The EXO-UV program: lastest advances of experimental studies to investigate the biological impact of UV radiation on exoplanets
Ximena C. Abrevaya, Petra Odert, Oscar J. Oppezzo +4
The EXO-UV program is an international, interdisciplinary collaboration between astrophysicists and biologists aimed at expanding the characterization of ultraviolet radiation (UVR…
Protective Effects of Halite to Vacuum and Vacuum-Ultraviolet Radiation: A Potential Scenario During a Young Sun Superflare
Ximena C. Abrevaya, Douglas Galante, Paula M. Tribelli +16
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites. In this stu…
Radiation as a Constraint for Life in the Universe
Ximena C. Abrevaya, Brian C. Thomas
In this chapter, we present an overview of sources of biologically relevant astrophysical radiation and effects of that radiation on organisms and their habitats. We consider both…
Comparative Survival Analysis of Deinococcus Radiodurans and the Haloarchaea Natrialba Magadii and Haloferax Volcanii, Exposed to Vacuum Ultraviolet Irradiation
Ximena C. Abrevaya, Ivan G. Paulino-Lima, Douglas Galante +4
The haloarchaea Natrialba magadii and Haloferax volcanii, as well as the radiation-resistant bacterium Deinococcus radiodurans, were exposed to vacuum-UV (V-UV) radiation at the Br…
Microbial Fuel Cells Applied to the Metabolically-Based Detection of Extraterrestrial Life
Ximena C. Abrevaya, Pablo J. D. Mauas, Eduardo Cortón
Since the 1970's, when the Viking spacecrafts carried out experiments aimed to the detection of microbial metabolism on the surface of Mars, the search for nonspecific methods to d…
