Barrel Balloon Research Suggests Electromagnetic Waves Negatively Affect Earth
A NASA-sponsored research team from Dartmouth demonstrated that plasma waves pounding the planet’s radiation belts are responsible for distributing charged particles into the atmosphere. This type of solar activity can fluctuate and disrupt communication systems, GPS satellites, manned space exploration and power grids. The research team frequently studies the Van Allen … [Read more...]
Spellcheck Increases Electromagnetic Fields Emitted during Computer Activity
Electronic fields emitted by computers during use exposes an individuals’ activity, raising issues concerning privacy. Side-channel signals are easily collected by antennas and reveal data through analysis. A group of researchers from the Georgia Institute of Technology have been redesigning hardware and software for the past three years that will prevent electronic fields and … [Read more...]
NASA’s SMAP Instrument Has Largest-Ever Antenna, Resists RF Interference
On Jan. 29, 2015, NASA will launch its Soil Moisture Active Passive (SMAP) instrument into space, where it can accurately measure Earth’s soil moisture levels via a mesh antenna of record-breaking size. The instrument is comprised primarily of a radar, a radiometer, and the largest rotating mesh antenna ever launched into space. Once in action, SMAP will gather data that will … [Read more...]
New Multichannel Ultrasound Platform Offers Customizable Experience
German scientists have developed a multichannel ultrasound platform that can be adapted to fit a variety of different applications. Typically, ultrasound systems – for example, medical sonograms, submarine sonars, and more – are so specialized that they cannot be used outside of their intended purpose. However, in a recent press release from Fraunhofer-Gessellschaft, … [Read more...]
‘Electrosensitives’ Congregate in Wi-Fi Quiet Zone in West Virginia
A national radio quiet zone in Green Bank, West Virginia, limits transmissions to protect a government telescope. This telescope, known as the National Radio Astronomy Observatory's Robert C. Byrd Green Bank Telescope, is the world’s largest fully steerable radio telescope. The telescope can pick up radio waves from space that are weak and difficult to identify. “The Federal … [Read more...]
UK Homeowners Could Face Criminal Prosecution due to EMI
Homeowners in the United Kingdom who use main wiring systems in their homes (power line networking equipment) could face prosecution if their broadband interferes with radio signals. This method of networking has become a clear alternative to Wi-Fi networks. Ofcom, the communications regulator in the UK, has published a new proposal for a regulation that would allow officials … [Read more...]
