Biophoton Emission from the Hands
Ultraweak light emission from tissues for all living systems
has been discovered by many researchers in Russia,
Australia, Germany, Poland, Italy, USA, China, and
Japan by using modern photomultiplier techniques.
Even though there is no agreement about the interpretation
of this phenomenon, the hypothesis by Popp offers
a very challenging view.
