This week’s Alchemist

This week, The Alchemist takes another look at an old friend, aspirin, that most venerable of pharmaceuticals. He also sheds light on catalysts and a silicon version of the carbon allotrope graphene. In the physical arena, splitting the electron is on the cards and a DNA triple helix comes to the fore in biology. Finally, an international award for a Chinese chemist.
