     Evaluation Summary:

     This paper is the first to characterize overdispersion of COVID-19 spread in schools using crowdsourcing . It has the potential to serve as a useful platform for assessing preventative measures in schools but needs more clarity regarding the sensitivity of the approach to the completeness of input data, as evidence by different model conclusions when sparse data from the US is used as an input as opposed to the more detailed Canadian data.

     Evaluation Summary:

     A challenge to understanding the physiology and therapeutic potential of G protein-coupled receptors (GPCRs) is to understand the range of their couplings to different G proteins. Avet et al developed of a novel set of biosensors to assess the coupling specificity of 100 therapeutically relevant G protein-coupled receptors (GPCRs) to various G protein isoforms and arrestins. The novel screen and results obtained with reference ligands will have broad use for researchers studying GPCRs, potentially impacting discovery of new physiological pathways, understanding adverse effects of currently marketed therapeutics, and discovery of novel, safer therapeutics.

     Evaluation Summary:

     Protein kinase A phosphorylation of phospholamban (PLN) is part of the "fight or flight" response, which ultimately increases the force of cardiac contraction. Mutations in PLN have been linked to familial dilated cardiomyopathy (DCM). Crystal structures of wild-type and mutant PLN in complex with the PKA catalytic domain provide insights into both the nature of the complex, and potential mechanisms by which DCM mutations may cause disease. This paper is of interest to scientists interested in the mechanism of substrate recruitment by protein kinases, and particularly those who have an interest in understanding the mechanism of mutations associated with dilated cardiomyopathy.

     Evaluation Summary:

     This manuscript describes a model of Ewing sarcoma , which represents an improvement upon previous zebrafish sarcoma models and the data suggest that the methods employed yield tumours that resemble human disease. This new model may be used to better understand sarcoma progression so that new therapeutic targets may be realised.

     Evaluation Summary:

     This study is a meta-analysis of previously reported studies on G protein-coupled receptor (GPCR) coupling to G proteins. Three separate data sets that describe the coupling of members of the superfamily of non-sensory GPCRs (~200 genes) to the large family of G protein alpha subunits (~20 genes). The authors try to arrive at a consensus for receptor-G protein coupling from the three data sets, as well as identify and highlight differences or incongruencies. Compiling these vast data sets into a unified format will be extremely useful for investigators to understand receptor and effector relationships. The meta-analysis will help to deconvolute the complex physiology and pharmacology underlying hormone or drug actions acting on receptor superfamilies.

     Wang et al. adapt a new statistical framework for a multi-site multi-year data set to investigate the effects of environmental variables on the temporal stability of plant communities and biomass productivity in Chinese grassland communities. This new framework may well turn out to be one that the larger ecological and ecosystem academic communities, interested in temporal changes of ecological processes across large spatial scales, have been looking for.

     Evaluation Summary:

     The authors demonstrate a molecular mechanism responsible for the rewiring of stroma cells that makes them supportive of acute myeloid leukaemia (AML) cells. Understanding metabolic interactions between leukaemia cells and the bone marrow microenvironment may provide new targets for leukaemia treatments. It has already been shown that the inhibition of gap junctions reduces AML growth in vivo, and here the authors provide evidence for a potential mechanism explaining that finding. The work will be very interesting for those working in the fields of hematopoiesis, leukemia (especially AML), cancer metabolism and cancer microenvironment.

     Evaluation Summary:

     This manuscript describes pioneering work providing detailed description of iPS-derived muscle fiber differentiation in culture. It demonstrates that muscle fibers show self-organising capacities in vitro and form bundles with identified attachment points; this self-organisation generates internal tension within myofibers. Overall, this study suggests that tension drives sarcomerogenesis in multi fibrillar vertebrate muscles and will be of interest to researchers in the muscle field and also biophysicists interested in collective cell behaviour.

     Evaluation Summary:

     This manuscript is of interest to readers in the field of microbiology and antimicrobial resistance. It reports that genetically identical antibiotic-sensitive bacteria can escape killing upon exposure to an otherwise lethal concentration of antibiotics because they have a low ATP level. The authors further attempt to demonstrate that variation in the level of expression of some genes in energy-generating metabolic pathways allows for a wide range of ATP levels among the cells in a population, thus generating a subpopulation with low ATP levels that can survive antibiotic exposure.

      Evaluation Summary:

      This paper uses single-cell genomics to examine the heterogeneity of virus-specific CD4 T cells over time in both acute and chronic viral infection. Further, the authors build a comprehensive atlas of the transcriptional evolution of virus-specific CD4 T cell responses that could be used as a reference tool to interpret other datasets. This work characterizes how the antiviral CD4 T cell transcriptional landscape changes with time and will be of broad interest to those that study acute and chronic CD4 T cell responses.
