The San Francisco Peninsula Watershed, managed by the San Francisco Public Utilities Commission, is home to trails that offer access to remote wilderness, Northern California geology, and opportunities to appreciate the complexity of providing 2.4 million people with a clean water supply.
On October 12, 2008, Angel Island was ravaged by a wildfire. In just 2 days, 303 acres went up in smoke. We're visiting the island a year later to see how the land is recovering and learn how the fire helped one scientist unearth a bit if the island's history.
Local nature lovers can enjoy the rare opportunity to hike, bike, or ride their horses through pristine stands of old growth Douglas Fir, evergreen and fragrant coastal scrub while enjoying ridge-top vistas of our watershed lands, reservoirs, the Pacific Ocean and San Francisco Bay. To protect our watershed, hiking on the trail is restricted to docent-led ventures three days a week, with advanced registration.
Pescadero State Beach is no simple place. Scanning its expanse, you can see ocean beach, streams, grasses, cattails, bushy scrub, and tall, ancient trees. If you look more closely you can see over 250 species of birds. The landscape, especially at the water, is never the same two days in a row.
Less than an hour’s drive north from San Francisco, the 2,882 acres of Samuel P. Taylor State Park is within easy driving distance of some of northern California’s most dramatic outdoor scenery. The park features a unique contrast of coastal redwood groves and open grassland.
As sure as the earth moves in Berkeley, there's a volcano just off Skyline Boulevard. Not just any volcano. This one's laying on its side with its guts exposed. At Sibley Regional Volcanic Preserve, you'll find the rocky body and layered underpinnings of one of the largest volcanoes that once dotted our geologic neighborhood.
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, […]
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.
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 […]
Companies like GenoCAD allow users to piece together their own designer DNA. “Synthetic biology” seems like a contradiction in terms, doesn’t it? I mean, if it’s biological, it’s natural, right? And if it’s natural, then it’s not synthetic. Sure. Except that modern science has sorta blurred all those nice convenient boundaries. Nothing has demonstrated this […]
How can you tell when someone's smile is fake? See if you can tell from the 2 images below:* A real, spontaneous smile incorporates tiny muscles around the eye that are nearly impossible to contract at will. You can see this for yourself in an exhibit called "Polite Smile, Delight Smile" part of the Exploratorium's […]
I love my cell phone. We have a serious relationship. One that may be biologically predetermined. Let me explain. On New Year's Eve I brought my phone with me to San Francisco's Ocean Beach, where I traditionally go, rain or shine, to watch the year's last sunset. I was by myself, but I wasn't alone. […]
Which is bigger, an electron or an atom? If you're reading this science blog, you probably know the right answer. And that would make you a little more informed than the average American, according to a recent National Science Foundation report. Getting kids grounded in science at a young age can go a long way […]
Oil booms at Crissy Field. Credit: fredsharplesJust two days before a container ship hit the Bay Bridge, spilling 58,000 gallons of oil into the waters of San Francisco Bay, QUEST web producer Craig Rosa and I were at Crissy Field beach. We were photographing pelicans and recording dogs playing in the sand for an upcoming […]
Dave Barker of the Exploratorium gets some batting tipsWhen I think of baseball and science, I always remember poor Sammy Sosa. In 2003, he was suspended from seven games with the Chicago Cubs for using a bat that had cork in it–an illegal move, according to Major League Baseball rules. I certainly don't feel sorry […]
Image from Wikipedia, originally from socialfiction.orgI'm in mourning: In early September, Alex the African grey parrot mysteriously died. I never met Alex personally, but I've heard him speak. Yes, he spoke. He also counted. And he could tell you which of a pair of keys was the bigger one, or the yellow one. He was […]
On Labor Day at the Exploratorium, visiting artist Aeneas Wilder witnessed museum visitors toppling a sculpture he'd spent many painstaking days to create in our Seeing gallery. Earlier this summer, Aeneas carefully stacked pieces of specially measured wood, one at a time, until he'd constructed an enormous cage-like sphere. (To get a sense of its […]
