An interesting article that I came across from sciam.com regarding black holes.  This article is describing a newly discovered black hole at the "center" of a dwarf galaxy which was previously not known to have a super massive black hole.  It may turn out that all galaxies may contain super massive black holes and not just the one's with a "galactic bulge".  I wonder if this means we have to recalculate the "missing mass" in the universe currently attributed to dark mater.
