DESCRIPTION:Biomolecular condensates are membraneless organelles ubiquitou
 s across cell biology. Chemical reactions have been proposed as a non-equi
 librium mechanism to stabilise the size of condensates. At the same time\,
  active field theories (in particular "Active Model B+") also predict the 
 formation of stable size-limited microphases. However\, an explicit connec
 tion between these two systems has been lacking. I will present rigorous r
 esults showing how pattern-forming reaction-diffusion systems with conserv
 ation laws universally reduce to an extended form of "Active Model B+" at 
 long times. These results provide a direct link between reaction-diffusion
  systems and active matter.\nThe work I will present is from a collaborati
 on with Thomas Speck (Stuttgart) and Thomas Machon (Bristol):\nhttps://arx
