What's up in
Superconductivity has been discovered in graphene devices without any twists, suggesting the form of superconductivity in the material might be mundane after all.
In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted.
Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.
At the molecular level, glass looks like a liquid. But an artificial neural network has picked up on hidden structure in its molecules that may explain why glass is rigid like a solid.
One hundred years after it was proposed, the Ising model is used to understand everything from magnets to brains.
