Query: Recent highlights from ARGO-YBJ   The ARGO-YBJ experiment has been in stable data taking for 5 years at the
YangBaJing Cosmic Ray Observatory (Tibet, P.R. China, 4300 m a.s.l., 606
g/cm^2). With a duty-cycle greater than 86% the detector collected about 5 X
10^{11} events in a wide energy range, from few hundreds GeV up to the PeV. A
number of open problems in cosmic ray physics has been faced exploiting
different analyses. In this paper we summarize the latest results in gamma-ray
astronomy and in cosmic ray physics
