The genome of a tiny tomato pest reveals mechanisms that underlie metazoan genome reduction.

Tucked within a well-known story of diverging gene function is a single enhancer encoding two inseparable specificities that regulates two adjacent genes, each with different spatiotemporal expression patterns.

Analysis of the smallest known arthropod genome reveals a mechanism for genome reduction that appears to be driven by a specialized ecological interaction with plants.

The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.
