Researchers exposed microscopic worms (C. elegans) to weak microwave radiation at frequencies similar to cell phones and found that the radiation actually increased growth rates by 8-11% and improved reproductive success by 28-40%. Importantly, when the researchers heated the worms to the same temperature that microwaves would cause, they saw the opposite effects, proving that microwaves cause biological changes through mechanisms beyond simple heating.
