Depending on whom you ask, stem-cell research is either a medical godsend or further proof that God is dead.

IRV WEISSMAN'S HOME IS ABOUT 20 MINUTES FROM Stanford University, hidden from the road by a tall stand of trees. Inside, all of the rooms are spacious, but the living room is more so. The ceiling is high and broad-beamed; the furniture, Western chic: chairs hewn from tree branches, tables built from tree trunks. The couch is a curving affair that looks a little like a giant, gold earthworm caught in a pillow fight. Spread out in front of the fireplace is a bearskin rug. This bear has seen better days. Irv Weissman is talking about how those days came to an end.


"We ate him. Rare. We were a little nervous about it because most wild bears have trichinosis, but what the hell."


Irv Weissman doesn't look the bear-eating sort. He's of middle height, middle weight, mildly balding, with fine clothes, a jovial aspect and a long, wispy beard. He is a scientist, yet looks more like a Russian poet or an aged food critic. Beneath this exterior, however, he's just a boy from Montana - the grandson of a Jewish homesteader who, upon arriving at Ellis Island, walked across the country and tried his hand at mining, fur trapping and eventually opened a hide shop that became a group of hardware stores; the son of a man who, when wounded by a knife-wielding assailant, was tough enough to fight back and beat the man silly - so silly it made the papers. Which is to say Weissman comes from a culture of bear eaters.


So why is he living among Stanford academics and not in Great Falls, Montana, with other bear eaters? When Weissman was 10, he read Paul de Kruif's book Microbe Hunters, which describes the work of Ehrlich, Pasteur and other early bacteriologists. He quickly decided science was more interesting than hardware. By the time he was in high school, he worked at a lab in Great Falls doing transplantation research. He published two papers, on cancer and transplantation, before he was 18.


Weissman entered Dartmouth College but found that he didn't fit in with either the East Coast Jews or the East Coast non-Jews. After two years he transferred back to Montana State University in Bozeman, where he could study premed without worrying about how a Jew from Montana was supposed to behave on the East Coast. He left the state again in 1960, entered Stanford Medical School and one way or another has stayed for the duration. Currently, he's a professor of cancer biology and a professor of pathology. In 2002, he was voted California Scientist of the Year.


True to his roots, Weissman approaches science like a Montana boy - charting unexplored realms, pioneering in the lab. His early work focused on how the cells of the immune system fight cancer. He spent much of his time studying the relationship between blood cells, cancer and radiation. Because of the research that emerged after the explosion of the atomic bombs over Hiroshima and Nagasaki, scientists knew that exposing the human body to radiation wiped out both blood cells and cancer cells.


They also knew that after irradiating the body (chemotherapy), you could perform a bone-marrow transplant using marrow from a healthy, cancer-free donor and that something in that new bone marrow would begin producing all sorts of cells. "We knew there must exist a very rare cell inside the bone marrow that would give rise to all types of cells - but this was only a theory," says Weissman. "No one had ever isolated that cell. I started wondering how to tease it out from all the others."


This was in the late '60s. For years, Weissman worked in his lab sorting cells. An easy way to think about this is that he took mouse blood and poured it through a long series of strainers. With each pass a different kind of cell was removed. Out came the T cells, out came the B cells, the red blood cells, the white blood cells and on and on until there was only one kind of cell left. Finally, in 1988, Weissman managed to do something that no one else had ever done, something that most people didn't even think was possible: He isolated a cell that gave rise to all other kinds of blood cells, a blood-forming stem cell. He also became one of the first people on the planet to realize the promise of what he had done. This has made him a controversial man.


If you've been living inside a Himalayan cave, perhaps you haven't heard about stem cells, but otherwise the gist has been hard to miss. Scientists from all fields have been harping on stem-cell research as the most important directed medical-research effort ever. When Irv Weissman started working with mouse cells, he realized, nearly from the beginning, that he was onto something that could potentially save millions of lives. "I knew that if I could ever do this in humans," he says, "I would be able to use chemotherapy to wipe out cancer cells and then transplant in new stem cells that would be completely disease free."


Cancer wasn't the only thing on his mind. Weissman knew that a great number of the body's terrible diseases - Alzheimer's, diabetes, Parkinson's, others - are caused by misbehaving cells and that it might be possible to remove the bad cells and replace them with normally functioning stem cells. In America, 1.3 million people have cancer; 4 million have Alzheimer's; 1.5 million have Parkinson's; 17 million have diabetes. This doesn't include those in need of a new kidney or bladder or spinal cord - which stem cells could possibly be used to grow. That's a lot of lives to save.


What Irv Weissman didn't understand at first is that his own government could politicize these stem cells and decide that potentially saving millions of lives was a bad idea. What he didn't understand then, but has come to understand since, is that without his rugged Montana perseverance, he might not ever get the chance to save these millions of lives.



R. ALTA CHARO, A PROFESSOR OF LAW AND MEDICAL ethics at the University of Wisconsin, Madison, who served on Bill Clinton's bioethical council and who has been a part of this discussion since nearly the beginning, likes to say, "The stem-cell debate is a debate about everything but what it's about." Which is to say that the stem-cell debate is not, actually, about stem cells.


Really, it is about George Bush trying to win a second-term election after not actually winning the first. It's about the son not making the same mistakes as the father and losing the religious right. And it's about the religious right trying like hell to pave the way for the Supreme Court to take away a woman's right to have an abortion.


