Stem cells
Playing God
Bush's bioethics czar Leon Kass wants to criminalize lifesaving medical research as violating the natural order of things. Would he have opposed wiping out smallpox?
In August, President George W. Bush appointed Leon Kass to head his Council on Bioethics, which is set to tackle such hot-button issues as stem-cell research, cloning, human genetics and longevity. The selection of Kass, a University of Chicago philosopher, is not good news for those who are sick from or dying of a disease that might be cured with embryonic stem-cell therapy. Kass, who believes that it may not be natural for humans to live so long in the first place, opposes the treatment, and in his current post he is prepared to criminalize the most important research of the century.
Scientists around the world are virtually unanimous in their belief that cloning human beings is a bad idea. The kinks need to be thoroughly worked out — with animal research — before human cloning can even be contemplated. It took almost 300 attempts to clone Dolly the sheep, and the failures were sad and unpredictable. Researchers, uninterested in repeating those failures with higher stakes, tend to agree, therefore, that doctors should not by allowed to implant cloned human blastocysts for the purpose of creating pregnancies.
In other words, scientists — being rational people — would prevent human cloning by corking up the essential bottleneck: pregnancy. This is why they have worked out protocols designed explicitly to prevent the implantation of a blastocyst into a womb.
But these protocols are not good enough for Kass, who maintains that we must quash any science, regardless of its utility or application, that might lead to human cloning. He is particularly worried about a procedure called nuclear transfer, an essential technique in both reproductive and therapeutic cloning. In this procedure the DNA is removed from an egg, and the DNA of the donor is substituted. The egg cell divides, creating a small clump of identical stem cells that could be used therapeutically to cure diseases as diverse as cancer, heart disease, Alzheimer’s and diabetes, among others.
Kass is worried that we won’t be able to control these blastocysts once they’re created. And he is right; the procedure could be performed by any qualified technician. But this is a free country, which means we don’t ban something that isn’t inherently bad merely because it might lead to something bad. This concept is at the heart of the Ninth Amendment. For instance, Americans should not run over people with their cars, so we passed a law against it. But even though it is simple to run people over and no one can prevent it, we still let people drive. And we still arrest them when they run people over.
Kass is suggesting that we condemn hundreds of millions of people to misery, suffering and early death in order to prevent something — human cloning — entirely unrelated to their circumstances. And yet no creditable scientist is proposing to clone a human. In fact, researchers are furious with the handful of renegade scientists who are trying to clone humans; it taints their own honest efforts.
The truly odd thing about Kass’ stance is that nuclear transfer — the demon that scares him the most — is the least morally challenging technique for developing stem cells. Nuclear transfer does not involve the creation of new humans; it merely amplifies a patient’s own tissue. We’ve been creating skin cultures for burn patients for years using techniques that are very similar to stem-cell culturing. It takes tortured logic to ban this whole field of medicine simply because somebody might do something bad with it.
Kass makes an interesting and seemingly hypocritical delineation in this debate: He claims to have no problem if medical research uses embryos left over from fertility clinics. But researchers know that stem cells derived from a foreign blastocyst will provoke an immune reaction, as will any foreign DNA. And, unlike nuclear transfer, an actual fertilized blastocyst is killed in the process. If there were any slippery slope to consider, it would probably involve these newly minted humans — where parental genes have been mixed — not just some cells cloned from one patient.
While cloned cells are merely an amplification of a patient’s own tissue, a fertilized embryo is a potentially novel human. Kass seems to have it backward, wanting to ban experiments with a patient’s own tissue, but condoning experiments on fertilized embryos.
Kass warns that if any kind of cloning is allowed, there will be “trafficking in clones.” But who would these traffickers be — and why would they be trading in clones? Are we talking about an army of Saddams? Not likely, since cloning, no matter how sophisticated the cloners, would constitute a pretty inefficient method of conscripting an army. No, these evil “clone traffickers” would mostly be people with fertility problems, desperate to have a child.
It’s helpful to keep an image of these particular “criminals” in mind when listening to Kass’ arguments. He’s disturbed by the idea that human embryos would be created solely for research, but he keeps forgetting that we’re talking about a blastocyst, which can’t become a human fetus unless it’s implanted in a womb. Until that time, the stem cells are basically thin scum in a petri dish. They are your cells, they belong to no one else, they have only your DNA and no one else’s. They were never fertilized, and there is no intent to make an embryo.
Kass calls the ban on therapeutic cloning “the opening skirmish of a long battle against eugenics,” and that is where the core of his argument seems to lie. Kass knows his history. He’s aware of the horrors perpetrated by Nazi scientists and the tragedy of state-sponsored eugenics. And there is no doubt that we must remain ever vigilant about the behavior of scientists and the fruits of their research.
But the threat of eugenics shouldn’t provoke such a knee-jerk response. Was it wrong to wipe out smallpox? Most people think the question is insane — of course not! Yet we wiped out smallpox; we wiped out a gene that was a part of nature. That’s tantamount to global eugenics. The same thing could happen to the gene for Huntington’s. We could track it down and eliminate it from the gene pool. How could anyone be against that? Why in the world would the government be interested in preserving bad genes? But that is exactly on Kass’ sweet spot. He believes we start to lose our humanity when we take control of our own genetic destiny.
According to Kass, it is a deeply fundamental aspect of life to suffer and die. When we try to fix this natural order, we lose our soul, our essential humanity. This is a dressed-up version of the creaky “natural law” argument that John Stuart Mill shot down in the 1800s.
Kass’ theories are based on the idea that nature knows best. This is the antithesis of scientific progress, which is always trying to control nature. Those who abide exclusively by natural law are comfortable with diseases because they’re a part of nature. Science aims to tame nature and cure diseases. Reasonable people will accept parts of each philosophy, but Kass comes down too firmly on the side of nature, to the detriment of humans.
The American Heart Association has estimated that 128 million Americans have diseases that could be cured or ameliorated by embryonic stem-cell therapy. Kass knows this number. In pushing hard to ban therapeutic cloning, he is apparently willing to sacrifice this group. This is an incredible price to pay for one man’s vision of human purity.

