Scientists at Stanford University and Lockheed Martin are playing pivotal roles in a nearly billion-dollar NASA mission to explore the sun. A spacecraft launched in early 2010 is obtaining IMAX-like images of the sun every second of the day, generating more data than any NASA mission in history.
In this QUEST web extra, Stanford University astrophysicist Todd Hoeksema explains how solar sound waves are a vital ingredient to the science of helioseismology, in which the interior properties of the sun are probed by analyzing and tracking the surface sound waves that bounce into and out of the Sun.
Thousands of babies are born each year in the U.S. with brain defects that can cause lifelong disability or even death. UC-San Francisco neurologists and pediatricians are developing better diagnostic tools and treatments to help brain-damaged babies not only survive, but grow up to live more normal lives.
Now, after an exciting discovery at Lawrence Berkeley National Laboratory (LBNL), the hydrogen highway is a good idea whose time may have come around.
Hepatitis C is a virus that causes cirrhosis of the liver and liver cancer. It's the leading cause for liver transplants in the U.S., and an estimated 4 million Americans have the disease. Current treatments are difficult to tolerate and are often ineffective, but recent breakthroughs from Bay Area scientists may soon produce a cure for the disease that claims more than 10,000 American lives each year.
Voters in California will consider a measure on the November ballot to legalize and tax marijuana. Amid the debate over pros and cons, another issue has been gaining visibility — the environmental damage pot cultivation can incur. Illegal pesticide use and creek water diversion at large-scale outdoor operations are well-documented. But environmental concerns are also growing over indoor marijuana cultivation, as Lisa Morehouse reports.
Hardy’s lived in the hills of southern Humboldt County since the early ‘70s, when many people shared sense of idealism and environmental responsibility. That’s why he’s so upset about the environmental impacts of the big, indoor marijuana growing operations that have proliferated in the region.
For thousands of years and countless generations, migratory birds have flown the same long-distance paths between their breeding and feeding grounds. Understanding the routes these birds take, called "flyways," helps conservation efforts and gives scientists better knowledge of global changes, both natural and man-made. QUEST heads out to the Pacific Flyway with California biologists to track the rhythm of migration.
The roadway across the Golden Gate Bridge rises and falls as much as 16 feet depending on the temperature. When the sun hits the bridge, the metal expands and the bridge cables stretch. As the fog rolls in, the cables contract and the bridge goes up. Curators from the Outdoor Exploratorium in San Francisco have set up a scope two miles away so you can see how the bridge is moving up or down depending on the weather.
A plan being considered by California's State Water Resources Control Board would end the practice of allowing power plants along the coast to suck in ocean water to cool their machinery. Environmentalists say it kills millions of fish larvae, small animals and other ocean life, but the power industry says tighter rules would raise California's electricity prices, already among the nation's highest.
