Pathogenic variants in UNC13A underlie a novel neurodevelopmental syndrome, with three subtypes defined by distinct genotypes with varying clinical and functional impacts characterized in cellular and animal models.

Antimatter remains an enigma – its absence in the universe is hitherto unexplained. Here, the authors report a breakthrough in the ability to study antihydrogen atoms to test fundamental symmetries. Antihydrogen atoms can now be accumulated at CERN at the previously unattainable rate of 2000 per hour.

Here, the authors present results of the ZiBRA-2 project (https://www.zibra2project.org) which is an arbovirus surveillance project, across the Midwest of Brazil using a mobile genomics laboratory, combined with a genomic surveillance training program that targeted post-graduate students, laboratory technicians, and health practitioners in universities and laboratories.

The pathogenic avian flu H5N1 virus remains stable in raw milk and throughout the cheese-making process, but contaminated cheese fed to ferrets did not lead to infection, whereas raw milk did.

Previous models explain solid-solution strengthening by differences in atomic volume and electronegativity of the constituent atoms. Here, the authors consider both factors simultaneously and identify atomic volume as the dominant factor for FCC alloys.

Head and neck squamous cell carcinoma (HNSCC) frequency and risk factors vary considerably across regions and ancestries. Here, the authors conduct a multi-ancestry genome-wide association study and fine mapping study of HNSCC subsites in cohorts from multiple continents, finding susceptibility and protective loci, gene-environment interactions, and gene variants related to immune response.

Analysing >1,700 inventory plots from the Amazon Tree Diversity Network, the authors show that the majority of Amazon tree species can occupy floodplains and that patterns of species turnover are closely linked to regional flood patterns.

Data from a variety of sources—including satellite, climate and soil data, as well as field-collected information on plant traits—are pooled and analysed to map the functional diversity of tropical forest canopies globally.

The receptor-like kinase NIK1 is phosphorylated in response to multiple biotic and abiotic signals, activating the NIK1/RPL10/LIMYB signaling circuit, which coordinately regulates translation and photosynthesis in response to environmental changes.
