Feline researchers have long believed that purring is produced by voluntary muscle contractions, but a new report indicates that this vibration in the larynx of cats may be explained by the myoelastic aerodynamic theory of phonation.Studies on the complex action that produces a unique vibration in the larynx of cats—known as purring to most of us—have taken an important turn. It turns out that the biomechanics of the sounds emitted by domestic cats when they feel comfortable or stressed may be closer to a snore than a…

The preference change might have had something to do with the crabs’ nutrient needs changing as their metabolism speeds ramped up. If they’re generating higher pinch forces at higher temperatures, that might also expand the list of the kinds of prey they can tackle. But that may not hold true for other crab species. Other groups of animals, like zooplankton and fishes, might undergo their own subtle dietary transformations as temperatures rise.Certain species might actually benefit from rising temperatures. “Ultimately,…

Gideon Lichfield: OK, but let me play the synthetic biology devil's advocate for a second.Lauren Goode: OK, OK.Gideon Lichfield: When you have kids, you are throwing the genetic dice, you are mixing your DNA and that of your partners, and—Lauren Goode: Oh, is that how you have kids? Should we get into the birds and the bees here? You're my boss. Would you like to explain the birds and the bees to me? How does this work exactly? Gideon Lichfield: Are you being sassy?Lauren Goode: We should also probably let the audience…

Steps away from the public restrooms in Yosemite Village, a buzzy stop in Yosemite National Park’s iconic valley, sits a brown metal dumpster. Visitors reach up to open the trash chute. Their peanut butter jars and apple cores tumble into a sealed compartment. The slot slams shut. Then, they clip a tethered steel carabiner through a loop, which prevents less dextrous creatures from getting access. “USE CLIP,” reads a sticker on the chute. “SAVE A BEAR.”“Bears have evolved to be these food-finding machines,” says Heather…

Meanwhile, Hanna’s team in Israel was growing mouse embryo models in a similar way, as they described in a paper in Cell that was published shortly before the paper from Zernicka-Goetz’s group. Hanna’s models too were made solely from embryonic stem cells, some of which had been genetically coaxed to become TSCs and XEN cells. “The entire synthetic organ-filled embryo, including extra-embryonic membranes, can all be generated by starting only with naive pluripotent stem cells,” Hanna said.Hanna’s embryo models, like those…

Visolis, led by Deepak Dugar, is revolutionizing manufacturing processes to reduce greenhouse gas emissions by using microbes to ferment biomass waste, producing a carbon-negative molecular block for various items. The company has multiple products, is making millions in revenue, and is set to scale up operations, with sustainable aviation fuel being next in line for approval.Visolis, founded by Deepak Dugar, is working to decarbonize the production of everything from rubber to jet fuel.Reducing our reliance on fossil…

The new paper is the result of herculean computational analyses, involving researchers in Germany, Spain, and the United Kingdom, to better understand the role ancient retroviruses play in early embryonic development—how they harm, and how they help. It sprang from work Singh had done as a PhD student at the Max Delbrück Center in Berlin, when he gathered datasets from 11 studies to painstakingly trace individual embryonic stem cells from fertilization to implantation.He ran an analysis that grouped cells based on the…
