Some land for current research (5)
I believe the answer is:
acres
'some land' is the definition.
(acres measure land)
'current research' is the wordplay.
'current' becomes 'ac' (alternating current).
'research' becomes 'res' (academic abbreviation).
'ac'+'res'='ACRES'
'for' acts as a link.
(Other definitions for acres that I've seen before include "fields?" , "may burden landed folk" , "Cares about the tracts of land" , "large area of land" , "Scare (anag)" .)
