Negative refraction of light using atoms instead of metamaterials

Researchers at Lancaster University have successfully demonstrated negative refraction using atomic arrays, eliminating the need for metamaterials. This achievement paves the way for novel technologies based on negative refraction, including perfect lenses and cloaking devices.

Spider silk: Mother Nature's bio-superlens

Researchers at Bangor University have achieved a world first by using dragline silk from the golden web spider as an additional superlens to provide up to 2-3 times magnification. This innovation enables viewing of previously invisible structures, including nano-structures and biological micro-structures.
