The superior colliculus reveals hallmarks of sophisticated visual computation, including selectivity, invariance, and stimulus-specific habituation to behaviorally relevant stimuli.

After shaking hands with a stranger, human volunteers often subliminally bring their hand to their nose and sniff it, possibly to collect important olfactory information.

Mice are able to discriminate plume intermittency, which may be used for odor-guided navigation.

A newly developed computational framework provides an overview of the extent, diversity, and relevance of the genes of unknown function in genomes and metagenomes.

Bioinformatics and experimental approaches identify families of membrane proteins requiring the co-ordinated action of the Sec pathway and Tat pathways for their integration and define features of the polypeptides that mediate interaction with these pathways.

Deconditioning is a safe and efficient new approach to updating traumatic memories, in which fear memory is rewritten to a very low level in a long-lasting way.

A conceptual and unifying framework with a critical appraisal of lipid hijacking by microbes cycling between an arthropod vector and a mammalian host is explored.

Dinucleases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.
