As the engineers who build self-driving cars know, it can be hard to get an AI system to reliably make sense of what it sees. Most systems designed to "understand" videos in order to either classify their content ("a person playing tennis," for example) or identify the contours of an object--say, a car up ahead--work in what's called "pixel space." The model essentially treats every pixel in a video as equal in importance. But these pixel-space models come with limitations. Imagine trying to make sense of a suburban street. If the scene has cars, traffic lights and trees, the model might focus too much on irrelevant details such as the motion of the leaves. It might miss the color of the traffic light, or the positions of nearby cars. "When you go to images or video, you don't want to work in [pixel] space because there are too many details you don't want to model," said Randall Balestriero, a computer scientist at Brown University. Yann LeCun, a computer scientist at New York University and the director of AI research at Meta, created JEPA, a predecessor to V-JEPA that works on still images, in 2022.

Judge puts a one-year limit on Google's contracts for default search placement It comes after the September ruling that Google will not have to sell off Chrome, but must make changes. A federal judge has expanded on the remedies decided for the Department of Justice's antitrust case against Google, ruling in favor of putting a one-year limit on the contracts that make Google's search and AI services the default on devices, reports. Judge Amit Mehta's ruling on Friday means Google will have to renegotiate these contacts every year, which would create a fairer playing field for its competitors. The new details come after Mehta ruled in September that Google would not have to sell off Chrome, as the DOJ proposed at the end of 2024. This all follows the ruling last fall that Google illegally maintained an internet search monopoly through actions including paying companies such as Apple to make its search engine the default on their devices and making exclusive deals around the distribution of services such as Search, Chrome and Gemini.

Waymo's robotaxi fleet is being recalled again, this time for failing to stop for school buses This voluntary recall follows a federal investigation that claimed the robotaxis illegally passed stopped school buses. To prevent its robotaxi fleet from passing stopped school buses, Waymo is issuing another software recall in 2025. While it's not a traditional recall that pulls vehicles from the road, Waymo is voluntarily updating software for its autonomous fleet in response to an investigation from the National Highway Traffic Safety Administration. According to Waymo, the recall will be filed with the federal agency early next week. Mauricio Peña, Waymo's chief safety officer, said in a statement that Waymo sees far fewer crashes involving pedestrians than human drivers, but that the company knows when our behavior should be better.

A drone attack on the town of Kalogi, in Sudan's South Kordofan region, is said to have hit a kindergarten and killed at least 50 people, including 33 children. The Rapid Support Forces (RSF), the paramilitary group battling the army in Sudan's civil war, was accused of Thursday's attack by a medical organisation, the Sudan Doctors' Network, and the army. There was no immediate comment from the RSF. The RSF in turn accused the army of hitting a market on Friday in a drone attack in the Darfur region, on a fuel depot at the Adre border crossing with Chad. Sudan has been ravaged by war since April 2023 when a power struggle broke out between the RSF and the army, who were formerly allies .

An international study of over 1,400 adults found that creative activities like music, dance and visual art help keep brains biologically younger than chronological age.

'Individually, these photographs speak to beauty, fragility, and wonder.' A sperm whale floats amid shards of polar pack ice, dead and decomposing, mouth hanging open. When photographer Roie Galitz captured the scene with a drone, the image was so arresting that it took a moment to notice the hungry female polar bear stretching her jaw to break through the whale's leathery skin. Galitz was leading a photography expedition along Norway's Svalbard archipelago when he spotted a blackened blob floating on the horizon. As the icebreaker drew close, he could see (and smell) that the blob was a massive decaying carcass releasing an occasional exhalation of noxious gas, like a big air cushion.

Artificial intelligence research has a slop problem, academics say: 'It's a mess' AI research in question as author claims to have written over 100 papers on AI that one expert calls a'disaster' A single person claims to have authored 113 academic papers on artificial intelligence this year, 89 of which will be presented this week at one of the world's leading conference on AI and machine learning, which has raised questions among computer scientists about the state of AI research. Zhu himself graduated from high school in 2018. Papers he has put out in the past two years cover subjects like using AI to locate nomadic pastoralists in sub-Saharan Africa, to evaluate skin lesions, and to translate Indonesian dialects.

Environment Animals Wildlife Endangered Species German hairy snails are disappearing from London's River Thames Londoners are scouring riverbanks to save the endangered mollusk. Breakthroughs, discoveries, and DIY tips sent every weekday. Researchers believe that its signature hairs help the strange creature live in its damp, riverside environments by enabling it to sweat off moisture. By wicking off that excess moisture, the slime gets more sticky, so the snail can hold onto the slick riverside debris and the plants it eats. However, the snail needs some extra support.

This premium gaming handheld loads up with features for power users, but Windows still holds it back from being the easy option. Performance is better than previous-generation handhelds. Detachable controllers are comfortable and improve usability. Windows on a handheld is still frustrating. Many companies have tried and failed to produce gaming handhelds that run Windows, and it's not hard to see the appeal.

Inside cowboy Charles Jesse "Buffalo" Jones's get-rich-quick scheme to restore the plains 100 years ago. By 1888, Charles Jesse "Buffalo" Jones had succeeded in crossbreeding a buffalo with cow, a hybrid he claimed would be as tasty as beef and as hardy as buffalo. Breakthroughs, discoveries, and DIY tips sent every weekday. The "cattalo" was a homely creature--stocky and shaggy, with a slight buffalo's hump and a cow's docile face. Charles "Buffalo" Jones invented the cow-buffalo hybrid in 1888.
