Wildfires burning across Canada and the Western United States are spewing smoke over millions of Americans – the latest examples of ashy haze becoming a regular experience, with health impacts far greater than scientists previously estimated.
Research Highlights Rapid Permafrost Thaw at Point Lay, Alaska
A team of scientists working with local residents has detailed the rapidly accelerating “catastrophic” permafrost thawing and infrastructure damage at the northern Alaska coastal community of Point Lay.
Why Alaska’s salmon streams are suddenly bleeding orange
Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on them—with no way to stop the process once it starts.
Goodbye colonoscopy? Simple stool test detects 90% of colorectal cancers
Scientists at the University of Geneva have created the first detailed catalogue of gut bacteria at the subspecies level, unlocking powerful new ways to detect colorectal cancer. By applying machine learning to stool samples, they achieved a 90% detection rate—nearly matching colonoscopies, but with far less cost and discomfort. This...
Climate Change Could Drastically Reduce Aquifer Recharge in Brazil
The global climate crisis could significantly impact the natural replenishment of Brazilian aquifers, reducing the groundwater supply across the country.
As Ice Melts, a New Island Emerges in Alaska
The Alsek Glacier in southeastern Alaska once encircled a small rocky mound known as Prow Knob.
Reindeer Grazing Can Mitigate the Impacts of Winter Climate Change on Forest Carbon Release
Winter climate change is affecting the carbon exchange of northern coniferous forests, but the response depends upon reindeer grazing, according to a new study from the University of Oulu.
Soil warming experiments challenge assumptions about climate change
Heating alone won’t drive soil microbes to release more carbon dioxide — they need added carbon and nutrients to thrive. This finding challenges assumptions about how climate warming influences soil emissions.
When Does Melting Ice Capsize? New Research Unearths Several Mechanisms
Findings offer innovative ways to improve weather forecasting, measure climate-change impacts.
Stress in the Strands: Hair Offers Clues to Children’s Mental Health
University of Waterloo study shows long-term stress levels may signal mental health risks in children with chronic physical illnesses and guide early intervention.
