We’re all just slow birds

Next time GrrlScientist comes to visit, we’re going to have to record what she says early in the morning, and then play it back ten times faster — I have a suspicion that we’ll hear birdsong.

At least, that’s the way this video art installation by Marcus Coates works. He had people sing strange little nonsense tunes (you can hear one here) that, when played back at a greater speed, recreated the songs of wild British birds. Why, if GrrlScientist had only talked a little faster, I’m sure the whole house would have sounded like an exotic tropical island inhabited by parrots!

Those savage Humboldt Squid

These stories about the Humboldt squid invasion off the California coast keep turning up — the latest from the San Jose Mercury News is broadly informative, and even cites a fresh new paper in PNAS. The work correlates the depth range of the squid with that of the Pacific hake, and also shows a rough correlation between the squid population and hake declines over a number of years. This suggests that maybe “invasion” isn’t the right word anymore: the Humboldts are new California residents.

The present situation off central California appears to be that
a physiologically tolerant species with a fast generation time
has moved into a new area during a period of substantial climatic,
oceanographic, and ecological changes. The occupation has
lasted through multiple generations of the invading species, which indicates a sustained population rather than a relict one
or multiple invasions. The geographical range of the invader now
extensively overlaps that of a large commercially valuable fish
stock. If this trend continues, top-down forcing could have a
major impact on the most abundant commercial groundfish
population off the west coast of North America. A similar
pattern may also be taking place in the Southern Hemisphere.

As a past resident of both Oregon and Washington states, which have experienced some irritating invasions of Californians, I have to say … now you know what if feels like, nyah nyah.

The authors also suggest that we may not be able to pin this one on global warming. The overfishing of swordfish and tuna have reduced the effects of these predators of the squid, and now they’re experiencing a bit of a population boom, one that means other animals on the food chain are experiencing some new pressures. Ecology is never simple, is it?

The newspaper article reports that people are fishing for the Humboldt squid, and it’s turning up on restaurant menus in the Monterey area (anyone try it? How is it?), and there are charter boats that will take you squid fishing. If I ever get a couple of days in Monterey, I think I’d like to try that.

The ladies already knew about our lack, of course

A correspondent just reminded me of this classic paper from the literature—it’s the only contemporary scientific work I know of that managed to combine a discussion of the induction of a tissue by TGF-β and BMP proteins with a discussion of the Hebrew noun tzela to suggest that the book of Genesis wasn’t talking about thoracic ribs at all. All us sneering atheist professors who’ve had to exhibit human skeletons to show the creationists in our classrooms that men are not missing a rib apparently should have been pointing a little lower — where humans are missing a bone.

This comment on the Panda’s Thumb leads to a very interesting entry on OMIM, the database of human genetic characters. We’re missing something.

OS PENIS, CONGENITAL ABSENCE OF

Deletion of the gulonolactone oxidase gene on 8p21 is a genetic disease that affects 100% of humans. Lack of the enzyme causes severe connective tissue disease and makes humans dependent upon dietary supplements of ascorbic acid; see 240400. Gilbert and Zevit (2001) pointed out that another genetic condition, affecting 100% of human males, is congenital lack of a baculum (os priapi; os penis). Whereas most mammals (including common species such as dogs and mice) and most other primates (except spider monkeys) have a penile bone, human males lack this bone and must rely on fluid hydraulics to maintain erections. The size of the rodent baculum is regulated by the posterior members of the HOXD (142987) set of transcription factors. Gilbert and Zevit (2001) suggested that it was not a costal rib but rather the penile ‘rib’ or baculum that God removed from Adam to create Eve (Genesis 2:21-23). Genesis also states that ‘the Lord God closed up the flesh.’ Gilbert and Zevit (2001) suggested that the raphe on the penis and scrotum was thought to be the surgical scar.

I’m a deformed mutant, a pathetic shadow of my bold, upright ancestors. My only consolation is that all you other guys are, too.

How about waterproof, buoyant pizza?

Having read Mooney’s Storm World last week, I can’t be too disturbed by this bit of news: the pizza man who is fanatically devoted to the pope, Tom Monaghan, is opening his new planned town dedicated to Catholic values next Saturday. There will be no porn or contraceptives available in town, but I hear there will be a whole clinic dedicated to pediatric proctology on Main Street.

Anyway, the town is Ave Maria, Florida. Mooney’s book points out that one of the looming problems from catastrophic storms and global warming is man-made, the growing investment in valuable infrastructure and population in precisely those areas at risk from natural disaster. This gives me an idea: I think the southern coastal states ought to give incentives to religious organizations to build along the shores. Pull back all those merely material and economic developed resources farther inland, and construct wall-to-wall religious enclaves everywhere that we worry about hurricanes instead, as a bulwark against acts of god.

We can’t lose. If they’re right, their prayers and purity will stave off disaster. If they’re wrong, well, no loss to the country if ten thousand churches get inundated.

It also puts a nefarious twist on the closing quote in the story.

Monaghan has said his goal is to help as many people as possible get to Heaven. And he hopes these homeowners will have a head start.
