An analysis of the genomic features that distinguish conserved from species-specific circular RNAs reveals that the expansion of the downstream intron by insertion of retrotransposons stabilizes circular RNAs' production across 30+ millions years of evolution.
Evolutionary analyses suggest that most mammalian circRNAs did not emerge from common ancestral circRNA precursors, arguing against widespread functional conservation.

A viable separation of function XRCC4 knock-in mutant mouse model recapitulates some aspects of XRCC4 deficiency in humans, notably the absence of immune deficiency.
Electrophysiological and live-cell imaging analyses identify a presynaptic function of Ca2+ influx via transient receptor potential melastatin 7 (TRPM7) channels.

Hippocampal activity during memory recall predicts a transient increase in the ratio between neocortical glutamate and GABA, thereby allowing otherwise dormant memories to be released.

Inhibitory synaptic plasticity provides a flexible and biologically plausible circuit mechanism to detect the novelty of bottom-up stimuli and to generate stimulus-specific adaptation.
A circuit between the hippocampus, nucleus reunions, and prefrontal cortex organizes information about the past, present, and future into alternating theta sequences.
A theory of gut bacterial aggregation produces a cluster size distribution that matches that of several strains observed in zebrafish, suggesting principles generally applicable to the vertebrate gut.
