Berkeley Lab researchers successfully use distributed acoustic sensing for seismic monitoring

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

EAST LANSING, Mich. — Imagine a runaway boxcar heading toward five people who can’t escape its path. Now imagine you had the power to reroute the boxcar onto different tracks with only one person along that route.

Would you do it?

That’s the moral dilemma posed by a team of Michigan State University researchers in a first-of-its-kind study published in the research journal Emotion. Research participants were put in a three dimensional setting and given the power to kill one person (in this case, a realistic digital character) to save five. (more…)

ANN ARBOR, Mich.—Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. And it’s smaller than a penny.

“In a tiny amount of space, we’ve been able to make a device that generates more power for a given input than anything else out there on the market,” said Khalil Najafi, one of the system’s developers and chair of Electrical and Computer Engineering. (more…)
