Texto de apoio New Studies Link Cell Phone Radiation with Cancer Researchers call for greater caution, but skeptics say the evidence from rat studies is not convincing By Charles Schmidt Does cell phone radiation cause cancer? New studies show a correlation in lab rats, but the evidence may not resolve ongoing debates over causality or whether any Getty Images effects arise in people.

The ionizing radiation given off by sources such as x-ray machines and the sun boosts cancer risk by shredding molecules in the body. But the nonionizing radio-frequency (RF) radiation that cell phones and other wireless devices emit has just one known biological effect: an ability to heat tissue by exciting its molecules. Still, evidence advanced by the studies shows prolonged exposure to even very low levels of RF radiation, perhaps by mechanisms other than heating that remain unknown, makes rats uniquely prone to a rare tumor called a schwannoma, which affects a type of neuron (or nerve cell) called a Schwann cell.

Technology and its discontents Nuclear bombs can destroy us. Facebook undermines our privacy. Artificial intelligence (AI) and robots can enslave us (or, worse, take our jobs). Synthetic biology and geneediting have humans playing God. Social media make us depressed: we’ve never been so connected yet never so alone.

Those are just a few of the complaints leveled against technology. For most of human history, however, technology was mostly seen as a force for good. More people would live because of technical progress, from refrigeration to vaccination, than perish because of it, despite lethal inventions such as gunpowder.
