A new generation of retinal implants could use light to provide power and data, potentially restoring vision in a less-invasive form than existing implants. Researchers at Stanford University previously described how such a system would work, and now they’ve designed implants that can receive infrared signals for power and information processing.
Glow-in-the-dark devices, which emit visible light after exposure to sunlight, are as commonplace as a wristwatch. But these are not that great when you want to see and not be seen — say you're a special ops soldier checking the time while tracking an enemy. In that situation, a glow-in-the-night-vision device would be far more effective. Now scientists at the University of Georgia have invented just such a device — a new material that emits a long-lasting infrared glow after a single minute of exposure to light.
Hovering landers or drones look as though they’re suspended in the air, because you can’t see the vortices caused by the propellers or the heat emitted by the thruster, or whatever mechanism enables the hovering. Well, here you can. And it proves that the act of hovering is anything but delicate.
Finally: a flash camera without all the usual problems. By using a flashbulb that emits ultraviolet and infrared light (neither of which the human eye can detect) instead of visible light, New York University's Dilip Krishnan and Rob Fergus have come up with dark photography that will neither blind your subject nor produce the unwanted glare of a harsh flash in the developed photo.
An electronic circuit 100 times smaller than a hair, could help astronomers shed light on the universe's creation

For centuries, the creation of the universe has loomed large in human thought, cropping up in everything from ancient folklore to modern scientific theories. A newly-developed nano-sized device, 100 times smaller than the thickness of human hair and capable of detecting infrared light that dates back to the "big bang," could soon give us more food for thought concerning the galaxy's formation 14 billion years ago.
