NASA’s fallen astronauts, including University of Colorado Boulder alumni Ellison Onizuka and Kalpana Chawla, who died in space shuttle accidents 17 years apart, will be remembered both on campus and in a special NASA online tribute this week.

Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at the world’s northern reaches, according to a new paper.

Cities that host bike-to-work events as their sole effort to increase commuter travel by bicycle may be missing a larger -- perhaps more valuable -- opportunity, according to a study involving the University of Colorado Boulder and led by the University of Colorado Denver . Local governments should use bike-to-work days to find out from participants why they’re attending and -- more importantly -- what prevents them from biking more often, according to the study.

When evacuees become separated from their pets while fleeing hurricanes, wildfires or other natural disasters, they’re often difficult to reunite. Computer scientists at the University of Colorado Boulder hope to change that with a new online tool designed to leverage the work of crowds to reconnect pets with their human families.

The Tibetan Association of Colorado (TAC) and the University of Colorado Boulder will co-host a campus visit of His Holiness the Dalai Lama on Oct. 20 and 21, 2015, both groups announced today. A schedule of events at CU-Boulder is still being finalized. The schedule and ticket information will be announced in the months ahead.

University of Colorado Boulder researchers will update NASA officials next week on a revolutionary space telescope concept selected by the agency for study last June that could provide images up to 1,000 times sharper than the Hubble Space Telescope.

University of Colorado Boulder Distinguished Professor W. Carl Lineberger was honored today by the National Academy of Sciences (NAS) for his extraordinary scientific achievements.

Based on continued growth in fourth-quarter new business filings in Colorado -- including entity renewals, trademarks and trade name registrations -- employment in the state is projected to expand through the first and second quarters of 2015, according to a University of Colorado Boulder report released today by Colorado Secretary of State Wayne Williams.

Remittances, or money transfers, sent home by migrant workers to developing nations play a key role in reducing poverty and improving welfare in recipient countries, according to a University of Colorado Boulder study.

To accurately forecast wintertime bad air days in Utah’s Uintah Basin, researchers must use real atmospheric measurements to estimate chemical emissions from nearby oil and natural gas fields, a new study in Atmospheric Chemistry and Physics has found.
