A recent paper reported the first study of the gluon structure of nuclei up to atomic number A = 3, using lattice quantum chromodynamics calculations with unphysical large values of the heavy pion mass. Nuclear modification of the gluon momentum fraction quantity defines a gluonic analogue of the EMC effect and is constrained to be less than approximately 10 percent in these nuclei, consistent with expectations from phenomenological quark distributions and the momentum sum rule. The first moment of the gluon transversity structure function in the spin-1 deuteron is found to be non-zero, providing the first indication of gluon contributions to nuclear structure that can not be associated with an individual nucleon.
