The stability of metabolic autocatalytic cycles that are widespread in central metabolism limits the affinities of enzymes at flux branch points and explains excess expression of these enzymes.
For perceptual inference, human observers do not estimate sensory uncertainty instantaneously from the current sensory signals alone, but by combining past and current sensory inputs consistent with a Bayesian learner.
Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.
Changes in the interpretation of specific scenes in a narrative trigger corresponding updates in the neural patterns evoked by those scenes in the default mode network.

Functional coupling between visual areas reflects supra-areal eccentricity organization distinct from overlapping receptive field connectivity during both rest conditions and naturalistic movie viewing.
A neural network showed better prediction of upcoming states when it was selective in when it encoded and retrieved episodic memories, thereby explaining why humans show this selectivity in studies of naturalistic memory.
Stem cell migration underlies head regeneration in the cnidarian (jellies and their kin) Hydractinia, but the regeneration of other body parts is based on the gradual transformation of one tissue type into another.
A 5'-UTR SNP of FGF13 impairs PTBP2 interacting with FGF13 mRNA, leading to reduced FGF13 translation and deficits in brain development and cognitive functions.
Human cell lines regress to become ‘de-sexualized’ by reconfiguring to a 2:3 X/A ratio of high fitness, thus shedding light on the evolution of mammalian sex chromosomes.
