Latest news is brief (6)
I believe the answer is:
update
I believe this is a double definition.
'latest news' is the first definition.
(I've seen this before)
'brief' is the second definition.
(I've seen this before)
'is' acts as a link.
(Other definitions for update that I've seen before include "Bring to present status, say accounts" , "Latest news" , "change of status" , "Make more modern" , "Bring to the latest state, records say" .)
