Aiming at a target: the science of particle production

For some, a target is part of a game of darts. For others, it's a retail chain. In particle physics, it's the site of an intense, complex environment that plays a crucial role in generating the universe's smallest components ...

Cell membranes: Synthetics save time and cut costs

Screening for critical drug targets known as G-protein-coupled receptors (GPCRs) is now possible without the need to extract these proteins from their native cells. Extraction requires the use of stabilizing lipids, which ...
