A new and validated genome-scale metabolic model of Bacillus subtilis 168, iBsu1103, is presented that has significantly improved completeness and accuracy.

A proteomic and metabolic network analysis of honeybee queen spermathecal fluid provides insights into female long-term sperm storage mechanisms.

Calcium is necessary and sufficient to form long-term memory in honeybees during odor conditioning experiments, and acts as the switch between short- and long-term memories.

A novel evolutionary analysis of metabolic networks across 26 taxa reveals a highly-conserved but flexible core of metabolic enzymes.

Aggressive behavior in Drosophila melanogaster is a complex trait and 57 genes influencing aggression levels have now been identified in a screen of fly lines carrying P-element insertions.
