DESCRIPTION:Active nematic systems display turbulent-like motion when unco
 nstrained. While this chaotic motion can be controlled in space by geometr
 ic confinement\, achieving temporal control remains an open challenge. I w
 ill consider the dynamics of an active nematic confined in a channel made 
 of viscoelastic material. For soft channels\, the system produces spontane
 ous oscillations with periodic flow reversals. Notably\, the temporal freq
 uency of the oscillations can be manipulated by altering the mechanical pr
 operties of the surroundings\, offering a guiding principle to control the
  dynamical behavior of active materials.\n&nbsp\;\nReference: PRE 108\, 06
