  • Here, the authors report parametric down-conversion of X-rays into long wavelength radiation in gallium arsenide and lithium niobate crystals, with efficiencies about 4 orders of magnitude stronger than the efficiencies measured in any material studied previously. They explore the lack of inversion symmetry as a possible physical mechanism.

  • Mutations in human PIEZO2, encoding for a mechanosensitive ion channel, lead to skeletal abnormalities including scoliosis and hip dysplasia. Here, the authors show that deletion of Piezo2 in proprioceptive neurons, but not in skeletal lineages, recapitulated the human phenotype in mice.

  • Radiation–matter interactions can become highly nonlinear when using high-intensity X-ray free-electron lasers. Under such conditions, it is shown that nonlinear Compton scattering has an anomalous redshift, whose origin remains unclear.

  • X-ray computed tomography is a widely used technique for non-invasively visualizing the interior of the human body. A. Ben Yahuda and colleagues report a technique for incorporating scattered radiation data in Computed Tomography scans to improve image resolution and minimize radiation exposure for patients.
