  HiRes has made the first statistically significant observation of the
Griessen-Zatsepin-Kuzmin suppression, by fitting the ultra high energy cosmic
ray spectrum observed in monocular mode by the two HiRes detectors to a broken
power law model. We find the break to be at an energy of $5.6\times10^{19}$ eV,
with a significance of $5.3\sigma$;. The significance is determined by Poisson
statistics where we expect 43.2 events above the break point, but observe only
13. We have also looked for correlations between HiRes stereo events and active
galactic nuclei. We observe no statistically significant correlation in a
number of different tests. We have performed a search for upward going showers,
which would be indicative of neutrinos propagating through the Earth and
interacting just below the surface. Observing no such events, we set a limit on
the electron neutrino flux. This limit is significantly lower in this topology
than limits on the other types of neutrinos due to the LPM effect greatly
increasing the available target mass for neutrino interactions. Finally we look
forward to improving these and other results in our work in the Telescope
Array.
