Exposure to fire smoke—which can be composed of particulate matter, gases, materials from buildings such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), toxic metals, and carcinogenic compounds—may alter the immune system on a cellular level, according to a new study led by researchers at Harvard T.H. Chan School of Public Health.

A new Stanford-led study finds that controlled, low-intensity fires known as prescribed burns can slash wildfire intensity and dangerous smoke pollution across the western United States.

The risk of death spikes when people are exposed to both elevated levels of fine particulate matter from wildfire smoke and temperatures above 26 C, new UBC research has found.

The UK Pollinator Monitoring Scheme (PoMS), which engages thousands of citizen scientists to record insects on surveys across the UK countryside and gardens, is emphasising the value of having a wide range of plants and habitats to support a diverse range of pollinators.

Emily Williams, an ecologist at the UK Centre for Ecology & Hydrology, discusses a project to tackle invasive non-native species on the Falkland Islands, which included a recent visit to share knowledge with local experts.

While emerging evidence suggests pesticides can be toxic to the mix of microorganisms in the digestive system, a new study is the first to map changes to specific gut bacteria based on interactions between human microbes and insect-killing chemicals observed in the lab and an animal model.

Antibiotic-resistant bacteria pose a growing threat to food crops and livestock, but promising new methods to destroy them are being introduced by a synthetic biology researcher at Flinders University, who has been awarded a prestigious ARC Laureate Fellowship.

A major discovery by an interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has found a safer and more sustainable approach to extract and recover gold from ore and electronic waste.

A new study challenges recent claims about dramatic “greening” in Antarctica and how this conflicts with decades of field-based ecological knowledge.

From New York to Paris to Beijing, urban trees are enjoying an extra-long growing season, a new study finds.
