Earlier this year, we reported on the retraction of a paper because of sloppy work by an outside lab. Now, we have the story of a retraction for “negligence” by a translator. Specifically, the author says the passages shared between the retracted 2015 vascular paper and another paper in EMBO Journal are a result of “negligence on the part of the translation company that I trusted to make my manuscript ready for submission.”
Quantum communication involves sending a series of photons in specific quantum states over fiberoptic cables. It’s a little like the 1s and 0s of traditional computing, but much more secure. If the photons are intercepted on their way to the intended target, the quantum states will change, and the recipients can know their information was accessed by other parties. This is especially interesting to governments with a lot of secret information to transmit: both China and the U.S. have programs to develop these networks.
The retracted paper was a discussion of how to efficiently send lots of quantum information from different sources through the same fiberoptic cables at once.
The authors of a study published last year looking at the effects of cell phone exposure on mice in utero have corrected a figure after it was questioned. New experiments, they write, confirm the original conclusions they drew from the figure.
It was, as Nature News wrote last month, a story that “seemed too good to be true:”
Stem-cell transplant claims debunked
Transplant of induced pluripotent stem cells to treat heart failure probably never happened
Hisashi Moriguchi, a visiting researcher at the University of Tokyo, had claimed a result that would have put him years ahead of researchers toiling in stem cell research. But the claims were met with a great deal of doubt — to say the least — and the story began to unravel when Harvard, where Moriguchi said he’d done the work, denied it had ever taken place.
And as expected, the retractions have now started. Today, a Nature Publishing Group journal said they would be retracting two papers, “A therapeutic method for the direct reprogramming of human liver cancer cells with only chemicals” and “Successful cryopreservation of human ovarian cortex tissues using supercooling.” The notices for the Scientific Reports papers will both say the same thing: Read the rest of this entry »
