Although we have a reasonable understanding of the physical and chemical conditions
required to support the growth and reproduction of organisms, we still have only a …

The physical processes active during the first billion years (FBY) of Earth's history, such as
accretion, differentiation, and impact cratering, provide constraints on the initial conditions …

This opinion paper describes the potential (yet underutilized) use of a transcriptomic tool,
RNA-seq, to study the cellular responses and adaptations of halophilic microbes to extreme …

We describe the recent progress and development of a compressed CO 2 hard rock drill for
Mars that is intended to facilitate the extraction and retrieval of deep, subsurface samples. A …

Recent analysis of data from the Cassini Cosmic Dust Analyzer confirm geochemical
modeling work that shows that the ocean of Enceladus contains considerable quantities of …

Concretions are mineral masses that form in response to changes in chemical conditions,
porosity/permeability conditions, and pore-fluid composition during diagenesis. Large (up …

Extreme conditions in wetlands may be the niche of development of colonies of bacteria. In
this chapter, the authors study the gnotobiology of moderate bacteria within the saline …

This study sheds light on geomorphological phenomena that spread on the surface of
Earth's twin planet (Mars), and we believe that it will fill a void in what has been published …
