Bacteria Show Capacity for Rapid, Beneficial Mutations

AUSTIN, Texas — Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in adapting to its environment. In a new … Continue reading

Engineering Bacterial Live Wires

Berkeley Lab scientists discover the balance that allows electricity to flow between cells and electronics Just like electronics, living cells use electrons for energy and information transfer. Despite electrons being a common “language” of the living and electronic worlds, living … Continue reading

Mutant Champions Save Imperiled Species from Almost-Certain Extinction

Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make … Continue reading
