Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]
Radio Interference May Cause Malfunction in Amtrak’s New Anti-crash System
Amtrak is working on an anti-crash system to prevent high-speed derailments, like the fatal derailment in Philadelphia P.A. last month that killed eight passengers, injured hundreds and caused more than $9.2 million worth of damages. However, the anti-crash system may malfunction near freight railroads. Radio interference from freight rails may disable Amtrak’s anti-crash … [Read more...]
NASA Developing Early Warning System for Solar Flares
NASA has announced it is developing an early warning system for solar flares to give the Earth more time to prepare for storms, thus reducing damage. Scientists from both NASA’s Goddard Space Flight Center and Imperial College London published their research and experiments in Space Weather in the June 9 edition.

Fluid Operated Computer uses Electromagnetic Fields to Perform Operations
A group of engineers from Stanford University have produced the first ever water operated computer. The computer uses electromagnetic fields to pump water droplets impregnated with magnetic nanoparticles into gates to perform complex logical operations. Manu Prakash, a Stanford assistant professor, spent almost an entire decade thinking about the possibility of a … [Read more...]
Electromagnetic Catapult Successfully Launches Dead Load Truck into River
Earlier this week, the U.S. Navy began dead load testing the Electromagnetic Aircraft Launch System (EALS) on the Gerald R. Ford CVN 78. The electromagnetic slingshot launched an 80,000 pound dead load truck into the James River in Virginia. The truck reportedly weighed as much as a jet. Even though the truck wasn’t airborne for too long before hitting the water, the test … [Read more...]
Blog Asks: Are Cell Phones Harmful to Human Health?
Electromagnetic radio frequencies emitted from cell phones and other electronic devices remains a topic of debate due to possible health concerns. Cell phones produce low levels of non-ionizing radiation. Thus far, “extensive research into the health effects of these devices has only produced inconclusive evidence,” according to VOA News. The wireless industry and other … [Read more...]
