Plumes of wildfire smoke can carry contaminants hundreds of kilometres, leaving a lingering toxic footprint that has the potential to be re-released into the environment, McMaster researchers show.

Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around more, according to a new study from researchers at UCL and UCLH.

Traffic-related air pollution harms the liver and may raise the risk of metabolic-associated fatty liver disease, a new study in mice suggests.

Turning environmental waste into useful chemical resources could solve many of the inevitable challenges of our growing amounts of discarded plastics, paper and food waste, according to new research. 

Ōtākou Whakaihu Waka scientists have successfully analysed more than 30 years of vital data on the thickness of landfast sea ice in Antarctica’s McMurdo Sound, which will prove useful to measure future impacts of climate change.

Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal. 

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. 

U of T Scarborough researchers have directly linked population decline in polar bears living in Western Hudson Bay to shrinking sea ice caused by climate change.

Scientists from the University of Cambridge and British Antarctic Survey have used ice core records to draw new conclusions about how Antarctica was affected by increased global temperatures over 100,000 years ago.

An international research team has concluded that the Sikkim flood disaster in the Himalayas in October 2023 was caused by some 14.7 million cubic meters of frozen moraine material collapsing into South Lhonak Lake, triggering a 20-meter flood wave.
