Analysis of the available expressed sequence tags (ESTs) for one cultivated and two wild tomato species highlights sets of genes and polymorphisms with potential significance for the evolution and domestication of this important crop.

Promoter occupancy profiles for the related tumour suppressor proteins p53 and p73 identify many promoters bound by both but also a distinct set bound by p73 in response to genotoxic stress.

Activation of growth factor (GF) signalling contributes to the tamoxifen-insensitive estrogen receptor-positive breast cancer phenotype independent of human epidermal growth factor receptor (HER2) gene expression, suggesting an alternative therapeutic target for this aggressive disease.

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.
