Thermal effects.
2008-06-06 06:50:00 Microscope photographs of lenses incubated in organ culture conditions for 12 days. Right frame shows Control lens with no damage. Bottom frame demonstrates the effect of microwave radiation on bovine lens sutures for a total exposure of 192 cycles (1.1 GHz, 2.22 mW). Each cycle lasts 50 min followed by 10 min pause. In the absence of microwave radiation, the bubbles are generated by temperature increase to 39.5 °C during 4 h; see left frame. Credit: IsraCast Technology News One well-understood effect of microwave radiation is dielectric heating, in which any dielectric material (such as living tissue) is heated by rotations of polar molecules induced by the electromagnetic field. In the case of a person using a cell phone, most of the heating effect will occur at the surface of the head, causing its temperature to increase by a fraction of a degree. In this case, the level of temperature increase is an order of magnitude less than that obtained during the exposure of the hea...

Non-thermal effects.
2008-06-05 06:53:00 The communications protocols used by mobile phones often result in low-frequency pulsing of the carrier signal. Whether these modulations have biological significance has been subject to debate Some researchers have argued that so-called "non-thermal effects" could be reinterpreted as a normal cellular response to an increase in temperature. The German biophysicist Roland Glaser, has argued that there are several thermoreceptor molecules in cells, and that they activate a cascade of second and third messenger systems, gene expression mechanisms and production of heat shock proteins in order to defend the cell against metabolic cell stress caused by heat. The increases in temperature that cause these changes are too small to be detected by studies such as REFLEX, which base their whole argument on the apparent stability of thermal equilibrium in their cell cultures.

2008-05-28 07:00:00 "Flir Systems Inc. (http://finance.aol.com/quotes/-flir-systems-inc/flir/nas) (NASDAQ: FLIR (http://finance.aol.com/quotes/-flir-systems-inc/flir/nas)) provides thermal-imaging and infrared camera equipment for military, law enforcement, and commercial applications," notes Leo Fasciocco (http://www.thestockadvisors.co-m/ccount/click.php?id=2052). In his Ticker Tape Digest (http://www.thestockadvisors.co-m/ccount/click.php?id=2052), which focuses on stocks showing technical breakouts, he explains, "FLIR has convincingly broken out from a five-week base, boosted by the win of a $359 million contract from the Army.""FLIR, with annual revenues of $855 million, has been a sensational winner since 2001. It is a beneficiary of the war on terror and the need for equipment to combat it via military and security needs. "Short-term, the daily chart shows the stock crossing its resistance line at 35.54. The move sends the stock over not only near-term resistance but also over the peak made back in...
