  The new observational data on interstellar dust, obtained during the past few
years, in particular, revised ISM elemental abundances, the polarization curve
from the far UV to the near IR, spectra of dust infrared emission, extended red
emission (ERE), are in serious conflict with existing dust models. We proposed
here to use the regularization approach as a base for developing a modern dust
model, which attempts to self-consistently explain most of the available
observational data.
