LCD Sunglasses rejecting light with maximum efficiency
Bothered by the sun while it was driving personal car on the way to work, American physicist Chris Mullin was decided in 2002 to design a pair of glasses able to block the light through…

Hydrogen fuel from sunlight and water
Scientists have engineered a cheap, abundant alternative to the expensive platinum catalyst and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water. The discovery is an important development in the…

Optical transistor: Rotate light with magnetic field
Physicists have managed to control the rotation of light by means of a ultra thin semiconductor. The advance could potentially be used to create a transistor that works with light instead of electrical current. Light…

Asymmetric Supernovae: Not All Stellar Explosions Expand Spherically
Stars are balls of glowing gas, with a nearly spherical shape. Accordingly, one would expect that when some stars explode as supernovae at the end of their lives, the resulting colossal fireballs should share this…

A group of Italian architects invented the “transparent cement”
Innovative material has been used until now to build a single building - the Italian pavilion at the World Exhibition 2010 in Shanghai, China.From a distance, it looks like regular concrete, but, up close, you can see thousands oftiny holes that allow light through, but that does not compromise the structural strength of the material. Italcementi company has made so-called ”transparent cement”, called i.light, integrating a special blend of resins, the company created by experts. Italian Pavilion at Shanghai, 18 meters high, is built at a rate 40%, i.light, 3774 panels were used in this material, with a total weight of 189 tonnes.

Extracting Information from Starlight
The cosmos is filled with stars. However, the closest star beyond the Sun is so far away, that it would take the fastest spacecraft 75,000 years to reach it. Astronomers can’t study the cosmos by…

Quantum Leap for Phonon Lasers
Physicists have taken major step forward in the development of practical phonon lasers, which emit sound in much the same way that optical lasers emit light. The development should lead to new, high-resolution imaging devices…

How to build a tabletop X-ray laser that could be used for super high-resolution imaging
For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past…

Extreme jets take new shape
Jets of particles streaming from black holes in far-away galaxies operate differently than previously thought, according to a study published today in Nature. The new study reveals that most of the jet’s light—gamma rays, the…
