  A small, natural abundance, germanium detector (COSME) has been operating
recently at the Canfranc Underground Laboratory (Spanish Pyrenees) in improved
conditions of shielding and overburden with respect to a previous operation of
the same detector. An exposure of 72.7 kg day in these conditions has at
present a background improvement of about one order of magnitude compared to
the former operation of the detector. These new data have been applied to a
direct search for WIMPs and solar axions. New WIMP exclusion plots improving
the current bounds for low masses are reported. The paper also presents a limit
on the axion-photon coupling obtained from the analysis of the data looking for
a Primakoff axion-to-photon conversion and Bragg scattering inside the crystal.
