DESCRIPTION:I will present results from Molecular Dynamics simulations of 
 pure andcrowded lipid bilayer systems\, giving evidence of anomalous diffu
 sion.While in the pure lipid bilayer this anomaly is very short ranged\, t
 headdition of colesterols or the passage to the gel phase leads to exten-d
 ed anomalous diffusion.&nbsp\; The character of the dynamics corresponds t
 othat of the fractional Brownian motion in the dilute bilayer\, changingto
  non-Gaussian motion when the bilayer is crowded with proteins. Realbiolog
 ical membranes show macroscopic anomalous diffusion\, which is ev-idenced 
 from superresolution microscopy experiments. In particular themotion becom
 es non-ergodic and ageing.
