  • The internal structure of the neutron has now been probed by highly energetic photons scattering off it. Combined with previous results for protons, these measurements reveal the contributions of quark flavours to the nucleon structure.

  • It remains a challenge to find the structure and the distribution of the constituents of nucleons. Here the authors use a scattering method to get information about the gluons and quarks inside a proton and separate the contribution of Bethe-Heitler from the deeply virtual Compton scattering process.

  • A high-precision parity-violating electron–quark scattering experiment provides measurements of a combination of electron–quark weak couplings with a precision five times higher than the single previous direct study, confirming the predictions of the electroweak particle-physics theory and providing constraints on parity-violating interactions beyond the standard model.
