A scaled, working model of the solar system built by engineering students at the University of Colorado Boulder will be officially unveiled at Andrews Hall on Feb. 11.

We’ve all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a study led by the University of Colorado Boulder suggests some plants are altruistic too.

Researchers have detected the presence of a pollutant-destroying compound iodine monoxide in surprisingly high levels high above the tropical ocean, according to a new study led by the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where the planet is headed in terms of increasing greenhouse gases and rising temperatures.

When a sun-gazing NASA satellite designed and built by the University of Colorado Boulder launched into space on Jan. 25, 2003, solar storms were raging.

A new NASA-led study involving the University of Colorado Boulder finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters. Ozone is both a major air pollutant with known adverse health effects and a greenhouse gas that traps heat from escaping Earth’s atmosphere. Scientists and policy analysts are interested in learning how curbing the emissions of ozone-forming chemicals can improve human health and also help mitigate climate change.

To reflect its broader focus, the Colorado Renewable Energy Collaboratory, a research consortium including the University of Colorado Boulder, the Colorado School of Mines, Colorado State University and the U.S. Department of Energy’s National Renewable Energy Laboratory has adopted a new name: the Colorado Energy Research Collaboratory.

A research team involving several scientists from the University of Colorado Boulder has found an unexpected silver lining in the devastating pine beetle outbreaks ravaging the West: Such events do not harm water quality in adjacent streams as scientists had previously believed.

Emissions from oil and natural gas operations north of Denver could add to ozone pollution in that region, according to a new study by researchers at the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences (CIRES).

University of Colorado Boulder faculty member John Gosling is one of 18 individuals honored today by the National Academy of Sciences for their outstanding scientific achievements.
