Abstract:
There are two main categories of searches for neutrinos of 
astrophysical origin, point sources and all-sky. Neutrino sources may be 
identified by a significant excess of events from the same direction 
and/or by coincidence in time and direction with an event identified 
electromagnetically or by gravitational waves. All-sky searches are made 
by looking for an excess of high-energy neutrino-induced muons from 
below the horizon and also by selecting events that start inside the 
detector.  In all approaches the main backgrounds are atmospheric 
leptons from cosmic-ray interactions in the atmosphere, but the 
backgrounds play a different role in each case.  In this talk, I will 
review recent results from IceCube while considering the effects of the 
atmospheric backgrounds in the different analyses.
