US police forces have been turning to technology to track down Black Lives Matter protesters. Content from social media platforms and affiliated sites has been instrumental in the authorities being able to identify protesters based on photos of their faces, clothes and hair, or on the fact that they posted while at the protests. Meanwhile, drones have been added to the police’s own means of capturing footage of the protests....

To stay safe while driving, you don’t have to lock away your phone completely. Modern handsets come with features that make them easier to operate in a car. First though, get some extra hardware: In many states, it’s now illegal to use a phone when driving unless you first put the device in hands-free mode and lodge it in a dock on the dashboard. Pick the right cradle for your phone and make sure to use it—as an added bonus, choose one that will charge up your phone’s battery at the same time....

Online security has never been more important, and if you think keeping all your accounts safe and secure is a big challenge, you’re definitely not alone. But even if you feel comfortable with your passwords and you’ve managed to think of a different one for every account—an impressive feat to say the least—there are simple steps you can take to lay an extra layer of protection over your data. One of the most effective is enabling two-factor authentication (2FA) across all your apps and services....

Not really, according to a new paper in the latest issue of the Proceedings of the National Academy of Sciences. In fact, profiling is no more effective than random screenings. The paper’s author, William H. Press, says that “square-root biased sampling”—a middle path between strong screening (of which racial profiling is a subcategory), and completely random screening—is a better tool for rooting out a wrongdoer. Strong screening lacks efficiency, he reports in his paper, because it wastes resources examining the same innocent people over and over every time they go the airport....

The idea of regrowing limbs sounds “kind of Star Trek-y,” Russell admits, but he says that it’s within the grasp of science. He points to his colleague at McGowan, Stephen Badylak, a pathologist and fellow AFIRM researcher, who shocked the medical world last year when he reported that a powder culled from pig bladders helped resprout the severed fingertips of two patients in their 60s. Normally, when a person loses a limb, scar tissue forms over the wound, leaving a permanent stub....

FN Meka isn’t “real,” in so much that he is a sentient person He’s an AI-generated rap avatar created by Anthony Martini and Brandon Le back in 2019 that relies on proprietary music technology from an industry development company called Vydia to generate beats, melodies, and even lyrics “created using thousands of data points compiled from video games and social media” that are subsequently rapped by anonymous human for actual songs....

This is how the levitation works. Inert, magnetic nanoparticles are inserted into the cells, and researchers can manipulate them by using magnets–in this case, a magnetic “pen.” That ability to tinker with the cells opens the door for more complicated cultures. The four-layered replication, of the lung’s bronchiole tissue, is made from endothelial cells, smooth muscle cells, fibroblasts, and epithelial cells. Arranging those cells in the same way as lung tissue has never been done before, and the researchers say it’s the closest anyone’s gotten to real bronchiole tissue....

Despite the Galaxy name, both machines run a full Windows operating system and rely on dedicated laptop processors rather than trying to max out mobile chips to save space and weight. That puts Samsung’s new machines in direct competition with Apple’s excellent M1-powered MacBooks. Here’s an overview of Samsung’s new Galaxy Book Pro models. Galaxy Book Pro Laptop Starting at $999, the Galaxy Book Pro utilizes a standard clamshell laptop design....

But what’s a cat parent to do if their precious kitty refuses to drink? Here’s a little secret: cats tend to shy away from still water from a regular dish and tend to gravitate more towards flowing water. To keep your cat hydrated and healthy, investing in a cat-friendly water fountain like KittySpring is the smartest option. Get a KittySpring Water Fountain For Cats for just $33.15 (reg. $39) with code JAN15 during our January Sale....

Last week, researchers at the National Tropical Botanical Garden on the island Kaua’i announced they’d discovered a few thriving members of Hibiscadelphus woodii, officially (and now it seems mistakenly) declared extinct in 2016. The plants—which grow in Kalalau Valley, by all accounts Hawaii’s equivalent of the Cliffs of Insanity—were found not by foot, but by drone. The flower, seen above before its brilliant yellow flowers go wine-darken with age, was formally discovered in 1991 by Ken Wood, a conservation biologist who specializes in the plant life of the Pacific islands....

So you can install Ubuntu on most Android devices–it’s not an Android skin, it’s a completely new OS, but since it’s built on Linux, the same way Android is, Canonical says it’ll be no problem to install on modern Android phones. They’ve been demonstrating it on a Galaxy Nexus. There may be native Ubuntu hardware in 2014, but nothing’s been announced, so let’s treat this as an alternate OS for Android devices for now....

Jonny Williams squeezes into a soaped-up wetsuit near the base of British Columbia’s Tantalus Range, a series of 2,000-plus-meter peaks that give rise to the region’s moniker, Sea to Sky. The water he slips into is like glass, an unexpected gift in a glacier-etched fjord known to funnel high winds. As he kicks his fins along the shoreline, jets of seawater sparkle as they meet the sun. A while later he bobs back up and yells, “I almost smoked my head!...

The researchers were making hydrogels, a matrix of gelatinous fibers that can support living cells and replace any number of tissues in the body, especially muscle tissue like those in the heart. Hydrogels are about as close as researchers can currently get to emulating human tissues because the moist fibers that make up the hydrogel allow oxygen and nutrients to flow to and from the living cells. To create these gels, researchers spin polymer fibers together into a mass using a process called electrospinning....

So what could possibly stop these sturdy little creatures? Turns out it’s being shot out of a two-stage light gas gun toward sand targets in a nylon bullet, according to a new study published in Astrobiology. But there’s a reason for shooting microscopic organisms at high speeds: understanding the limits of extraterrestrial life. Researchers like Alejandra Traspas, a PhD student at Queen Mary University of London who led the experiment, and her supervisor Mark Burchell, a professor of space science at the University of Kent in England, must systematically work through the obstacles that any living organism would have to overcome to survive....

AstraZeneca’s clinical trials last year and its subsequent vaccine rollout earlier this year were clouded by rare, but sometimes deadly, blood clots. After one participant in the clinical trials experienced neurological symptoms, countries around the world put their AstraZeneca trials on pause. Then, when two Austrians experienced blood clotting after vaccination, the European Union temporarily suspended the use of the vaccine. Although the vaccine is now widely used around the world, including in Canada, India, and throughout Europe, the United States has not approved it....

Researchers from the University of Queensland’s School of Biological Science have devised a way to study sea turtle diets in the wild, while they’re still alive. Owen Coffee, a PhD student, is studying the turtles’ eating habits to determine where they’re foraging, to better protect those areas. To do so, they made sea turtle swimsuits. The swimsuits are perhaps a bit closer to full-body diapers, as they are designed especially to capture the turtle’s fecal matter in the open ocean—not an easy task....

Here are a few of the most practical and effective ways to jumpstart your sustainable New Year’s resolutions. Eat locally and consciously Being more conscious about what we eat is a straightforward way to jumpstart personal climate goals. Food waste is a massive problem across the world, not only because of the ethical implications of perfectly good meals hitting the landfill instead of someone’s plate, but also because of the carbon footprint and pollution impacts of that trash....
