Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different ...

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher ...

In the classic “run-and-tumble” movement pattern, bacteria swim forward (“run”) in one direction and then stop to rotate and reorient themselves in a new direction (“tumble”). During experiments where ...
