  Numerous investigations discuss neutrino properties from low to ultra high
energies. This review discusses several topics that are investigated in present
day experiments. The first section covers the detection of $\tau$-neutrinos of
cosmic origin and describes the significance of the results. The second topic
points out that the reported reduction of the antineutrino flux in reactor
experiments may be created by short wavelength oscillations where the detector
averages over several wavelengths and observes only an average reduction of the
antineutrino flux. In many theories the propagating particles are Majoranas and
have an anapole moment; they scatter on atomic electrons with a distinct
signature in $\bar\nu_e+e^-\rightarrow\bar\nu_e+e^-$ scattering.
