The clever boffins have finally managed to break the speed of light. A light pulse was so fast that it "exited a specially-prepared chamber before it even finished entering it." picked by TheStep 3 years ago

Research led by the University of Warwick has found a way to use doughnut shaped by-products of quantum dots to slow and even freeze light, opening up a wide range of possibilities from reliable and effective light based computing to the possibility of "slow glass". picked by AutumnLotus 9 months ago

As soon as you are born, you are influencing light. From the day of your birth, you can see how many stars that light has reached. Works only on stars up to 50 light years away. picked by Moe 2 years ago

A glowing plaster that can patch up wounds AND destroy skin cancer cells by zapping them with light, has been unveiled by British scientists.

Not only with their traditional images, but with highly-carated art of our times the Essener Lichtwochen (Light Weeks) are brilliantly setting the scene for the „Guest Country Hungary“.Under the designation: “Cultural capitals 2010 Essen and Pécs – Hungarian accent” the artist in light Peter Kozma well-known all over Europe has created a sensational installation ... read full post picked by zoran11 12 months ago

Most seem very cheap and easy, no real tech expertise (unless you don't know how to use duct tape). picked by dollyllama 3 years ago

Using LED glow sticks, flashlights, even fireworks, combined with time-lapse photography, light graffiti artists create a unique tagging that wraps around objects dimensionally, allowing them to tag in a way they'd never be able to with spray paint. picked by Mershaullk 2 years ago

In the era of 24/7 artificial light, real darkness is hard to find. But not only stargazers are affected -- light pollution also threatens animals and even entire ecosystems.
A small drama unfolds in the skies over Germany and other industrialized countries every evening. The sun sets, and yet it remains light -- so light, in fact, that one can hardly see anything. picked by Bingo 4 months ago

Light graffiti is uniquely ephemeral and inextricably intertwined with the art of photography, sometimes even invisible to the naked eye and apparent only when captured on film. picked by Bornbad 12 months ago

During the next few weeks on some clear moonless early morning, if you are fortunate to be far from any haze and bright lights, keep a close watch on the eastern horizon about two hours before sunrise. If you're lucky you might catch a glimpse of a ghostly column of light extending upward into the sky. picked by AutumnLotus 1 year ago

A photographer swapped spray cans for torches (flashlights) to graffiti British landmarks in a set of stunning images. Michael Bosanko used long exposure shots and different coloured torches to 'draw with light' in the night-time shots. picked by Bingo 4 months ago

A Hampton University professor is shedding new light on night-shining clouds that might be affected by climate change. Jim Russell is the lead scientist for the NASA-funded AIM satellite, the first to study the wispy "noctilucent" clouds, which only appear above Earth's poles. picked by AutumnLotus 2 years ago

A primitive star has been born in the heart of a computer, revealing how the basic building blocks of life were present soon after the Big Bang some 13.7 billion years ago. Stars convert light elements such as helium and hydrogen into the heavier elements necessary for life and it has often been remarked that human beings are glorified stardust. picked by AutumnLotus 1 year ago

Two papers, from teams led by Xiang Zhang at the University of California, Berkeley, this week report on new nanomaterials, which have been especially designed to bend light the wrong way. By reversing refraction, they can in principle make objects invisible to the wavelengths of light we use to see. picked by ceflory 1 year ago
