In the rural Rocky Mountains where I live, we disagree about a lot of things — politics, religion, water, Tim Tebow — but we all agree on aspen. We love them, especially when they turn blaze-yellow in the fall, and we’d like them to stick around. So in 2004, when aspen throughout the Rockies started […]

Our boy, AG, is referring to a joke: a dairy farmer asks a physicist how to estimate milk production. The physicist begins the calculations with, “Assume a spherical cow,” and takes it from there. Physicists are famous for this. They call it simplifying the model. Sometimes they have a problem that’s too complicated to be […]
I’ve spent a lot of time this past year thinking and writing about extinction, which means I’ve also spent a lot of time drinking thinking about the tragic narrative in environmental journalism. There’s a lot of genuine tragedy on the environmental beat, and it doesn’t take a partisan to see it. There’s not a whole […]
As far as obscure ecosystems go, the outer edge of expanding sea-ice sheets has got to be near the top of the list. Not algae-living-in-sloth-hairs obscure, I suppose, but then the algae that grow inside the sea ice have a significantly greater impact on just about everything else in the world, other than sloth hair. […]
I probably shouldn’t say this, but I love it when scientists occasionally throw all caution to the wind and clamber out on what seems a visibly shaky limb. Not of course, when they are offering up some new off-the-wall theory on autism or sudden infant death syndrome or flu vaccines—fields in which a little speculation […]
New Yorkers don’t scare easily. They are blasé about crime, absurdly aggressive behind the wheel, and generally indifferent to even the biggest rats. Even vampires don’t inspire fear. I once saw a pair on the N train in Queens, and no one (but me) batted an eyelash. Blood sucking insects, however, are an entirely different […]
Have you ever looked at a chicken? I mean really looked, and not the kind that comes safely shrink-wrapped in a Styrofoam tray? There’s something in the eyes, something still-wild, almost menacing—no, really menacing. Given a little room to move around and enough conspecifics to elicit social behaviors, the animals are aggressive, territorial, and relentlessly […]
In 2000, the last Pyrenean ibex died. These were mountain goat-like mammals with fierce black horns that scampered around the Pyrenees Mountains between France and Spain. Some cells had been taken from that last animal, and in 2009 the world learned that scientists had been able to clone the creature: a Pyrenean ibex kid was […]
