New experiments suggest that freezing and thawing on early Earth may have helped primitive cell-like structures grow and evolve. Tiny lipid bubbles behaved very differently depending on their membrane makeup—some fused into larger compartments and…
Scientists have discovered that methane in the open ocean is produced by microbes under nutrient-poor conditions, solving a long-standing mystery. As warming oceans reduce nutrient mixing, these methane-producing microbes may thrive.…
