U.S. researchers have designed a new computer algorithm that can model and catalogue the entire set of carbon-containing molecules, and created a map of the so-called ‘small-molecule universe’ (SMU). This map shows regions of the SMU that chemists have explored and the ones they haven’t (Virshup et. al.) The SMU is a set of all synthetically feasible organic molecules of 500 Daltons molecular weight or less. It has more than 10^60 chemical...
