Query: Recent results on hadron form factors   We discuss the recent data on the electric proton form factor, obtained at
JLab, which show a spectacular deviation from the commonly assumed dipole
behavior. We discuss the implication of these results on the deuteron structure
and on the neutron electric form factor: at relatively large $Q^2$ a revision
of the deuteron models may be required, and the neutron electric form factor
might become even larger than the proton electric form factor.
