Bacterium counteracts 'coffee ring effect'
Lucky bacteria strike it rich during formation of treatment-resistant colonies
In biology, we often think of natural selection and survival of the fittest. What about survival of the luckiest? Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly ...
