A techie with a dream sparks a new generation of computer scientists

Read the improbable story of a Microsoft employee who twice turned down a traditional tech sector job so he could teach high school students, and then landed his dream job.

REDMOND, Wash. — Kevin Wang could have followed his career.

Instead, he chose to follow his calling.

It was the early 2000s, and Wang had just graduated from Berkeley with a degree in computer science and electrical engineering. He was trying to decide which tech company he should offer his services to, when a high school came calling. (more…)

Flexing Fingers for Micro-Robotics: Berkeley Lab Scientists Create a Powerful, Microscale Actuator

Berkeley, Calif., Dec. 2012 — Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for microfluidics, drug delivery, and artificial muscles.

“We believe our microactuator is more efficient and powerful than any current microscale actuation technology, including human muscle cells,” says Berkeley Lab and UC Berkeley scientist Junqiao Wu. “What’s more, it uses this very interesting material—vanadium dioxide—and tells us more about the fundamental materials science of phase transitions.” (more…)
