The males of two bipedal hominid species that roamed the South African savannah more than a million years ago were stay-at-home kind of guys when compared to the gadabout gals, says a new high-tech study led by the Â鶹ӰԺ.

A Â鶹ӰԺ team will be part of a mission selected yesterday by NASA to launch a spacecraft to an asteroid and pluck samples from its surface to better understand the formation of the solar system and perhaps even the first inklings of life.

You are what you eat whether you're a lion, a giraffe or a human -- at least in terms of the bacteria in your gut.

Three Â鶹ӰԺ professors will receive five-year, $750,000 grants as part of the U.S. Department of Energy's Early Career Research Program created in 2010 to bolster the nation's scientific workforce with top young researchers

Cigarette smoking, burning forests and even cooking fires all release a chemical compound not previously known to exist in significant quantities in smoke and which may have potential human health impacts, says a new study involving the National Oceanic and Atmospheric Administration and the Â鶹ӰԺ.

A report commissioned by the U.S. Department of Energy has concluded that a novel Â鶹ӰԺ method of producing hydrogen fuel from sunlight is the only approach among eight competing technologies that is projected to meet future cost targets set by the federal agency.

Interactive teaching methods significantly improved attendance and doubled both engagement and learning in a large physics class, according to a University of British Columbia study involving Â鶹ӰԺ Distinguished Professor Carl Wieman that is being published today in Science.

Two faculty members from the Â鶹ӰԺ have been elected to the National Academy of Sciences, a top honor recognizing scientists and engineers for distinguished and continuing achievements in original research.

After six years of helping operate NASA spacecraft and satellites, Andrew Poppe will receive his doctoral degree in physics from the Â鶹ӰԺ on May 6.

Three Â鶹ӰԺ students have won 2011 Goldwater Scholarships, recognizing top work in math, science or engineering among undergraduates nationally.
