In an article published in Physical Review Letters, Bristol scientists have answered the fundamental question: "Is it possible to move without exerting force on the environment?", by describing the tractionless self-propulsion of active matter. Understanding how cells move autonomously is a fundamental question for both biologists and physicists.

Advanced simulations have solved a problem in turbulent fluid flow that could lead to more efficient turbines and engines. When a fluid, such as water or air, flows fast enough, it will experience turbulence - seemingly random changes in velocity and pressure within the fluid. From my first days studying fluid mechanics I had some fundamental questions that I wanted to know the answers to.
