    In academia, manuscripts serve as an important component of career development. The past several years have seen heightened evaluation of the role of the gender gap in career advancement, as well as other bibliometric changes in publications. We therefore analyzed authorship and publication trends in the Annals of Biomedical Engineering over the past three decades (one complete year of manuscripts for each decade; 1986, 1996, 2006, and 2016). The variables analyzed were number of authors per manuscript, numerical position of the corresponding author, number of collaborating institutions and countries, number of references, and number of citations per manuscript. The gender of both the first and corresponding authors was identified and analyzed over time and by region. Globally, the percentage of female first and corresponding authors significantly increased from 0% in 1986 to 28.6% (p = 0.003) and 20.4% (p = 0.0009), respectively, in 2016. Although there were significant differences regarding female first and corresponding author over time, they did not vary by region of origin (p = 0.5 and 0.2, respectively). Overall, these findings highlight the improvements made and the challenges that still exist related to publishing within the bioengineering field.

    Skeletal adaptations in young male mice after 4 weeks aboard the International Space Station
    (Nature Research, 2019-09-24) Maupin, Kevin A.; Childress, Paul; Brinker, Alexander; Khan, Faisal; Abeysekera, Irushi; Aguilar, Izath Nizeet; Olivos, David J., III; Adam, Gremah; Savaglio, Michael K.; Ganesh, Venkateswaran; Gorden, Riley; Mannfeld, Rachel; Beckner, Elliott; Horan, Daniel J.; Robling, Alexander G.; Chakraborty, Nabarun; Gautam, Aarti; Hammamieh, Rasha; Kacena, Melissa A.; Orthopaedic Surgery, School of Medicine
    Gravity has an important role in both the development and maintenance of bone mass. This is most evident in the rapid and intense bone loss observed in both humans and animals exposed to extended periods of microgravity in spaceflight. Here, cohabitating 9-week-old male C57BL/6 mice resided in spaceflight for ~4 weeks. A skeletal survey of these mice was compared to both habitat matched ground controls to determine the effects of microgravity and baseline samples in order to determine the effects of skeletal maturation on the resulting phenotype. We hypothesized that weight-bearing bones would experience an accelerated loss of bone mass compared to non-weight-bearing bones, and that spaceflight would also inhibit skeletal maturation in male mice. As expected, spaceflight had major negative effects on trabecular bone mass of the following weight-bearing bones: femur, tibia, and vertebrae. Interestingly, as opposed to the bone loss traditionally characterized for most weight-bearing skeletal compartments, the effects of spaceflight on the ribs and sternum resembled a failure to accumulate bone mass. Our study further adds to the insight that gravity has site-specific influences on the skeleton.
