Scientists from federal and state agencies are regularly collecting samples of the water in the Chicago Area Waterway System looking for DNA cells that have been shed by Asian carp. Finding this environmental DNA (eDNA) would indicate the invasive species is present in the area.
The art and science of salt glaze pottery requires skills and techniques acquired over generations of trial and error. Ben Owen III combines his family’s experiential knowledge of ceramics and additional scientific knowledge to create and improve his unique works of art.
When a megathrust earthquake strikes, scientists around the world know in seconds. But what about hundreds of years ago? How, exactly, do scientists know there was a megathrust quake on the Cascadia Subduction Zone on January 26, 1700 between 9:00 and 10:00 p.m.? The answer lies in a ghost forest discovered on the Washington coast that reveals the secrets of one of the most powerful earthquakes to hit the planet.
QUEST takes to the high seas with researchers Dirk Rosen, James Lindholm and their crew to study the underwater world off the California coast. In recent years, the state has established a network of marine protected areas to help fragile habitats and struggling fish populations bounce back. But are they working?
Half of the airborne mercury pollution in the US comes from coal-fired power plants. After years of study and debate, the Environmental Protection Agency is planning to announce new limits on mercury from coal plants in November. Meanwhile, utilities are scrambling to meet other new federal regulations and industry groups are asking the government to slow down.
In California, more renewable energy comes from geothermal energy than solar and wind, combined. Today, a new technology known as Enhanced Geothermal Systems has the potential to extract even more heat and consequently energy to power steam turbines, but it’s not without challenges.
On the windswept tarmac of the former Alameda Naval Air Station, an inventive group of scientists and engineers are test-flying a kite-like tethered wing that may someday help revolutionize clean-energy. QUEST explores the potential of wind energy and new airborne wind turbines designed to harness the stronger and more consistent winds found at higher altitudes.
Studying the effects of a concussion at its source, inside the brain, is no easy feat. Says Dr. Geoffrey Manley, Chief of Neurosurgery at San Francisco General Hospital, "What we’re dealing with is one of the most complicated injuries in the most complicated organ in the body."
Kenneth Balcomb, senior scientist at the Center for Whale Research Friday Harbor, Washington, explains the connection between the Southern Resident killer whales (orcas) and chinook salmon.
