Can you hear me now? For years, it has been popular doctrine that cell phone use is bad for our brains, but we glue our phones to our ears anyway. Cell phones emit radio frequency-modulated electromagnetic fields (RF-EMFs) that are questioned for their potential danger when the brain is exposed to them. The oscillatory frequencies of RF-EMFs correspond to those measured in neural tissue, and thus could interfere with neural activity. The amount of electromagnetic radiation given off by our communication devices is small, but is radiation all the same. Radiation exposure is dangerous for any kind of cell in our body, and can penetrate cells and damage DNA either by crashing into the molecule directly or causing damage indirectly by forming free radicals from water that can have cancer-causing effects.
For those of you who’ve forgotten or perhaps even repressed your memories of high school English class, the line in the title is the cry of the power-hungry and all-around homicidal maniac Lady Macbeth, the female lead in Shakespeare’s great tragedy, Macbeth. After having committed regicide so that her husband may become king, she becomes convinced that she cannot wash King Duncan’s blood from her hands. Thoughts are soliloquized, guilt is manifested in madness, and archetypes are born.
