Athena didn’t crash. But what did happen to it? Hours after the 15-foot-tall robotic spacecraft arrived at the moon’s surface, closer to the lunar south pole than any spacecraft has been, it remained unclear whether its touchdown was smooth enough to perform its intended work, or if it toppled over in the process, potentially limiting…
On Feb. 8, Colette Delawalla, a graduate student in psychology at Emory University, nervously announced to the online world that she was planning a national protest in defense of science. “I’ve never done this before, but we gotta be the change we want to see in the world,” she wrote in a post on Bluesky,…
Postpartum depression affects about one in every seven women who give birth, but little is known about what happens in the brains of pregnant women who experience it. A new study begins to shed some light. Researchers scanned the brains of dozens of women in the weeks before and after childbirth and found that two…
Women’s brains are superior to men’s in at least in one respect — they age more slowly. And now, a group of researchers reports that they have found a gene in mice that rejuvenates female brains. Humans have the same gene. The discovery suggests a possible way to help both women and men avoid cognitive…
Humans, unlike most other species, have a knack for making tools. Six million years ago, our apelike ancestors probably smashed nuts with rocks or caught termites with sticks. Around 3.3 million years ago, hominins began using flakes of stone, perhaps to cut flesh from carcasses or chop plants. And by 1.5 million years ago, they…
For 30 miles we bounce along a dirt road in southwestern Wyoming, heading toward a jagged skyline. It’s early September and the aspens are starting to turn yellow. As we climb toward the mountains, the air grows colder. Soon the road will see snowfall. Jeff Munroe, a professor of geology at Middlebury College in Vermont,…
In May 2023, Matteo Santon was filming cuttlefish in the shallow-water reefs around Indonesia. A marine visual ecologist at Bristol University in England, he planned to document the predators’ approach to hunting from the perspective of the prey — essentially, to see what it’s like to be the crab. He was hoping to see a…
Imagine you are video chatting with a distant friend who is eating lunch, and your pal’s sandwich looks delicious. What if you could ask your friend to dip a sensor into the meal, and give you a taste? Remote snacking has moved a bit closer to virtual reality. In a paper on Friday in the…
Tea leaves pull heavy metals from water, significantly lowering the amount of lead and other dangerous compounds that people may be unknowingly drinking, a new study found. Recent research has highlighted potential applications for used tea leaves, from biofuels to gluten-free cookies. But the new study shows a public health benefit from something that countless…
The moon is not bone dry, scientists now know. But how many drops of water will thirsty astronauts find? No one knows for sure. A robotic NASA spacecraft called Lunar Trailblazer, which launched Wednesday night from Kennedy Space Center in Florida, is aiming to provide a detailed map from orbit of the abundance, distribution and…
