After seeking advice on health topics from ChatGPT, a 60-year-old man who had a "history of studying nutrition in college" decided to try a health experiment: He would eliminate all chlorine from his diet, which for him meant eliminating even table salt (sodium chloride). His ChatGPT conversations led him to believe that he could replace his sodium chloride with sodium bromide, which he obtained over the Internet.

Three months later, the man showed up at his local emergency room. His neighbor, he said, was trying to poison him. Though extremely thirsty, the man was paranoid about accepting the water that the hospital offered him, telling doctors that he had begun distilling his own water at home and that he was on an extremely restrictive vegetarian diet. He did not mention the sodium bromide or the ChatGPT discussions.

His distress, coupled with the odd behavior, led the doctors to run a broad set of lab tests, revealing multiple micronutrient deficiencies, especially in key vitamins. But the bigger problem was that the man appeared to be suffering from a serious case of "bromism." That is, an excess amount of the element bromine had built up in his body.

Human remains from 11 individuals recovered from El Mirador Cave in Spain showed evidence of cannibalism, archaeologists have concluded. According to a new paper published in the journal Scientific Reports, the cannibalism was likely the result of a violent episode between competing Late Neolithic herding communities about 5,700 years ago.

“Cannibalism is one of the most complex behaviors to interpret, due to the inherent difficulty of understanding the act of humans consuming other humans," said co-author Palmira Saladié, a researcher at IPHES-CERCA and the Universitat Rovira i Virgili (URV). "Moreover, in many cases we lack all the necessary evidence to associate it with a specific behavioral context. Finally, societal biases tend to interpret it invariably as an act of barbarism.”

The El Mirador Cave is located at Sierra de Atapuerca , an archaeological site in the Burgos province of northern Spain. There is prior evidence of cannibalism at the Atapuerca site, including the remains of six Early Bronze Age humans, which included skull caps possibly used as containers during ceremonial consumption. In addition, since 1994, more than 160 bone fragments have been recovered from the Aurora Stratum (TD-6) in the Gran Dolina cavern at Sierra de Atapuerca. Over 30 percent of those fragments showed signs of butchering and consumption, such as slice marks, scrape marks, and chop marks.

On Thursday, OpenAI announced GPT-5 and three variants—GPT-5 Pro, GPT-5 mini, and GPT-5 nano—what the company calls its "best AI system yet," with availability for some of the models across all ChatGPT tiers, including free users. The new model family arrives with claims of reduced confabulations, improved coding capabilities, and a new approach to handling sensitive requests that OpenAI calls "safe completions."

It's also the first time OpenAI has given free users access to a simulated reasoning AI model, which breaks problems down into multiple steps using a technique that tends to improve answer accuracy for logical or analytical questions.

GPT-5 represents OpenAI's latest attempt to unify its various AI capabilities into a single system. The company says the GPT-5 family acts as a "unified system" with a smart, efficient model that answers most questions, a deeper reasoning model called "GPT-5 thinking" for harder problems, and a real-time router that decides which approach to use based on conversation type, complexity, tool needs, and user intent. Like GPT-4o, GPT-5 is a multimodal system that can interact via images, voice, and text.

REIDEN, Germany—There is a lot to be said for testing a car on the roads it was developed on. A Kei car , for example, makes more sense in downtown Tokyo than on one of Nashville's arterial highways , surrounded by construction trucks. Likewise the German supersedans. For decades, an arms race has been conducted between rival engineers in Munich, Ingolstadt, Stuttgart, and Zuffenhausen, each trying to best the others and build the ultimate four-door, four-wheel Autobahn crusher, fit for the fattest fat-cat captains of industry. The Panamera Turbo S E-Hybrid is Porsche's entry into this heavyweight bout.

In most of the world, the horsepower war has little relevance. Huge engine outputs, short acceleration times, and ridiculous top speeds that result from a casual indifference to fitting a speed limiter are at best of interest to the bench racers and are otherwise academic. Not so in Germany. After inventing the motorway in 1932, the country declined to impose speed limits on some sections, a practice it maintains as long as there's daylight and the weather is good. And drivers there make use of that privilege—in the fast lane, at least.

