Hadronic Final States in e+e- Interactions and their Relevance to Cosmic Rays
Elementary particle physics using beams from accelerators and cosmic rays are compared. In particular, recent results on the energy evolution of charged particle multiplicities, the differences between quark and gluon jets, and scaling violations observed in electron-positron annihilation are described.

Multiparticle Aspects of e+e- Interactions at an Energy of 133 GeV at LEP
Electron-positron annihilations at an average center-of-mass energy of 133 GeV from the four LEP-experiments are presented. This includes in particular the total cross-section and multiplicities, thrust, rapidity and transverse momentum distributions as well as inclusive particle spectra.

Neutrino Astronomy: A New Window to the Universe
Neutrino astronomy offers the prospect to be able to look into the interior of compact astrophysical objects which may be the sources of cosmic radiation. This paper describes the results on neutrino observations from the sun and the supernova SN1987A along with an outlook on neutrino astronomy beyond the TeV scale.
