 rected  flows  of  spin  angular  momentum  –  are  a fascinating manife
 station of spin physics in the solid state. Pure spin currents can propaga
 te not  only in metals and semiconductors\, but also in magnetically order
 ed insulators. This makes a whole  new set of materials and material combi
 nations interesting for spin transport experiments and  spin-electronic de
 vices. Moreover\, in the last decade\, robust experimental schemes for the
   generation and/or detection of pure spin currents have been established\
 , sparking intense research  activities. In ferromagnet/normal metal thin 
 film heterostructures for example\, pure spin currents  can be generated b
 y means of spin pumping [1\,2]\, or via the application of thermal gradien
 ts in the  so-called spin Seebeck effect [3\,4]. An elegant concept for de
 tecting spin currents relies on the  inverse spin Hall effect: Because of 
 spin-orbit coupling\, a pure spin current induces a charge  current\, whic
 h can be measured using conventional electronics [2\,3\,4]. The interplay 
 between spin  and charge transport furthermore gives rise to the so-called
  spin Hall magnetoresistance (SMR)  effect [5]\, and allows for the electr
 ical quantification of magnon diffusion lengths in magnetic  insulator/nor
 mal metal nanostructures [6\,7]. In the talk\, I will give an introduction
  to pure spin  current transport and spin Hall physics\, and then address 
 recent highlights as well as interesting  perspectives for pure spin curre
 nt based experiments and spin current circuits.  References [1] Y. Tserkov
