Title: IceCube and the discovery of high energy neutrinos from extraterrestrial sources.  

Abstract:  
IceCube is a kilometer scale detector at the South Pole consisting of 5400 optical sensors that detect cosmic rays and neutrinos. The main array is shielded by 1.5 km of ice so that it can identify and reconstruct events generated by neutrinos, which are relatively rare compared to the background of atmospheric muons and neutrinos.  IceCube recently discovered the first evidence for neutrinos of high energy from extraterrestrial sources. In this talk I will describe the data and explain the significance of such a discovery. I will also describe how IceCube measures the spectrum of cosmic-ray particles and their relation to the neutrinos.

Title: On the Avoidance of Classical Singularities in Quantum Cosmology.  

Abstract:  
It is often claimed that a consistent theory of quantum gravity should avoid the singularities prediced by classical general relativity. While a general answer is not yet known, the fate of singularities can be investigated within simple models. In my talk, I shall discuss the quantum avoidance of classical singularities in quantum cosmology. I shall, in particular, address models where classically a singularity develops for large scale factors, such as a Big Rip or a Big Brake, and for which a quantum version without singularities exists. The discussion is performed within quantum geometrodynamics, that is, the Wheeler-DeWitt equation, but remarks are also made concerning the corresponding situation in loop quantum cosmology.
