Researchers show it's possible to teach old magnetic cilia new tricks Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed. Scottish leader faces battle for survival after ending power-sharing deal over climate change clash Scottish leader Humza Yousaf's decision Thursday to end a power-sharing agreement with the Scottish Green Party has triggered events that could see him lose his job next week.

29 Pilot Whales Die After Mass Stranding on Australian Beach Of the 160 whales stranded near the town of Dunsborough on Thursday morning, more than 100 were saved and returned to the ocean. Study finds genetic basis for link between depression, heart disease A group of genes could be common to both depression and heart disease, a finding that researchers said could explain why having one of them increases risk of developing the other. The "puzzling" link between the diseases has been known to exist since the 1990s, they said. Studies have found that people with depression run a greater risk of cardiovascular disease, with early and effective treatmen… Rocket Lab to launch NASA, Korean payloads on Electron flight NASA’s Advanced Composite Solar Sail System (ACS3) will test materials and a deployable system for a solar sail-style propulsion system. Liftoff from New Zealand is set for 10:00 a.m. NZT on April 24 (6:00 p.m. EDT, 2200 UTC on April 23). |
