TL;DR: Time resolved experiments on PSII nano/microcrystals from Thermosynechococcus elongatus performed with the recently developed technique of serial femtosecond crystallography provide evidence that PSII undergoes significant conformational changes at the electron acceptor side and at the Mn4CaO5 core of the OEC.

TL;DR: This work demonstrates an ultrafast global conformational change that arises within picoseconds and precedes the propagation of heat through the protein, providing direct structural evidence for a 'protein quake'.

TL;DR: It is demonstrated that high-quality and damage-free protein structures can be obtained with the currently available 1.1 MHz repetition rate pulses using lysozyme as a test case and furthermore a β-lactamase structure.

TL;DR: In this paper, the authors studied the interactions of keV ions with isolated nucleobases and with nucleobase clusters by means of coincidence time-of-flight spectrometry.

TL;DR: For photon energies exceeding 10 eV a new dissociation scheme is identified in which photoabsorption leads to a fast loss of the tyrosine side chain, which leads to the formation of a residual peptide that is remarkably cold internally.
