Footsteps into electricty: Triboelectric generators capture world’s wasted power

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes...

An unconventional car: no engine, no transmission, no differential

This car has no engine, no transmission and no differential. It weighs half as much as a conventional car. Each of its four wheels...

Nanosensor turns pressure into light

Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale...

First human tests of new biosensor that warns when athletes are...

A new biosensor, applied to the human skin like a temporary tattoo, can alert marathoners, competitive bikers and other "extreme" athletes that they're about...

Researchers at MIT have developed an innovative approach to improving heat transfer in power plants and cooling systems. The new system could provide a...

Plants that can move inspire new adaptive structures

ANN ARBOR, Mich.---The Mimosa plant, which folds its leaves when they're touched, is inspiring a new class of adaptive structures designed to twist, bend, stiffen and even heal themselves. University of Michigan researchers are leading their developm...

A guide star lets scientists see deep into human tissue

Astronomers have a neat trick they sometimes use to compensate for the turbulence of the atmosphere that blurs images made by ground-based telescopes. They create an artificial star called a guide star and use its twinkling to compensate for the...

Nanonets give rust a boost as agent in water splitting’s hydrogen...

CHESTNUT HILL, MA (2/9/2011) -- Coating a lattice of tiny wires called Nanonets with iron oxide -- known more commonly as rust -- creates an economical and efficient platform for the process of water splitting, an emerging clean fuel scienc...

Where unconscious memories form

A small area deep in the brain called the perirhinal cortex is critical for forming unconscious conceptual memories, researchers at the UC Davis Center for Mind and Brain have found. The perirhinal cortex was thought to be involved, like the neigh...
