The idea that complex biological systems can evolve through a series of simple, random events is not universally accepted. The structure of a vital immune protein shows how such evolution can occur at a molecular level

How much and what kind of information is required to fold a chain of amino acids into a functioning protein? It seems the problem may not be as daunting as once thought — the solution is in the coevolution data

Magnetic resonance imaging is often limited by the need to encode information and acquire the resonance signals in less-than-ideal locations. Performing these two steps at different places provides a solution
