Stress breeds depression. Anecdotally, we all know that's the case, but scientifically speaking it's been a hypothesis that has until now remained unproven. A new study, however, reveals that chronic stress affects us at the genetic level, in turn creating very real brain changes associated with depression.
A new blood test which identifies a genetic change that doubles the risk of breast cancer could allow doctors to identify women at high risk of the disease years before they develop a tumor.
There are two hormones, oxytocin and vasopressin, that generally make us more sociable, more caring, and just generally nicer. But now scientists have taken this a step further by finding the specific genetic receptors that make these hormones so effective.
The gene PTEN is a tumor suppressor, making it one of the best genes to have in the fight against cancer. But the latest research suggests that preventing cancer is just the beginning of all the amazing things this gene can do.
A few years back, we learned that the Y chromosome was essentially rotting, shedding hundreds of its genes over the last 300 million years. That isn't wrong, but it turns out reports of the Y chromosome's eventual extinction were premature.
There seems to be one surefire way to increase longevity in animals. It's caloric restriction, which means placing them on a near-starvation diet. We don't know if that could work on humans... but fruit flies might be able to give us the answer.
On Wednesday scientists announced an exciting new potential cure for leukemia using gene therapy. Yay. Let's hope the test subjects don't get sick and die. Because that's what happened last time.
Our genes don't just help determine who we are — they also preserve an incredibly ancient record of who our ancestors were. Our genomes can actually reveal human population sizes dating all the way back to before humans even existed.
In the United States alone, 20 million people suffer from peripheral neuropathy, a condition that involves nerve degeneration and sometimes extreme pain, often without any explanation. Now we've found the culprit for this mysterious pain...and it's all one gene's fault.
In the first instance of gene transfer between a human host and bacteria, Gonorrhea was recently discovered to have a human DNA fragment. What the..how the..huh? Supposedly, it's a relatively recent evolutionary event and scientists have no idea what it means. And though it's a pseudo love story between star crossed…
The water flea species Daphnia pulex is barely more than a millimeter long, is completely translucent, has no clear divisions between their various body parts...and has the largest genome of any animal we've ever encountered. It has an incredible 31,000 genes in its genome, over 8,000 more than humans have. So what's…
Your friends might seem like an essentially random bunch, based on shared interests and emotional compatibility. But there might be something genetic going on - and it's related to how much you drink.
Is your political outlook in your genes? Researchers have identified a gene variant that could predispose adolescents to becoming liberal adults — but only if they have an active social life.
Buffy and Angel veteran Tim Minear may be in talks to head a revival of Gene Roddenberry's The Questor Tapes, but don't expect it to be a Whedonesque re-do, according to the man responsible for the property, Rod Roddenberry.
Know someone who seems congenitally incapable of driving? A new study suggests that a genetic variant may, in fact, be responsible for poor driving skills — and it's a variant nearly one third of Americans possess.
"Science Fiction has become an exclusively literary genre, with books inspired less by new scientific research than by previous science fiction books, and, regrettably, movies. Ideas turn into tropes, and instead of extrapolation, we get variation: of the generation star ship, the space alien, the artificial brain,…
You've gotta love the FCC. Well, not really, but they're certainly the biggest source of leaked phone info out there.
Cray, that maker of supercomputers from days of yore, has decided to jump into the biggest
computer contest, creating a machine it has given the prosaic name of "Baker." The company expects it to be the first computer to break the petaflop barrier. That is, unless IBM beats Cray to the punch with its…
