This week's deconstruction
As mentioned on these pages before, Puddinhead is a scientist. It's becoming increasingly obvious [to him, anyways] that so much voting and legislation regarding sciences, particularly the biological ones, are done by the laiety who don't necessarily know what they're talking about. One peril of liberalism these days is the anti-intellectual streak permeating popular culture - hey, it's been with us since Adlai Stevenson. Of course, so has the odd liberal sense that the group is nobly losing, and that as a collective it's getting cut down in battle. In terms of cultural mythology, this is a sort of interesting tack to follow. Unfortunately, we have slightly more pressing matters these days. It is certainly some hubris that accompanies this desire for change - I mean, we're right, aren't we? - that makes it a bit difficult for the self-aware to parse out ego from the demonstrably factual. That's part of the Hamlet idea, no? That it's noble to struggle with self-doubt? By and large, any self-doubt that tortures conservatives is done in private, where it takes such extremes as to be baffling when exposed to the light of day.
Shit, look at even me. I just blew a paragraph handwringing about seeming too arrogant because I think that facts ought to be considered when writing legislation.
Fuck that shit.
Where were we? Ah yes: one of Puddin's colleagues puts it, "More people in this country believe in the virgin birth than believe in evolution."
So let's examine some of the actual science, and underreported facts, behind recent legislative decisions. Today's topic will be stem cell research.
We'll examine some of the promises and blind alleys offered by working with these cell types below. However, the first thing that needs addressing is the conservative rationale for preventing the research. Here's Bush's statement on the matter. For some context, he's talking about how one derives stem cell lines from human embryos. Below, I've highlighted a few passages, emphasis mine:
When doctors match sperm and egg to create life outside the womb, they usually produce more embryos than are planted in the mother. Once a couple successfully has children, or if they are unsuccessful, the additional embryos remain frozen in laboratories. Some will not survive during long storage; others are destroyed.
...
As I thought through this issue, I kept returning to two fundamental questions: First, are these frozen embryos human life, and therefore, something precious to be protected? And second, if they're going to be destroyed anyway, shouldn't they be used for a greater good, for research that has the potential to save and improve other lives?
...
As a result of private research, more than 60 genetically diverse stem cell lines already exist. They were created from embryos that have already been destroyed, and they have the ability to regenerate themselves indefinitely, creating ongoing opportunities for research. I have concluded that we should allow federal funds to be used for research on these existing stem cell lines, where the life and death decision has already been made.
The way in vitro fertilization works, as Bush says, is by fertilizing human eggs from a woman with sperm from a man in a dish. This fusing of two cells divides a few times, just like it would if it were the result of these two cells meeting under more hospitable circumstances [i.e., a womb]. When I say "a few times", I mean 2 or 3 times, for a total of eight cells. When IVF specialists do this for a couple seeking a baby, they tend to collect about seven oocytes, or eggs, and they fertilize them all. To increase chances of implantation [these things don't always take], they tend to put 2-4 embryos into the womb. This means the rate of multiple births in women undergoing IVF shoots through the roof [about 25% of these births produce twins]. Most of this is spelled out in the information page of any fertility clinic you care to visit: try here, here, or here.
However, those of you astute enough to do the math will note that if a woman has seven oocytes fertilized and four of them implanted, three go someplace else. In simple language, the IVF clinics tell you where [this one's from here]:
- Q: What happens to any extra pre-embryos?
- A: A maximum of four pre-embryos will be transferred to the uterus for possible implantation. Patients will have several other options regarding the disposition of the remaining pre-embryos. One option is to freeze pre-embryos for your later use. Other options are to donate or simply dispose of them. Excess pre-embryos, if any, belong to you, and you will determine what is to be done.
Here's where it gets sketchy. Reread Bush's comments. He acknowledges that some of these things are being thrown out, but sort of glosses over it, and instead implies that these days, there won't be any more destruction of innocent embryos. However, it happens all the time. Every day. If you don't want to fill up racks and racks of freezer space at the clinic, you just thaw those four or eight cells out and pour 'em down the sink. If Bush were really after not letting embryos die, don't you think he'd, say, try to make it illegal for fertility clinics to dispose of the eggs? He won't, of course. Then we'd have thousands and thousands of embryos in freezers, waiting for some selfless woman to implant a stranger's baby in her womb.
Instead, Bush's administration allows federal dollars to pay for your IVF treatments, and the subsequent destruction of those embryos should you decide to take that path.
So is the President serious about this culture of life business? Not at all, at least in regards to stem cell research. While these statements of moral weight were made back in 2001, when the country had less serious matters to fret over, we should still recognize that potentially lifesaving research is being profoundly hampered in this country.
Is it potentially lifesaving? How would all this stuff work? I'll address that next post.
