It is a mystery that has stymied astrophysicists for decades: how do black holes produce so many high-power X-rays?
It won't come as much of a surprise to most dog owners, but new research has shown that man's best friend is a lot more likely to steal food when nobody's looking, suggesting for the first time that dogs can understand a human's point of view.
Astronomers have measured the light from the very earliest stars, working out for the first time the total amount of light from all the stars that have ever shone.
NASA scientists have, for the first time, seen the light from a planet outside our solar system that's a similar size to the Earth.
Researchers at the National Institute of Standards and Technology (NIST) have worked out a way to produce light pulses that - in a way - travel faster than the speed of light.
For innumerable decades, drivers have attempted to set their vehicles apart from the rest by customizing their ride with everything from wheels to paint.
BASF and Philips have developed an OLED car roof that can flip between acting as a window and a light source, giving light when switched on but becoming transparent when turned off.
MIT's created a camera that can capture a trillion frames a second - the ultimate in slow motion, say its developers.
Scientists at Chalmers University of Technology have succeeded in creating light from vacuum.
Researchers say they've been able to control the brains and muscles of small organisms such as worms, controlling them like tiny robots.
IBM has developed a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling data transfer using pulses of light.
Physicists from the University of Bonn have developed a completely new source of light, previously thought to be impossible - a so-called Bose-Einstein condensate consisting of photons.
Cities could one day be lit by glowing trees, thanks to a discovery at Taiwan's National Cheng Kung University (NCKU).
A team of international researchers has designed a photonic chip that operates on the principle of light, rather than electricity.
An Australian team says it's developed the most efficient quantum memory for light ever, and has used it to create read-once holograms.
