New Magnetic Material Could Boost Hard Drives, Protect Electrical Grids
Scientists at the University of California, San Diego have developed a highly sensitive magnetic material they say could drastically change computer hard drives and electrical grids. Made of thin layers of nickel and vanadium oxide, the material is extremely responsive to heat and requires only a small shift in temperature to alter its magnetic properties. "We can control the … [Read more...]
Man-Made Electromagnetic Noise Disrupts Bird Navigation
Scientists have known for decades that migratory birds orient themselves using the Earth’s magnetic field in order to fly in the right direction. Now, German researchers have documented for the first time that man-made electromagnetic radiation interferes with these birds' internal compasses. The phenomenon was discovered by Henrik Mouritsen, a professor of neurosensory … [Read more...]
Florida Man Fined for Blocking Cell Service on the Road
A Florida man reportedly caught using a cell phone jammer during his daily commute is facing a sizable fine for illegal interference. The Federal Communications Commission announced last week it will fine Jason Humphreys of Seffner, Fla. $48,000 for use of a signal jamming device, which work by transmitting signals that overpower, block or interfere with authorized … [Read more...]
Study Finds No Danger from Magnetic Fields in Electric Vehicles
An international study has concluded the electromagnetic radiation produced by the electric motors powering hybrid, plug-in hybrid, all-electric and hydrogen fuel cell cars to be harmless to passengers inside the vehicles. The EU-funded study, led by Norwegian independent research organization SINTEF, looked at the intensity of magnetic fields in seven electric cars, one … [Read more...]
Data Centers Vulnerable to EMPs, Say Experts
Data centers, used to house computer systems and associated components such as telecommunications and data storage systems, store everything from classified government information to personal photos posted on social media websites. Designers must consider a number of key factors when constructing a data center facility, including site selection, mechanical and electrical … [Read more...]
