A new model shows that the nonuniform heating of ions in the solar wind may be explained by resonant interactions with a particular type of plasma wave.

Lasers produce a beam of neutrons intense enough for practical experiments, extending the reach of neutron sources to small-scale laboratories.

Relativistic electrons passing through a laser-produced plasma map out magnetic fields that move at nearly the speed of light.

Simulations show that controlled beating of multiple laser frequencies optimizes energy delivery to inertial fusion targets.

Focusing a beam of light on a slit reveals details of its polarization with surprising sensitivity.
