title: Hungry flies tune to vinegar.
abstract: Many molecular signals that represent hunger and satiety in the body have been identified, but relatively little is known about how these factors alter the nervous system to change behavior. Root et al. (2011) report that hunger modulates the sensitivity of specific olfactory sensory neurons in Drosophila and facilitates odor-search behavior.
