The Pathogen Buzz of 2016

by Michelle Ziegler

Altmetrics recently released the Top 100 scholarly articles list for the year (captured on 15 Nov 2016). Their ranking captures the public discussion on academic articles judged by shares of the online edition, news articles, blog posts and tweets that include the digital object identifier code (doi). (So if you want to improve the Altmetrics number of your papers make sure that all blog posts/tweets/news articles have the doi somewhere.) Note that generating discussion is not the same as being the best papers produced. At least one one this list, on ‘Patient 0’ HIV-1,  seemed to generate a fair amount of complaints.

Overall, the list was dominated by medical and health science (49) and biological science (14), altogether being 63% of the top 100 articles. Some of the other categories are a little vague, such as physical science (6) vs. earth and environmental science (6) vs. material science (1). History and archaeology combined to produce only six of the top 100 and one of them, on the ‘Tully monster’, really should be paleontology (or biology?). We also have to keep in mind that Altmetrics misses most of the humanities journals. The Altmetric scores in the top hundred have also approximately doubled between 2014 and 2016. The lowest score in 2016 is 1605 and the lowest score in 2014 was only 746.

One highlight this year is that 47% of the top 100 were either freely available or open access. I noticed about midway through this past year that papers expected to get a lot of attention were often freely available or open access. The difference between freely available vs open access may be whether or not the authors had to pay for the open availability (?). I wonder if the freely available remain free forever, or only until the news dies down?

When it comes to pathogens, this year’s list comes with the distinctive buzz of a mosquito, Aedes aegypti, carrying this year’s emerging infectious disease, the Zika virus. Of the twelve papers directly related to infection, six are on Zika. Looking at the 2015 list, it’s clear that Zika put pathogens in the news this year. There are hardly no pathogen related papers in the 2015 list and in 2014, there were only five  – four on ebola and one on ancient Yersinia pestis. So clearly Zika has made a far bigger splash than even the much more lethal ebola.

Before we leave the buzz of 2016, we have to mention this year also saw the passing of Dr. Donald Henderson (1928-2016) who led the effort to eradicate smallpox. Henderson died in August; his obituary from the New York Times can be found here.
