Old spiders

Two short articles in this week’s Science link the orb-weaving spiders back to a common ancestor in the Early Cretaceous, with both physical and molecular evidence. What we have is a 110-million-year-old piece of amber that preserves a piece of an orb web and some captured prey, and a new comparative study of spider silk proteins that ties together the two orb-weaving lineages, the Araneoidea and the Deinopoidea, and dates their last common ancestor to 136 million years ago.

Araneoids and Deinopoids build similar looking webs—a radial frame supporting a sticky spiral—but they differ in how they trap prey. Deinopoids spin dry fibers that they fluff into threads that adhere electrostatically to small insects; Araneoids secrete glue onto the the strand, which takes less work (no fluffing), and is much more strongly adhesive. The differences are enough to make one question whether there was a single origin of orb weavers, or whether the two groups independently stumbled on the same efficient form of architecture.

Sing along with Cthulhu

Feeling musical this morning? Stephanie Ching sent me links to some lyrics. An old User Friendly cartoon combines Cthulhu, zombies, and brains, and then there’s the unspeakable: this guy has written a song for John Tesh. If anything is going to rouse the sleeping Old Ones that lie in lost R’Lyeh, it’s got to be New Age caterwauling.

Quick! To scrub the thought of New Age Lite muzak out of your brain, Unfogged provides a cure: visualize your scrotum rupturing. Think about epididymitis and Fournier’s gangrene. There, can’t you feel the nightmare ebbing?

Carnivalia, and an open thread

I’ve been very, very bad at keeping up with all the carnivals, so here’s a quick roundup.

As usual, talk about whatever you want in the comments (at last, a place where the Coulter defenders can be evasive with permission!)

Playing hooky in nerdtopia

You may have noticed it was a bit quiet here on Pharyngula yesterday. I took the day off. My daughter Skatje has been away for a few weeks, visiting her sweetie-pie in Kentucky, and we had to make the long drive to the airport and back, so we decided to make a day of it in the big city as long as we were there. I also had to drop by the Big U and sign some papers.

When my boys and I decide to paint the town red, guess what we do? We headed to Dreamhaven Books, Comics and Art, Phoenix Games, Uncle Hugo’s (what is it with the remarkable concentration of geekdom on Lake Street in Minneapolis?), and The Source Comics & Games. After eating lots of Chinese food, we headed to the airport, only to discover Skatje’s plane was delayed.

So we sprawled on the floor of the Humphrey terminal and played Zombies until she arrived. I have discovered that when faced with the shambling horrors, I will roll lots of “1”s, slapping ineffectually at them until they grapple with me and gnaw on my brains. My sons Alaric and Connlann will grab shotguns, fire axes, and grenades and cut a bloody swath through them on their way to the helicopter pad, where they will fly away leaving me in a slowly closing circle of implacable moaning flesh-eaters.

When Skatje finally showed up (she had a fine time with her boy toy, who apparently works in a comic book shop and plays D&D), it was midnight, and we had the long drive home to face…we finally staggered into the house after a long day of nerd decadence at 3AM.

As you might guess, now I’m feeling exhausted and my brains have been repeatedly chewed upon. And you all know what weirdos we are here at Chez Myers.
