PANCAKES have been getting in the way of nuclear fusion: the process comes unstuck when fuel pellets end up spread out flat. Now the world’s largest laser complex has solved the problem. Fusion should start if a laser pulse heats a fuel pellet and squeezes it very tight. But if the nuclear fuel spreads out from the implosion zone, input energy is lost. Using the huge laser power of the US National Ignition Facility,
