UUltrasound is a powerful tool for looking inside the body. The scans see through layers of tissue to reveal pumping hearts, developing fetuses, troublesome blood clots, and injured muscles. They are relatively low-cost, portable, and have few side effects. Patients aren’t exposed to ionizing radiation or confined in a small space. They are, however, slathered

Invisible nuclei: acoustically induced transparency allows gamma rays to travel through a sample of otherwise absorbent iron. (Courtesy: iStock/Andrey Prokhorov) Iron nuclei can be made transparent to gamma rays that they would normally absorb using a new technique called “acoustically induced transparency” (AIT).  This feat was achieved by physicists in the US and Russia, who

At first glance, the sprawling industrial site, covering roughly 900 acres in Kingsport, Tennessee, appears to be just another chemical manufacturing facility. There are hundreds of buildings and countless miles of pipes, conveyors, distillers, cooling towers, valves, pumps, compressors and controls. It doesn’t exactly look or feel particularly noteworthy. But something extraordinary is going on
