A paper published in Nature in September suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

Explore 13 cell types in mouse embryo lungs through single-cell multiomics! CTCF emerges as crucial in lung morphogenesis & progenitor maintenance! PMID:41315351, Nat Commun 2025, @NatureComms https://doi.org/10.1038/s41467-025-65757-1 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Single-cell multiomics analysis reveals CTCF as a key regulator of lung morphogenesis and progenitor maintenance | Nature Communications
Lung development generates a complex tree-like architecture through proximal-distal patterning and branching morphogenesis. However, the gene regulatory programs governing embryonic lung development remain poorly understood. Here, we present a comprehensive single-cell multi-omics atlas of mouse embryonic lungs, integrating gene expression and chromatin accessibility profiles. Through systematic analysis, we identify 13 distinct cell types and map cis-regulatory elements, peak-to-gene linkages, and transcription factors underlying lung development. Leveraging this multi-modal dataset, we uncover lineage-determining transcription factors driving cell differentiation, including the Activated Protein-1 complex. We further delineate gene regulatory networks involving diverse transcription regulators, including CCCTC-binding factor (CTCF). Using the Ctcf conditional knockout mouse, coupled with histological and multi-omics analyses, we demonstrate that CTCF orchestrates lung progenitor main
