Bits of a protein that builds up in Parkinson’s disease trigger the immune system, causing it to tag them as foreign invaders. In a blood test, immune cells called T cells became activated when exposed to the protein in about 40 percent of Parkinson’s patients in a new study. This autoimmune response may contribute to […]
The Great American Eclipse on August 21 will be much more than a spectacle. As the moon passes in front of the sun, scientists will be doing some serious work. A fleet of telescopes, spectrometers and polarizers will turn skyward to look directly at the parts of our nearest star that are usually invisible. But […]
Nighttime may be snow-time on Mars. Low evening temperatures could cool clouds and trigger turbulent winds that fuel fast-falling snowstorms on the Red Planet, new simulations suggest. This process, reported August 21 in Nature Geoscience, may account for surprising observations of snowfall by one of NASA’s Martian landers. “Clouds and snowfall have emerged in recent […]

And her dreams are so big, they may one day save your mind.Sarkar is a nanotechnologist and assistant professor at MIT. She develops ultratiny electronic devices, some smaller than a […]
Brains are like sponges, slurping up new information. But sponges may also be a little bit like brains. Sponges, which are humans’ very distant evolutionary relatives, don’t have nervous systems. But a detailed analysis of sponge cells turns up what might just be an echo of our own brains: cells called neuroids that crawl around […]
Regenerating body parts is never easy. For instance, some lizards can grow back their tails, but these new appendages are pale imitations of the original. Now, genetically modified stem cells are helping geckos grow back better tails. Tweaking and implanting embryonic stem cells on the tail stumps of mourning geckos (Lepidodactylus lugubris) allowed the reptiles […]
Olympic gold-medal winning gymnast Suni Lee said she was the victim of a racist attack in October. Lee told PopSugar that when she was out with friends in Los Angeles one night, a group speeding by in a car yelled racial slurs and that one passenger in the car sprayed her in the arm with […]
