Everything about Shinya Yamanaka's discovery was right-except for the timing. The 44-year-old Kyoto University stem-cell researcher had found a way to genetically reprogram an ordinary mouse skin cell to revert to the virtual equivalent of its embryonic state, in which it has the potential to grow into any kind of tissue. The finding was a promising first step toward the creation of stem-cell lines for near-miraculous medical treatments-and because Yamanaka did not use human embryos, his technique offered researchers everywhere a way to sidestep the ethical controversies that have dogged the field...
...cells destroyed by disease or injury, without fear of immune-system rejection. Experts were quick to warn that significant hurdles remained before the technique might ever be used in people, but the sheer simplicity of Yamanaka's discovery-he found just four genes were required to reprogram the mouse skin cells-was cause for elation. "This is great science," says Alan Trounson, professor for stem-cell sciences at Monash University in Melbourne, Australia. "It takes us a big step closer to reprogramming adult cells...
...admire Al Gore for two reasons: not only is he smart enough to turn away from the world of self-aggrandizement in which politicians live, but also the picture of his home office in Nashville saved my skin. When reprimanded for the umpteenth time by my wife that I should get my home office in order, I triumphantly waved the article and picture under her nose. For once, she was at a loss for words.

According to the Centers for Disease Control and Prevention, more than 70% of the bacteria that cause infections in hospitals are resistant to at least one antibiotic. Methicillin-resistant Staphylococcus aureus (MRSA), which causes boils or pimples on the skin, is only the latest superbug to make the rounds and has appeared in dozens of high school and college athletic locker rooms, as well as in three NFL locker rooms. Drug-resistant tuberculosis cases, including those of the variety affecting Speaker, have risen along with peaks in AIDS cases, as people with weakened immune systems are especially vulnerable to infection...
