In response to the major threats posed to the Great Lakes by invasive Asian carp, engineers have developed devices to keep them out, but delays in deciding how to implement them might give the fish an edge. ...Read More

Six out of every thousand people are estimated to be identical twins. This means that there are a lot of children being fathered by identical twins and that these twins are involved in a good number of crimes too. And until recently, none could be identified from just their DNA. This has all changed in a new study where scientists were able to reliably use DNA to tell two identical twins from each other.
There are more than a thousand species of sharks and rays in the world, and nearly a quarter of them are threatened with extinction. That means these ancient types of fish are among the most endangered animals in the world.
A non-invasive imaging method could help identify and localize artery-clogging plaques that are likely to cause a heart attack. If future studies confirm the initial results, this technique has the potential to fundamentally alter the way we treat heart disease.
A UCSF researcher explains how public pressure on makeup manufacturers seems to work, and why it's "common sense" to keep plastic dishware out of the microwave.
Researchers are launching a new project to monitor California's kelp forests for radiation from the Fukushima nuclear power plant in Japan. Scientists will fan out along the California coast to collect kelp and find out if it has absorbed any radiation from the 2011 meltdown.
As scientists struggle to find better ways to diagnose and treat mental disorders, an Exploratorium exhibition, "The Changing Face of What Is Normal," experiments with a new way to encourage people to think about what is normal.
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.
