    The resolution limitations when using the ubiquitous algorithms that process images obtained using modern techniques are not straightforward to define. Here, the authors examine the performance of localization algorithms and use spatial statistics to provide a metric for assessing the resolution limit of such algorithms.

    PurR acts as transcriptional repressor of purine biosynthesis genes in some bacterial species. Here, the authors show that purR mutations can arise in Staphylococcus aureus upon exposure to stress, leading to upregulation of fibronectin-binding proteins and increased virulence.

    Triple negative breast cancers (TNBC) disseminate and metastasise, but the clonal relationship of metastases to primary tumours is poorly understood. Here, the authors use cellular barcoding of TNBC patient-derived xenografts and track the fate of barcoded clones in primary tumours and their metastases, including after resection or chemotherapy.

    BCL9 and Pygo are components of Wnt enhanceosome, which facilitates β-catenin-dependent transcription. Here, the authors show that deletion of Bcl9 and Pygo suppresses tumorigenesis and extends disease free survival in two different colorectal cancer models, suggesting a strategy for drugging β-catenin signalling in this cancer.

    Auxin transport and microtubule orientation respond to mechanical stimulation at the shoot apical meristem. Here Li et al. show that mechanical stimulation causes cytosolic calcium concentration transients, and preventing such changes impairs reorientation of the PIN1 auxin efflux carrier, but not of microtubules.

    How HIV reservoirs are shaped over time on antiviral therapy is poorly understood. Here, the authors analyze the dynamics of the HIV reservoir by longitudinal proviral sequencing revealing that HIV reservoir expression can contribute to its clearance and paradoxically even to its persistence.

    Targeting histone acetylation modulators (HAMPs) is a promising avenue of drug discovery in cancer research. Here, the authors integrate multi-dimensional genomic profiles to systematically investigate recurrent genomic alterations in HAMPs, identifying potential therapeutic targets for precision epigenetic treatment.

    Quaternary contacts mediated by an extended heavy-chain framework region 3 (FR3) have been shown to improve binding to HIV envelope and virus neutralization for a few antibodies. Here, Liu et al. engraft such an FR3 loop onto several potent broadly neutralizing antibodies, resulting in improved neutralization activity and pharmacokinetics.
