Endospores of Bacillus spp., especially Bacillus subtilis, have served as experimental
models for exploring the molecular mechanisms underlying the incredible longevity of …

The responses of microorganisms (viruses, bacterial cells, bacterial and fungal spores, and
lichens) to selected factors of space (microgravity, galactic cosmic radiation, solar UV …

Alien Ocean immerses readers in worlds being newly explored by marine biologists, worlds
usually out of sight and reach: the deep sea, the microscopic realm, and oceans beyond …

Two major types of environment provide habitats for the most xerophilic organisms known:
foods preserved by some form of dehydration or enhanced sugar levels, and hypersaline …

A radiative transfer model is used to quantitatively investigate aspects of the martian
ultraviolet radiation environment, past and present. Biological action spectra for DNA …

This experiment was aimed at establishing, for the first time, the survival capability of lichens
exposed to space conditions. In particular, the damaging effect of various wavelengths of …

We report that the halophilic archaeon Halobacterium sp. strain NRC-1 is highly resistant to
desiccation, high vacuum and 60 Co gamma irradiation. Halobacterium sp. was able to …

In view of the finding of perchlorate among the salts detected by the Phoenix Lander on
Mars, we investigated the relationships of halophilic heterotrophic microorganisms (archaea …

Salts are abundant on Mars, and any liquid water that is present or may have been present
on the planet is expected to be hypersaline. Halophilic archaea (family Halobacteriaceae) …

One of the biggest challenges of science is the determination of whether extraterrestrial life
exists. Although potential habitable areas might be available for complex life, it is more likely …
