When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or ...
In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials ...
Abstract: Experiments carried out at NUWC's Seneca Lake facility in the summer of 2020 demonstrate the efficacy of underwater navigation via a single spiral wavefront (SWF) acoustic beacon. An SWF ...
Abstract: The beam profile and wavefront characteristics of laser beams are essential for numerous laser applications, including micromachining and microfabrication. However, conventional wavefront ...
Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid—normally defined by its ...
