This was the year that A.I.-generated content passed a kind of audiovisual Turing test, sometimes fooling us against our better judgment. The Turing test, a long-established tool for measuring machine intelligence, gauges the point at which a text-generating machine can fool a human into thinking it's not a robot. ChatGPT passed that benchmark earlier this year, inaugurating a new technological era, though not necessarily one of superhuman intelligence . More recently, however, artificial intelligence passed another threshold, a kind of Turing test for the eye: the images and videos that A.I. can produce are now sometimes indistinguishable from real ones. As new, image-friendly models were trained, refined, and released by companies including OpenAI, Meta, and Google, the online public gained the ability to instantly generate realistic A.I. content on any theme they could imagine, from superhero fan art and cute animals to scenes of violence and war.

Is Cognitive Dissonance Actually a Thing? In 1934, an 8.0-magnitude earthquake hit eastern India, killing thousands and devastating several cities. Curiously, in areas that were spared the worst destruction, stories soon spread that an even bigger disaster was on its way. Leon Festinger, a young American psychologist at the University of Minnesota, read about these rumors in the early nineteen-fifties and was puzzled. Festinger didn't think people would voluntarily adopt anxiety-inducing ideas. Instead, he reasoned, the rumors could better be described as "anxiety justifying." Some had felt the earth shake and were overwhelmed with fear. When the outcome--they were spared--didn't match their emotions, they embraced predictions that affirmed their fright.

Drone attacks kill over 100 civilians across war-torn Sudan's Kordofan At least 104 civilians have been killed in drone attacks across Sudan's Kordofan region as fighting between rival military factions reached deadly new heights in the brutal civil war deep into its third year. The attacks have battered the central region since early December, right up to Friday, following the capture of a significant army base by the paramilitary Rapid Support Forces (RSF) in Babnusa after a week of intense fighting. Sudan's RSF trying to hide atrocities: Report The deadliest attack was reported from a kindergarten and a hospital in Kalogi, South Kordofan, where 89 people were killed, including 43 children and eight women. United Nations human rights chief Volker Turk said he was "alarmed by the further intensification in hostilities" and warned that targeting medical facilities violates international humanitarian law. Six Bangladeshi peacekeepers serving with the UN mission were killed when drones hit their base in Kadugli, South Kordofan's capital, on December 13.

This is Europe's secret weapon against Trump: it could burst his AI bubble T he unthinkable has happened. The US is Europe's adversary. The stark, profound betrayal contained in the Trump administration's national security strategy should stop any further denial and dithering in Europe's capitals.

The judge recommends suspending Tesla's sales in the state for 30 days. Tesla, Inc. is an American automotive and clean energy company. Tesla's sales in California should be suspended for 30 days because its marketing around Autopilot and Full Self-Driving misled consumers, a California administrative law judge has ruled . Back in 2022, the California DMV accused the automaker of using deceptive language to advertise those products and making it seem like its vehicles are capable of level 5 autonomous driving. Tesla has since added the word "Supervised" to the name of its Full Self-Driving assistance technology.

What is in the 28-point US plan for Ukraine? 'Ukraine is running out of men, money and time' Can the US get all sides to end the war? Why is Europe opposing Trump's peace plan? Kyiv Mayor Vitalii Klitschko said explosions were heard in the Ukrainian capital and warned people to stay in shelters late on Tuesday night as air defences worked to repel a Russian attack. Russian forces launched a "massive" drone attack on Ukraine's Sumy region, targeting energy infrastructure and causing electricity blackouts, Governor Oleh Hryhorov said on Telegram late on Tuesday night.

