...indeed possible to take a skin cell from an adult patient and tweak it to revert to an embryonic-type cell, that would mean that any patient needing a stem-cell-based treatment could, in theory, heal himself. Last year, Yamanaka was the first to announce success with this approach, by exposing the cells to four growth factors and nutrients. But the stem cells he generated were genetically abnormal and unstable. Building on the initial technique, Yamanaka's group, as well as those led by Rudolph Jaenisch at Whitehead and Konrad Hochedlinger at HSCI, showed that the process does indeed...
...that the scientists turned back time on the mouse skin cells. They used a retrovirus vector, piggybacking the genes for the growth factors and proteins onto this infectious ferry. Retroviruses, however, like HIV, can cause infectious diseases and are not always easy to control, so before testing this approach in humans, researchers need to find other modes of transport for the critical compounds. The good news is that they need the genes to churn out their proteins for a only brief period of time, so using less virulent viruses, such as the adenovirus (responsible for the common cold) or simply...
...five Harvard seniors say they have sought mental health treatment while in college, according to the results of a survey conducted by The Crimson. The results provide new insight into the extent of the campus mental health crisis—three years after Harvard overhauled its approach to therapy and treatment. The survey results could help to clear “misperceptions” regarding mental health at Harvard, says the College’s mental health chief, Paul J. Barreira. “There’s a discrepancy between behavior and perception,” says...
...After arriving in Baghdad, Feldman played a critical role in the writing of Iraq’s new constitution. Feldman says that while most of the advisers argued for a secular constitution, he contended that such an approach would not be realistic...
...February that “I certainly got an earful” from the Undergraduate Council on issues ranging “from recreational facilities to internship opportunities to social life.” But Faust, who has never overseen undergraduates as an administrator, voiced ambivalence about how to approach those issues...
