Flying across several time zones often causes jet lag, a feeling when the body insists it's the middle of the night while the clock says it's lunchtime. Now it turns out this nuisance is not exclusive to humans. A new Science study on Manx shearwaters, seabirds that can fly hundreds of kilometers a day over the North Atlantic, shows they jet-lag themselves during their excursions. And because the

In May 2021, the US Food and Drug Administration released a lengthy briefing document on an experimental medication for a rare autoimmune form of vasculitis that often damages the kidneys and lungs. The agency was on the fence about whether to approve the treatment, and it wanted an independent advisory committee to weigh in. Among the questions at hand: Was the drug meaningfully better than exis

The Hubble Space Telescope still shines in the eyes of astronomers after 36 years in orbit, but it is not as nimble as it once was. Left alone, the observatory will plunge back into the atmosphere in the early-to-mid-2030s, closing the book on one of the most famous scientific instruments of the century. NASA last raised the orbit of Hubble in 2002, when the Space Shuttle Columbia visited the obs

For a genuine fright this Halloween, you can turn your gaze to the southern border, where ravenous, flesh-eating maggots are festering and have taken to eating people's pets. This week, the country's New World Screwworm (NWS) infestation spread to a third state, Arizona, which joins New Mexico and Texas in being plagued by the horrifying parasites. To date, 74 animal cases have been identified in
Along with the rest of the world, we at Ars are mourning Sir Patrick Stewart —the beloved award-winning actor best known as Captain Jean-Luc Picard in Star Trek: The Next Generation and Professor Charles Xavier in the X-Men franchise—who died Wednesday at the age of 86. A statement released by Stewart's representatives said: We announce with great sorrow the passing of Sir Patrick Stewart yesterd

Boom Supersonic CEO Blake Scholl recently declared “it’s time for a renaissance in energy and in supersonic flight” as the supersonic airliner company unveiled a Colorado factory dedicated to making gas turbines for AI data centers. But Boom may be facing turbulence after early backers for both ventures have questioned the company’s delivery timeline or backed out entirely. One of the company’s f
An official extension for Anthropic’s Claude model was backdoored and threatened as many as 5,000 developers' machines, multiple sources reported Friday. Anthropic so far has yet to warn customers of the incident. The compromised package was a VS Code extension available in the marketplace of Cursor, a maker of AI-assisted developer tools, the company said Friday. The malicious version, 2.1.313,
On August 9, 2026, Dartmouth College provost Santiago Schnell wrote a Washington Post op-ed called "Universities are fighting AI cheating. But there’s a deeper problem." This week, Schnell discovered the depths of the problem himself as he resigned from the university after an advisory committee found that he failed to disclose significant AI use in an academic paper and in the Washington Post op
A significant number of patients in the US lie to their doctors to get antibiotics they likely don't need, according to two new studies. While that may not be a startling revelation, the studies drills down on the phenomenon, finding that the lies patients tell are generally bad ones—and yet, they work almost all the time. In the two linked studies published Friday in JAMA Network Open, a team of
As AI tools and agents have continued their march across all aspects of digital life, many companies are trying to use LLMs to improve the experience of purchasing goods and services on the Internet. Thus far, though, a vanishingly small number of people seem to be taking advantage of those capabilities, at least when it comes to using the popular food delivery app DoorDash with an outside AI age
Crater counts tell us that most of the Martian surface is more than 3 billion years old, but pieces of Mars we have on Earth tell a different story. The three main classes of Martian meteorites—shergottites, nakhlites, and chassignites—are all 2.4 billion years old or younger. Until now, only two genuinely ancient Martian meteorites were known: Allan Hills 84001, found in Antarctica, and a jumble
In an announcement released Thursday, Fujifilm said it will invest roughly 10 billion yen (about $63 million) to increase its production capacity fivefold for an unlikely beneficiary of the AI era: magnetic tape. Fujifilm attributes the surge in archiving demand to the spread of generative AI, which the company remarked is producing "exponential growth" in data needs worldwide. The 5x increase in
The US has charged five individuals as part of the first broad federal crackdown on “ghost students”—fraudsters who steal the identities of hundreds of Americans to pose as fake college students and steal student loans. In a press release Thursday, the Department of Justice said it had uncovered a large-scale scheme relying partly on AI. The DOJ seized more than $750,000 in cryptocurrency from “a

