commitment from various regions for improved AI governance. Projects like monitoring deforestation in the Amazon Rainforest and preserving historical documents from past dictatorships are contributing to the dataset used for training Latamgpt.

With a dataset of over 8 terabytes, Latamgpt aims to provide a nuanced and localized model for various applications. The project faces challenges in incorporating diverse dialects and complex grammatical structures, but emphasizes the importance of collaboration for continued development.

Diversified dialects and complex grammar challenges

Efforts like Latamgpt, CHATGPT, and Google’s Gemini are working towards incorporating a wider range of data and improving localization for non-English languages. Challenges in training models for languages with complex grammar and dialects persist.

Despite these challenges, Latamgpt aims to address these issues through collaboration with institutions, libraries, and archives across the region. The project continues to receive data and feedback to enhance its capabilities and explore applications in public policy and regulation.

The long-term goal of Latamgpt is to create an interconnected network for developing AI solutions with a Latinx touch, emphasizing the impact of collaboration in shaping the future of technology in Latin America and beyond.

Chinese researchers announce successful liver transplants from pigs into brain dead patients

Chinese researchers have made progress in the field of inter-animal organ transplantation with a successful pig kidney transplant reported on Wednesday. They believe that pig liver may also prove to be useful in the future.

This Chinese patient is the third person worldwide known to be living with gene-edited pig kidneys. The research team has also successfully experimented with implanting pig liver into brain-dead individuals.

Scientists are genetically modifying pigs to make their organs more human-like in the hopes of addressing the shortage of organ transplants. While previous xenografts in the US were short-lived, two recipients of pig kidneys – an Alabama woman in November and a New Hampshire man in January – have shown promising results. Clinical trials in the US are now commencing.

Nearly three weeks after the kidney transplant, the Chinese patient is reported to be doing “very well” with the pig kidneys functioning effectively, according to Dr. Lin Wang of Xijing Hospital. The patient is a 69-year-old woman who has been suffering from kidney failure for eight years.

The next challenge for xenotransplantation is learning to transplant pig livers. In an experiment reported on Wednesday, pig liver was successfully transplanted into a brain-dead individual for 10 days. While the pig liver produced bile and albumin, essential for basic organ function, it did not perform as well as a human liver.

Dr. Wang believes that the pig liver could potentially support a failing human liver to some extent. In the US, a similar approach is being studied by pig developer Egenesis, where a pig’s liver is externally attached to support a brain-dead individual’s liver function.

In China, the team led by Dr. Wang did not remove the deceased person’s own liver but instead implanted the pig liver nearby.

Dr. Parsia Vagefi, a liver transplant surgeon, commented on the experiment, stating that while it shows promise, there are still many questions that need answers. Dr. Wang’s team plans to analyze the results of another brain-dead individual who received a pig liver transplant.

Last year, another Chinese hospital reportedly transplanted a pig liver into a living patient after removing part of their cancerous liver, but the outcome of the experiment is unclear.

The Role of AI Chatbots in ChatGPT and DeepSeek Technology

In September, Openai announced a new version of ChatGPT, designed to infer through tasks that include mathematics, science, and computer programming. Unlike previous versions of chatbots, this new technology allows you to spend time “thinking” through complex problems before you settle for an answer.

Soon, the company said the new inference technology outperformed the industry’s leading systems in a series of tests tracking advances in artificial intelligence.

Currently, other companies such as Google, Anthropic, and China’s Deepseek offer similar technologies.

But can AI actually reason like a human? What does computers mean? Are these systems really close to true intelligence?

This is the guide.

Inference means that chatbots spend more time tackling the problem.

“We’re committed to providing a new technology to our AI startup,” said Dan Klein, professor of computer science at the University of California, Berkeley and chief technology officer at Scaled Cognition, an AI startup.

You could try to split the problem into individual steps or try to solve it via trial and error.

The original ChatGpt answered the question immediately. A new inference system can resolve problems in seconds or minutes before answering.

In some cases, the inference system will improve its approach to the question and repeatedly attempt to improve the selected method. Otherwise, you may try several different ways to approach the problem before you settle on one of the problems. Or maybe it’s back and check out some work that I did a few seconds ago to see if it’s correct.

Essentially, the system will try to do everything possible to answer your questions.

This is like an elementary school student struggling to find a way to solve a math problem, scribbling several different options on paper.

It can potentially infer about something. However, when asking questions that involve mathematics, science, and computer programming, reasoning is most effective.

