Genetics of autism: is it safe to marry an engineer?

http://xkcd.com/c289.html

from xkcd.com

A few months ago, I dreamed that I attended a cocktail party, where I mistook Simon Baron-Cohen (the neurobiologist) for his cousin Sacha Baron Cohen (better known as Borat). I don’t know why either of them was in my dream (I haven’t even seen Borat), but if the opportunity ever comes up, I would like to pick the neurobiologist’s brain over cocktails. I don’t know quite what to think about his suggestion that autism might be caused by assortative mating among technogeeks – not to mention the bit about men and women having differently abled brains.

The famous Rotating Snakes illusion

I was in the subway yesterday when the repeating pattern of concrete blocks started messing with my head. I did a little research later, but couldn’t find anything about the illusion I experienced (probably because I can’t describe it well enough to Google it).

So I’ll just pass on this link from Dark Roasted Blend, collecting some of the best visual illusions out there. You’ve probably seen a few of them, like the rotating snakes, but I doubt you’ve seen all of them. (My favorites are the ladybugs and the spinning dancer.)

Aesthetic outsourcing: arthropod artisans

Peacay just let me know about this cool article in Cabinet Magazine, written by Jeffrey Kastner.

The aquatic caddisfly constructs a shell-like “case” for itself out of debris in its environment. For years, artist Herbert Duprat has been supplying his caddisfly corps with top-grade building materials, and they’ve produced “art” like this:

duprat2.jpg

Is the caddis worm’s precious case the work of the insect or the work of the artist? This is not the right question. The contradiction can be resolved by the differing viewpoints. According to the first view, the caddis worm owed nothing to the artist (who is simply the author of one noise among the thousands of other noises in its environment). According to the second view, the caddis worm is merely the executor of the artist’s project. The artistic statement plays on the confusion of the two levels by overlaying the two perspectives. (Christian Besson, quoted by Jeffrey Kastner in Cabinet; Besson’s extended interview with Duprat in this article from Leonardo)

There’s even a video of a caddisfly case in progress, with the larva perched like Smaug on a huge heap of gold and pearls, scrabbling and gluing away.

I used to collect caddisfly larvae in streams, although I hadn’t thought about them in years. I think the mica-faceted blue-grey caddis-houses of the Pacific Northwest are every bit as beautiful as these baroque arthopod Versailleses. Still, it’s a cool idea – and far better than roach-brooches! (Those overhyped roaches don’t even do the decoration themselves. Pshaw.)

Thanks Peacay!

The End of Jane

Apparently Conde Nast has pulled the plug on Jane Magazine.

I’m depressed. Jane was trash, but always amusingly, smugly arch in its trashiness. The result was a sometimes disorienting pastiche of fashion, gossip, and quirky cultural surprises. Case in point: the June/July 2007 issue of Jane put Dorothy Sayers’ Gaudy Night on its summer bookshelf! I doubt the word “bluestocking” has ever been used in Cosmo or Glamour, much less with approbation!

In its trendy, smart-girl snarkiness, Jane was a spiritual successor to Sassy, which I devoured in middle school (both were created by Jane Pratt; her departure from Jane appears to have led to its eventual demise). It was pure mind fluff – I looked forward to my Jane fix even more than the arrival of the high-maintenance, “read me or be uninformed” New Yorker. My friends won’t understand this, but I’ll miss you, Jane.

Lakewold

a girl
whose hair is yellower than
torchlight should wear no
headdress but fresh flowers

-Sappho (translated by Mary Barnard)

I’ll be traveling for the next three weeks, so posts will be sparse. But I’ll be on the lookout for things to share – like this counterpoint of art and nature, from a visit to Lakewold Gardens, about an hour south of Seattle.

Enjoy the sunshine, wherever you are.

