pnas juneThe Proceedings of the National Academy of Sciences (PNAS) lifted the embargo early yesterday on a paper because of an embargo break — the ninth time this year they’ve had to do that.

Here’s what went to the journal’s press list yesterday afternoon, days before the embargo was scheduled to lift on Monday afternoon:

Due to an embargo break, PNAS is lifting the embargo early on the following paper. All other articles are under the scheduled embargo:

  • Obesity and accelerated liver aging

Using DNA methylation as a biomarker to determine the epigenetic age of liver tissue in 137 humans, a study finds that liver age is accelerated by 3.3 years for each 10 units of body mass index above normal, potentially explaining the high incidence of age-related illness in individuals with obesity.

PNAS tells Embargo Watch that

The author’s institution posted a press release without the embargo date and time.

I also asked if the journal was concerned about the large number of breaks this year. The journal said:

We investigate embargo breaks on a case-by-case basis.
