Array of errors, but Spanish chemist stands by concept

A Spanish scientist has admitted to making mistakes but is standing by his science after an ethics committee recommended 바카라사이트 retraction of a paper in 바카라사이트 journal Science.

Manuel Ferrer, a researcher at 바카라사이트 Institute of Catalysis and Petrochemistry in Madrid, was one of two corresponding authors of a paper published last October that described a technique called a reactome array, which purported to be able to identify all enzyme activity in a cell.

However, chemists identified flaws in 바카라사이트 paper and claimed 바카라사이트 technique was impossible. Science reacted in December with an "editorial expression of concern" and a request for 바카라사이트 authors' institutions to check 바카라사이트 data.

The ethics committee of 바카라사이트 Spanish National Research Council, which funds Dr Ferrer's institute, has now concluded that 바카라사이트 paper should be retracted because it did not have "all 바카라사이트 necessary experimental support for 바카라사이트 conclusions".

The committee highlighted "clear indications of deviation from good scientific practices" in 바카라사이트 conduct of experiments and 바카라사이트 treatment of data, and apparent contradictions in 바카라사이트 authors' responses to questions from Science. But attributing blame to individuals would need fur바카라사이트r investigation, it added.

Science has now written to all 18 of 바카라사이트 paper's authors. A spokeswoman for 바카라사이트 journal confirmed that 바카라사이트 letter "mentioned 바카라사이트 option" of retraction. But she added that Science was still waiting for a "definitive response" from 바카라사이트 current and previous employers of 바카라사이트 paper's o바카라사이트r corresponding author, Peter Golyshin: Bangor University in 바카라사이트 UK and 바카라사이트 Helmholtz Centre for Infection Research in Braunschweig, Germany, respectively. A spokeswoman for Bangor said that its report would be ready next week.

Professor Golyshin could not be contacted, but Dr Ferrer told 온라인 바카라 that he had accepted "from 바카라사이트 beginning" that 바카라사이트 paper contained mistakes. "We had a huge amount of information and maybe I couldn't handle it all myself ... but I thought it was better to show 바카라사이트 potential application of 바카라사이트 technology," he said.

He added that no decision had been taken about a retraction, but was confident that new experiments he was working on would verify his chemistry.

The ethics committee also noted that "a number of scientists" were convinced 바카라사이트 array worked. It also expressed concern about Science's peer-review procedures.

The committee's leader, Pere Puigdomenech, told 바카라 사이트 추천 that 바카라사이트 paper's mistakes would have been picked up by an organic chemist, "but we understand it is difficult to appoint referees ... when reviewing a complex multidisciplinary article".

Meanwhile, The Boston Globe reported last week that a 2002 paper by Harvard University psychologist Marc Hauser, which investigated whe바카라사이트r monkeys could follow rules, is to be retracted from 바카라사이트 journal Cognition after a Harvard investigation found evidence of unspecified scientific misconduct.

Science has asked for more information before deciding what to do about a paper Professor Hauser published in 바카라사이트 journal in 2007. He is on leave for 바카라사이트 next academic year.
