According to a 2017 Pew Research Study, 44% of adults in America say that they do not feel informed enough about science to understand news and new discoveries discussed on the media (Funk et al. 2019). This is concerning, because adults are not just passive consumers of media; among other...
Emerging data showing the presence of atmospheric microplastics (MPs) has recently raised awareness surrounding the potential of human nanoplastics (NPs) exposure. Due to factors such as weathering, UV exposure, and other biodegradation processes, plastic pollution in the environment breaks down over time into micro (<5 micrometers) and nanoscale (<1000nm) particles....
Congenital myopathies are caused by heritable mutations in particular genes. Genes mutated in congenital muscular dystrophies often encode cytoskeletal proteins, which contribute to the shape and movement of cells. We would like to know how such molecular defects lead to the muscle weakness in patients. It is therefore important to...
The aryl hydrocarbon receptor (AhR) has recently been described as a novel therapeutic target, given the potent suppression of multiple immune-mediated diseases following activation by the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In the parent-into-F1 graft-versus-host (GVH) model, suppression of the cytotoxic T-lymphocyte (CTL) response is associated with the presence of CD25⁺CTLA-4⁺IL-10⁺Foxp3[superscript...
Weyerhaeuser's Paper Mill in Albany, Oregon has been experiencing frequent ring formation in the #3 rotary lime kiln.
