<b><u>Abstract</u></b>: In this talk we revisit so-called target mass corrections (TMCs) to nuclear structure functions in lepton-nucleus deeply inelastic scattering (DIS), which account for the fact that the masses of target hadrons are not guaranteed to be
small compared to momentum transfers in DIS. Starting from a qualitative picture of TMCs intended for a broad audience, we then move onto more technical details of their derivation for arbitrary nuclei, and finish with various numerical results (cross sections,
ratios of cross section, etc.). We find that nuclei, like protons, can formally be expressed directly in terms of partonic degrees of freedom (quarks and gluons), and that intermediate pictures of "bound nucleons", while useful, are not formally necessary.
We also show that TMCs for nuclei can be expressed in a way that is universal for all nuclei and readily approximated in numerical codes.<br>
