You are already at the latest version Ambient fine particulate matter of size less than 2.5 µm in aerodynamic diameter (PM2.5) is a key component of ambient air pollution that has been linked to numerous adverse health outcomes. Reliable estimates of PM2.5 are important for supporting epidemiologic and health impact assessment studies. Precise measurements of PM2.5 are available through networks of monitors, however these are spatially sparse and temporally incomplete.

AbstractExtrachromosomal DNA (ecDNA) is a major contributor to treatment resistance and poor outcome for patients with cancer1,2. Here we examine the diversity of ecDNA elements across cancer, revealing the associated tissue, genetic and mutational contexts. By analysing data from 14,778 patients with 39 tumour types from the 100,000 Genomes Project, we demonstrate that 17.1% of tumour samples contain ecDNA.

Pacific Gas & Electric has grabbed headlines in recent months for the huge rate increases that it claims are needed to pay for safety improvements to its system. Those increases are affecting Ava Community Energy customers, who pay Ava for electricity and pay PG&E to have it delivered. In fact, Ava customers pay twice as much to PG&E to have power delivered as they do for the electricity itself.

AbstractIn vitro models of autoimmunity are constrained by an inability to culture affected epithelium alongside the complex tissue-resident immune microenvironment. Coeliac disease (CeD) is an autoimmune disease in which dietary gluten-derived peptides bind to the major histocompatibility complex (MHC) class II human leukocyte antigen molecules (HLA)-DQ2 or HLA-DQ8 to initiate immune-mediated duodenal mucosal injury1,2,3,4.

AbstractThe contrast between the disruption of genome topology after cohesin loss and the lack of downstream gene expression changes instigates intense debates regarding the structure–function relationship between genome and gene regulation.
