Genetically, we're all pretty much the same. A massive volcanic eruption 75,000 years ago may be why. Lake Toba is all that is left of the volcano that nearly wiped out mankind.Last blog I talked about how East Africans are genetically more diverse than Asians. Who are genetically more diverse than Native Americans. From all […]
Image source: Michael PatrickMany Bay Area cities are trying to clean up their acts by putting in place new green initiatives. But from San Jose to Berkeley, some city leaders are finding out it's not always so easy to turn over a new leaf. QUEST looks at the challenges municipalities face with budget constraints, legal […]
It's more than the genes that feed us. Some have dubbed it the "doomsday vault"; others, taking a more positive tone, call it a repository of biodiversity. However you look at it, the Global Seed Vault is a fortress. Buried under almost 500 feet of Arctic permafrost, secured against bomb blasts, earthquakes, and potential thieves, […]
It's almost spring: time for sultry nights, birds, bees, renewal and the sweet promise of new love. For us humans, that might mean flirty skirts, a new perfume, a dapper new hat or hip hair cut, all in the hopes of attracting a new, or very old and loyal, perfect mate. Plants also feel the […]
Just a few minutes outside of San Jose, you'll find a place to explore 100 million years of history. Alum Rock Park, created in 1872 as the first municipal park in California, offers both ancient rocks and new geologic changes (and lots of nice trails and wildlife, too). Despite its longevity and proximity to a populous urban area, it remains one of the less-visited jewels in the Bay Area's crown.
What will life be like when gasoline reaches $15 per gallon? We may have to slow down our too-often fast paced and frenetic lifestyles—a blessing in disguise? That's the question asked of a group of scientists, sociologists, others, and myself who gathered at the American Council for an Energy Efficient Economy (ACEEE) Summer Study in […]
A tiny moth, new to California, is at the center of a controversy pitting state officials against Bay Area residents and politicians. The Light Brown Apple Moth is seen as a threat to California crops. Now the State Department of Food and Agriculture is planning to spray a synthetic hormone over Bay Area neighborhoods this […]
The Light Brown Apple Moth is seen as a threat to California crops. Now the State Department of Food and Agriculture is planning to spray a synthetic hormone over Bay Area neighborhoods this summer to stop the moth from reproducing, but some angry residents are worried it would be unsafe.
Amundsen-Scott South Pole Station As the sun shines and the air warms in the Bay Area, take a moment to consider a place where it's always cold–the South Pole. Thanks to some local folk, we can get a taste of the science at the bottom of the earth without leaving balmy San Francisco. Berkeley graduate […]
Run down Recent news headlines have been full of Chinook salmon, but sadly the same cannot be said of Central Valley waterways. This fall, only about 90,000 Central Valley Chinook salmon returned to their home rivers and streams to spawn, down from more than 800,000 just a few years ago. Like most salmon, Central Valley […]

When news came in that not just one, but two sewage spills had poured five million gallons of partially treated wastewater into Richardson Bay, we […]
I had the privilege this week of interviewing Isabel Hawkins, an astronomer and director of the Center for Science Education at Berkeley's Space Sciences Laboratory. We talked about how people use evidence in science, how it is that we know what we know. Hawkins isn't your ordinary astronomer. She began her career in an ordinary […]
Concern over global warming and rising gas prices has just about everyone, including presidential candidates, touting biofuels. Taking the energy from plants to make a gasoline alternative that can run our cars has great promise. But there are challenges to meeting the nation’s goal to replace 20 per cent of the nations annual gasoline consumption […]

In Silicon Valley, a battle between neighbors has turned into a different kind of face off: solar energy versus trees. It turns out that growing redwood trees can actually be a crime in California, if they block solar panels… as one couple in Sunnyvale found out the hard way. David Gorn reports.
newly discovered Rhynchocyon udzungwensis the grey-faced sengiAlthough enigmatic new species of insects are fairly common discoveries, many large animals have already made an appearance on the species list. Charismatic animals such as mammals are one of the most documented on the planet and it is now very rare to find a new species in this […]
January and February are exciting months for movie buffs like me. And no, I'm not referring to Golden Globes, Oscar nominations, or Screen Actors Guild awards. I'm talking about two wonderful "green" film festivals, both right here in our own watershed: the recent Wild & Scenic Environmental Film Festival in Nevada City, and the San […]
