The Hypothesis of a “Living Pulse” in Cells
Life, 2023 Motility is a great biosignature and its pattern is characteristic for specific microbes. However, motion does also occur within the cell by the myriads of ongoing processes within the cell and the exchange of gases and nutrients with the outside ...

Low Energy Subsurface Environments as Extraterrestrial Analogs [PDF]
Frontiers in Microbiology, 2018 Earth's subsurface is often isolated from phototrophic energy sources and characterized by chemotrophic modes of life. These environments are often oligotrophic and limited in electron donors or electron acceptors, and include continental crust, subseafloor oceanic crust, and marine sediment as well as subglacial lakes and the subsurface of polar ...

Modeling Virus and Bacteria Populations in Europa’s Subsurface Ocean
Life, 2022 The search for life in the universe is often informed by the study of “extreme” environments on Earth, which provide analogs for habitable locations in the Solar System, and whose microbial inhabitants may therefore also serve as analogs for potential ...

Nucleobase synthesis in interstellar ices
Nature Communications, 2019 The formation of nucleobases can take place in extraterrestrial environments. Here the authors show the simultaneous synthesis of three purine nucleobases and three pyrimidine from interstellar ice analogues that suggest the evolution from molecular ...
