What is it about?
Small parasitic bacteria called mycoplasmas can move against fluid flow by using their polar cell shape and asymmetric cell binding. The article uses optical microscopy and a microfluidic chamber to observe the bacteria under different flow conditions.

Why is it important?
The article shows how small bacteria sense and respond to mechanical forces in their native environment. It also provides insights into the role of motility in the pathogenesis of these bacteria, which cause diseases in humans and animals.