You can ask previous chatbots and check your work to show how they reached a specific answer. The original ChatGpt also allows for this kind of self-reflection as they learned from texts on the internet, showing how people reached their work and how they checked their work.

However, the reasoning system is moving further. You can do these kinds of things without being asked. And you can do them in a broader and more complicated way.

Companies call it the inference system. Because it feels like it behaves like someone who is thinking about difficult problems.

Companies like Openai believe this is the best way to improve chatbots.

For years, these companies relied on simple concepts. The more internet data you pump to your chatbot, the better these systems were running.

But in 2024, they ran out of almost all of the texts on the internet.

That is, we needed a new way to improve chatbots. So they began building an inference system.

Last year, companies like Openai began to lean heavily towards a technology known as Rencemone Learning.

While this process can be extended over several months, AI systems can learn to do things through extensive trial and error. For example, by solving thousands of mathematics problems, you can learn which methods lead to the correct answer and which ones not.

Researchers have designed a complex feedback mechanism that shows the system when it does the right thing and when it does something wrong.

“It’s a bit like training a dog,” said Jerry Tworek, a researcher at Openai. “If the system works out, we give you cookies. If that doesn’t work, we say ‘bad dogs.’ “

(New York Times sued Openai and its partner Microsoft in December for copyright infringement of news content related to AI systems.)

It works very well in certain fields, such as mathematics, science, computer programming. These are areas where companies can clearly define good and bad behavior. There is a definitive answer to mathematics problems.

Reinforcement learning also does not work well in areas such as creative writing, philosophy, and ethics. Researchers say that this process can generally improve the performance of AI systems, even if it answers questions outside of mathematics and science.

“It gradually learns the patterns of reasoning that leads it in the right direction, and learns which isn’t,” said Jared Kaplan, chief science officer of humanity.

no. Reinforcement learning is the method companies use to build inference systems. Finally, the chatbot can infer is during the training phase.

absolutely. Everything a chatbot does is based on probability. It chooses the path that most resembles the data it learns, whether it comes from the Internet or is generated through reinforcement learning. Sometimes I choose an option that’s wrong or makes no sense.

AI experts are split on this question. These methods are still relatively new, and researchers are still trying to understand their limitations. In the AI field, new methods often progress very quickly at first.

The Era of Ozempic is Just Starting.

u grabowsky/imagebroker/shutterstock

Just a year ago, hype was being built around semaglutide drug Ozempic and Wegovy, so the conversation revolved around the possibility of “end obesity” by helping people lose a lot of weight.

Then there was talk about how the appeal for semaglutide weight loss caused a shortage in people who needed it to treat diabetes, and which celebrities got it. Despite the topic, these treatments were still somewhat exotic.

There is no more talk of shortages today. In fact, it’s easier than ever to get these medications from an online pharmacy if you have the funds and a proper BMI. At the speed of lightning, the jab has become a common name. You or someone you know may be taking it often.

Some data show that one in eight people in the US tried one of the new generation of weight loss pills. In the UK, they have taken about 1 in 7 people or have family and friends. It’s fair to say we live in the Ozempic era, and it changes much more than our collective waistline.

Many people experiment with small amounts of weight loss medication, is this a good idea?

This special report clearly looks at the new normality and the questions it raises. These treatments refer to traditional approaches to weight loss, particularly exercise (see Why exercise is more important than ever when taking weight loss medications). Drugs people see “GLP-1 drugs are the beginning – the next powerful drug is expected”)? Over the past year, studies have been found that examined the benefits of other conditions, including Alzheimer’s disease, depression, and addiction. So how do they affect the brain beyond appetite regulations (see “Do GLP-1 drugs really tell us about the brain’s reward system?”)?

Many people are experimenting with taking them at lower doses, which is a good idea (“I’m getting an increase in microdeficient GLP-1 drugs, does that work?”)? We also ask what all of this means for society as a whole (see “Unexpected Effects of Society Transformed by Weight Loss Drugs”) and what comes next (see “GLP-1 Drugs Is the Beginning – The Powerful Drugs You Expect Next”).

What’s clear is that the new boom in weight loss pills is just the beginning. In another year, things can look very different again.

The Revealed Long-Term Effects of Pregnancy on Different Body Parts

SEI 245216256

Pregnancy has many effects on the body

Anna Still/Getty Image

As anyone who goes through it knows, pregnancy transforms the body a lot. And now we have the most detailed picture of how it affects the blood, organs and immune system each week. This not only helps to provide post-pregnancy treatment, but also helps to identify the risk of developing certain conditions during pregnancy.

