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 [...]

Researchers may have unlocked the future of computing by turning flat silicon chips into densely stacked 3D architectures. For decades, the semiconductor industry has boosted computing power by making transistors smaller and fitting more of them onto a single chip. That strategy has fueled remarkable advances in electronics, but it is now approaching fundamental physical [...]
