Speaking of genetics, this is the week the results from our big triple point cross (it’s a kind of mapping cross where we determine the distances between three different genes) come rolling in. It’s always a bit nerve-wracking for me, because this is the first time these students have worked with flies, it involves a series of crosses with multiple points where they can screw up, and if they all messed up, we don’t have enough time in the semester to repeat it. So every week I go into the lab, and there are students who are staring confusedly at their bottles, and wondering if they did something wrong, and telling me they are are afraid they might have added males of the wrong phenotype, or they have confused which generation is which, or things are just addling their brain and they can no longer understand what they are doing.

And my job is to puzzle it all out, or figure out how we can test and make sure they’ve got the right flies, or to explain everything to ease their addlement. This is a simple experiment, but with a mob of novice Drosophila geneticists the natural condition is one of insurmountable obstacles on the road to imminent disaster. Every time. I feel a bit like Philip Henslow in this clip from Shakespeare in Love all semester long.

And he’s right! It does turn out well in the end, for mysterious reasons that always puzzle me. They’ve started turning in the numbers from the first few groups who are ready, and they’re pretty much what I expected, and there are no major anomalies, and everyone did every single one of the crosses correctly (major errors would lead to obviously and sharply different results, so I can tell). I think we can just trust the students to try hard to do everything right.

Now they just have to analyze the data and write up a formal lab report. Where is the report? Oh, it’s coming. It’s coming.

Robert Dillon teaches genetics at the College of Charleston…or rather, he is officially assigned the job of teaching genetics, but one might question whether his students are actually learning anything. He’s tenured, but is currently suspended from teaching over a dispute about his syllabus that has snowballed into a mess of a case.

I started reading this article with some sympathy for Dillon. I teach genetics, too, and I’ve been teaching it almost as long as he has. I’m a little bit demanding in the classroom — this is conceptually difficult material for many students, and you can’t lead them by the hand through every step of figuring out every problem, and at some point the students have to figure out for themselves how to do the work, or they haven’t succeeded in being independent thinkers. I also get annoyed at some of the dictates from on high, where we are told to fit our work to a template designed by people who don’t teach our classes. I can feel for his resentment.

But we also have a job to do. It looks like he’s not doing it.

I know! It sounds so official and sciencey! It’s got “college” in it, which is formal and academic, and “pediatricians”, which are a kind of doctor, and you can never go wrong slapping “American” on your brand label. But they are a lie.

It’s also because the ACP is not a legitimate medical organization; its name is designed to be mistaken for the American Academy of Pediatrics, which is a national organization with some 60,000 members. The ACP, by contrast, is estimated to have no more than 200 members, and it has been designated a hate group by the Southern Poverty Law Center for its anti-LGBT positions.

“The American College of Pediatricians urges educators and legislators to reject all policies that condition children to accept as normal a life of chemical and surgical impersonation of the opposite sex,” the statement reads. “Facts – not ideology – determine reality.” The “facts” that follow actually reflect a social conservative ideology that rejects the very reality of what transgender children experience.

They’ve issued a statement that transgender kids are being harmed, based on claims that believing you are of a gender other than the one you were born with is a mental disorder (psychologists disagree), that it’s just a phase kids go through (nope, again — that’s based on some bad studies), and that sex reassignment surgery, rather than discrimination and hatred, triggers suicide at a high rate (you can figure that one out).

I’m all in favor of facts. Unfortunately, painting the word “fact” on a lie does not make it true.

This is a Minke Whale, in life.

Unfortunately, it’s going to be a little harder to see them in life. The Japanese whaling fleet has just returned to base with a lot of carcasses that will be destined for cans and pet food.

Japan’s whaling fleet has returned to base with the carcasses of 333 minke whales, in apparent violation of a ruling by the International Court of Justice.

Reuters quoted a statement by Japan’s Fisheries Agency that said 103 male and 230 female whales were caught during the fleet’s summer expedition to Antarctic waters. Ninety percent of the mature females were pregnant.

Did you know that Japanese whaling was banned by the International Whaling Commission, with one little loophole left for scientific research? They’ve been abusing that loophole for years.

The court said the research program had generated only two peer-reviewed papers that together refer to nine whales.

‘In light of the fact that [Japan’s program] has been going on since 2005 and has involved the killing of about 3,600 minke whales, the scientific output to date appears limited,’ the court wrote in its judgment.

By a 12-4 vote, the court based in The Hague decided Japan must ‘revoke any extant authorization, permit or license granted in relation to’ its whaling program, ‘and refrain from granting any further permits’ related to it.

The Roaming Ecologist has a few words about lawns.

Lawns – those myopically obsessive (and evil) urban, suburban, and increasingly rural monoculture eyesores that displace native ecosystems at a rate between 5,000 and 385,000 acres per day* in favor of sterile, chemically-filled, artificial environments bloated with a tremendous European influence that provide no benefits over the long term; no food, no clean water, no wildlife habitat, and no foundation for preserving our once rich natural heritage. And there’s the unbearable ubiquitousness of mowing associated with such a useless cultural practice, which creates a ridiculous amount of noise pollution, air and water pollution, and a bustling busyness that destroys many peaceful Saturday mornings. The American lawn is the epitome of unsustainability.

I would like to subscribe to your newsletter, and attend your weekly meetings protesting grass, rather than mow my lawn. That season is soon upon us.

But then he also shares this excellent illustration of native prairie plants. They’re all roots! Unlike that scrubby shallow Kentucky bluegrass film on the left, that just forms a superficial mat of roots.

OK, now what can I do to kill the ground hugging parasites covering my yard and replace them with cool plants like that?
