The American chestnut was the king of the trees in forests in the eastern U.S. until a fungus from Asia brought them down. We are getting very close to making a resistant American chestnut. Now the question is whether or not we should plant it out in the wild.
If your town were suddenly struck by an earthquake or hurricane, you could count on the arrival of police, firefighters, and medical technicians to aid in the emergency response. As of this past January, the US government has added a new team of responders to this list—scientists.
While most people are out enjoying the warmer weather spring offers, there are some who cannot wait to make their way underground. With the rainy season behind us, California Caverns are opening up for those who aren't afraid of the dark.
If you’re a scientist these days, getting the money to do your research is a lot like getting into Stanford or Yale. Assuming you aren’t rich or connected, being incredibly skilled, hardworking and accomplished isn’t enough. You need to get lucky too.
Now that scientists are starting to get a handle on what kinds of microbes live in the human body and, roughly, how those populations differ from one individual to another, a key question will be whether there is such a thing as an “ideal” microbiome.
The European Space Agency's Planck mission has generated a map of the infant universe that refines our understanding of what it's all made of and has upped its age by 100 million years.
An hour of crowded freeway or a jaunt through granite, greenery and history? The choice is yours.
Apex predators exert far-reaching effects on ecosystems that surface just decades after their disappearance. Santa Cruz researchers hope to understand how human activities and development affect how pumas use the landscape to help mitigate conflicts and plan for the species' long-term survival.
Just north of the Bay Area is a vast and varied expanse of land and water that could be in line for new federal protections. The proposed Berryessa-Snow Mountain National Conservation Area would link wilderness zones and other lands in five counties. But it’s been a tough sell in some parts.
As a space-faring culture, we have now left our marks across the solar system, on planets, moons, asteroids, and in the empty space between them. Some of these “marks” are yet-functioning robotic spacecraft. Some are litter, scattered about the place like so many discarded soda cans, plastic grocery bags, depleted batteries, and defunct electronic devices. Are we trashing our solar system?
Last week, scientists and regulators from more than 20 countries gathered in San Francisco to discuss the latest research on flame retardants. The conference lasted four days, but the theme of the meeting was clear from just a few talks: Do we need toxic chemicals to achieve fire safety?
The Supreme Court is hearing a case on a key question: can you patent a human gene?
It takes a million years to make a land this big and flat. Take a few hours to experience it.
Don’t count on mitochondrial DNA (mtDNA) ancestry tests giving you a broad understanding of your own family history. They won’t.
As the whale migration season reaches its peak, new concerns arise over naval training exercises off the California coast.
