Horwich Wins Lasker Award by Straddling Science and Medicine

NEW HAVEN — Medicine is a divided world. On one side are the doctors, who come face to face with illness each day and try to heal their patients with whatever tools they can get their hands on. On the other are the researchers, who explore the body’s microscopic complexity, never sure whether their discoveries will ever end up in the hands of the doctors.

Dr. Arthur Horwich, a medical geneticist at Yale University, lives in both worlds. “I’ve always been on the fence between science and medicine,” he said. “I could never make up my mind.”

Ignorance Is No Comfort

Dear Art—

Is Contagion a public health campaign? I don’t think so. The Centers for Disease Control didn’t produce it; Hollywood did. It’s a movie—but it’s a movie for which the creators talked to people who actually deal with viruses and epidemics. And for that, I give them a lot of credit. It’s rare to find a movie that tries to show what scientists actually do, rather than putting an actor in a lab coat and having him fight bug-faced aliens.

On Slate–Contagion: A dialogue about movies, viruses, and reasonable fear

Posted on by Matt Kristoffersen

Last year, while I was working on a profile for the New York Times of a virus hunter named Ian Lipkin, he told me he was consulting on a Hollywood movie about the outbreak of a new pathogen. Kate Winslet would be an epidemiologist. Lawrence Fishburne would work at the Centers for Disease Control. He was hanging out with Gwyneth Paltrow. The director was Steven Soderbergh.

I had a hard time picturing all this.

The Verge of Human

Posted on by Matt Kristoffersen

If you were this man, you’d be smiling too.

The man is Lee Berger, a paleoanthropologist at the University of Witwatersrand in South Africa. He’s holding the skull of Australopithecus sediba, a 1.98 million year old relative of humans, otherwise known as a hominin. In April 2010 Berger and his colleagues first unveiled the fossil in the journal Science. As I wrote in Slate, Berger argued that A. sediba was the closest known cousin to our genus Homo. Hominins branched off from other apes about 7 million years ago, but aside from becoming bipedal, they were remarkably like other apes for about five million years. Among other things, they were short, had long arms, and had small brains. Berger and his colleagues saw in A. sediba what biologists often find in transitional forms–a mix of ancestral and newer traits. It has Homo-like hands, a projecting nose, and relatively long legs. It was intermediate in heigh between earlier hominins and the tall Homo. And it still had a small brain and long arms. (In August, Josh Fishman wrote a feature for National Geographic on A. sediba, complete with excellent reconstructions.)

Climate Relicts: My new story for Yale Environment 360

Posted on by Matt Kristoffersen

I’m among the 800,000 people in Connecticut without power thanks to Irene, so I won’t be blogging much for the foreseeable future. But before I get to other matters like dragging branches around, let me point you to my latest piece for Yale Environment 360. I take a look at a new concept called the climate relict. Around the world, there are pockets of plants and animals living hundreds of miles away from their main species ranges. They were left behind in refuges at the end of the last Ice Age, as others moved towards the poles in response to the warming climate. As the climate now warms even more, climate relicts have a lot to teach us about how to manage biodiversity. Check it out.
