In turn, the delay in network state propagations spilled over to a network load balancer that AWS services rely on for stability. As a result, AWS customers experienced connection errors from the US-East-1 region. AWS network functions affected included the creating and modifying Redshift clusters, Lambda invocations, and Fargate task launches such as Managed Workflows for Apache Airflow, Outposts lifecycle operations, and the AWS Support Center. For the time being, Amazon has disabled the DynamoDB DNS Planner and the DNS Enactor automation worldwide while it works to fix the race condition and add protections to prevent the application of incorrect…

Until recently, Iceland was the only country in the world to be free of one of the most maddening and dangerous insects: mosquitoes. But if you’re thinking that a second nation has been declared mosquito-free, brace yourself for some bad news. The Nordic island has just confirmed the discovery of mosquitoes in the municipality of Kjós. “At dusk on the evening of 16 October I noticed a strange-looking fly,” said presumed Icelander Björn Hjaltason, as reported by RÚV English. “I immediately had a suspicion about what…
Measured sycophancy rates on the BrokenMath benchmark. Lower is better. Measured sycophancy rates on the BrokenMath benchmark. Lower is better. Credit: Petrov et al GPT-5 also showed the best “utility” across the tested models, solving 58 percent of the original problems despite the errors introduced in the modified theorems. Overall, though, LLMs also showed more sycophancy when the original problem proved more difficult to solve, the researchers found. While hallucinating proofs for false theorems is obviously a big problem, the researchers also warn against using LLMs to generate novel theorems for AI solving. In testing, they found this kind of…
Sign Up For Goods 🛍️ Product news, reviews, and must-have deals. The criteria was simple … the choice was anything but: pick the best audio products we employed and experiences we enjoyed in 2025. Share our obsession with tech that lets us press play and bliss out. But we view and review as many headphones, earbuds, speakers, and components as we can get our hands on and ears in every year, so we needed to narrow it down to what gave us goosebumps. We chased gear that disappears and kit with an undeniable character, remembered what purposefully seduced and fearlessly…
For millennia, some of the world’s largest filter-feeding whales, including humpbacks, fin whales, and blue whales, have undertaken some of the longest migrations on earth to travel between their warm breeding grounds in the tropics to nutrient-rich feeding destinations in the poles each year. “Nature has finely tuned these journeys, guided by memory and environmental cues that tell whales when to move and where to go,” said Trisha Atwood, an ecologist and associate professor at Utah State University’s Quinney College of Agriculture and Natural Resources. But, she said, climate change is “scrambling these signals,” forcing the marine mammals to veer…

The oddest, and most memorable, interaction I had with ChatGPT Atlas occurred as I scrolled around on Bluesky and asked it to highlight any trends it saw. (ChatGPT listed “political anxiety” and “everyday absurdism” as two of the trends on my timeline.) I was curious what would happen if I opened my Bluesky DMs, which amounted to just a few old messages from friends. So I asked the bot what it would see if I opened that more private page.“Opening your DMs won’t expose anything to me—I’ll simply stop ‘seeing’ the page until you go back to a public view…

Listening to music is fine, as are podcasts and audiobooks, but anything that requires looking down at a page or screen for longer than a few moments leaves me feeling nauseous. I was intrigued, then, when I stumbled on an iPhone feature that’s supposed to prevent, or at least reduce, carsickness. The feature is called Vehicle Motion Cues and it overlays dots on the left and right side of your screen. Those dots move as the vehicle you’re riding does things…
People take a lot of pride in their bedroom abilities. Saatva takes great pride in crafting luxurious, handmade mattresses. To maintain the good work in both situations, the Saatva Classic features an innerspring construction very conducive to lovemaking. There are actually two coil types at play here: pocketed coils beneath the pillow top, and firmer traditional coils at the base. Pocketed coils are better at responding to the situation above them, as they can provide individualized support that homes in on high-weight areas. Whether that’s your lower back while you’re sleeping, or your hands and knees when you’re more active,…

With an icy stare and pep in its step, the big cat skips away with the lifeless bird. This is the scene photographer Dennis Stogsdill witnessed and his image of the encounter earned top honors at the 2025 Wildlife Photographer of the Year awards in the “Behaviour: Mammals” category. A record-breaking 60,636 entries from 113 countries and territories entered this year’s contest, now in its 61st year. South African wildlife photographer…
