A new study confirms that at the DNA level, people in the U.S. are more similar than many might think. People who self identify as African-American, Latino or European-American very often have traces of one or both of the other ancestries in their DNA.
Until recently, you pretty much had to rely on family stories that were passed down through the generations to learn about your ancestors. But that is now set to change. With a little luck, a whole lot of science and genealogy, you may be able to use passed down DNA instead of stories to learn a bit about that great-great-great-grandfather.
Sea otters aren’t just cute -- they’re a vivid example of life on the edge. Unlike whales and other ocean mammals, sea otters have no blubber. Yet they're still able to keep warm in the frigid Pacific waters. The secret to their survival? A fur coat like no other.
In a stunning feat of scientific prowess, a large group of scientists has completely sequenced the genomes of 48 different bird species. But as sequencing gets easier, managing all of that data is turning out to be the real challenge.
Stanford researchers believe they’ve found a drug for cardiac stents that can more effectively prevent complications, because the drug targets the actual cause of stent disease.
It’s well-known that daylight length is an important migratory trigger, but a new study from UC Berkeley finds birds use infrasound, or tones lower than the normal range of human hearing, to flee bad weather.
A new book about marine invertebrates celebrates the sumptuous beauty of our lesser-known cousins.
What does it mean to be blue? The wings of a Morpho butterfly are some of the most brilliant structures in nature, and yet they contain no blue pigment -- they harness the physics of light at the nanoscale.
Here in the U.S., if you want to get health information from your direct-to-consumer (DTC) genetic test, you need to use an online resource like Promethease. The same is no longer true in Canada and the U.K.
Amphibians face tough times as nearly one-third of the species has already lost worldwide. Learn about our local amphibians and what the East Bay Regional Parks District is doing to protect them.
There is little doubt any more among the research community that sexual preference is a combination of both nature and nurture. In other words, it comes about because of both genes and the environment. The next questions to answer have more to do with how much each contributes and which genes and environmental factors are involved.
Migratory monarch butterfly populations have fallen into a tailspin in recent years. Scientists fear that in a classic case of good intentions gone awry, efforts to help the beleaguered butterflies may be inadvertently making matters worse by changing their behavior.
If you want to go to Mars but can’t quite afford the hundreds of billions of dollars for a ticket, there is another solution: consider instead a trip to the Atacama Desert in Chile.
Plenty of animals build their homes in oak trees. But some very teeny, tricky wasps make the tree do all the work. “What nerve!” you might say. What… gall! And you’d be right. The wasps are called gall-inducers. And each miniature mansion that the trees build for the wasps' larvae is weirder and more flamboyant than the next.
But the virus isn't new to sea stars, so what triggered the current outbreak remains a mystery.
