The FBI is offering $10 million for information about the China-state hacking group tracked as Salt Typhoon and its intrusion last year into sensitive networks belonging to multiple US telecommunications companies.

Salt Typhoon is one of a half-dozen or more hacking groups that work on behalf of the People’s Republic of China. Intelligence agencies and private security companies have concluded the group has been behind a string of espionage attacks designed to collect vital information, in part for use in any military conflicts that may arise in the future.

A broad and significant cyber campaign

The agency on Thursday published a statement offering up to $10 million, relocation assistance, and other compensation for information about Salt Typhoon. The announcement specifically sought information about the specific members of Salt Typhoon and the group's compromise of multiple US telecommunications companies last year.

Elon Musk raced to build Colossus, the world's largest supercomputer, in Memphis, Tennessee. He bragged that construction only took 122 days and expected that his biggest AI rivals would struggle to catch up.

To leap ahead, his firm xAI "removed whatever was unnecessary" to complete the build, questioning "everything" that might delay operations and taking the timeline "into our own hands," xAI's website said.

Now, xAI is facing calls to shut down gas turbines that power the supercomputer, as Memphis residents in historically Black communities—which have long suffered from industrial pollution causing poor air quality and decreasing life expectancy—allege that xAI has been secretly running more turbines than the local government knows, without permits.

Google's oldest smart thermostats have an expiration date. The company has announced that the first and second generation Nest Learning Thermostats will lose support in October 2025, disabling most of the connected features. Google is offering some compensation for anyone still using these devices, but there's no Google upgrade for European users. Google is also discontinuing its only European model, and it's not planning to release another.

Both affected North American thermostats predate Google's ownership of the company, which it acquired in 2014 . Nest released the original Learning Thermostat to almost universal praise in 2011, with the sequel arriving a year later. Google's second-gen Euro unit launched in 2014. Since launch, all these devices have been getting regular software updates and have migrated across multiple app redesigns. However, all good things must come to an end.

As Google points out, these products have had a long life, and they're not being rendered totally inoperable. Come October 25, 2025, these devices will no longer receive software updates or connect to Google's cloud services. That means you won't be able to control them from the Google Home app or via Assistant (or more likely Gemini by that point). The devices will still work as a regular dumb thermostat to control temperature, and scheduling will remain accessible from the thermostat's screen.

It's long been the stuff of science fiction: humans achieving immortality by uploading their consciousness into a silicon virtual paradise, ruled over by a benevolent super-intelligent AI. Or maybe one dreams of leaving a dying Earth to colonize Mars or other distant planets. It's a tantalizing visionary future that has been embraced by tech billionaires in particular. But is that future truly the utopian ideal, or something potentially darker? And are those goals even scientifically feasible?

These are the kinds of questions astrophysicist and science journalist Adam Becker poses in his new book, More Everything Forever: AI Overlords, Space Empires, and Silicon Valley's Crusade to Control the Fate of Humanit y. Becker's widely praised first book, What Is Real? , focused on competing interpretations of quantum mechanics and questioned the long dominance of the so-called Copenhagen interpretation championed by Niels Bohr, among other luminaries. This time around, he's tackling Silicon Valley's far-reaching ideas about the future, which have moved out of online subcultures and into mainstream culture, including our political discourse.

"It seemed like it was only going to become more relevant and someone needed to speak out about it, and I didn't see enough people connecting the dots in a way that looked right to me," Becker told Ars. "One current critique of Silicon Valley is that they moved fast and broke democracy and institutional norms. That's true. Another is that they're contemptuous of government, and I think that's true, too. But there wasn't much critique of their visions of the future, maybe because not enough people realized they meant it. Even among Silicon Valley critics, there was this idea that at the very least, you could trust that the statements they made about science and technology were true because they were experts in science and technology. That's not the case."

Nearly a year after announcing the feature , Microsoft is finally ready to roll the controversial Windows Recall feature out to the general public, the company announced today on its Windows Experience Blog .

