Cellphones Do Not Cause Brain Cancer, Says 29-Year Study (gizmodo.com)

A study from Australia reassures us that cellphones are reasonably safe, and do not cause brain cancer. Chris Mills writes from Gizmodo: "The study examines the incidence of brain cancer in the Australian population between 1982 to 2013. The study pitted the prevalence of mobile phones among the population -- starting at 0 percent -- against brain cancer rates, using data from national cancer registration data. The results showed a very slight increase in brain cancer rates among males, but a stable level among females. There were significant increases in over -70s, but began in 1982, before cellphones were even a thing." What makes the study in Australia so authentic compared to other studies conducted in other countries is the fact that all diagnosed cases of cancer have to be registered by law.

    Erm, no, your whole thinking is completely off. For one thing, all alcohol that you're likely to have on hand has water in it (If not from the original solution it came in, at least from absorbing it from the atmosphere). Second, not *only* water is heated, many other molecules respond too (including alcohol, since it also has a dipole moment, 1.66, which is actualy pretty close to that of water, 1.87). Just look it up on wikipedia for FSM's sake: https://en.wikipedia.org/wiki/Microwave_oven#Principles

    Many molecules (such as those of water) are electric dipoles, meaning that they have a partial positive charge at one end and a partial negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field of the microwaves. Rotating molecules hit other molecules and put them into motion, thus dispersing energy. This energy, when dispersed as molecular vibration in solids and liquids (i.e. as both potential energy and kinetic energy of atoms), is heat.
