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.
Mike Forsberg, a nationally renowned photographer, conservationist, and author from Nebraska, spent four years traveling 100,000 miles across the Great Plains—from North Dakota to Texas—to create a portrait of under-appreciated species and habitats of what many consider “flyover country.”
For more than 150 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.
Attention Galileo guys and gals – download any one of these astronomy apps for your smartphone and you can stop star-guessing and start star-gazing like a pro!
Steve Spomer has been involved in Salt Creek Tiger Beetle research for more than two decades. Spomer is now working with the U.S. Fish and Wildlife Service in a capture and recovery program to save the species.
New Jersey scientists study proliferating populations of sea nettles, which have made some waters un-swimmable.
Today at 6PM PST, The World Science Festival, Columbia University and NOVA are hosting a screening of 'What is Space?' to coincide with the 'NOVA: Fabric of the Cosmos' series premiere. Also included will be Saul Perlmutter, local Lawrence Berkeley Lab astrophysicist and winner of the 2011 Nobel Prize in Physics.
Rivers and streams have created pathways along the dividing line between the Great Lakes basin and the Mississippi River basin. These portals could allow water and aquatic nuisance species to move from one basin into the other, endangering the health of both water systems.
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.
