  In this 2001 status report of the MACRO experiment, results are presented on
atmospheric neutrinos and neutrino oscillations, high energy neutrino
astronomy, searches for WIMPs, search for low energy stellar gravitational
collapse neutrinos, stringent upper limits on GUT magnetic monopoles,
nuclearites and lightly ionizing particles, high energy downgoing muons,
primary cosmic ray composition and shadowing of primary cosmic rays by the Moon
and the Sun.
