Nickelates provide answers about high-temperature superconductivity—and raise new questions Shortly after researchers synthesized a family of superconducting nickelates in 2019, surprising discoveries were found in related yet distinct nickel compounds. Berit H. Goodge and Michael R. Norman Europe's particle-physics community weighs its next collider Looking to solidify their post-LHC plans, CERN and its partners are considering an ambitious project that would stretch to the end of the century. Matt von Hippel From the vault: October 1959 The history of the cyclotron On May 1, 1959, in memory of the late Ernest Orlando Lawrence, two invited lectures on the history of the cyclotron were presented as part of the American Physical Society's annual spring meeting in Washington, D.C. The present article is based on Prof. Livingston's talk on that occasion. M.
