On page 1514, researchers report crushing microbes beneath the equivalent of a 160-kilometer column of water--and showing that some of them can actually survive. To some microbiologists this suggests that similar organisms might survive the high-pressure environments of other celestial bodies, like Jupiter9s moon Europa. 

The search for life on Europa: limiting environmental factors, potential habitats, and Earth analogues.

Model simulations demonstrate that hypothetical oceans could exist on Europa that are too cold for biological activity (T < 253 K), and demonstrate that salinities are high, which would restrict life to extreme halophiles.

Astrobiology and the Search for Life in the Universe

The requirements for life as the authors know it are examined, with constraints for life, biosignatures, and geosignatures as guidelines, and a strategy to search for life in the universe is elaborated on.

Microscopy under pressure—An optical chamber system for fluorescence microscopic analysis of living cells under high hydrostatic pressure

An optical pressure chamber that can be used for up to 300 MPa and stained with the fluorescent dyes propidium iodide, Hoechst 33342, or dihexyloxacarbocyanine iodide was constructed and it was shown that the system is suitable to perform fluorescence microscopic analyses, with pressures up to300 MPa, with viable mammalian cells.
