"Mortal Oscillatory Rates (MOR) are the frequencies that Royal R. Rife proposed would allow a user of his Rife machines to kill the specific micro-organisms responsible for disease in their host."

"A new study by researchers in MIT’s Department of Mechanical Engineering suggests that coronaviruses may be vulnerable to ultrasound vibrations, within the frequencies used in medical diagnostic imaging."

“If I added one additional frequency, in a special relationship to the first frequency, I’d be creating more power and have a better chance at landing on the frequency necessary to change the organism,” Dr. Holland says. “When I added the eleventh harmonic, I looked through the microscope and discovered that the microorganism had shattered. It reminded me of how a crystal glass shatters when a soprano hits just the right note.”

"These treatments would presumably be safer for patients than many antiviral drugs that can have terrible side-effects. Normal cells should not be affected by the virus-killing lasers or sound waves because they have resonant frequencies much lower than those of viruses, Sankey said.
Moreover, it is unlikely that viruses will develop resistance to mechanical shaking, as they do to drugs."
