Planet Earth has evolved over the past 4.5 billion years from an entirely anoxic planet with
possibly a different tectonic regime to the oxygenated world with horizontal plate tectonics …

Chemically oscillating reactions (COR) are abiotic processes that generate self-repeating
circularly concentric morphologies during decarboxylation of organic acids. The geometry …

Of all the planets in our solar system, Mars is most likely to have evidence of life, whether
past or extant and preserve the environments in which such life may have formed and lived …

Host to some of Earth's earliest evidence of life, the fossiliferous lowermost chert-barite

Of the planets in our solar system, Mars may be the most likely place to find evidence of life
and learn about planetary evolution. However, in exploring Mars, we risk damaging sites of …

The surface of Mars is universally thought to have experienced widespread cold and dry
environmental conditions for at least the last half of its geologic history, with more modern …

Fossil organic matter (OM) in Paleoarchean rocks is an invaluable tracer of ancient life, yet it
is often contentious due to low preservation potentials of its original organic molecular …

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 …
