The Last Word

August 27 -31 This week, guest poster Anne Casselman reported on a fascinating group of new experiments that indicate that a real solution to climate change won’t come from engineering better biofuels as much as it will come from engineering better ways to exploit our own psychological trap doors. After all, social pressure is our […]

Top 3 Reasons to Stop Fretting About Being an Old Dad

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 […]

The Last Word

July 30 – August 3 I was wrong. It looks like you can expect a penis every Friday, thanks to the wild popularity of LWON’s Penis Fridays. This week, guest poster Erik Vance tackled dolphin penises. No, he didn’t. But he explained them to us. Ginny and Michelle reopened the case of whether it’s ever […]

What Americans Don’t Get About the Brain’s Critical Period

The meeting featured eight-minute presentations from experts in public policy, education and child development, and […]

Galápagos Redux: When Is It OK to Kill Goats?

Two weeks ago, I wrote about scientists who intentionally killed 80,000 feral goats on one of the islands in the Galápagos archipelago. The effort was in the name of biodiversity and conservation, sure, but was it right? The post spurred some fascinating questions and comments, particularly from Jason G. Goldman, who writes The Thoughtful Animal […]

The Last Word

July 23 – 27 Penis Friday got violent this week with Brooke Borel‘s guest post about the bedbug penis, whose shape makes me freeze in terror. They use this thing to engage in what researchers call “traumatic insemination“. Aw, and bedbugs used to be so cute, too. Speaking of dicks, turns out Walt Whitman was […]

Galápagos Monday: The People Problem

This is the last installment of my six-week series about the Galápagos Islands. To recap the first five posts: The Galápagos is an archipelago of 14 volcanic islands that scientists since Darwin have gone well out of their way to study. The islands are extremely inhospitable to life, and yet, over long periods of time, life has […]

Galápagos Monday: When Conservation Means Killing

Judas knew what he was doing when he double-crossed his friend Jesus. “What will you give me if I betray him to you?” he asked the conspiring priests in the famous Bible story. The story of the Judas Goat is more tragic. She had no idea that she was leading her friends to their deaths. […]
