Technologized Reproduction in Space: A Space‐Bioethical Case for Assisted Procreation

open access: yesBioethics, EarlyView.
ABSTRACT With the increasing feasibility of space colonization, the issue of reproduction in space is becoming more relevant. As new settlements on the Moon, Mars, and other celestial bodies emerge, ensuring generational continuity will be essential for the survival and growth of these communities.

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

open access: yesJournal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Treadmill exercise within lower body negative pressure protects leg lean tissue mass and extensor strength and endurance during bed rest. [PDF]

open access: yes, 2016
Leg muscle mass and strength are decreased during reduced activity and non-weight-bearing conditions such as bed rest (BR) and spaceflight. Supine treadmill exercise within lower body negative pressure (LBNPEX) provides full-body weight loading during BR
