A report published in the July 8 issue of the journal Proceedings of the National Academy of Sciences (PNAS) is the first to describe the principles behind the stability and electronic properties of tiny nanoclusters of metallic gold. The study, which confirms ...

Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce more light. Research presented on July 8 at the International ...

Research at the Georgia Institute of Technology shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone....

A new assistive technology developed by engineers at the Georgia Institute of Technology could help individuals with severe disabilities lead more independent lives. The novel system allows individuals with disabilities to operate a computer, control a powered wheelchair and interact with...

Researchers have shown that a new class of ultraviolet photodiode could help meet the U.S. military’s pressing requirement for compact, reliable and cost-effective sensors to detect anthrax and other bioterrorism agents in the air. “The military is c...

A year and a half after the launch of a fleet of five satellites to probe storms in the Earth's magnetic shield, scientists have accomplished the mission's primary objective: to identify the mechanism that triggers substorms in space. Such storms ca...

Girls now equal the performance of boys on standard mathematics assessment tests, probably because girls now match boys in the number and level of math courses they take in elementary and high school, according to a new study by researchers at the Universit...

Disease-causing microbes like the food-borne bacterium Listeria monocytogenes specialize in invading and replicating inside their animal hosts' own cells, making them particularly tricky to defeat. Now, a new study led by biologists at the University of California, Berkeley, has identified a mole...

Researchers at the University of California, Berkeley, have for the first time identified environmental pollutants by looking at the genes of a small, freshwater crustacean. This new gene-based technique could lead to better and faster lab tests for pinpointing pollutants in contaminated ecosyste...
