The most featured research
  1. Medical and health research topped the list with 44% of sharing across mainstream and social channels. The most popular ranged from topics such as the effect of artificial sweeteners on glucose intolerance to the origins of the Ebola virus
  2. Biological sciences accounted for 20% of the Top 100. Articles in this category included controversial (and later disproven) studies on the creation of human stem cells in acid baths, and many others focussed on the ancestral genomes of humans and animals.
  3. Physical sciences ranked third with 9% in total from these areas of study – the most popular of which was a new theory on the nature of black holes from renowned Professor, Stephen Hawking.


International Collaboration

US research leads the way; UK led projects show close links to American scientists

  • 80% of articles in top 100 which named a British author were the result of international collaborations
  • 85% of those collaborations included contributions from researchers in North America
  • 27% received input from researchers in Central or South America, the Asia Pacific region, or Africa
  • 37 (or 54%) of the 68 US outputs listed were produced by only US based academics
  • Collaborations with researchers in Central or South America, the Asia pacific region, or Africa were found in just 14 (20%) of articles that also featured a US author.



Euan Adie, Founder of Altmetric, said of the Top 100: “We continue to see a significant increase in the volume of research being shared and discussed online, and in the audiences engaging in those conversations. It’s no surprise to see that the most shared articles of the year heavily mirror the media agenda, but interesting to note that on occasion online communities are drawing attention to studies that have not received a significant amount of mainstream coverage.

“For example, we had more than 2,000 tweets for a study on how gaining basic certification affected nursing confidence levels. This reached a combined following of more than 2.2 million followers, demonstrating how social media can really boost the profile of some online published studies.”


Data was collated from November 14th 2013 to 14th of November 2014, for articles publisher from November 2013 onwards. Editorial, comment, review and other non-original research content is excluded. Author and institutional data was collected from PubMed, or from the original article page if there was no associated PubMed record. Altmetric scores shown were captured at the time of collation, and may have changed slightly since.
