pharyngula | July 31, 2006Suddenly, the FDA has decided to allow over-the-counter sales of the Plan B contraceptive. They've imposed an age restriction—you must be 18 or over to buy it—but it's a smart move in the right direction, and it's about time.
pharyngula | July 19, 2006DarkSyde is on the stem cell story, and he uses Neurotopia's summary of the biology.
I just don't understand the other side's argument. Adult stem cells are not a substitute for embryonic stem cells, at least not yet. The anti-stem cell research crowd wants to claim that we don't need ES cells, that AS cells will do everything we need, but they don't think it through. If we want to make AS cells that are functionally equivalent to ES cells, we need to understand ES cells—but they want to deny us the ability to look at ES cells. Furthermore, if we could convert an AS cell line to totipotency…
pharyngula | July 19, 2006Despite Brownback's snowflake stunt and Santorum's insistence that zygotes are persons, the House stem cell bill, HR810, has passed, as have the two inconsequential smokescreen bills that Santorum tossed up. It's going to be interesting to hear Bush's stammered excuses when he vetos it; I'd figure he'd be reluctant to do the veto because it would mean taking undeniable responsibility for an action, something he doesn't like to do, but then I realized he has another out. He's going to blame God for telling him to kill the bill.
I predict that he will make some pious excuse like that when he…
pharyngula | July 18, 2006A reader sent me copy of a letter that will be published in Science this week, criticizing the dishonest tactics of the anti-scientific adult stem cell "advocates" (in quotes because they aren't really science advocates of any kind—they're only using it as an issue to limit stem cell research.) Anyway, it raises the interesting question of who you're going to believe: scientists with expertise in the issues under discussion, or a flunky for Sam Brownback and shill for the religious right?

pharyngula | July 17, 2006I'm taking it easy here in the fabulous Van Dusen mansion, a bed and breakfast where I'm staying tonight, and I thought I'd browse through the stem cell legislation that's being considered in the senate right now. It's strange: one substantive bill has come up from the House, and all of a sudden two more bills have been proposed on the floor of the Senate.
Here's the interesting one. H.R.810: Stem Cell Research Enhancement Act of 2005, proposed by Congressman Mike Castle, a Delaware Republican who isn't too thrilled with Bush's promise to veto his bill, actually does something substantial. It…
pharyngula | July 11, 2006It's July in Minnesota, and you know what that means: bugs. Clouds of bugs. Some people complain, but I generally rationalize a large population of fecund invertebrates as simply a sign of a healthy ecosystem, so yeah, we've got bugs, but it's good for us.
Except for those mosquitoes. It's hard to think charitably of some invertebrates when you're lying in bed at night and you hear…that…high-pitched whine rising as the nearly invisible little blood-sucker buzzes by your exposed flesh. Now, in a discovery calculated to increase my irritation, I learn that the little bastards are singing a love…
pharyngula | July 10, 2006Hard to believe, but check out the source this anti-choicer uses to back up his essay on the callous horror of abortion.
The Onion.
Satire and irony are now officially dead.
The author has a new post up—he still doesn't get it. He's still babbling about the fictional author of the Onion piece getting all those abortions.
It's a marvel. There really are people that stupid out there.

pharyngula | July 7, 2006If you've read this outrageous WaPo op-ed that basically says you can't expect moral behavior from scientists who are glorified baby-killers, you might appreciate this rebuttal at the Give Up Blog. The foundation of the fundiecrat anti-science article is that 1) Hwang Woo Suk was bad, therefore all stem cell/cloning research is tainted, and 2) alternative techniques (most of which they don't seem to understand) and adult stem cells will give us all the answers we need.
Which actually leads into this week's "ask a science blogger" question:
On July 5, 1996, Dolly the sheep became the first…
pharyngula | June 29, 2006I suppose this is a kind of threat—an archaic and quaint threat, but I'm sure some people take it seriously—but the Catholic church has made a strong statement against embryonic stem cell research.
The Vatican stepped up its fight against embryonic stem cell research on Wednesday, saying that scientists involved in such work would be excommunicated.
Cardinal Alfonso Lopez Trujillo, head of the Vatican department dealing with family affairs, said in a magazine interview that "destroying human embryos is equivalent to an abortion... it's the same thing".
"Excommunication applies to all women,…
pharyngula | June 28, 2006
Maybe half of my audience here will be familiar with this problem. You're a man, and you're hauling this massive, ummm, package around in your pants everywhere you go. Other men fear you, while the women worship you…yet at the same time, your e-mail is stuffed to bursting with strange people making friendly offers to help you make it even bigger. It's a dilemma; you think you would be even more godlike if only it were larger, but could there possibly be any downside to it? (There is a bit of folk wisdom that inflating it drains all the blood from the brain, but this is clearly false. Men who…

