  The last decade has been dense with new developments in the search for the
sources of Galactic cosmic rays. Some of these developments have confirmed the
tight connection between cosmic rays and supernovae in our Galaxy, through the
detection of gamma rays and the observation of thin non-thermal X-ray rims in
supernova remnants. Some other, such as the detection of features in the
spectra of some chemicals opened new questions on the propagation of cosmic
rays in the Galaxy and on details of the acceleration process. Here I will
summarize some of these developments and their implications for our
understanding of the origin of cosmic rays. I will also discuss some new
avenues that are being pursued in testing the supernova origin of Galactic
cosmic rays.
