Invisibility (sort of)

The concept of invisibility has long been thought to be entirely for movies of monsters and magic, but recent developments in science may bring this into the realm of possibility. The researchers at UC (university of California) Berkeley have created materials which have the ability to bend light in unnatural directions. These materials are called metamaterials, which are man made materials which derive their unusual properties from their structure as opposed to composition. This is to say that the literal form of the materials is what gives them their unusual characteristics.
What these materials do specifically is achieve negative refraction. Negative refraction is the term used to describe what happens when light is bent. No material in nature has negative refraction, and a simple example of what it would do if it were in nature involves fish. When you look at a fish underwater you know instinctively that it is not precisely where it appears to be, that it is skewed by the refractive quality of light when entering or exiting water. If negative refraction were taking place you would see the fish upside down and floating above the water.
So while the researches at UC Berkeley have figured out a way to bend light they have yet to make it widely applicable, such that the materials they have at the moment are simply too small and too fragile to be used in any sort of invisibility cloak. What they have been able to do with these materials, however, is put them to use in making stronger lenses for magnification purposes, cutting out interference in antennas, and reversing the Doppler effect.
