In this episode of the Physics World Weekly podcast, Matin Durrani reports from CERN where he learns all about the ongoing major upgrade to the large hadron collider (LHC). Researchers and engineers explain what the High-Luminosity LHC – due to switch on in 2021 – will mean for the various experiments, including ATLAS, CMS and LHCb.

Also in the programme, we’ll also bring you some of the news highlights from our website this week ­­­– including how machine-learning can help diagnose cancer and the first-ever seismic signal to be measured on Mars. If you enjoy what you hear, then you can subscribe to Physics World Weekly via Apple podcasts or your chosen podcast host. As promised in the podcast, here is a link to physicist Lincoln Carr’s appearance on this podcast last year, where he speaks about why scientists should have a good grounding in the humanities.
