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... |

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. "... |
