In February 2023, a cosmic particle detector housed deep in the Mediterranean Sea recorded the arrival of a neutrino with approximately 20 to 30 times more energy than any other neutrino documented previously. Labelled KM3-230213A, the particle had a calculated energy of 220 petaelectronvolts (PeV), far greater than the 10 PeV of the previously most energetic neutrino. The finding generated a lot of excitement among physicists, but raised also many questions.Neutrinos are the most abundant particles in the universe with mass. They are a type of fundamental particle, which means they don’t break down into smaller constituents, and are therefore…

The account was active at least between September 2019 and January 2021, and had the username @PhDofbombsaway. It used several different screen names, including “Dr. Erwin J. Antoni III” and “Dr. Curtis LeMay,” an apparent reference to the US Air Force general who oversaw a campaign of firebombing Japan in World War II, promoted the use of nuclear weapons, and ran for the vice presidency alongside segregationist George Wallace in 1968. The account’s profile picture was a stock image of a fiery mushroom cloud.The account’s persona was that of a deeply loyal Trump supporter engaging in conspiracy theories ranging from…

If I put a box on its side and cannot grasp the product to lift it from its box, then that’s the first strike. WIRED considers accessibility, and this means handles and wheels on heavier air purifiers. When I review a unit, I think about those with less upper body strength moving the appliances, and whether they’d be able to maneuver it around their home. I move air purifiers all around my apartment; I shouldn’t have to bend at the knees to adjust a purifier’s location.Photograph: Lisa Wood ShapiroI was able to move the 50-pound ProX using its hidden handles…

Compare Top 5 Posture CorrectorsHow We Test Posture CorrectorsAccordionItemContainerButtonWe tested each posture corrector, wearing them through the routines of daily life—from sitting at a desk to running errands and working out—for both short and long periods, over several months. No one wants to feel like they’re strapped into armor, so we evaluated wearability by focusing on comfort, breathable materials, and adjustability. Material quality was a priority, and we kept an eye out for signs of wear or damage after consistent use. Size inclusivity was another major factor; we sought options that catered to a range of body types. To ensure…

It’s fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational constant, and Planck’s constant, and they’re “fundamental” in the sense that we can’t derive them theoretically, we can only measure them.We use these in solving physics problems all the time, so it’s easy to take them for granted. But why are there such numbers in nature, and why do they just happen to have those specific values? Because, listen, if they were only slightly different, the universe might be…

If You Have a Dog, Consider These KitsI don’t have a dog, so I didn’t try these at-home DNA test kits for dogs, but these are the kits specifically for dogs from Basepaws and Wisdom Panel, the two companies I’ve tested for my cats.Wisdom PanelBreed Discovery Dog DNA KitWisdom PanelPremium Dog DNA KitWisdom PanelEssential Dog DNA KitHow Does a DNA Testing Kit Work?Pet DNA tests rely on pet owners collecting cells for testing through a cheek swab, where the sample is put into a sealed stabilizing or preserving fluid for transit.

Apple responded with the iPad Pro, which brought more horsepower than anyone knew what to do with. The original iPad had debuted at $499, which Jobs argued would get it into many hands. The Pro was priced like a Mac but was still paired with an operating system designed for prodding web pages, flicking through photos, and finger-painting. Alongside it came the Apple Pencil—an Apple stylus. Had Apple therefore “blown it”? Well, no, because the iPad didn’t require a stylus, and it provided an answer for users who needed precision input.But it was a clear departure from the original vision,…

Compare the Top 5 PillowsHonorable MentionsThere are far too many pillows on the market. We’ve listed our favorites above, but even that doesn’t cover the wide array of serviceable designs out there for a good night’s sleep. If, somehow, all of our picks above aren’t to your tastes, here are a few others we have tested and what we thought about them.Avocado Down Pillow for $109: This down model does have feathers sourced from Responsible Down Standard (RDS)-certified farms, but it felt unimpressive and borderline flat to sleep onAvocado Green Pillow for $119: Avocado’s fill is made from GOLS-certified organic…

People take a lot of pride in their bedroom abilities. Saatva takes a lot of pride in its ability to create luxurious, handmade mattresses. To keep up the good work in both these situations, this is a bed that has many design features pertinent to lovemaking. First, you can customize the firmness level you want: Plush Soft, Luxury Firm, or Firm. I’d recommend you stick to the firmer options to avoid overt sinking, which can be a buzzkill. Height is also customizable with 11-inch and 14-inch options.The variance in firmness and height also opens up this mattress for all kinds…
