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…

Oh gob, the stupidity. The latest wave of anti-choice legislation is based on one trivial premise: it’s got a heartbeat! You can’t kill it if its heart is beating! So stupid bills have been flitting about in the Ohio, Mississippi, Wyoming, Arkansas, and North Dakota legislatures trying to redefine human life as beginning at the…

Science doesn’t say that!

Have you ever noticed how the religious regard ‘scientism’ and ‘reductionism’ and demands for concrete evidence as barely a notch above obscenities? That is, until they need to reduce complex issues to simplistic claims and don the mantle of Science to support their beliefs. Then they become Holy Writ. You can really see this behavior…

Not as much fun as it sounds

This is Hazel Jones. She has two vaginas. She has a condition called Uterus Didelphys. Variations of this condition aren’t uncommon, occurring once in a few thousand births. The reproductive tract develops from paired tubes that fuse prenatally, and sometimes the fusion is incomplete, producing a range of arrangements illustrated below. Would you believe a…

It truly does, and someone has caught us out and published a stunning exposé that reveals the horrible, awful behavior that our goddess, Nature, endorses. You must read “God Hates Checkered Whiptail Lizards!!!” and weep. This is but one page of a devastating revelation. (Also on FtB)

Why do women menstruate?

Menstruation is a peculiar phenomenon that women go through on a roughly monthly cycle, and it’s not immediately obvious from an evolutionary standpoint why they do it. It’s wasteful — they are throwing away a substantial amount of blood and tissue. It seems hazardous; ancestrally, in a world full of predators and disease, leaving a…

Catholic compassion

I guess the Catholic church is concerned about the rights of breast cancer tumors: they probably identify too much with a deadly metastatic disease, and don’t want to seem them hindered. At least, that’s the only way I can interpret the decision of the Toledo, Ohio diocese to ban all support for the Susan G.…

It’s been a rough weekend. It was a rough night, with little sleep. This morning I had the double whammy of a doctor’s appointment and a dentist’s appointment. So I’m feeling a little cranky, and my teeth are all coated with this gummy gritty cherry-flavored fluoride goop. You don’t want to cross me today. And…

Read this horror story of a failed pregnancy. I was taking an afternoon nap when the hemorrhaging started while my toddler napped in his room when I woke up to find blood gushing upward from my body. Though I didn’t know it at the time, I was experiencing a placental abruption, a complication my doctor…

The power of faith

It’s amazing what religion can do. In this case, it motivated some dim old fart who ought to have been loafing about watching Glenn Beck and drowning his anger with a six-pack of Bud to go out and try to murder gynecologists. He didn’t actually succeed, fortunately: he was playing with his gun in his…
