This edition of CERN Courier explores one of the toughest challenges in applied superconductivity: high-field magnets for hadron colliders. In our cover feature, Ezio Todesco looks at the superconductors that could push back the energy frontier and the spinoff applications this work may inspire. Elsewhere, we examine a little-known tool behind countless papers, consider the mysterious little red dots discovered in the early universe, and meet Fermilab’s new director, Norbert Holtkamp.
