  text: Flows through pipes and channels are the most common means to transport fluids
    in practical applications and equally occur in numerous natural systems. In general,
    the transfer of fluids is energetically far more efficient if the motion is smooth
    and laminar because the friction losses are lower. However, even at moderate velocities
    pipe and channel flows are sensitive to minute disturbances, and in practice most
    flows are turbulent. Investigating the motion and spatial distribution of vortices,
    we uncovered an amplification mechanism that constantly feeds energy from the
    mean shear into turbulent eddies. At intermediate flow rates, a simple control
    mechanism suffices to intercept this energy transfer by reducing inflection points
    in the velocity profile. When activated, an immediate collapse of turbulence is
    observed, and the flow relaminarizes.
