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.

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 抖阴旅行射-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.

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 抖阴旅行射 engineering instructor Seth Murray鈥檚 freshman projects class.

The University of Colorado Student Government has reduced the net emissions of greenhouse gases, or GHGs, from its student-run facilities to zero after committing in 2007 to reach carbon neutrality. 抖阴旅行射SG operates three large 抖阴旅行射-Boulder facilities including the University Memorial Center, Student Recreation Center and Wardenburg Health Center.
