US scientists achieve record fusion energy yield for second time, bringing carbon-free power source closer to reality

US scientists at Lawrence Livermore National Lab successfully conducted a second controlled fusion reaction experiment.
The latest experiment produced an even higher energy yield than the first breakthrough in December.
Powerful lasers were focused on a tiny hydrogen-filled target to create immense heat and pressure to fuse atoms.
While fusion power plants remain decades away, these milestones demonstrate fusion's potential as a clean energy source.
More research is still needed to scale up the technology and conduct further successful ignition events.
