UC San Diego researchers tracked nanoscale domain rearrangement in electrically operated vanadium-dioxide neuristors using operando coherent X-ray diffraction. Their findings show that current can change how the device learns and forgets a previous state.

The team examined the transition from a liquid-like mobile state to a jammed or glass-like state. According to the university, jamming the flow enables learning, while restoring free flow erases memory. This control offers an approach for research into brain-inspired computing hardware.

UC San Diego says the study appeared in Nature Communications on September 24, 2026; the university report followed on October 13. The result is a laboratory demonstration in materials physics, not an energy-consumption measurement or an already available commercial neuromorphic product.
