    Unusual radiation damages effect resulting in the collapse of the crystals. Dramatic images, highly publicised. Important consequences for the existence of crystals.
During coherent X-ray diffraction measurements on crystals of ferritin at room temperature using monochromatic undulator radiation from the Advanced Photon Source, a sudden lattice contraction was observed following a characteristic latent period and ultimately leading to the collapse of the crystal. The progression of this collapse is analysed using a two-state Hendricks–Teller model. It reveals that 55% of the layers collapse by 1.6% before the crystal completely stops diffracting.
