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.

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

Jetlag need never again be a problem, according to two scientists from Boston's Brigham and Women's Hospital. All you need is an understanding of your circadian cycle, a strong light, and plenty of spare time. picked by suebe 4 months ago

Scientists at the University of St Andrews have used lasers to simulate a black hole in their laboratory. Professor Ulf Leonhardt and Dr Friedrich König used intense light pulses to create an artificial `event horizon' - the defining feature of a black hole known as `the point of no return'. The development may allow researchers to test Professor Stephen Hawking's theory that black holes are... read full post picked by AutumnLotus 2 years ago

In a quantum mechanical sleight of hand, Harvard physicists have shown that they can not only bring a pulse of light, the fleetest of nature’s particles, to a complete halt, but also resuscitate the light at a different location and let it continue on its way. picked by Bornbad 3 years 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

Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. picked by AutumnLotus 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

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

The basic technology used in cheap 3D postcards and novelty items has been adapted to create six-dimensional images that respond to changes in light and the viewer's direction. picked by AutumnLotus 1 year ago
