Along the vast ocean floor lives a species of glass sponge known as Venus’ flower basket. Though delicate-looking,

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 [...]

A new passive technology could help future wireless networks reach places where signals struggle today. Dead zones are one of the most persistent problems in wireless communications. Whether it’s a basement office, a warehouse aisle, a tunnel, or a crowded indoor venue, signals often struggle to reach every corner. The challenge is expected to grow [...]