A new report from the analytics firm Quilty Space confirms that, outside of China, the world faces a significant shortage of rockets over the next five years. The firm estimates that between now and 2030, there will be a shortfall of about 150 launches compared to demand from satellite operators and civil space agencies. If demand from the US military is added in—and SpaceX does not extend the Fa
General Motors marketed its Smart Driver system as a way for parents to monitor teen drivers or for adults to track their driving behavior. But in 2024, it emerged that GM had been sharing that data with brokers. Those brokers then sold the data to insurance companies , and some drivers found that their insurance became more expensive as a result. To make matters worse, many of those drivers clai
Binance has suspended all withdrawals after the world’s largest cryptocurrency exchange fell victim to what appears to be the biggest heist in history. The exchange put the “estimated total impact” of the hack at about $6.3 billion and said around $3 billion of affected assets, mainly stablecoins that act as cash for the crypto market, had been frozen. But analysts at Elliptic said the attacker h
Nissan provided flights from Washington, DC, to Santa Barbara, California, and accommodation so Ars could drive the Rogue Hybrid. Ars does not accept paid editorial content. Nissan has a new version of its bestselling Rogue SUV, and it’s launching the model here with the latest version of its e-Power hybrid system, which Ars tested in February. Most hybrid cars you can buy today are parallel hybr

In 2015, biomedical entrepreneur Elizabeth Holmes was Silicon Valley's golden girl, lauded as the youngest and richest self-made female billionaire thanks to the company she founded, Theranos, which was valued at $9 billion at the height of its success. Then it all came crashing down when accusations of fraud surfaced about the company's signature blood-testing device, culminating in a sensationa
Welcome to Edition 9.17 of the Rocket Report! It's been a while since an American company announced plans for a medium-lift new launch vehicle, but that's what happened this week when a startup named Cowboy Space revealed specs for its Big Iron rocket, named for the classic country-western song by Marty Robbins. I'm a huge fan of the name. Maybe Cowboy Space is striking while the iron is hot as t

In the future, you won’t be able to use Reddit without logging in. Reddit CEO Steve Huffman confirmed the impending change in a letter (PDF) to shareholders today about Q3 performance. He said that Reddit is shifting “to a logged-in-only experience," adding: Moving to primarily logged-in will ensure our users have the best Reddit experience possible, and can find the content and communities most
Microsoft is beginning the rollout of a Windows 11 preview update that finally addresses a persistent power user complaint with the operating system: the right-click menu that obliterated years of muscle memory on command locations and hid others behind an additional click. The timing is notable, as the announcement comes alongside Microsoft's quarterly financial report, which showed a continued
The Pentagon inspector general's office declined a request from US senators to investigate restrictions recently imposed on the Ukraine military's use of SpaceX's satellite network. Ukraine, which uses SpaceX's Starlink service and the military version known as Starshield, said earlier this month that military drones lost satellite connectivity when traveling above 161 kilometers per hour (100 mi
President Donald Trump has declared the imports of foreign-made factory robots to be a national security threat—ordering new US negotiations with trading partners while holding out the possibility of imposing new tariffs on such robot imports in the future. Issued on October 28, Trump’s presidential proclamation represents heightened government scrutiny of foreign-made industrial robots that coul
Donald Trump apparently is so aligned with Nvidia CEO Jensen Huang—who has become the president’s key advisor on AI —that he ignored intelligence indicating that Huang was the target of a “Chinese spy plot,” and did so partly to protect Nvidia’s stock. The New York Times spoke with people briefed on US intelligence agencies’ surveillance and granted them anonymity to discuss findings drawn from “

Rather than directly converting photons into electricity, concentrated solar energy uses mirrors to turn sunlight into heat, which can then be used to drive traditional generating turbines. Up to about a decade ago, there was a case to be made that concentrated solar energy had a bright future, as improvements in heat storage had turned it into a way to generate power around the clock. It wasn't
Google parent Alphabet reported its Q3 financial results on Wednesday afternoon, showing a healthy rise in revenue for the months of July to September. But the company's stock price has taken a beating, marking one of the largest post-earnings drops in its history. It comes down to several troubling aspects of the new report, including an admission by the company that AI search isn't earning as m
An unprecedented leak of Department of Homeland Security records has exposed details of more than 41,000 employees or contractors who work for the department and its constituent agencies. The records include email addresses, phone numbers, and office addresses, but also references to internal systems and sensitive information on undercover and surveillance programs.
