Pathways to sex

I was talking about sex and nothing but sex all last week in genetics, which is far less titillating than it sounds. My focus was entirely on operational genetics, that is, how autosomal inheritance vs inheritance of factors on sex chromosomes differ, and I only hinted at how sex is not inherited as a simple…

I had known that Jérôme Lejeune was the fellow who had discovered that Down Syndrome was caused by trisomy of chromosome 21, but it seems there were many other things about him I had not known — he was just a name. But there were a few things that set me aback. Lejeune became not…

The reification of the gene

Razib Khan poked me on twitter yesterday on the topic of David Dobbs’ controversial article, which I’ve already discussed (I liked it). I’m in the minority here; Jerry Coyne has two rebuttals, and Richard Dawkins himself has replied. There has also been a lot of pushback in the comments here. I think they all miss…

Higher order thinking

The one thing you must read today is David Dobbs’ Die, Selfish Gene, Die. It’s good to see genetic accommodation getting more attention, but I’m already seeing pushback from people who don’t quite get the concept, and think it’s some kind of Lamarckian heresy. It’s maybe a bit much to ask that the gene-centric view…

Remedial reading for big-time scienticians

I don’t understand how this happens. You’ve got a good academic position. You’re bringing in reasonable amounts of grant money. You’re publishing in Nature Genetics and Nature Structural and Molecular Biology. And you don’t even understand the basic concepts in your field of study. For instance, here’s a press release titled “Cause of genetic disorder…

How to make a funny-looking mouse

I’m going to tell you about a paper that was brought to my attention by some poor science journalism, so first I have to complain about the article in the Guardian. Bear with me. This is dreadfully misleading. Though everybody’s face is unique, the actual differences are relatively subtle. What distinguishes us is the exact…

microRNAs and cancer

I’m trying to raise money for the The Leukemia & Lymphoma Society, and I promised to do a few things if we reached certain goals. I said I’d write a post microRNAs and cancer if you raised $7500. And you did, so I did. I kept my clothes on this time, though, so here’s a…

This cat is going to be insufferable

This cat is going to be insufferable You may have heard we’ve got this satanic feline padding about the house now, getting into mischief — she has discovered my collection of cephalopodiana, and her favorite toy is one of my stuffed octopuses that she wrestles and bats around the floor. It’s like she’s rubbing it…

I know you’re thinking we’ve had more than enough discussion of one simplistic umbrella hypothesis for the origin of unique human traits — the aquatic ape hypothesis — and it’s cruel of me to introduce another, but who knows, maybe the proponents of each will collide and mutually annihilate each other, and then we’ll all…

Do the creationist shuffle and twist!

Don’t you hate it when you get up in the morning and the first thing you read on the internet is that the news that your entire career has been a waste of time, your whole field of study has collapsed, and you’re going to have to rethink your entire future? Happens to me all…
