There are imperial research stations mentioned in Warhammer 40k. do some of them do actual research, or at least there is some grey eminence behind it that can get some results from it, and are there some technical results of their santioned research given to imperial military forces like Imperial Guard/Astra Militarum ?

Are there any forge worlds which look with disgust on those from adeptus mechanicus who think they should rebel against imperium to being back independent mechanicum or are at least opposite to the idea of disloyalty to imperium as whole ?
