Upright vacuums are easy to maneuver since there’s no canister constantly bumping into furniture and walls or scuffing the floors with its wheels. They may be heavier and louder than canister models, which also feature retractable cords to prevent tripping, but as electric carpet cleaners and hardwood floor cleaners go, the best vacuums can cover a larger area and are simple to use and store. The benefits of upright vacuums don’t end there....

Instead, they are designed to let a thin layer of water in, and this water is then trapped and warmed by body heat (which is why a tight fit is important)....

And yet for as readily as we’ve adopted new storytelling platforms, our core product has always been a monthly print magazine. That’s changing. With our January 2016 issue, we will move from a monthly schedule to a bimonthly one. So instead of publishing 12 regular print issues a year, we will publish six bigger, richer ones. This is, obviously, a big change—like once every 144 years—so it bears some explanation....
Scientists tracked this bird marathon, called an “extreme endurance flight,” for nine bar-tailed godwits during the 2006 and 2007 migratory seasons. In a serious show of girl power, the female godwits flew longer and farther than the males. Seven females flew about 10,153 kilometers (about 6,309 miles) each over 9.4 days without stopping. Males logged slightly shorter distances and clocked in fewer days (they flew, at most, 6.6 days, uninterrupted)....
Bug bounties—money offered by organizations to people reporting software bugs related to security vulnerabilities—have only become more mainstream in the years since then. The pool of bounty hunters has expanded widely, and the reward for finding a bounty has quintupled for the few capable of catching the complex, valuable security vulnerabilities that companies are willing to pay millions for. But while there is a lot of money on the table, payouts tend to remain low, and chances are your average bug bounty hunter is getting paid around $250 for discovering a vulnerability....
Both fires threaten homes, businesses, and human health. (Among other dangers, wildfires can create dangerously low air quality.) But each blaze tells a bigger story. Like west coast wildfires past, they’re a smoking gun in a complex case of natural systems colliding with human folly. California has been burning since time immemorial. The golden state has two naturally-occurring “fire regimes,” says Malcolm North, a research scientist with the U.S. Forest Service and an ecologist at the University of California, Davis....
The culprit? A lithium-ion battery like the ones found in phones and laptops. While these hyperefficient cells are generally safe, they continue to store volatile energy even after they die, which means that careless disposal can cause explosions and fires. A 2021 report from the Environmental Protection Agency found public records of such conflagrations in 28 states between 2013 and 2020, and flagged one facility that had had more than a dozen in a single year....
The Y-20 is a 200 ton, 7,800km ranged four engined heavy transport with a 66ton payload. “788”, reportedly the fifth Y-20 prototype, flew in late 2015. Since then, reports suggest that the Y-20’s development has been completed and production will begin this year. Built by Xian Aircraft Corporation, the Y-20 will soon be the heaviest military transport aircraft in production (Boeing has recently closed the C-17A Globemaster factory). Eventually, China will install more powerful WS-20 turbofan engines on the Y-20 to extend its range and shorten the runway needed during takeoff....
United Launch Alliance (ULA), a joint venture of Boeing and Lockheed Martin that has long been the primary contractor for launching Defense Department payloads into space, relies on the Russian-made RD-180. ULA recently declined to bid on a launch contract due to its limited supply of rocket engines, and the Pentagon is not happy. Though ULA is developing a new engine, the BE-4 is years away from reaching the launch pad....
“For a few months now, we haven’t seen a variant that’s taken off at that speed,” Pavitra Roychoudhury, director of COVIC-19 sequencing at the University of Washington School of Medicine’s virology lab, told CNN. It is not yet clear where this version of Omicron came from, but it may have arisen in the United States. In late October 2022, it was first detected in Connecticut and New York, according to GISAID, an international effort to catalog and track COVID-19 variants....
The cone-shaped peak, which is about as tall as Mt. McKinley (the tallest mountain in North America), has shiny sides that are composed of some kind of reflective material, possibly ice. The mountain pops out of a pretty flat region, and scientists aren’t sure how it got there. Here’s a 360-degree view of the peak, from an older animation: Dawn will continue to examine Ceres in this new closeup view until December, when it’ll close in to 230 miles from Ceres’ surface, which will hopefully help to shed some light on this and other strangely shiny spots on the dwarf planet’s exterior....

Dutch researchers set up a study to figure that out. Researchers surveyed 2,000 teens in the Netherlands through their adolescence. Subjects’ were asked about their marijuana use, then asked questions designed to gauge their mental state (“Do you ever see things that others do not?”). The research team also factored in alcohol and tobacco use and a family history of mental illness. If the teens reported mental-health issues years after smoking marijuana, the researchers assumed maybe pot was the cause....
“The most recent version of the model came out in 2015 and was supposed to last until 2020—but the magnetic field is changing so rapidly that researchers have to fix the model now,” reports Alexandra Witze for Nature. The model is necessary because actually finding where magnetic north is right now is difficult—the places where it can be found are remote, and it moves a lot. Since first documented in 1831 by British Arctic and Antarctic explorer James Ross Clark, the magnetic pole has moved around a lot, vacillating between parts of Canada’s far north and Siberia....
There are a variety of theories as to why, and though it’s almost certainly in part due to a rise in awareness about the disease (and gluten-free diets generally), there’s another important potential factor that often gets misinterpreted: we’re eating more gluten. Plenty of health bloggers and pseudo-scientists will tell you that the problem, really, is all this processed wheat we eat. They’ll say something about how in Europe they’ve got wheat with much less gluten (bonus points if they tell you celiac folks can eat this gluten-deficient bread), or perhaps just stick to the argument that bread products have gotten more refined and therefore worse for us, and that’s why celiac and gluten intolerances have become such a huge deal....

FACT: NYC’s boiling hot radiators were designed to help fight a pandemic By Rachel Feltman Anyone who lives in a city is probably familiar with the radiator problem. They hiss, they rattle, they smell kinda weird when they turn on for the season, and, most importantly, they’re really hot. In a lot of cases the only options are to physically turn the radiator off at the valve, which means having no heat, or to open your window, which feels like such a waste of the gas they’re using to keep the building warm....
