  We review the current literature on the formation of Coherent Structures
(CoSs) in strongly turbulent 3D magnetized plasmas. CoSs (Current Sheets (CS),
magnetic filaments, large amplitude magnetic disturbances, vortices, and
shocklets) appear intermittently inside a turbulent plasma and are collectively
the locus of magnetic energy transfer (dissipation) into particle kinetic
energy, leading to heating and/or acceleration of the latter. CoSs and
especially CSs are also evolving and fragmenting, becoming locally the source
of new clusters of CoSs. Strong turbulence can be generated by the nonlinear
coupling of large amplitude unstable plasma modes, by the explosive
reorganization of large scale magnetic fields, or by the fragmentation of CoSs.
A small fraction of CSs inside a strongly turbulent plasma will end up
reconnecting. Magnetic Reconnection (MR) is one of the potential forms of
energy dissipation of a turbulent plasma. Analysing the evolution of CSs and MR
in isolation from the surrounding CoSs and plasma flows may be convenient for
2D numerical studies, but it is far from a realistic modeling of 3D
astrophysical, space and laboratory environments, where strong turbulence can
be exited, as e.g. in the solar wind, the solar atmosphere, solar flares and
Coronal Mass Ejections (CMEs), large scale space and astrophysical shocks, the
magnetosheath, the magnetotail, astrophysical jets, Edge Localized Modes (ELMs)
in confined laboratory plasmas (TOKAMAKS), etc.
