Scientist report that they have developed a new form of light. Whereas ordinary light consists of photons, the new light is made up of phentons. Humans are unable to distinguish phenton from photon light. However, phenton light accelerates plant growth. According to Dr. Mao Frieder of Caltech, bamboo exposed to phenton light grows one inch every two minutes, a growth rate visible to the human eye.
