Barcoding Bushmeat

I’m beginning to think that my LWON byline should read: Virginia Hughes, the one who writes about obscure applications of DNA testing. First there was the story about the scientist who found a rare DNA blip that could prove that the corpse in Napoleon’s tomb really is Napoleon. Then there was the team that screened […]

Searching for Jim Gray

Re: Heather’s post on people who’d lost people in recent, godawful earthquakes and found them again via Google technologies.   I’d watched another high-tech-mediated search and though it doesn’t really bear thinking about, I’ll tell you anyway. On February 1, 2007, I got an email from an astronomer named Alex Szalay saying in case I hadn’t […]

An Argument About Crows

“Light thickens, and the crow makes wing to the rooky wood.”  MacBeth is talking, telling his wife it’s a good night to murder the king.  Even a century earlier, the collective noun was “a murder of crows.”  Three centuries later, a poet watches a horse that’s been shot: “gorged crows rise ragged in the wind.  […]

The Emperor and the Parasite

The emperor had grown tired of the Central Asian nomads who routinely swept into his villages, stealing the grain, making off with the women and burning the houses. Wudi realized he needed better, faster horses to […]

Out of the Circus, Under the Microscope

Fleas suck. They also bite. But feeding strategies and a millennia-spanning role in the spread of disease and misery aside, the parasitic insects also happen to be quite remarkable little biomechanical machines. The very definition of minuscule, these wingless wonders can easily jump 100 times their own body length, a skill that scaled to human […]

Talk to the Animals

For animal lovers, there may be no one more heroic than Dr. Dolittle, the title character of Hugh Lofting’s charming children’s books and Richard Fleischer’s schmaltzy movie (one of my childhood favorites). Dolittle’s patients are people, at first, until they get fed up with his growing number of house pets — rabbits, mice, pigeons, a […]

Freeman Dyson: It’s Complicated

What an odd-looking person this Freeman Dyson is.  His nose is long, his ears stick out, his smile is tentatively friendly, but what to make of those eyes? Dyson is hard to describe:  he’s not like anyone you’ve met before and whatever he says is not what you’ll expect him to say.  He’s spent his […]
