What wonderful news on the medical front! Thank you so much for sharing! Indeed, at bottom, everything we perceive to be material is a manifestation of a wave function - a harmony as Markofhumanfeet suggested.
In Physics lingo this is called wave particle duality. Everything we perceive to be material in this four dimensional existence is a manifestation of the fields: electromagnetic, gravity, strong and weak atomic. Or as Einstein said:
"Reality is an illusion, albeit a very persistent one."
So I am thrilled but not surprised that medical research has found healing properties in sound waves.
Beams cut need for cancer surgery
Cancer cells can be selectively targeted
Scientists are perfecting a 'virtual scalpel' which uses ultrasound beams to kill cancer cells without the need for surgery.
Unlike radiotherapy and drugs, the technique also leaves healthy tissue next to a tumour undamaged.
