Scientists who share data publicly receive more citations

Summary:
A new study finds that papers with data shared in public gene expression archives received increased numbers of citations for at least five years. The large size of the study allowed the researchers to exclude confounding factors that have plagued prior studies of the effect and to spot a trend of increasing dataset reuse over time. The findings will be important in persuading scientists that they can benefit directly from publicly sharing their data.

A new study finds that papers with data shared in public gene expression archives received increased numbers of citations for at least five years. The large size of the study allowed the researchers to exclude confounding factors that have plagued prior studies of the effect and to spot a trend of increasing dataset reuse over time. The findings will be important in persuading scientists that they can benefit directly from publicly sharing their data.

The study, which adds to growing evidence for an open data citation benefit across different scientific fields, is entitled "Data reuse and the open citation advantage." It was conducted by Dr. Heather Piwowar of Duke University and Dr. Todd Vision of the University of North Carolina at Chapel Hill, and published today in PeerJ, a peer reviewed open access journal in which all articles are freely available to everyone.

The study examined citations to over ten thousand articles that generated new gene expression data, a quarter of which had data publicly archived in the GEO and ArrayExpress repositories. Papers with publicly available data received about 9% more citations overall, with the difference increasing over time. The researchers concluded that much of this citation difference was due to actual data reuse.

"Professional advancement in science is still highly dependent on how well your paper gets cited, even in a field like genomics where the data underlying that paper may have far more scientific impact over the long term." said Dr. Vision, a biologist affiliated with the National Evolutionary Synthesis Center and the Dryad Digital Repository. "Until the happy day when hiring and promotion committees catch up with how to value data sharing for its own sake, it is comforting to know that scientists can still receive credit for data sharing in a currency that counts."

The researchers also mined the full text of articles for references to dataset identifiers in order to study trends in data reuse directly. They took the unusual step of discussing the obstacles they encountered in the paper. Dr. Piwowar, at the time of the study a postdoc with the DataONE project, said "We need more open and cohesive infrastructure to support collecting evidence about the process and products of science. This evidence is needed to inform important policy decisions. For example, data archiving requirements, infrastructure, and education should be informed by evidence about how data is and is not reused."

The mined references revealed that scientists generally stopped publishing papers using their own datasets within two years, while other scientists continued to reuse their data for at least six years. It also showed that data reuse is on the rise. "Not only were the number of reuse papers higher," says Dr. Piwowar, "but analyses from 2002 to 2004 were reusing only one or two datasets, while a quarter of the studies by 2010 were using three or more."

Chameleon Camouflage to Give Tanks Cloaking Capabilities

Reuters - Innovations Video Online (Oct. 22, 2014) — Inspired by the way a chameleon changes its colour to disguise itself; scientists in Poland want to replace traditional camouflage paint with thousands of electrochromic plates that will continuously change colour to blend with its surroundings. The first PL-01 concept tank prototype will be tested within a few years, with scientists predicting that a similar technology could even be woven into the fabric of a soldiers' clothing making them virtually invisible to the naked eye.
