  • Human RIF1 protein protects cells from DNA replication stress, through mechanisms that remain uncertain. Here the authors demonstrate that the RIF1-Long isoform interacts with BRCA1 upon extended replication stress, enabling RAD51-dependent repair of broken replication forks.

  • X-ray observations of the core of the Perseus cluster reveal a remarkably quiescent atmosphere in which the gas has a line-of-sight velocity dispersion of about 164 kilometres per second in the region 30–60 kiloparsecs from the central nucleus; turbulent pressure support in the gas is four per cent of the thermodynamic pressure, necessitating only a small correction to the total cluster mass determined from hydrostatic equilibrium.

  • High-resolution X-ray spectra show near-solar abundances of chromium, manganese and nickel with respect to iron in the Perseus cluster, suggesting that the progenitors of type Ia supernovae could be near- and sub-Chandrasekhar-mass white dwarfs.
