Introduced by electrical engineers from the University of California, San Diego, a new wireless communication method works by sending magnetic signals through the human body, and offers a lower-power, ...

For most of modern science, humans were believed to lack any ability to sense Earth’s magnetic field. Magnetoreception was considered a specialised adaptation found in migratory birds, sea turtles, ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...
