    Episode 27: February 2016

    In this episode we hear about midnight snacking, X-ray imaging of fossils, hummingbirds, monkeys gambling and axolotls regenerating.
  2. Episode 37: March 2017

    In this episode we hear about helping people with paralysis to communicate, how exposing mice to nicotine can affect their sons, scaffold-building parasites, the origins of handedness and plain-language summaries of research.

    RNF41 regulates the damage recognition receptor Clec9A and antigen cross-presentation in mouse dendritic cells

    Kirsteen M Tullett et al.
    Dendritic cell recognition and processing of antigens from dead cells, utilising the Clec9A-damage recognition receptor, is controlled by a novel RNF41-ubiquitin-mediated regulatory pathway.

    Manipulation of the human tRNA pool reveals distinct tRNA sets that act in cellular proliferation or cell cycle arrest

    Noa Aharon-Hefetz et al.
    Systematic CRISPR-based editing of tRNA genes revealed that different human cells that span a range of growth rates and different modes of proliferation states require diverse tRNA sets.

    Telomerase biogenesis requires a novel Mex67 function and a cytoplasmic association with the Sm7 complex

    Yulia Vasianovich et al.
    A new tool that allows specific subpopulations of telomerase RNAs in vivo forces a thorough revision of the telomerase maturation pathway and suggests a new function for Mex67.

    Genome-wide CRISPR screen identifies noncanonical NF-κB signaling as a regulator of density-dependent proliferation

    Maria Fomicheva, Ian G Macara
    TRAF3, a negative regulator of noncanonical NF-κB signaling, maintains epithelial cell quiescence at confluence, and its loss triggers upregulation of immunity genes and prevents entry into G0 at high cell density.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders et al.
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    Early prediction of level-of-care requirements in patients with COVID-19

    Boran Hao et al.
    Using data for 2566 COVID-19 patients from five hospitals, models are developed to predict for each patient hospitalization and critical care needs, based on demographics, comorbidities, medications, and laboratory findings.

    SWELL1 regulates skeletal muscle cell size, intracellular signaling, adiposity and glucose metabolism

    Ashutosh Kumar et al.
    LRRC8A is an essential component of a mechanoresponsive ion channel signaling complex that tunes skeletal muscle differentiation, muscle cell size, function and metabolic pathways to regulate adiposity and systemic glycemia.

    Transparent soil microcosms for live-cell imaging and non-destructive stable isotope probing of soil microorganisms

    Kriti Sharma et al.
    Two optically transparent substrates enable the exploration of the ecophysiology and spatiotemporal organization and activities of bacteria and fungi within heterogeneous soil-like environments.
