*Discovery may lead to novel biotech and nanotech uses*

Nevada, the “Silver State,” is well-known for mining precious metals.

But scientists Dennis Bazylinski and colleagues at the University of Nevada Las Vegas (UNLV) do a different type of mining.

They sluice through every water body they can find, looking for new forms of microbial magnetism.

In a basin named Badwater on the edge of Death Valley National Park, Bazylinski and researcher Christopher Lefèvre hit pay dirt. (more…)

COLUMBUS, Ohio – Both children and the elderly have slower response times when they have to make quick decisions in some settings.

But recent research suggests that much of that slower response is a conscious choice to emphasize accuracy over speed.

In fact, healthy older people can be trained to respond faster in some decision-making tasks without hurting their accuracy – meaning their cognitive skills in this area aren’t so different from younger adults. (more…)

Tree frogs that look similar hear chromosome difference in calls; offers new insight to frog evolution

Columbia, MO – When it comes to love songs, female tree frogs are pretty picky. According to a new study from the University of Missouri, certain female tree frogs may be remarkably attuned to the songs of mates who share the same number of chromosomes as they do. The discovery offers insight into how new frog species may have evolved. (more…)
