...bigger: a tip that Hwang's 2005 Science paper might contain fraudulent data. To verify the allegations, MBC requested samples of the stem cells, which Hwang provided. Pursuing their lead, the journalists tracked down two of three researchers from Hwang's lab who had gone to the University of Pittsburgh to work with his American collaborator and co-author, Dr. Gerald Schatten. They tried to strong-arm the Koreans into confirming the charges of data manipulation, and soon after, Schatten abruptly announced that he was terminating his partnership with Hwang, citing "information ... suggesting that misrepresentations might have occurred...
...retest, and to his surprise, he said, they were invalid. His theory: someone had switched the samples when they were at MizMedi to be photographed (his lab didn't have the right microphotography equipment) and stored. Later he accused Sun Jong Kim, one of the scientists cornered in Pittsburgh by MBC, of making the switch...
...turn, Kim has accused Hwang of asking him to forge the suspect photographs. Kim also says Hwang paid him a total of $30,000 (that Kim has returned to the university), which Hwang says was simply to cover Kim's living expenses in Pittsburgh. Korean press reports suggest that total payments to Kim and a colleague, Park Jong Hyuk, may amount to more than $50,000. These allegations are being investigated by Korean prosecutors...

For $25 billion, we could build new $90,000 homes for 275,000 households displaced by Katrina. Simple economics says New Orleans should not be rebuilt. Charlie Smith Pittsburgh, Pennsylvania...
...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...
