Nanotechnology makes it possible for mice to see in infrared

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice's eyes bestowed ...

Chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.

Creating displays with richer colours

National University of Singapore researchers have developed a colour-enhancement film that could bring richer and more natural colours to next-generation flat-panel electronic displays.

Curing blindness with stem cells – here's the latest science

In 2006, Nature published a paper describing how stem cells could be used to restore sight in blind mice. This study, and similar subsequent studies, created a lot of excitement about the potential of stem cells to cure blindness ...

Two studies find stress reprograms cells

In a pair of publications, researchers have shown how cells adapt to stressors—like water loss—by reprogramming their internal signaling networks. The studies describe previously unknown mechanisms that cells use to send ...
