Cosmic ray protons scattering off dark matter produce the Galactic Center gamma-ray excess through inelastic up-scattering followed by decay or direct elastic 2-to-3 photon production.

No signal found in first search for eta to pi0 plus invisible dark scalar decay, setting branching fraction limits of (1.8-5.5)x10^-5 at 90% CL and improving DM-nucleon cross section bounds by ~5 orders of magnitude.
XENONnT measures solar 8B neutrino coherent scattering at 3.3 sigma, finds no light dark matter, and constrains the weak mixing angle at low momentum transfer.
Boosted sub-GeV dark matter from atmospheric cosmic ray bremsstrahlung can be probed by direct detection and neutrino experiments, with enhanced sensitivity near vector mediator resonances.
Xenon data constrain inelastic fermion DM with scalar mediator for sub-MeV mass splittings through endothermic and exothermic DM-electron scattering.
An updated Thomas-Imel ionization model for liquid argon, constrained by ReD calibration data, produces new world-leading exclusion limits on 1-3 GeV/c² WIMPs.
Super-Kamiokande data constrains the DM-electron scattering cross-section for leptophilic dark matter to ~4e-41 cm2 below 100 GeV, exceeding direct detection by over an order of magnitude.
