Electromagnetic Fields Could Delay Alzheimer’s Disease in Rats

 

A team of researchers in China have published a study that suggests exposure to extremely low frequency electromagnetic fields (ELF-EMF) delays the development of Alzheimer’s Disease (AD) in rats. The study, titled “Improvement of Spatial Memory Disorder and Hippocampal Damage by Exposure to Electromagnetic Fields in an Alzheimer’s Disease Rat Model” was published in the … [Read more...]

FCC’s Plan to Revitalize AM Radio Concerns Listeners

 

On May 15, iHeartMedia met with the FCC Media Bureau to discuss the current plan to revitalize AM Radio and to discuss an ex parte letter describing possible changes to AM radio stations. The plan in place will reduce skywave interference protection which make it easier for AM radio stations to operate and give users more flexibility. Jeff Littlejohn of EVP/Engineering and … [Read more...]

Anti-jamming Technology Effective in Protecting Satellites from Interference

 

Boeing Engineers have tested an anti-jamming technology for satellites that shields signals from interference and have proven the technology is capable of operating both on the ground and in a satellite-based networking hubs. The test was completed under a contract for the U.S. Air Force Space and Missile Systems Center and was supervised by the U.S. Government. It was … [Read more...]

Astronomers Discover 17-Year Interference Caused by Microwave Oven

 

For nearly 17 years astronomers at Parkes Observatory in Australia searched for the reason why radio interference took place during experiments and observations. They discovered early this year that the interference was coming from a microwave oven in the observatory’s kitchen. Parkes Observatory houses one of the best-known radio telescopes in the country. It is used to … [Read more...]

Maglev Hovering Train Breaks Speed Record

 

A seven car Maglev (magnetic levitation) Train in Central Japan broke its own speed record when tested near Mount Fuji this week. In 2003 the Maglev’s record was 268 mph and last week it reached 366 mph. On Tuesday the Maglev surpassed both previous records and reached 374 mph. The Maglev train hovers four inches above the tracks and is propelled by electrically-charged … [Read more...]

Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking

 

Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]

FBI Pulled Security Expert from Flight for Alleged Hacking Concerns

 

The FBI pulled Chris Roberts, a computer security expert, from his United Airlines Flight last Wednesday in Syracuse because of suspicions that he hacked the airplane. Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]

Series of Shielded High-power Inductors Not Affected by Thermal Aging

 

Coilcraft introduces a new series of shielded high-current power inductors. The MLC75xx Series offers advanced handling, low DCR, Isat ratings up to 59.2 Amps, DC resistance down to 1.2 mOhms, and a reflow temperature of 260 degrees Celsius. They are made of RoHs compliant tin-silver with copper terminations and are not affected by thermal aging. The inductors are ideal for … [Read more...]
