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

To understand the units of time we need to investigate the number systems of ancient civilizations. How did the Sumerians count to 12 on one hand and to 60 on two? What advances did the Babylonians make and how did they use this number system for measurement? And what refinements did the Egyptians make to time measurement to give us the system we still use today? picked by AutumnLotus 5 months ago

Astronomers have measured the brightness of a supernova that flashed and faded 400 years ago, thanks to a lucky alignment of dust clouds that has provided a replay of the event. VIDEOS included. picked by AutumnLotus 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.

The strip of bendy plastic is embedded with light-emitting diodes that blast a high-powered of beam of red light onto tumours. picked by AutumnLotus 7 months 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

Due to the increase in overweight children, the government in the UK is introducing "The National Child Measurement Programme."

If parents agree to their kids being weighed they will receive a letter to let them know if their child is overweight and advice on how to help them lose weight. picked by DoggyLives 1 year ago

It was supposed to be the one speed limit you cannot break. But scientists claim to have demonstrated there is the possibility of travel faster than the speed of light. picked by AutumnLotus 2 years 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

The wonderland known as Yellowstone National Park has yielded a new marvel an unusual bacterium that converts light to energy. The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth. picked by AutumnLotus 2 years 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 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

Science knows you can move a solid with the heat generated from a light source. This discovery shows that light actually exerts a physical pressure capable of moving solid matter. picked by BrownTrout 3 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

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

Visiting aliens may be the stuff of legend, but if a scientific team working at the National Institute of Standards and Technology is right, we may be able to find extraterrestrial life even before it leaves its home planet—by looking for left- (or right-) handed light. picked by AutumnLotus 7 months ago

The world's biggest maker of photographic film says its proprietary sensor technology significantly increases sensitivity to light. Image sensors act as a digital camera's eyes by converting light into an electric charge to begin the capture process. picked by DrNothing 2 years ago
