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 ...

At this point, building a flying vehicle isn’t terribly hard. Aviation enthusiasts can buy DIY kits and build themselves a plane that can easily and safely take to the skies. But a flying vehicle that ...

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and ...

Flap your arms for a while and you’ll soon notice that the constant cycle of acceleration and deceleration requires and even wastes huge amounts of energy. And yet for birds, wing flapping is a highly ...

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 ...

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 was a time when I considered Andrew’s arm flapping to be a maladaptive behavior; a piece of the autism puzzle that needed to be solved and put in its place. I worried that those wild flailing ...
