Resonance is a well-known principle in physics.  If a tuning fork designed to produce a frequency of 400 Hz is struck, causing it to oscillate and then brought into the vicinity of another 400 Hz tuning fork; the second tuning fork will begin to oscillate at the same frequency.  The first tuning fork is said to have entrained the second one, causing it to resonate.

Resonance naturally occurs whenever two objects vibrate at the same frequency.  In its essence, resonance is the process of wireless energy transfer from a vibrating object to a relatively still object, which enables the still object to receive energy and consequently starts oscillating at the same frequency.

The same principle applies to biological matter when the phenomenon is referred to as Bioresonance.

Electromagnetic force can shift between a magnetic state and electricity.  A moving electrical charge induces a magnetic field while a moving magnetic field creates electricity in any electroconductive surface bounded by that path.

Each bacterium or virus has its own unique resonant frequency.  The earliest pathologic interaction with healthy cells may be evident as a distortion of harmonious natural cellular signal.

Cells are biological electrical circuits, which may both conduct and process incoming vibrational stimuli and return to a state of balance with Bioresonance. Cells are equipped to respond to any energetic stimuli, be it electrical signals, magnetic fields, electromagnetic fields, heat, light or acoustic resonance.

It is now widely accepted that DNA molecules emit photons of light, the phenomenon known as biophotons emission.  They emit photons at regular intervals, in coherence strong enough to be compared to an ultra-weak laser.
