Show notes

Researchers at Lawrence Berkeley National Laboratory are pioneering a new way to recover 100-year-old recordings. Found on fragile wax cylinders and early lacquer records, the sounds reveal a rich acoustic heritage, including languages long lost.

Dark Energy Jul 22, 2008

Show notes

Meet one of the three winners of the 2011 Nobel Prize in Physics, Lawrence Berkeley Lab astrophysicist Saul Perlmutter. He explains how dark energy, which makes up 70 percent of the universe, is causing our universe to expand.

Tracking Raindrops Jul 22, 2008

Show notes

We all rely on the water cycle, but how does it really work? Scientists at UC Berkeley are embarking on a new project to understand how global warming is affecting our fresh water supply. And they're doing it by tracking individual raindrops in Mendocino and north of Lake Tahoe.

Your Photos on QUEST - Erin Malone Jul 22, 2008

Show notes

Join QUEST in our latest photography feature about viewers like you who love documenting science, environment and nature imagery here in the Bay Area. This week, meet Erin Malone, who makes beautiful, impressionistic images in a place that many overlook or see as ugly-- the subtly hued mud and marsh of South San Francisco Bay.

State of Thirst: California's Water Future Jul 15, 2008

Show notes

Are we in danger of running out of water? California's population is growing by 600,000 people a year, but much of the state receives as much annual rainfall as Morocco. With fish populations crashing, global warming, and the demands of the country's largest agricultural industry, the pressures on our water supply are increasing.

Web Exclusive: Tagging Pacific Predators Extended Interview May 20, 2008

Show notes

Why are Monterey Bay area scientists putting tuna on treadmills? See an extended interview with scientist Barbara Block at the Tuna Research and Conservation Center about her work to get a picture of their migration routes and ecosystem...through the tuna's eyes.to discover even more about lives of sea turtles, sharks and other Pacific predators.

Tagging Pacific Predators May 20, 2008

Show notes

It's easy to find them in a can, but the lives of tuna in the open ocean have been a mystery to scientists. Thanks to a tagging program, Monterey Bay Area scientists are learning that these underwater sprinters travel thousands of miles around the Pacific. Now they're also working to discover even more about lives of sea turtles, sharks and other Pacific predators.

Darfur Stoves Project May 20, 2008

Show notes

Everyday, women living in the refugee camps of Darfur, Sudan must walk for up to seven hours outside the safety of the camps to collect firewood for cooking, putting them at risk for violent attacks. Now, researchers at Lawrence Berkeley National Laboratory have engineered a more efficient wood-burning stove, which is greatly reducing both the women's need for firewood and the threats against them.

Nature Deficit Disorder May 13, 2008

Show notes

A growing number of children's advocates and political leaders are worried that our culture's disconnection from nature is harming kids.

Ugo Conti's Spider Boat May 13, 2008

Show notes

Bay Area engineer Ugo Conti has sailed the world, but has always suffered from seasickness. A queasy stomach became his motivation to design "Proteus" - a spider-like sea craft made for smoother sailing. He designed the Wave Adaptive Modular Vessel to cross the ocean while flexing with the movement of the waves. And it may change the way people take to the high seas.
