DESCRIPTION:Prof. Stephen Mann\, Bristol University UK\nRecent progress in
  the synthetic construction of micro-compartmentalized colloidal objects c
 omprising integrated biomimetic functions is paving the way towards rudime
 ntary forms of artificial cell-like entities (protocells) for modelling co
 mplex biological systems\, exploring the origin of life\, and advancing fu
 ture proto-living technologies. Although several new types of protocells a
 re currently available\, the design of synthetic protocell communities and
  investigation of their collective properties has received little attentio
 n. In this talk\, I review some recent experiments undertaken in my labora
 tory that demonstrate simple forms of higher-order dynamic behaviour in sy
 nthetic protocells. I will discuss several new areas of investigation: (i)
  enzyme-powered motility and collective migration in buoyant organoclay/DN
 A protocells\, (ii) artificial predatory and phagocytosis behaviour in mix
 ed populations of synthetic protocells\, (iii) chemical coupling and commu
 nication in ordered protocell communities\, and the chemical construction 
 of beating prototissues. I will use these new model systems to discuss pat
 hways towards the advent of proto-living materials.\n \nGeneral Reference
