No. 1 news release on EurekAlert!'s 2020 Trending List smashes previous all-time record for visits

December 23, 2020

The most-visited news release on EurekAlert! in 2020 racked up just under 1 million hits - the most in the site's near 25-year history.

The University of California, Riverside release is one of three about brain health on the 2020 Trending list in a year when COVID-19 dominated headlines across the globe. It described a mouse study that showed soybean oil induced negative changes to genes affecting neurological conditions like autism and Alzheimer's disease. The news release registered an unprecedented 987,050 visits, surpassing the previous record set in 2017 for yearly total views of a single release by almost 10%.

EurekAlert! is an editorially independent, nonprofit news release distribution platform operated by the American Association for the Advancement of Science (AAAS) as a free resource to journalists and the public. News releases hosted on EurekAlert! are produced and submitted by research institutions and journal publishers and must meet eligibility guidelines for acceptance.

In the fourth most-visited release, Swiss and Italian scientists proved a link between low gut microbial diversity and Alzheimer's disease. Researchers from Tokyo Metropolitan University found a new enzyme mutation that impacts how proteins cluster in the brain and cause Alzheimer's disease in the ninth most popular release.

Three COVID-19-related news releases appear on the list, starting with the second trending release. It described a research review that pointed to a relationship between cardio exercise and protection against COVID-19 respiratory symptoms. Potential coronavirus mitigation strategies also featured in the third and seventh news releases, in the form of an anti-parasitic drug and vitamin supplements, respectively. Overall, approximately 13% of news releases accepted by EurekAlert! in 2020 were COVID-related.

Half of the 2020 Trending releases originated outside the United States and, for the first time, a news release from China, by the Chinese Academy of Sciences, made the top 10. It describes the bones of a small prehistoric rodent, unearthed in northeast China, that clarified the evolution of mammalian ear bone structure. Another paleontology release detailed a specimen of the carnivorous Allosaurus, discovered in Utah, that became the oldest known of its species in North America.

The unexpected (and undeniably cute) observation of wolf pups playing fetch was the topic of the fifth trending release about a study in iScience, a journal published by the release's submitter, Cell Press.

Trends described in the eighth trending release reflected men's shifting awareness and attitudes toward sexual health problems over the last 10 years, as presented at the 35th European Association of Urology annual congress.

Most Shared

Four news releases from the top 10 most visited list were also among the most shared, with the No. 1 release taking the top spot on both lists. COVID-19-related content, however, ruled the most-shared lineup overall, taking up four out of five spots with three news releases and one infographic. Facebook and Twitter were the two social platforms users preferred for sharing, accounting for 45,932 and 32,595 of 2020's total shares, respectively.

More than 34,000 news releases were accepted to EurekAlert! in 2020, making it the highest volume submission year in the platform's history. Research institutions, universities, journal publishers, and government agencies author and submit the news releases hosted on EurekAlert!. EurekAlert!'s editorial team reviews submissions against a set of longstanding eligibility guidelines prior to acceptance and dissemination to EurekAlert! reporter-members and the public.

The swell in news release submissions to EurekAlert! in 2020 partly resulted from coronavirus research. As a service to reporters and the public, EurekAlert! launched a COVID-19 online newsroom in April to house all pandemic-related news releases and multimedia. So far this year, more than 4,000 COVID-19-related news releases have been accepted, and the COVID-19 online newsroom has seen on average 19,600 visits per month since launching.

The 2020 Trending List was based on the number of views received by news releases accepted between December 16, 2019 and December 15, 2020.
