This could have been posted in the "breaking news" forum, but I'm not sure it quite fits there, so I put it here. Feel free to move.

Scientists have rendered objects invisible under near-infrared light.

Unlike previous such "cloaks", the new work does not employ metals, which introduce losses of light and result in imperfect cloaking.

Because the approach can be scaled down further in size, researchers say this is a major step towards a cloak that would work for visible light.
