Microwaves

You might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally". But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such …

…prove harmful over the long term. One line of experiments has shown that uncoiled DNA molecules in a test tube can absorb microwave energy. The unravelled DNA chains resonate to the microwaves in the same way that a violin string vibrates when plucked. The question this raises is this: does microwave radiation vibrate coiled DNA in the human body, and if so, is this vibration strong enough to knock off vital molecules from the chain?
