“We know that in nature, H5N1 viruses in birds are becoming more like viruses that affect mammals,” said Yoshihiro Kawaoka of the University of Wisconsin, Madison, co-signer of a new letter declaring an end to the research moratorium. He is also lead author of a paper examining genetic changes that can make the flu airborne. “The greater risk is not doing research that could help us to be better equipped to deal with a pandemic....
Understanding the relationship between prairie plants and fire is important for preserving this rapidly dwindling ecosystem, says Stuart Wagenius, a conservation scientist at the Chicago Botanic Garden in Glencoe and Northwestern University in Evanston, Illinois, who published the findings in Proceedings of the National Academy of Sciences. Prairies once covered vast swaths of central North America, but European settlers converted most prairies into agricultural land. Today, more than 95 percent of tallgrass prairie land has been destroyed, and fires are often suppressed in what prairie remnants remain....
“We humans, we think it’s what makes us special, what’s causing our great cooperative success,” says Désirée Brucks, the author of a new study in Current Biology and a postdoc at the University of Zurich. “But actually it’s not the case. Other species show it. Even birds, which split from mammals 300 million years ago.” This new study, performed by Brucks and coauthor Auguste M.P. von Bayernat at the Max Planck Institute for Ornithology in Germany, documented African grey parrots helping companions get a snack....
Image manipulation: GIMP If you take a lot of photos, some are bound to be pretty good. A few could be great if they were cropped correctly, with perhaps minor tweaks to their exposure or clarity. You might even want to change a photo altogether, maybe by inserting Aunt Ida into a family shot or deleting that zit that just kind of popped up. “Photoshop” may pop into your mind—as a verb even—but there is a free and open-source alternative to Adobe’s well-known program: GIMP....
Tonight at the New York Academy of Sciences, David Quammen—the author of Spillover and PopSci’s “Out of the Wild” November feature story—will probe how such diseases spill over from animals to people and why most emerging infections are viral. He’ll ask an expert panel composed of Ian Lipkin and Dan Jernigan, two of America’s top disease scientists, and Maryn McKenna, one of its top disease journalists, what the next big outbreak will look like—and what scientists are doing to try to stop it....

The paint is made from two chemicals. The first is chlorotoxin, a protein derived from scorpion venom, which targets the chloride receptors on the surface of tumor cells. The protein carries a second, non-toxic chemical that makes the cells fluoresce when they are exposed to near-infrared light. Tests at this early stage are designed to make sure that the paint works as it’s supposed to, and initial results have been promising....

My main space—a long, oddly shaped loft with towering ceilings—is far from ideal so it’s perfect for testing the limitations of virtualization. The AMBEO’s front-, side-, and up-firing speakers (13 total) do an amazing job of reflecting soundtracks (Atmos, DTS:X, or upmixed stereo) off of my architectural torture test, filling the space with kinetic audio without the multidimensional soundstage ever feeling disjointed. It’s the first soundbar in some time where my partner actually perked up only a few minutes into a Dolby Atmos-encoded film (Baby Driver, if you were wondering) and said, “OK, I can hear the difference....
Snoring is harmless, and it usually happens when your airway narrows and your tongue slides back to your throat, resulting in vibrations that can be, well, quite a nuisance to anyone you share a bed with. It’s not surprising why snoring has also earned a long list of alternative descriptions, including “sawing logs,” “mowing hay,” and “rattling the shingles.” Snoring has been a problem for so long that even folks from the past attempted to invent devices to stop it, with many of them being borderline torturous....

Researchers across the country, including at the University of California Berkeley’s Cannabis Research Center, are interested in examining how cannabis cultivation impacts the land and environment. Ariani Wartenberg, a postdoctoral fellow at UC Berkeley, is an author of a recent article that reviewed all studies that have looked at the environmental impacts of cannabis. “I was surprised, actually, at how few I found. I expected there would be more,” Wartenberg says of the studies they were able to include in the review paper....
