Photons – the basic particles that make up light – have a tendency to move about unimpeded, and in whichever direction they choose. But new materials currently being developed could allow experts to create one-way streets for light, in which photons travel in a single direction.These nonlinear materials c... |

A collaboration of scientists from the US National Institute of Standards and Technology (NIST), and partners in the industry and academia, was able to develop small-scale antennas that acted just like the real deal. In fact, the innovative devices are so good at what they were built to do, that there is no significa... |

Over the past few years, concerns about the environmental impact of incandescent light bulbs have generated furious debates among scientists and policy makers in regards to their efficiency and the carbon footprint they leave behind. These talks have eventually led to a new legislation, which has phased out conventio... |

As the quest for the smallest material and basic components of matter accelerates, scientists around the world are currently faced with a more and more pressing issue – the lack of appropriate means of investigating single atoms and molecules. They require a tool that can detect even the smallest amounts of mov... |

A newly-developed material made of optical fibers could soon lead to constructing laser devices operating at more different frequencies simultaneously.The newly-created material (cesium zirconium phosphorus selenium - CsZrPSe6) is able to add, subtract or double laser beam wavelengths, thus allowing for the deve... |

Determining the properties of conventional lasers is relatively easy and can be done with the help of computer simulations, but when it comes to non-conventional lasers not even simulations can help determine the lasing mode and ultimately the properties of the laser. However it may be possible to predict them with a... |

All previous invisibility cloak projects claimed at some point in time that a three-dimensional optical light cloak can be built. I won't deny that this is true, although I haven't bumped into any invisible objects lately which leads me to believe that this attempt has failed. Now, a new three-dimensional o... |

Conventional lenses, no matter how powerful, are only able to magnify light to nearly half of the wavelength, or the so-called diffraction limit. This basically means that the dimensions of optical storing devices or the sizes of the features created on silicon chips are limited to how much focusing power a particula... |

Colors have various physical and psychical influences on the body, and they can manipulate our mood. A common rule says an individual prefers the light wavelength (colors are nothing more than different values of the light wavelengths) retrieved in its energetic structure. Different energetic structure are impacted d... |

Pumpkin seed oil is a specialty used in the Styria region of Austria and the Lower Styria, in Slovenia. Although used for centuries by the local population, a weird property of this oil could not be explained until now.This oil seems to change color for no apparent reason, depending only on the container. The visco... |

NIST, the National Institute of Standards and Technology, in the US, has presented a prototype network that is the first capable of remote synchronization of light waves from two "frequency combs"-advanced laboratory tools for precisely measuring frequencies of light.It's a flexible network design that can be t... |

US is a huge energy consumer, be it nuclear energy, hydro-electric or energy produced with fossil fuels. Buildings are responsible for a third of the total energy consumption, of which 25 to 40 percent are spent for running electric lights.Electrical lighting was definitely one of the most important inventions of ma... |

Earth's land is covered by the green of the plants, but NASA researchers warn that this is linked to the conditions on the Earth and plants on extra-solar planets could confer them green, yellow or red-dominant hues.Astronomers believe plants on other planets reflect mostly other colors than green. "We can ident... |

Researchers have employed nanotechnology on the way towards the creation of an invisibility device that could make objects invisible. A Purdue University team has made a theoretical design that employs an array of tiny needles radiating outward from a central spoke, which would bend light around the cloaked object. "... |
