How to thermally cloak an object

Theoretical method can make objects invisible to a thermal camera, or mimic a different object

Using sound waves to make patterns that never repeat

Collaboration between mathematicians and engineers could lead to customizable materials.

Thin to win

U engineers develop a thin, lightweight lens that could produce slimmer camera phones, longer-flying drones and thermal imaging cameras, such as for finding victims of natural disasters.
