In his new book, Candid Creatures: How Camera Traps Reveal the Mysteries of Nature, out this month, Roland Kays takes us inside the world of camera traps, compiling over 600 photographs from camera traps set up by individuals and research groups around the world. Kays, as the director of the Biodiversity Laboratory at the North Carolina Museum of Natural Sciences, knows how important camera traps are for researchers trying to keep track of elusive wildlife populations....

For some people, it can be really hard to choose which one is the best for them because there are so many options out on the market today. That’s why we put together this list of the 12 best testosterone supplements on the market today. You don’t have to try out all 12. You can simply pick one that you think would work for you or just buy them all to see which one works the best....

Now, two new study preprints, neither yet peer-reviewed, suggest that last year’s drop in flu cases could lead to a high resurgence of flu this season due to lower immunity against influenza across communities. A 25 to 50 percent increase in flu vaccinations this year, one study says, could prevent that upswing. Last year was a record low for the flu. The US Centers for Disease Control and Prevention (CDC) report that the 2020-2021 flu season yielded just one child death by the flu—an incredible dip from the previous low of 37 (during the 2011-2012 season) and the 2019-2020 record high of 199....

Now you’ll be able to buy your BRCA test online and get your results a few months later, all without ever seeing a genetic counselor or doctor. In some ways, this is a wonderful advent of technology. It democratizes health information. It empowers people to take control of their lives and mitigate risks. But it also means we’re handing out data to people who might not be adequately prepared to hear it, and who might not actually understand what they’re getting....

Thinking decades ahead, the Navy has big plans for 3-D printing, like making human tissue on demand for medical emergencies, or custom-printing drones and missiles as a mission requires. For now, though, the printer is solving much simpler tasks, like lost caps and awkward funnels. From the Virginia Pilot Parts are designed with computers in the fabrication station, and printed to order right on board. It’s a pretty great solution to an ancient sailor’s problem....

The researchers found the hearts, which likely belonged to wealthy noblemen, when they were excavating the ruins of the Convent of the Jacobins in Rennes, France. Since the excavation began in 2011, they have found some 800 graves, along with these five embalmed hearts, each encased in heart-shaped urns made of lead. Slowly and carefully, a team of experts in many different disciplines removed the hearts from their urns and unwrapped the embalming material....

After high school, my education and career led me away from science. But since becoming a parent, I’ve been looking for ways to recapture that youthful passion, and pass it onto my children. Citizen science is an opportunity to do both. What is citizen science? Scientists are constantly struggling to fund their research, and when resources are scarce, scientific advancement can stall. Citizen science is a way to prevent that, engaging regular people to gather, review, and analyze scientific data on everything from wildlife to weather to public health to interstellar phenomena....

I guess I’m not alone, because Steelcase just developed a chair meant for the questionable posture practiced in meeting rooms. After taking a test-sit, I can say that the Cobi, coming out in February for $635, will support you just fine if you sit up with a straight back and feet on the floor. But it holds you well in just about any other position, too. The glass-reinforced nylon back if the chair is composed of horizontal bars that Steelcase calls “fingers....

But as my kids have begun first grade and their first in-person schooling experience, I want them to have something healthier and more filling. After all, studies suggest that bad nutrition and hunger are connected to poor grades and decreased cognitive performance. And for parents it’s not only a matter of caring—research shows that despite our best intentions, many packed lunches don’t have as many essential nutrients as those provided by the National School Lunch program....

Those were the words that Richard Nixon read on television in 1969 while breaking the terrible news to the nation that the Apollo 11 mission had failed and astronauts Neil Armstrong and Buzz Aldrin had perished while attempting the first lunar landing. But only in an alternate reality. Nixon never had to utter those lines because Apollo 11 was a historic success, and Armstrong, Aldrin, and their pilot Michael Collins made it safely back to Earth....

Problems arose when the crew began preparations for the eventual installation of a brand new advanced toilet system, the Universal Waste Management System, designed to handle astronaut waste and disposal more efficiently. The UWMS is supposed to be 75 percent more compact than previous toilet system used on the ISS and the Space Shuttle, and improve cleanliness as well. Unfortunately, installing a new toilet is space is as messy as it is here on Earth....

“Both American beavers and gray wolves are native to most of the western US and a keystone species,” says William Ripple, an ecologist at Oregon State University. Keystone species are defined as wildlife that have a dramatic effect on their ecosystems, despite low abundance. Ripple is one of the authors of a study published on August 9 in the journal BioScience. He and his collaborators identify 500,000 acres of federal public land that would provide ample space for reintroducing wolves and beavers, and outline a three-step plan to bring back the two species to their historical habitat....

Unlike other portable power sources, which store energy in batteries, the Nectar runs on butane. When a user plugs his phone into the Nectar’s USB port, a replaceable butane cartridge releases fuel into the cell. As fuel passes over a ceramic membrane, oxygen ions pass through the surface, which generates a current. The process can run as hot as 1,830°F, so the engineers built a network of insulating silicon-nitride tubes to keep the Nectar’s exterior cool....

One morning in August 2018, a man named Ralph Breeden telephoned the Florida Fish and Wildlife Conservation Commission to report that a dead manatee was bobbing in the bay behind his house in a quiet Sarasota suburb. Soon, two biologists, Gretchen Lovewell and Rebeccah Hazelkorn, were on their way to recover the corpse in a pickup truck fitted with a portable crane. Lovewell and Hazelkorn are the equivalent of marine EMTs and coroners, performing rescues and necropsies, operations that often require them to handle turtles that weigh more than 200 pounds and dolphins over 6 feet long....

The transparent patch is made of a specially developed polymer matrix, which is sticky enough to adhere to skin despite its high drug content (up to 30 percent of the patch’s weight). For up to 12 hours, the patch can deliver a high dose of the painkiller at a steady rate directly to the area that needs it. The ability to take ibuprofen this way could help those treating chronic conditions like back pain or arthritis, without risking the adverses heart and stroke side effects that come with high oral dosages....
