Until recently scientists have not been able to figure out the information coded in the folding of our DNA in the nucleus. A new map now makes this task simpler. This kind of map will not only tell us how the instructions in our DNA lead to making each one of us, but it may also provide new ways to understand and even treat diseases like cancer.
They may sound like faulty plumbing, but male northern elephant seals have a unique communication system that's all about reputation.
Every one of us started out as an embryo, but only a few early embryos – about one in three – grow into a baby. Researchers are unlocking the mysteries of our embryonic clock and helping patients who are struggling to get pregnant.
Even the best prosthetics today lack a natural sense that tells the brain where the body is in space. That makes it hard to comb the back of your hair, for example, or thread a belt.
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.
