Stackable 'holobricks' can make giant 3D images

Researchers have developed a new method to display highly realistic holographic images using 'holobricks' that can be stacked together to generate large-scale holograms.

Distortion-free, stretchable micro-LED meta-display technology

The Korea Institute of Machinery and Materials (KIMM) has successfully developed the first stretchable meta-display technology that can be stretched up to 25% without image distortion. The results are published in Advanced ...

New model links mate selection to species survival

In a new paper published in Ecology Letters, Michigan State University evolutionary biologist Janette Boughman shows that the process of choosing a mate could be very important to the survival of the species. To do this, ...

Blue LEDs light the way toward sustainable development

Light-emitting diodes (LEDs) are commonly used in the electronic displays in our TVs, smartphones, and other devices; now, researchers at the Institute of Chemical Reaction Design and Discovery (ICReDD) at Hokkaido University ...

Controlling light with a material three atoms thick

Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close—or open—our window blinds.

Reconfigurable metasurfaces provide nanoscale light control

Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve ...
