Zombies The Walking Dead has inspired a bit of zombie fever (and we seem to have caught it too). So, it only makes sense to have a comprehensive look at the pathology and epidemiology of zombie infections. Tara C. Smith from Kent State University surveys the rise of zombie outbeaks from the 1500s, up to the more recent incidents of “rage zombies.” Her background in epidemiology allows Smith to provide a compellingly detailed analysis for zombie nerds everywhere, though more research is needed to prevent and cure the infection....

When we can’t find what we want in the present, we go back, and back further still, until there, at the dawn of time, we imagine we’ve found it. In the gloomy mists of the past, having squeezed ourselves back into the womb of humanity, we take a good look. Here it is, we say with satisfaction. Here is the root of our difference. Once upon a time, scientists were convinced that Aboriginal Australians were further down the evolutionary ladder from other humans, perhaps closer to Neanderthals....

Since carbon dioxide tends to hog the spotlight as the climate change villain (with good reason), it might be hard to see why these regulatory changes matter. But methane is not far behind CO2 in its contribution to global warming, and slashing emissions of the gas are an important opportunity to slow rising temperatures. Here’s a little more about this molecule. Meet Methane Methane is a clear and odorless gas made up of a carbon atom and four hydrogen atoms—CH4....

The greater context here is that Zuckerberg is emphasizing that he thinks secure—and sometimes disappearing—messages (compared to the semi-public broadcasts of the posts on your newsfeed) are going to become more fundamental than ever before. Here’s what to know about the pros and cons of Facebook’s new path and what it means for your future messages. Encryption is good If you value privacy, encryption is essential. The feature means that if someone—a government, a bad actor, even the company itself delivering the message—were to intercept the note along the way, the contents would be unreadable....

Now when Facebook users update their relationship status after a breakup, they’ll be asked if they’d like to see less of their ex without having to unfriend or block them. Using this option will stop your ex’s posts from making it to your News Feed and won’t suggest their name as someone to tag in your photos. You can also limit which of your content your exes can see, and edit or untag yourself from any (or every) past post you share with them....

Critics speculate that the AquAdvantage salmon, needing as it does so much more food than a natural salmon, could extinguish the food sources in a natural salmon’s habitat. They also worry about the possibility of interbreeding. But the FDA has officially given its mark of environmental approval, thanks to certain precautions AquaBounty, the company behind the fish, has taken. The Daily Mail says, “their fish are all sterile and grown in secure containers on land-based fish farms,” which is not entirely accurate; only 95% of the fish are sterile, and given how many fish could be produced, 5% is not an insignificant number....

Beta isn’t the only company working on electric aircraft: A number of others are as well, such as Joby, Kitty Hawk, Wisk, and Archer. Those startups and others are in the process of creating planes that can take off and land vertically, like a helicopter, and then fly like typical airplanes, powered by batteries, motors, and propellers in different configurations. The industry term for these new experimental flying machines is eVTOLs, for electric vertical take-off and landing aircraft....

The idea behind PaperTab isn’t to make your iPad flexible, but to rethink the way we use tablet computers–and to make them more like the actual pieces of paper we shuffle around our desks. Designed to work in clusters of up to ten tablets, the user can control various screens at once, with one or more PaperTabs for each app in use. So you can have several documents or apps running at once and work across several PaperTabs to execute tasks while moving things around between them....

The rule was finalized on November 4 at the at the urging of Republican Governor Ron DeSantis and is set to take effect after a 21-day long public input period. The decision will not apply to transgender youth who are already receiving nonsurgical treatment. However medical professionals who violate the new rule with new patients could face severe penalties—including losing their medical license. The guidance of medical organizations including the American Academy of Pediatrics (AAP), the Endocrine Society, the United States Department of Health and Human Services, and the American Psychological Association the Florida Surgeon General’s view that gender affirming healthcare is medically unproven or potentially dangerous in the long term....

Young Marchis’ studies slewed him toward Chile, where telescopes atop arid mountainscapes capture light from distant heavens. In 1996, he trained one on Io, a moon of Jupiter, and caught something no one had ever witnessed from the ground: a ­far-off volcano belching its innards into alien air. Hooked on sharpening his view, he concentrated on developing adaptive optics—telescope sensors and mirrors that contort to make up for atmospheric turbulence that otherwise blurs images....

Throughout the pandemic, the American government had been purchasing preventative and medical care resources so that they were free to any individual. “​​The federal pre-purchasing has really ensured the availability of vaccines [and other COVID resources] for everybody who needs it, regardless of the ability to pay,” says Ali Khan, an epidemiologist and professor at University of Nebraska Medical Center’s College of Public Health. “If we disrupt that, then we should expect that vaccines may be less available or available in a more variable pattern to people across the US....

Until Heinrich Hertz discovered radio waves in 1887, the vast and invisible electromagnetic spectrum was a silent wilderness, punctuated by nature’s static bursts. But Hertz set in motion a new era that would quickly fill that void with low-end radio waves, mid-range microwaves, and high-end gamma rays (medical imaging). Despite the breadth of the wireless spectrum, a small slice (roughly 500 MHz–3.5 GHz) has been staked out like no other: As Popular Science reported in January 1978, it turns out to be the optimal range to propagate signals to and from mobile devices, like traveling telephones....

Believe it or not, there’s precedent for this sort of thing, and people involved have made out better than the snake. A pilot got sucked out of an exploded window in 1990, and was left hanging on to the crew for his life. They pulled him in a few minutes later, frostbitten but alive. As for full flights, a Romanian man clinging to the landing gear from Vienna to London (750 miles) survived though he also got frostbite....

Volunteer crews live at the station, testing habitat design features and technologies. From December 27 to January 2, six college students served as the MDRS crew, as participants in NASA’s Spaceward Bound program. Spaceward Bound is an educational program whose goal is to train the next generation of space explorers by having students and teachers participate in the exploration of scientifically interesting but remote and extreme environments on Earth as analogs for human exploration of the Moon and Mars....

But they aren’t the first animals to develop their sleek swimming technique. It turns out that plesiosaurs, marine reptiles that lived at the same time as dinosaurs (so between 200 million and 66 million years ago), used a similar method to get around in their watery environs. In a study published in PLOS Computational Biology, researchers created a computer model of how the huge reptile moved. Plesiosaurs grew to be between 8 and 46 feet long, and all had four flippers....
