Scientist cleared of falsifying results

An investigation into scientist Han Chunyu, who was forced to retract a paper he wrote about a groundbreaking gene-editing technique after allegations of fraud, has concluded that he did not intentionally falsify his research.

The news triggered some skepticism and debate online regarding academic integrity.

Han's employer, Hebei University of Science and Technology in Shijiazhuang, Hebei province, said it had joined with third-party labs to conduct thorough investigations and repeated experiments regarding the data and findings presented in the paper, according to a short online statement released on Friday night.
