Subatomic particle from Turin one gathered (8)
I believe the answer is:
neutrino
'subatomic particle' is the definition.
(neutrino is a kind of subatomic particle)
'turin one gathered' is the wordplay.
'gathered' indicates an anagram.
'turin'+'one'='turinone'
'turinone' is an anagram of 'NEUTRINO'.
'from' is the link.
(Other definitions for neutrino that I've seen before include "Subatomic particle, now said to travel faster than light" , "There's almost nothing to it!" , "Minute item lacking mass" , "Uncharged elementary particle" , "Spinner" .)
