That's a Lot of Ink

Duncan Hull at O'Really? contemplates the number of scientific journal articles that have been published over the last 350 years. PubMed, the blogger notes, has more than 19 million citations — "around one paper per minute is added to this database (on average)," he adds. "But even this enormous database excludes large swathes of published articles in physics, mathematics, chemistry, engineering and computer science not deemed 'worthy' of indexing by the United States National Library of Medicine," Hull writes. Scopus and ISI Web of Knowledge both claim to have indexed more than 40 million records, he notes, though Google Scholar doesn't list its index size. The University of Ottawa's Arif Jinha puts the estimate at about 50 million articles since 1665, Hull says. To put this figure into perspective, consider that many manuscripts as "one paper for every base-pair in human chromosome Y," or "one paper per tweet at twitter on an average day in 2010," he says.

In other absurd publishing news, Chuck at Lounge of the Lab Lemming asks — hypothetically, of course — if it's wrong to "cobble together a 40 page manuscript that doesn't quite make sense, submit it to a journal under a false name and address, and recommend three people you really don't like to be the reviewers?" The Daily Scan has no comment.

Study Finds Sorghum Genetic Loci Influencing Composition, Function of Human Gut Microbes

Focusing on microbes found in the human gut microbiome, researchers in Nature Communications identified 10 sorghum loci that appear to influence the microbial taxa or microbial metabolite features.

Treatment Costs May Not Coincide With R&D Investment, Study Suggests

Researchers in JAMA Network Open did not find an association between ultimate treatment costs and investments in a drug when they analyzed available data on 60 approved drugs.

Sleep-Related Variants Show Low Penetrance in Large Population Analysis

A limited number of variants had documented sleep effects in an investigation in PLOS Genetics of 10 genes with reported sleep ties in nearly 192,000 participants in four population studies.

Researchers Develop Polygenic Risk Scores for Dozens of Disease-Related Exposures

With genetic data from two large population cohorts and summary statistics from prior genome-wide association studies, researchers came up with 27 exposure polygenic risk scores in the American Journal of Human Genetics.
