Re:Born too late (Score:5, Informative)
Water freezes differently depending on how it's frozen. If you freeze it slowly it forms a crystalline structure that takes up a significantly larger space than before. That expansion is what ruptures the cells. However, if the water is flash frozen it doesn't form into crystals and takes up approximately the same amount of space as when unfrozen. That means that the cells remain undamaged. Flash freezing is the technique that is used in human cryogenics.

Let me start out by saying, I've lost a contact lens, so I apoligize for the spelling in advance. I'm having a hard time seeing. That said......
The Cold War wasn't the only arms race going on. There's one that exits every day inside each one of it us. It's a race between various pathogens and our immune system. Oddly enough, DNA plays a HUGE role in the functioning of the immune system as a whole.
Did you realize that the reason that African-Americans have sickle cell anemia is that it is an evolved immune response? In order to develop the disease, you must inherit 2 recessive "defective" genes. But if you have only 1 "defective" gene and one "normal" gene, you are immune to malaria. Malaria is a mosquito borne disease that kills more than a million people a year in Africa. My point with is that genes that seem to be "bad" to us, might only seem "bad" because we don't have the whole story.
We've spent either thousands or millions of years, depending on your point of view, on this planet with our pathogens. They change us and we change them. We know that this happens because we can sit in a labratory and observe it. Antibiotic resistant strains are a prime example of this. I happen to call it evolution. Just as wolves thin the deer herds, making them faster, smarter, and stronger, so must the wolves become faster, smarter and stonger to continue to catch the deer. When you consider the amount of time that we humans have spent living with our various bacteria, parasites, etc. , it's logical to me that is happing with us on a microscopic scale.
Genes are very complicated things because they encode all sorts of information about how you function an unbelievably basic level. There are genes that encode the proteins that make up the cell wall. There are genes that encode the proteins that make up the receptor sites in cell wall. And guess what, mine don't look or work like yours! So I'm near sighted. My whole family is near sighted. My whole family also lives to be a 100 and it's a nice healthly 100, too. I suspect that there is some correlation since the ones that aren't near sighted died in their late 80's and early 90's.
The tinkering with plants hasn't gone as well as most of the public has been lead to believe. They figured out how to make cotton that didn't need to be dyed. It grew as red or blue. Well, they released it. People planted it and now they are being sued. Their neighbors are getting all kinds of odd color combinations in what was supposed to be their white cotton. There's also a "pest resistant" corn. Now that the corn flea beetle and corn worm can't eat corn, what will they be going to go after next? Or, worse yet, will they evolve in to a superpest that can eat the "pest resistant" plants? If they can eat the "pest resistant" corn, will they be able to eat the other "pest resistant " crops we're getting ready to release. We've created other "superpests" and a whole host of other problems with our use of chemicals because we really didn't understand the ramifications of what we were tinkering with - DDT, DES, MRSA, STSS, and a whole alphabet soup of acronyms. These are just the ones I can name off the top of my head.
This is a really really good example of "Just because you CAN, doesn't mean you SHOULD". They don't understand what the side effects to the environment are with a simple thing like colored cotton. They sure aren't going to understand the full ramifications of making changes to humans any time in this century. Anybody that thinks that is a good idea, should probably get some IQ points spliced in to the DNS sequence.

Eugenics vs. Genetic Engineering (Score:5, Informative)
That may need a little elaboration, as the two touch on related areas.
Eugenics is a theory which holds that certain individuals are innately superior to others, and that the superior few are vastly outnumbered by the inferior many. If you accept these two premises, then it follows that the inferior many are sure to reproduce faster than the superior few, with the result that the characteristics of the superior individuals will be lost. Basically, a eugenicist sees the world in terms of a conflict between those with big brains and those with big dicks. In order to improve the species, therefore, a eugenicist will attempt to discourage the inferior from procreating, and encourage the superior.
The biggest problem with this theory is figuring out how to tell who's superior and who's inferior. The answer depends on how you ask the question, and on what your beliefs are about what would constitute a "superior" human being. The Nazis believed that a certain physical type was superior -- blond hair, blue eyes, extremely fair skin, what they called "Aryan". They conducted experiments attempting to further these characteristics; for example they would take a pair of brown-eyed twins, and inject chemicals into their eyes in an attempt to change the eye-color to blue. This particular study was carried out at Auschwitz by Josef Mengele, the Angel of Death [crimelibrary.com].
