The World Is in a Polyester Crisis. One Company Is Trying to Recycle a Way Out

I’m on an overnight flight from New York to Frankfurt, Germany, and the accoutrements given to me in business class have a sustainable sheen. Both the polyester blanket and polyester flight kit proudly claim they are made of fabric spun from recycled plastic bottles. But doesn’t United Airlines know that recycled bottles are so yesterday’s green material? No, the new hot and hyped technology is recycling polyester into polyester. And I’m on my way to observe the most well-capitalized innovation

MLB is testing robotic umpires in Spring Training, eyes 2026 implementation

Forward-looking: Major League Baseball is testing a computerized system for calling balls and strikes during spring training exhibition games. This Automated Ball-Strike System (ABS), which has been in development for four years in the minor leagues, could aid MLB home plate umpires as early as 2026.

New Polling Shows Americans Increasingly Disgusted With Elon Musk

Unelected White House budget slasher and richest man in the world Elon Musk's so-called Department of Government Efficiency has ripped through the federal government like a bull in a china shop. The billionaire's hodge-podge team of underqualified 20-somethings — and at least one literal teenager — have already ripped up countless government contracts and fired thousands of federal employees — only to rehire those who were in charge of nuclear security and protecting the US from a looming bird

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.

Did a Rock Hit Your Windshield, or Did Your Windshield Hit a Rock?

You’re driving along, minding your own business, and—TING! Something smacks your windshield. You didn't see it coming, but the glass is cracked. Where the heck did it come from, and why did it hit your windshield? As I always say, you don’t understand something unless you can model it. So let’s try a little thought experiment. We’ll start with a basic scenario, where someone ahead of you drops an object in the road, and then see what we need to make it work. Follow the Bouncing Ball OK, imagi

DeepSeek to open source parts of online services code

In Brief Chinese AI lab DeepSeek plans to open source portions of its online services’ code as part of an “open source week” event next week.

5 Mythical Tales That Need the Big-Screen Treatment After Christopher Nolan’s The Odyssey

There’s a very specific niche of Greek mythology geeks who think about the gods and goddesses at least once a day. Yes, it’s our Roman Empire, and with the news that Christopher Nolan (Interstellar) is going to meticulously assemble the grand myth of The Odyssey for the big screen with quite the epic cast, we’re so ready for it to be our time. Most recently, we’ve gotten a smattering of adaptations here and there—big swings resulting in misses, like Netflix’s Kaos starring Jeff Goldblum as Zeus

I tried Google Photos' AI search and it was surprisingly bad - 3 ways to fix it

Sabrina Ortiz/ZDNET One practical use case for AI natural language processing is being able to search your photos with the ease of a conversational prompt. As a result, Google unveiled a feature called Ask Photos last year and started rolling out early access to users via Google Labs in September. The feature finally rolled out to me -- and the results were surprising. I was excited to try it out for myself. Even though I am a long-time iPhone user, I've used Google Photos for about a decade f

ProtoArc XKM01 CaseUp Combo Review: A Reliable Portable Workstation

The mouse is perfectly adequate too. It's slim but provides enough palm support that my hand doesn't feel like it's cramping up. The scroll wheel and buttons are smooth and responsive. After a short time, I noticed a strange, squeaky noise coming from the left side whenever I'd click. It's not always there, but it's slightly annoying whenever it comes back. Like the keyboard, it charges via USB-C but has a slightly longer battery life of up to 200 days (standby time). The stand is super adjusta

Killer Asteroid Could Be Headed for Some of the World's Most Populous Cities

According to NASA's Jet Propulsion Lab, near-Earth asteroid 2024 YR4 now has a 3.1 percent chance of colliding with our planet on December 22, 2032. That makes it the highest-threat asteroid ever detected, as Euronews reports. As of late January, the probability was sitting at just 1.3 percent, which then rose to 2.1 percent last week before rising yet again. Worse yet, the space agency suggests the asteroid could hit densely populated areas of our planet — if it were to make an impact just un

Trump Orders Musk to Get Air Force One Finished Quickly, Even If It Isn't Fully Safe Yet

What's the worst that could happen? President Donald Trump is running out of patience with Boeing, which was supposed to deliver two new Air Force One planes by the end of his predecessor's term. And guess who he's turning to to speed things up? Elon Musk, who Trump has "empowered" to take measures to get the beleaguered aerospace company to stop dragging its feet, the New York Times reports. Trump's pick for the task isn't surprising, since he's asked the world's richest man to do everything

You can now apply for the 'opportunity to purchase' an RTX 5090 or 5080 from NVIDIA

While graphics cards have been getting almost ludicrously more powerful over the years, it's also been increasingly difficult to actually buy one . In an effort to address this problem, NVIDIA has introduced a plan it's calling Verified Priority Access for its recently released GeForce RTX 50 series of GPUs. Verified Priority Access offers an unspecified number of people the chance to buy either a GeForce RTX 5090 or RTX 5080 Founders Edition graphics card direct from the company. This "opportu

Tesla Cybertruck: all the news about Elon Musk’s futuristic pickup truck

Here’s everything you need to know about Tesla’s first pickup truck, which Elon Musk has called “heart-stopping” and his “personal favorite” of Tesla’s vehicles. Pickups have become more popular lately — their share of the US light vehicle market increased to 17.5 percent in 2019, from just under 13 percent in 2012. They’re also the fastest-growing auto segment in the US. That makes Tesla’s entry into pickups sensible, analysts say. Another pickup perk: pricing. Pickups tend to be expensive. E
