KQED Science Video Podcast: Episodes

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 ...
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 ...
They are otherworldly creatures who glow in the dark, without brains or bones, some reaching 100 feet long. And they live just off California's coast. Join two top marine biologists who have devoted their careers to unlocking the mysteries of jellyfish and alien-like siphonophores.
In our second episode of Science on the SPOT, join us on a behind-the-scenes trip deep into the massive collection of marine mammal skulls at the California Academy of Sciences in San Francisco. You'd be surprised how much you can learn about an animal's life– and death– by reading their bones.
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.
Test your knowledge about this mysterious, awesome and most vital of stars.
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 ...
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 ...
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 ...
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 ...
What's the coolest critter in the ocean under 4 inches long? The Dwarf Cuttlefish! These little guys can change their color and texture, and feeding time is a show like no other. Get an up-close look at these tiny underwater aliens as QUEST visits them at the California Academy of Sciences.
Is there a difference in taste between eggs gathered right from the farm and ones bought at the supermarket? Sebastian Nava, Research Assistant at the Culinary Institute of America, Greystone, presents his ongoing study of store-bought eggs and their country cousins.
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 ...
Imagine every person on earth had 100 pounds of plastic. That's how much new plastic will be manufactured in 2010. Sadly, much of that will end up in the ocean within a massive area dubbed the Pacific Garbage Patch. Can anything be done to clean it up?
Our companion story to "Catching Up on Sleep Science", this short segment serves as a quiz for viewers to test their knowledge about sleep and sleep disorders.
Everyone can appreciate the value of a good night's sleep. But did you know that a lack of sleep can have real consequences for your health? QUEST investigates how sleep affects our minds and bodies and uncovers why some people are genetically programmed to need less sleep than others.
In our first installment of QUEST's new Science on the SPOT web series, we go behind-the-scenes at the Monterey Bay Aquarium, with the intrepid dive team who keep the enormous Outer Bay Exhibit tank spic and span-- while swimming in 40 pounds of stainless steel, shark-resitant armor.
Along with cable cars and seagulls, the Golden Gate Bridge foghorn is one of San Francisco’s most iconic sounds. But did you know that if you hear that foghorn off in the distance, you can calculate how many miles you are from the bridge? Using the Speed of Sound exhibit at the Outdoor Exploratorium ...
Over the years The Monterey Bay Aquarium has had success holding a handful of great white sharks in their enormous outer bay exhibit. In the process scientists have learned much about these animals and millions of visitors have gotten a chance to meet a live white shark up close and personal.
The new self-anchored suspension bridge being built to replace the vulnerable eastern span of the Bay Bridge is scheduled to open in 2013 and will be seismically and aesthetically revolutionary in its design. QUEST explores the engineering features that will give the new bridge the strength and flexibility ...
