pnas 14For the second week in a row, the Proceedings of the National Academy of Sciences (PNAS) lifted its embargo early after embargo breaks.

This week, it involved two studies. Here’s the email that went out to the journal’s media list at 11:25 a.m. Eastern today, some three and a half hours before the embargo was scheduled to lift:

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

  • Assessing the origin of vertebrate legs

An analysis of the pelvic girdle and back fin of Tiktaalik roseae, a close relative of modern tetrapods, provides new details on the evolutionary link between fish and terrestrial vertebrates, a study finds. Neil Shubin and colleagues examined five specimens of Tiktaalik roseae remains recovered in 2004, 2006, 2008, and 2013

  • Social class and adolescent obesity

Recent research has suggested that the childhood obesity epidemic has plateaued, but a study reveals that the overall trend in youth obesity rates masks a significant and growing class gap between youth from upper and lower socioeconomic status (SES) backgrounds. Using data from two long-term national health surveys, the National Health and Nutrition Examination Survey and the National Survey of Children’s Health, Carl Frederick, Kaisa Snellman, and Robert Putnam show that obesity rates increased at similar rates for all adolescents between 1988 and 2002.

PNAS tells Embargo Watch:

We found stories in the Spanish newspaper Tribuna Salamanca (on the Tiktaalik paper) and the South China Morning Post (on the obesity and social class paper) that were published ahead of the scheduled embargo.
