New Applications of High-Resolution Analytical Methods to Study Trace Organic Compounds in Extraterrestrial Materials [PDF]
Organic compounds are present as complex mixtures in extraterrestrial materials including meteorites, which may have played important roles in the origin of life on the primitive Earth.

Simulating microbial processes in extraterrestrial, aqueous environments [PDF]
Finding evidence of life elsewhere in the Solar System is dependent on understanding biotic processes that could occur within potentially habitable environments. Here, we describe a suite of high-pressure flow-through reactors that have been developed to investigate biotic and abiotic processes within simulated sub-surface martian and icy moon ...

An overview of experimental simulations of microbial activity in early Earth
Microbial activity has shaped the evolution of the ocean and atmosphere throughout the Earth history. Thus, experimental simulations of microbial metabolism under the environment conditions of the early Earth can provide vital information regarding ...

Coordinated polar spacecraft, geosynchronous spacecraft, and ground-based observations of magnetopause processes and their coupling to the ionosphere [PDF]
In this paper, we present in-situ observations of processes occurring at the magnetopause and vicinity, including surface waves, oscillatory magnetospheric field lines, and flux transfer events, and coordinated observations at geosynchronous orbit by ...

The Adaptability of Life on Earth and the Diversity of Planetary Habitats
The evolutionary adaptability of life to extreme environments is astounding given that all life on Earth is based on the same fundamental biochemistry. The range of some physicochemical parameters on Earth exceeds the ability of life to adapt, but stays ...

Lezioni dall’Antartide. Per un’ecologia del sistema solare [PDF]
Lessons from Antarctica. For an ecology of the Solar System It seems plausible that the near future will see an ever greater expansion of human presence in several environments of the Solar System, such as the Moon and the planet Mars.

The Hypothesis of a “Living Pulse” in Cells
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]
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
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 ...
