Recently we did a post on a new method of creating induced pluripotent stem cells, which does not require either destroying embryos or genetic engineering, only a bath with certain chemicals. This breakthrough caused great excitement around the world.
And quite surprising many scientists around the world have started to replicate the Japanese experiment. Unfortunately, until now without success. However, many scientists working in this field are, as yet, still reluctantly to call this discovery a fraud. Instead many suggest that the Japanese have not unfold the whole procedure, possibly due to a patent application.
Nature, the journal which has published the Japanese research, is now investigating the integrity of the scientists who wrote the article. We believe that this is a good thing, though we hope that the researchers will be found integer, after all extraordinary claims require extraordinary evidence.