If, on the other hand, you are an American eugenicist, what you do to separate the inferior and the superior is come up with the Intellectual Quotient Test and administer it to all schoolchildren. Those who do well are deemed fit, and allowed to do things like take college prep courses in high school. Those who are deemed unfit are only allowed to take classes in, say, technical arts, thereby preparing them for a lifetime working as drones in a factory. Also, you get laws passed in many states requiring the forced sterilization [go.com] of any person below a certain IQ level who attempts to reproduce. You might also conduct studies such as the Tuskegee Syphilis Experiments [npr.org] which were begun with the understanding that the subjects would be black because black men are naturally more lascivious than white men, and therefore more likely to have syphilis. These experiments were funded by Congress, continued for four decades, involved hideously painful procedures like spinal fluid taps, and worst of all the subjects were never told that they had syphilis. By the time they found out, it was far too late for any of them to seek treatment.
Eugenics is no longer an accepted theory. It depends on an arbitrary vision of what constitutes "superiority", and led to some truly barbaric practices, both in Germany and in the United States. I do not know how well the theory was received in other countries. I am, however, truly grateful that it is no longer accepted.
Genetic engineering, on the other hand, is a technique for the modification of living creatures by altering their genetic structure. It could very easily be used for eugenics, but has other more benign purposes as well.
There are two kinds of genetic engineering. One involves the modification of an existing organism. For example, take a child afflicted with cystic fibrosis, a genetic disease which causes the lungs to fill with mucus, thereby making it extremely difficult to breathe. That child might be treated by inhaling a vapor of specially created viruses that insert themselves into the affected lung cells and alter their genetic code in such a way that they stop producing the mucus. This is also known as gene therapy [uiowa.edu].
The other form of genetic engineering involves modifying an organism before it starts growing. Thus you might take a fertilized egg and modify its DNA prior to its implantation in the wall of the mother's womb. Since all cells in the body ultimately derive from that egg, your modification would change the fundamental nature of the adult organism. Genetic modifications have been carried out on plants, for example to make them resistant to a particular disease, or to increase the per-acre yield of a food crop. You yourself have probably eaten such genetically modified food. It is quite common in America; less so in Europe, where there are a great many people who protest against it.
Genetic engineering is a field which has enormous potential for good -- the elimination of genetic diseases like cystic fibrosis. If two people are aware that their child might suffer from CF, they could perform an artificial insemination of an egg which had been "fixed", or avoid the disease simply by choosing an egg that wasn't affected in the first place. On the other hand, genetic engineering also has a staggering potential for abuse. A genetic engineer could not only cure diseases, but also create entirely new ones. The new disease might be used in biological warfare. It is conceivable (though currently not possible) that genetic engineering might be able to create a contagious mutagen -- a virus that would spread throughout the population, and make a particular modification within the bodies of the victims. Imagine if the Nazis had been able to create a virus that would alter the eggs and testicles of those who contracted it. They could have ensured that the next generation would be blond and blue-eyed, against the will of the parents.
Then, of course, there is the danger that we might screw up. We know a lot about genetics now, but there's even more that's not well understood. Sequencing out a full human gene doesn't mean that we understand how all the parts interact with another. There are large portions of the genome that don't seem to do anything (introns) . . . but then again maybe they do, and we just haven't figured it out quite yet. Then there's the fact that one sequence of DNA might control or contribute to three or four different finished structures. If you alter it to give a child green eyes, you might also cause the child to be bald. (That's just an example, I have no idea if the sequences controlling hair production and eye color are at all related.)
Basically, we don't know enough at this point to engage in wholesale manipulation of human genetics. We should not outlaw it -- the genie is out of the bottle, and if we tried outlawing it, the research would merely be undertaken by unethical scientists with little or no oversight. On the other hand, we should NOT perform modifications of human beings without a clear idea of what we're doing and a damn good reason to do it. Giving your kid a particular eye color is NOT a good reason for genetic engineering. Avoiding cystic fibrosis is acceptable. Engineering for more abstract qualities -- musical talent, mathematical skill, linquistic ability -- should be avoided at all costs until we have some idea what the hell we're doing. We don't even know if those qualities are controlled by genes; in the process of trying it out we might very well screw up and make some truly horrible mistakes. Note that many autistic people are also extremely good at math.
