Mollusc vs. Annelid

We had some rain overnight, and this morning the sidewalk on my way to work was swarming with earthworms and slugs. The slugs here in Minnesota are tiny little pathetic things, unlike the lovely behemoths I grew up with in Washington state, but they’re still cool to see. Anyway, Afarensis led me to this short photoessay about what happens when a hungry slug meets a worm. I am not surprised at all: I’ve seen a few cannibalistic slug feeding frenzies in my time. They’re like the slo-mo sharks of the damp undergrowth.

Yet another timeline

The true history of the world is told in the movies, so obviously what we need is a compilation of movie events to see what was really going on. It’s a work in progress, so there are a few gaps—the period between 1 zillion BC and 65,000,000 BC is a bit sparse on information—but more recent events are better covered. For instance, the year of my birth was quite busy:

1957 New Zealand – Lionel Pritchard and his girlfriend Paquita battle a horde of zombies (Braindead)
Camp Crystal Lake, New Jersey – Jason Voorhees drowns (Friday the 13th)
Michael Myers born (Hallowe’en)
Lana Turner meets Johnny Stompanato (L.A. Confidential, 1997)
The Iron Giant
October Sky

Zombies, supernatural mass murderers, and giant robots…oh, yeah, I remember that. The late 1950s were rife with alien invasions and mutant monsters, too. Lana Turner is a little out of place, until you realize it’s also the year my wife was born.

Evolving spots

Here’s what seems to be a relatively simple problem in evolution. Within the Drosophila genus (and in diverse insects in general), species have evolved patterned spots on their wings, which seem to be important in species-specific courtship. Gompel et al. have been exploring in depth one particular problem, illustrated below: how did a spot-free ancestral fly species acquire that distinctive dark patch near the front tip of the wing in Drosophila biarmipes? Their answer involves dissecting the molecular regulators of pattern in the fly wing, doing comparative sequence analyses and identifying the specific stretches of DNA involved in turning on the pigment pattern, and testing their models experimentally by expressing novel gene constructs in different species of flies.

Good ol’ MnGOP

You really must take a look at the Republican Party of Minnesota Permanent Platform. It’s full of interesting goodies.

There are 19 items in the section on civil rights: ten of them are various permutations of “NO ABORTION!”; two are against gun control; one is to protect people from being forced to join labor unions; one promotes the public display of the Ten Commandments; and one is a commendable condemnation of torture and slavery, but with an annoying qualifier.

Condemning religious, political and ethnic persecution in any country, specifically the
oppression, slave labor, torture and murder of religious believers.

I guess oppression, slave labor, torture and murder of the godless warrants only a “meh.”

There’s also the usual insistence that marriage is between a man and a woman only, there shouldn’t even be civil unions or any legal equivalent between same-sex couples, and a new one to me: they want a “Covenant Marriage” option…as if fundamentalists weren’t more prone to divorce than many of us others.

Here’s the one that really gets me, though.

Protecting educators from disciplinary action for including discussion of creation science, adopting science standards that acknowledge the scientific controversies pertaining to the theory of evolution.

There isn’t anything in there about improving science education, or even an acknowledgment of the importance of science; just this lame stance excusing bad teachers for peddling nonsense in the classroom. It’s official. It’s in the state party platform. Minnesota Republicans are creationists.

Paternal pride

My daughter has posted her ACT scores (if you don’t know what they are, they’re an exam high school kids take; here’s an explanation of the scores). She did very well, especially considering that she took them a year earlier than most kids do. She’s a sophomore in high school, and she wants to go to UMM full time next year, taking advantage of our state’s PSEO program. She’s going to be a full-time college student at the age of 16.

I knew she could do it. I just told her that if she kept her grades up and did well on the exams, I wouldn’t take her to the Purity Ball. What a great motivator for smart young ladies!

They’ve got smellier stuff than we do, too

We biologists think we’re all grody and cool with our dead mice, but then some smart-aleck chemist has to go trump us all with thermite explosions. That just isn’t fair.

Just wait. Now some physicist is going to come along and make us all envious with his homebuilt laser.

Hold it! I just had a brilliant thought! If we got a physicist, a chemist, and a biologist together, we could make a laser-triggered thermite mouse trap. That would be waaaaaay better than a glue trap.
