A new 3D material can guide heat around complex objects while shielding them from extreme temperatures and infrared detection. On an infrared camera, a warm object normally stands out clearly against cooler surroundings. Researchers have now built a three-dimensional cloak that bends heat around an object, erasing its thermal outline while protecting the space inside [...]
