    Apical length governs computational diversity of layer 5 pyramidal neurons

    Alessandro R Galloni et al.
    Layer 5 pyramidal neurons vary substantially in dendritic excitability between primary and secondary visual cortex, likely due to a counterintuitive amplifying effect of long apical dendrites.

    TMAO, a seafood-derived molecule, produces diuresis and reduces mortality in heart failure rats

    Marta Gawrys-Kopczynska et al.
    Trimethylamine-oxide (TMAO), a molecule present in seafood, reduces mortality and exerts beneficial effects on the circulatory system in heart failure rats.
  1. Episode 67: June 2020

    In this episode, we hear about a controversial claim in plant science, why we cannot get enough of chocolate, HIV in women, sex as a biological variable, and why not all zebrafish like to mingle.

    Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

    Joanne C Gordon et al.
    Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.

    Structure of substrate-bound SMG1-8-9 kinase complex reveals molecular basis for phosphorylation specificity

    Lukas M Langer et al.
    First structural view of a substrate-bound PIKK (PI3K-related-kinase) by cryo-EM explains phosphorylation specificity toward a short amino-acid motif shared across the PIKK family and rationalizes PIKK auto-inhibition by regulatory domain.

    Vestigial auriculomotor activity indicates the direction of auditory attention in humans

    Daniel J Strauss et al.
    Recordings of ear muscles in humans show that ears attempt to pivot in the direction that requires attention.

    Ant collective cognition allows for efficient navigation through disordered environments

    Aviram Gelblum et al.
    When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.
