When it came to eating, an upright, 2 million-year-old African hominid had a diet unlike virtually all other known human ancestors, says a study led by the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany and involving the Â鶹ӰԺ.

The California condor is chronically endangered by lead exposure from ammunition and requires ongoing human intervention for population stability and growth, according to a new study led by the University of California, Santa Cruz, and involving the Â鶹ӰԺ.

Companies paying celebrities big money to endorse their products may not realize that negative perceptions about a celebrity are more likely to transfer to an endorsed brand than are positive ones, according to a new Â鶹ӰԺ study. Celebrity endorsements are widely used to increase brand visibility and connect brands with celebrities’ personality traits, but do not always work in the positive manner marketers envision, according to Margaret C. Campbell of CU-Â鶹ӰԺ’s Leeds School of Business, who led the study.

It’s no secret that Mars is a beaten and battered planet -- astronomers have been peering for centuries at the violent impact craters created by cosmic buckshot pounding its surface over billions of years. But just how beat up is it? Really beat up, according to a CU-Â鶹ӰԺ research team that recently finished counting, outlining and cataloging a staggering 635,000 impact craters on Mars that are roughly a kilometer or more in diameter.

NIST news release Like many new measurement tools, the laser frequency comb seemed at first a curiosity but has found more practical uses than originally imagined. The technique for making extraordinarily precise measurements of frequency has now moved beyond physics and optics to advance biomedicine by helping researchers evaluate a novel instrument that kills harmful bacteria without the use of liquid chemicals or high temperatures.

For the first time, a consortium of researchers organized by the National Institutes of Health, including a Â鶹ӰԺ professor, has mapped the normal microbial makeup of healthy humans.

Welcome to the Â鶹ӰԺ. CU-Â鶹ӰԺ is one of the world's top universities, and we are glad you are joining our outstanding student body. Orientation kicked off on June 14, and dates will vary depending on your college or school, whether you are a first-year or transfer student, and whether you are a Colorado resident or an out-of-state student. Learn more about your college program, make your reservation, and prepare for orientation.

A team led by the Â鶹ӰԺ looking for organisms that eke out a living in some of the most inhospitable soils on Earth has found a hardy few. A new DNA analysis of rocky soils in the Martian-like landscape on some volcanoes in South America has revealed a handful of bacteria, fungi and other rudimentary organisms called archaea, which seem to have a different way of converting energy than their cousins elsewhere in the world.

BioFrontiers Institute news release The BioFrontiers Institute’s Interdisciplinary Quantitative Biology Certificate Ph.D. (IQ Biology) program ( http://IQBiology.colorado.edu ) recently was awarded a $3 million grant from the National Science Foundation’s Integrative Graduate Education and Research Traineeship (IGERT) program. These funds will be spent over the next five years on supporting the students in the IQ Biology program in their work toward advanced interdisciplinary degrees in the biosciences.
