Researchers collaborating on the SOPCAWIND project have developed software to optimize wind farm placement, in order to reduce noise, environmental impact, and telecommunications interference. Wind farms, while a valuable and viable source of energy, reportedly meeting up to 8 percent of Europe’s energy needs, are accompanied by significant drawbacks; namely, noise … [Read more...]
Korean Study Reveals Negative Effects of Terahertz EM-Waves in Living Organisms
In a premiere study on the effects of teraherz waves on living organisms, scientists in Korea have observed heightened skin inflammation in mice exposed to strong terahertz waves, signaling the potentially dangerous side effects of these waves in other living beings, such as humans. Terahertz wavelengths, located between infrared waves and microwaves on the electromagnetic … [Read more...]
Paradoxical Laser System Shuts Off with Energy Boost
Researchers from Princeton University and Vienna University of Technology have demonstrated a laser system that paradoxically turns off, rather than becoming brighter, when more power is added. The system is comprised of two lasers measuring roughly the width of a human hair that are separated by a distance 50 times smaller than the lasers themselves. In the lab, researchers … [Read more...]
Study Highlights Need to Re-Evaluate Railway EMC Standards
As part of a recently-completed European Union study on the effects of multi-source electromagnetic interference on trains, a British consulting company has helped redesign the way that conformance to railway electromagnetic compatibility (EMC) standards is determined. The project in question, a two-year study known as TREND (Test of Rolling Stock Electromagnetic Compatibility … [Read more...]
Sub-Wavelength Images Could Be Made at Radio Frequencies
Scientists have released new theoretical and experimental work that suggests an innovative method using optical wavelengths to overcome certain restrictions on electric field evaluation. Current methods of mapping electric fields at radio frequencies employ certain metallic structures such as dipoles, probes and reference antennas. These structures, however, must be roughly … [Read more...]
Researchers Predict Electrical Resistivity of Metals Under Extreme Pressures
A study recently published in the Proceedings of the National Academy of Sciences (PNAS), headed by scientists at Rensselaer Polytechnic Institute (RPI), has demonstrated how subjecting metals to intense pressures could lower their electrical resistance, which could potentially lead to increased speed and performance in many technologies. Strain engineering, or the … [Read more...]
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...]
Improving Graphene/Polymer Composites for EMI Shielding
Researchers in China have discovered a way of improving how graphene is used in polymer segregated composites for electromagnetic shielding, using a novel in situ thermal reduction technique that maximizes electromagnetic interference shielding effectiveness (EMI SE) while reducing agglomeration. The use of graphene to build up polymer segregated conductive networks in … [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...]
Interference From Magnetic Light Rail Trains Forces UW to Move Labs
Sound Transit and the University of Washington are working out a $43 million deal to move some of the university’s labs across campus, in order to avoid interference caused by an underground light rail tunnel. The lab buildings in question contain very precise and sensitive equipment, such as electron microscopes, that are extremely vulnerable to electromagnetic interference. … [Read more...]
