Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Cosmic Rays from the Nucleus of M87

open access: yes, 2003
© 2003 by Universal Academy PressThe unresolved nuclear region of M87 emits strong non-thermal emission from radio to X-rays, and this has been interpreted as jet emission from a misaligned BL Lac Object in the context of the Synchrotron Proton Blazar ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Correspondence between Leaky-box and Diffusion Models of Cosmic-Ray Propagation

open access: yesThe Astrophysical Journal
The leaky-box model and the attendant concept of path-length distribution of cosmic rays were invented in the mid-1960s. Even though versatile computational packages such as GALPROP and DRAGON with the diffusion approach are now available for analyzing ...

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment [PDF]

open access: yes, 2008
Any microbial life extant in the top meters of the martian subsurface is likely to be held dormant for long periods of time by the current permafrost conditions.
