CONCORD generates denoised cell encodings that preserve key biological structures in single-cell datasets.

Myotonic dystrophy type 1 affects both muscle and neuronal function, but its synaptic pathology is poorly understood. Here, the authors show that upregulation of FasII (NCAM1) in both pre- and postsynaptic cells synergistically drives neuropathological and behavioral DM1 phenotypes, which can be rescued by FasII knockdown or specific isoform modulation.

The Cox’s Bazar area of Bangladesh has received a large number of Forcibly Displaced Myanmar Nationals. Cholera outbreaks have been detected in the area, and here, the authors perform genomic surveillance of cholera in the refugee and non-refugee population to infer the risk of epidemic spread.

Synthetic Notch (synNotch) receptors are genetically encoded, modular synthetic receptors that enable mammalian cells to detect environmental signals and respond by activating user-prescribed transcriptional programs. Here the authors apply synNotch receptors to spatially control differentiation of endothelial and skeletal muscle cells in a multicellular construct on assorted biomaterials.

Ageing is associated with muscle atrophy, which negatively impacts quality of life. Here the authors show that expression of sestrins decreases during inactivity and that their overexpression prevents atrophy in mice via modulation of autophagy and protein degradation.

Pandemic cholera was reintroduced to Argentina in 1992, leading to epidemic spread. Here, the authors use whole genome sequencing to show how, over 6 years, epidemic cholera was caused by invariant 7PET lineage Vibrio cholerae, against a background of sporadic disease caused by diverse local strains.

Structural analysis of Cas12a2, a CRISPR-associated nuclease that nonspecifically cleaves ssRNA, ssDNA and dsDNA, reveals a complete activation pathway involved in the abortive infection system protecting cells against invasion.

Methods for the analysis of metabolites in cells often require sample disruption and lack spatio-temporal resolution. Here, the authors show that Raman spectroscopy can directly detect fumarate in living cells and animal tissues ex vivo.

Using data from blue tits, the authors show that the distribution of juvenile body size is skewed due to environmental factors, and that although it does not affect selection estimates in this case, skew has the potential to overestimate heritability and explain discrepancies in predicted trait evolution.

Pluripotent stem cells can be generated from the somatic cells of humans and are a useful model to study disease. Here, pluripotent stem cells are made from a patient with familial Parkinson's disease, and the resulting neurons exhibit elevated levels of α-synuclein, recapitulating the molecular features of the patient's disease.

Shigella sonnei is one of the main species causing shigellosis worldwide. Here the authors analyse nearly 400 S. sonnei genome sequences and carry out experimental evolution experiments to shed light into the evolutionary processes underlying the recent emergence of fluoroquinolone resistance in this pathogen.

Mating of Candida albicans produces tetraploid products that return to the diploid state via a non-meiotic process known as concerted chromosome loss (CCL). Here, Anderson et al. show high recombination rates during CCL and identify factors that are essential for chromosome stability and recombination during CCL.

Quantum chaos is a useful framework for quantum many-body systems, but it has been mostly applied to isolated systems. Here the authors study the interplay of chaos and dissipation in open quantum circuits, showing that chaos is robust against weak dissipation but can also assist and anomalously enhance relaxation.

Heavy pnictogen-based compounds are promising nontoxic and stable alternatives to lead-halide perovskites, but are limited by carrier localization. Here, by investigating CuSbSe₂, the authors identify how this limitation could be avoided.

Although there are numerous immune mechanisms that destroy cancer precursors, the selection of tumour cells that are poorly immunogenic and that can subvert the immune response is crucial to the development of cancer. How these processes are linked is discussed in this Review.

How the brain’s antioxidant defenses adapt to changing demand is not well understood. Here the authors demonstrate that synaptic activity is coupled to transcriptional control of the glutathione antioxidant system via NMDA receptors, enabling neurons to tune their antioxidant defenses.

Reprogramming of somatic cells to induce pluripotent cellular properties that closely resemble those of embryonic stem (ES) cells has important therapeutic potential. The first whole genome single-base resolution profiling of the DNA methylomes of several human ES cell, induced pluripotent stem cell (iPSC) and somatic progenitor lines shows that iPSCs are fundamentally distinct from ES cells, insofar as they manifest common, quantifiable epigenomic differences. These 'hotspots of aberrant reprogramming' might be potentially useful as diagnostic markers for incomplete iPSC reprogramming, for the characterization of the efficacy of different reprogramming techniques, and for screening the potential propagation of altered methylation states into derivative differentiated cells.
