Reservoirs of silica-rich magma – the kind that causes the most explosive volcanic eruptions – can persist in Earth’s upper crust for hundreds of thousands of years without triggering an eruption, according to new University of Washington modeling research.

That means an area known to have experienced a massive volcanic eruption in the past, such as Yellowstone National Park, could have a large pool of magma festering beneath it and still not be close to going off as it did 600,000 years ago.

“You might expect to see a stewing magma chamber for a long period of time and it doesn’t necessarily mean an eruption is imminent,” said Sarah Gelman, a UW doctoral student in Earth and space sciences. (more…)

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…)

Crab Sagas Yield Insight into Sustainable Fisheries

Decades of wild swings in crab populations – some natural, some human-caused – dramatize the myriad issues surrounding questions about sustainable fisheries and the ecosystems that support them.

So said David Armstrong, professor and director of aquatic and fishery sciences, in his Jan. 5 talk “Claws, causes, climate and corps: A cavalcade of true crab sagas.” (more…)

Berkeley Lab to Build Cost Model for Fuel Cells

*A $2-million award from DOE will help bring down the cost of next-generation fuel cells.*

Fuel cells seem like an ideal energy source—they’re clean, efficient, silent and don’t require transmission lines. The hitch? They can be costly. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) hope to change that equation by building a sophisticated cost model that will take into account the total cost of ownership.

With a $2-million grant from the U.S. Department of Energy, a team of scientists led by Eric Masanet will perform a detailed assessment of fuel cell design and manufacturing that takes into account both intrinsic and external benefits. The aim is to quantify not only traditional manufacturing costs but also benefits that may previously have been overlooked and may ultimately bring down the cost of fuel cells. (more…)
