Real science: Plants perform molecular maths!

From an article of this title by Heidi Ledford in Nature, 24 June 2013:

"Computer-generated models published in the journal eLife illustrate how plants might use molecular mathematics to regulate the rate at which they devour starch reserves to provide energy throughout the night, when energy from the Sun is off the menu. If so, the authors say, it would be the first example of arithmetic division in biology."
