This morning I noticed that on top of my blog there’s an ad for an upcoming show on the Discovery Channel that claims to reveal the tomb of Jesus and his family. I haven’t seen a preview of the show, and from an article in this morning’s NY Times, I have very little interest in doing so:

The filmmakers commissioned DNA testing on the residue in the boxes said to have held Jesus and Mary Magdalene. There are no bones left, because the religious custom in Israel is to bury archeological remains in a cemetery.

I suspect poking around Conservapedia will become one of my new tools for procrastination. You’re guaranteed a jaw drop within a couple minutes of searching on this Wikipedia for conservatives. It occurred to me that I had not yet bothered to look up “creationism.” The entry is a whiplash of a read, with critics and backers of creationism having it out, sometimes within a single paragraph. What really struck me was the section on “Attempts to Criticize Creationism.” The history page shows that it is authored by “Aschlafly”–presumably Andrew Schlafly, founder of the entire site. It is marked “Don’t delete these changes.”

My ancestry forms a smear across northern and central Europe, a region of the world where many people have a peculiar gift: they can drink milk as adults. Almost all people can digest milk sugar (lactose) as babies, but in many parts of the world they lose this ability after they stop nursing. The change is due to an enzyme called lactase, which breaks down lactose into digestible fragments. Most people stop making lactase as they grow up. If they drink milk, the lactose builds up in their guts, where it can be devoured by microbes that produce gas and other discomforts. (It’s not so unpleasant for such people to eat cheese or yogurt that’s low in lactose or which contains bacteria that make their own lactase.)

Tomorrow I’m heading down to New York to take part in the “Inside Out” speaker series at New York University’s Department of Journalism. John Rennie, editor-in-chief at Scientific American, and I will try to answer the question, “Can two prominent magazine journalists find happiness blogging?” The inquisition, run by LA Times reporter and NYU writer-in-residence Lee Hotz is open to journalism students and faculty. It will take place the fifth floor atrium of 10 Washington Place, at 6 p.m on Tuesday. See you there.

Loyalty, teamwork, cruel deception: welcome to robot evolution.

Living things communicate all the time. They bark, they glow, they make a stink, they thwack the ground. How their communication evolved is the sort of big question that keeps lots of biologists busy for entire careers. One of the reasons it’s so big is that there are many different things that organisms communicate. A frog may sing to attract mates. A plant may give off a chemical to attract parasitoid wasps to attack the bugs chewing its leaves. An ant may lay down pheromone trails to guide other ants to food. Bacteria emit chemical signals to each other so that they can build biofilms that line our lungs and guts.
