Query: New constraints on the Yukawa-type corrections to Newtonian gravity at
  short separations   We discuss the strongest constraints on the Yukawa-type corrections to
Newton's gravitational law within a submicrometer interaction range following
from measurements of the Casimir force. In this connection the complicated
problems arising when comparing the measurement data with the Lifshitz theory
are analyzed. Special attention is paid to the results of two recent
experiments on measuring the Casimir interaction between ferromagnetic surfaces
and sinusoidally corrugated surfaces at various angles between corrugations.
