"Until now, regulations designed to protect people from microwave radiation - from mobile phones, microwave ovens and radar systems - have been based purely on avoiding heating from the microwave radiation."

"The safety of mobile phones is under fresh scrutiny following the discovery that their emissions have an unexpected effect on living creatures. The finding throws out the strongest challenge yet to the widely held belief that heating from mobile phone signals is their only potential threat to brain cells."

This is rather serious considering how wireless devices are about to proliferate - and non-heating based research could take many years to show up any dangers to humans. I wouldn't be surprised if this could also affect DNA/evolution.
