    Mechanical instability and interfacial energy drive biofilm morphogenesis

    Jing Yan, Chenyi Fei ... Bonnie L Bassler
    Mechanical instabilities are shown to underlie the development of bacterial biofilm morphology, suggesting an ancient origin for mechano-morphogenesis, which is known to drive developmental processes in tissues in higher organisms.

    Learning protein constitutive motifs from sequence data

    Jérôme Tubiana, Simona Cocco, Rémi Monasson
    A new machine-learning toolbox unveils coevolutionary protein motifs related to structure, function, and phylogeny from sequence information only.

    Upper bound on the biological effects of 50/60 Hz magnetic fields mediated by radical pairs

    PJ Hore
    Any effects of environmental 50/60 Hz magnetic fields on human biology due to a radical pair mechanism should be no more dangerous than those incurred by travelling a few kilometres.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu, Simona Cocco ... Vijay Balasubramanian
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.

    The proneural wave in the Drosophila optic lobe is driven by an excitable reaction-diffusion mechanism

    David J Jörg, Elizabeth E Caygill ... Benjamin D Simons
    A model of signalling pathways interacting with proneural gene expression explains the sequential patterning of the largest visual processing centre in the developing Drosophila brain.

    Negative reciprocity, not ordered assembly, underlies the interaction of Sox2 and Oct4 on DNA

    John W Biddle, Maximilian Nguyen, Jeremy Gunawardena
    Rigorous reanalysis of single-molecule data yields evidence for energy expenditure in the interaction of transcription factors on DNA.

    Spatial and temporal organization of RecA in the Escherichia coli DNA-damage response

    Harshad Ghodke, Bishnu P Paudel ... Antoine M van Oijen
    Phase separated DNA-free stored forms of RecA dissolve in response to DNA damage to make RecA available for repair and recombination reactions as part of the bacterial (Escherichia coli) SOS response.

    A first order phase transition mechanism underlies protein aggregation in mammalian cells

    Arjun Narayanan, Anatoli Meriin ... Ibrahim I Cisse
    Quantitative single molecule and super resolution imaging in mammalian cells reveal a population of precursor aggregates describable by first order phase transition theory.

    High-molecular-weight polymers from dietary fiber drive aggregation of particulates in the murine small intestine

    Asher Preska Steinberg, Sujit S Datta ... Rustem F Ismagilov
    Polymers from dietary fiber can control the aggregation of particulates in the murine small intestine in a manner qualitatively consistent with depletion interactions.

    Rapid changes in tissue mechanics regulate cell behaviour in the developing embryonic brain

    Amelia J Thompson, Eva K Pillai ... Kristian Franze
    During embryonic development, tissue stiffness, which provides an important signal to motile cells, changes locally within tens of minutes in a well-controlled manner.
