Turning off a light just became a much smaller task. A team of researchers has developed the world’s smallest optical switch, which uses just a single atom to control the flow of light.
The good minds at MIT have used a rubber-like polymer to predict how much light gets transmitted through a material, depending on its thinness and stretchiness. The material could lead to windows that automatically adjust the amount of light that’s let in.
New York is one of my favorite places in the world because of so many things but in certain moments (especially during the winter) it can be a miserable place to live as you wonder if it’s worth it to be freezing and packed on top of people and question if the city is all a big scam. That’s why it’s nice to be…
Energy-saving bulbs may have some competition in the shape of an ageing technology. Scientists have developed a new kind of incandescent light bulb that uses modern science to ramp up its efficiency, almost matching that of commercial LED bulbs.
Imagine clothes, houses or cars that soaked up heat during the day and then released it on demand when things turned cold. That’s exactly what a new material made at MIT could provide in the future.
The blue light that emanates from your phone’s screen is known to disrupt your sleep. So it’s good news that Google has added a light filter to its Play Books app, which gradually tapers the amount of blue light used by your display as you inch closer to bedtime. Now all apps need it.
Every year, the Caretta Plaza in Tokyo is adorned with an impressive light show to mark the end of another 365 days. This time, over 270,000 LEDs are being used to create an elaborate six-minute audiovisual light show that you can see in these images.
Witnessing an aurora first-hand is a truly awe-inspiring experience. The natural beauty of the northern or southern lights captures the public imagination unlike any other aspect of space weather. But auroras aren’t unique to Earth and can be seen on several other planets in our solar system.
How do you trap light inside something that’s filled with holes? That may sound like an odd question, but it’s one that researchers have been grappling with to create a new kind of microscopic container that locks light in but lets fluids pass straight through.
Good low-light photography is one of the toughest nuts to crack: to get good pictures in the dark normally requires some combination of fast lenses and big, expensive sensors. But tweaking one filter that lives inside the camera could help big time.
It may look like something you’d use for target practice, but this is a new kind of sensor that can detect the presence of all kinds of light—and reacts to it in super-quick time, too.
A team of scientists has created what they claim is the blackest material ever produced by human hands, which absorbs virtually all of the light that hits its surface.
It’s simple enough, right? Light is light. We get it from the Sun, when we flip on the switch, or turn on the flashlight. We see it! But that explanation doesn’t really explain anything. Kurz Gesagt breaks down what light is using wavelengths and frequencies and the speed of it to explain why it’s so damn special.
You’ve never seen a camera that looks like this. Its flat black visage is like the face of some terrible spider. It’s called the Light L16, and it may not look the part of photographic tool, but it hopes to accomplish the impossible: professional quality in an (almost) pocket-sized device.
This fancy-looking slab is the world’s first optical rectenna, a small device that’s part antenna, part rectifier diode — and it’s able to convert light directly into DC current.
The Philips AmbiLux UHD grabs your eyeballs by the...er...balls and puts them through some sort of kaleidoscopic interdimensional warp hole.
People like dawn because it’s the start of the new day and the illusion of opportunity exists as light breaks the night. I like dawn because when I see the sun rise it meant I had a great night. But dusk is more my speed, the world comes alive in a completely different way. In any case, dusk and dawn are the best…
If you’ve ever wondered what it might be like to see the world as a lizzard or a bumble bee or some other animal, you’re in luck: a new peice of open access software allows you to see how other creatures see the world.
Your eyes are good—but how good? There’s a long-standing argument about the distance from which humans can observe a burning candle, but now a pair of astronomers has calculated an answer based on the science of how we see the stars.
Lasers have been advancing science and threatening move characters since the 1960s, but you may have noticed they always have a distinct color. Now, a team of scientists has developed the world’s first white laser.
