...study published today in the journal Cell Stem Cell, a team of Harvard researchers reveals that the dubious stem cells created by Korean scientist Woo Suk Hwang were indeed historic, just not for the reason that he originally claimed...
...world heralded Hwang, who reported that he had created the world's first human embryonic stem cells using a delicate cloning technique called somatic cell nuclear transfer (SCNT). If Hwang had actually done what he had claimed, he would certainly have brought stem-cell-based therapies closer to reality, by making it possible to develop patient-specific cells to treat diseases from diabetes to Parkinson's. Two years after his announcement, however, allegations of fraud led to an investigation by an independent committee of scientists, which failed to verify his findings, and Hwang and his feat were discredited; last year...
...study, led by Dr. George Daley at the Children's Hospital in Boston, shows that Hwang's stem cell line contains the first human cells to be generated not through SCNT, but through a process called parthenogenesis, sometimes referred to as virgin birth, since development is sparked spontaneously from the egg alone, rather than from the union of egg and sperm. Parthenogenesis is always a risk during nuclear transfer, since the process involves extensive manipulation of the egg and its nucleus. At the time that Hwang's original paper was published in Science, stem cell researchers raised the possibility that...
...talking about off the east coast of Thailand. It has great diving, she says, and lots of Chinese there so you don't have to worry about language. Her friend Vicky Yang is hunched over a borrowed laptop, downloading an e-mail from a pesky client on her cell phone. An actuary at a consulting firm, Vicky needs to close a project tonight. While she phones a colleague, the dinner-table conversation moves on to snowboarding ("I must have fallen a hundred times") to the relative merits of various iPods ("Shuffle is no good") and the sudden onrush of credit...
...lake complete with swimming dock and rope swing. The choice of activities at the camp is dizzying, from soccer to blacksmithing, from kayaking to watercolors, but no pastime is more popular than building forts of fallen tree limbs and poking at turtles in the creek. Leave your cell phones, laptops and iPods at home...