A discussion of this requires a little more background on the five ways scientists obtain stem cells. The principal method is through a process called somatic cell nuclear transfer, which we'll get to in detail soon. But for now we'll concentrate on the other four. One of those ways is through parthenogenesis, the Greek word for virgin birth. In this process, an unfertilized egg is tricked into cell д division and then mined for stem cells. Another way is to take one of the existing 60 cell lines and form another cell type to create new lines. Both of these ideas are exciting, but no one really knows if or how well either will work, and so, for now, both are off the radar.


In the remaining two methods, fetal stem cells are culled from aborted fetuses and embryonic stem cells are removed from unused embryos taken from in-vitro fertilization clinics. Because of these methods, stem cells sit smack in the middle of America's reproductive-rights debate. In fact, some have argued, the debate over the process of culling stem cells is the best thing to happen to the religious right's anti-abortion crusade in decades.


"Every year since Roe v. Wade (news - web sites) thousands of women have been having abortions," explains Charo. "That's 30 years, an entire generation of women who have experienced the ability to choose. That's a huge demographic imperative. The evangelical right is fighting against a culture of tolerance for embryonic destruction, and they're losing that fight every time a woman knows she can make a choice. The conflation of cloning and stem-cell research has allowed [the religious right] to argue for the embryo in the context of a technology - reproductive cloning - that has a near-universal shock value."

It's a tricky thing to try and overturn a Supreme Court decision like Roe v. Wade. Nonetheless, for 30 years, foes have been chipping away at it. One of the main reasons it has held fast hinges on this idea: A human embryo does not have the same rights as a human being. To overturn the decision you need at least a couple of things. One is a pro-life Supreme Court (which is a whole other can of worms, but it starts with what we just got - a pro-life Senate). The other is evidence that supports the idea that the American public now feels that embryos are people too.

For the benefit of reporters and congressmen locked in this debate, Irv Weissman does an interesting experiment. He walks up to strangers on the street and asks them to draw an embryo. "Invariably," he says, "every time, without fail, they draw a fetus with a face." A fetus with a face is not an embryo. An embryo is a scientific term used to describe the period of time from when a zygote is formed until the time it begins to have discernible organs. Meaning, specifically, that the word embryo was created to distinguish it from a fetus. It is nothing like the cartoons that people draw. In fact, under a microscope, an embryo is even less spectacular than stem cells.

If you want to prove to the Supreme Court that both the scientific community and the American public have changed their minds about the status of the embryo, then you need a series of precedents. These are not just legal precedents; these are psychological precedents as well. The high court would need to decide that the country's opinion has changed, and to do this you would need to show that in related - but not abortion-specific - departments the embryo is now being afforded the same protections as both fetus and adult.

To this end, Bush has stacked a bevy of anti-choice judges in the lower courts and appointed an anti-choice attorney general in John Ashcroft (news - web sites). And while you could argue that this is just party politics - and it is - behind the obvious partisan court appointments there are covert anti-choice precedents being set.

Last October, the Bush administration changed the section of the Health and Human Services (news - web sites) charter that regulates research done on human subjects. This legislation exists so that if you volunteer for a sleep study, you don't end up dead. The old charter granted legal protection to adults and fetuses. The new version protects embryos as well.

For a long time, women's groups have been lobbying the government to provide health care for pregnant women. To this end, the Bush administration extended the reach of the State Children's Health Insurance Program to cover both embryos and fetuses but, oddly, not pregnant women. So, while pregnant women still can be without health care, the groups of cells dividing in their uteruses now have more health coverage than their uninsured mothers.

Bush has also lobbied hard for a ban on partial-birth abortions, which technically eliminates the already rare late-term abortions but in effect criminalizes the procedure. Bush also reinstated Ronald Reagan (news - web sites)'s gag rule that bars federally funded family planners from discussing abortion as an option or from providing abortion services.

"The point of these things," says Allison Herwitt, director of government relations for the National Abortion and Reproductive Rights Action League (news - web sites) "is to weave embryonic rights into law. These are not individual occurrences. These are a well-crafted strategy to end legal abortions. And one of the next steps in that strategy is to outlaw stem-cell research - not because the research itself is in question, but because banning the way that research is conducted can help them to achieve their true goal."


UNDER A MICROSCOPE, STEM CELLS aren't much to look at. They grow in clusters and even when magnified 10 times are individually smaller than pinheads. They look like slimy, slightly metallic grapes. Under a microscope, it would be easy to mistake them for something utterly inconsequential, like tadpole snot.

"It's almost funny," says Larry Goldstein, "that something so dull-looking could cause such a fuss."

Goldstein, another scientist in the middle of this stem-cell storm, is a plain-spoken, energetic man in his late 40s. He has gray hair and a long, handsome face. As an investigator and professor of cellular/molecular medicine at the University of California, San Diego, he oversees a lab that employs 23 people and thousands of mice. Both mice and men are working toward answers to the same set of questions: how biological complexes (proteins, lipids and organelles) move through the neurons and brain cells.

He wants to know these things because he thinks the answers will go a long way toward providing a cure for Alzheimer's, Huntington's chorea and Lou Gehrig's disease (news - web sites). To get the answers, he needs stem cells.

Stem cells are the body's rawest materials. From them, developing embryos build all other cells that eventually form the body. Unlike specialized cells that can only form one thing - a liver, say, or a nose - stem cells can change into any other kind of cell.

