  I compare the non-relativistic effective theory of one-body dark
matter-nucleon interactions to current dark matter direct detection experiments
and neutrino telescope observations, presenting exclusion limits on the
coupling constants of the theory. In the analysis of direct detection
experiments, I focus on the interference of different dark matter-nucleon
interaction operators and on predictions observable at directional detectors.
Interpreting neutrino telescope observations, I use new nuclear response
functions recently derived through nuclear structure calculations and show that
hydrogen is not the most important element in the exclusion limit calculation
for the majority of the spin-dependent dark matter-nucleon interaction
operators
