Hetch Hetchy Aqueduct: Big Fixes for Big Quakes Nov 09, 2011

Show notes

The San Francisco Public Utilities Commission is hard at work on a $4.6 billion, decade-long construction project to overhaul the Hetch Hetchy water system, which delivers water from the Hetch Hetchy reservoir in Yosemite National Park and five local reservoirs to 2.5 million residents in the Bay Area.

The Night Sky: Past and Present Nov 09, 2011

Show notes

For over one hundred and fifty years, scientists have captured images of celestial objects scattered across the night sky. The Pisgah Astronomical Research Institute in North Carolina is attempting to save those historical records before they vanish into a black hole.

Asian Carp: Threat to Great Lakes Nov 02, 2011

Show notes

The invasive Asian carp has wreaked havoc in the Mississippi River system. The voracious plankton eaters have out-competed native fish and have become the dominant species in many locations. If the carp reach the Great Lakes, they pose a threat to its $7 billion fishery, so a battle against them is taking place on many fronts.

Cool Critters: Lake Erie Water Snake Nov 02, 2011

Show notes

Within and along the waters of Lake Erie (one of the five Great Lakes), there is a daily struggle for survival between natives and unwelcomed invasive species.

Science on the SPOT: The Science of Salt Glaze Pottery Oct 27, 2011

Show notes

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.

One Fish Two Fish: Monitoring Marine Protected Areas Sep 28, 2011

Show notes

QUEST takes to the high seas with researcher Dirk Rosen 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?

QUEST Lab: Engineering Fire Sep 28, 2011

Show notes

In a dark lab at Lawrence Berkeley National Laboratory, engineers and mathematicians are developing new burners and studying different flames in hopes of better understanding the power of fire and how to make the most efficient flame possible.

Induced Seismicity: Man-Made Earthquakes Sep 21, 2011

Show notes

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.

Megathrust Earthquakes Sep 21, 2011

Show notes

Experts warn that an offshore quake powerful enough to kill thousands and discharge a tsunami could hit the West Coast anytime. QUEST Northwest talks with geologists and seismologists about cutting edge research in earthquake prediction, and what it would look like if the next "Big One" hits close to home.
