New tractor beam technology could one day minimize biopsy trauma

Researchers at TMOS, the ARC Center of Excellence for Transformative Meta-Optical Systems, have taken an important first step in the development of metasurface-enabled tractor beams—rays of light that can pull particles ...

Can a computer chip have zero energy loss in 1.58 dimensions?

What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and ...
