    "abstract": "A brief review is given of the progress in studying the long-lived filaments\n(LLFs) in fusion plasmas (tokamaks, Z-pinch, plasma focus). The paper reports\non (i) resolving the fine structure of LLFs, and (ii) verification of our\nhypothesis (1998) which suggested the LLFs to possess a microsolid skeleton.\nThe recent proof-of-concept studies showed the presence of tubular and\ncartwheel-like structures in (i) various dust deposits in tokamak T-10, in the\nrange 10 nm - 10 mcm, and (ii) visible light images of plasma, in the range 100\nmcm - 10 cm, at initial stage of discharge (e.g., before appearance of\ndischarge electric current) in tokamak, plasma focus and vacuum spark. The\ntopological similarity of the above structures (especially, \"cartwheels\") and\nthe observed trend of assembling bigger tubules from smaller ones (i.e. the\nself-similarity) allow to draw a bridge between the microdust skeletons in the\ndust deposits and the centimeter scale LLFs in fusion plasmas.",
