Science at Breakfast

Professor Jing Shi and colleagues have used an organic semiconductor – instead of a conventional semiconductor such as silicon – to make switch-like “spin valves” that can control the flow of electrical current. The researchers were able to change the flow of electricity through the valves by 40 percent. This advance in a field known as “spintronics” is an early step toward a new generation of miniature electronic devices such as computer memory chips, light-emitting diodes for displays and sensors to detect radiation, air pollutants, light and magnetic fields.

Fresh Voices on Stale Air

Air pollution is a Salt Lake Valley problem without an easy solution. So University of Utah materials engineer Dave Richerson is tapping an unusual source for ideas to clean up our air: He’s going into classrooms to ask fifth, sixth and eighth graders how they would tackle the problem. Read More

Cell Phone Users Drive Like Old Folks

If you have been stuck in traffic behind a motorist yakking on a cellular phone, a new University of Utah study will sound familiar: When young motorists talk on cell phones, they drive like elderly people, moving and reacting more slowly and increasing their risk of accidents. Read More
