A new way to fine-tune exotic materials: Thin, stretch and clamp
Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad range of materials for use in things like sensors and detectors.

An advance in molecular moviemaking reveals the subtle, complex ways a simple molecule can shimmy and fly apart
Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into molecular behavior.

Scientists finally find superconductivity in exactly the place they've been looking for decades
The Hubbard model, used to understand electron behavior in numerous quantum materials, now shows us its stripes, and superconductivity too, in simulations for cuprate superconductors.
