A southward-looking panorama combining images from both cameras of the Mast Camera (Mastcam) instrument on NASA’s Curiosity Mars Rover shows diverse geological textures on Mount Sharp. This work examines the

Experimental schematic of metagenomic libraries and screening. — Scientific Reports As we assess the habitability of other worlds, we are limited by being able to only study terrestrial life adapted

A small planet orbiting its host star – Grok via Astrobiology.com Future telescopes will survey temperate, terrestrial exoplanets to estimate the frequency of habitable (ηHab) or inhabited (ηLife) planets. This

An integrated approach to date bacterial evolution and reconstruct the history of oxygen adaptation. We inferred a bacterial timetree by integrating genomic, fossil, and geochemical data and linking oxygen tolerance
