The 5 Best Organic Mattress Toppers (2025)

If you're happy with your mattress, you probably aren't reading this, so I'll assume your mattress is either causing you some back pain or you're feeling the pressure points that happen when your body isn't quite suited to what you're sleeping on. In those situations, provided your mattress isn't actually sagging or needing to be replaced, a high-quality mattress topper suited to your body and manner of sleeping can indeed help. Keep in mind that there really is no best mattress topper; there's

The best robot vacuum and mop to buy right now

Robot vacuums that can both mop and sweep your floors have improved significantly in recent years. While they are still not as effective as good ol’ manual labor, if you run them regularly, they will help keep your floors cleaner with much less effort on your part. The difference is that newer “combo” robot vacuum and mop models are designed to actually scrub your floors. The first robot vacuums that could also “mop” simply slapped a thin, flat microfiber pad on the bot that kind of Swiffer-ed

ChatGPT will avoid being shut down in some life-threatening scenarios, former OpenAI researcher claims

Former OpenAI research leader Steven Adler published a new independent study on Wednesday claiming that, in certain scenarios, his former employer’s AI models will go to great lengths to try to avoid being shut down. In a blog post, Adler describes a series of experiments he ran on OpenAI’s latest GPT-4o model, the default model available in ChatGPT, to test the AI’s tendency to favor its own self-preservation, even if it’s at the expense of a user’s safety. In one test, Adler instructed GPT-4

Google, Meta execs blast Europe over strict AI regulation as Big Tech ups the ante

Dado Ruvic | Reuters STOCKHOLM — Executives at U.S. tech giants Google and Meta said that Europe's artificial intelligence industry is being held back by excessive regulation, adding to rhetoric from Donald Trump's administration that the region's strict tech rules are choking innovation. Speaking at the Techarena tech conference in Stockholm, Sweden, public policy chiefs at both Google and Meta used the stage as a platform to voice their concerns about the bloc's strict approach to regulating

What's Behind OpenAI's Recent Growth Spurt to 400M Weekly Users?

ChatGPT maker OpenAI says more than 400 million people a week are now actively using its artificial intelligence tools, a jump from the 300 million it reported this past December. OpenAI touted the figure this week, also telling media outlets that it's doubled its number of paid enterprise users to 2 million since September, and that its developer traffic has also doubled in the last six months. The news may surprise people who expected the rise of China's DeepSeek AI model to disrupt the grow

The best robot vacuums

Robot vacuums are impressive devices that will clean your floors well without complaining (much). As prices have dropped, these busy little bots have become less of a luxury and more of a necessity. They can reach places most standup vacs never see (under beds and sofas) and, thanks to better batteries and robot brains, they rarely get tired of cleaning. I’ve been testing robot vacuums for seven years and have run over 60 robot vacuums all over my house. These are my top picks if you’re looking

How DeepSeek used distillation to train its artificial intelligence model, and what it means for companies such as OpenAI

Chinese artificial intelligence lab DeepSeek roiled markets in January, setting off a massive tech and semiconductor selloff after unveiling AI models that it said were cheaper and more efficient than American ones. But the underlying fears and breakthroughs that sparked the selling go much deeper than one AI startup. Silicon Valley is now reckoning with a technique in AI development called distillation, one that could upend the AI leaderboard. Distillation is a process of extracting knowledge

Write Warz developers on how creative writing makes a hilarious party game

Write Warz is the recently launched debut title of Boltz Entertainment, a co-op party game that turns the act of storytelling into strategic (and often funny) warfare against your opponents. Building on the tradition of Jackbox-style titles like Quiplash or RiffTrax, Write Warz instead offers a longer-form avenue of storytelling between friends, as up to 6 players can join together to build the narrative. The game launches on Steam in early access on March 6, with horror and pirate-based themes.

ChatGPT’s weekly user base has exceeded the entire US population

Calvin Wankhede / Android Authority TL;DR ChatGPT has crossed 400 million weekly users, marking a 33% increase in just three months despite rising AI competition.

