From the BPS equations of junctions of domain walls, we consider a stable hexagonal configuration of network of brane-worlds, which are only approximately locally BPS. We propose a model for a mechanism of supersymmetry breaking, where a messenger for the SUSY breaking comes from the neighboring anti-BPS junction world, propagating along the domain walls connection them. We also consider implication to Dark Matter problem. We consider modification of the Newton's force law for brane world consisting of periodic configuration of branes, which supports a massless graviton. It is well separated from the Kaluza-Klein spectrum by a mass gap. As another application of recent development of string theory to Cosmology, we consider the Casimir effect on compact noncommutative space. We suggest a stabilization mechanism for a senario in Kaluza-Klein theory, where some of the extra dimensions are noncommutative.
