  Nuclear clusters or voids in the inner crust of neutron stars were predicted
to have various shapes collectively nicknamed nuclear pasta. The recent review
in Ref. \cite{Lopez1} by L\'opez, Dorso and Frank summarized their systematic
investigations into properties especially the morphological and thermodynamical
phase transitions of the nuclear pasta within a Classical Molecular Dynamics
model, providing further stimuli to find more observational evidences of the
predicted nuclear pasta in neutron stars.
