29D, 37D and 56A hard to nail to complete.
37D 'Scientist' If my other answers correct have _I_C_E_O_ _ (10)
56A 'Complete eradication' If correct _ _ _ _ R_A_I_N (11)
and 29D 'Show a shift in attitude' If correct looks like CHANGE ONES _L_ _ (6,4,4).
So many other jobs need doing would like to move on!
Thanks both so much. Between you, you helped me get there. Was sure the suggestions Biochemist and Extirpation were correct so realised Photofluorescence had to be wrong. Change Ones Tune sounded right so came up with Photoluminescence and suddenly all solved! Have a good weekend.
