To scientists like Michael Snyder, chair of the genetics department at Stanford University, the future of medicine is data — lots and lots of data.

He and others predict that one day doctors won’t just take your blood pressure and check your temperature. They will scrutinize your genome for risk factors and track tens of thousands of molecules active in your body.

By doing so, the doctors of the future will identify diseases, and treat them, long before symptoms appear.

Seven Misconceptions about Heredity

In the cover story for the May/June issue of Skeptical Inquirer, I explore some of the biggest misconceptions about heredity. With the ongoing explosion of DNA testing, it’s urgent that we understand what the results of those tests can and cannot tell us.


So long, Denisova

Eight years ago, I had the privilege to introduce a new word into the New York Times lexicon: Denisovan. I was writing about the discovery of human-like DNA in a fossil tooth in a Siberian cave called Denisova. It represented a new lineage of humans, which the researchers named after the cave.

As the years passed, archaeologists found more Denisovan remains in the cave, spanning over 200,000 years. But they didn’t find any Denisovans anywhere else, despite compelling–albeit indirect–evidence that they lived across much of Asia, and perhaps beyond.

Now, at last, a Denisovan beyond Denisova has come to light. The irony is that the fossil was actually discovered 40 years ago in Tibet. You can read my story about this remarkable development here.

If someone says, “I guess it’s in my DNA,” you never hear people say, “DN—what?” We all know what DNA is, or at least think we do.

It’s been seven decades since scientists demonstrated that DNA is the molecule of heredity. Since then, a steady stream of books, news programs, and episodes of CSI have made us comfortable with the notion that each of our cells contains three billion base pairs of DNA, which we inherited from our parents. But we’ve gotten comfortable without actually knowing much at all about our own genomes.

In 1980, a Buddhist monk in Tibet entered a sacred cave to pray. On the floor, he found half of a human jawbone, studded with two teeth.

A team of scientists on Wednesday reported that the fossil belonged to a 160,000-year-old Denisovan, a member of a lineage of mysterious, Neanderthal-like humans that disappeared about 50,000 years ago.

The fossil is the first evidence of this species found outside the Denisova Cave in Siberia, buttressing the theory that these relatives of modern humans once lived across much of central and eastern Asia.

I held off on the April edition of Friday’s Elk for a couple late-breaking pieces I’ve been working on. Here they are, plus some interesting reading from other writers if you’re looking for something to feed your mind. And be sure to check out the new entries in my speaking schedule at the end of this email. (Even more talks to come!)
