This graphic takes a look at how alcohol-free beer is defined, the range of ways in which it can be made, and how these methods work.
Though there are hundreds of different types of cheese, their manufacture follows some common steps. In the latest edition of Periodic Graphics in Chemical & Engineering News, we take a look at the biochemical processes that turn milk into cheese. View the full graphic on the C&EN site.
Dandelions: Loved by children, loathed by (most) gardeners. Often dismissed as a weed, dandelions lend themselves to several uses — and might be the solution to making more sustainable car tyres.
