Trace metal recombination centers kill LED efficiency

Using cutting-edge first-principles calculations, researchers at the University of California, Santa Barbara (UCSB) have demonstrated the mechanism by which transition metal impurities - iron in particular - can act as nonradiative ...

Scientists set traps for atoms with single-particle precision

Atoms, photons, and other quantum particles are often capricious and finicky by nature; very rarely at a standstill, they often collide with others of their kind. But if such particles can be individually corralled and controlled ...

EPA proposes expanded use of new herbicide, Enlist Duo

The Environmental Protection Agency has proposed more than doubling the number of states allowed to use a new version of a popular weed killer on genetically modified crops despite its earlier concerns.

Mussel power: Researches develop underwater glue

Even the strongest glues collapse when soaked. Just watch a band-aid slide ungracefully off a finger or toe while in the shower. However, with support from the Office of Naval Research (ONR), one researcher has developed ...

WikiLeaks founder denies Russia behind Podesta email hacking

WikiLeaks founder Julian Assange denied Thursday that the Russian government or any other "state parties" were his group's source for more than 50,000 hacked emails from the files of Hillary Clinton's campaign chairman, John ...

Study links human actions to specific Arctic sea ice melt

Driving a gas-powered car about 90 miles—the distance between New York and Philadelphia—melts about a square foot of Arctic sea ice in the critical month of September, according to a new study that directly links carbon ...

Gene regulation: Shaping up to make the cut

Before RNA copies of genes can program the synthesis of proteins, the non-coding regions are removed by the spliceosome. Munich researchers report that distinct conformations of a member of this molecular complex play a vital ...
