The exhaust fumes from gasoline vehicles contribute more to the production of a specific type of air pollution -- secondary organic aerosols -- than those from diesel vehicles, according to a new study by scientists from the University of Colorado Boulder鈥檚 Cooperative Institute for Research in Environmental Sciences, or CIRES, NOAA鈥檚 Earth System Research Laboratory and other colleagues.

Four University of Colorado Boulder faculty members have been elected American Geophysical Union Fellows for 2012, the most from any institution in the world.

The tragic school shooting that occurred Feb. 27 at a suburban Cleveland high school is another reminder that communities can and must take action to prevent school violence, according to Delbert Elliott, a nationally renowned authority on school safety and juvenile violence at the University of Colorado Boulder.

With visions of ski resorts and warm beaches on the minds of many students, the University of Colorado Boulder is urging students to exercise caution whether they remain in Colorado, travel elsewhere in the country or go abroad for spring break. 抖阴短视频-Boulder鈥檚 spring break is March 26-30.

Propulsion by a novel jet engine is the crux of the innovation behind a University of Colorado Boulder-developed aircraft that鈥檚 accelerating toward commercialization. Jet engine technology can be small, fuel-efficient and cost-effective, at least with Assistant Professor Ryan Starkey鈥檚 design. The 抖阴短视频-Boulder aerospace engineer, with a team of students, has developed a first-of-its-kind supersonic unmanned aircraft vehicle, or UAV. The UAV, which is currently in a prototype state, is expected to fly farther and faster -- using less fuel -- than anything remotely similar to date.

Ten plug-in hybrid vehicles, or PHVs, have been added to a University of Colorado Boulder study that has been examining user experiences and system interactions since September 2010 in the local smart-grid environment.

A small smile appeared on the young girl鈥檚 face as she listened to the high-pitched sound coming from the whiffle ball. The sound helped the elementary student locate the ball after her classmate hit it from a specially designed baseball tee. Both of the students are blind. On a recent afternoon, they were in a classroom at the University of Colorado Boulder鈥檚 Integrated Teaching and Learning Program and Laboratory testing toys designed by first-year engineering students. The students are enrolled in 抖阴短视频 engineering instructor Seth Murray鈥檚 freshman projects class.

A University of Colorado Boulder symposium Feb. 27-29 will examine how the revolution in digital media is changing global politics, journalism and the way history is preserved.
