High in the forests of Hawai‘i, songbirds are stealing twigs and moss from one another’s nests. UC Riverside researchers found this quiet canopy crime is surprisingly common and could threaten species already struggling to survive.

A fluoride-assisted strategy improves perovskite nanocrystals embedded in glass, enabling stable, high-efficiency full-spectrum emission, including record blue performance. The material supports tunable RGB output under a single excitation source. Integrated with holographic techniques and spatial light modulation, it achieves ultra-high pixel density (~20,000 PPI). A vertically stacked RGB design further enhances light utilization and resolution, offering a promising route toward energy-efficient, next-generation multicolor display technologies.
