Muscle power: Bats power take-off using recycled energy

Bats are uniquely able to stretch and store energy in their bicep and tricep tendons during take-off and climbing flight, giving them an extra power boost. A new study on fruitbats, to be presented at the meeting of the Society ...

Student team unveils world's first solar-powered family car

The Solar Team Eindhoven (STE) of TU/e in the Netherlands presented the world's first solar-powered family car today. 'Stella' is the first 'energy-positive car' with room for four people, a trunk, intuitive steering and ...

Researchers build robotic bat wing (w/ video)

The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among other applications. By building a robotic bat wing, Brown researchers have uncovered flight secrets of real bats: the ...

MASSIVE advances in aerodynamics

Engineers are closer to understanding, and therefore manipulating, invisible aerodynamic drag forces, that cause an estimated 50 per cent of transportation fuel to be lost before we can use it.

DARPA releases cause of hypersonic glider anomaly

(AP) -- An unmanned hypersonic glider likely aborted its 13,000 mph flight over the Pacific Ocean last summer because unexpectedly large sections of its skin peeled off, the U.S. Defense Advanced Research Projects Agency ...
