A Cedars-Sinai analysis of its emergency department data found that visits for general illness, heart attacks and pulmonary illness rose sharply in the 90 days after the Eaton and Pacific Palisades fires began in January 2025, even as overall ER volume stayed roughly in line with prior years. Researchers said fine particles in wildfire smoke and stress could be contributing factors, and reported that abnormal blood test results linked to general illness more than doubled during the same period.
Mayo Clinic researchers have mapped a molecular circuit in alveolar type 2 lung cells that helps determine whether they rebuild tissue or fight infection. The study, published Oct. 14, 2025, in Nature Communications, suggests new paths for regenerative approaches in chronic lung conditions such as pulmonary fibrosis and COPD.
