 acci\nAbstract: Sylvia CremerSocial immunity: protecting the colony from d
 iseaseLike any organism\, ants\, termites and other social insects defend 
 themselves against pathogen infection by their individual immune system. I
 n addition\, they protect their colony by “social immunity”\, reached
  by cooperative actions of colony members to reduce the risk of infection 
 and disease transmission. As such\, social insects perform mutual sanitary
  care\, provide infection treatment and modulate the colony’s social int
 eraction network. Importantly\, individual and social immunity closely int
 eract\, as sanitary care often boosters the caregiver’s immune system\, 
 increasing its future disease resistance. Likewise\, different disease sus
 ceptibility affects how individuals perform sanitary care. We study the me
 chanisms of this cooperative disease defence\, its epidemiological consequ
 ences and how it affects the coevolution with their pathogens.László Erd
 ösUniversality phenomena in non-Hermitian random matricesEugene Wigner’
 s fundamental discovery from the 1950’s asserts that the energy level 
  statistics of any sufficiently complex quantum system exhibits a new ty
 pe of universal behaviour\, called the Wigner-Dyson-Mehta universality. M
 ost research in random matrices in the last decades focused on the origina
 l Hermitian version of this paradigm. More recently we initiated a system
 atic study of the analogous questions for non-Hermitian matrices that I w
 ill report on.
