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…

Crazy, obsessed, weird, perverse

Sometimes those are good descriptors. I read a happy story for a change this morning: it’s about Arunachalam Muruganantham, an Indian man who embarked on a long crusade to make…sanitary napkins. Perhaps you laugh. Perhaps you get a little cranky at a guy who rushes in to meddle in women’s concerns. And there’s some good…

I was rather surprised yesterday to see so much negative reaction to my statement that there’s more to evolution than selection, and that random, not selective, changes dominate our history. It was in the context of what should be taught in our public schools, and I almost bought the line that we can only teach…

Demonstrate calmly for pro-science

Brianne writes fairly frequently about her experiences as a clinic escort, dealing with shrieking fanatics who stand on sidewalks harassing people going into family planning clinics. They’re hideous and awful and have lost all sense of perspective and humanity, and they’re also remarkably ineffective…unless, of course, their goals are to make other people miserable and…

Chemists can, sometimes, do pretty work

One of the advantages of working at a small university that puts a variety of disciplines cheek-by-jowel in a single building is that I get exposed to all sorts of different stuff. It sometimes has its downsides — I’m on an interdisciplinary search committee, so next week is consumed with seminars in statistics and computer…

Frugal to the point of vacuity

What does it take to get Carl Zimmer to review your research in the New York Times? I suppose it helps to be at Harvard. It also helps to have a combination of subjects — evolution and the human brain — that Zimmer has written about in the past. It helps to have a paper…

A cautionary note about fMRI studies

I’ve been distracted lately — it’s end of the world semester time — and so I didn’t have time to comment on this recent PNAS paper that reports on dramatic sex differences in the brains of men and women. Fortunately, I can just tell you to go read Christian Jarrett, who explains most of the…

Consider it your morning meditation. Or an opportunity to learn something about cell motility.

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…

I am not a fan of the convergent evolution argument for humanoid aliens. I can well believe that it’s likely that intelligent aliens exist out there in the universe, but I’m not even going to try to predict what they look like: there are too many alternative paths that are possible. But for some reason,…
