Today a team of scientists offer a new way of thinking about the environmental fix we’re in. In the words of one of the scientists, we’re driving around on a mesa in the dark with the lights off and without a map. We may fall off the edge of the mesa before we realize where the edge was.

The scientists argue for a safe operating space for the planet, which they propose should be bounded by limits on the carbon dioxide in the air and other factors. That way, we’ll stay away from dangerous thresholds and be able to pass on a healthy planet to our children. Continue reading “Apocalypse Via Press Release” →

Congratulations to all the Macarthur genius grant winners announced today. Their ranks include two evolutionary biologists.

1. Beth Shapiro, at Penn State, studies ancient DNA to understand extinct critters like mammoths and dodos. I’ve embedded a lecture I saw her give over the summer below. [Update: Sorry, sorry–Penn State, not Penn!]

Another winner is Richard Prum from Yale, who I had fortuitously asked to come talk to my writing class this morning. I had my students interview him for a profile. Voila, instant news hook!

The poor students. They were overwhelmed by the torrent of work Prum described, from the sophisticated optical properties of bird feathers to the origin of birds among the dinosaurs to the deep unity of biology and aesthetics. I’ve embedded the Macarthur’s video of Prum from their 2009 Fellows site, where he talks a bit about his stuff.

I’ve been thinking a lot about bedbugs recently, because…well, because that’s part of my job description. I was asked to be on a radio show a couple weeks ago to talk about the rising tide of bedbugs in the United States (note to self: don’t pick up old mattresses left out on trash day). But I also think they’re pretty interesting. (Traumatic insemination, for starters…) And, thanks to Alex Wild, Annie Liebowitz to the arthropods, I now also think they’re rather lovely. If you haven’t checked out his blog, do.
