...Before Dolly, no one thought it was possible to turn back time, especially where biology was concerned. Once a cell started on its march of development, nothing, absolutely nothing, scientists thought, could turn it around again. Dolly, the cloned sheep, proved this biological maxim wrong in 1996, when Ian Wilmut was able to coax an aging mammary cell to become an entirely new sheep by giving it a home in a hollowed-out egg. And since every scientific experiment just begets more experiments, Dolly's birth got researchers to wondering: If the egg can reprogram a cell, is it possible...
...answer is a resounding yes, as evidenced by two groundbreaking papers published on Tuesday. In the journal Cell, Shinya Yamanaka of Kyoto University reports success in turning back the clock on cheek cells from a middle-aged woman, while James Thomson of University of Wisconsin, the first to isolate human embryonic stem cells, achieved the same feat with foreskin cells from a newborn baby. The achievements completely reset the boundaries of the stem cell debate, because both groups generated cells that looked and acted like embryonic stem cells, but without the need for eggs, embryos or ethical quandaries about where...
...technique, however, called nuclear transfer, is a cumbersome process that requires a steady supply of high-quality donated eggs, and a deft hand to empty out the genetic contents of those eggs and replace them with the DNA blueprint from another, aging cell. The odds of success are pretty low, even in the hands of experts with years of experience...
...alumni tailgate area and at the end of the field, where empty vodka bottles littered the tables sponsored by final clubs. As Harvard’s football team crushed Yale, 37-6, outside the Yale Bowl a general sense of confusion was amplified by the failure of cell phone service. Attendance for the Game reached 57,248—over 4,000 people more than two years ago—according to the Harvard Athletic Department. “From what I’ve seen—and the alcohol I’ve drunk—it?...
When clustering does work, though, it's gold. Consider Yokkaichi, Japan, a city of 300,000 people that is the premier place to make NAND flash memory, which is used in cell phones and MP3 players. Sandisk, a Milpitas, Calif.-based company that designs, manufactures and sells memory cards, moved its manufacturing base there from Manassas, Virginia a few years ago, partly to be closer to Toshiba, a company it partners with. Yokkaichi already had the infrastructure for both manufacturing and for the large R&D outfit that goes along with making memory cards. "By having it all in close...
