Researchers squeeze more electricity from heat
Researchers at Ohio State University have invented a new material that can generate electricity from heat in hot machine environments at an unprecedented rate. The new material is called thallium-doped lead telluride. The development could have a dir...
Carbon nanotubes combine high performance and flexibility for electronics.
New research suggests that networks of single-walled carbon nanotubes printed onto bendable plastic perform well as semiconductors in integrated circuits. Researchers from the University of Illinois at Urbana-Champaign (UIUC) and Purdue University, w...

Ed Begley, Bill Nye wage friendly eco war
On a tree-lined corner of Studio City filled with modest homes, flower gardens and neighbors who chat across back fences, two wiry celebrities are engaged in a green grudge match. The good-natured competition between actor Ed Begley Jr. and Bill Nye,...
Researchers have controlled the position of a single electron in a silicon circuit.
An international team of researchers has shown that it can control the quantum state of a single electron in a silicon transistor--even putting the electron in two places at once. Their discovery could help pave the way toward a practical quantum com...
Stereo Mammograms detect cancer better
Mammograms are one thing that if you bring it up in a room full of women, you’re bound to here a bit of grumbling. They are uncomfortable and apparently not always that accurate. Well now there is a new method in the works that is more accurate and o...
