Tokyo panel calls for retraction of 43 Kato papers

with 7 comments

katoThe University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.

Hosalkar became embroiled in a messy affair after problems surfaced in data he had published while at Rady Children’s Hospital — a facility he left under a cloud of recriminations. More on that in a bit. Read the rest of this entry »
