When Charles Darwin compared the beaks of his finch specimens from the Galapagos, he saw that each had been shaped differently by evolution, depending on the natural history of the island on which that finch made its home. Many evolutionary biologists see life through this natural history lens, and while they are right to declare […]

I’ve been spending a lot of time lately thinking about my bloodlines. Perhaps it’s my impending fatherhood, perhaps I’m just at that age. I’ve been tracing my grandfathers’ heritages back through the Revolutionary War and to the Tudor conquest of Ireland. I’ve planned a trip to Norway, which is my grandmother’s homeland, and hope to […]
This is an updated version of a post that originally appeared in January 2012. I can’t remember why the seed catalogs started showing up, but once they did, I was a goner. If you haven’t ever gotten one, imagine full color photo spreads of produce, like the striped Tigger Melon and and the orange-red lusciousness of […]
The bar in question is inside an upscale Italian restaurant in northern Wisconsin. The men are middle-aged with graying hair and glasses. But they’re both fit. They look like they might spend their spare time sailing. One wears a blue button-down shirt and jeans. The other is dressed in a polo shirt and camouflage shorts. Button Down […]

Why have I been cursed with women who destroy the children in their own wombs?” So complains Hilary Mantel’s fictional version of Henry VIII – and this Sunday marks the date, 477 years […]
We often lament hype in science journalism. But seldom do we worry about underhype – of downplaying the significance of a study. In March, I had reason to worry about this. Just after Nature published a story that I wrote about a massive cancer genetics project, I received an email from my editor: “Should we […]
When Iben Hove Sørensen flew to Ghana for her work with Dansk Ornitologisk Forening, a partner of BirdLife International, she couldn’t help but think about the birds. The passerines that she was headed south to study follow a similar course that her plane took to their wintering grounds–over the Mediterranean, sometimes through cloud-choked skies, for […]
You probably heard about last week’s Nature study on older dads and autism; it got a lot of attention. The basic findings were fascinating but, in my opinion, far less sensational than what most of the news articles would have us believe. The researchers, led by Kári Stefánsson of deCODE Genetics in Iceland, showed that the average 20-year-old man passes on […]
