Just looked through a list of 8 letter branches of science in my Chambers Crossword Dictionary but can't see anything which would make sense of the clue. Do you have any letters please?
Since you obviously don't like my answer splott , presumably you know something that I/we dont. If you have any letters already in place then please share them with us so we don't waste our time thinking of impossible answers.

I did like your answer and used it. I am not yet completely
familiar with Answerbank and doubtless I failed to respond
correctly. Thank you very much for your help.
