Cleared and stained skeletons are strikingly beautiful. But not many people outside the lab would ever know it—until now. "Cleared" is an exhibit of stained fish skeletons currently on display at the Seattle Aquarium, prepared and photographed by Adam P. Summers. Recently, Summers and his colleagues used a cleared and stained manta ray to discover how these curiously flat fish filter food out of the water.
The work of finding and describing species new to science isn't just something Charles Darwin did. Scientists at Bay Area institutions have discovered ants in Madagascar, barnacles in the Gulf of Guinea and legless lizards here in California.
Watching wild salmon swimming upstream isn’t just for for people with a television. This is the time of year for people in the San Francisco Bay Area to leave their couches and watch the endangered coho salmon (Oncorhynchus kisutch) spawn in Marin! There are three main viewing sites in Marin, although the Leo T. Cronin […]
Imagine a world where your experiences can be passed on to the next generation. Scientists don’t yet know if this happens in people, but they have now confirmed in a new study that this sort of thing does happen in mice.
The city of Martinez turned its creek flooding problem into a downtown asset and gained some famous beavers in the process. Learn how beavers benefit the creek ecosystem and where you can see them at the Martinez Regional Shoreline.
The obscure rare-earth metals turn out to be unexpectedly essential to life in hot volcanic mud--and probably elsewhere.
The FDA challenge may hurt the personal genetics industry in the short run. No traits, no health risks -- no fun. But the company is still allowed to show ancestry results. 23andMe's map of my distant relations offered a glimpse of the movement of people across the world. The more people who joined and shared their genomes, the more comprehensive a picture we could form of a global family tree. A day might come when I would know precisely how related I was to, for example -- you.
In response to a letter from the FDA, a direct-to-consumer (DTC) genetic testing company in Mountain View, California called 23andMe has agreed to stop providing health data on new purchases of its $99 genetic tests.
These charismatic critters draw a lot of attention and are thriving in local creeks, lakes and estuaries.The River Otter Ecology Project is working on the first-ever population assessment of these animals throughout the Bay Area.
Some men are unknowingly raising kids that are not biologically related to them, but until recently, the numbers were uncertain. Now that DNA testing is becoming cheaper and easier, better data has become available.
Learn about the legacy of former local conservationist Elsie Roemer and the marshland shorebirds sanctuary named in her honor in Alameda.
People who fight and study fire generally agree that one of the best tools for preventing massive wildfires is prescribed burning: intentionally setting smaller fires before the big ones hit. But there are major challenges to fighting fire with fire.
A new cap on the number of crab traps could help Bay Area fishermen--and maybe keep fresh crab in your local market a bit longer.
Nature's inventiveness often inspires human innovation, as in the well-known case of Velcro. Learn about other inventions featured in "Hidden Heroes: The Genius of Everyday Things," an exhibit currently on display at the San Jose Museum of Art.
The crisis of post-traumatic stress disorder -- both for newly returned vets and Vietnam vets who have lived with PTSD for decades -- is forcing the US military to explore some unorthodox treatments, including "compassion meditation."
A NASA scientist sums it up: “If we ever get star travel, we’ll probably see a lot of traffic jams.”
Parents can and do have children who look very different from themselves, but lack of understanding of genetics have led to authorities taking children away from them.
Something strange and unsettling is happening to Bay Area honeybees. Entomologists at San Francisco State University have identified the culprit: a tiny parasitic fly is causing the bees to exhibit bizarre nocturnal behaviors before suffering a gruesome demise.
Every September, the majestic sandhill crane migrates by the thousands from their breeding grounds as far north as British Columbia to the San Joaquin Valley Delta to fatten up for the next breeding season. Their long-term survival depends on innovative collaborations between conservation biologists and farmers to manage agricultural land as high-quality habitat.
