Movable silicon 'lenses' enable neutrons to see new range of details inside objects

You can't see well without lenses that can focus, whether those lenses are in your eye or the microscope you peer through. An innovative new way to focus beams of neutrons might allow scientists to probe the interiors of opaque objects at a size range they were blind to previously, allowing them to explore the innards of objects from meteorites to cutting-edge manufactured materials without damaging them.
