Motor units in the superior colliculus of mice exhibit poorly defined representation of static visual fields and instead rely largely on kinetic visual features to link visual inputs to behavioural outcomes.

Primary and metastatic tumours have different metabolic phenotypes due to changes in nutrient availability. Here the authors perform multi-omic analyses of primary and metastatic renal cancer cells grown in a physiological medium and show that the reprogramming of the branched-chain amino acid catabolism and urea cycle through re-expression of ASS1 allows metabolic flexibility during renal cancer progression.

Here the authors apply ZooMS, radiocarbon, and stable isotope analyses to whale bones from the Bay of Biscay. They find that humans were utilizing the remains of at least five species of whales from 20,000 years ago, and that those whale communities may have resembled today’s arctic waters.

Geospatial estimates of the prevalence of anemia in women of reproductive age across 82 low-income and middle-income countries reveals considerable heterogeneity and inequality at national and subnational levels, with few countries on track to meet the WHO Global Nutrition Targets by 2030.

Using a conceptual framework known as the integrative hypothesis of specialization, the authors suggest that phylogenetic constraints separate species into different layers and shape the modules of a Neotropical network composed of the frugivorous and nectarivorous interactions between bats and plants.

The safety and efficacy of ribonucleoproteins for genome editing can be enhanced by formulations of lipid nanoparticles optimized for enhanced stability, delivery efficiency and editing potency of the protein complexes.

Tightness-looseness theory predicts that social norms strengthen following threat. Here the authors test this and find that, after the emergence of the COVID-19 pandemic, hand washing norms increased, but no evidence was observed for a robust change in most other norms.

Here the authors screen different lipid nanoparticle (LNP) formulations for intramuscular delivery of plasmid DNA and uptake by antigen-presenting cells. The lead LNP exhibits immunogenicity and protection in small animal models that is comparable to approved SARS-CoV-2 mRNA vaccine formulations.

Colonna and colleagues show that the transcription factor Aiolos controls chromatin accessibility and histone acetylation at genes linked to the activation of intestinal intraepithelial lymphocytes.

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

Tumour-associated myeloid cells have been linked to patient outcome and treatment response in multiple cancer types. Here, the authors use deconvolution of single cell RNA-sequencing data to identify myeloid populations which are prognostic across cancer types.

The species threat abatement and restoration (STAR) metric quantifies the contributions that abating threats and restoring habitats offer towards reducing species’ extinction risk in specific places.

In the first results from an ongoing global cancer screening data repository, screening program organization was better overall in Europe compared to other continents; however, there were substantial gaps in implementation across both high- and low-resource settings.

Combination of epidemiology, preclinical models and ultradeep DNA profiling of clinical cohorts unpicks the inflammatory mechanism by which air pollution promotes lung cancer

The biological understanding of poor prognosis associated with lymph node metastasis in head and neck cancer (HNC) remains crucial. Here, a proteomic characterisation of 140 multisite samples from a 59-HNC patient cohort and machine learning reveals potential biomarkers and metastasis related signatures.

Crystallographic snapshots illustrate the catalytic cycle and illuminate the mechanism by which the enzyme Pdx1 shuttles intermediates between lysine residues in its two active sites during the biosynthesis of pyridoxal 5′-phosphate.

Indole-5,6-quinone (IQ) is a long-sought intermediate and structural subunit of eumelanin pigments whose instability has precluded isolation and characterization. It has now been shown that a sterically shielded derivative of IQ exhibits hallmark eumelanin properties, including near-infrared absorption, ultrafast nonradiative decay and a persistent semiquinone radical formed by comproportionation.

IL-23 produced by myeloid-derived suppressor cells regulates castration resistance in prostate cancer by sustaining androgen receptor signalling.

Although plant functional trait combinations reflect ecological trade-offs at the species level, little is known about how this translates to whole communities. Here, the authors show that global trait composition is captured by two main dimensions that are only weakly related to macro-environmental drivers.

In this study, the authors report that pluripotent stem cell-derived ventricular progenitors target loss of myocardium and fibrotic scarring to promote heart regeneration, thus offering new potential therapeutic strategies for heart injury.

Adult forms of inflammatory bowel disease (IBD) are of a polygenic nature, but paediatric and very early onset (VEO) IBD also occur as monogenic forms. Here, using whole exome sequencing, the authors explore both the monogenic and polygenic contribution to VEO-IBD and characterize a rare somatic mosaic VEO-IBD patient.

Cancer cells can actively engage in overcoming microenvironmental constraints such as tissue stiffness through adapting their shapes; however it is unclear how microenvironmental cells shape cancer nuclear morphology in human tumors in situ. Here the authors merge machine learning, digital pathology and spatial statistics to study this issue; furthermore the authors identify decreased immune infiltration in the surrounding of diversified cancer cells in a subset of ovarian tumors.