“We’ve got an unprecedented view of how much it takes a mother’s body to change weekly, to make up for the incredible load and how long it takes to recover after delivery,” he says. Uriaron At the Wiseman Institute of Science, Rehobot, Israel.

Despite its importance, pregnancy has not been studied, Aron says. For example, previous studies have tracked how about 20 blood markers change, including salt and iron levels. Up to about 6 weeks for dozens of pregnant women After delivery, samples collected during standard healthcare will be used. “These experiments are usually performed in a small number of patients and sample only once at the late pregnancy or at each time point,” Aron says.

To gain a more comprehensive view, Aron and his colleagues analyzed previously collected blood samples from over 160,000 women in Israel, ages 25 to 31. Together, these samples provided weekly, weekly physical snapshots from 20 weeks of conception to 18 months after birth, with each woman providing several points of data. This approach gives useful insight into how the body generally changes during pregnancy at the population level, but says that following the same woman over time will provide a better picture of the individual trajectory. Christofree Imperial College London.

The researchers mapped changes in 76 blood markers, including levels of protein, fat and salt that show the functioning of the liver, kidneys, blood, muscle, bone and immune system. They found that each of these markers differed significantly from preconcept levels during pregnancy to gradually return to preconceived levels or reverse overshooting before returning to preconceived baseline.

In particular, scientists found that 36 markers, including those associated with blood clotting, bounced off within a month of delivery, but 31 markers took more than 10 weeks to recover. For example, some changes to the liver and immune system took about 5 months to return to prepregnancy levels, and some kidney markers took about six months. Some bone and muscle markers took even longer. It is unclear what exactly this means for women’s health, but it should be investigated in future work, Aron says.

Additionally, several other markers did not return to baseline levels for more than one year after birth. “The slightly archaic view that by six or eight weeks after pregnancy, everyone is completely back to normal is clearly wrong,” says Leeds.

For example, iron levels remained much lower after giving birth. “Women are very likely to have anemia [have low iron levels] I think it will take 6-12 months for the iron shop to return to normal after giving birth due to bleeding, and as the developing fetus removes many iron stores from the body.

Meanwhile, levels of proteins called CRP remained high. “CRP is affected by many different processes. Inflammation is certainly one of them, but things like hormonal changes can also affect this,” says Lees. In another analysis, the team examined differences in markers between women with prelammosis. This saw people who are pregnant and not with hypertension, where high blood pressure can cause headaches, vision problems and pain under the ribs. This revealed that women who developed pre-lamp syndrome before conception had increased levels of blood cell fragments called platelets and proteins called ALT.

“For decades, the idea was that if the placenta wasn’t properly planted and not properly planted, the blood supply would be destroyed and the mother would release the hormones and substances that would help her blood pressure,” says Leeds. “However, some studies suggest that those who developed it have different cardiovascular functions before pregnancy. These findings add weight to this theory.”

If further studies have shown that these conceptual markers actually indicate the risk of pre-lammosis, they could be used to identify potentially high-risk women. “Then you can target ways to improve your health before pregnancy (through exercise and lifestyle advice) and reduce your risk,” says Leeds.

The Increased Importance of Exercise with Weight Loss Medication

For decades, traditional wisdom has believed that in order to lose weight, you have to eat less and move more. Of course, that’s easier said than done. That’s why drugs like Wegovy are so innovative. By suppressing appetite, they help to tackle the first part of the equation, which usually leads to dramatic weight loss. But what about the second one? If weight loss pills are reducing the number of scales, should we still head to the gym? And how do these drugs affect our athletic ability?

What has become clear is that it may be even more important for those taking these medications than those who don’t. The ability of semaglutide to induce rapid weight loss (see “How do they work?” below) also leads to a significant decrease in muscle mass. For example, a 2021 study of 95 people who were overweight or obese taking semaglutide found that their lean body mass was reduced by almost 10% on average, 68 weeks later.

This article is part of a special series investigating the GLP-1 agonist boom. Click here for details.

Lean body weight covers body tissues such as muscles and bones. Therefore, these results suggest that both are affected when taking weight loss medications, Signee Sørensen Torekov at the University of Copenhagen explains. These drugs guide people to burn fewer calories, so the body needs to break down fat, muscle, and even bones for nutrients.

