A New Way to Produce Ammonia More Efficiently
Ammonia is used in fertilizer and many industrial processes.
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...
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.
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.
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.
Climate Change is Altering Nitrogen Composition in Arctic Rivers
Research shows shifting composition threatens marine ecosystems and highlights water quality impacts of global warming.
