Longing to be picking up information after new start (8)
I believe the answer is:
'longing' is the definition.
(I know that longing can be written as yearning)
I can't explain the rest of the clue.
(Other definitions for yearning that I've seen before include "Intense longing" , "Strong desire" , "Feeing great desire" , "Longing - desire" , "Longing, wishing for" .)
