K2 Summit camera and Quantum energy filter highlight the many forms of the MAC array also known as the bacterial death star

Metamorphosis-associated contractile (MAC) structures show a surprising variety of uses in bacteria. Shown above is one particular structure which has been identified to be used in bacterial warfare. Data was collected using a GIF Quantum^® energy filter with a K2 Summit^® camera and is described by Shikuma et. al., in a recent issue of science.