Some of you may recall a movie of mating slugs I mentioned before…now here's a site with photos of the act.
In case you're baffled, the strange translucent blue sheets hanging down are the interwined penises of the two slugs. Don't they make a beautiful couple?
(Thanks, Craig Clarke! Does your mother know you browse the web for molluscan porn?)
pharyngula | June 26, 2006Here it is, the proof from breast ironing. Simple selectionist models can't explain why human beings would mutilate secondary sexual characteristics and genitalia, therefore god exists. We also know the Christian right is exactly correct: God really does obsess over people's sex lives, and he is a kind of sick pervert who likes to hurt children.
We can also suspect that he's probably male, since testicle flattening, penis knotting, and scrotum binding don't seem to come up often in his prescribed lists of genital abuses.
pharyngula | June 23, 2006I suspect that soon there will be at least one religious person who will claim he converted from atheism who I will believe. The Raving Atheist is getting ripe: he's been ramping up the irrationality for some time now, precessing like a top slowing down, and I expect that soon enough he'll flop over for Jesus. I'm not questioning his sincerity—he is an atheist, all right, and there is no doubt about it—but his sympathies are getting weirder and weirder.
This is not a new development. I've discussed his radical pro-life position before, and now Punkassblog and Amanda bring to my attention his…
pharyngula | June 13, 2006Seed has an interview with Joan Roughgarden, somewhat controversial evolutionary biologist and author of Evolution's Rainbow : Diversity, Gender, and Sexuality in Nature and People(amzn/b&n/abe/pwll). Here's the short summary of her basic thesis:
Joan Roughgarden thinks Charles Darwin made a terrible mistake. Not about natural selection--she's no bible-toting creationist—but about his other great theory of evolution: sexual selection. According to Roughgarden, sexual selection can't explain the homosexuality that's been documented in over 450 different vertebrate species. This means that…
pharyngula | June 7, 2006It's true, he always makes me laugh. It's the bow tie, the strangled delivery (he always looks like he's careful not to open his mouth too much, lest something fly in…or out), and his oh-so-prim-and-proper prudery.
But early in the American epidemic, political values impeded public health requirements. Unhelpful messages were sent by slogans designed to democratize the disease — "AIDS does not discriminate" and "AIDS is an equal opportunity disease."
George, you are a Republican. Vague political slogans that dance around the actual issues without mentioning any vulgar behaviors or body…
pharyngula | June 5, 2006Isn't this so symptomatic of Republican stupidity?
…the FDA released an internal memo showing that one high-ranking FDA official was sincerely worried about adolescents forming "sex-based cults centered around the use of Plan B." Seriously.
The evidence, which may not be relevant to the Bush administration, shows no link between access to Plan B and risky sexual behavior, worse yet "sex-based cults." How Bush-appointed "scientists" come up with such nonsense is a mystery.
If the administration said, "We're morally opposed to emergency contraception," we could at least have a reasonable debate…
pharyngula | May 27, 2006A new Planned Parenthood clinic is opening in Woodbury, a Minneapolis St Paul suburb. It's a small place without a doctor on staff (a PA or nurse practitioner will be available), and it's primarily there to dispense contraceptives and information. No big deal, right? It's a useful service to have available in a community.
So why are people trying to close it down?
Demonstrators from St. Croix Valley Life Care Center will be joined by ones from Pro-Life Action Ministries and other groups from 9 to 10 a.m. Saturday and again Thursday, when the clinic opens, and will aim to shut the clinic down…
pharyngula | May 25, 2006Great stuff from Majikthise,
Pandagon, and
Shakespeare's Sister on this fairly obvious paper (pdf) that argues that the rhythm method kills more embryos than contraceptives. It's straightforward: by avoiding sex during the prime time for ovulation and fertilization, there's a greater likelihood of fertilization occurring when the egg is past its sell-by date…it's increasing the chance of spontaneous abortion and birth defects. The paper is all speculative and philosophical about it all, but there are actually some suggestive epidemiological data that suggest it is true. A study by Jongbloet…
pharyngula | May 23, 2006Hang on, close your eyes, don't click on the "Read on…" link at the bottom of this post; I've put an obscene picture of explicit prurience below the fold. It might arouse you to engage in wild monkey-sex in your workplace, or worse, inspire horrific violence. Don't view it if you are a sensitive person!
Alternatively, if you're wondering what kind of sick, blue-nosed prude would find such a simple and lovely image of a natural act between mother and child offensive, you need look no further than the LiveJournal administration.
