Key Points and Summary - That dramatic “smoke” around the F-22 isn’t a sci-fi cloaking device—it’s a vapor cone. -During high-G or near-transonic maneuvers in humid air, pressure drops cause moisture ...

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.” Instead, the ...

“Invisibility cloaks” have been in development for years, but keep hitting a major roadblock — the materials used absorb too much light. New research may have found the trick to get around that, and ...

From cloaking devices that conceal spaceships, to Harry Potter’s hand-me-down disappearing blanket, or even the One Ring and its power to conceal its wearer, invisibility is a staple in science ...

The theorists who first created the mathematics that describe the behavior of the recently announced “invisibility cloak” have revealed a new analysis that may extend the current cloak’s powers, ...

Researchers make a cloaking device that is more than a theoretical dream, but not exactly cloaking as the trekkies among us know it.<BR><BR><a href='http ...

Duke University has built the first 3D omnidirectional acoustic invisibility cloak. The cloaking device, which takes the form of a pyramid of perforated plastic, is hidden from sound waves striking it ...

DARPA, the governmental department that researches crazy things that may eventually make it into the military, is currently working on an “ultrasonic curtain”. In layman’s terms, it’s a sonic cloaking ...

Invisibility and cloaking devices gained significant interest amongst scientific communities two decades ago, when researchers from Duke University and Imperial College London theorized that light can ...

Physicists Moti Fridman and colleagues at Cornell University (Ithaca, NY) have successfully demonstrated a time-cloaking device that can “hide” time for 15 trillionths of a second. In a paper ...
