The 2018 Nobel Prize in Chemistry has been awarded to three scientists for their discoveries in enzyme research.
Americans Frances Arnold and George P Smith will share the prize with Briton Gregory Winter, who is based at Cambridge University.
This year’s winners used a technique called directed evolution to create new enzymes – which accelerate chemical reactions in biology.
The award is worth nine million Swedish kronor (£770,686; $998,618).
