    Distinguishing different modes of growth using single-cell data

    Prathitha Kar, Sriram Tiruvadi-Krishnan ... Ariel Amir
    Single-cell data analysis must be guided by an underlying model.

    The complex relationship of exposure to new Plasmodium infections and incidence of clinical malaria in Papua New Guinea

    Natalie E Hofmann, Stephan Karl ... Ivo Mueller
    Under sustained malaria control in PNG, the incidence of distinct blood-stage infections quantifies heterogeneity in transmission, significantly predicting risk of both P. falciparum and P. vivax malaria episodes at a population and individual scale.

    Non-catalytic motor domains enable processive movement and functional diversification of the kinesin-14 Kar3

    Christine Mieck, Maxim I Molodtsov ... Stefan Westermann
    The kinesin-14 motor Kar3 moves along microtubules using a previously undescribed mechanism that critically requires the presence of a non-catalytic head.

    The Shu complex prevents mutagenesis and cytotoxicity of single-strand specific alkylation lesions

    Braulio Bonilla, Alexander J Brown ... Kara A Bernstein
    The Shu complex enables lesion bypass of specific alkylation-induced DNA damage including abasic sites and 3-methyl-cytosine.

    Contrasting effects of Ksr2, an obesity gene, on trabecular bone volume and bone marrow adiposity

    Gustavo A Gomez, Charles H Rundle ... Subburaman Mohan
    Obese Ksr2 mutant mice have increased trabecular bone but decreased marrow adiposity and are more prone to fractures, thus providing a useful model to understand how stem cells can be manipulated to produce bone at the expense of marrow fat.

    KAT2-mediated acetylation switches the mode of PALB2 chromatin association to safeguard genome integrity

    Marjorie Fournier, Amélie Rodrigue ... Fumiko Esashi
    The lysine acetyltransferases KAT2A and KAT2B regulate the dynamic chromatin association of the tumour suppressor protein PALB2, protecting active genes and promoting DNA damage repair in a context-dependent manner.

    Theta- and gamma-band oscillatory uncoupling in the macaque hippocampus

    Saman Abbaspoor, Ahmed T Hussin, Kari L Hoffman
    Oscillations that co-occur in hippocampal CA1 during exploration in the rodent are shown to segregate according to exploratory and sleep states in the primate.

    Selective activation of FZD7 promotes mesendodermal differentiation of human pluripotent stem cells

    Diana Gumber, Myan Do ... Karl Willert
    Selective activation of FZD7 signaling with an engineered WNT mimetic promotes early developmental programs, including endodermal lineage specification, in human pluripotent stem cells.

    Unified mechanisms for self-RNA recognition by RIG-I Singleton-Merten syndrome variants

    Charlotte Lässig, Katja Lammens ... Karl-Peter Hopfner
    RIG-I Singleton-Merten syndrome mutations either mimic or freeze the protein in an ATP-bound state and lead to autoimmune signalling through a gain-of-function recognition of self-RNA.

    ATP hydrolysis by the viral RNA sensor RIG-I prevents unintentional recognition of self-RNA

    Charlotte Lässig, Sarah Matheisl ... Karl-Peter Hopfner
    Mutations within the ATPase domain of RIG-I in patients with Singleton-Merten Syndrome prevent ATP-hydrolysis dependent dissociation of RIG-I from double-stranded RNA and lead to unintentional constitutive signaling through increased binding of endogenous RNA.
