Scientific American: Hwang down in flames
The fraud of Hwang was revealed BY his co-workers TO third parties (such as PD Notebook), who were the ones doing the catching. Beardsley neglects to mention the stiff price paid by PD Notebook and the co-workers. Further, the Korean authorities did a much better job of rapidly uncovering this fraud than did Bell Labs with Jan-Hendrik Schon.
Although she alludes to Hwang blaming others as an excuse to cover up his own failings, it may well be that others are committed malfeasance. This story is a lot more complex than simply saying Hwang did something bad and he got caught by other scientists.
Truly mediocre reporting by Scientific American.
