    Regulatory small RNA (sRNA) interact with mRNAs to regulate their stability, transcription, and translation via diverse mechanisms. Here, McKellar et al. apply RNase IIICLASH of multi-drug resistant Staphylococcus aureus under different culture conditions to link the network of RNA-RNA interactions to environmental conditions and find that the production of small membrane-permeabilizing toxins is strongly regulated by sRNAs.

    Mechanistic models of how single cells respond to different perturbations can help integrate disparate big data sets or predict response to varied drug combinations. Here the authors develop a scalable, open-source pipeline for constructing and simulating large-scale, single-cell mechanistic models, an important building block for clinically-predictive mechanistic models and interpretable big data integration.

    Stable-isotope tracing allows quantifying metabolic activity by measuring isotopically labeled metabolites, but its metabolome coverage has been limited. Here, the authors develop a global isotope tracing approach with metabolome-wide coverage and use it to characterize metabolic activities in aging Drosophila.

    Animals must reach the correct size during development, despite stochastic differences in their growth rate. Here, Stojanovski et al. show that a coupling of growth and development by an oscillatory timer buffers fluctuations in the growth of the nematode C. elegans to ensure its correct size.

    Anti-cancer cytotoxic T cell responses largely vary among individuals. Here authors show, by stochastic modeling on high throughput T cell behavior and matched tumor spheroid fate data generated by a microfluidics system, that tumor killing is dependent on T cell cooperativity, which might contribute to the heterogeneity of T cell responses.

    Quorum-sensing bacteria produce and secrete autoinducers that trigger a behavioral change in the population when reaching a certain threshold. Here, Bettenworth et al. show that autoinducer synthase gene expression in Sinorhizobium meliloti occurs in asynchronous stochastic pulses, and that physiological cues modulate pulse frequency and, consequently, response behavior dynamics. Frequency-modulated pulsing in autoinducer synthase gene expression thus represents a time-based mechanism for information integration and collective decision-making.

    A major challenge in coronavirus vaccination and treatment is to counteract rapid viral evolution and mutations. Here the authors show that CRISPR-Cas13d can be used as a broad-spectrum antiviral to inhibit human coronaviruses, including new SARS-CoV-2 variants, combined with small molecule drugs for an enhanced antiviral effect in human primary cells.

    Global diversity trends in the fossil record vary regionally through time and space, affecting our ability to interpret macroevolutionary history. Here, the authors propose a method to eliminate spatial sampling bias, estimate origination and extinction rates, and generate diversity estimates, applying this method to the Late Permian to Early Jurassic marine fossil record.

    Light-oxygen-voltage (LOV) photoreceptors perceive blue light to elicit spatio-temporally defined cellular responses, and their signalling process has been extensively characterized. Here the authors report that the light signal is still transduced in the absence of a conserved Gln residue, thought to be key.

    T cell large granular lymphocytic leukemia (T-LGLL) is a lymphoproliferative disorder involving clonally expanded T cell clones and is not fully understood. Here the authors show that the rest of the immune repertoire is interconnected with the T-LGLL clonotype(s) and is more mature, cytotoxic and clonally restricted than in other cancers and autoimmune disorders.
