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.
If scientists are allowed to perform a simple genetic engineering procedure, they will be able to offer a reprieve to a small group of women who are condemned to pass certain fatal genetic diseases to each and every one of their children.
Drivers hit thousands of animals every year on California freeways, often killing the wildlife, and sometimes killing or injuring the human, too. Several western states have built fencing and other infrastructure to help wildlife cross freeways safely, and critics say California could be doing a lot more of the same.
Research at UC Davis identifies a new biological mechanism that links maternal infections during pregnancy to increased risk of having a child with a neurodevelopmental disorder like autism.
Governor Jerry Brown has approved the first statewide lead bullet ban for hunters, in the hope of helping endangered California condors.
Male California tarantulas are now roaming through the Bay Area looking for love. Find out more about where you can see them, what they're doing and what dangers they face from naturalist Sharol Nelson-Embry.
Imagine if instead of digging oil up out of the ground and refining it into gasoline, we could just have bacteria make it for us in a big vat somewhere. Researchers from South Korea have done just that -- engineered bacteria to make gasoline -- but many challenges remain before large scale production becomes viable.
The city of Watsonville has an expensive problem on its hands: toxic algae stirred up from the bottom of Pinto Lake makes the lake poisonous to humans and deadly to birds, fish, and even the otters in Monterey Bay, where the lake water eventually empties into the sea. Knowing how to clean it is one thing; paying for it is another.
New research shows that market squid may have something to offer the engineering sector: skin cells that can switch between transparent and white. Humans could use these cells to develop new bio-inspired materials; squid probably use them for cross-dressing.
