SUMMARY:Eukaryotic chemotaxis - how amoebae use non-equilibrium physics to
  figure out where to go - Professor Herbert Levine\, Department of Physics
 \, University of California San Diego\, California

CONTACT:Duncan Simpson
DESCRIPTION:Many types of eukaryotic cells are able to detect chemical gra
 dients and move accordingly. Unlike the case for bacteria\, these cells ar
 e large enough for the gradient detection to rely on differential receptor
  binding probabilities on the cell membrane. It is not yet understood how 
 this noisy input data is processed by the cell to make the motion decision
 \; thus we cannot a priori predict the detection threshold\, the response 
 kinetics and the plasticity to changing stimuli. This talk will focus on s
 ome recent nonlinear models of this cellular information processing system
  and on experiments in progress on the amoeba Dictyostelium discoideum to 
 test some of the resulting expectations.\n