Then there are the social issues. Genetic engineering is expensive. If we're not careful, it could become a way for the wealthy to reinforce their dominance over world affairs. It is natural to want to give your child every advantage in life that you can; but doing so can simultaneously disadvantage other people's children.
In short, genetic engineering of humans is problematic. It could provide some unparalleled benefits to the human species . . . but it is also an ethical minefield, and could easily be turned to selfish or downright evil purposes.

Eugenics was adopted in most major Western nations. The United States more or less led the way, Britain, Canada, several other countries soon followed. What's interesting to note here is that Germany actually came into the game extremely late compared to the rest of the Western world, and that the Eugenics laws in Germany were formed and passed before the instatement of the Nazi party. The Nazis just happened to take it up with a vengance.
A little history for the crowd: Eugenics rose from the ideas of Social Darwinism, which of course rose from Darwin's ideas of evolution, though Darwin was rather appalled by Social Darwinism and never supported it at all. Social Darwinism took the ideas of evolution and applied them to society. The idea was that society, like nature, would become increasingly better over time, by nature of evolution. Those who fit in well with society and contributed would help advance society, and those who were a drag on society would fall by the wayside, and the ideas taken on by society would evolve and become better, closer and closer to perfect. This caused great hope amongst the people - don't worry, there's nothing bad around the corner, because society will continue to get better indefinitely. Talk about cheery ideas.
Then someone had the bright idea of meddling. We cull our herds, we cull our crops. We breed the best with the best to make even better, don't we? Why shouldn't we do that to humanity? We'll take the best and brightest and encourage them to reproduce, often, and we'll... well, we'll cull the sick and useless from the herds so they don't taint the stock. And so they did. Eugenics laws involving sterilization of the sick, the feeble-minded, the low of society, were passed, and how. Leilani Muir [google.ca] is a perfect example. An Albertan girl, 'feeble minded', she was sterilized. Today, her IQ is measured at around the 90's, I believe, and she's perfectly capable of functioning in society. They didn't care. It was for the glory of society.
Eugenics laws were gleefully adopted by everyone... Then World War II came. The Nazis came, and they took Eugenics to the logical extreme, and the world watched in horror at what lay at the end of the path they all had decided to travel down. Laws were thrown out, lawsuits were filed, and everything went to shit. People realized that ideal society was something we'd have to work towards, that there was no free ride. Supposedly. Some governments, including some in Canada, took as late as the 1970s to repeal their Eugenics laws, even though they weren't being used. Sad, but at least it happened.
So, for anyone who thinks that racial superiority and the like was born with the Nazis, think again. Canadians, Americans, Britons, we're guilty, because we started it. The Nazis took it to the extreme all at once, but I fear that if they hadn't been so quick about it, that might've been the way the rest of our societies went.

The real stuff is approximately $25 000 (US) per gram, which will treat 25 mice for a month, or one human for a day.
The problem with gene therapy is that it isn't available "now or soon", as stated in the article. The problem is that when the gene is injected, only a very small percentage of the muscle cells will express it. This means that delivery of the gene is very inefficient.
Adding onto this, there will be an immune response to the gene or the vector delivering the gene. This means that it won't hang around very long.
Next, there is a massive area to deliver to (all your skeletal muscle). And no efficient mechanism by which to accomplish this.
Basically, gene therapy is far from being a reality, let alone a mass market one that you could afford. To worry about gene doping at any Olympics in the forseable future is exceedingly premature.
The reason you can alter genes in mice is that their eggs can be manipulated in vitro . The manipulated eggs are artificially fertilized and injected into a pseudo-pregnant female. And while with this approach, only one cell has to be targetted, it still takes many many many months to create a transgenic mouse that expresses the proper genotype. Once that's done, you have to breed them - that's a lot of ass work for post-docs and PhD students.
