Crystal Mn3Si2Te6, exposed to a magnetic field and a weak current, pushes back like a spring refusing to let the current change. Inside, microscopic whirlpools of electron flow rearrange in sync. This could miniaturize components for quantum electronics without tricky fabrication.

Noise in quantum computers unexpectedly accelerates the preparation of thermal states. Like shaking a glass of sugar, it forces the system to reach complete chaos faster. The discovery allows imperfect quantum machines to be used for practical tasks today.

Physicists are hunting axions—light particles that might make up dark matter. They built a device with a levitating magnetized rod that should tremble if axions fly through it. In a new experiment, the rod stayed still, but the scientists set record constraints on how strongly axions interact with o
