Study Illustrates Metasurface-Driven Optically Variable Devices for Anti-Counterfeiting

The increasing risk of advanced counterfeits always poses a need for a security device that can combat them. A technology never known before can be utilized in security devices. However, it is hard to make a comparison of their strengths as no standards were available to quantify their performance.

Synchronisation is More Readily Achieved in Many Systems than Previously Thought

Physicists from Trinity College Dublin have unlocked the secret that explains how large groups of individual "oscillators" – from flashing fireflies to cheering crowds, and from ticking clocks to clicking metronomes – tend to synchronise when in each other's company.
