Constructed wetlands do a good job in their early years of capturing carbon in the environment that contributes to climate change – but that ability does diminish with time as the wetlands mature, a new study suggests.
Fuel for California Fires
When hurricane-force winds whipped through Los Angeles County in early January 2025, the hills had ample fuels available to feed a wildland fire.
Ventilation in hospitals could cause viruses to spread further, study finds
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.
Low-level traffic air pollution linked to liver damage and fatty liver disease
Low levels of traffic-related air pollution harms the liver and may raise the risk of metabolic-associated fatty liver disease, a new study in mice suggests.
Ancient DNA analyses bring to life the 11,000-year intertwined genomic history of sheep and humans
The rise of pastoralist peoples in the Eurasian steppes and their westward spread some 5,000 years ago may have been fueled by sheep herding and people exploiting their milk. As early as 8,000 years ago the team found evidence that farmers were deliberately selecting their flocks -- for example, for...
Polar bear population decline the direct result of extended ‘energy deficit’ due to lack of food
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.
Antibody treatment prevents severe bird flu in monkeys
The antibody targets a stable part of the bird flu virus, ensuring that the immune protection can resist new variants and offer long-term protection against the globally spreading airborne infection.
Optical Fiber Sensor Provides Simple and Sensitive Detection of Arsenic in Drinking Water
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.
New Atom-Based Thermometer Measures Temperature More Accurately
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.
Otago Scientists Discover Antarctic Fast Ice Secrets
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.
