The many faces of a proton
A joint X-ray/neutron diffraction study has enabled the direct observation of a hydronium ion coordinated by three amino-acid residues of an enzyme. This sighting will affect our views on how enzymes transport and use protons.

Anion transport as easy as pi
A systematic study that combines both theory and experiment now provides direct evidence for the existence of anion–π interactions in compounds that facilitate the transport of anions across phospholipid membranes. This study offers new insight into the factors that affect the strength, selectivity and functional relevance of anion–π interactions.
