The finding suggests urban planners and policymakers could offset some health damage from unavoidable air pollution by prioritizing tree cover and parks in city design.EN

Researchers are launching a major trial in Burkina Faso to measure whether reflective roof coatings reduce indoor temperatures, illness, and economic losses. If successful, the low-cost intervention could become a scalable climate adaptation for millions of Africans facing deadly heat with limited access to air conditioning.EN

Researchers discovered that individual human liver cells consume oxygen at vastly different rates depending on their size, and that cells clustered together actually reduce their metabolic activity. The finding could transform how companies develop artificial tissue models for drug testing and organ-on-a-chip technologies—making them far more accurate at predicting how drugs behave in real human bodies.EN

A major health assessment reveals that people living across the Arctic—particularly in Greenland, the Faroe Islands, and northern Canada—carry dangerously high levels of mercury and other metals in their bodies. While some regions show declining contamination trends, the exposure remains a significant public health concern that affects indigenous communities and could influence resource development policies.EN

A new analysis reveals that most countries lack standardized training programs in environmental health, leaving public health professionals ill-equipped to handle pollution, biodiversity loss, and climate impacts. Researchers propose retraining current workers using existing resources—a faster path than waiting for new graduates—to build the capacity needed for the global health transition.EN

A new framework calls for training practitioners across multiple disciplines to tackle interconnected threats from climate change, pollution, and biodiversity loss. Current public health approaches are inadequate, researchers argue, requiring urgent investment in capacity building to equip organizations and governments to respond effectively to mounting environmental challenges.EN

A 33-country analysis of 532 cities reveals that cardiovascular deaths spike in cold weather while respiratory deaths peak in heat—with risks varying sharply by age. The findings could reshape how cities design public health alerts and healthcare capacity planning as climate patterns shift.EN

A major review finds that sanitation and sewage systems emit far more greenhouse gases than previously tracked—but scientists lack standardized methods to measure them. The gap leaves policymakers and utilities flying blind on a major emissions source they need to address to hit climate targets.EN

A new study of three African protected areas reveals that conservation zones are pushing neighboring households into deeper poverty by increasing both wildlife attacks and climate exposure. The finding suggests conservation agencies must redesign policies to protect livelihoods alongside wildlife—or risk losing community support for parks entirely.EN

A new study challenges proposed bans on using trophy-hunted animal remains for conservation research, arguing that DNA samples from legally hunted species could provide critical data for managing endangered wildlife populations. The finding complicates ongoing policy debates over trophy imports and suggests blanket restrictions may sacrifice scientific tools needed to protect biodiversity.EN

Scientists tracked genetic changes in lake populations over decades using DNA preserved in sediment, revealing that nutrient pollution drives rapid evolution in aquatic species. The findings suggest ecosystems may adapt to human-caused changes faster than previously thought—but raise questions about whether adaptation can keep pace with accelerating environmental disruption.EN

A new analysis of Swedish forestry reveals that commercial forest management creates a substantial "carbon debt"—the difference between carbon stored in managed versus natural forests. This hidden deficit is so large it matches Sweden's total accumulated fossil fuel emissions, challenging the climate credentials of sustainable forestry practices and raising questions about how governments should count forest carbon in their climate strategies.EN

Researchers have identified how to optimize cooling systems on long-endurance surveillance aircraft, potentially extending mission duration and reducing weight. The finding could cut energy use in military aviation while improving operational capability—a meaningful efficiency gain for defense contractors and military planners facing rising fuel costs.EN
