Biotechnological uses of enzymes from psychrophiles [PDF]

, 2011
The bulk of the Earth's biosphere is cold (e.g. 90% of the ocean's waters are ≤ 5°C), sustaining a broad diversity of microbial life. The permanently cold environments vary from the deep ocean to alpine reaches and to polar regions. Commensurate with the

Some Like It Hot –Structural Changes in Extremophile Rubredoxin at 120 °C

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We reveal the high temperature crystal structure of a hyperthermophilic (Pyrococcus furiosus) rubredoxin at 393 K (120 °C), together with multiple complementary structures down to 100 K. The results are compared with molecular dynamics calculations. Significant changes in H‐bonding are observed.

Subseafloor Temperature Variability During Ridge‐Flank Hydrothermal Circulation: Implications for a Moderate‐Temperature Earth System and Other Ocean Worlds

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Subseafloor hydrothermal circulation drives biogeochemical exchange between the solid Earth and its ocean, and could play a similar role in other ocean worlds. We assess the scale of subseafloor temperature (T) variations during hydrothermal circulation in ∼3.5 Ma seafloor on the eastern flank of Juan de Fuca Ridge. This well‐studied, moderate
