Colorado business leaders are less optimistic going into the third quarter than last quarter, according to the most recent quarterly Leeds Business Confidence Index, or LBCI, released today by the Â鶹ÊÓƵ’s Leeds School of Business. The LBCI’s reading slid from 62.2 in the second quarter to 53.6 in the third, but remained higher than the 10-year average for the index and above the critical neutral mark of 50. A reading greater than 50 indicates positive expectations, while one lower than 50 indicates negative expectations.

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ÊÓƵ.

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ÊÓƵ.

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ÊÓƵ 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-Boulder’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-Boulder 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ÊÓƵ professor, has mapped the normal microbial makeup of healthy humans.

A team led by the Â鶹ÊÓƵ 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.

An international research team led by the Â鶹ÊÓƵ has generated the first laser-like beams of X-rays from a tabletop device, paving the way for major advances in many fields including medicine, biology and nanotechnology development.
