The vast neutrino telescope KM3NeT is taking shape deep beneath the Mediterranean Sea. Combined with recent evidence of high-energy neutrino emission from a nearby galaxy reported by the IceCube collaboration and the growth of the Baikal-GVD detector, neutrino astronomy is entering its golden era.

As LHC Run 3 gets into its stride, the November/December issue also reports on the completion of civil engineering for the High-Luminosity LHC and takes an in-depth look at the crystal collimation essential for high-luminosity operations. Going beyond the LHC: how to deal with the millions of cubic metres of excavation materials from the proposed Future Circular Collider (FCC) at CERN, and a new project to explore the use of high-temperature superconductors for FCC-ee. Post-LHC colliders also feature large in the recently completed Snowmass community planning exercise.

Elsewhere in the issue: newly founded firm TAU Systems aims to commercialise plasma-wakefield accelerators; a new international society for quantum gravity; IPPOG turns 25; Swiss Physical Society evaluates the impact of physics; plus the latest conference reports, LHC-experiment results, reviews, opinion and more!
