...Health Science Center at San Antonio and one of three lead authors of the study. But he and his colleagues were prompted to test the aging effects of rapamycin, which was discovered in Easter Island soil samples about 40 years ago, after noting that the compound appeared to affect cell growth in lab animals in much the same way as calorie-restricted diets, which also appear to extend life.

...like seeing people who had died," Abramova says, of finding the hulking section that once wrapped around the central nervous system of the 154-ft. (47 m) sub. Abramova's father and uncle, like so many men in this city pockmarked with Khrushchev-era apartment blocks and cell-phone billboards, were once submariners. (Read: "The Second Revolution...
...brouhaha kicked off on July 8, when the Guardian published a report citing an unnamed "senior source" at Scotland Yard as saying that News International had settled three cases out of court. Those cases allegedly demonstrated that its journalists had worked with private investigators to hack into the cell-phone messages of "two or three thousand" people to obtain data related to bank statements, phone bills, social-security records and taxes. Among the public figures the Guardian claims were targeted are former Deputy Prime Minister John Prescott, London mayor Boris Johnson and actress Gwyneth Paltrow. (See pictures of London...
That's how long it took Nayernia's team to nurture sperm from embryonic stem cells, using a special cocktail of growth factors, nutrients and retinoic acid, a derivative of vitamin A. It is worth noting that researchers could generate IVD sperm only from male embryos; when they tried using stem cells from a female embryo, they were unable to get sperm to mature past the spermatogonial stage. That suggests that genes located on the Y chromosome, which female cells do not contain, may be essential for triggering the maturation of the primitive sperm cell...
That might seem more like science fiction than reality, but given the pace of stem-cell research, it may not be that far off. "We have the potential therapeutic use of a technology that pushes the boundaries of what people feel comfortable with ethically," says Hyun. With more advances like this one likely to come in months if not weeks, that comfort level will have to catch up quickly...