AI-assisted hiring will drive Indeed's growth, Recruit CEO says Companies embracing artificial intelligence to recruit and hire people won't threaten Indeed.com's Hisayuki "Deko" Idekoba, who leads Indeed and its parent, Tokyo-based Recruit Holdings, said the business is using AI to help companies optimize their talent-acquisition approach based on the pool of candidates, number of applicants per job and other factors, while using the flow of data to set compensation levels or adjust job qualifications. "We're gradually starting to deploy solutions such as AI agents to customers," Idekoba said in an interview in Tokyo. For Recruit, the shift reflects a broader transformation in how employers find and evaluate talent, as AI reshapes recruitment worldwide. Automated tools are speeding up candidate screening, cutting hiring costs and helping businesses respond to labor shortages and changing skill demands.

A 20,000 year old fossil uncovered in a tarantula-filled cave has paleontologists stunned. Breakthroughs, discoveries, and DIY tips sent every weekday. Bees are frequently associated with large queen-serving colonies featuring hundreds if not thousands of insects . They lay their eggs in small cavities, and they leave pollen for the larvae to eat," explained paleontologist Lazasro Viñola López . "Some bee species burrow holes in wood or in the ground, or use empty structures for nests." Viñola López, a researcher at Chicago's Field Museum, added that some European and African species even construct nests inside vacant snail shells. That said, a beehive inside a bone is a new one even for seasoned researchers. Estimated to be around 20,000 years old, this newly discovered specimen is also the first known example of such a home, past or present. The findings are detailed in a study published on December 16 in the journal . Researchers located the unique find while exploring the many limestone caves that dot the southern Dominican Republic. Sinkholes are common across the Caribbean island of Hispaniola, and are often so well sheltered from the elements that they function like underground time capsules. These windows into the past are largely thanks to the work of the island's owls . The predatory birds often make their nests inside these caves, where they regularly cough up owl pellets filled with the undigested bones of their prey. Over thousands of years, these layers of bones fossilize atop one another across carbonate layers created from rainy periods. "The initial descent into the cave isn't too deep-we would tie a rope to the side and then rappel down," Viñola López said. "If you go in at night, you see the eyes of the tarantulas that live inside." After proceeding past the large spiders through about 33 feet of underground tunnel, the paleontologists began finding various fossils. Many belonged to rodents, but there were also bones from birds, reptiles, and even sloths for a total of over 50 different animal species. "We think that this was a cave where owls lived for many generations, maybe for hundreds or thousands of years," said Viñola López. "The owls would go out and hunt, and then come back to the cave and throw up pellets.

A BBC investigation has uncovered claims that essay cheating remains widespread at UK universities despite the introduction of a law designed to stop it. Since April 2022, it has been illegal to provide essays for students in post-16 education in England. But so far there have been no prosecutions. The BBC has spoken to a former lecturer who describes essay cheating as an open secret and to a businessman who claims to have made millions from selling model answer essays to university students. Universities UK, which represents 141 institutions, said there were severe penalties for students caught submitting work that was not their own.

Stochastic optimization is fundamental to modern machine learning. Recent research has extended the study of stochastic first-order methods (SFOMs) from light-tailed to heavy-tailed noise, which frequently arises in practice, with clipping emerging as a key technique for controlling heavy-tailed gradients. Extensive theoretical advances have further shown that the oracle complexity of SFOMs depends on the tail index $α$ of the noise. Nonetheless, existing complexity results often cover only the case $α\in (1,2]$, that is, the regime where the noise has a finite mean, while the complexity bounds tend to infinity as $α$ approaches $1$. This paper tackles the general case of noise with tail index $α\in(0,2]$, covering regimes ranging from noise with bounded variance to noise with an infinite mean, where the latter case has been scarcely studied. Through a novel analysis of the bias-variance trade-off in gradient clipping, we show that when a symmetry measure of the noise tail is controlled, clipped SFOMs achieve improved complexity guarantees in the presence of heavy-tailed noise for any tail index $α\in (0,2]$. Our analysis of the bias-variance trade-off not only yields new unified complexity guarantees for clipped SFOMs across this full range of tail indices, but is also straightforward to apply and can be combined with classical analyses under light-tailed noise to establish oracle complexity guarantees under heavy-tailed noise. Finally, numerical experiments validate our theoretical findings.