Currently, much of Goldstein's work involves non-human-derived stem cells, which are not technically a point of contention. "But five years from now, if I want to actually cure these diseases, I'll need access to human embryonic stem cells, and I want to make sure they're available."

The issue of stem-cell availability is at the root of a war of terminology. Both sides are using big words, and some of those words have frightening connotations. Ignorance is part of the problem. Because of the complexity involved, the media often choose brevity over accuracy, and the combatants fuel the war by co-opting partially defined words to their own ends.

Cloning is one of the biggest bombs in this terminology war. "You have to understand something," Weissman says. "Cloning has as many meanings to a scientist as ice to an Eskimo or love to Oprah Winfrey." On the other hand, cloning, to a man like Leon Kass, means only one thing: producing carbon-copy human beings.

Leon Kass is yet another controversial man at the center of this battle. He is a University of Chicago bioethicist who believes that life begins at conception and who now heads up President Bush (news - web sites)'s Council on Bioethics. Time magazine called him the president's "ethics cop." The council is charged with advising Congress and the administration on stem cells. A few years ago Kass wrote a now-famous article for The New Republic titled "Preventing a Brave New World or Why We Should Ban Human Cloning Now." He explained the aforementioned procedure called somatic cell nuclear transfer (SCNT), the principal means of obtaining stem cells, and disingenuously equated that process with the cloning of people. Here are a few lines taken from Kass' article:


What is cloning? Cloning, or asexual reproduction, is the production of individuals who are genetically identical to an already existing individual. The procedure's name is fancy - "somatic cell nuclear transfer" - but its concept is simple. Take a mature but unfertilized egg; remove or deactivate its nucleus; introduce a nucleus obtained from a specialized (somatic) cell of an adult organism. Once the egg begins to divide, transfer the little embryo to a woman's uterus to initiate a pregnancy. Since almost all the hereditary material of a cell is contained within its nucleus, the re-nucleated egg and the individual into which it develops are genetically identical to the organism that was the source of the transferred nucleus.


Scientifically, Kass is correct, except - and this is a big except - SCNT stops short of transplanting that egg into a woman's uterus. What Kass knows, but chooses not to acknowledge here, is that once that new egg begins to divide, one of two things can happen. The first is it could be implanted into a woman's uterus and develop those dreaded carbon copies. This process is called "reproductive cloning," and almost every mainstream scientist the world over, including Weissman and Goldstein, opposes it.

The second thing that could happen is what opponents of this work like to call "therapeutic cloning." Weissman prefers "nuclear transplantation to produce stem cells." Either way, in this second scenario, once that very early embryo (a cluster of 100 or so cells called a blastocyst) is formed, there is a two-week window during which the stem cells are extracted. In doing this, the embryo becomes unsuitable for manufacturing the dreaded clones, or any other viable human form for that matter. If you wanted to create another human being, you would have about as much luck successfully implanting that enucleated embryo into a woman's uterus as you would have growing a Buick by planting an engine block in the ground.

Kass' apparent attempt to equate SCNT with the "production" of cloned individuals becomes egregious because his knowledge and opinions are being used to enact legislation that will then affect the entire country.

A clear indication of Kass' sway took place in the spring of 2001, when a pair of cloning bills was introduced, one in the House and one in the Senate. The original House bill went nowhere, but it was quickly rewritten and reintroduced by Dave Weldon (R-Florida). On July 31, 2001, after three hours of debate during which conservatives spoke about eugenics, commodifying humanity, the peril of private-industry control over the human genome (news - web sites), the need for science to operate within social and ethical norms, and - of course - the Nazis, the House of Representatives passed the Weldon Bill 265 to 162.

The bill (and its sister Senate bill, which was introduced by Kansas Republican Sam Brownback and is known as the Brownback Bill) seeks to outlaw all forms of cloning - both reproductive and therapeutic - with severe penalties of up to a $1 million and 10 years in prison for either doing research or receiving medical treatment based on that research. This means that if the French invent a stem-cell-based cure for Alzheimer's and you go to France and receive treatment and try to re-enter the United States, you're not passing go, you're going straight to jail. The only good news is that since your Alzheimer's is now cured, you'll remember the whole experience.

On August 9, 2001, President Bush, in his first address to the nation, echoed Kass' fear-mongering and followed his lead: "We have arrived at that brave new world that seemed so distant in 1932, when Aldous Huxley wrote about human beings created in test tubes in what he called a hatchery."

Bush then issued an executive order restricting federal research money to the 60 previously harvested stem-cell lines. These lines were cultivated between 1998, when human embryonic stem cells were first isolated, and the moment Bush put the kibosh on further work. Never mind that the majority of these lines have not been studied enough to know if they're actually safe for use in humans.

"But the real problem with them," says Weissman, "is that all 60 lines come from people who utilize in-vitro fertilization clinics. Part of the problem is IVF clinics serve a very specific segment of the American population. The stem-cell lines taken from IVF clinics are cell lines taken from rich, white, infertile people. We have no idea if stem cells possess ethnic, genetic variation - and they might. One of the fundamental principles of bioethics is called distributed justice. That means when scientists work on medical cures, they want to develop cures for everyone - not just for rich, white, infertile people."

In other words, scientists want to study a rainbow coalition of stems cells, but by limiting research to existing lines, compassionately conservative George Bush has created a stem-cell policy much like his tax cut: The rich get richer, the poor get screwed.


