WHO reports measurable health gains but warns of unmet goals

The World Health Organization (WHO) today released its Results Report, highlighting measurable improvements in people's health worldwide in 2025, despite funding cuts affecting both the organization and the broader global health sector.

Air quality in infancy may fundamentally shape long-term immune development

Ambient air pollution is associated with respiratory infection burden in the first year of life, according to preliminary findings from the Immune Development in Early Life (IDEaL) Rome Cohort. Findings from the cohort will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.

Microplastics in the liver may drive global liver disease rates

There is considerable evidence that microplastics and nanoplastics are present in the livers of humans, and wild animal populations on land and in the ocean.

Study links common herbicide to rising early-onset colorectal cancer risk

Researchers used DNA methylation-based “epigenetic fingerprints” as proxies for lifelong exposome-related patterns and found that early-onset colorectal cancer was associated with lower Mediterranean diet adherence, lower education, smoking-related signatures, and higher picloram-related exposure signals. They then supported the picloram association in nine independent cohorts and with 21 years of US county-level pesticide-use data, while noting that the findings show association rather than proof of causation.

Chronic wildfire smoke exposure may raise long-term cancer risks

Exposure to wildfire smoke was associated with a significantly increased risk of lung, colorectal, breast, bladder, and blood cancer, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Long-term exposure to air pollution (PM2.5) raises risk of developing cancer by 11 % and of dying from cancer by 12 %

The Union for International Cancer Control (UICC), with support from the Clean Air Fund, has released a global report, Clean air in cancer control: An overview of the evidence, presenting data on the scale of cancer risk and mortality from polluted air.

Climate change could make humidity-driven heat risks more dangerous, study finds

Researchers analyzing 2.46 million ambulance dispatches across 13 Chinese cities found that humidity can intensify the health risks linked to both hot and cold temperatures, with cold-dry and warm-wet conditions posing the greatest risks. Future climate projections suggest compound temperature-humidity events will become more frequent and increasingly shift health burdens toward heat-related events in China.

Short-term and cumulative exposure to air pollution tied to increased migraine activity

Air pollution is associated with increased migraine activity, according to a study published on April 15, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Microplastics lab studies may fail to reflect real-world exposure

Microplastics pose health risks, but lab studies often fail to reflect real-world exposure, highlighting critical gaps in toxicological research methodologies.

Pennsylvania town faces fallout from Trump's environmental rule rollback

North America's largest coke plant hugs the west bank of Pennsylvania's Monongahela River, belching out emissions from turning superheated coal into a carbon-rich fuel.

Europe faces growing health threats from fossil fuel reliance

Europe's dependence on fossil fuels is not only making the continent economically and politically vulnerable, it also has dramatic consequences for the population's health.

Large-scale exposome research shows how multiple factors influence disease risk

For decades, scientists have been carefully unraveling the role of genes in disease by examining how small variations in a person's genetic code can shape lifelong risk of developing common conditions such as cancer, diabetes, or heart disease.

Study reveals bile as reservoir for microplastics in humans

Plastic pollution has become one of the defining environmental issues of modern life, and microplastics are now known to enter the body through food, drink, and air.

Living near Salton Sea linked to reduced lung growth in children

Children who live within 11 kilometers of the Salton Sea, a drying body of water with a high concentration of salts and contaminants in Imperial Valley, California, have slower lung function growth between ages 10 and 12 than children who live farther away.
