  1. Episode 48: June 2018

    In this episode, we hear about why we always have space for dessert, how collecting seeds from large areas could help restoration projects, gut bacteria, the placebo effect and toxoplasmosis.
  2. 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.
  3. eLife and COVID-19: Keeping communications open with online research talks

    eLife hosts online seminars to support early-career researchers to present their research online instead of in person.
    1. Neuroscience

    A selective effect of dopamine on information-seeking

    Valentina Vellani et al.
    L-DOPA administration increases information-seeking about potential losses without impacting information-seeking about potential gains, and as a result, it reduces the effect of valence on information-seeking.
    1. Neuroscience

    Testicular hormones mediate robust sex differences in impulsive choice in rats

    Caesar M Hernandez et al.
    Sex differences in impulsive decision making, such that males are less impulsive than females, are critically dependent upon testicular but not ovarian hormones.
    1. Neuroscience

    Excitation of medium spiny neurons by ‘inhibitory’ ultrapotent chemogenetics via shifts in chloride reversal potential

    Stephanie C Gantz et al.
    Modifying membrane potential by an 'inhibitory' chloride conductance such as PSAM4-GlyR is inherently unstable because the normally low intracellular concentration of chloride is readily increased by influx of chloride.
    1. Neuroscience

    Heterogeneous somatostatin-expressing neuron population in mouse ventral tegmental area

    Elina Nagaeva et al.
    The midbrain area for salience, reward and aversion in mouse brain harbours among the dopamine cells three subtypes somatostatin-expressing neurons that show combinatorial neurotransmitter phenotypes and interneuron properties.
    1. Neuroscience

    Altered functional connectivity during speech perception in congenital amusia

    Kyle Jasmin et al.
    Individuals with amusia, who have unreliable pitch processing, show decreased functional connectivity between right auditory and left language-related cortex during speech perception, demonstrating a neural basis for compensatory dimensional weighting.
    1. Neuroscience

    Male-predominant galanin mediates androgen-dependent aggressive chases in medaka

    Junpei Yamashita et al.
    In medaka fish, galanin-expressing neurons in the medial preoptic area occur nearly exclusively in males and mediate androgen-dependent male–male aggressive chases.
    1. Neuroscience

    Different neuronal populations mediate inflammatory pain analgesia by exogenous and endogenous opioids

    Xin-Yan Zhang et al.
    Exogenous opioid analgesia is mediated by MORs expressed in glutamatergic neurons, whereas endogenous opioid analgesia is mediated by MORs expressed in GABAergic neurons.
