Electromagnetic Fields and Biological Effects

Electromagnetic fields (EMFs) generated by power lines, mobile phones, and other technologies interact with living tissue in ways that researchers are still working to characterize at the molecular level. Central questions include whether radiofrequency exposure damages DNA or elevates cancer risk, and how biological systems like the cryptochrome protein may exploit weak magnetic fields for processes such as magnetoreception in animals. The evidence so far is often contested, partly because the effects under study are subtle, dose-dependent, and difficult to isolate from confounding factors in both laboratory and epidemiological settings. Active work is clarifying the biophysical mechanisms involved, refining safety guidelines, and determining whether chronic low-level exposure carries meaningful long-term health consequences.
