What is it about?
Pulsed magnetic fields (PEMF) have been used in medicine and healing for over 50 years, to treat conditions like bone fractures, inflammation, and chronic pain. However, the signals used were highly complex and no one really understood what feature (frequency, amplitude, etc.) was important for the health effects. In this paper, this mystery is addressed by showing that cells respond to small decrease in the earth's geomagnetic fields by producing ROS, which induces the health benefits. We conclude that the signals used for PEMFS can be considerable simplified to yield more predictable effects at lesser cost and greater effectiveness.

Why is it important?
PEMF therapy on the ;market has great potential. It can treat many serious conditions where no other therapy is effective (eg chronic pain), safely and without side effects. Our work hugely simplifies the design and implementation of the treatment compared to existing devices on the market. Also the way we study them, using a simple cell culture coupled with a simplified exposure system, can be used to even further improve the benefit.
