DESCRIPTION:Many types of cell in our bodies are not static but actively m
 ove around. The effects can be good\, such as when immune cells search and
  destroy invading organisms\, or bad\, such as when cancer cells spread to
  distant parts of the body. Many biochemical circuits are implicated in ce
 ll movement\, but cell fragments with no such circuits also move spontaneo
 usly -- the cellular equivalent of a headless chicken. This observation su
 ggests the presence of an autonomous "motility engine" whose operation is 
 controlled\, but not maintained\, by the complex biochemical circuits pres
 ent in real cells. I shall describe a simplified mathematical model for th
 is engine\, using ideas borrowed from the study of liquid crystalline mate
 rials\, as found in every mobile phone and laptop screen.\n
