    Episode 2: July 2013

    In this episode we hear about plants doing maths, the evolution of cancer, why blood vessels don'€™t grow in the retina, the immune system and more.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    Translational regulation of protrusion-localized RNAs involves silencing and clustering after transport

    Konstadinos Moissoglu et al.
    RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.

    Autophagy regulates inflammatory programmed cell death via turnover of RHIM-domain proteins

    Junghyun Lim et al.
    Autophagy is critical for the turnover of inflammatory signaling complexes containing RHIM-domain proteins.
    1. Neuroscience

    Statistical structure of locomotion and its modulation by odors

    Liangyu Tao et al.
    A fly's locomotion can be decomposed into a small number of locomotor features which can be modulated by odors and other sensory information.
    1. Human Biology and Medicine

    Cardiovascular adaptation to hypoxia and the role of peripheral resistance

    Andrew S Cowburn et al.
    Radiotelemetric and genetic studies of peripheral tissue response show that a peripheral tissue can dynamically alter cardiovascular adaptation to changes in environmental oxygen.
    1. Neuroscience

    Parallel encoding of sensory history and behavioral preference during Caenorhabditis elegans olfactory learning

    Christine E Cho et al.
    Odor conditioning induces two changes in olfactory neurons: non-associative sensory adaptation to odor history, and associative, bidirectional changes in behavioral output that are oppositely regulated in aversive and appetitive learning.
    1. Developmental Biology

    Calcium handling precedes cardiac differentiation to initiate the first heartbeat

    Richard CV Tyser et al.
    High-resolution live imaging reveals how and when the mouse heart first starts to beat during development and how the onset of beating impacts on heart muscle cell maturation and heart formation.
    1. Cell Biology

    Asymmetric clustering of centrosomes defines the early evolution of tetraploid cells

    Nicolaas C Baudoin et al.
    Newly formed tetraploid cells rapidly lose extra centrosomes acquired upon tetraploidization via asymmetric centrosome clustering during cell division and selective advantage of tetraploid daughter cells that inherit a single centrosome.
