American scientist Frances Arnold, who won the Nobel Prize for chemistry, has retracted her latest paper.

Axar.az reports citing BBC.

Ms Arnold shared the prestigious award in 2018 with George P Smith and Gregory Winter for their research on enzymes.

A subsequent paper on enzymatic synthesis of beta-lactams was published in the journal Science in May 2019.

It has been retracted because the results were not reproducible, and the authors found data missing from a lab notebook.

Reproduction is an essential part of validating scientific experiments. If an experiment is a success, one would expect to get the same results every time it was conducted.

Ms Arnold came forward with the news herself on Twitter on 2 January.

"For my first work-related tweet of 2020, I am totally bummed to announce that we have retracted last year's paper on enzymatic synthesis of beta-lactams. The work has not been reproducible," she tweeted.

"It is painful to admit, but important to do so. I apologize to all. I was a bit busy when this was submitted, and did not do my job well."

That same day, Science published a note outlining why it would be retracting the paper, which Ms Arnold co-authored with Inha Cho and Zhi-Jun Jia.
