Malaria transmission is influenced by climate and land use/land cover change (LULC). This study examines the impact of climate and LULC on malaria risk in the Ecuadorian Amazon. Weekly malaria surveillance data between 2008 and 2019 from Ecuador's Ministry of Public Health were combined with hydrometeorological and LULC data. Cross-correlation analyses identified time lags. Bayesian spatiotemporal models estimated annual LULC rates of change (ARC) by census area and assessed the effects on and incidence. ARC for the five land cover classes (forest, agriculture, urban, shrub vegetation, water) ranged from -1 to 4% with agriculture increasing across areas. Forest and shrub vegetation ARC were significantly associated with both and . Temperature and terrestrial water content showed consistent negative relationships with both species. Precipitation had varying effects on (null) and (increase) incidence. Shrubs and forest expansion, increased temperature, and terrestrial water content reduced malaria incidence, while increased precipitation had varying effects. Relationships between malaria, LULC, and climate are complex, influencing risk profiles. These findings aid decision-making and guide further research in the region.

Although epidemiological studies have explored the association between poly- and perfluoroalkyl substances (PFAS) concentrations and semen quality, existing findings are often inconsistent. Our work aimed to explore the association of PFAS in plasma and semen with repeated measures of semen quality parameters in healthy adults. Plasma was collected at the initial recruitment and semen was collected at least once within five predetermined intervals during an approximately 3-month period.

Growing global population, escalating energy consumption, and climate change threaten future energy security. Fossil fuel combustion, primarily coal, oil, and natural gas, exacerbates the greenhouse effect driving global warming through CO emissions. To address such issues, research is focused on converting CO into valuable fuels and chemicals, which aims to reduce noxious CO and simultaneously bridge the gap between energy demands and sustainable supply.

The light-absorbing chemical components of atmospheric organic aerosols are commonly referred to as Brown Carbon (BrC), reflecting the characteristic yellowish to brown appearance of aerosol. BrC is a highly complex mixture of organic compounds with diverse compositions and variable optical properties of its individual chromophores. BrC significantly influences the radiative budget of the climate and contributes to adverse air pollution effects such as reduced visibility and the presence of inhalable pollutants and irritants.

Inclusive and supportive classroom environments are essential, particularly during political and societal crises such as wars, disinformation, polarization, and rising populism and extremism. While existing research underscores the importance of such environments, few studies comprehensively examine the impact of anti-hate speech prevention programs on classroom dynamics and students' social development. This study addressed this gap by investigating the direct and indirect effects of the HateLess anti-hate speech prevention program on inclusive classroom climate, classroom cohesion, empathy, and self-efficacy among adolescents.
