Single-atom-resolved fluorescence imaging of an atomic Mott insulator
For several years, researchers have aspired to record in situ images of a quantum fluid in which each underlying quantum particle is detected. This goal has now been achieved: here, fluorescence imaging is reported of strongly interacting bosonic Mott insulators in an optical lattice, with single-atom and single-site resolution. The approach opens up new avenues for the manipulation, analysis and applications of strongly interacting quantum gases on a lattice.

Structural basis for the photoconversion of a phytochrome to the activated Pfr form
Phytochromes regulate numerous photoresponses in plants and microorganisms through their ability to photointerconvert between a red-light-absorbing, ground state (Pf) and a far-red-light-absorbing, photoactivated state (Pfr). The structures of several phytochromes as Pf have been determined previously; here, the three-dimensional solution structure of the bilin-binding domain as Pfr is described. The results shed light on the structural basis for photoconversion to the activated Pfr form.
