QUEST@Cal is a series of episodes of KQED QUEST featuring the work of Cal scientists.
Physicists can't see it and don't know much about what it is, but dark energy makes up 70 percent of the universe. Meet one of the country's leading scientists trying to understand dark energy and the role it plays in causing our universe to expand. This video is from KQED QUEST.
The world's climate is changing and California is now being affected in both dramatic and subtle ways. Watch the KQED QUEST episode here.

Bio-inspiration: Nature as muse For hundreds of years, scientists have been poaching ideas from something that we all have access to — nature! This video is from KQED QUEST.
We all rely on the water cycle, but how does it actually 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. Find out more by watching this episode of KQED QUEST.
Scientists say the state's plants are at risk of collapse unless they migrate or are moved to refuges. Listen to this episode of KQED QUEST here.
Why are species of amphibians in serious decline globally — including right here in California? Join Professor Tyrone Hayes as he shares some startling revelations about this phenomenon.
Do other planets like Earth exist? To find out, a team of astronomers from the University of California is building a new telescope in the hills east of San Jose. QUEST finds out what the chances are that there are others like ours somewhere in the cosmos. Watch the episode.
In the early 1900's, researchers from UC Berkeley's Museum of Vertebrate Zoology traveled around California and created records of the wildlife they found. A century later, scientists are revisiting these sites — and find that global warming is having an impact. Watch the episode of KQED QUEST here.
For years there's been buzz – both positive and negative – about generating ethanol fuel from corn. But thanks to recent developments, the Bay Area is rapidly becoming a world center for the next generation of green fuel alternatives. Meet the scientists investigating the newest methods for converting what we grow into what makes us go. This video is from KQED QUEST
Northern California residents may not be able to see the northern lights like people in Alaska can, but Bay Area scientists are playing a key role in understanding them. Find out more about the spectacular light shows up north and what scientists at UC Berkeley are discovering about the Earth's magnetic field on this episode of KQED QUEST.
