Research by scientists into why some bacteria have different shapes has found that a curved shape can make it easier to find food. Computer simulations were used to compare the swimming of differently shaped bacteria. Results showed that a curved shape can be beneficial for efficient swimming and for finding food through the use of chemical trails (known as chemotaxis) – but at the expense of higher cell construction costs.
