title: For HIV, it's never too late to grow up.
abstract: Rather than being separated by discrete boundaries, the different phases of viral replication cycles partially overlap one another. In this issue, Dale et al. (2011) describe a remarkable example of this phenomenon: HIV-1 matures, and thus becomes infectious, but only after it has already started entering target cells.
