Sneezing from cats, dust mites, or mold may one day be preventable with a flip of a switch. Researchers at CU Boulder found that UV222 light can alter allergen proteins, reducing allergic reactions without dangerous side effects. Within 30 minutes, airborne allergens decreased by up to 25%. The team imagines portable devices that could shield people in homes, schools, and workplaces from harmful triggers.

Scientists have developed a new multi-layered metalens design that could revolutionize portable optics in devices like phones, drones, and satellites. By stacking metamaterial layers instead of relying on a single one, the team overcame fundamental limits in focusing multiple wavelengths of light. Their algorithm-driven approach produced intricate nanostructures shaped like clovers, propellers, and squares, enabling improved performance, scalability, and polarization independence.
