Caffeine fix: how physics can improve your coffee

Coffee has been shooting up in price due to climate change, which has been disrupting production and lowering yields.

Discover more about the physics of coffee in Michael Allen’s cover feature. Also this month, find out why patents are so valuable in quantum technology, explore what happened at the Global Physics Summit, and relive the Artemis II mission to the Moon. Don’t miss either an interview with new IOP president Paul Howarth.
