For an active particle to be able to swim in a low-Reynolds number flow, breaking of time-reversal symmetry and centrosymmetry is required. Typically, this is achieved through asymmetric characteristics of the swimmer. Now, swimming of centrosymmetric pulsating bubbles in an anisotropic fluid is reported.
