Dry Spells

In the spring of the year 73, thousands of Roman soldiers raided Masada, a fortress on top of a cliff in the Judean Desert. For seven years, the Jews had tried, unsuccessfully, to split from the Roman empire, and Masada was the last holdout. According to the ancient historian Josephus, when the Romans breached Masada’s walls, [...]

Guest Post: The Scientist in the Garden

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 French pumpkin Rouge Vif d’Etampes. I suppose the names don’t have quite [...]

Guest Post: the Nature of Octopuses

There is an old story about a scorpion and a turtle. Variants abound, but the basic tale revolves around an unusually talkative scorpion that asks a turtle for a lift across a river. The turtle refuses at first, fearing the scorpion’s sudden but inevitable betrayal. The scorpion insists, the turtle relents, and the two get [...]

Autopsy of an Aspen

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 [...]

Abstruse Goose: Stop the Massacre

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 [...]

It’s Not (Always) About the Lorax

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 [...]

Krill Thrill: ‘Happy Feet’ and the end of woodland dominance

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. [...]

Triassic Park

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 [...]

Bed Bug Bugaboo

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 [...]

Help Wanted: DIY Dinosaurs

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 [...]
