Are worms gay? If they are, what does that mean for humans? Such questions may sound entirely irrelevant to anything in our lives, but some scientists, including Erik Jorgensen at the University of Utah, have apparently received money to study these questions. The worms—nematodes, really—are tiny, 1-millimeter-long creatures who live in soil. Most are hermaphrodites, which means that each worm produces both sperm and eggs. The Times of London reported that Jorgensen activated a gene in the hermaphrodite worms’ brains, which apparently convinced them to try to mate with other hermaphrodites rather than just with the male worms.
The conclusion, according to Jorgensen’s quote in the Times: “We cannot say what this means for human sexual orientation, but it raises the possibility that sexual preference is wired in the brain.”
Hey, there’s something no one ever thought of before.
This study serves as a reminder that there are only so many research dollars available, and most of it comes from your taxes. Do you want to foot the bill for experiments that don’t have anything to do with preventing or curing illness? Or for studies that are obviously redundant or pointless? Or for experiments that are so cruel that whatever is learned from them simply isn’t worth the cost?
I’m opposed to using animals for experimentation on ethical grounds, and I also believe—as science frequently shows—that most studies on animals aren’t particularly relevant to humans. But even those who support research on animals should be careful about accepting the experimentation industry’s claim that the use of animals in laboratories will help find cures for Alzheimer’s, AIDS, Parkinson’s, cancer and other diseases that are frightening just to contemplate. Consider first what some experimenters get paid big money to do.
In July, Johns Hopkins University announced that it was attempting to create a “schizophrenic” mouse by inserting a gene from the DNA of a human family with schizophrenic members into a mouse. Yet a diagnosis of schizophrenia hinges on the patient hearing voices that aren’t there and seeing things others don’t see. How exactly does an experimenter know if this is true of mice, even if a gene has been inserted?
At Oregon Health & Science University, experimenter Eliot Spindel injects the fetuses of pregnant monkeys with nicotine and then gives the mothers vitamin supplements to see if that makes it “safer” to smoke while pregnant. Yet we’ve known since 1972 that smoking is harmful to human fetuses. Spindel’s money would have been better spent convincing pregnant women not to smoke.
Under the guise of studying fetal alcohol syndrome, David J. Earnest at Texas A&M Health Science Center examined sleep problems in baby rats who were force-fed alcohol. Perhaps Earnest is unaware that human infants don’t binge-drink after birth.
