When you plug in a device, you’re usually using a trusted cable. Whether it is USB4 or Thunderbolt 4, you’re expecting blazing-fast transfer speeds up to 40Gbps, as advertised. However, achieving that kind of throughput means the cable has to operate at multi-gigahertz frequencies, and at those frequencies, physics gets pretty unforgiving. It comes down to how electricity and light behave once you push them past a certain distance. Related I stopped buying random USB-C cables after learning what three numbers actually mean USB-C cables are notoriously hard to identify, but these three numbers will help you figure out what…

Summer is here, and with it comes more time in the outdoors. Kids are home from school. Backyard parties galore. And if you’re near a beach, maybe a bonfire or two? Then there’s one of my favorite activities during the warmer months, the backyard movie night. And while some of the smaller Bluetooth speakers are fine for just you and the kids or a date night for two, what if your favorite pastime is being a party host? Maybe you’re the one who enjoys being the DJ at group beach gatherings? If that’s you, if you’re the one who loves…

Threat actors have successfully exploited a vulnerability in PTC Windchill in the wild, marking the first confirmed real-world abuse of the popular product lifecycle management (PLM) platform. The vulnerability is tracked as CVE-2026-12569 and it affects PTC’s Windchill and FlexPLM products. The improper input validation flaw can be exploited by a remote, unauthenticated attacker to execute arbitrary code via specially crafted requests. The cybersecurity agency CISA added the security hole to its Known Exploited Vulnerabilities (KEV) catalog on Thursday, instructing federal agencies to address it by June 28.

ComputingIBM Has Unveiled Chip Technology That Could Help Extend Moore’s Law Another DecadeSophia Chen | MIT Technology Review ($)”To fit more transistors on a chip, engineers across the industry are eyeing a pivot to an approach familiar to urban planners: build up. On Thursday, IBM announced it has created a chip that uses this strategy. The new architecture, known as a nanostack, vertically stacks transistors in two layers on a silicon chip.”Artificial IntelligenceAI Is Designing Radio Chips That Humans Couldn’t Even ImagineKaushik Sengupta | IEEE Spectrum”Some of the…chips look more like modern art than circuit layouts. Yet in many cases,…

It’s hot, hot, hot, and we’re all looking for ways to keep cool. While portable air conditioners are the simplest way to lower the temperature of a room without requiring professional installation, it’s hard to miss the alternatives that are pushed: evaporative coolers. Also known as air coolers, or misting fans in the UK, and swamp coolers in other parts of the world, these devices use a tank of water and are sold as being able to cool the air they blow. With prices way lower than even the cheapest portable AC unit, such as the Vonhaus 12000 BTU High Performance…

We’ve tested a lot of crazy workout gear over the years, from Adidas’ pressurized workout shoes to elaborate virtual coaching booths, but never anything from space.Let me confirm that I haven’t actually worn anything from outer space: this is a workout layer from premium activewear company Walero, which also makes professional-grade motorsport gear. The Walero Active temperature-regulating baselayer incorporates Outlast technology, which is a fabric system originally developed for NASA to clothe its astronauts.The Outlast website says “the most important part of fabrics and materials with this NASA technology is the microencapsulated wax, which is usually won from rapeseed oil.Latest…

Russia-linked APT Turla has been targeting government and military organizations in Ukraine with a new backdoor specifically designed for espionage, Google Threat Intelligence Group (GTIG) reports. Also known as Krypton, Snake, Summit, UAC-0194, Venomous Bear, and Waterbug, Turla has been active since at least 2004. The US officially linked the APT to Russia’s Federal Security Service (FSB) in 2023. According to a fresh GTIG report, Turla has been developing a .NET backdoor tracked as StockStay since 2022, and has been using it in attacks against Ukraine’s government and military, as well as against entities with an interest in Italian foreign…

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech It’s 2026 and we’re still getting new “Toy Story” movies. In fact, we’re now on “Toy Story 5” — and the original was released in 1995, some 31 years ago. How long can Disney and Pixar keep this madness up?  It’s a thought that’s crossed the mind of Tom Hanks, the voice behind series’ rootin’ tootin’ protagonist Woody.  In a recent Entertainment Weekly interview with his co-star Tim Allen (the voice of the franchise’s Buzz Lightyear), Hanks morbidly considered the possibility that when…

Getting a spacecraft to Mars or beyond requires an enormous amount of fuel, most of which has to be hauled from Earth, adding to the overall cost and weight of the spacecraft. NASA has been working on a different approach, one that could be more efficient and effective. It wants to refuel a spacecraft in orbit before heading out for the mission. What’s even more interesting is that the space agency just finished testing a component that could make that possible: a cryocoupler. So what exactly is a cryocoupler, and why does it matter? Think of it as the nozzle…

Pairing your TV with a streaming stick, soundbar, Blu-ray player, and gaming console sounds great until you realize that you now have four remotes and no one in the house knows which one does what anymore. I had this exact problem until I realized my devices had a solution the entire time. It’s called HDMI-CEC, and now that I’ve enabled it, I no longer need to juggle between all those different remotes. Related Smart TV Remote Lost Again?
