Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor

When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties.

Biofuels boom could fuel rainforest destruction

Farmers across the tropics might raze forests to plant biofuel crops, according to new research by Holly Gibbs, a postdoctoral researcher at Stanford's Woods Institute for the Environment.

Gov. researchers highlight potential for improved solar cells

A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication—when a photon creates multiple electrons—is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication.

Termite insecticide a potent greenhouse gas

An insecticide used to fumigate termite-infested buildings is a strong greenhouse gas that lives in the atmosphere nearly 10 times longer than previously thought.

And then there were three

I just don't get those guys anymore.... (Photo by Lori Eggert, UCSD) You learn a lot analyzing dung. Sampling specimens from wild African elephants, UC San Diego researchers have found the continent is home to three distinct types of Proboscidia, not two. Apparently the distinction in the past was between savanna and forest elephants. Now it turns out a third, genetically distinct species has evolved that swings both ways.
