When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
(PhysOrg.com) -- Currently, most nuclear fusion power plants are large, expensive projects that will take decades to benefit from. But a startup company in Vancouver, Canada, called General Fusion is taking the fast track ...
Cloaking devices play a pivotal role in many sci-fi television programs. Scientists are now working to take this technology from the dramatic realm of science fiction and make it real. Amanda D. Hanford, at Pennsylvania State ...
