The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ties up one of the ...

Two teams of researchers, one in Korea, the other China, have devised two different types of invisibility cloaks for water applications. Both teams have published papers describing their work in the journal Physical Review ...
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter.
