Science on the SPOT: Albino Redwoods, Ghosts of the Forest

Pale ghosts that hide amidst their gigantic siblings, only a few dozen Albino redwood trees are known to exist. They are genetic mutants that lack the chlorophyll needed for photosynthesis-- how and why they survive is a scientific mystery. QUEST ventures into the deep canopy of Henry Cowell Redwoods State Park near Felton, California to track down these elusive phantoms of the forest.

Going UP: Sea Level Rise in San Francisco Bay

Scientists say it's no secret San Francisco Bay is rising, along with all of the earth’s oceans. The reason -- global warming. This rise in sea level will affect everyone who lives, works, or plays near the bay. QUEST asks how high will the Bay rise and when? And what steps can communities take to plan for it?

Homegrown Particle Accelerators

QUEST journeys back to find out how physicists on the UC Berkeley campus in the 1930s, and at the Stanford Linear Accelerator Center in the 1970s, created "atom smashers" that led to key discoveries about the tiny constituents of the atom and paved the way for the Large Hadron Collider in Switzerland.

Science on the SPOT: Science of Fog

San Francisco 's fickle summer weather has earned it the nickname "Fog City." Science on the SPOT asks UC Berkeley's Todd Dawson to clear up the mysterious origins of this weather phenomenon, and share his research on how fog is integral to our state's ecology.

Restoration of the San Joaquin River

Flowing 330 miles from the Sierras to the delta, the San Joaquin River is California’s second longest river. It once boasted one of the state's great salmon runs. But since the construction of Friant Dam near Fresno in the 1940s, most of the San Joaquin's water has been siphoned off to farmland in the Central Valley. Now, after years of lawsuits, a new effort to restore the river is offering hope that fish and farmers can co-exist.

Ants: The Invisible Majority

Most of us think ants are just pests. But not Brian Fisher. Known as "The Ant Guy," he's on a mission to show the world just how important and amazing these little creatures are and in the process, catalog all of the world's 30,000 ant species before they become casualties of habitat loss. But he can't do it without our help.

Science on the SPOT: Marine Sanctuary Patrol Flight

The Channel Islands, Monterey Bay, Gulf of the Farallones and Cordell Bank National Marine Sanctuaries cover more than 9,500 square miles of ocean habitat. While most fishing and shipping are still allowed within sanctuary waters, some activities are now regulated or prohibited. Patrolling such an immense area by boat would take days... but now sanctuary managers are taking to the air in a rugged de Havilland DHC-6 Twin Otter bush plane to get a bird's eye view.

Web Extra: Music of the Sun

In this QUEST web extra, Stanford University astrophysicist Todd Hoeksema explains how solar sound waves are a vital ingredient to the science of helioseismology, whereby the interior properties of the sun are probed by analyzing and tracking the surface sound waves that bounce into and out of the Sun.

Journey Into The Sun

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. The data will allow researchers to learn about solar storms and other phenomena that can cause blackouts and harm astronauts.

Hepatitis C: The Silent Epidemic

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.

The Great Migration

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.

QUEST Lab: Bridge Thermometer

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.

Science of Taste

Did you know that about 95 percent of what we think is taste is actually smell? Or that the way we perceive flavor comes from a complex relationship between our senses, emotions and memories? As scientists decode how our taste and olfactory receptors work, top California chefs are taking that knowledge and creating alchemy in the kitchen.