SPEND FIVE MINUTES WITH JERRY ZUCKER and you'll think that his life could have gone either way. One wrong turn and he would have ended up still working the coat check and living with his mother at 50. He wears cardigans. In conversation, his voice is several decibels below soft-spoken. Words hang up on his lips. He has soft features, bushy eyebrows, errant hair and, all told, looks like someone in constant, mild pain. The one thing he doesn't look like, and this may be his great genius, is Hollywood royalty, or at least its court jester.

Zucker created his own brand of movies, a genre of wack-job comedy that began with Kentucky Fried Movie, was perfected in Airplane! and which includes the Naked Gun and Police Squad franchises. He also made a sweet movie about a dead guy, a live woman and a pottery fetish called Ghost.

Zucker Productions is a few modest rooms located in a peach-walled building in Santa Monica. Zucker's movies are such flamboyant affairs, it's hard to imagine them beginning in rooms this small.

It's also hard to imagine Zucker as the political type. Though he attended the University of Wisconsin from 1968 to 1972, when Madison was a radical hotbed (the legendary Vietnam protest documentary The War at Home was filmed then and there), Zucker was, by his own admission, "never much more than a weekend rioter." His politics are still middle-of-the-road.

Since then, not much has changed. Yet everything has changed. In 2000, Zucker found out that his 11-year-old daughter, Katie, had juvenile diabetes. Immediately, he began researching the disease and hunting for hope. In the summer of 2001, he started hearing about something called stem cells and how they might be able to not just provide better treatment, but actually cure the disease. That summer he also heard that the Weldon Bill had passed, that President Bush was limiting research to 60 mostly moribund cell lines and that the Brownback Bill was heading for a vote in the Senate where only seven members were in favor of keeping the research legal.

"As a director," says Zucker, "I tend to be calm. I don't want to be another Hollywood maniac. I try not to get carried away or lose my cool. What was going on with stem cells made me very angry."

Through sad coincidence, Zucker and his wife, Janet, had gotten to know Douglas Wick (the producer of Gladiator, Stuart Little and Working Girl), and his wife, Lucy Fisher, the former vice chairman of Columbia TriStar Motion Picture Group. Wick and Fisher also have a daughter with juvenile diabetes. The foursome had been active in the Juvenile Diabetes Research Foundation, but wanted to be at the forefront of the stem-cell debate and felt that if they started their own organization they could not only act quickly, they could bring the full weight of Hollywood to bear on the situation.

Together they hired a lobbyist and went to Washington. They took their daughters and Caltech stem-cell biologist David Anderson along. They called this new group CuresNow. This was in the summer of 2002. To give you an idea of how strong the love affair between D.C. and Hollywood is, what did CuresNow do to get in to see senators?

"Um," says Zucker, "I just called up and said this is Jerry Zucker."

They looked at their trip as an educational crusade. They punched below the waist. "We would walk in to a senator's office with my daughter and her insulin pump attached to her belt and ask them what was more important - my daughter's life or the life of a couple of cells?"

In a sense, CuresNow was fighting against the work of its founders' business. In the minds of many, stem cells are directly linked to cloning, and the public perception of cloning is directly linked to Hollywood. "We spent the better portion of the 20th century making mad-scientist movies," says Zucker. "One of the first senators we met - I can't tell you his name - went on and on about how if we let this technology go forward someone will try to create a new Hitler. How much of that is real fear and how much of that is Hollywood?"

As they suspected, most of the politicians didn't really know what they were voting on. The Hollywood crew explained things slowly, and slowly began making headway. One of their early converts, who remains their strongest ally on the right, was Utah Republican and pro-life advocate Orrin Hatch. Centenarian Strom Thurmond joined their cause. Senate Minority Leader Tom Daschle agreed not to put the Brownback bill on the floor for a vote until CuresNow had a chance to talk to everyone who would listen.

Hatch, alongside several other senators (Feinstein, Kennedy and Specter), introduced his own bill that banned reproductive cloning but allowed therapeutic cloning. Neither his bill nor Brownback's could gather the votes needed to pass. Instead, Brownback tried attaching anti-cloning to several other bills, but CuresNow was making headway. The word was getting out, and none of the anti-cloning amendments have met with success. Currently, 60 senators favor stem-cell research, and the Senate vote is still pending.

Since the recent Republican gains in Congress, CuresNow knows that its Washington work is not done. But Zucker and company are spending an equal amount of energy in California because it's here that lines are being drawn and the first major battle for stem-cell research is being fought.

"California is the country's biotech leader," says Zucker. "We have brilliant scientists and a receptive state government. I want to see California as a safe haven for stem-cell research. We have a history of leading the nation in fights such as this. We have a great chance to add to that history."


THE 10th AMENDMENT TO THE U.S. Constitution reads: "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." Politically, this is the typically Republican turf known as states' rights. It exists as a barrier to top-down, Washington-mandated policy. It is the legal reason California was able to legislate lower emission standards than the national standards mandated by the Clean Air Act. The rest of the nation followed California's anti-emission movement; car manufacturers, to their dismay, had to comply. California Democrats had used one of the Republicans' favorite weapons - states' rights - to spark a state-by-state subversion of the GOP's big-auto agenda.

