Latest Cloak of invisibility Stories
Researchers have overcome a fundamental obstacle in using new "metamaterials" for radical advances in optical technologies, including ultra-powerful microscopes and computers and a possible invisibility cloak.

Powerful new microscopes able to resolve DNA molecules with visible light, superfast computers that use light rather than electronic signals to process information, and Harry Potteresque invisibility cloaks are just some of the many thrilling promises of transformation optics.
Scalable devices inspired by nature exhibit customizable optical properties suitable for applications ranging from highly sensitive sensors and detectors to invisibility cloaks.
Researchers have successfully rendered a minute bump on a gold surface invisible, using special masking technology that could someday bring true invisibility cloaks from the realms of science fiction and fantasy into reality.
Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually.
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek."
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway.
Chinese physicists may not yet be able to move between parallel universes or become invisible, but they've created the first tunable electromagnetic gateway. Researchers at the Hong Kong University of Science and Technology and Fudan University in Shanghai said their concept of a gateway that can block electromagnetic waves, but that allows the passage of other entities resembles hidden portals or invisibility cloaks mentioned in works of science fiction or fantasy, such as the Harry Potter...
Schools and hospitals could one day be protected from feeling the effects of an earthquake. CNRS researchers at the Institute Fresnel in Marseille (1) have come up with a system that could protect buildings from the most destructive seismic waves
