title: "Compact" nuclear domains: reconsidering the nucleolus.
abstract: The nucleolus is among the most striking cell components when viewed by phase contrast microscopy and yet, recent studies have revealed it to possess a lower molecular density than anticipated. A new report demonstrates that the nucleolus accommodates the assembly of a virus, this amidst building ribosomes and performing other host cell functions.
