Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at Caltech.
Exposing leafy vegetables grown during spaceflight to a few bright pulses of light daily could increase the amount of eye-protecting nutrients produced by the plants, according to a new study by researchers at the University of Colorado Boulder.
Every second, your computer must process billions of computational steps to produce even the simplest outputs. Imagine if every one of those steps could be made just a tiny bit more efficient. “It would save precious nanoseconds,” explained Northeastern University assistant professor of physics Swastik Kar.
A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say.
Researchers from the University of Pennsylvania have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.
Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light’s path.
There are several ways to "trap" a beam of light — usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications.
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).
