A new platform for imaging live Drosophila adults yields vivid movies of the midgut over prolonged time scales, opening the door to the real-time study of organ renewal dynamics in a near-native context.

The protozoan parasite Trypanosoma brucei gambiense has undergone recent clonal evolution that reveals the theoretically predicted Meselson effect at a genome-wide level.

The human visual system uses sharp edges to distinguish a smooth, shaded surface from a surface blurred by optical defocus.

Deep inside the temporal lobe of the brain, the hippocampus has a central role in our ability to remember, imagine and dream.

Our ability to recall details from a remembered image depends on a single mechanism that is engaged from the very moment the image disappears from view.

Direct recordings from the human hippocampus reveal the neural mechanisms that orchestrate recollection of past experiences.

Visual and prefrontal cortex excitability predict individual differences in visual imagery strength, and modulating excitability in these cortical regions causally alters the strength of visual imagery.

Autistic traits are associated with weaker influence of prior expectations in visual perception, which is due to more precise sensory representations.

Rodent model of context-dependent discrimination reveals sex-biased tradeoff between speed of acquisition and robustness of contextual control over cue-elicited reward seeking, linked to orbitofrontal cortex activation.

Emotional learning retroactively promotes memory integration for previously neutral events into episodic memory to foster future event predictions, through rapidly stimulating trial-specific reactivation of overlapping memory traces and reorganization of associated memories among the amygdala, hippocampal, and neocortical circuits.
