Information processing constrains how E. coli bacteria navigate chemical gradients
Living organisms adapt their behavior and movements based on information they acquire from their surrounding environment. But oftentimes this information is imperfect, and the organism needs to act under uncertainty. So, ...
Life might be easiest to find on planets that match an earlier Earth
We're inching closer and closer to reliably detecting biosignatures on distant planets. Much of the focus is on determining which chemicals indicate life's presence.
