Researchers from Duke University, MIT and Nanyang Technological University have demonstrated how sound waves can be used to detect cancer. Published in the medical journal, Small, the method has been proven to be less invasive that standard practices and efficient enough for clinical use. “Biopsy is the gold standard technique for cancer diagnosis,” Tony Jun Huang, the William Bevan Professor of Mechanical Engineering and Materials Science at Duke, said. “But it is painful and invasive and is often not administered until late in the cancer’s development.” With this new method, sound waves are set up at an angle to blood flow. As…

A team of researchers from the University of Pennsylvania have revived a classic psychiatric remedy that involves stimulating the brain with electricity, or as it’s most commonly called shock treatment. It’s not so shocking: The team conducted a “double-blind, stratified, placebo-controlled, randomized trial” with 81 healthy adults (36 men and 45 women). The test subjects were split into two groups, one receiving low-grade electrical stimulation to their prefrontal cortex for a period of 20 minutes, and the other receiving 30 seconds of a much smaller amount of stimulation followed by nothing. Neither participants nor facilitators were aware of which group…
