The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
A computational method identifies the functions of orphan enzymes by organizing them into metabolic pathways; the prediction of a new l-gulonate catabolic pathway is experimentally tested and confirmed.
In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.
Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.
The dorsolateral prefrontal cortex integrates concurrent externally and internally generated predictions of task demand to guide information processing, while the medial prefrontal cortex corrects its prediction error based on actual task demand.
Multiplexing and digital analysis of melanoma tissue describe functionally the microenvironment associated with brisk/non-brisk infiltrates and expose the functional incongruences of this morphological classification currently in use for tumor-infiltrating lymphocytes.
Variation in the gene NaMPK4 in plant populations increases reproductive yield, an effect which appears to be independent of soil water availability, neighbor-scale interactions and associations with arbuscular mycorrhizal fungi.
