Team produces weird optical phenomena - and rewrites the rules of refraction

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have induced light rays to behave in a way that defies the laws of reflection and refraction, while producing some weird fun-house images on the way.

Distracted driving laws in disarray, says researcher

The current lack of consensus about distracted driving in the US has one advantage, say scientists at Temple University - it means it'll be easier to work out which laws make sense and which don't.
