Choose a lens shape: Cylindrical lenses look flat and are curved around the face on the vertical axis. These are cheaper to manufacture than spherical lenses, and when used on a large pair of goggles can offer a vast field of view. Spherical lenses are curved both vertically and horizontally and give the goggles a bug-eyed look. Spherical lenses help to open up more of the view, especially the up and down aspects. You’ll pay more for spherical lenses, but they can be truly impressive.From an aesthetic point of view, cylindrical lenses are more popular, but the latest (and most…

A federal judge on Monday declined to immediately curb the federal operation that has put armed agents on the streets of Minneapolis and St. Paul, but ordered the government to file a new briefing by Wednesday evening answering a central claim in the case: that the surge is being used to punish Minnesota and force state and local authorities to change their laws and cooperate with the targeting of local immigrants.The order leaves the operation’s scope and tactics in place for now, but requires the federal government to explain whether it is using armed raids and street arrests to pressure…

Apple’s AirTag has become the de facto “Bluetooth tracker” since its 2021 debut, upending established players like Tile. Now, Apple is finally upgrading the hardware. The second-generation AirTag still costs $29 for one, and $99 for a four-pack, and it’s available today.It’s powered by the second-generation Ultra Wideband chip (U2), which Apple has already employed in recent iPhone and Apple Watch models. It improves the ability to find the tag’s exact location when using Apple’s Precision Finding mode, with up to 1.5 times greater range. You can lift your iPhone, and you’ll receive visual, audio, and haptic feedback as the…

With the marshals under attack, Kennedy deployed first the Mississippi National Guard and then thousands of federal troops as well. (That military operation, codenamed RAPID ROAD, was actually the first and only time during the Cold War that the military activated and used plans it had developed to quell civil disturbances in the wake of a nuclear attack.)Then, in 1963, Kennedy again relied on the National Guard to help with the integration of the University of Alabama, and his successor, Lyndon Johnson, used marshals and the National Guard to protect civil rights marchers in Selma after Alabama state troopers infamously…

They intuited that molecules near the surface behave differently from those deep within the ice. Ice is a crystal, which means each water molecule is locked into a periodic lattice. However, at the surface, the water molecules have fewer neighbors to bond with and therefore have more freedom of movement than in solid ice. In that so-called premelted layer, molecules are easily displaced by a skate, a ski or a shoe.Today, scientists generally agree that the premelted layer exists, at least close to the melting point, but they disagree on its role in ice’s slipperiness.A few years ago, Luis MacDowell,…

Within minutes of Alex Pretti being shot and killed by a federal immigration officer in Minneapolis on Saturday, the Trump administration, backed by right-wing influencers, launched a smear campaign against the victim, labeling him a “terrorist” and a “lunatic.”Pretti, 37, was killed during a confrontation with multiple federal immigration agents. Pretti was an American citizen and a registered nurse who worked in the Department of Veterans Affairs, according to a colleague who spoke to the Guardian. Video from a bystander shows Pretti was attempting to help a woman who had been pepper sprayed by an immigration agent when officers tackled…

Best Grind-and-Dry Food RecyclerLomi3 Countertop Food RecyclerMost kitchen “composters” simply grind and dry your food scraps, but the Lomi 3 does the best job of this of the bunch. I’m always impressed when companies listen to feedback and adapt, and Lomi’s new model solves a couple of the now-discontinued Lomi 2’s quirks and foibles. Gone are the multiple modes, annoying twist-off lid, and having to put scraps right into the machine. Now there’s a convenient 3-liter, 7.5-inch-tall countertop bucket, just like the FoodCycler below; an easy push-button lid; and just two simple processing modes: Grow and Express. The Lomi 3…

Here it comes. Up to two thirds of the US is facing down the threat of serious snow, cold, and ice this weekend, with the potential to snarl roads (and the businesses that depend on them) from Texas up to New York City. At this point, grocery stores, logistics experts, warehouse operators, and trucking companies have been prepping for days. Still, the effects on the supply chain—and the retail store shelves that depend on them—are yet to be determined.On one hand, this is winter business as usual. Snowstorms happen every year, and the freight industry has a playbook.“If you’re a…

Is there such a thing as the best notebook? Probably not. Notebooks are not a one-size-fits-all commodity. If none of these quite tilt your pen, here are some general things to look for in a paper notebook.Paper quality: High-quality paper will improve your writing experience. That said, what constitutes high-quality paper depends a lot on your writing device. For example, heavy ink pens, like fountain pens, will require thicker paper to avoid ghosting (when the ink soaks through), while coarser paper might be better for sketching with a soft pencil. (Much of this depends on personal preference too.) If you’re…

As this year’s Oscar nominations rolled out this morning, I told my boyfriend that Sinners, with 16 noms in total, had made history. “Woke is back,” he replied.He was joking (don’t come for him!), but his quip highlights a pretty stark dichotomy. Last year, as everyone from President Donald Trump down harped on about the perils of DEI, the biggest cultural breakthroughs—Sinners, KPop Demon Hunters, Heated Rivalry, One Battle After Another—all showcased diversity in fresh ways. And it succeeded. These works weren’t just popular among leftists or critics, they were bona fide cultural phenomena.Sinners, a horror movie set in the…
