Scientists Manipulate Genes to Make Old Organs Young Again (in Mice)

Researchers at the University of Edinburgh showed this week that they could teach an old mouse's thymus to bounce back to a healthy, youthful state, simply by manipulating a single protein that controls gene expression. It's the first time scientists have been able to regenerate a living organ by gene manipulation, and … » 4/10/14 10:10am 4/10/14 10:10am

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 2:00pm 3/16/14 2:00pm

Resurrecting Dinosaur-Age Proteins To Cure Human Disease

While dinosaurs have not yet been resurrected Jurassic Park-style, scientists fiddling with ancient DNA sequences have made a discovery that may turn out to be a tad more useful: a treatment for gout. That a 90 million-year-old protein could treat a modern disease is a fascinating window into evolutionary history. » 2/20/14 5:20pm 2/20/14 5:20pm

What Are GMO Foods, And Are They Okay To Eat?

The advent of genetically modified crops has promised heartier food and higher yields that could potentially reduce poverty and malnutrition rates the world over. Two decades later, they're also broadly maligned and mistrusted. But is it finally time to put down the pitchforks? » 2/19/14 3:00pm 2/19/14 3:00pm

The Science of Marrying Your Cousin

In modern western society, marrying your cousin is not well accepted, particularly in the United States. Through a combination of old prejudices and present-day conventional wisdom about inherited birth defects, first cousin marriage is seen by many as a little too close for comfort, as well as a bad idea if you want… » 2/14/14 7:00am 2/14/14 7:00am

The World's Oldest Tumor is 11,000 Years Old and Spread By Dog Sex

Somewhere 11,000 years ago, something weird happened to a dog. It got cancer—and the really damn freaky part is that the cancer could survive even outside of its canine host. That unknown dog is long dead now, but its tumor cells have improbably lived on, continuing to sprout on the genitalia of dogs all over the… » 1/24/14 5:40pm 1/24/14 5:40pm

8 Incredible Facts You May Not Know About Human Evolution

» 11/15/13 6:16pm 11/15/13 6:16pm

Homo sapiens evolved about 200-150,000 years ago in Africa, but our story as a species stretches back much further than that with early human ancestors. And the evolution of Homo sapiens is itself a tangled tale, full of unanswered questions and gothic family melodrama. Here are a few facts you may not know about the… » 11/15/13 6:16pm 11/15/13 6:16pm

Scientists Found the Wolverine Healing Gene

Deep within our bodies are all kinds of genes that turn on and off over the years, including the very genes that make you grow a body in the first place. This is where scientists are looking for the magical code that could enable us to regrow organs and regenerate limbs. A Harvard researcher thinks he might've found… » 11/07/13 4:20pm 11/07/13 4:20pm

Would You Eat This Cheese Made from Human Armpit Sweat?

Folks often shy away from fancy cheese because it smells like feet. But what if the cheese was actually made from feet—or rather, the bacteria that makes your feet stink? A couple of bio-hacker artists decided to explore that possibility. And it sounds really gross. » 10/24/13 2:40pm 10/24/13 2:40pm

Why We Need to Think Differently About Our Genomes

If—like most of us—your entire understanding of DNA and genetics can be traced back to CSI reruns, you’re probably under the impression that your genome is unique; that it defines you completely. But scientists increasingly believe that’s not that case. In fact, we need to start thinking about our genomes differently. » 9/20/13 9:40am 9/20/13 9:40am

These Glow in the Dark Rabbits Will Help Cure Diseases One Day

Glowing bunny rabbits aren't just for Sherlock Holmes reboots and acid trips anymore. Scientists from the University of Hawaii recently collaborated with a team from Istanbul, Turkey, where a couple of bright green lab rabbits were just born as part of a larger effort to better understand hereditary illness and make… » 8/13/13 6:20pm 8/13/13 6:20pm