Only available on Copilot+ PCs, a subset of Windows 11 systems sold within the last year or so, Recall takes continuous screenshots of everything you do on your PC, saving them, scraping text from them, and saving it all in a searchable database. This obviously has major security and privacy implications—anyone who can get access to your Recall database can see nearly everything you've done on your PC—which is why Microsoft's initial rollout attempt was such a mess.

Recall's long road to release involved a rushed initial almost-launch, harsh criticism of its (then mostly nonexistent) security protections, multiple delays , a major under-the-hood overhaul , and five months of testing in Microsoft's Windows Insider beta program. Microsoft signaled that Recall was nearly ready for release two weeks ago when it came to the near-final Release Preview channel .

Router maker TP-Link is facing a criminal antitrust investigation into whether it engaged in predatory pricing, Bloomberg reported yesterday. TP-Link was already facing government scrutiny over its ties to China.

"The US is conducting a criminal antitrust investigation into pricing strategies by TP-Link Systems Inc., a California-based router maker with links to China whose equipment now dominates the American market, according to people familiar with the matter," Bloomberg wrote. "Beyond pricing, a focus of the inquiry is also whether the company's growing US market share represents a threat to national security... The scrutiny began in late 2024 under the Biden administration and has continued under President Donald Trump."

Justice Department prosecutors are investigating whether TP-Link engaged in a predatory pricing scheme that "involves selling goods below cost in order to gain market share before raising prices once competitors have either been hobbled or eliminated," the report said.

The latest anomaly in the climate system that can’t be fully explained by researchers is a record annual jump in the global mean concentration of carbon dioxide in the atmosphere measured in 2024.

The concentration, measured in parts per million, has been increasing rapidly since human civilizations started burning coal and oil in the mid-1800s from the pre-industrial level of 280 ppm.

The US Department of Transportation issued revised rules for autonomous and partially automated vehicles on Thursday. Despite fears that the Trump administration would roll back safety regulations as it has for air and water standards, crashes involving autonomous or partially automated vehicles must still be reported to the government. And now, domestic autonomous vehicle developers will be able to benefit from exemptions previously only offered to foreign companies.

"This administration understands that we're in a race with China to out-innovate, and the stakes couldn’t be higher," said US Transportation Secretary Sean Duffy in a statement. "As part of DOT's innovation agenda, our new framework will slash red tape and move us closer to a single national standard that spurs innovation and prioritizes safety," Duffy said.

The National Highway Traffic Safety Administration is keeping its Standing General Order , which requires manufacturers of autonomous or partially automated vehicles to report crashes that occur with such systems on public roads. Crashes using either autonomous driving systems or a partially automated system like GM's Super Cruise or Tesla's Autopilot must be reported within 10 days if anyone involved was killed or taken to hospital, if a vulnerable road user was hit, if the airbags deployed, or if the vehicle had to be towed away from the crash.

We think of moths and butterflies as relatively harmless creatures, but there are certain species with a darker side—for example, carnivorous caterpillars that eat aphids, butterflies that drink alligator tears, or "vampire" moths that feed on livestock blood. Add to that list the newly discovered "bone collector" caterpillar, which conducts daring raids on spider webs for sustenance, camouflaging itself in the body parts of already-consumed insects to avoid being eaten. Not only that, but according to a new paper published in the journal Science, the caterpillars can tailor those insect parts, nibbling away at any excess material to ensure a proper fit.

Daniel Rubinoff, an entomologist at the University of Hawaii, Manoa, studies a genus of moths found in Hawaii called Hyposcoma , or as he has dubbed their larval form, "Hawaiian Fancy Case" caterpillars, so named because they spin their own casings, adding to them as they grow, although the materials used can vary widely.  There are now more than 600 species within this genus, many of them not yet officially described, so it was a rich research area to explore.

The discovery of the bone collector species was serendipitous. "You never forget your first bone collector," Rubinoff told Ars. His team was on Oa'hu looking for Hyposcoma when they came across a little tree hollow and spotted something at the bottom that at first glance just looked like "a bag of bug bits." The caterpillar then stuck its head out, and the researchers realized it was a new kind of case. Rubinoff assumed that the spider web also found in the tree hollow was a coincidence; the caterpillar just used the materials readily available in the tree hollow to make its fancy case.
