Back in 2006, Henry Lai, a professor emeritus at the University of Washington analyzed all available studies on cell phone radiation from 1990 to 2006. He found that 50% of the 326 studies showed a biological effect from radio-frequency radiation, but when he divided them into independently fu...
Cervix:A donut-like shape with a tiny hole in the middle, it connects your uterus and your vagina. It lets menstrual blood out and sperm in. Your cervix stretches open (dilates) during childbirth. Uterus:This is a pear-shaped muscular organ about the size of a small fist. It's where ...
So maybe have a second cup outside the first one with an air gap (or, better still, a vacuum) in between. That's convection and conduction just about licked, but what about radiation? If you were to wrap aluminum foil round the outer cup, most of the infrared radiation the hot ...

“A phone’s battery is not drained when you use it while charging wirelessly.” If you want to slow down charge cycles, the simplest way is to cut the amount of power you use. A rogue app that’s continually sending data in the background, or an area of poor cell connectivity where...
Because I wanted to avoid excessive radiation from scans (and my oncologist was actually very conservative with his use of CT/ PET scans for his patients with slow-growing cancers like myself,) we chose to use hCG testing as another tool in addition to detailed blood panels and physical exam...
Stressed Out Plastic is Even Worse Realizing that plastics are more likely to leach chemicals when exposed to various stressors like heat or light, the researchers also tested the products after subjecting them to UV radiation (mimicking the effect of sunlight), wet heat (as in a d...
The measurement room is an anechoic chamber that is usually used to determine radiation characteristics of high-frequency antennas. The room is not a complete Faraday Cage, and, as described below, the door to the room was kept ajar during the experiment. The walls, floor and the ceiling are...
In these products, the phosphor is mixed with a radioactive element, and the radioactive emissions (see How Nuclear Radiation Works) energize the phosphor continuously. In the past, the radioactive element was radium, which has a half-life of 1600 years. Today, most glowing watches use a ...