Seen in this context, the $239,000 Panamera Turbo S starts making more sense. It's the most powerful Panamera to date, combining a (fruity-sounding) 591 hp (441 kW) 4.0 L V8 that has been reworked compared to the version you might find under the hood of the last version . New monoscroll turbochargers and a higher peak combustion chamber pressure help warm up the catalytic converters quicker, and instead of cylinder deactivation at low load, the engine can change how much and how long it opens its intake valves, shortening the travel and duration under those conditions.

During what's supposed to be a year of redemption, Sonos has announced that its gadgets will become more expensive this year, complicating the company's comeback plans.

Tariffs that US President Donald Trump announced last week take effect today, including a 19 percent tariff on goods imported from Malaysia (the levy is said not to apply to semiconductors and was cut down from a 25 percent tariff that Trump threatened in July.) Among other countries affected is Vietnam, which now sees a 20 percent tariff (down from the 46 percent rate announced in April).

Sonos makes all its audio products in the US, “short of a few accessories and our passive speaker partnership with Sonance," which entails in-wall and in-ceiling speakers , in Malaysia and Vietnam, Sonos CEO Tom Conrad said yesterday, per a transcript of Sonos’ Q3 2025 earnings call. The new CEO explained:

It's now clear that Apple plans to survive Donald Trump's trade war by playing to the president's ego.

On Wednesday, Trump announced that Apple would be exempt from a threatened 100 percent tariff on semiconductors that could have driven up the cost of iPhones globally, Reuters reported . In an apparent effort to secure this exemption, Apple promised to increase its total investment commitment in the US by $100 billion, while also gifting Trump a one-of-a-kind statue that Apple CEO Tim Cook had engraved with Trump's name.

It serves as a bizarre love letter to Trump's push to bring tech manufacturing into the US, despite Apple resisting that push for its most popular product.

Framework’s main claim to fame is its commitment to modular, upgradeable, repairable laptops. The jury’s still out on early 2024’s Framework Laptop 16 and mid-2025’s Framework Laptop 12, neither of which has seen a hardware refresh, but so far, the company has released half a dozen iterations of its flagship Framework Laptop 13 in less than five years. If you bought one of the originals right when it first launched, you could go to Framework’s site, buy an all-new motherboard and RAM, and get a substantial upgrade in performance and other capabilities without having to change anything else about your laptop.

Framework’s laptops haven’t been adopted as industry-wide standards, but in many ways, they seem built to reflect the flexibility and modularity that has drawn me to desktop PCs for more than two decades.

That's what makes the Framework Desktop so weird. Not only is Framework navigating into a product category where its main innovation and claim to fame is totally unnecessary. But it’s actually doing that with a desktop that’s less upgradeable and modular than any given self-built desktop PC.

The Subaru WRX has always been the equivalent of an automotive shrug. Not because it lacks character but because it simply doesn't care what others think. It's a punk rock band with enough talent to fill stadiums but band members who don't seem to care about chasing fame. And the STI versions of yesteryear proved so talented that fame chased them.

For 2025, Subaru updated the WRX to now include the tS, which at first glance appears to be the same flannel-wearing street fighter. But looks can be deceiving. The tS hides sharpened tools underneath, translating to better handling and responsiveness.

What does “tS” really mean?

Subaru positions the tS as being tuned by STI, but it's not an STI return. Sure, that's technically true; only Subaru can name something STI. And to be clear, there's no extra power here, no gigantic wing that takes out flocks of birds, and no pink STI badge on the trunk. But the tS is imbued with enough STI-ness to make a case.

Donald Trump has called for the newly appointed chief executive of Intel, Lip-Bu Tan, to resign, alleging that the semiconductor industry veteran is “highly conflicted.”

“The CEO of INTEL is highly CONFLICTED and must resign, immediately,” Trump said in his post on his Truth Social website on Thursday. “There is no other solution to this problem.”

The US president’s post did not provide details of Tan’s alleged conflicts of interest. Trump’s broadside follows a letter from Republican Senator Tom Cotton to the US chipmaker’s board chair this week expressing “concern about the security and integrity of Intel’s operations” and Tan’s ties to China.
