On an infrared camera, a warm object normally stands out clearly against its cooler surroundings. Researchers at the University of Illinois Urbana-Champaign have now built a three-dimensional cloak that bends heat around an object entirely, erasing its thermal outline while keeping the space inside protected from extreme temperatures. Rather than blocking heat at a barrier,…
Scientists have uncovered how Posidonia oceanica adapted to the dim light of the seabed. In the Mediterranean Sea, vast underwater meadows of seagrass grow in places where sunlight is weak. Yet these plants continue to photosynthesise efficiently, produce oxygen, store carbon and suppor marine life.A new study has revealed how one of these seagrasses has…

The brown tree snake, native to parts of Australia, Papua New Guinea and nearby islands, found an environment unlike any it had encountered…
