Chrome Plating Facility Siting Is Associated with Neighborhood Demographic and Socioeconomic Factors and Elevated Per- and Polyfluoroalkyl Substances in Blood in California.

Chrome plating facilities release toxic chemicals, including perfluoroalkyl and polyfluoroalkyl substances (PFAS), disproportionately affecting nearby neighborhoods. We analyzed census-tract-level demographic and socioeconomic data using the American Community Survey (2018-2022) alongside 2019 data on chrome plating facilities from the California State Water Board. Two cohorts were included: adolescents from the Study of Latino Adolescents at Risk of Type 2 Diabetes (SOLAR; = 238; recruited between 2001 and 2012) and young adults from the Metabolic and Asthma Incidence Research study (Meta-AIR; = 118; 2014-2018).

Machine Learning Scoring Reveals Increased Frequency of Falls Proximal to Death in Drosophila melanogaster.

Falls are a significant cause of human disability and death. Risk factors include normal aging, neurodegenerative disease, and sarcopenia. Drosophila melanogaster is a powerful model for study of normal aging and for modeling human neurodegenerative disease.
