  • Bacteriorhodopsin (bR) is a light-driven proton pump. Here the authors combine time-resolved crystallography at a free-electron laser, ultrafast spectroscopy and quantum chemistry to study the structural changes following multiphoton photoexcitation of bR and find that they occur within 300 fs not only in the light-absorbing chromophore but also in the surrounding protein.

  • An environmentally safe means of mosquito control is the application of Bacillus thuringiensis israelensis, which produces a cocktail of four naturally crystalline proteins exclusively toxic to mosquito. Here the authors report the atomic-resolution structures of Bti Cry11Aa and related Btj Cry11Ba solved de novo through Serial Femtosecond Crystallography on naturally-occurring nanocrystals.
