IceCube diffuse neutrino data constrains neutrino loss from new physics via energy conservation, yielding bounds that vary with attenuation energy dependence and source redshift assumptions while potentially affecting spectral index fits.
UHE neutrino flux is attenuated by DM scatterings in intergalactic and galactic media, enabling cross-section limits from events like KM3230213A under mild astrophysical assumptions.
