A section of Life (ISSN 2075-1729).
Papers published in this section fall within the field of astrobiology, defined as the study of the origin, evolution, distribution and future of life in the universe. While prebiotic and organic chemistry of early life is covered in the chemistry section of the Journal, one of the focal points of this section is the emergence, coordination and evolution of functions, structures and processes characteristic of life. Both experimental and theoretical studies addressing different functions of early cells, such as metabolism, inheritance, regulation, bioenergetics, signal transduction and transport acting separately or in concert are welcomed. Another emphasis of this section is on life detection. This covers a number of topics. What are signs of life? What environmental conditions can support life? How can signs of life be recognized and evaluated in missions and observations? Well-researched rather than highly speculative manuscripts on these and related topics are of interest. Other high-quality manuscripts that contribute to astrobiology are also invited.
