According to a new report from AccuWeather, the 2021 tornado season, which stuck around until December, will be followed up by another “turbulent” year. 2022 got off to an ominous start with several storms ripping through central Alabama and central and southern Iowa in February and early March. The counts are only expected to ramp up over the next few months. “This is the worst anyone has seen in a very long time,” Diogenes Ayala, the Emergency Management Director of Madison County, Iowa, told the Associated Press after seven locals were killed by a rash of tornadoes....

But it’s also a significant contributor to the climate crisis, notably through agriculture. About a third of the N2O released in the atmosphere comes from human activity, which can largely be traced back to the use of synthetic fertilizers in agriculture that boost the amount of nitrogen in the soil for higher crop yields. The accurate amount of N2O emitted has been hard to quantify because of spatial and temporal variability....

To do this, soldiers from the Army’s 43rd Air Defense Artillery Regiment used two Patriot and Sentinel radars, Patriot missile launchers, and Patriot interceptors, all coordinated through a new command system. This connective tissue between sensors and interceptors is the Integrated Air and Missile Defense Battle Command System, or IBCS. It’s a way for the Army to coordinate radars and missile interceptors across a broad area, comprehensively detecting incoming threats and then making sure those missiles are stopped, without overcommitting interceptors and depleting vital stockpiles....

A different way to organize your windows Stage Manager is a new feature for both macOS and iPadOS that changes how you manage your open windows: It displays thumbnails of all open programs in a column down the left side of the screen, making them easier to switch between. As always, there are some major upgrades you should check out first. To enable it, open Control Center from the menu bar and click Stage Manager....

There has been a recent nostalgia-fueled resurgence in calculator watch popularity, with the iconic Casio still dominating the landscape. Here are some of the best options from that brand, as well as a couple of other contenders. The granddaddy of calculator watches still beats all newcomers. The Casio DBC150-1AES is capable of handling whatever you throw at it, and the blue-tone face rounds out its all-around retro feel. It has a calendar function that allows you to keep track of important dates and appointments, as well as a massive 150-page data bank....

Now astrophysicists have used another extreme machine to discover a natural electron bazooka that makes SLAC look like a pea shooter. Over the last year or so, a colossal facility high in the mountains of southwest China picked up two showers of particles each produced by a single high-energy beam of light—a gamma ray—slamming into the upper atmosphere. Both gamma rays appear to have originated from the Crab Nebula, a sign that the famous supernova remnant harbors the most powerful electron accelerator yet identified....

It’s a rare day when all six of these companies can agree on something, but that day seems to have arrived, thanks to the U.S. Federal Bureau of Investigation. Google first showed tepid support for Apple in this fight last week, when CEO Sundar Pichai tweeted that “forcing companies to enable hacking could compromise users’ privacy.” Then it seemed like Microsoft might be siding with the FBI, when co-founder and former CEO Bill Gates gave an interview to the The Financial Times earlier this week saying that the FBI was only looking for Apple’s help in this specific case....

But you may be wondering what prompted such a sweeping and troubling recall—as well you should. Here are a few things to know about what went wrong with Herbal Doctor Remedies, as well as what this incident can teach you about supplements in general. Why the recall? The FDA hasn’t cited any specific manufacturing problems, but reports that Herbal Doctor Remedies failed to follow Current Good Manufacturing Practices (CGMPs). The FDA doesn’t have oversight over dietary supplements in the same way it does actual drugs, but the CGMPs exist to ensure that products contain what their packaging claims they contain and in the right quantities....

Fleye breaks the typical drone mold, a white quadcopter with little legs, and instead opted for a floating sphere. Up close, the drone looks like a well-designed oscillating fan that’s been turned sideways. Oh, and for the pleasure of piloting a volleyball, you have to cough up a hefty $1200. Despite its shape, the Fleye handles shockingly well, and it’s totally safe because all the blades are enclosed inside the styrofoam casing....

That’s an old story, but 84 years after Parker’s and Barrow’s deaths, car chases remain common: In 2012 alone, police in the United States racked up 68,000 pursuits, according to the latest data from the Bureau of Justice Statistics. Half of these chases started with a simple traffic stop—a broken taillight, failure to signal. But then, for various reasons, these drivers presumably had reasons to rabbit, from outstanding warrants to smoldering joints to illegal weapons....

It used to be that quality studio gear was out of the reach for musicians recording at home. In 2022, a home studio is a big investment, but you can set up a decent studio for less than $2,000 rather than, say, $20,000. “Perfect” is personal. It’s about your space, your budget, and, most importantly, your creative vision. Start small with your first home recording studio When you’re starting from scratch, less is more....

Just when you thought you could no longer take the barrage of bad undies, PopSci comes in with the list of higher-grade intimates that you’d actually want to get intimate with. Whether you’re working out five days a week, trying to save the earth, or just feel like being in your skivvies, our guide to briefs, bikinis, and boxers will have you putting underwear on your wishlist for years to come....

The Hexo+ uses an iOS or Android app to pair via Bluetooth and follows whoever is carrying the smartphone with the app installed. The drone reaches a top speed of 40 miles per hour and offers options for following close and far. An even closer option is currently in beta. What sets Hexo’s drone from the camera-touting competition is the mechanical stabilization technology used. Much like optical image stabilization in many cameras, the camera rig physically moves to account for any shaking the drone does mid-flight....

But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements. Decades before, chemist John Dalton tried to create a table as well as some rather interesting symbols for the elements (they didn’t catch on). And just a few years before Mendeleev sat down with his deck of homemade cards, John Newlands also created a table sorting the elements by their properties. Mendeleev’s genius was in what he left out of his table....

In most concrete bridges, beams stretch between columns to support the roadway above and are made from poured concrete with steel rebar inside. But thousands of beams will soon need to be replaced as bridges are repaired and upgraded in the wake of the Minneapolis bridge collapse last summer. According to the Federal Highway Administration’s 2007 National Bridge Inventory, one in four bridges is either structurally inadequate or no longer meets current standards....

“The IRS takes taxpayer privacy and security seriously, and we understand the concerns that have been raised,” said IRS Commissioner Chuck Rettig in an online statement. “Everyone should feel comfortable with how their personal information is secured, and we are quickly pursuing short-term options that do not involve facial recognition.” In November, the IRS announced it planned to transition to a new identity verification system using an outside company called ID....

To do this research, the authors took the gene for Omicron’s spike protein, which is what the virus uses to enter cells in the body, and added this spike protein gene to the genome of what’s called a backbone virus. This hybrid virus is based on an original COVID variant that was identified in Washington state soon after the pandemic first emerged in 2020. The main focus of the research was to see if the spike protein in Omicron causes less severe disease, with the hope that better COVID-19 diagnostic tests and treatments could be developed....

Longhorned ticks weren’t previously known to live in the U.S., much less to live on a solitary sheep in Hunterdon, New Jersey that had never traveled outside of the country. She hadn’t even left the property in years. Yet here was a bug that wasn’t supposed to exist on this continent—in droves. After the sheep’s owner brought some tick samples to the CDC back in August 2017, the agency started digging a little deeper....

The first half of this week has been unprecedentedly hot in the Northwest region of the US and western Canada—this is the most intense heatwave to ever hit the region. After an already scorching and record-breaking weekend, with temperatures as high as 112 degrees Fahrenheit in Portland and 108 in Seattle, thermometers crept even higher Monday and Tuesday, sometimes exceeding 30 degrees above the normal daily temperature. Thankfully, most of the heat had passed by Wednesday, as temperatures settle towards the weekend....
