New metamaterials can change properties with a flick of a light-switch
Invisibility cloaks have less to do with magic than with metamaterials. These human-engineered materials have properties that don't occur in nature, allowing them to bend and manipulate light in weird ways. For example, some ...

Scientists move one step closer to creating an invisibility cloak
Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a composite material with nano-size particles that can enhance specific properties on the object's surface.

Insects were already using camouflage 100 million years ago
Those who go to a masked ball consciously slip into a different role, in order to avoid being recognized so quickly. Insects were already doing something very similar in the Cretaceous: They cloaked themselves in pieces of ...

Closer look reveals how deep ocean squid uses 'leaky' optical fibers to disappear into the background
(Â鶹ÒùÔº)—A pair of researchers with the University of Pennsylvania has discovered how a type of deep ocean squid is able to remain unseen by predators despite having clearly visible eyes. In their paper published in Journal ...

A digital Rochester Cloak to fit all sizes
Using the same mathematical framework as the Rochester Cloak, researchers at the University of Rochester have been able to use flat screen displays to extend the range of angles that can be hidden from view. Their method ...

How could we build an invisibility cloak to hide Earth from an alien civilization?
What would it take to hide an entire planet? It sounds more like a question posed in an episode of "Star Trek" than in academic discourse, but sometimes the bleeding edge of science blurs with themes found in science fiction.

Invisibility cloaks can never hide objects from all observers
(Â鶹ÒùÔº)—Ideal invisibility cloaks like those in Harry Potter may be physically impossible, a new study shows. The researchers demonstrate that even the best invisibility cloaks can hide an object from only some observers, ...
