By Mark Buchanan A COMPUTER model of the battles between bacterial colonies could lead to salamis that are safer to eat and have longer shelf lives. The model could also help food scientists devise new ways to tackle the growth of dangerous bacteria in food. The bacterium Listeria monocytogenes is a leading source of food-borne disease in meats and other products. To understand how it grows in food, scientists often turn to computer models which describe how bacteria reproduce given a source of food and variables such as temperature, pH and humidity. Unfortunately,
