We often like to think us humans have achieved a remarkable standard of efficiency and development – but a look at the animal life around us is often enough to humble us. Replicating bacteria and physics The common gut bacteria, Escherichia coli (E. coli, in short) typically takes about 20 minutes to duplicate itself in [...]
