  • Food production, especially of animal products, is a major source of air pollutants. Here, the authors quantify the impacts dietary changes towards more plant-based diets could have for air quality, labour productivity, and human health.

  • Heat and moisture stress can reduce carbon uptake by forests. Here, the authors quantify this effect for the extreme 2022 European summer drought. The widespread reduction of photosynthesis exceeded the large local carbon release by intense fires.

  • The Great Atlantic Sargassum Belt is a hazard for coastal communities. Elevated N and P in the GASB are measured, with As content reflecting P limitation. Nutrient availability causes GASB blooms but reducing P would increase As accumulation.

  • Processes controlling the onset of the Antarctic sea ice season remain unclear. Here, analyses of observations show that ocean solar energy storage and sea ice drift are key drivers, providing insights to understand variations in sea ice season duration.

  • Despite the significance of mosquitos for human health, little research has focused on their phylogeny. Here, the authors present a resolved phylogenetic history of mosquitoes based on phylogenomics showing that these major disease vectors radiated coincidentally with geologic events and the diversification of their hosts.

  • Single reference genomes and short-read sequencing data are not enough to harness the full genetic variation of a species. Here, the authors report pan-genome of Arabidopsis thaliana based on chromosomal-level genomes of 32 accessions and identify variations associated with local adaptation.

  • YTHDF2 has been extensively studied as an m6A-related RNA metabolism. Here, the authors show that YTHDF2 also contributes to protein homeostasis in an m6A-independent manner by promoting the formation of aggresomes through its interaction with UPF1.

  • Deep learning models can reflect and amplify human bias, potentially resulting inaccurate missed diagnoses. Here, the authors show that by leveraging the marginal pairwise equal opportunity, their model reduces bias in medical image classification by over 35% compared to baseline models, with minimal impact on AUC values.

  • Natural variability in menstrual cycle length with rapid changes in gene expression makes it difficult to accurately compare different stages of the endometrial cycle. Here, the authors show a method for precisely determining endometrial cycle stage based on global gene expression that reveals remarkably synchronised daily changes for over 3,400 endometrial genes.

  • β-thalassemia is a prevalent genetic disorder causing severe anemia, with study of the underlying molecular defects impeded by paucity of suitable patient material. Here, the authors show that cellular model systems of βthalassemia can be used to identify new therapeutic targets and as screening platforms for new drugs and reagents.

  • Several parameters in the bone marrow (BM) niche regulate leukaemic stem cell status and disease progression. Here, the authors show that calcium-sensing receptor affects the location of acute myeloid leukaemia (AML) cells in the BM niche which influences self-renewal of leukaemic stem cells and AML development

  • The commercialization of DNA tagging is a growing trend that demonstrates the increasing practicality of this novel approach. This interdisciplinary technology is based on the distinctive characteristics of DNA as a molecule that can remain stable in varying environmental conditions and store data following appropriate preparation. Moreover, newly developed technologies could simplify DNA synthesis and the encoding of data within DNA. The implementation of DNA tagging presents distinctive benefits in comparison to conventional labelling techniques, including universal product code (UPC) barcoding, radio-frequency identification (RFID), quick response (QR) codes, and Bluetooth technologies, by surmounting the limitations encountered by these systems. The discourse pertains to extant DNA-tagging mechanisms along with prospective implementations in a wide range of domains, including but not limited to art, the metaverse, forensics, wildlife monitoring, and the military. The potential of DNA labelling in various contexts underscores the importance of continued research and development in this rapidly evolving field.

  • The study of Prebiotic Chemistry, and the closely related study of Astrobiology, is ultimately the study of our own point(s) of origin. Aiming to answer the questions of how, when, and where did the building blocks of life—i.e. biologically relevant organic molecules—form? With the imminent analysis of samples successfully returned from the near-Earth asteroid Bennu, and continuing discoveries from the Ryugu asteroid samples, the answers to some of these questions may be in sight.
