In December 2022, after more than a decade of effort and frustration, scientists at the US National Ignition Facility (NIF) announced that they had set a world record by produc-inga nuclear-fusion reaction that released more energy than it consumed - a phenomenon known as ignition. They have now proved that the feat was no accident by replicating it again and again, and the administration of US President Joe Biden is looking to build on this success by establishing a trio of US research centres to help advance the science. The stadium-sized laser facility, housed at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California, has unequivocally achieved its goal of ignition in four out of its past six attempts, creating a reaction that generates pressures and temperaturesgreater than those that occur inside the Sun. "I'm feeling pretty good," says Richard Town, a physicist who heads the inertial-confinement fusion science programme at the LLNL. "I think we should all be proud of the achievement."
