Active flows solve sudoku-like problems

A normal viscous fluid can be set in motion only by a difference in pressure: squeeze one end of a straw and the fluid inside will move instantly to a lower-pressure region. Research on active fluids in networks is dominated largely by theory and numerical simulations, sojorge and co-workers' e...

Description
Summary:A normal viscous fluid can be set in motion only by a difference in pressure: squeeze one end of a straw and the fluid inside will move instantly to a lower-pressure region. Research on active fluids in networks is dominated largely by theory and numerical simulations, sojorge and co-workers' experiments are an exciting addition to the field. Jorge and colleagues' mechanistic insight into how non-local interactions emerge in active systems might also guide research into the motility of living cells and organisms in complex environments.
