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...]

Compact Signal and Spectrum Analyzer for High-Speed Production Testing
Rohde & Schwarz has released its new FPS signal and spectrum analyzer for high-speed production testing of wireless communications components and base station test systems. With a height of two height units (2 HU), the compact R&S FPS takes up only half as much rack space as a conventional spectrum analyzer and is available in five models for frequency ranges up to 4, … [Read more...]
Dead Spacecraft Gives Insight into ‘Bermuda Triangle of Space’
A decade-old European satellite has given Italian scientists a detailed look into a dangerous radiation zone located a few hundred kilometers above the coast of Brazil. Known as the South Atlantic Anomaly (SAA), or “Bermuda Triangle of Space,” the region has reportedly caused satellites and telescopes to malfunction and temporarily affected astronauts’ eyesight. According to … [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...]
A Report from the Southeastern Michigan EMC Fest
I recently attended the Southeastern Michigan EMC Fest, so this posting is dedicated to the show. I have a lot of admiration for Scott Lytle (Chapter Chair) and the Southeastern Michigan chapter he runs, so I decided to attend this year’s EMC Fest. The key attraction was Doug Smith, who gave attendees the benefit of his wisdom on diagnosing automotive EMC issues.The … [Read more...]
USB Micromodule Isolator with Power Protects Hubs and Peripheral Ports
Linear Technology Corporation has introduced the LTM2884, a USB µModule® (micromodule) isolator that combines USB data communications and USB power and guards against ground-to-ground differentials and large common mode transients. With its rugged interface and isolation, the LTM2884 is ideal for systems implementing USB in harsh industrial or medical environments where … [Read more...]
