Effects of radio waves on male fertility
In recent years, male fertility has changed due to the effects of environmental, health and lifestyle factors and the infertility rate has increased, to the extent that male fertility may be affected by extreme heat, exposure to pesticides, radiation, substances Changes in radioactivity, lifestyle, stress and occupation. In the environment, there are ionizing and non-ionizing rays whose effect...
متن کاملMAPK activation by radio waves.
In this issue of the Biochemical Journal, Freidman et al. report the findings of a study to look at the potential of mobile phones to activate intracellular signalling cascades. They found that radio waves corresponding to the frequency commonly used by mobile phones are able to activate ERK1/2 (extracellular-signal-regulated kinases 1 and 2). This effect was observed even at intensities lower ...
متن کاملManipulating light waves: introduction.
This special Applied Optics issue pays tribute to an extraordinary teacher, scientist, and friend who revolutionized several fields of optics, such as holography, microscopy, and biomedical imaging, by contributing his unique and simplified perspective on complicated phenomena. We thank all the authors who have contributed papers to this special feature as a manifestation of the long and unique...
متن کاملTwisted Radio Waves and Twisted Thermodynamics
We present and analyze a gedanken experiment and show that the assumption that an antenna operating at a single frequency can transmit more than two independent information channels to the far field violates the Second Law of Thermodynamics. Transmission of a large number of channels, each associated with an angular momenta 'twisted wave' mode, to the far field in free space is therefore not po...
