Your genetic code has lots of 'words' for the same thing – information theory may help explain the redundancies

Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.

Water was both essential and a barrier to early life on Earth – microdroplets are one potential solution to this paradox

The chemical reaction that forms essential biomolecules like proteins and DNA normally doesn’t occur in the presence of water. Microdroplets provide a unique environment that make it possible.

Many drugs have mirror image chemical structures – while one may be helpful, the other may be harmful

From thalidomide to resveratrol, molecules with the exact same chemical properties can have drastically different effects in the body depending on how they’re arranged in space.
