Scientists at the University of Cambridge developed a new method to manufacture invisible "metamaterials" using lasers, leading to the possibility of invisibility cloaks.
Using an unfocussed laser light to stitch particles of gold together, the researchers created a material that reflected light through inverse refraction, making objects covered by it appear invisible.
Like a lot of technology in this field, the cloaking device is most likely to find its first applications in the military.
