The M.Zuiko 17mm F1.8 II doesn't quite make that grade but falls into a category of small primes that I like to describe as a ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...
