The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print.
The paper was titled “Mineralized Tissue Formation by Bone Morphogenetic Protein-7–transfected Pulp Stem Cells“. According to the notice: Read the rest of this entry »
Back in April, a group of French and Tunisian researchers published a paper in Biomaterials which came to the astonishing conclusion that buckyballs
(carbon tetrachloride) coated in olive oil could dramatically extend the lives of lab rodents. That news was picked up by Derek Lowe’s In the Pipeline blog, on which he expressed some bemusement about the work but ultimately praised it:
These are reasonable (but unproven) hypotheses, and I very much look forward to seeing this work followed up to see some more light shed on them. The whole life-extension result needs to be confirmed as well, and in other species. I congratulate the authors of this work, though, for giving me the most number of raised eyebrows I’ve had while reading a scientific paper in quite some time.
One of those eyebrows dropped a bit the following day, when Lowe reported that readers had pointed him to a clear case of image duplication in the article. At the time, Lowe concluded: Read the rest of this entry »