This tactic doesn't always work. In 1996, California passed Proposition 215, making marijuana available with a note from your doctor, like any other prescription drug. In the ensuing years, nine other states legalized medical marijuana. George W. Bush promised in a 2000 campaign speech to leave medical marijuana as a states'-rights issue, saying, inimitably, "I believe each state can choose that decision as they so choose."

But in May of 2001, the U.S. Supreme Court (news - web sites) in U.S. v. Oakland Cannabis Buyers Cooperative ruled against the 10th Amendment, and in 2001 the Drug Enforcement Agency started raiding California's buyers clubs and growers organizations, confiscating wares and imprisoning owners.

It doesn't take an astute political analyst to realize that two of the engines driving the Republican Party are economics and morality. There are many different ways of looking at the conflicting tales of emissions and medical marijuana. The least cynical is to believe that the country was ready for cleaner air and not ready for legalized drug use. A more jaundiced view says that pollution laws had two things going for them - they didn't contradict federal law and, since Californians buy more cars than anyone else, compliance carried an enormous economic incentive. Medical marijuana, on the other hand, goes against federal law and also lacks an economic impetus since you can't tax its sale. Most important, it offends the moral standards of the right.

The California biotech industry is a huge economic impetus. In 2001, when President Bush limited stem-cell research to the 60 previously existing stem-cell lines, he effectively yanked a huge segment of biotech research to a dead halt. Moneys were drying up, and America's top scientists began leaving the country and moving to places with fewer restrictions - an effect that analysts quickly dubbed the "brain drain."

Almost immediately following Bush's August announcement, University of California at San Francisco stem-cell pioneer Roger Pedersen packed his bags and lab and moved to England, where stem-cell research is permitted. Other countries, including Israel, Japan, France and Australia, have made themselves friendly to the work. Last year, Singapore took an even more aggressive stance, declaring itself a center for stem-cell study, breaking ground on a $15 billion research park and quickly poaching top U.S. minds including Edison Liu, once a leading researcher at America's National Cancer Institute (news - web sites) and now the head of Singapore's new Genome Institute. There's even talk of an international consortium for stem-cell research similar to the one that cracked the human genome.

To combat the brain drain and bring more biotech money into California, state Senator Deborah Ortiz (D-Sacramento) introduced Senate Bill 253. The bill allocates the use of state funds and private donations for stem-cell research within California.

If your idea of a senator includes gray hair, a stentorian voice, pinstripes and steely eyes, then Senator Ortiz does not fit the bill. She looks like a suburban housewife and acts like an endearing grandmother. On the day we met, she arrived carrying Greek pastries that looked like failed geometry experiments oozing filling. She is an easy woman to underestimate. One gets the feeling that she spends her days nudging legislation into law.

In her day, she has nudged quite a bit of legislation into law. In 1993, she was elected to Sacramento's City Council and fought a nasty fight for safer neighborhoods and tougher gun control. In 1996, she was elected to the state Assembly. That same year her mother was diagnosed with ovarian cancer. In the Assembly, Ortiz gave state workers a long-overdue pay raise and created a statewide after-school learning program for at-risk students. At home she became an armchair cancer specialist. "I read all the studies and I read the footnotes." But there was no cure in the footnotes, and her mother died in 1999 during Ortiz's first state Senate term. Knowledge led her toward advocacy. Ortiz earmarked $25 million for ovarian-cancer research, but felt that wasn't enough.

"From the footnotes I came to believe that the cure for cancer has to exist at the cellular level," Ortiz says. "Stem-cell research is the next wave." When she was re-elected to the state Senate in 2002, she turned her attention to stem cells. It wasn't just a cure for cancer that drove her decision. She knew that California took a $12 billion hit in the dot-com crash, and recent studies claim that the state's budget deficit will exceed $35 billion in the next year and a half. On September 22, 2002, Gray Davis signed SB 253. Ortiz had nudged perhaps her biggest bill into law. California became the first state to legalize stem-cell research.

"By signing SB 253, we have opened the door to important life-saving research in California," said Davis, when asked about the bill. "There are strict parameters to stem-cell research built into the bill, but the possibility of some of the industry's top science researchers finding a cure to fatal diseases such as Alzheimer's and Parkinson's diseases, spinal-cord injury, stroke, burns, heart diseases, diabetes and arthritis is priceless. We fully expect stem-cell research to attract world-renowned scientists to our state. Currently, there are 2,500 biomedical companies in California that employ 225,000 people. During 2000, this industry paid its employees $12.8 billion. While this life-saving research will continue to bring the necessary [private] funding into the state, it will more importantly save lives."

Almost immediately after Davis signed, other states followed California's lead. New Jersey, Pennsylvania, Louisiana and Rhode Island have already legalized therapeutic cloning, and Massachusetts and New Mexico are considering similar proposals.

This grassroots, states'-rights movement on stem-cell research presents a dilemma for Republicans. The old-school, economic Republicans are interested in free enterprise and biotechnology - the economic imperative. The new-school, moral Republicans are interested in homogeneous morality and banning abortion. Stem cells split the two sides of the party. One of the reasons for the terminology war is that the Bush administration needs to create a cloning bogeyman in order to bridge the schism in his party. This way he appeases the moralists while doing an end run around the economists who would be rather pleased with biotech billions.