My physics envy: derailed by pesky exponents

Earlier, it seemed like everyone in the biology blogosphere (including me) voiced their opinion on whether biology is perceived to be easier than physics, and whether that explains why we see so much inaccurate popular biology perpetrated by non-biologists. It turns out SCQ explored the physics envy issue way back in 2005, in an article they have just reposted. They reveal the shameful truth: all biologists really want to be physicists! We’re just not good enough at math:

Russell[6] documented the now well-accepted finding that biologists rarely use integers per se, particularly when making chemical solutions. When they believe themselves to be unobserved, biologists prefer to use their own unique counting system consisting of the following quantities:

1. Some.
2. A bunch.
3. A whole bunch.
4. All of it.
5. See if somebody else has any.
6. We’ll have to buy some more.
7. Let’s write a new grant.

These quantification terms are roughly delineated by increasing powers of 10. The biologists’ counting system was compared to the primitive counting system used until quite recently in Samoa.

In my case this is sort of true. I’m not good at math. I wish I was better at it. One of my undergraduate professors told me I would be humiliated in graduate school for being so bad at math (I was humiliated, but for other reasons). And he was just the last in a long line of instructors to denigrate my talents in that area, starting with Mr. Florence in 6th grade – who made fun of me for not being familiar with exponents. Plus, I was not supposed to be good at math – or so I was told – because I was a girl. (Apparently both penis envy and physics envy were unavoidable).

All of this led to an overwhelming dislike for math, which remained intact until I discovered that, despite my gender, physical chemistry is actually kind of cool, and partial derivatives are downright neat-o. Unfortunately that was my senior year of college – a bit late to switch fields.

So who knows? If my 6th grade math teacher hadn’t been an insensitive jerk, or if I hadn’t been fed the girls-are-bad-at-math line so often, I might have become a physicist instead. If so, in the grand tradition of Schrodinger, I would no doubt have eventually started spouting off about biology. When it comes to curious minds, I think the grass is always greener. Not that I know botany or optics. Or psychology.

But I wish I did.

A batch of biology education links

The Science of Addiction
Time Magazine
Graphic by Fielding Cage and Joe Lertola

• Time currently features a solid non-specialist article on the biology of addiction, including some nicely executed web graphics showing brain structures (above)

• These little “Brain Briefings” from the Society for Neuroscience are suitable for non-specialists or students. . . or as refreshers for we neurobiologists who’ve forgotten things we ought to have retained. (Bad brain! Naughty, lazy hippocampus!) (Via Madam Fathom)

• MIT OpenCourseWare | Literature | Darwin and Design

As if I didn’t have enough things to read (that means you, O reproachful pile of Sciences and New Yorkers), MIT has posted the content for many of its courses, including this one.

• Nature’s Milestones in Development series

I used these when I taught developmental biology.

A non-trivial trivia question

Dear readers, I’m in need of advice.  I love Trivial Pursuit, but I have the original questions long memorized (long live Avery Brundage!), and some of my friends have the same problem with subsequent Genuses. When I went online to buy the newest edition of the game, unhappy reviews said the questions have been dumbed down significantly in recent incarnations.

I want something hard, preferably harder than the original, that’s NOT mostly pop culture. I’d rather strain my brain recalling presidents and Nobel Prize winners, not what color Madonna’s hair was in Desperately Seeking Susan.

I do like Cranium, but I want something that works well in small groups. Any other ideas – either for good editions of TP, or for other games?

Wellcome Medical Image Library

The Wellcome collection of medical images has been made available for non-profit use under a Creative Commons license. This is a really fabulous resource. Just for fun I searched “trepanation” and got nine images like these:

Thanks to Stranger Fruit for the heads-up (oops, no pun was intended).

Also of interest: 43 submissions to the Worth 100 medical anomaly competition (via Boing Boing).

Memento mori: cadavers in the classroom

bodywork.jpg

The LA Times recently reviewed Body of Work: Meditations on Mortality from the Human Anatomy Lab, a memoir by medical resident Christine Montross. I’ve been trying to decide if I want to read it, and I’m still uncertain. Although a relative novice when it comes to medicine (my degree is in molecular biology), I taught anatomy using human cadavers, and have dissected them. I never found cadavers the least bit disturbing. But I may be unusual in my detachment – my students reacted with disgust, distress, nervousness – and constant anxiety that their reactions weren’t normal.
