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

Two teams have independently succeeded in placing a cloud of chilled rubidium atoms within an optical cavity, which traps light between two opposed mirrors. The combination could one day form a quantum memory element. picked by drnothing 2 years 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.

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

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

Researchers have found a way of creating bright light from cheap, commonplace resources like the zinc oxide found in nappy (diaper) rash powders and sunblock. picked by pocksucket 11 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

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

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

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

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

(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed on a photonic chip and it is major step forward in the quest to realise a super-powerful quantum computer. picked by kakana 3 months ago

Astronomers believe they may have discovered the brightest star in the Milky Way amid a swirling cloud of colourful stellar dust.