It is interesting to note that there is no Bush administration or religious-right opposition to the in-vitro fertilization process, despite the fact that in the normal course of in vitro, multitudes of embryos are destroyed. During in vitro, ova that have been extracted from a woman's body are fertilized in a petri dish. On average, 20 or so embryos are created, but only one is implanted. The rest are temporarily frozen and then eventually discarded. This means that while the administration and the religious right are opposed to using those ill-fated embryos for stem-cell research, they are more than happy to turn a blind eye to their destruction in the name of pregnancy. This is because their anti-abortion legal strategies call for defining life ever earlier and ever more clinically - as early and clinically as a dish in a refrigerator (talk about weird science). Also, they do not wish to confront sterile parents or hamper a multimillion-dollar industry.

So sure, it's a tad dramatic to say that what followed SB 253 is a high-stakes poker game with states' rights, Bush's second term, abortion legality, the biotech industry and medical science as major players. In less dramatic language, what's happened in California is that the two key issues driving the Republican bus have come into head-on conflict with each other, and it's because Democrats have forced the issue by playing the states'-rights card.


JUST BEFORE DAVIS SIGNED ORTIZ'S bill into law, Andy Grove, the chairman of Intel, donated $5 million to UCSF for a stem-cell biology program. Because of Bush's restrictions, anyone wanting to do stem-cell research requires facilities that are completely unattached to anything receiving National Institutes of Health (news - web sites) dollars - thus separate buildings, labs, equipment and such must be constructed. The $5 million won't pay for much of that, but it was the first major private donation and a good start.

In Irv Weissman's home, on the evening of December 11, a small dinner party was held to celebrate the next step - that being Stanford's announcement a day earlier that it plans to capitalize on $12 million of anonymously donated seed money and build a $120 million Institute for Cancer/Stem Cell Biology and Medicine headed up by Weissman. Building on his previous research with blood-forming stem cells, the Stanford institute will initially turn its attention to discovering the stem cells that become the other major organs of the body - that way, if these organs become cancerous, they'll have new ways to fight the disease.

Weissman does not look like a man in celebration. His movements are careful, his brow creased. He wears a chef's apron and stands at the stove, studying the goose he's been busy cooking.

Around the dinner table sits a hungry crew. Weissman's sister Lauren, once a Hollywood producer with five major films to her credit and now the executive director of CuresNow, is there. As is Lee Hood, another top scientist and the man who invented the DNA sorter that facilitated the sequencing of the human genome; and Ann Tsukamoto, a scientist with StemCells Inc.

Weissman maintains a robust wine cellar, and there are a number of prestigious bottles sitting unopened on the counter and a number sitting opened on the table. In between gobs of goose and glasses of grape, Weissman explains the focus of Stanford's new research institute.

"It's not only new ways to fight the disease," he says. "That's only the first step. We also know that there are cancer-forming stem cells. If we can isolate these, we can get to the very root of every type of cancer. This would give us new, biologically specific targets for drugs. And because the institute is in this state, California will be the first place these therapies will come out. Our biotech companies will produce them, and Californians will get the first crack at these treatments."

Even this is only the tip of the iceberg. The institute plans to improve the efficiency of SCNT, and once that's done they can begin growing diseases from scratch - which means they'll develop a fundamental understanding of how the body gets sick. So, when the Bush administration says it opposes all forms of cloning, it is, in effect, saying it opposes the best bet yet for curing cancer.

As expected, Stanford's announcement sparked a firestorm. All of the top papers and top news shows reported the story, but not one bothered to explain the tie-in between the stem cells and cancer. Instead the words human cloning got heavy play. The Associated Press was the first to cover the story, and its article began: "Stanford has said its new cancer institute will conduct stem-cell research using nuclear-transfer techniques - work that many consider to be cloning of human cells." ABC News followed suit: "The president believes that the creation and destruction of embryos for the purpose of research or reproduction is morally wrong. He is against cloning of any kind and feels there are other biomedical-research avenues."

Leon Kass immediately issued a press release claiming that "Stanford has decided to proceed with cloning research without public scrutiny and deliberation," and went on to say that the president's bioethics council does not endorse the Stanford institute, and then noted the council wanted a four-year moratorium on so-called therapeutic cloning. Oddly, the council never recommended a moratorium (which Brownback has recently been calling for and which stem-cell researchers across the board consider a terrible idea), and Kass issued his statement without bothering to consult the rest of the council.

Not that any of this behavior is all that surprising. This is just a little lying in the face of a bigger war - a war that is far from over. The cloning debate rages on at all levels of government, refueled by the recent Raelian announcement that they had created the world's first human clone. Never mind that, just prior to that announcement, the Bush administration blocked a worldwide U.N. ban on reproductive cloning that might have stopped the Raelians in their supposed work. The ban was vetoed because it did not also include therapeutic cloning and was insufficient for the religious right.

So the opposition continues twisting terminology. Scientists like Larry Goldstein and the folks sitting around Weissman's dinner table are painted as cold-blooded and immoral. The government is actively clouding the issues, and the media has done little to engender understanding. Meanwhile, a middle-of-the-road estimate of how many Americans will die from diseases that stem-cell research might soon cure is 130 million.

Back at the stove, Weissman pokes and prods and eventually nods his head sagaciously: "That goose is cooked."

Conception Misconception
by Margaret Wertheim

WHEN DOES A HUMAN EMBRYO BECOME A HUMAN BEING? For right-to-lifers the answer is unequivocal: at the moment of conception. And this idea, that a person comes into being as soon as an egg and a sperm fuse, is the platform on which Christian conservatives are building their case against stem-cell research, especially the practice of therapeutic cloning, which they consider worse even than murder. In their eyes, a person is being created only to be destroyed.

