A Korean study of 338 adults finds that subthreshold manic tendencies, flagged by a short screening questionnaire, track with higher anxiety, depression, and disrupted daily rhythms regardless of how badly a person sleeps.
Whole genomes from 49 Yellow-whiskered Greenbuls across Africa split into western, central, and eastern lineages that match long-hypothesized Pleistocene forest refuges, but the eastern lineage's mitochondrial DNA turns up deep inside central birds that otherwise share almost none of its genome.
A randomized experiment inside a multinational firm finds that chatbots reliably boost speed, while their effect on quality flips depending on the task.
Many tissue structures are really one-dimensional, a gut lining, a layered ribbon of cells, and a Harvard-led team argues that measuring gene expression along that shape, rather than across a flat map, finds patterns that two-dimensional methods miss.
Two-photon imaging of the memory-forming CA1 region found cells that idled too loudly and responded too weakly when the animal ran, with the worst disruption in tissue closest to amyloid plaques.
Researchers ran a week of UK Biobank accelerometer data through two frozen self-supervised models and predicted the future onset of 390 diseases, with the sharpest signal appearing years before Parkinson's disease was diagnosed.
Researchers sampled weathered butts, plant litter, and soil in 105 urban parks and found that butt-dwelling bacterial communities were consistently dominated by fast-growing Pseudomonadaceae carrying more antibiotic-resistance and virulence genes than their neighbours.
