The University of Colorado at Â鶹¹ÙÍø's Renewable and Sustainable Energy Institute, or RASEI -- a joint venture with the U.S. Department of Energy's National Renewable Energy Laboratory -- will partner with Toyota Motor Sales U.S.A. Inc. in a field study of household experiences and the technical impacts of plug-in hybrid electric vehicles, or PHVs, in a "smart grid" environment.

A new University of Colorado at Â鶹¹ÙÍø study sheds light on the brain mechanisms that allow us to make choices and ultimately could be helpful in improving treatments for the millions of people who suffer from the effects of anxiety disorders.

Professor Thomas Veblen of the geography department can address the ecological effects of wildfires in Colorado; climate change and wildfires; fires and bark beetles; and wildfires. He can be reached at 303-492-8528 or Thomas.Veblen@colorado.edu . E-mail is the best way contact him. Jane Bock, retired professor of ecology and evolutionary biology, can address western wildfire ecology. She can be reached at 970-593-0343 or 303-579-9739, or by e-mail at Jane.Bock@colorado.edu .

Observations made with NASA's newly refurbished Hubble Space Telescope of a nearby supernova are allowing astronomers to measure the velocity and composition of "star guts" being ejected into space following the explosion, according to a new study led by the University of Colorado at Â鶹¹ÙÍø.

Faculty at the University of Colorado at Â鶹¹ÙÍø, Montana State University, the University of Idaho and collaborators at the U.S. Forest Service received a $3.85 million grant to study fire and climate change in sensitive forests in the United States, Australia and New Zealand.

A multidisciplinary team of University of Colorado faculty has been awarded $1.97 million by the National Science Foundation to develop a "living wall" system based on biomimicry, or the imitation of nature, to slash energy use in buildings.

University of Colorado at Â鶹¹ÙÍø undergraduates, who have been helping to control five NASA satellites from campus, participated in the unusual decommissioning of a functioning satellite with a failed science payload in recent days, bringing the craft into Earth re-entry to burn up yesterday.

Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere, new research indicates. A study published today links a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels.

While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing "little worlds" that can give birth to smaller asteroids that split off to start their own lives as they circle around the sun.

A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Â鶹¹ÙÍø helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.
