    The existence, nature and biological relevance of mechanoradicals in proteins are unknown. Here authors show that mechanical stress on collagen produces radicals and subsequently reactive oxygen species and suggest that collagen I evolved as a radical sponge against mechano-oxidative damage.

    Organic-inorganic hybrid halide perovskites have been emerged as promising candidates for X-ray detectors while toxicity and instability are known issues. Here, Zhang et al. grow large size lead-free single crystals for high performance X-ray detection and imaging devices that can operate at 100 °C.
