    Learning speed and detection sensitivity controlled by distinct cortico-fugal neurons in visual cortex

    Sarah Ruediger, Massimo Scanziani
    Neural pathways from mammalian visual cortex to ancestral brain structures control learning speed and performance of a simple detection task.

    Diffusion vs. direct transport in the precision of morphogen readout

    Sean Fancher, Andrew Mugler
    A theory predicts whether diffusion or direct transport establishes a more precise morphogen profile, and this prediction explains data from a wide variety of morphogens in two different organisms.

    Dynamics of nevus development implicate cell cooperation in the growth arrest of transformed melanocytes

    Rolando Ruiz-Vega et al.
    Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.

    Leptin receptor neurons in the dorsomedial hypothalamus regulate diurnal patterns of feeding, locomotion, and metabolism

    Chelsea L Faber et al.
    Synchronized feeding and metabolic patterns with environmental light–dark cycles is critical to maintain energy homeostasis and requires the activity of leptin-receptor neurons in the dorsomedial hypothalamus.

    Collateral sensitivity associated with antibiotic resistance plasmids

    Cristina Herencias et al.
    Acquisition of antibiotic resistance plasmids induces collateral sensitivity to clinically relevant antibiotics in Escherichia coli, paving the way for targeted 'anti-plasmid' therapies able to preferentially eliminate plasmid-carrying bacteria.

    Stem cell niche exit in C. elegans via orientation and segregation of daughter cells by a cryptic cell outside the niche

    Kacy L Gordon et al.
    A previously undetected dynamic cell structure orients the mitotic spindle of germ stem cells and grows over one daughter cell, thus helping to balance niche retention with niche exit.

    Repurposing of KLF5 activates a cell cycle signature during the progression from a precursor state to oesophageal adenocarcinoma

    Connor Rogerson et al.
    Genome-wide redistribution of KLF5 binding leads to activation of a cell cycle gene expression programme and proliferation control in oesophageal cancer.

    Phylogenetic variation in cortical layer II immature neuron reservoir of mammals

    Chiara La Rosa et al.
    The higher amount of cortical immature neurons in brains with expanded neocortices may represent a reservoir of young cells for mammals with reduced neurogenesis.

    Transverse sinus injections drive robust whole-brain expression of transgenes

    Ali S Hamodi et al.
    A new viral injection method targets the transverse sinuses to achieve robust whole-brain delivery of single or multiple genes in multiple mammalian species early in development.

    Bacterial survival in microscopic surface wetness

    Maor Grinberg et al.
    A new intricate reciprocity between microbiology and physics results in collective protection from desiccation through differential formation of stable microdroplets around bacterial aggregates on surfaces drying under moderate humidity.
