Two scientists have been awarded the 2021 Nobel Prize in Chemistry for their work on building molecules that are mirror images of one another.
German-born Benjamin List and Scotland-born David MacMillan were announced as the winners at an event in Stockholm.
Their chemical toolkit has been used for discovering new drugs and making molecules that can capture light in solar cells.
The winners will share the prize money of 10 million krona (£842,611).
