NEW YORK, Nov. 4, 2011 /PRNewswire/ -- Wanderport Corp. (OTC Markets-PINKSHEETS: WDRP) announced today the multi-cavity microwave heating unit (MCMHU) was displayed during the company's recent informal gathering held on October 25th, 2011 in Burlington, Vermont, USA. The "meet and greet" was attended by interested individuals having accepted Wanderport's invitation announced in the company's news release of October 17, 2011. All those on hand benefited from a concise power point arrangement...
Berkeley Lab scientists and colleagues will create an advanced extreme-ultraviolet microscope Moore’s Law, hardly a law but undeniably a persistent trend, says that every year and a half, the number of transistors that fit on a chip roughly doubles. It’s why electronics – from smart phones to flat screens, from MP4 players to movie cameras, from tablets to supercomputers – grow ever more varied, powerful, and compact, but also ever less expensive. Whether the trend can continue...
As the realization that radiation emitted by the sun can give rise to skin cancer has increased, so also has the use of sunscreen creams. These creams, however, can give rise to contact allergy when exposed to the sun, and this has led to an increasing incidence of skin allergy. Scientists at the University of Gothenburg and Chalmers University of Technology are leading the hunt for a natural UV filter that does not have undesired effects. "Unfortunately, several of the chemical UV filters...
A new study, published in the Proceedings of the National Academy of Sciences suggests that exposure to ultraviolet (UV) rays in the morning hours may be less harmful than the sun’s ray’s in the afternoon. The study, performed on mice because they have a similar circadian rhythm to humans only opposite, found that mice exposed to UV radiation at 4 am had a 500 percent increase in the incidence of skin cancer than those exposed to UV radiation at 4pm. Since the 24 hour biological...
Recent breakthroughs have enabled scientists from the Northwestern University’s Center for Quantum Devices to build cameras that can see more than one optical waveband or “color” in the dark. The semiconducting material used in the cameras – called type-II superlattices – can be tuned to absorb a wide range of infrared wavelengths, and now, a number of distinct infrared bands at the same time. The idea of capturing light simultaneously at different wavelengths isn’t new....
Researchers said on Monday that measuring radiation exposure using current Federal Communication Commission (FCC) guidelines understates how much radiation most people receive from their mobile devices. The researchers said one reason why is that the current assessment method bases evaluations of how much radiation people are exposed to from their phones on measurements taken using a large, liquid-filled plastic model of the adult human head. The authors of the study published in the...
The benefits of far infrared saunas are becoming known across the country. However, complaints LuxSauna personnel continuously hear from users of other saunas include how the far infrared sauna they purchased just isn’t making them sweat, or they’re not heating up fast enough. Denver, Colorado (PRWEB) October 14, 2011 LuxSauna reviews explain the benefit of thinking twice when reading marketing hype. There is a significant amount of marketing hype and Mocked up studies by...
A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells. In 1999, Ahmed Zewail was awarded the nobel prize in chemistry for his studies of chemical reactions using ultrashort laser pulses. Zewail was able to watch the motion of atoms and thus visualize transition states on...
News About Planet-Threatening Events Space is a violent place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they’d give off colossal blasts of lethal gamma-rays, X-rays and cosmic rays and it’s perfectly reasonable to expect Earth to be bathed in them. A new study of such events has yielded some new information about the potential effects of what are called “short-hard” interstellar radiation events. Several studies in the past have...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
