| Seeing a fluid behaving like a solid Posted: 14 Aug 2020 10:10 AM PDT Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a solid-like response to stress, a phenomenon called Discontinuous Shear Thickening (DST). This is when liquid abruptly thickens and becomes solid when disturbed. DST is being researched for engineering applications such as soft body armor, 'smart' speed bumps, and food production. |
| Aurora mysteries unlocked with NASA's THEMIS mission Posted: 14 Aug 2020 10:10 AM PDT A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space. |
| Meditation-relaxation therapy may offer escape from the terror of sleep paralysis Posted: 12 Aug 2020 06:49 AM PDT Sleep paralysis -- a condition thought to explain a number of mysterious experiences including alleged cases of alien abduction and demonic night-time visits -- could be treated using a technique of meditation-relaxation, suggests a pilot study published today. |
