After sequestering himself in a hospital psychiatric ward earlier this week, embattled South Korean cloning pioneer Woo Suk Hwang finally held a press conference on Friday. Before a packed room at Seoul National University, Hwang defiantly denied multiple allegations that he had fabricated the results of his history-making stem cell study published earlier this year in the journal, Science. During his lengthy statement, he blamed his compromised results on the possibility that his stem cell lines were switched at some point. He didn't elaborate on how or why the switch occurred...
...While Hwang defends his credibility, he admitted to making "a lot of mistakes" and being "negligent in maintaining the stem cells." He also asked Science to withdraw his paper because of these lapses may have compromised his data. Editors at Science confirmed that they have received requests from both Hwang and a co-author, Dr. Gerald Schatten of the University of Pittsburgh, to withdraw the paper. The journal requires all 25 co-authors to agree to a retraction, and Hwang said the remaining requests were forthcoming...
...Korean press. Several days after Schatten?s initial break with Hwang, Seoul?s news outlets cited a Korean government official and other sources in both Korea and the U.S., claiming that Schatten had met with Hwang in October and asked for 50% of the patent on the patient-specific stem cell cloning technique. Schatten also reportedly asked to be named chairman of the board of the newly created World Stem Cell Hub, a research center funded jointly by the South Korean government and private interests. The South Koreans reportedly denied his requests...
...Still, Hwang has a lot of explaining to do. He is already being investigated by his own university. And earlier this week, eight stem cell scientists, led by Dolly cloner Ian Wilmut, submitted a letter to Science, noting that ?accusations made in the press about the validity of the experiments published in South Korea are, in our opinion, best resolved within the scientific community... we encourage Hwang?s laboratory to cooperate with us to perform an independent test of his cell lines.? At stake, say the scientists, is the fledging field of stem cell science, which holds the potential...
...peace between the rival gangs the Crips and the Bloods, which helped lead to a drop in Newark’s murder rate. The killings Williams committed and the crimes his founding of the Crips caused are tragic and horrific. But the work Williams did in prison to help stem gang violence is laudable. Williams could have continued that work if his sentence had been commuted to life without parole. Instead, California killed Williams. The state did nothing more than prove to the youths Williams taught not to kill that death is sometimes the only acceptable punishment. Twenty-five years...
