Whether at a family gathering or in a research lab, getting access to images immediately was a game-changer. And Land’s innovations went far beyond the instant photo.
While some things glow all the time, glow-in-the-dark paint must be ‘told to glow’ - just like a phone needs to be charged or it won’t work.

You can see glow-in-the dark paint, but if you touch it, it is just as cold as the bedroom wall. So the glowing of the paint is different to the glowing of a light bulb.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
Super-black feathers on these guys are like looking into a dark cave.

Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers’ microscopic structures that make them look so very dark.
Diatoms - like those seen under a microscope here - can teach us a lot about harvesting light.

Diatoms’ tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
Example of nonlinear effect which can be observed in an optical fiber. All the colors of the rainbow are generated at the output while only one color is present at the entrance. We’re talking about supercontinuum.
To understand what is happening in an optical fibre, physicists can mimic a rupture of the flow of grains of light – the photons – thanks to a laser device.
Bathing in pure colour can have effects on the body and mind.
Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.

We’re used to thinking of our eyes detecting light as the foundation of our visual system. But what’s going on in other cells throughout the body that can detect light, too?
Earth, shot from space, as it absorbs and reflects rays of light coming from the Sun - the same white-looking rays that give our sky its colour.

Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
Time to get up.

Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.
The wrong kind of light can seriously impact your well-being.
Light from the universe’s first galaxies destroyed the hydrogen atoms that formed during the Big Bang.

Freezing light in mid-air isn’t just the realm of Star Wars, as new research shows. But what do you do with the light once it’s trapped? One option is to use it to develop new forms of computers.
Flexible light-emitting screens mean you soon won’t need bulbs because your wallpaper – or even your furniture – will light up at the flick of a switch.
