Modeling the aerodynamic secrets of one of Nature's most efficient flyers Researchers are one step closer to creating a micro-aircraft that flies with the maneuverability and energy efficiency of an insect after decoding the aerodynamic secrets of insect flight. Dr John Young, from the University of New South Wales (UNSW) in Australia, and a team of animal flight researchers from Oxford University's Department of Zoology, used high-speed digital video cameras to film locusts in action in a...

A U.S. study shows not all insects have rigid wings, with some insects, such as moths, having wings that flex and deform during flight. University of Washington researchers said most scientists who study the mechanics and aerodynamics of insect flight have assumed insect wings are relatively rigid as they flap. But the researchers in the new study, led by biology Professor Thomas Daniel, used high-speed digital imaging to show some insects' wings flex and deform while in flight. The evidence...

Most scientists who create models trying to understand the mechanics and aerodynamics of insect flight have assumed that insect wings are relatively rigid as they flap.New University of Washington research using high-speed digital imaging shows that, at least for some insects, wings that flex and deform, something like what happens to a heavy beach towel when you snap it to get rid of the sand, are the best for staying aloft."The evidence indicates that flexible wings are producing profoundly...

CORVALLIS, Ore. "“ Humans with an appreciation of beauty may have marveled for millennia at the artistry of a darting hummingbird, but scientists announced today that for the first time they can more fully explain how a hummingbird can hover. Using a powerful technology that was originally developed for engineering, researchers were able to exactly document the movement of air around a hummingbird's wings and show how its flight is accomplished with the body structure of a bird but some...

WASHINGTON (Reuters) -- Hummingbirds hover by flapping their wings a bit like insects and a bit like other birds, and now a super-fast camera has made an image of the technique, scientists reported on Wednesday. A team of U.S. researchers found that hummingbirds manage to hover in air for long periods by supporting 75 percent of their weight during their wings' down stroke and 25 percent on the up stroke. Other birds support all of their weight on the down stroke for slow flight and...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
