The shocking truth!

The Schoepenhauer awards are a delectable collection of interesting descriptions of parasites, such as the roundworm.

Today we’ll introduce you to the Intestinal Roundworm, a hideous parasite which infects one out of every four people in the world. That’s not a misprint: one out of four. More than one and a half BILLION people. Yup, every fourth person on this planet is nothing but a travelling worm farm.

Sweeeeet, right?

But hey, do you remember that moment in a certain cult movie when Sean Connery, dressed in little more than bandoliers and a speedo, is rummaging through a library and discovers the truth about his god, the incredible gun-spewing penis-hating flying head named Zardoz? He finds the book The WIZARD of OZ, and realizes he’s been tricked, and his whole life has been a lie, and he has to go kill all the Immortals and sleep with Charlotte Rampling.

Notice any remarkable similarities? Anything that makes you go “hmmm”?

Does this help?

NOOOOOOOOOOO!

I’ve been tricked! Now I have to go home and get a pistol and some red underwear. Somebody…warn Charlotte Rampling, before it’s too late.

News from Enceladus

There were all kinds of rumors today (from Drudge, of all places) that NASA was going to announce some major discovery related to life elsewhere in the solar system. While that would be incredibly cool, I was dubious—anyone remember the Martian “bacteria”? NASA has a rather poor reputation for this sort of thing.

Anyway, Bad Astronomy has the actual news: it’s interesting, but the media blew it way out of proportion. Plumes of water (they think) have been observed on Enceladus, a moon of Saturn.

I’d be more enthused if the earlier hype hadn’t switched on my skeptical gland and flooded my system with cyniclin, the hormone of disillusionment.

Snuppy is a real clone!

Remember Snuppy, the cloned puppy? He’s been living under a cloud for a while now, since one of his creators was Woo-Suk Hwang, the Korean scientist who was found to have faked data and exploited his workers, and there was concern that perhaps the dog cloning experiment was also tainted.

Put those fears to rest. Two groups of researchers have independently analyzed Snuppy and its putative clone parent, and both agree that it is most likely a clone. The nuclear markers between the two were identical, while mitochondrial markers were different—exactly what you’d expect in this kind of clone, and not what you’d see from simple twins, for instance, or if someone had faked the samples.

Hug a high school teacher today!

My morning was spent at the local high school today, talking to the biology classes about the evidence for evolution. This wasn’t in response to any specific worries—in fact, talking to the instructor, it’s clear that they’re doing a decent job of covering the basic concepts here already—but that my daughter is in the class, and she thought it would be fun to have her Dad join in the conversation. I will say that it was very obliging of the Chronicle of Higher Ed to publish this today:

In a packed IMAX theater in St. Louis last month, a middle-school teacher took the stage and lectured some of the leaders in the American scientific establishment. In a friendly but commanding style honed by three decades in the classroom, Linda K. Froschauer told scientists that it was time for them to get involved in elementary and secondary education.

“Go home. Identify science teachers in your own neighborhood. Offer to help them,” she said. “Go to the board of education and speak up.”

Excellent advice! It gives an overworked teacher a brief break, lets you see what’s going on in the classrooms, makes the students a little more familiar with college faculty, and maybe it makes a few of them think and gives them a tiny bit more background. It was generally a very positive experience, although it does make me appreciate the work our secondary ed teachers have to do.

I gave a very informal lecture in which I confronted the whole ‘controversy’ about humans evolving from apes. I brought along a few transparencies and a human skull, and gave them an overview of three lines of evidence: transitional fossils, similarities in genes and chromosome structure, and “plagiarized errors”. I kept it fairly simple, using little of the technical vocabulary and defining what little I had to use, but tried to introduce some important concepts, like the taxonomic hierarchy and diagnostic characters and repetitive DNA and pseudogenes. I was also impressed that the students asked good questions, so I think they were grasping what I was talking about.

Boy, but high school teachers have a very different burden than I do. Having to give the same talk 3 times in a row is challenging—I was getting bored with me! The students also range in ability and interest far more than I’m used to…there were many who were attentive and curious (more than I’d expected, which is a very good sign), and there were some who were bored and rather disruptive (but not as many as I’d feared.) I tried not to completely neglect the troublemakers and engaged them a few times with questions, but I had it fairly easy since the regular teacher was there to hover over them and keep them in line. There’s a bit of drill sergeant rigor required in high school teachers that I don’t need at the university as much, I think.

I’d do it again, gladly…as long as I’ve got a few weeks to recover between days at the high school. The grade schools are where we have the most need to get more science into play anyway, so it feels like a productive birthday for me when I can talk to a few 10th graders. And any high school teachers out there—you’re doing an important job, and those of us up in the ivory tower of the university really do care about what’s going on in our schools. Don’t be shy about asking your local college science departments if we’d be willing to contribute in your classroom, I think there is a fair number of us who’d be happy to share our perspective.

Happy Birthday to me!

Here it is, my 49th birthday, and it’s spring break. My wife’s at work, my daughter is at school, all the students are away, it’s dead quiet around here. How to celebrate? I know! I’m going to do some guest lectures at the local high school!

So that’s where I’ll be this morning, introducing high school kids to the subject of…evolution.
