AbstractLife on Earth relies on mechanisms to store heritable information and translate this information into cellular machinery required for biological activity. In all known life, storage, regulation, and translation are provided by DNA, RNA, and ribosomes.

The 56 Fe/ 54 Fe of Fe-bearing phases precipitated in sedimentary environments varies by 2.5 per mil (δ 56 Fe values of +0.9 to −1.6 per mil). In contrast, the 56 Fe/ 54 Fe of Fe-bearing phases in igneous rocks from Earth

Life, as we know it, is based on carbon chemistry operating in an aqueous environment. Living organisms process chemicals, make copies of themselves, are autonomous and evolve in concert with the environment. All these characteristics are driven by, and operate through, carbon chemistry.

The interplay between Geology and Biology has shaped the Earth from the early Precambrian, 4 billion years ago. Moving beyond the borders of the classical core disciplines, Geobiology strives to identify cause-and-effect chains and synergisms between the geo- and the biospheres that have been driving evolution of life in modern and ancient environments.

The term health is commonplace in both everyday parlance and professional discourse. Unfortunately, the term has little objective specification, especially in physiologic terms. When critically examined, even time-honored terms such as homeostasis lack specific measurable referents.

A major goal of NASA's Origins Program is to find habitable planets around other stars and determine which might harbor life. Determining whether or not an extrasolar planet harbors life requires an understanding of what spectral features (i.e., biosignatures) might result from life's presence.

In this chapter, mhealth solutions for remote monitoring of ex vivo biosignatures is initially discussed in lieu of instrumentation. A summary of versatile sensor technologies that incorporate numerous features and the recommended methods for the critical steps of data acquisition in real-world settings is presented.

As technology advances, we have more possibilities to search for past life, looking for biosignatures in the rock record. Even when these biosignatures can be chemical compounds, the irrevocable evidence of past life would be life itself preserved as fossils.