“Our understanding is that up to about 40% of the overall weight loss seen in semaglutide is thought to be due to the loss of muscle mass,” he said.

Renowned Mathematician Masaki Kashiwara Awarded the 2025 Abel Prize for Breakthrough Equation-solving Tool

Kashiwara’s work is very abstract, but is seen as important

Peter Bagde / Typos1 / The Abel Prize

Red-tailed For his research on algebraic analysis, he received the 2025 Abel Prize, known as the Nobel Prize in Mathematics.

Professor of Kashiwara Kyoto UniversityJapan received the award “for his fundamental contributions to algebraic analysis and representational theory, particularly for the development of the theory of D-modules and the discovery of crystal bases.”

His work involves the use of algebra, focusing on investigating geometry and symmetry, and using those ideas to find solutions to differential equations that include the relationship between mathematical functions and their rate of change. Finding solutions to such equations can be particularly difficult, especially for functions with several variables, and therefore with several rates of change. These are known as partial differential equations (PDEs).

Kashiwara’s important work on the D-module, a highly specific area of ​​algebraic analysis, including Linear PDE, was conducted surprisingly early in his career during his doctoral dissertation. He has worked with over 70 collaborators. Kashiwara said New Scientist He was pleased to win the Abel Prize, but he is still active and would like to make further contributions.

“I’m currently working on representative theory of quantum affine algebra and its related topics,” he says. “There’s a great guess: [the] “Affine epicenter speculation,” but I still don’t know how to solve it. ”

David Craven At the University of Birmingham, UK, Kashiwara’s work is very abstract and far from a direct real-world application, and even basic summary says that a minimum of a doctorate in mathematics is required. “That’s the level of these things being difficult,” he says. “It’s incredibly esoteric.”

However, Craven says that Kashiwara had a major impact on his field. “What he did is permeate theories of expression. If you want to do geometrical expression theory, you can’t escape from Kashiwara.

Gwyn Bellamy “All the big results on the field are [algebraic analysis] It was more or less due to him, and Kashiwara’s Abel Prize victory has been a long time.

Named after Norwegian mathematician Neils Henrik Abel, the Abel Prize is awarded annually by the King of Norway. Last year, Michelle Taragland won for his work in extreme studies of probability theory and randomness.

Rare bipolar dinosaurs uncovered in Mongolia by scientists

A new species of dinosaurs has been uncovered in the Gobi Desert, Mongolia. Known as Duonychus tsogtbaatari, this dinosaur possessed two feet long claw fingers on each hand, belonging to the Teresino Sauria.

Referred to as Duonychus, which is the Greek term for two claws, this dinosaur stood approximately 10 feet tall, weighed around 570 pounds, and was part of the Therizinosaurs group. It displayed a unique set of characteristics, including feathers.

These dinosaurs existed in Asia and North America during the Cretaceous period, spanning from 145 to 66 million years ago.

Despite having only two claws, researchers described Duonychus in a study published in the JournalIscience as an “effective climber” capable of reaching branches or vegetation masses up to five inches in diameter.

NBC News reached out to the research team for additional comments.

The fossil specimen was unearthed in 2012 by scientists at the Institute of Paleontology at the Mongolian Academy of Sciences, dating back 90 million years and showcasing exceptional diversity.

Although the fossil was a partial skeleton missing the skull and legs, the hands were remarkably well-preserved. The Duonychus individuals were not fully grown, and their claws measured approximately 1 foot in length.

Therodinosaurus belonged to a group of herbivorous dinosaurs such as tyrannosaurus and spinosaurus, but mainly consumed leaves from large shrubs and trees.

The discovery of Duonychus and its two claws was described as remarkable by Michael Benton, a vertebrate paleontology professor at the University of Bristol, UK, who was not involved in the study.

Initially, dinosaurs possessed five fingers like humans, eventually losing two over time, leading to the majority having three fingers, Benton explained in an email to NBC News on Wednesday.

Benton highlighted that the number of digits did not impact their capabilities, mentioning that the third finger was shorter in length, potentially serving a specific purpose.

He emphasized the vast diversity and varied shapes and functions of dinosaurs, stating that they are incredibly diverse.

According to the study, the fossil records of Terazinosauria are particularly abundant in Cretaceous sediments in East Asia, particularly in Mongolia and China.

United Nations Education, Science and Cultural Organizations (UNESCO) recognizes the Gobi Desert in Mongolia as the largest dinosaur fossil repository in the world.
