British Researchers to Study Effects of Cell Phones on Teen Brain Development
Scientists in the UK are conducting the largest study to date on the effects of cell phone usage on adolescent and teenage brain development. The study, called SCAMP (Study of Cognition, Adolescents and Mobile Phones), will follow a group of 2,500-3,000 students in the greater London area, charting changes in brain development from Grade 7 to Grade 9. SCAMP’s mission, stated … [Read more...]
Combining Near- and Far-Field Waves to Power Medical Devices
Video: Stanford University in California Researchers have demonstrated a method of transferring wireless energy to a medical device implanted inside a living animal. The new system, which uses the same amount of power as a cell phone to transmit energy to implanted chips roughly the size of a grain of rice, is the culmination of years of work by Ada Poon, assistant professor … [Read more...]
More Research into Cancer-Radio Waves Link Needed, Says Canadian Panel
An expert panel reviewing Canadian safety limits for exposure to radio waves has concluded that existing standards appear sufficient and that there is no clear evidence of risks from lower exposure. The independent panel convened by the Royal Society of Canada issued its report Tuesday on Health Canada’s Safety Code 6, which sets limits on exposure to radio frequency fields … [Read more...]
Converting Radio Waves into Light
Scientists in Denmark and the US have developed a new approach to detecting and strengthening ultra-weak radio signals they say could benefit a range of industries. According to the researchers, detecting extremely weak radio waves is key to many modern technologies, including satellite navigation, long-distance communications, radio telescopes and magnetic resonance imaging … [Read more...]
Portable Suction Devices May Interfere With Defibrillators
New research from scientists in the UK suggests that electromagnetic radiation from portable suction devices could interfere with some defibrillators, rendering them inoperable in a medical emergency. According to Siu-Man Lee, Ph.D. from the Royal United Hospital Bath, Philips HeartStart MRx defibrillators are known to fail without warning during battery power operation if … [Read more...]
ESD Simulator Pistol Upgraded with Color Touchscreen Display
Teseq, a developer instrumentation and systems for EMC emission and immunity testing, has enhanced its NSG 438 electrostatic discharge (ESD) simulator to include a new color touch display, allowing users to change settings and features right on the pistol. The NSG 437 ESD simulator also includes this unique, new feature. Reportedly the first ESD pistol on the market with a … [Read more...]
