[unable to retrieve full-text content]Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Physicists recently found that these organisms can also survive in the presence of extreme alien light. The findings show that the way in which light is received by the bacteria can dictate the difference between life and death.