Yet therapeutic cloning is the process on which many medical researchers are pinning their hopes for a new generation of cures. This technique would enable them to generate stem cells specific to each individual, thereby achieving a perfect tissue match. The problem is that in order to get these matched stem cells, you have to create an embryo. It's the same process used to create the infamous Dolly, but in therapeutic cloning there is no intention of letting the fertilized egg develop into a mature form. Embryonic stem cells have to be culled about seven days after fertilization - wait any longer and they begin to lose their all-important plasticity. At the seven-day mark, an embryo is a ball of just a few hundred cells known as a blastocyst; it has no viability outside a womb, and there is no differentiation of any tissue types - no skin or bone or muscle cells. Yet right-to-lifers would accord this ball full human status. The problem is, in the process of culling stem cells, the embryo is torn apart.

The sanctity of the human person is a principle on which almost everyone agrees, but just when this entity emerges is not easy to determine. Contrary to what many abortion opponents imply, there is no historical standing to the idea that a person begins at conception - not even in the Catholic Church. Nowhere is it written in the Scriptures that life begins in the blastocyst. Traditionally the formation of a child was understood to be a gradual process in which coming into being was associated with something called the "quickening." (Today the term is still used to mean the time that a mother first feels her fetus move.) In the fourth century, no less a Catholic authority than Augustine sanctioned abortion up to 80 days after conception. Not until 1588 did Pope Sixtus forbid all abortions, and that edict was rescinded three years later by Pope Gregory XIV. The first U.S. anti-abortion laws also distinguished an early period in fetal development: In 1821, Connecticut outlawed abortion after quickening, making early-term abortion perfectly legal. By the 1860s, however, all states had passed comprehensive criminal abortion laws.

Defining conception as the moment at which a person is formed makes abortion under any circumstances an act of murder, which is clearly the status Christian fundamentalists would like it to have. Under this calculus, any medical technique that destroys an embryo would also constitute homicide - no abortion, no therapeutic cloning, no embryonic stem-cell research (except in cases where the cells were culled from naturally miscarried fetuses). Yet, if we carry this logic through, we also have to ban in vitro fertilization.

IVF has enabled millions of infertile couples to share in the joys of parenthood, but locked away in the freezers of in vitro clinics are tens of millions of "surplus" embryos, the bulk of which will never be implanted. Parents of these embryos currently have three options: destroy them, donate them for research or continue to store them cryogenically. If personhood begins at conception, then the first two options will be ruled out as murderous, leaving only the third. Yet that too would constitute homicide, for cryogenic storage itself eventually kills the delicate embryonic cells.

The more science discovers about cellular mechanics, the more absurd it becomes to define a person at this level. If a single-celled fertilized egg, which is incapable of surviving on its own, is to be defined as a fully resonant human, then why not extend that status to an unfertilized egg, which is theoretically capable of parthenogenetic reproduction - i.e, without a sperm. (This actually happens in many species of fish and among some species of lizards and birds.) Cloned embryos themselves (including the therapeutic variety) are generated from ordinary body cells such as skin and muscle cells - in Dolly's case, the progenitor cell came from an udder. In this process the DNA-rich nucleus of the ordinary cell is scooped out and transferred into an egg whose own nucleus has previously been removed. (Alternately, the entire cell is simply injected into the denucleated egg.) If this new hybrid egg/cell is to be accorded human status, then why not the original cell itself? Which means that in effect every cell in your body is a full human being. Then, of course, there are sperm, each of which are just itching to fertilize an egg. The logical conclusion of this line of reasoning is onanism - to quote Monty Python: "Every sperm is sacred, every sperm is great, if a sperm is wasted, God gets quite irate."

As a former Catholic myself, I feel deeply ambivalent about abortion. Although as a feminist I believe every woman should be able to terminate an unwanted pregnancy, our goal should be to end the need for abortion. Sex education and contraception are the appropriate "technologies." My intention is not to dismiss what I believe are very real concerns here but to highlight the absurdities entailed in basing medical policy on a cellular definition of human life. Moreover, if we make personhood synonymous with a single cell, then how do we define death? Presumably that must come only when every cell in a body has died, and each one of those cells presumably also has the "right" to be kept alive as long as possible. Given the rapidly advancing technology of life support, such a policy carried through with any degree of social equity would quickly bankrupt our entire medical system.

Quark Soup: The Unbearable Likeness of Being
Twins, clones and multiple lives
by Margaret Wertheim
WHEN YOU WAKE UP IN THE MORNING, HOW DO YOU know who you are? The question has derailed philosophers, neuroscientists and artificial-intelligence researchers alike, but for kids on the playground, my sister Christine and I gave concrete urgency to the dilemma. As identical twins, how did we know who we were?

The myth of twindom is rooted in the idea of another being with whom one might be utterly at one, and I guess that's what they saw in us -- two tiny bob-haired girls with the same face and matching frocks bound together in a symbiosis apparently of another world. To most people we were so alike they assessed us as a single unit. But looking the same, sounding the same and dressing the same do not add up to being the same. Subtle differences in body shape and chemistry, slight deviations in personality, compound over the course of two lives to irrevocable difference. To borrow an insight from complexity theory, the human self is a system with "sensitive dependence on initial conditions," and even slight variations at the start inevitably lead to major changes later on. Though conceived in a single egg, two psyches ultimately evolve from one genome.

