Lighter than an SUV and covered with more than 12,000 solar cells, Solar Impulse, the world's first solar plane that can fly day and night without recharging, launched from Moffet Field this morning in a cross country voyage.
Apex predators exert far-reaching effects on ecosystems that surface just decades after their disappearance. Santa Cruz researchers hope to understand how human activities and development affect how pumas use the landscape to help mitigate conflicts and plan for the species' long-term survival.
Last week, scientists and regulators from more than 20 countries gathered in San Francisco to discuss the latest research on flame retardants. The conference lasted four days, but the theme of the meeting was clear from just a few talks: Do we need toxic chemicals to achieve fire safety?
Six years after the EPA's new arsenic rule for drinking water went into effect, poor communities in the San Joaquin Valley—who can’t afford the costs of complying with the stricter standard—face the highest risk of exposure to unsafe arsenic levels.
After federal wildlife officials removed endangered species protections on wolves in the Rocky Mountains, hunters quickly killed them by the hundreds. If California's lone wolf leaves the state, he could meet a similar fate.
Countless consumer products sold in California contain a flame retardant flagged as a possible carcinogen nearly 35 years ago. As of this week, finally, they must carry a warning that the chemical causes cancer. But is it enough when manufacturers simply replace one toxic chemical with another?
KQED SCIENCE is hosting its first Google+ Hangout On Air round table discussion about the proposed expansion of the Monterey Bay National Marine Sanctuary from 1-2PM PDT.
Every two years the staff of the magazine I edit, Home Energy, is invited down to the Asilomar Conference Grounds in Pacific Grove, California, to publish a daily newsletter for the biennial ACEEE Summer Study of Energy Efficiency in Buildings.
Learning to see the landscape through the eyes of a wild carnivore helps Bay Area residents appreciate the essential ecological roles bobcats, mountain lions, and other predators play in ecosystems. New research shows that lion leftovers feed a surprising diversity of other species.
Here's today's KQED Science round-up of science, nature and environment news from the Bay Area and beyond.
California farmworkers work long days for about $7.50 an hour to pick fruit in orchards doused with nitrogen fertilizers. A UC Davis study released in March found that nitrates from fertilizers and dairy waste have contaminated groundwater supplies. Because farmworkers live near the fields they work in, they're at high risk for nitrate-contaminated drinking water.
More than 40 years ago, Sen. John Dunlap (D-Napa) made conservation history when his mountain lion hunting moratorium passed the California Legislature and became law in 1971. He recalls the fight to pass the bill and his guiding principle, "when in doubt, preserve."
A "Bay-Friendly" gardens initiative is underway around the Bay Area under the sponsorship of Stopwaste.org. Last weekend some generous, certified “Bay-Friendly” garden owners opened their yards for tours.
Using grizzly bears in the Pacific Northwest as a proxy for the benefits salmon deliver to ecological communities, a new study argues that letting more salmon migrate into coastal streams will lead to downstream improvements for the ecosystem and eventually the offshore salmon catch.
The Great Backyard Bird Count gives novice Bay Area wildlife watchers the chance to play field biologist in their own backyards and help scientists gather data on the incidence, abundance, and distribution of birds. Researchers will use sightings to identify trends that will help conserve these valuable indicators of biodiversity.