Gov. Rick Perry underwent stem cell therapy
...the kind that Christian conservatives like
FILE - In this June 18, 2011 file photo, Texas Gov. Rick Perry speaks at the Republican Leadership Conference in New Orleans. Should Perry conclude that voter discontent has left him an opening to enter the presidential race, the longtime Texas governor would be among the GOP field's most conservative candidates. (AP Photo/Patrick Semansky, File)(Credit: AP) Rick Perry, the Texas governor who may soon enter the GOP presidential race, is an outspoken critic of stem cell research. Earlier this year he claimed that under the Obama administration, stem cell research was “turning the remains of unborn children into nothing more than raw material.”
It is perhaps surprising to learn, then, that Perry himself was injected with stem cells last month to treat a recurring back injury, as the Texas Tribune revealed. However, Perry was treated with adult stem cells from his own tissue, not embryonic stem cells.

Justice Department will appeal ruling in stem cell case
Federal judge has blocked additional taxpayer money from being used in embryonic research
The Obama administration will appeal a court ruling that undercut its efforts to expand stem cell research, the Justice Department said Tuesday.
The appeal is expected this week, said spokesman Matthew Miller.
On Monday, a federal judge ruled that the stem cell research violated the will of Congress in prohibiting the destruction of human embryos.
National Institutes of Health Director Francis Collins said dozens of studies of promising stem cell therapies — about $54 million worth — would have to stop because of the court ruling that temporarily forbids any additional money from being granted.
Monday’s ruling will “drive the best scientific minds into work less likely to yield treatments,” added Sean Tipton of the American Society for Reproductive Medicine. “It will be incredibly disruptive.”
Stem cells reverse blindness caused by burns
In a study deemed a "roaring success," dozens of people regain their vision after transplants
Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells — a stunning success for the burgeoning cell-therapy field, Italian researchers reported Wednesday.
The treatment worked completely in 82 of 107 eyes and partially in 14 others, with benefits lasting up to a decade so far. One man whose eyes were severely damaged more than 60 years ago now has near-normal vision.

I used to be a sports-hating snob. Then I fell for a fan and discovered football is the best reality TV there is
In 1977, the Oakland Raiders finally made it to the Super Bowl. I was living at the beach that year, temporary roommates with my best friend, Stephen Salinger, a life-long Raiders fan. He made food, invited friends in, cheered through the game and celebrated for days after the Raiders’ decisive 32-14 win against the Minnesota Vikings.
I went surfing.
He couldn’t believe it. I had to be the only man in America not watching the game. It was perverse, it was pathological. It was unpatriotic. But there was a swell running and, in a favorite phrase of mine at the time, football was just “guys jumping into piles” anyway. I thought I was “above” football, but the truth is I was a petty little snob from an Upper East Side, socialist-leaning family. (My mother voted for Adlai Stevenson. Twice.) We went to antiwar demonstrations and Pete Seeger concerts (yes, we sang along), not football games. Running photographs at half-time from Shea Stadium to the pressroom at the Daily News, years before, I had gotten a closer brush with the sport. I came away impressed by the sheer size of the players and the gladiatorial brutality of the game itself. But I wasn’t inspired to watch.

It's an interesting question, but let's keep in mind that not everyone's asking it
After my first reading of a Chicago Tribune article about parents deciding what to do with leftover embryos following IVF treatment, I was so confused I had to consult my smart friend Laura. I IM’ed her the link and asked, “Am I crazy, or does this article totally take it on faith (ha!) that everyone deciding what to do with an embryo is religious?” Laura’s verdict? “Man, those babies in the picture are cute. Especially the yawning one.” Also, “You are definitely not crazy. This is an article about Christians struggling with this decision, which is very interesting, but nowhere in the article does the writer specify that.”
