Storing Cell Phones in Your Front Pocket Could Lower Sperm Count, New Study Suggests
A recent meta-study conducted at the University of Exeter in the UK suggests that radio-frequency electromagnetic radiation (RF-EMR) emitted from cell phones kept in the pockets of men could be a major factor in the modern world’s fast-dropping sperm count. The study, "Effect of mobile telephones on sperm quality: a systematic review and meta-analysis,” led by Fiona Mathews, … [Read more...]
Using Magnetic Fields to Track Footballs
Sports officials may soon have a better way of determining whether a football team has achieved a first down or scored a touchdown. Researchers from North Carolina State University, Carnegie Mellon University and Disney Research have developed a new system capable of accurately tracking a football in three-dimensional space using low-frequency magnetic fields. The new … [Read more...]
Cell Phone Use for ½ Hour Per Day Linked to Increased Brain Cancer Risk
In a recent study conducted at the University of Bordeaux, researchers have found that using a cell phone for 15 hours a month, or roughly half an hour a day, can lead to a two to three times increase in a person’s chances of getting a brain tumor. The French study, published in British Occupational and Environmental Medicine, centered on 253 cases of glioma – a type of tumor … [Read more...]
Marijuana-Growing Lights Interfere with Amateur Radio
The American Radio Relay League (ARRL), the national association for amateur radio, has filed a formal complaint against a certain type of lighting system used to cultivate marijuana after determining it interferes with MF and HF radio bands. The ARRL said that the ballasts in certain lighting devices like the Lumatek LK-1000, which are increasingly popular among marijuana … [Read more...]
Double-Duty Electrical Cables Can Store Energy
Scientists at the University of Central Florida have developed a way to both transmit and store electricity in a single lightweight copper wire. Jayan Thomas, a professor at the University of Central Florida, and Ph.D student Zenan Yu created a supercapacitor on the outside of a copper wire as a means to store energy while allowing electricity to continue passing through the … [Read more...]
British Aristocrat Claims RF Interference in Drunk Driving Arrest
The recent court case of a British aristocrat with close ties to Princes William and Harry has once again highlighted the issue of breathalyzer radio frequency interference. Nightclub owner Guy Pelly was pulled over while driving his Audi R8 GT V10 Coupe through central London last May after reportedly visiting one of his exclusive clubs. The 32-year-old reportedly refused to … [Read more...]
Chip Cancels On-Channel RF Interference
Researchers at the University of Twente in the Netherlands have created a new chip designed to cancel on-channel interference using an adaptive beamforming technique. While the ability to make such a device has already existed for some time, the UTwente chip can be manufactured more cheaply and economically than any of its predecessors. The device, developed by postgraduate … [Read more...]
