There is exciting news in the fight against Alzheimer's. Researchers in South Korea say their studies show that stem cells may someday be able to help prevent or treat the disease. Researchers there say they have drastically improved the learning abilities and memory of mice suffering from Alzheimer's by taking stem cells from the fat of adult mice, and injecting it into their veins. The scientists explain that since the stem cells are pulled from the animal's own fat, the body doesn't reject it, and it eliminates ethical concerns. They hope to have clinical tests complete within three years.
