The numbers didn’t add up.
Over and over, Daniel Yuan, a medical doctor and statistician, couldn’t understand the results coming out of the lab, a prestigious facility at Johns Hopkins Medical School funded by millions from the National Institutes of Health.
He raised questions with the lab’s director. He reran the calculations on his own. He looked askance at the articles arising from the research, which were published in distinguished journals. He told his colleagues: This doesn’t make sense.
“At first, it was like, ‘Okay — but I don’t really see it,’?” Yuan recalled. “Then it started to smell bad.”
His suspicions arose as reports of scientific misconduct have become more frequent and critics have questioned the willingness of universities, academic journals and the federal government, which pays for much of the work, to confront the problem.
Eventually, the Hopkins research, which focused on detecting interactions between genes, would win wide acclaim and, in a coup for the researchers, space in the pages of Nature, arguably the field’s most prestigious journal. The medical school even issued a news release when the article appeared last year: “Studies Linked To Better Understanding of Cancer Drugs.”
What very few readers of the Nature paper could know, however, was that behind the scenes, Yuan’s doubts seemed to be having profound effects.
In August, Yu-yi Lin, the lead author of the paper, was found dead in his new lab in Taiwan, a puncture mark in his left arm and empty vials of sedatives and muscle relaxants around him, according to local news accounts — an apparent suicide.
And within hours of this discovery, a note was sent from Lin’s e-mail account to Yuan. The e-mail, which Yuan saved, essentially blamed him for driving Lin to suicide. Yuan had written to Nature’s editors, saying that the paper’s results were overstated and that he found no evidence that the analyses described had actually been conducted. On the day of his death, Lin, 38, the father of three young daughters, was supposed to have finished writing a response to Yuan’s criticisms.
The university had already fired Yuan in December 2011, after 10 years at the lab. He had been raising questions about the research for years. He was escorted from his desk by two security guards.
More recently, a few weeks after a Washington Post reporter began asking questions, a university spokeswoman said that a correction had been submitted to Nature and that it was under review.
“Your questions will be addressed with that publication,” a spokeswoman for the Hopkins medical school, Kim Hoppe, wrote in an e-mail.
Neither the journal nor the university would disclose the nature of the correction.
Hoppe declined an opportunity to have university personnel sit for interviews.
In the meantime, the paper has been cited 11 times by other published papers building on the findings.
