Desulfuromonas acetexigens on a metal electrod surface. Credits: KAUST. Microbes are masters of survival, evolving ingenious strategies to capture energy from their surroundings. For decades, scientists believed that only a

Evolution of nominal-composition cases across the full range of fO2 and tidal power densities simulated (see Section 2.3). Panel A (left): stages in planet’s lifetime after model initialization. Dotted lines

Dissimilarity analysis of evenness curves of amino acid assemblages. (a): Multidimensional Scaling (MDS) projection of dissimilarities between evenness curves, E(q). Points represent samples; distances between samples grow with dissimilarity. Edges

Hektoria Glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated. This video illustrates how and why

Blue serpentinite mud from a newly discovered mud volcano in a gravity core. The samples have been studied by a team in order to decipher the survival strategies of microorganisms.

The temperature versus depth and time for 𝜅 = 10−4 W m−1 K−1 , 10−3 W m−1 K−1, and 10−2 W m−1 K−1 (top, middle, and bottom panels). The sublimation

Schematic illustration of interstellar comet 3I/ATLAS showing the expected stratigraphy of an irradiated nucleus. Galactic cosmic ray irradiation over several Gyr alters the outer ∼15–20 m, producing a CO2-rich crust
