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... |

A European project funded by EU’s Sixth Framework Programme for research, called UROOF (short for Photonic components for Ultra-wideband Radio Over Optical Fiber), has high goals for data transmission and possibly many other applications in the future. The developing team, coordinated by Moshe Ran, has come up ... |

A new technology permits scientists to build minuscule light-conducting fiber optic cables out of DNA strands. This novel technique may soon open the doors for a technological revolution in the optical computer world (computers that run on light instead of electricity), or in artificial photosynthesis systems which w... |

The Venus flytrap (Dionaea muscicapula), inhabiting bogs in North and South Carolina (southeastern US) is a carnivorous plant, more known for catching and digesting animal prey (insects and arachnids) with a trap made by the terminal portion of each of the plant's leaves. The mechanism by which the trap shuts is... |

Researchers have just reached a profound conclusion: machines imitating human performances will do the same errors that we do. A vision computer program based on the human brain experiences the same optical illusions that people do, pointing to the fact that the illusions are a by-product of how during the infant sta... |

The basic idea of a plasma display is to illuminate tiny colored fluorescent lights to form an image. Each pixel (the tiny dots on the display) is made up of three fluorescent lights - a red light, a green light and a blue light - which are evenly distributed on the screen. By combining these colors in different prop... |

Tiny gold atomic arrangements called nanorods were found to be able to spontaneously assemble themselves into ring-like superstructures by a team at Rice University. Nanorods have dimensions of billionths of a meter (1,000 times less than a hair width). The nanorings could boost the development of new nanotechnologie... |

The size and efficiency of future devices relying on laser optics (like DVD players, computer circuits and laser printers) could be highly improved by a novel high-performance mirror developed by a team at University of California, Berkeley. This mirror has the same 99.9 % reflective punch as high-grade mirrors, name... |

Nature has found complex models long before humans discovered them and most of them are more effective than the human ones. The three-dimensional shells of tiny ocean algae, called diatoms, could offer the foundation for novel electronics, like gas sensor devices that could be faster and more efficient than conventio... |

Scientists have created the world's first film that has practically no reflection. This is a breakthrough compared to current nonreflective materials, and the new technology could greatly improve solar cells, empower light-emitting diodes, and boost research in quantum mechanics by imitating a "black body," an o... |
