• CERN scientists announced the discovery of the Ξcc⁺ particle, a long-predicted heavy cousin of the proton, resolving a 20-year mystery in particle physics. • The breakthrough marks the first particle discovery with the upgraded LHCb detector, involving over 1,000 researchers from 20 countries, with the UK contributing the most led by University of Manchester's Professor Chris Parkes. • Professor Parkes stated, 'Rutherford's gold-foil experiment in a Manchester basement transformed our understanding of matter, and today's discovery builds on that legacy.'
