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.

Why We Need to Think Differently About Our Genomes

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

It Now Only Costs $100 To Know Everything About Your DNA

Mapping out your genome is the 21st Century equivalent of staring deep inside your soul; it's tempting to look, but terrifying what you might find. The DNA divers at 23andMe are hoping that slashing the price of their home-testing service—from $300 down to $100—will be enough to tilt the scales towards discovery. Are… » 12/13/12 8:58am 12/13/12 8:58am

The Human Genome Is Far More Complex Than Scientists Thought

For the past decade, scientists have been working on the assumption that 20,000 genes, less than 2 percent of the total genome, underpin human biology. But a massive international project called ENCODE has just revealed that plenty of the remaining 98 percent, once tossed aside as "junk DNA", is in fact incredibly… » 9/06/12 6:19am 9/06/12 6:19am

A Miracle Drug Keeps This 70-Year-Old Cancer Patient Running Marathons

Don Wright was diagnosed with myeloma—cancer in his blood cells and bone marrow—two weeks after running his first marathon. His doctor gave him a five-year survival estimate. Eight years later he has run 60 26.2-mile races in 41 states and takes just one pill per day to keep his cancer at bay. » 12/14/11 4:00pm 12/14/11 4:00pm