OpenAI’s enterprise business is also expanding, now with 2 million paying users as companies integrate AI into their workflows. The AI chatbot battle continues to reshape the tech landscape, but OpenAI — the company behind ChatGP

OpenAI bans Chinese accounts using ChatGPT to edit code for social media surveillance

OpenAI has banned the accounts of a group of Chinese users who had attempted to use ChatGPT to debug and edit code for an AI social media surveillance tool, the company said Friday . The campaign, which OpenAI calls Peer Review, saw the group prompt ChatGPT to generate sales pitches for a program those documents suggest was designed to monitor anti-Chinese sentiment on X, Facebook, YouTube, Instagram and other platforms. The operation appears to have been particularly interested in spotting call

The CRPG Renaissance, Part 3: TSR Is Dead

“How do you make a small fortune in tabletop gaming?” runs an old joke. The punchline, of course, is that you come to that market with a large one. The tabletop truly is a brutally challenging place to try to earn money, one which you have to be either wildly deluded or unbelievably passionate to even contemplate entering. Nevertheless, people have been making a go of it there for quite some decades by now. We’ll give them the benefit of the doubt and assume that love rather than mental illnes

Report: OpenAI plans to shift compute needs from Microsoft to SoftBank

In Brief OpenAI is forecasting a major shift in the next five years around who it gets most of its computing power from, The Information reported on Friday. By 2030, OpenAI expects to get three-quarters of its data center capacity from Stargate, a project that’s expected to be heavily financed by SoftBank, one of OpenAI’s newest financial backers. That represents a major shift away from Microsoft, OpenAI’s biggest shareholder, who fulfills most of the startup’s power needs today. The change w

ChatGPT's AI agent Operator is now available for most Pro users

Oppo's new foldable phone is one of the thinnest I've seen - and I hope OnePlus and Samsung follow suit

Prakhar Khanna/ZDNET The world's thinnest book-style foldable, the Oppo Find N5, is finally here. I've had it for a week, and it has surprised me in more ways than one -- both positively and negatively. At 8.93mm thick when folded, it's closer to slab phones than any other foldable has ever been. But that slimness didn't come without compromises. Judging by the on-paper camera specifications, I expected it to be underwhelming, but it's better than other foldable phones in almost every regard.

Microsoft's quantum chip Majarona 1 is a few qubits short

Microsoft says its Majorana 1 contains eight topological qubits and can scale to a million, though the details on how it will scale are scant. Microsoft Quantum Microsoft's quantum computing scientists announced they have finally realized a long-held goal of building a "topological qubit", the equivalent of a transistor for ordinary chips, that may help advance quantum computing. The qubit is the functional element of a quantum chip, called Majorana 1, based on an exotic particle, a hybrid of

Sweden Investigates New Cable Break Under Baltic Sea

The European Union vowed on Friday to increase security in the Baltic Sea as the Swedish authorities said they were investigating a new cable break, the latest example of damage to underwater infrastructure in the region. The European Commission, the bloc’s executive arm, said it would take new steps to prevent and detect threats to submarine cables, which carry internet traffic and transmit electricity. The severing of several undersea cables in the Baltic Sea in recent months has raised conc

The $230 MacBook Air Is Real, It’s a Steal, and It’s Flying Off the Shelves

MacBooks are many things — beautifully designed, reliable, sturdy, fast, and powerful among them. Inexpensive, however, is not a word you hear applied to MacBooks often, if ever. Apple is very much a get-what-you-pay-for company, and you pay for quality. Thankfully, there are shortcuts to be found, like the deals StackSocial frequently runs on Grade-A refurbished MacBooks for a fraction of their usual cost.

HP realizes that mandatory 15-minute support call wait times isn’t good support

In an odd approach to trying to improve customer tech support, HP allegedly implemented mandatory, 15-minute wait times for people calling the vendor for help with their computers and printers in certain geographies. Callers from the United Kingdom, France, Germany, Ireland, and Italy were met with the forced holding periods, The Register reported on Thursday. The publication cited internal communications it saw from February 18 that reportedly said the wait times aimed to "influence customers

DeepSeek goes beyond “open weights” AI with plans for source code release

Last month, DeepSeek turned the AI world on its head with the release of a new, competitive simulated reasoning model that was free to download and use under an MIT license. Now, the company is preparing to make the underlying code behind that model more accessible, promising to release five open source repos starting next week. In a social media post late Thursday, DeepSeek said the daily releases it is planning for its "Open Source Week" would provide visibility into "these humble building bl

Game Developers Fear Anti-Trans Measures Could Hit Their Industry Next

Ashley Poprik has never been the model for a video game character. As a writer on projects like Spider-Man 2 and Call of Duty: Black Ops 6, they work on games, not as characters within them. In 2023, however, a cabal of angry gamers was convinced otherwise. They were furious over how Spider-Man 2’s Mary Jane looked; more specifically, they complained, she simply wasn’t hot enough. The problem, these gamers falsely claimed, was that Poprik—then a writing intern with no ability to change a charac
