Understanding behavioral patterns: Why bird flocks move in unison
Animal flocks, be it honeybees, fish, ants or birds, often move in surprising synchronicity and seemingly make unanimous decisions at a moment's notice, a phenomenon which has remained puzzling to many researchers.

Nick of time: Temporal variation of light-matter interaction boosts photonic metamaterials
At the interface between two media, light is partly reflected backwards into the medium from where it came and partly transmitted into the neighboring medium, like a light ray entering a sparkling pool of water. The light ...

Stimulating resonance with two very different forces
Widely studied in many different fields, 'nonlinear' systems can display excessively dramatic responses when the forces which cause them to vibrate are changed. Some of these systems are sensitive to changes in the very parameters ...
