ICRC 2017 - NU007 E. RESCONI SUMMARY ▸ The IceCube neutrinos are a natural challenge ▸ The 3FHL strengthen the hint of a possible connection neutrinos - HBLs ▸ Hint not confirmed with the new HESE data ▸ Neutrino filter effective to pin down candidates for UHECRs ▸ The new years of HESE show an under-fluctuation ▸ Interesting but inconclusive ▸ more data needed!!
