Researchers have developed a new "camera" that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.

Researchers joined two different materials to enable skyrmion generation.
