Hidden State Precedes Superconductivity in Kagome Metal

Experiments at the ALS revealed a hidden electronic phase that breaks time-reversal symmetry before a charge-density wave forms in a kagome metal. Because hidden electronic order can compete with or shape superconductivity, this finding helps guide the search for high-temperature, unconventional superconducting materials. Read more »

Scientists Uncover How Calcite Repairs Cracks in Its Structure

Researchers uncovered how calcite repairs cracks in its structure over time. These findings could improve reservoir management for extracting resources such as geothermal energy from the Earth. Read more »

Microscopy Reveals How Early Human Diets Led to Tougher Teeth

Microscopy at the ALS revealed that nanocrystal misorientation in tooth enamel tracked major dietary shifts in primates, contributing to enamel’s resilience. These structural details provide a blueprint for developing tougher, crack-resistant bioinspired materials, next-generation structural ceramics, and coatings. Read more »
