Did you know that lasers can switch each other off, producing a blackout of sorts? That's OK, neither did anyone else until experts from Yale University, Princeton University, ETH Zürich and the Vienna University of Technology discovered that this laser-effect is actually real.
Unlike conventional light b... |

Ever since micro- and nano-technology first appeared, there has been a steady strive on the part of researchers to develop ways of manipulating structures formed at such small scales. The efforts have grown considerably once experts have started realizing that nanostructures – billionths of times smaller th... |

Experts at the US Department Of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) recently reported the creation of a new class of nanocrystals, perfectly able to store carbon dioxide. The non-toxic, magnesium oxide particles can also emit blue light very effectively, and their creators hope to... |

Optical computers have been envisioned for quite some time now, but creating one is not as easy as dreaming about it. There are a number of obstacles to be overcome in this endeavor, and one of the largest is the size of the transistors making it up. But this shortcoming may have been resolved, as researchers from ET... |

In recent times, integrated optofluidic platforms have proven their worth in analyzing bacteria, viruses and other particles on a chip, but their performances are about to increase considerably. Experts at the University of California in Santa Cruz (UCSC) have created a new type of optical particle trap, which can mo... |

The Gran Telescopio Canarias (GTC), or the Great Telescope Canary Islands, is the largest optical observatory completed in the world to date. With its 10.4-meter aperture and its exquisite position some 2,400 levels above sea level, on top of a volcano, the telescope is best equipped to handle optical images, and can... |

Located about 1,600 light-years away from the Earth, in the Constellation Monoceros, the exoplanet CoRoT-1b, first discovered about two and a half years ago, is the first one whose day and night cycles were observed in optical wavelengths, as it orbited its star. The body was first discovered by the French CoRoT (Con... |

Creating constantly emitting light sources from individual molecules has been something that experts have been trying to do for more than a decade, but a small inconvenience, an optical quirk known as “blinking,” has made these efforts futile. Now, researchers at the University of Rochester (UR) have mana... |

In laser sciences, the photoelectric effect is a phenomenon that explains why stimulated light can rip electrons from their orbits around atomic nuclei and carry them away. But this theorem is about to be rewritten, some physicists say. In recent tests, they have noticed that, when using very powerful UV lasers, not ... |

Optical materials have been stretched to the maximum limits of their abilities over the years, but now researchers say that it's time for another class of materials to take their place. Apparently, that class of materials will be nanoparticles, as they seem to have the ability to distort and bend light in ways t... |

Researchers at Duke University who are currently working on new ways of diverting large portions of the visible light spectrum through artificial so-called “invisibility cloaks,” announced recently that a functional prototype could be available in less than six months, if the pace of their innovation cont... |

According to recent investigations, Iraqi scientist al-Hassan Ibn al-Haytham is the father of optics and the scientific method, having experimented with both of them around the year 1,020, which is more than 700 years ahead of Newton's time. The reason why this is unknown to Western teachers and professors is th... |

Pirated CDs and DVDs are a major dent in profits for large companies, considering the fact that some countries use stolen software on 70 to 80 percent of its market. This means that no revenues enter the pockets of the manufacturer, while its products are widely used. Now, scientists at the University of Granada ... |

Microscopes are not exactly devices you would like to carry around in your pocket all day. They are generally bulky, require proper light sources, are fragile and last but not least, they are expensive. Their place is in the laboratory, not on the road. A new invention could make microscopes not only extremely small ... |

The IT industry has worked hard during the time in order to achieve the fastest hardware in the tiniest space possible. Miniaturization was the key, but times are changing and things cannot be pushed beyond anymore, due to the materials' physical limits. Light is promising to offer what matter cannot; it's ... |

There are some things that changed little or not at all since the first compatible x86 computer rolled out the assembly line. Other things change many times with the years, while other simply disappeared and were replaced by other hardware parts and standards.One of the most stable things in the entire computer indus... |

Lenses are used to converge or diverge light in various optical and electronic devices and the first written records of the use of a lens date to Ancient Greece, in 424 BC. The optical zoom lenses in professional television cameras can have a magnification ratio as high as 100x.There are some things that a single mi... |

Colloids have been used for over 3,000 years, since the invention of ink, but only recently have scientist been able to decipher some of their unique properties. They are heterogeneous mixtures made of tiny particles or droplets that visually appear to be homogeneous solutions, meaning that they are in fact a mixtur... |
