How Does Human Culture Influence Our Genetics?

The way our ancestors ate, cooked, explored, and interacted with others has had a profound influence on our genetic inheritance. So how will modern culture shape the genetic legacies we leave to our descendents? » 4/14/14 11:19am Monday 11:19am

Biologists Have Built An Artificial Chromosome From Scratch

In a breakthrough seven years in the making, an international team of scientists have reconstructed a synthetic and fully functional yeast chromosome. It's a remarkable advance that could eventually lead to custom-built organisms — humans included. » 3/28/14 2:20pm 3/28/14 2:20pm

Now Police Can Reconstruct Your Face From DNA Evidence

Criminals who inadvertently leave traces of their DNA at the crime scene now have something more to worry about. By isolating 24 genetic variants, researchers have developed a computer program that can construct surprisingly accurate 3D models of facial features. » 3/21/14 4:00pm 3/21/14 4:00pm

Would You Customize Your First Born Child?

The recent announcement by a British medical ethics board in favor of an experimental three-parent IVF treatment—wherein the genetic material from three donors, not the usual two, is used to create a fetus—and has once again stirred the pot of reproductive controversy. So where exactly is the line between prenatal… » 3/16/14 6:02pm 3/16/14 6:02pm

Scientists Create Genetically Modified Cells That Protect Against HIV

The treatment is considered radical, and the results were drawn from a small scale human trial, but for the first time in medical history, researchers have boosted their patients' ability to fight HIV by replacing some of their natural immune cells with genetically modified versions. » 3/06/14 9:00am 3/06/14 9:00am

The genetics behind schizophrenia are more complex than we thought

An international team of researchers has found that the cause of schizophrenia is even more complex than already believed, with rare gene mutations contributing to the disorder. In two studies published in the journal Nature, they show that schizophrenia arises from the combined effects of many genes. » 1/23/14 6:20am 1/23/14 6:20am

Why Supercentenarians Hold the Key to Extended Life

Supercentenarians are rare people who have reached the age of 110 and remain fit. Amazingly, many of them never get sick, despite having some bad health habits in some cases. Scientists say it all comes down to genetics — which could lead to a gene therapy that promotes longevity. Here's how super-c's will help us… » 1/03/14 11:27am 1/03/14 11:27am

How smoker's breath saved this caterpillar's life

Meet the tobacco hornworm, a caterpillar that regularly eats tobacco leaves loaded with nicotine. Research now shows this little bugger has a strange and unique defense against hungry spiders: It "puffs out" nicotine, creating a kind of toxic bad breath. » 12/30/13 1:20pm 12/30/13 1:20pm
