Summary: There is growing evidence linking long-term exposure to fine particulate matter (PM2.5) with negative health impacts. However, the specific influence of individual components of PM2.5 on health risks remains unclear. In a cohort study conducted in the contiguous United States, researchers found that increased exposure to PM2.5 mass and its key compounds, including black carbon, organic matter, soil dust, nitrate, sulfate, and ammonium, were significantly associated with higher all-cause mortality in older adults. These findings suggest the importance of reducing fossil fuel burning for improved air quality and public health.

Summary: The emergence of immune-evading viral variants of SARS-CoV-2 raises concerns about relying solely on vaccines for managing the COVID-19 pandemic. A computational study suggests that transmission rate of intermediate mutants affects the appearance of new immune-evading variants. Vaccination can lower the emergence rate, but other interventions to reduce transmission can have a similar effect. Widespread and repeated vaccination alone is insufficient to prevent the emergence of novel immune-evading strains if transmission rates remain high.

Summary: SARS-CoV-2 vaccinations initially reduce severe disease and death, but neutralizing antibody (nAb) binding titers decrease due to PK waning and viral evolution. There is also heterogeneity in nAb response among individuals. A personalized booster strategy is proposed, considering individual differences in a PK/PD model to predict vaccinal protection variabilities. Viral evolution will reduce vaccinal protection, especially for individuals with less durable immune response. More frequent boosting may restore protection for those with weaker immune response. The ECLIA RBD binding assay predicts neutralization efficacy and could be a tool for assessing individual immunity. Vaccinal protection is not assured and a potential path forward for reducing risk to vulnerable individuals is identified.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
