Those musical mice might be fictional, but singing mice actually do exist—though their songs don’t sound anything like Gus Gus’ or Alvin’s. Some mice squeak out tunes to woo females, though they aren’t always audible to human ears. But Scotinomys teguina, more commonly known as Alston’s singing mouse, scurries through Central American cloud forests and breaks into audible song to communicate and find mates. And interestingly, male mice will often engage in fast-paced back-and-forth singing duels, the response speed of which has only been matched by two agitated, arguing Aaron Sorkin characters....

But while chef’s knives are the superstar when it comes to cooking tools, you can’t expect one to execute intricate work, like deseeding a chili. You’d need a different blade for that, which you can find in a set like the Seido Japanese Master Chef Knife Set. This knife collection packs eight various blades that can do nearly any kind of cutting, and for a limited time, you can get it on sale for $89....

Check out a video of the little machine in action—it’s pretty darn cute. “Animals are capable of precise and agile locomotion using vision. Replicating this ability has been a long-standing goal in robotics,” the Carnegie Mellon research team explains in their YouTube video‘s description, before explaining that the robot’s systems were first trained through trial and error in simulation environments of areas like staircases and stepping stones. Once the team completed that phase, their four-legged walker utilized its onboard video camera to process what was in front of it while referring back to its previous reinforcement training to adapt as needed....

Humans may have perfected sex (or at least made the most earnest efforts to try), but we definitely didn’t invent it. So who did? Sexual reproduction is around 2 billion years old, but the way bacteria swap genes isn’t really what we mean when we talk about the birds and the bees, and ancient red algae that relied on ocean currents to sweep their sperm cells to receptive partners doesn’t sound much sexier....

When MAGIS-100 is complete, physicists plan to use it for detecting hidden treasures: dark matter, the mysterious invisible something that’s thought to make up much of the universe; and gravitational waves, ripples in space-time caused by cosmic shocks like black holes collisions. They hope to find traces of those elusive phenomena by watching the quantum signatures they leave behind on raindrop-sized clouds of strontium atoms. But actually observing those atoms is trickier than you might expect....

The 3-centimeter-long LaPaz rock was found in 2002 during an American meteorite hunting expedition in Antarctica. (Yes, those are a thing, and they are as adventurous and treacherous and you might imagine.) It was immediately classified as a carbonaceous chondrite (stony, non-metallic meteorites that haven’t changed much since they formed about 4.6 billion years ago, when the solar system was just coming into form). The mineralogy and chemistry of a meteorite can often illustrate what the early solar system looked like, and the group of chondrites the LaPaz meteorite belongs to are particularly interesting for the amount of preserved organic minerals and material they possess....

In recent years, there has been an abundance of simulators on the market. Worry not if it’s overwhelming, all you have to look for is one that enables you to practice in a realistic golf environment, ideally with built-in tools that help you analyze your swing and point out your weaknesses so you can work on them. The SLX MicroSim may just be what you need, and for a limited time, you can get it on sale for 7 percent off....

The Army describes its goal as “maintaining overmatch,” a supremely awkward phrase meant to encompass everything that leads to victory in battle. This could include superior numbers of soldiers, better-positioned and longer-ranged artillery, or simply picking a fight in the right place where an opponent is unprepared. If there’s a reason to revert to jargon in explaining the how and why of winning, it’s because superiority in battle and at war can take many forms, and it’s hard to guarantee an advantage in every one of them....

Weber’s Connect doesn’t simply measure temperature—it actually hopes to guide cooks through the process of making perfectly charred meat. When you set up the Connect, you’ll have to download the dedicated app. Our test unit needed several hours of charging right out of the box (can’t have it dying during a cook) and then required several firmware updates before it would get up and running. The process wasn’t difficult at all, but it was somewhat time consuming, so do it the night before you plan to smoke anything unless you don’t mind applying software updates at 4 AM while the smoker is heating up....

If you have a Windows 11 tablet or a laptop that can transform into one (a 2-in-1), you’ll see that the OS can automatically adjust some settings itself when it notices there are no input peripherals attached and you’re just using touch to move around the system—for example, the icons on the taskbar get a little bit bigger and a little more spaced out. But there are also options you can adjust manually to make sure your Windows 11 tablet experience is the best it can be—from increasing the size of on-screen text to bringing up the software keyboard built into Windows 11....

Right now this research is very much still in the lab, and the researchers aren’t yet sure exactly how far they can push it. But it doesn’t take much to imagine the possibilities for a steam generator that runs solely on water and sunlight. The technology works by mixing a small amount of either carbon or gold-coated silicon dioxide nanoparticles, each just one-tenth the diameter of a single human hair, with water in a glass vessel....

Workers (who are often paid minimum wage) are often forced to leave holiday dinners with family and friends early in order to open up doors early for camped-out customers. Retail employees have been injured or even trampled to death in the past over Black Friday sales in the past. Videos of shoppers physically fighting each other over discounted items have made headlines for several years. But the major shopping day comes at other costs....

Using what you have There are some steps you can take if you want to make dark content look as good as possible without shelling out for a fancier TV. For instance, turning off overhead lights is a great idea largely because it will help fight reflections on your screen. A TV’s glossy surface will reflect light sources that compete with the actual picture, so turning out the lights and trying to get a movie theater-like setting is a good move, but darker isn’t necessarily better....

The news, first brought to public attention by The Washington Post on Wednesday evening and subsequently covered by multiple outlets, traces the major security exploitation to 2021—which, admittedly, was well before Musk’s $44 billion purchase of the social media platform in October 2022. The files, posted to an online hacking forum via an anonymous account “StayMad” under the title “Breached,” were reportedly amassed via a former API vulnerability that allowed them to search user info attached to over 200 million accounts....

But when brought to actual war, the emitters in turn are a way to make an enemy’s sensors less reliable, confounding adversarial pilots about what is real and what is merely an electromagnetic mirage. These “low-cost emitters were built for ranges inside the U.S. but now are in the hands of Ukrainians,” reported Aviation Week, citing Air Force Chief of Staff Charles Q. Brown Jr. “The emitters can replicate surface-to-air missiles and aircraft, and are a cheap, innovative way to further complicate the air picture for Russia....
