Asterixis is a disorder in which a person loses motor control of some parts of the body. It is commonly called flapping hand tremor because the muscles in the fingers and the wrists are typically ...

Bio-inspired wind sensing using strain sensors on flexible wings could revolutionize robotic flight control strategy. Researchers at Institute of Science Tokyo have developed a method to detect wind ...

There are no powered spinning propellers in nature. When evolution has found an advantage to producing thrust in a fluid, it has done it mainly by flapping things back and forth. This new VTOL ...
