The most acute, naturally-occurring polarization vision has been discovered in cuttlefish. Apparently, these amazing creatures are perfectly capable of detecting specific polarizations of light, to which very few other living things are sensitive too.
According to a paper published in the journal Current Biology, c... |

Colorado School of Mines scientists have just create a new type of filter for circular polarized light, bringing the goal of having the ability to control all possible polarizations of visible light one step closer to reality. The achievement opens the way for several high-profile applications.
Light filters are ob... |

Investigators from the Applied Science Faculty at the Free University Bruxelles announce the discovery of a new amazing property for graphene, and namely the fact that it can polarize light. Now, Dr. Han Zhang at the Service OPERA-photonique's Applied Science Faculty, ULB, and Dr. Qiaoliang Bao (the first author... |

A team of astronomers was recently able to conduct a groundbreaking analysis on the atmosphere of a particular exoplanet, which they managed to image in several wavelengths, using various filters.This is unfortunately rather uncommon for exoplanetary research, given the vast distances that exist between Earth and any... |

Experts have been working hard on overcoming the obstacles that stand in the way of creating a fully functional quantum computer for quite some time now, but one of the main issues in their path was the fact that they could not control the actions of a single qubit (quantum bit – the basic unit of a quantum pro... |

For the first time, astronomers using a French telescope have managed to identify the influence of a magnetic field on the light emanating from the star Vega, in the constellation Lyra, some 25 light-years away from Earth. This star is arguably the most studied in the sky, because it's very close to our planet, ... |

Controlling the polarization of lasers, as in the orientation of the wave oscillation, has been a long-term objective for physicists, on account of the fact that figuring out how to do this could open new avenues of research, especially in the fields of photonics and communication. Now, an international team comprise... |

Most of you might not know this, but 3-D glasses have actually been around ever since the 1920s, reaching their peak of popularity throughout the 1950s. They are still in use even today, although not as much as they used to be. 3-D glasses rely on a technique known as stereoscopic imaging, in which 2-dimensional imag... |

It was long predicted that quasars may in fact be black holes found in the center of large discs of hot matter. However, it was never really proven through observations that this was in fact true. Confirmation now comes from a team of astronomers from the Max Planck Institute for Radio Astronomy in Bonn who used a li... |

Aurora Borealis, most commonly known as the Northern Lights, is created when cosmic rays - solar wind in special - interact with the Earth's magnetic field and the atmosphere in order to determine light emissions in the gas atoms located in the upper layers of the atmosphere. In the middle of the 20th century, R... |

You can't transfer much information with a photon, we've learned that from our experience with today's existing optic communication devices. If a single photon of light is manipulated in a classical way, then photons are not too different from electrons in the matter of information transfer, except may... |

Entangled photons are basically particles of light with interlinked properties, meaning that the properties of one photon depend on those of a second photon. The study of the interactions that take place between entangled properties may eventually reveal the fundamental concepts of quantum physics. The National Insti... |

Light emitting diodes are taking over our lives, whether you like it or not. They can be found almost everywhere starting with your average mobile cellular phone, to indoor lighting solution, lasers and even liquid crystal displays and televisions. However, although being extremely energy efficient, small and resilie... |

Magnetic avalanches could wipe clean entire hard disk drives, so a new model of this phenomenon helps explain how and why they appear, but most importantly, how to prevent them in order to create new and more reliable memory storage devices.Two magnets pushed together create an avalanche of magnetic activity, used t... |

All currently used electronic devices rely on electron charge to function and to transmit information. A new science, called spintronics, tries to switch to using their spin instead of charge, thus potentially continuing the miniaturization process that is rapidly approaching its physical limits with current technol... |

Recently, scientists were able to polarize noble gases, (rare gases like Helium, Neon, Argon and Xenon) and to take MRI machine pictures of lungs that had inhaled these gases. A new technique can polarize other elements too, with even greater benefits to medical science. Spin polarization is the degree by which the ... |