The gradual distancing of entwined souls is an experience known to all lovers and many siblings, but for identical twins the dawning of this gap strikes at the very core of identity. There is a moment in the life of every twin when you realize that this "other you" -- this clone -- is an alien, not you at all, but a doppelganger with a mind of its own. Flesh of your flesh, beyond your control, a twin haunts the world, an unbidden and alarmingly autonomous pseudo-copy. What is it doing? Where is it going? How is it outside your gaze? The challenge for twins is to let go, to accept this other being as a separate person entitled to its own unique life.

For many twins, however, the trauma of separation proves insurmountable, and they opt instead for the monoculture of a single life, the carbon-copy existence so beloved by evolutionary psychologists. This "Identi-Kit" vision of twindom is on display each August at the annual Twin Festival when thousands of duplicates in obsessively mirrored outfits converge in Twinsburg, Ohio, each pair striving for the most perfect match, as if they are all engaged in a psychotic game of Snap.

Surely there is something pathological about such determined togetherness. Unable to let go of their shared consciousness, Identi-Kit twins devolve into a kind of a microscopic Borg collective, trapping each other in a private cocoon that neither allows anyone in nor anyone out. Psychic meltdown can ensue. Such was the fate of the Gibbons twins, two young women in England who descended into a hermetic hell of pyromania and ended up in Broadmoor, an asylum for the criminally insane. No one has captured the seductively treacherous vortex of Identi-Kit twindom better than David Cronenberg in his cinematic masterpiece Dead Ringers, a chilling portrayal of what can all too easily become the unbearable likeness of being. Increasingly isolated in a spiral of erotically charged self-obsession, Cronenberg's two brothers finally have no way out but joint suicide. Whether cute or deranged (the Olsen twins being proof that the two are not incompatible), identical twins constitute an aberration of the natural order. In many tribal societies they are killed at birth.

THE RECENT CLAIM BY THE UFO-RELIGIOUS CULT the Raelians to have cloned a woman brings to the fore the hitherto hidden pathology of identical twins, for genetically speaking this Raelian clone would have the same relation to its "mother" as a pair of monozygotes to one another. Given the technical hurdles other cloning researchers have faced, few scientists believe the followers of Rael have actually cloned a human. At the same time, few doubt that sooner or later some scientist somewhere will succeed. If sheep and cows and pigs can be duplicated through nucleic transfer, there is no reason to suppose that Homo sapiens cannot also be replicated this way.

Raelians believe that all life on Earth was created by an advanced alien race whose grasp of genetic engineering it is our responsibility to emulate. The ultimate goal of human advancement as they see it is to learn how to duplicate our adult forms so that we can download our minds into a continuing sequence of new bodies and thereby achieve immortality. For Raelians, cloning is a necessary step toward fulfillment of our spiritual destiny. Chief Raelian researcher Dr. Brigitte Boisselier claims the group has more than 1,000 people currently waiting to clone themselves. Raelian scientists are supposedly working on the next generation, which Boisselier says will include clones of people with HIV (news - web sites) and AIDS (news - web sites). HIV patients risk passing the virus on to their offspring, and cloning offers a path to disease-free progeny.

Inability to conceive a child for any reason is surely one of life's cruelest tragedies, but, speaking as an unintended multiple, my skin crawls at the thought of deliberate duplication of a pre-existing person. Genetic duality is a difficult enough perversion to cope with even when you are going through it together, but at least twins grow up as equals. A child cloned from an adult would be anything but equal, condemned to live continually in the black hole of someone else's dreams and desires. Most repulsively, a clone would be forced to live in the shadow of someone else's body.

In The Importance of Being Ernest, Oscar Wilde observes that it is every woman's tragedy to become like her mother. And who of us does not flinch when we catch ourselves mirroring our mother? Even when we love our mother there is a sense of disgust when we find our bodies repeating her gestures, her aging-corporeal failings -- the particular lines of her crow's-feet, the specific topology of her flab. Imagine the horror of being a physiological copy of your mother, to be in effect imprisoned in her body! If, as the Freudians tell us, all children fear parental suffocation, a clone would live in a state of perpetual asphyxiation. For let us be clear: Cloning constitutes a form of possession, a monstrous act of invasion perpetrated on the material substrate of another human being.

I CANNOT IMAGINE THAT ANYONE WHO WOULD PUT a child in that position physiologically would easily let go of it psychologically. Twins who cannot let go face two possible fates: The first is the Identi-Kit life; the second is divorce. There is nothing sadder than a twin who has divorced his or her womb mate, but for some there is no other way to psychic freedom. And for some of those separated twins, divorce is synonymous with death. By mutual consent, June and Jennifer Gibbons had agreed that life together was untenable, and on the very day they were released from the asylum, Jennifer became mortally ill and died -- almost as if she willed it. In order that a clone might be free from the succubus of its parent, divorce or death may well be the only solution.

Defenders of cloning frequently argue that a cloned child would be a loved child. But love is precisely the problem, for in cloning we have the necrotic fruit of self-love. Jeremy Rifkin has famously defined genetic engineering as "cosmic masturbation -- man with his hands down his genes fiddling with himself." An act of genetic manipulation par excellence, cloning is the apotheosis of this masturbatory fantasy. Mating with oneself, cloning constitutes the ultimate act of incest. And not without reason is incest tabooed in almost every culture on Earth.
