Transportation noise linked to higher risk of major cardiac events

Living in areas with consistently higher levels of noise from transportation was associated with a significantly higher risk of major adverse cardiac events compared with living in quieter areas, according to a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Urban living may reduce risk of first-time stroke

While urban life is often associated with stress and pollution, living in more intensely developed neighborhoods may actually protect against stroke, a new University of Michigan study suggests.

Socioeconomic gaps shape vulnerability to air pollution mortality in Europe

Socioeconomic factors are widely recognized as potential modifiers of the relationship between air pollution and mortality, but the available evidence remains limited.

Microbial teamwork enables efficient breakdown of phthalate plastic pollutants

Plastic trash has reached the world's most remote locations, from the bottom of the Mariana Trench to the summit of Everest.

Scientists turn plastic waste into Parkinson’s drug levodopa using engineered bacteria

Researchers engineered a two-strain microbial system that converts PET-derived terephthalic acid into levodopa, overcoming key bottlenecks in transport and enzyme inhibition. The proof-of-concept process achieves high yields under mild conditions and demonstrates a potential route for upcycling plastic waste into valuable pharmaceuticals.

Biodegradable sanitary pads made from water hyacinth pass safety and absorbency tests in new study

Researchers developed a biodegradable sanitary pad using water hyacinth fibers and cotton, transforming an invasive aquatic weed into a sustainable absorbent material. Laboratory tests showed strong fluid absorption, safe pH levels, low microbial contamination, and rapid biodegradation.

Climate policy tradeoffs may reduce air quality gains and global health outcomes

A new study published in The Lancet Global Health reveals a previously underappreciated tension at the heart of international climate negotiations: policies designed to protect developing countries from bearing an unfair share of the cost of cutting carbon emissions could inadvertently deprive those same countries of millions of life-saving air quality improvements.

Global indicators identified to monitor health before pregnancy worldwide

The key health and social indicators needed for a new global system to monitor people's health before pregnancy have been identified for the first time by researchers at University College London and the University of Southampton.

Air pollution may be lowering global IQ and widening inequality, researchers warn

Researchers argue that exposure to fine particulate air pollution (PM2.5) may affect cognitive function and intelligence, potentially causing large population-level losses in global IQ. Using modelling based on published exposure–response data, the authors estimate that pollution could be associated with tens of billions of IQ points lost worldwide, with the largest impacts in lower-income regions.

How social and environmental exposures across life influence mental health risk

Researchers outline how the exposome framework, which captures the totality of environmental exposures across the lifespan, can help explain how non-genetic factors shape mental health risk and resilience. The perspective highlights how integrating environmental, biological, and social data could improve prevention strategies, research models, and personalized mental health care.

Using a smartwatch to detect changes in brain health

Can smartphones or smartwatches help detect early signs of neurological or mental illness? Researchers at the University of Geneva (UNIGE) monitored a group of participants wearing connected devices, and used artificial intelligence to analyze data such as heart rate, physical activity, sleep and air pollution.

How somatic mutations shape disease and reveal new drug targets

Researchers reviewed how somatic mutations accumulate in normal and diseased tissues, showing that natural selection can expand clones that influence disease risk, tissue adaptation, or cellular resilience. The study proposes somatic genomics as a powerful strategy to uncover disease mechanisms and identify new therapeutic targets across multiple conditions.

Building global standards for antimicrobial policy

Antimicrobial resistance (AMR) threatens human, animal, and environmental health globally. An international team from leading institutions, including the University of Edinburgh, London School of Hygiene and Tropical Medicine, North Carolina State University, and the International Centre for Antimicrobial Resistance Solutions, identifies fundamental gaps in current mathematical modelling approaches that prevent translation of science into policy, including data limitations, knowledge gaps about AMU-AMR relationships, and the absence of international coordination mechanisms similar to climate change efforts. They call for transdisciplinary collaboration to build integrated modelling architectures.

Researchers propose that Parkinson’s disease may start in the gut, not the brain

A perspective in The Journal of Clinical Investigation argues that environmental exposures may interact with the gut microbiome and intestinal barrier to trigger biological processes linked to Parkinson’s disease. The authors propose that cumulative environmental stressors can erode host resilience, promoting α-synuclein pathology, immune activation, and neurodegeneration.
