    Multiscale analysis reveals that diet-dependent midgut plasticity emerges from alterations in both stem cell niche coupling and enterocyte size

    Alessandro Bonfini et al.
    The nutrient composition of food alters both the size of gut epithelial cells and the ability of the stem cell niche to control tissue turnover, resulting in changes in size at the organ level.

    Metformin alleviates stress-induced cellular senescence of aging human adipose stromal cells and the ensuing adipocyte dysfunction

    Laura Le Pelletier et al.
    Aging is associated with stress-induced senescence of adipose stromal cells, leading to impaired adipogenesis, oxidative stress, mitochondrial dysfunction, and insulin resistance, all being alleviated by metformin treatment of adipose stromal cells.

    The structure of behavioral variation within a genotype

    Zachary Werkhoven et al.
    Multidimensional analysis of data from high-throughput behavioral assays reveals many independent axes of behavioral variation among inbred animals reared in the same environment.

    Conformational changes in twitchin kinase in vivo revealed by FRET imaging of freely moving C. elegans

    Daniel Porto et al.
    Quantitative FRET imaging in moving C. elegans shows that stretch-unfolding of twitchin kinase occurs in the active muscle, whereby mechanical activity titrates the signaling pathway of this cytoskeletal kinase.

    Competitive binding of MatP and topoisomerase IV to the MukB hinge domain

    Gemma LM Fisher et al.
    Topoisomerase IV and the ter-binding protein MatP competitively bind the hinge domain of the Escherichia coli Structural Maintenance of Chromosomes complex, MukB, leading to spatiotemporal regulation of MukBEF-topoisomerase IV activity.

    Myogenin controls via AKAP6 non-centrosomal microtubule-organizing center formation at the nuclear envelope

    Robert Becker et al.
    Myogenin promotes centrosome attenuation and establishes the nuclear envelope as the dominant microtubule organization center via the scaffold protein AKAP6, which is required for the recruitment of centrosomal proteins.
  1. Episode 76: October 2021

    In this episode, we hear about the ways that junk food affects monkeys, grey hair, empathetic rats, using smart phones to fight COVID-19, and how the slave trade spread disease.

    Structure of mycobacterial CIII2CIV2 respiratory supercomplex bound to the tuberculosis drug candidate telacebec (Q203)

    David J Yanofsky et al.
    The structure of the Mycobacterium smegmatis CIII2CIV2 respiratory supercomplex with telacebec (Q203) bound shows how this tuberculosis drug candidate blocks respiration in mycobacteria.

    Microglia and CD206+ border-associated mouse macrophages maintain their embryonic origin during Alzheimer’s disease

    Xiaoting Wu et al.
    Inducible fate-mapping analysis demonstrates that neither microglia, CD11c+ activated microglia nor border-associated macrophages are replenished by bone marrow-derived cells in Alzheimer’s disease.
