Innovative wireless split-ring resonator concentrates microwaves into a hot-spot for ultrasound emission SPIE–INTERNATIONAL SOCIETY FOR OPTICS AND PHOTONICS Ultrasound imaging is one of the workhorses in a modern hospital. It hits the trifecta of being relatively cheap, portable, and non-invasive. The ability to cause future parents to get a bit emotional over fetus images is...
According to a new paper by the American Academy of Pediatrics, many people overlook seemingly minor mistakes that pose serious food safety risks, such as microwaving or dishwashing plastic containers that contain harmful chemicals. In a new study published online, pediatricians highlighted a growing number of evidence against food packaging materials, in addition to food colorings...
Before lasers, there were masers — the microwave siblings of optical lasers. But whereas lasers are used in many applications from telescopes to medicine, masers have long languished in the shadows, because they work only in super-cool temperatures or in a vacuum. Now, physicists have created a maser that works in regular conditions — using...
