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鈥檚 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鈥檚 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鈥檚 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鈥檚 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.

A person鈥檚 style of speech 鈥� not just the pitch of his or her voice 鈥� may help determine whether the listener perceives the speaker to be male or female, according to a University of Colorado Boulder researcher who studied transgender people transitioning from female to male. The way people pronounce their 鈥渟鈥� sounds and the amount of resonance they use when speaking contributes to the perception of gender, according to Lal Zimman, whose findings are based on research he completed while earning his doctoral degree from CU-Boulder鈥檚 linguistics department.

With 14,000 original photographs and publications largely from the nineteenth and early-twentieth centuries, the recently acquired Ira Wolff Photographic History Collection offers a major scholarly resource for the study of the history of photography.
