Last week’s puzzle featured what a solver informed me are called letter banks. The way that works is you have a long word with repeated letters, all of which are found in a shorter word (the “bank”) which does not have any repeated letters. So our five theme entries could be reduced down to the following letter banks:
NONRECURRENT -> COUNTER (or recount or trounce)
CAPITALISTIC -> PLASTIC
INCONSISTENCIES -> NOTICES (or section or noetics)
ANTIAIRCRAFT -> FRANTIC (or infarct or infract)
NONPERTINENT -> POINTER (or protein or repoint)
Next thing to notice was that the letter banks were themselves used as clues for other grid entries (and in a few cases the clue was a bit forced):
71a. Counter = RESIST
68a. Plastic (as in “fake”) = ERSATZ
50a. Notices (as in “bits of news”) = ITEMS
18a. Frantic = GO-GO
14a. Pointer = NEEDLE

The first letters of those grid entries (in order of associated theme entry, not grid order) spell out REIGN, itself a promising letter bank. And indeed if you reverse the process you can find, using only those five letters, an 11-letter scientific discipline as the prompt requested – it’s ENGINEERING.
Up next is puzzle #71, “Texas Hold ‘Em.” ***Update*** – I was in a hurry this morning and left a clue unfinished; corrected version below.
