Field near a TNT molecule. Click to enlargeWith the ongoing debate about potential health hazards of living near radio/TV towers, or the dangers of extensive cell-phone use, it is reassuring to see the latest news on the efficacy of electric fields in slowing down some cancers. (Of course a skeptic might claim that the news is a spin job by cell operators to get activists from fighting the placement of towers and cell sites near population centers.)
Nevertheless, the study is intriguing because it describes a set of potential reasons why the E-fields might be the causal agent for the stunted cancer growth.
In vitro, the electric fields were seen to have two effects on the tumor cells.
First, they slowed down cell division. Cells that ordinarily took less than an hour to divide were still not completely divided after three hours of exposure to an electrical field of 200 kHz...
