The Linux-based operating system that powers Valve’s Steam Deck is one of that handheld gaming PC’s key selling points. While there are a growing number of handhelds that have hardware that looks better on paper, so far they all ship with Windows, an operating system that supports a vast number of PC games, but which […]

Nvidia has good news and bad news for people building or buying gaming PCs.

The good news is that three of its four new RTX 50-series GPUs are the same price as or slightly cheaper than the RTX 40-series GPUs they're replacing. The RTX 5080 is $999, the same price as the RTX 4080 Super; the 5070 Ti and 5070 are launching for $749 and $549, each $50 less than the 4070 Ti Super and 4070 Super.

The bad news for people looking for the absolute fastest card they can get is that the company is charging $1,999 for its flagship RTX 5090 GPU, significantly more than the $1,599 MSRP of the RTX 4090. If you want Nvidia's biggest and best, it will cost at least as much as four high-end game consoles or a pair of decently specced midrange gaming PCs.

Most scientific literature is published in for-profit journals that rely on subscriptions and paywalls to turn a profit. But that trend has been shifting as various governments and funding agencies are requiring that the science they fund be published in open-access journals. The transition is happening gradually, though, and a lot of the historical literature remains locked behind paywalls.

These paywalls can pose a problem for researchers who aren't at well-funded universities, including many in the Global South, which may not be able to access the research they need to understand in order to pursue their own studies. One solution has been Sci-Hub, a site where people can upload PDFs of published papers so they can be shared with anyone who can access the site. Despite losses in publishing industry lawsuits and attempts to block access, Sci-Hub continues to serve up research papers that would otherwise be protected by paywalls.

But what it's serving up may not always be the latest and greatest. Generally, when a paper is retracted for being invalid, publishers issue an updated version of its PDF with clear indications that the research it contains should no longer be considered valid. Unfortunately, it appears that once Sci-Hub has a copy of a paper, it doesn't necessarily have the ability to ensure it's kept up to date. Based on a scan of its content done by researchers from India, about 85 percent of the invalid papers they checked had no indication that the paper had been retracted.

The piano-mover puzzle involves trying to transport an oddly shaped load across a constricted environment with various obstructions. It's one of several variations on classic computational motion-planning problems, a key element in numerous robotics applications. But what would happen if you pitted human beings against ants in a competition to solve the piano-mover puzzle?

According to a paper published in the Proceedings of the National Academy of Sciences, humans have superior cognitive abilities and, hence, would be expected to outperform the ants. However, depriving people of verbal or nonverbal communication can level the playing field, with ants performing better in some trials. And while ants improved their cognitive performance when acting collectively as a group, the same did not hold true for humans.

Co-author Ofer Feinerman of the Weizmann Institute of Science and colleagues saw an opportunity to use the piano-mover puzzle to shed light on group decision-making, as well as the question of whether it is better to cooperate as a group or maintain individuality. "It allows us to compare problem-solving skills and performances across group sizes and down to a single individual and also enables a comparison of collective problem-solving across species," the authors wrote.

Lenovo announced a laptop today that experiments with a new way to offer laptop users more screen space than the typical clamshell design. The Lenovo ThinkBook Plus Gen 6 Rollable has a screen that can roll up vertically to expand from 14 inches diagonally to 16.7 inches, presenting an alternative to prior foldable-screen and dual-screen laptops.

The laptop, which Lenovo says is coming out in June, builds on a concept that Lenovo demoed in February 2023. That prototype had a Sharp-made panel that initially measured 12.7 inches but could unroll to present a total screen size of 15.3 inches. Lenovo's final product is working with a bigger display from Samsung Display, The Verge reported. Resolution-wise you're going from 2,000×1,600 pixels (about 183 pixels per inch) to 2,000×2,350 (184.8 ppi), the publication said.

Users make the screen expand by pressing a dedicated button on the keyboard or by making a hand gesture at the PC's webcam. Expansion entails about 10 seconds of loud whirring from the laptop’s motors. Lenovo executives told The Verge that the laptop was rated for at least 20,000 rolls up and down and 30,000 hinge openings and closings.
