Widely panned arsenic life paper gets retracted—15 years after brouhaha

In all, astronomical media threw encountered earth reactions in 2010 and 2011. In 2012, Science published two studies refuting the assertion that GFAJ-1 incorporates Arsenic atoms into its DNA. External scientists have concluded that this is an end to alered arsenic, but not a deeply different form of life.

Retraction

But now, in 2025, he stimulated controversy once again; Thursday, Science announced that it retracts the study.

Some criticisms, such as Redfield, have applauded the move. Others questioned the calendar, noting that 15 years had passed, but only a few months had happened since the New York Times published a profile of Wolfe-Simon, which now returns to science after being perceived as a pariah. Wolfe-Simon and most of his co-authors, on the other hand, continue to defend the original paper and protest against the retraction.

In a blog post on Thursday, the editor -in -chief of science, Valda Vinson, and the editor -in -chief Holden Thorp explained the withdrawal by saying that the criteria of science to issue a retraction since 2010. At the time, it was reserved for allegations of misconduct or fraud, but can now include serious defects. More specifically, Vinson and Thorp referred to the criticism that the bacteria genetic material was not correctly purified of the background before its analysis. While stressing that there was no suggestion of fraud or fault on the part of the authors, they wrote that “science considers that the key conclusion of the article is based on erroneous data”, and it should therefore be retracted.

Jonathan Eisen, an evolving biologist at the University of California in Davis, criticized this decision. Addressing the team of new sciences, which is independent of the review branch of the journal, Eisen said that despite being critical of the 2010 article, he thought that the discussion of controversial studies should take place in scientific literature and not rely on subjective decisions by publishers.

In an element attached to the notice of retraction, the authors also dispute the retraction by saying: “Although our work could have been written and discussed more carefully, we support the data as indicated.

One of the co-authors, Ariel Anbar, a geochemist on Arizona State University, told nature that the study had not had any mistakes but that the data could be interpreted in different ways. “You do not retract due to a dispute on data interpretation,” he said. If this was the case, “you must remove half of the literature.”
