This discovery is a surprising twist for cell researchers. Scientists don't know what causes these incredibly strong fields or why they' are there. But now using new nanotools, such as voltage-sensitive dyes, they can start to measure them at least. Researchers believe they may be able to learn more about disease states, such as cancer, by studying these minute, but powerful electric fields.

Great clip. Bloody amazing stuff these researchers get up to. If we can just prevent us exterminating ourselves, we may really prosper as a race.
