Israeli scientists communicate with plants

Tuesday, July 08, 2008 |  Israel Today Staff

Israeli scientists at Bar-Ilan University have developed a method of communicating directly with plant life in order to determine levels of contamination in bodies of water.

The technological breakthrough has already won international acclaim, and has been published in many of the most prestigious scientific journals, reported The Jerusalem Post.

Departing from traditional methods of measuring contamination in plant life, the Israelis decided to find a way to let the plants literally tell them how they are doing.

By shining a laser beam on small algae plants, the scientists induce photosynthesis (the process of converting light into energy). The light that is not converted into energy is converted into sound waves that heat the surrounding water. By listening to those sound waves the Israelis are able to determine if the plant is healthy or contaminated.
