    Impaired ABCA1/ABCG1-mediated lipid efflux in the mouse retinal pigment epithelium (RPE) leads to retinal degeneration

    Federica Storti et al.
    Lipid efflux by the retinal pigment epithelium is crucial for proper retinal integrity and function, and its impairment may contribute to diseases like age-related macular degeneration.

    Single cell RNA-seq identifies the origins of heterogeneity in efficient cell transdifferentiation and reprogramming

    Mirko Francesconi et al.
    Variation in efficiency, speed and path during transdifferentiation and reprogramming originates from two pre-B cell subpopulations with reciprocal propensity towards each fate conversion.

    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou et al.
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    Across-species differences in pitch perception are consistent with differences in cochlear filtering

    Kerry MM Walker et al.
    Humans and other animals have different strategies for extracting the pitch of sounds, potentially driven by the species-specific frequency selectivity of the ear.

    Ventrolateral periaqueductal gray neurons prioritize threat probability over fear output

    Kristina M Wright, Michael A McDannald
    Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.

    Hippocampus: Getting the full picture

    Alessandro Luchetti et al.
    A combination of old and new techniques have been used to reveal new details about the behavior of individual neurons across the sleep-wake-cycle.

    The cryo-EM structure of a 12-subunit variant of RNA polymerase I reveals dissociation of the A49-A34.5 heterodimer and rearrangement of subunit A12.2

    Lucas Tafur et al.
    Cryo-EM structures of RNA polymerase I reveal considerable 'transformers-like' rearrangements where one subcomplex dissociates and is replaced by one domain of another subunit, possibly as an additional layer of transcriptional control.

    A conserved major facilitator superfamily member orchestrates a subset of O-glycosylation to aid macrophage tissue invasion

    Katarina Valoskova et al.
    T antigen glycosylation, which marks metastatic cancer cells, is modulated on a small set of proteins by a conserved multipass transmembrane protein to allow tissue invasion by Drosophila macrophages.

    Non-canonical RNA-directed DNA methylation participates in maternal and environmental control of seed dormancy

    Mayumi Iwasaki et al.
    Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.
