Determining the causes of the 1931 Yangtze River Deluge
In the summer of 1931, an unprecedented calamity unfolded along the Yangtze River basin in eastern China—the 1931 Yangtze River flood, known as one of history's deadliest natural disasters. This cataclysmic event submerged a staggering 180,000 km2,.....»»
Colorado River Basin ranks among the world"s most water-stressed regions, analysis finds
A research effort tracking water scarcity around the world shows California, Arizona and other Western states are experiencing water stress at high levels similar to arid countries such as Saudi Arabia and Qatar......»»
This sure looks like the movements of a glacier across ancient Mars
It is a scientific certainty that Mars was once a much different place, with a denser atmosphere, warmer temperatures, and where water once flowed. Evidence of this past is preserved in countless surface features, ranging from river channels and allu.....»»
Scientists find "concerning" flaw in malaria diagnostics
Current methods can vastly overestimate the rates that malaria parasites are multiplying in an infected person's blood, which has important implications for determining how harmful they could be to a host, according to a new report......»»
Using glowing fish to detect harmful pesticides
Birth defects related to chromosomal abnormalities often stem from exposure to chemicals early in the mother's life. But determining which chemicals are at fault poses a serious challenge—akin to solving a hit-and-run case, decades after the fact......»»
Researchers develop a unique quantum mechanical approach to determining metal ductility
A team of scientists from Ames National Laboratory and Texas A&M University developed a new way to predict metal ductility. This quantum-mechanics-based approach fills a need for an inexpensive, efficient, high-throughput way to predict ductility. Th.....»»
Researchers seek to determine climate drivers of early human interbreeding
A new study published in the journal Science by an international team finds that past changes in atmospheric CO2 and corresponding shifts in climate and vegetation played a key role in determining when and where early human species interbred......»»
Novel socio-environmental vulnerability index pinpoints sustainability issues in Brazilian river basins
Brazilian researchers combined environmental physical, social and economic indicators to create an index that measures a region's vulnerability and used it to analyze the basins of the Parnaíba River and São Francisco River in the Northeast of Braz.....»»
Recovery of biodiversity in rivers across Europe is slowing down, study finds
The study, led by the Senckenberg Institute and published in the journal Nature, examined invertebrate biodiversity in river systems across 22 European countries and found that additional measures are needed to revive the recovery of freshwater biodi.....»»
Beaver-like dams can enhance existing flood management strategies for at-risk communities, study finds
River barriers made up of natural materials like trees, branches, logs and leaves can reduce flooding in at-risk communities by storing water upstream, new research has found......»»
Adapting to water temperature changes: The smart "coat" of the Yangtze finless porpoise
Cetaceans, including dolphins and whales, spend their entire lives in the water. Unlike terrestrial animals, they face greater challenges in regulating their body temperature because water conducts heat 25 times faster than air. However, these clever.....»»
Paris Olympics swimming test event in Seine canceled due to pollution
Excessive pollution in Paris' Seine River forced organizers to cancel a pre-Olympics test swimming competition due to take place on Sunday, the sport's international federation said......»»
Olympic swimming in the Seine highlights efforts to clean up city rivers worldwide
One year out from the 2024 Summer Olympic and Paralympic games, Paris has announced it will reopen the River Seine for swimming competition and then allow public swimming, ending a century-long ban. This ban was in place to stop people immersing them.....»»
DNA decodes the dining preferences of the shell-shucking whitespotted eagle ray
With mighty jaws and plate-like teeth, the whitespotted eagle ray (Aetobatus narinari) can pretty much crunch on anything. In fact, hard clam farmers in Florida's Indian River Lagoon have considered this species a threat to their production efforts a.....»»
Watch SpaceX test new water deluge system for Starship launches
SpaceX has released dramatic footage showing the testing of a new water deluge system designed to limit the damage caused by its Starship rocket at launch......»»
Researchers find evolutionary adaption in trout of Wyoming"s Wind River Mountains
The lakes in Wyoming's Wind River Mountains historically didn't contain fish, but stocking of trout that began in the early 1900s has created an environment in which hundreds of those lakes now have strong fish populations—some carried on by natura.....»»
Rio Pará found to contribute high trace metal concentrations to the Amazon estuary
The Amazon River is the largest river in the world. It discharges about one fifth of global freshwater runoff, resulting in a freshwater plume rich in nutrients and trace elements entering the Atlantic Ocean......»»
Researchers use quantum circuit to identify single nucleotides
DNA sequencing technology, i.e., determining the order of nucleotide bases in a DNA molecule, is central to personalized medicine and disease diagnostics, yet even the fastest technologies require hours, or days, to read a complete sequence. Now, a m.....»»
The Mystery of the Colorado River’s Missing Water
Snow is falling—but it doesn’t show up to replenish the river. In a drying West, researchers are racing to find out where it goes......»»
Billions in conservation spending fail to improve wild fish stocks in Columbia Basin
Four decades of conservation spending totaling more than $9 billion in inflation-adjusted tax dollars has failed to improve stocks of wild salmon and steelhead in the Columbia River Basin, according to Oregon State University research......»»
Groundwater pollution remains elevated in River Ythan catchment but on track for recovery: Study
Groundwater nitrate levels in the River Ythan catchment continue to breach environmental limits in some areas and pose a threat to local wildlife in the Ythan estuary, a new study has found......»»
