Researchers have created a simulation that maps underground water on a continental scale. The result of three years' work studying groundwater from coast to coast, the findings plot the unseen path that each raindrop or melted snowflake takes before reemerging in freshwater streams, following water from land surface to depths...
Method can detect harmful salts forming in nuclear waste melters
A new way to identify salts in nuclear waste melters could help improve clean-up technology, including at the Hanford Site, one of the largest, most complex nuclear waste clean-up sites in the world. Researchers used two detectors to find thin layers of sulfate, chloride and fluoride salts during vitrification, a...
Reducing irrigation for livestock feed crops is needed to save Great Salt Lake, study argues
The Great Salt Lake has lost more than 15 billion cubic yards of water over the past three decades, is getting shallower at the rate of 4 inches a year, and an analysis of its water budget suggests reducing irrigation is necessary for saving it.
Drug-resistant hookworms put pets and people at risk
Canine hookworms are becoming increasingly resistant to drugs across Australia, according to new research. Scientists have identified widespread resistance to benzimidazole-based dewormers which are commonly used to treat gastrointestinal parasites in dogs.
These 11 genes may help us better understand forever chemicals’ effects on the brain
A new study has identified 11 genes that may hold the key to understanding the brain's response to these pervasive chemicals commonly found in everyday items.
Lead pollution likely caused widespread IQ declines in ancient Rome, new study finds
Lead exposure is responsible for a range of human health impacts, with even relatively low levels impacting the cognitive development of children. Scientists have previously used atmospheric pollution records preserved in Arctic ice cores to identify periods of lead pollution throughout the Roman Empire, and now new research expands on...
Marked decrease in Arctic pressure ridges
In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges. These ridges are created when ice floes press against each other and become stacked, and are a characteristic feature of Arctic sea ice, an obstacle for shipping, but also an essential...
Floods linked to rise in US deaths from several major causes
Over the last 20 years, large floods were associated with up to 24.9 percent higher death rates from major mortality causes in the U.S. compared to normal conditions. A new study demonstrates the sweeping and hidden effects of floods --including floods unrelated to hurricanes, such as those due to heavy...
Climate extremes in 2024 ‘wreaking havoc’ on the global water cycle
2024 was another year of record-breaking temperatures, driving the global water cycle to new climate extremes and contributing to ferocious floods and crippling droughts, a new report shows. The report found rising temperatures are changing the way water moves around the planet, 'wreaking havoc' on the water cycle.
Scientists unveil surprising human vs mouse differences in a major cancer immunotherapy target
Much of our knowledge of the protein PD-1, a leading cancer treatment target, comes from studies in mice. In a comprehensive assessment of PD-1, researchers have found that PD-1 in mice is significantly weaker than the human version, providing new information on how cancer treatments are developed.
