A recent study of gamma-ray bursts by Professor Robert Nemiroff and his colleagues at Michigan Technological University provides the first strong evidence concerning the small-scale smoothness of spacetime. Oddly, this examination of the very small is accomplished by measuring a handful of gamma-rays after they traveled over ten billion light years.  Read More

The GH-LED10WBW is intended for use in emergencies, and for recreation

Every now and again, a rumor crops up that someone has invented a motor car that runs on water. Sadly, that still remains a rumor, but Green House Co Ltd of Japan will soon be marketing an LED lantern that runs on saltwater.  Read More

In Sir Arthur C. Clarke’s 1972 novel Rendezvous with Rama, the explorers of a seemingly deserted alien spaceship passing through our Solar System encounter a strange three-legged creature that turns out to be an organic robot. In the ‘70s, this seemed so incredible that it could only be the product of an alien civilization thousands of years ahead of us. In 2012, scientists at MIT and the University of Pennsylvania are proving otherwise by starting work on organic robots here on Earth. Using genetically engineered muscle tissue that responds to light, they are blurring the line between animal and machine at the cellular level.  Read More

When people have a difficult problem they often talk about “shining a light on it.” Creating and controlling high-temperature superconductors has been a problem for scientists and engineers for over two decades. Now, Yoram Dagan, a professor at Tel Aviv University's (TAU) Department of Physics and Center for Nanoscience and Nanotechnology, has made a breakthrough in superconductors by literally shining a light on them. By doing this, he is able to control their properties.  Read More

EcoXPower converts pedal-power into electricity for both headlights and a smartphone

EcoXPower by EcoXGear is another take on a concept which most Gizmag readers will be familiar with: harnessing the kinetic energy produced while one pedals a bicycle in order to convert it into electricity and charge a smartphone or similar device. Though we’ve covered several products of this nature in the past, such as Nokia's Bicycle Charger Kit, Dahon's BioLogic ReeCharge, and the PedalPower+, the EcoXPower sets itself apart by charging your smartphone or GPS and providing electricity to front and rear lights at the same time.  Read More

It's safe to say that almost anyone who has played a video game has felt the pull of Tetris at some point. There's just something about the simple, yet addictive puzzle game that draws people in for hours and has even prompted MIT students to recreate it with a whole building. Now, inspired by the classic game, the Tetris Light lets you create your own pixelated lamp out of colored blocks that light up when stacked on top of each other.  Read More

Liquid crystal video projectors could be getting smaller, more energy-efficient, and less expensive. Currently, such devices require polarized light for the projection of images. Unfortunately, conventional LEDs only produce unpolarized light. While an optical filter is typically used to polarize it, the polarization process wastes over 50 percent of the original light, converting it into heat instead of allowing it to pass through. That heat, in turn, must be dissipated using a noisy, power-consuming fan. Now, however, researchers have created a new polarizing system that allows almost 90 percent of the LED light to be converted to usable, polarized light.  Read More

We’ve seen a number of next-generation display technologies emerge in recent years, such as Sony’s “Crystal LED,” Uni-Pixel’s time-multiplexed optical shutter (TMOS) technology, and quantum dot LED (QLED) display technology from LG and QD Vision, and now there’s another one to add to the mix. While displays based on the new “spintronic” OLED technology invented by physicists at the University of Utah are still some years off, the researchers say they should be brighter, cheaper and more environmentally friendly than the LEDs found in the current crop of TVs, computer displays, traffic lights and other electronic devices.  Read More

Spectators turned out in the hundreds to witness the light show that marked the climax of the inauguration of Europe's tallest building, the 309.6-m (1016-ft) Shard in London. A dozen emerald-green laser beams emanated from the Shard to pick out iconic landmarks including the London Eye, St. Paul's Cathedral and Tower Bridge. The tower's 95 floors were lit up with color-changing lighting, and 30 search lights flared outwards and upwards from surrounding buildings.  Read More

With many of us spending more and more time indoors, it can be a struggle to get the amount of sunlight our bodies crave. Modern heat-insulating, sun-protection glazing doesn’t help, as it reflects a noticeable percentage of the incident sunlight in the part of the spectrum that governs our hormonal balance. Researchers at the Fraunhofer Institute for Silicate Research (ISC) have developed a coating for windows that lets in more light, in particular those wavelengths of light that have a beneficial effect on our sense of well-being.  Read More
