Dear Reader, The biggest event of this week—or maybe even of this year, if you're a physicist—is the long-awaited restart of the Large Hadron Collider (LHC), the world's most powerful particle accelerator, which has been shut down since late 2018 to receive repairs and enhancements. Our top story delves deep into the arduous work behind some of the LHC's biggest new upgrades, detailing not only how they were achieved but also the sorts of new physics they may ultimately reveal. Elsewhere, we have articles about the ongoing decay of Russia's international space partnerships, new approaches to quantum-error correction, and the latest chapters in the historic saga of a "lost woman of science," Klára Dán von Neumann. Enjoy!

QUOTE OF THE DAY "The accelerator has been off for three years. So there's people who have never been in the control room, [who] never have done shifts where data was taken. And for them, it's extremely exciting." Freya Blekman, experimental particle physicist working on CERN's Large Hadron Collider
