Latest news at university: daughter had some food (6)
I believe the answer is:
update
'latest news' is the definition.
(I've seen this before)
'at university daughter had some food' is the wordplay.
'at university' becomes 'up' ('up' can mean studying at university).
'daughter' becomes 'd' (genealogical abbreviation).
'had some food' becomes 'ate' (to eat is to have food).
'up'+'d'+'ate'='UPDATE'
(Other definitions for update that I've seen before include "Latest news" , "Make more modern" , "Correct - modernise" , "Supply latest info" , "Renew" .)
