    Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.

    An ancient yet flexible cis-regulatory architecture allows localized Hedgehog tuning by patched/Ptch1

    David S Lorberbaum et al
    The seemingly simple, constitutive response of the patched/Ptch1 gene to Hedgehog signaling is in fact regulated by large batteries of context-specific Hedgehog-responsive enhancers in both fly and mouse, allowing tissue-specific tuning of the Hedgehog pathway in animal development and evolution.

    Tethering of an E3 ligase by PCM1 regulates the abundance of centrosomal KIAA0586/Talpid3 and promotes ciliogenesis

    Lei Wang et al
    Ciliogenesis is regulated by a certain group of centriolar satellite proteins, among which an E3 ligase is tethered by PCM1 to maintain the normal level of pro-ciliogenic protein on centrioles.

    Hawkmoths evaluate scenting flowers with the tip of their proboscis

    Alexander Haverkamp et al
    Building on previous work (Kessler et al., 2015), it is shown that long-tongued hawkmoths assess individual flowers by smelling floral odors with olfactory neurons on their proboscises, and that this close-range perception is crucial for successful pollination and foraging.
