Magnetic Fields in Electric and Hybrid Cars Involve No Threat: Cars under Safety Margin

May 7, 2014May 16, 2014 Pooja Kashyap

Majority welcomed the vehicular era when electric and hybrid automobiles took to the center stage. While there were still others who were doubtful regarding the dangers that might affect the passengers including drivers imposed by the possibly generated electromagnetic fields. However, the increasing number of electric car ownership has thwarted this idea. Seven various electric cars, including hydrogen, gasoline and diesel powered cars, were put under survey by SINTEF, Norway and they discovered that exposure of the electromagnetic radiation was less than 20%. A limit, which was suggested by ICNIRP,…

Propagating Light Revealed New Fundamental Physical Features: Evanescent Electromagnetism

April 28, 2014 Pooja Kashyap

Dynamical properties of light have been consistent and very well accepted ‘fact’ amongst the academia of physics since more than a century. The same conviction has also helped in the understanding of electromagnetic radiation, which suggests that a quantum of light carries momentum in the direction of propagation and secondly a spinning or gyrating effect around the propagation axis. These two characteristics have become the basic tenets of daily occurrences and experimental interactions between light and matter. However, a new form of light called the evanescent waves has emerged having…

Newly Discovered Neighbor of the Sun: Chilly as the Earth’s North Pole

April 27, 2014May 3, 2014 Pooja Kashyap

Kevin Luhman, an astronomer at Penn State University has discovered a star, “brown dwarf” that is around 7.2 light-years away. Currently it appears to be as cold as Earth’s North Pole and positioned at fourth rank with respect to the Sun. The space scientist claims that insights from the new system might helpful in knowing the atmospheres associated with cold temperatures on similar other systems. Like stars, the brown dwarfs initiate the same life cycle but during the collapse, they lack the mass that is required to burn the nuclear…

Fabrication of Bi-Layer Molecular Electronic Devices: Nanoscale Circuitry

April 22, 2014 Pooja Kashyap

Until now, it was difficult to charge particles at molecular scale and hence developing circuits at microscopic level has always presented a huge challenge. However, Alexander Shestopalov from University of Rochester has crossed the huddle making a step closer to the fabrication of microscopically small circuit. He powered an organic light-emitting diode (OLED) with a nanoscale circuitry in where he coupled the positive and negative electrodes with one-molecule thin sheet of organic material. Experimental trials and errors have proved that it’s impossible to control current passing through such a single…

10 Weird Facts about Spiders: The Creepy Crawlers

April 21, 2014April 21, 2014 Pooja Kashyap

Spiders are famous for their architectural skill that is displayed by weaving of web. Majority in the species prefer solitary life, alone in their cobwebs. They look eerie no doubts but they show such unique and weird characteristics that researchers across the globe are still trying to figure out the reasons behind these awestruck potentialities that these arachnids exhibit. Some of them are described below: 1) Bulky DNA The DNA of one spider egg is equal to the amount of genetic material of four humans combined. 2) Immortals There is…

X-Ray Triggered Nanoparticle Photosensitizer: Photodynamic Therapy

April 19, 2014April 18, 2014 Pooja Kashyap

While working upon new security-related radiation detection, researchers at the University of Texas, Arlington discovered an advance in photodynamic cancer therapy. Wei Chen, professor of physics at the UT Arlington, noticed an odd luminescence emitted by copper-cysteamine (Cu-Cy) nanoparticles when while working on an experiment where he was exposing the nanoparticles to X-rays. Upon further investigation, he found out that the luminescence was the byproduct of lost energy that the particles were diffusing. The same byproduct is also utilized in photodynamic cancer therapy to destroy cancer cells.
