Developmental cell death plays a key role during insect neurogenesis and is increased in specific neuronal populations in flies that have evolved flightlessness.

A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.

Serotonin-releasing neurons show tonic firing-rate changes correlating with global reward value in addition to phasic firing-rate changes correlating with local task events.

Muscarinic acetylcholine receptor type A in adult Drosophila inhibits Kenyon cells, and is required for aversive olfactory learning and learning-associated synaptic depression between Kenyon cells and their output neurons.

Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

Attaching a molecule of adenosine mono-phosphate (AMP) to the BiP protein at threonine 518 regulates its chaperone activity in the endoplasmic reticulum.

A set of sexually dimorphic neurons in female flies is part of a recurrent neural network and drives minutes-long persistent neural activity and persistent social behaviors.

Lysine mono- and di-methylation are two novel post-translational modifications of RNA polymerase II, which are enriched at promoters of active genes, precede lysine acetylation and mark early stages of transcription.

Cleavage of pannexin-1 channel by caspases facilitates the loss of intracellular ATP level and attenuates glycolytic metabolism of apoptotic cells.

Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).
