PIXABAY, OPENCLIPARTVECTORSPapers that call out issues in other papers appear to have little impact on the number of citations a given article receives. And highly cited papers tend to receive the bulk of such negative citations. That’s according to researchers who analyzed papers published in the Journal of Immunology between 1998 and 2007. The team published its results in PNAS this week (October 26).
“The results make sense and fit with what I expect,” said Gonçalo Abecasis of the University of Michigan in Ann Arbor who was not involved in the work. “Usually, when you take the time to write and say, ‘These [researchers] got it wrong,’ you do it with reference to papers that are otherwise high profile and that people think are probably good.”
“This piece is the harbinger of things to come—that by combining really large data sets with new analytical techniques such as machine learning, we can derive meaning from those article pairs that are linked via citation,” Abecasis added.
WIKIPEDIA, REGENTS OF UNIVERSITY OF MICHIGAN MEDICAL SCHOOLDo they or don’t they produce cardiomyoctes? That’s what researchers studying cKit+ cells have been asking for years, generating mixed results. According to the latest study, published this month (October 5) in PNAS, researchers from the University of Miami Miller School of Medicine and their colleagues showed that, under the right culture conditions, cKit+ cells can produce these cardiac progenitors.
