This is a major breakthrough. Scientists have managed to create stem cells ("building block" cells that can be turned into any cell) from skin tissue. This means that embryos do not need to be used, which proved controversial. George Bush was very much against this and this new breakthrough will mean that it is easier for scientists to research new disease cures, as limitations were placed on them previously.

The stem cells themselves can't be used directly in people because they were created by a virus that could pose a risk to people, but they can be used for research purposes in mice. They are working on refining the method so that they can be used with people. They have a lot of uses from repairing damaged organs and tissue to reversing ageing (which is a little scary).

I'm pretty sure that this will win the Nobel Peace Price next year because of the implications of this discovery.

Yeah, Bush will be all over this saying, "See? I did something right! Told ya we didn't need embryonic stem cells, nyaaa nyaaa"

But he's still wrong. Check this out:

QUOTE
The technique isn't likely "to bear any fruit," said Tom Okarma, president and chief executive of Geron Corp. (GERN), a California biotech drug developer that has spent $100 million on human embryonic stem cell research.

"Most of the people who are doing this work and make the claim that this is going to change the therapeutic field really know nothing about cell therapy," Okarma said.

The scientists who pioneered the new approach have said that reprogramming an individual's own cells to mimic stem cells provides a way to create individually tailored transplant tissue unlikely to be rejected by that person's immune system.

But the process of getting the FDA to approve personalized treatments for medical use would ultimately prove far more expensive than using tissue grown from embryonic cells, Okarma said.

I don't think it's an issue of expense.... it seems clear to me that the future of medicine lies in tailoring the treatment to fit the person, and at any rate, the government is more likely to subsidize this new treatment over the other one. This guy has spent $100 million on the alternative; of course he's going to be biased.

OK then, would you believe what other scientists are saying?

"Hurdles remain for new stem cell technique
Years of study needed before we see payoffs for patients"

About the only immediately positive thing that I can see is that federal money for research on the new technique won't be a problem.

Oh yeah, I wasn't saying it would change anything instantly. When it comes to medical stuff, it has to go through years or even decades of refinements, testing, licensing, etc. It will be a while before it can be used in people BUT there is no reason why it can't be tested today in mice or used to grow diseases in a dish. Disease-growing may help find non-stem cell treatments for diseases that could be in use within 5 years. The possibilities are endless even before it is licensed by the FDA as a treatment.

Regardless this is great news. But I just thought of something. If scientists do actually find cures to all these diseases, they should pass a law saying that Republicans cannot benefit from them. Since they are all against stem cells being used. That way the democrats will outlive them and the world will be a better place.
