| Elephants strive to cooperate with allies, until the stakes get too high Posted: 28 Sep 2021 11:18 AM PDT Asian elephants are keen to cooperate with friends and have evolved strategies to mitigate competition in their social groups, but cooperation breaks down when food resources are limited, according to new research. The study sheds light on the evolution of cooperative behavior in mammals. |
| Microscopic metavehicles powered by nothing but light Posted: 28 Sep 2021 04:50 AM PDT Researchers have succeeded in creating tiny vehicles powered by nothing but light. By layering an optical metasurface onto a microscopic particle, and then using a light source to control it, they succeeded in moving the tiny vehicles in a variety of complex and precise ways -- and even using them to transport other objects. |
| Peering into the Moon's shadows with AI Posted: 23 Sep 2021 08:56 AM PDT Permanently shadowed lunar craters contain water ice, but are difficult to image. A machine learning algorithm now provides sharper images. |
| Llama antibodies have 'significant potential' as potent COVID-19 treatment Posted: 22 Sep 2021 06:08 AM PDT A unique type of tiny antibody produced by llamas could provide a new frontline treatment against COVID-19 that can be taken by patients as a simple nasal spray. |
