Twenty-five days. That's how long it took Dr. Shinya Yamanaka of Kyoto University to undo more than 30 years of exquisitely programmed biology packed into a woman's cheek cell - and just maybe change the world. In a procedure that some scientists thought could take decades to discover, Yamanaka tricked the cheek cell into acting like an embryonic stem cell - capable of dividing, developing and maturing into any of the body's more than 200 different cell types. And he wasn't alone: on the same day that he published his milestone in the journal Cell, James Thomson...
...Stem cells generated by this method are ideal not just because they are free of political and moral baggage. They can also be coaxed into becoming any type of tissue, and then be transplanted back into the donor with little risk of rejection. Still, these cells are far from ready for medical use. The viruses used to ferry the genes that manipulate the cells can introduce genetic mutations and cancer. And with myriad ways to reprogram a cell, sorting out the best ones will take time - meaning that stem cells from embryos will remain useful (and controversial) for a while...
...iPhone, but I plan to in the near future. Like Grossman, I'm sick of the sour grapes from naysayers who moan about what the iPhone doesn't do and ignore what it does do and just how well it does it. I hate my conventional cell phone with its 100-page, four-language manual that I can't begin to understand. I've used the iPhone without having to look at the manual. And the only language required is intuition. Brad Cathey, Wheaton, Illinois...
...RING Technophiles turned the retort into a ringtone. More than half a million people have downloaded it, generating more than $2 million in profits. While the tone struck a chord with Spanish cell-phone users, Venezuelans are also getting involved--some students are downloading the ringtone as a form of protest against Ch?...
...Neither Yamanaka nor Thomson believes their cells are quite ready for patients yet; for one, both methods use viruses to deliver the time-reversing genes, a practice that is acceptable in the lab but unsafe for the clinic. But the advances are finally pushing stem cell researchers to start talking about when, not if, stem-cell based therapies will be developed to treat diseases...
