Although it was the “Harry Potter” series which made invisibility cloaks stunningly popular, the fact remains that, ever since humanity first came about, many people have fantasized about how cool it would be if they could just completely blend in with their surroundings.

Anyone wondering how long it will take for a true cloak of invisibility to be created, should probably start to accept that it will take a long time, but that does not mean progress isn't being made.It may just be that a new method of making something invisible, or at least simulating invisibility, has been fou... |

In the near future, spies and top-secret agencies could have a lot to benefit from a new class of nanoparticle inks that was just created. Messages written with the new substance have a tendency to make themselves invisible, when viewed by suspicious strangers. The innovation, created by experts at the Northwestern U... |

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... |

Uber-fast computers operating 1,000 times the actual speed, 10 times more powerful magnifying microscopes, able to spy on the DNA directly, more efficient solar energy capturing devices, enhanced sensors or invisibility cloaks are only a few of the goals that the new optical science field promises to achieve. If prop... |

Scientists have built a device that, if applied to larger scales, would allow ocean waves, even those as big as a tsunami, to travel through a large structure (an offshore platform or even an island) without the waves or the respective structure being altered at all.Invisibility doesn't just refer to light and v... |

Metamaterials have the unique capability of experiencing negative refractive indexes, thus literally refracting light through themselves without reflecting any to the source, therefore making any object hidden behind it invisible. This is not available only for light, acoustic waves can be also manipulated in similar... |

For nanoparticles this time though. Researchers from the Carnegie Mellon University's Material Science and Engineering and Chemistry have succeeded in partially cloaking nanoparticles by 'shrinking' their visible size without affecting the physical dimension of the particle. The study was conducted by ... |

Indeed there is. Warships may seem rather powerful, but this showoff of sheer power would not be very efficient against people that don't give a penny on looks. What the modern warfare needs is invisibility. You might have noticed the trend followed by a series of armies around the world, starting with the devel... |

Let's not fool ourselves, invisibility cloaks have been built and they do exist; they don't work exactly as they should is another thing. However, Duke University researchers said they hadn't done enough to improve the technology and decided to test some acoustic invisibility devices before resuming th... |

The universe is a world of infinite possibilities. Well, at least theoretically. Theoretical physics predicts anything from parallel universes to time travel. But, as we came to find out, neither of these two concepts are really so easy to prove. Invisibility cloaks are not different. Although physicists clearly show... |

Magic has turned into reality. A remarkable achievement has been made by an American team: the world's first real invisibility cloak, a device turning an object invisible in the visible spectrum. But don't get your hopes up: the technique works only in two dimensions and on a tiny scale so far.The new cloak... |

The invisibility is descending from fiction and movies to reality. New measurements show how to build an electromagnetic "wormhole", an invisible tube from both sides, that allows the light to pass down the unseen center. The idea is based on the technology of the spherical invisibility cloak proposed in 2006. An inv... |

The subject of invisibility has been obsessing human beings ever since they were able to imagine how it would be like to be unseen by others. Mythology is full of examples: the ring of Gyges is described in a story in Plato's The Republic. A peasant finds a ring in the tomb of a dead king which allows him to b... |

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. "... |

The glass or plastic lenses in your eyeglasses redirect, or bend light into the right direction to focus it when your own eyes are no longer capable of doing so.When looking through a lens that is not fitted to your eye, the image looks distorted to a small angle, exactly like looking at a straw emerged half way in w... |

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... |
