Several years ago, Chris Dames thought he had made an exciting discovery, a “secret sauce” that would allow him to design a device using a novel mechanism.
In a 2014 Nature Communications paper, Dames—who works at the University of California at Berkeley—and his team described the first experimental results for the device, a photon thermal diode. A thermal diode conducts heat in one direction but not in the other, and in theory, could have broad applications—for example, provide barriers that shield buildings from excess heat or use heat to power computers.
Recently, a biostatistician sent an open letter to editors of 10 major science journals, urging them to pay more attention to common statistical problems with papers. Specifically, Romain-Daniel Gosselin, Founder and CEO of Biotelligences, which trains researchers in biostatistics, counted how many of 10 recent papers in each of the 10 journals contained two common problems: omitting the sample size used in experiments, as well as the tests used as part of the statistical analyses. (Short answer: Too many.) Below, we have reproduced his letter.
Susana Gonzalez, a rising star in stem cell research, has had a rough year.
In addition to being fired from her former research institute (which she is now appealing), one of her grants (totaling nearly 2 million Euros) was suspended. Most recently, she has received two new retractions in Nature Communications over figure duplications and missing raw data. By our count, she has a total of three retractions.
Both of the new notices say the papers contained figures duplicated in other papers by Gonzalez, and neither includes Gonzalez among the list of co-authors who agreed to the retraction.
After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.
Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.
According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.
Two weeks after Nature Communications published a paper on asymmetric cell division in July, it posted a retraction notice saying the paper was submitted “without the knowledge or consent” of all but the corresponding author.
It’s not unusual to hear authors bemoan the fact that a new paper doesn’t cite their work that set the stage for a scientific advance. “The journal limited me to [a seemingly abitrary number of] references,” authors sometimes shrug, with or without apology. This week, however, we found a case of that which seems to have been resolved to everyone’s satisfaction.
The authors of a September 2013 article in Nature Communications have issued a correction for the piece, which failed to cite the source of a key step in their experiment.
