Trapped sediment in dams "endangers" water supplies: UN
Thousands of the world's large dams are so clogged with sediment that they risk losing more than a quarter of their storage capacity by 2050, UN researchers said Wednesday, warning of the threat to water security......»»
Functionalized chitosan as a biobased flocculant for the treatment of complex wastewater
Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB have developed a biobased and functionalized flocculant to efficiently treat complex wastewaters. Furthermore, toxic phenols are removed from the water by the e.....»»
Ice shelves fracture under weight of meltwater lakes, study shows
When air temperatures in Antarctica rise and glacier ice melts, water can pool on the surface of floating ice shelves, weighing them down and causing the ice to bend. Now, for the first time in the field, researchers have shown that ice shelves don't.....»»
New eco-friendly lubricant additives protect turbine equipment, waterways
Scientists at the Department of Energy's Oak Ridge National Laboratory have developed lubricant additives that protect both water turbine equipment and the surrounding environment......»»
Precipitation may brighten Colorado River"s future, says modeling study
The Colorado River's future may be a little brighter than expected, according to a new modeling study from CIRES researchers. Warming temperatures, which deplete water in the river, have raised doubts the Colorado River could recover from a multi-dec.....»»
Improved AI process could better predict water supplies
A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and o.....»»
Sourdough under the microscope reveals microbes cultivated over generations
Sourdough is the oldest kind of leavened bread in recorded history, and people have been eating it for thousands of years. The components of creating a sourdough starter are very simple—flour and water. Mixing them produces a live culture where yea.....»»
An AI model to reduce uncertainty in evapotranspiration prediction
When scientists look at the Earth's available water for ecosystem services, they don't just look at precipitation. They must also account for water moving from the ground to the atmosphere, a process known as evapotranspiration (ET)......»»
New research reveals terahertz waves" impact on dynamics of nanoconfined water molecules
In a new discovery, researchers have revealed novel insights into the behavior of water molecules confined within nanostructures. Their study, published in Science Advances on April 24, delves into how terahertz (THz) waves influence the dynamics of.....»»
Researchers reveal water-assisted oxidative redispersion of metal nanoparticles
Oxidative redispersion at elevated temperatures has long been utilized in heterogeneous catalysis for the regeneration of sintered metal catalysts and the synthesis of metal single atom and cluster catalysts. These redispersion processes require a co.....»»
After iOS, the EU now has its Sights set on iPadOS
Apple's under fire once more. The post After iOS, the EU now has its Sights set on iPadOS appeared first on Phandroid. Apple’s in hot water (again) – following an investigation by the European Commission into the Cupertino tech.....»»
How did the early Great Barrier Reef manage rapid environmental change?
As the modern Great Barrier Reef emerged after the last ice age, it had to cope with multiple environmental stresses—rising sea levels, increased sediment from a flooding coastline, ocean turbulence and likely warming oceans......»»
Better reservoir management could aid food security and fisheries conservation in US
After nearly a century of people building dams on most of the world's major rivers, artificial reservoirs now represent an immense freshwater footprint across the landscape. Yet, these reservoirs are understudied and overlooked for their fisheries pr.....»»
Underwater mass spectrometry achieves 500-fold sensitivity enhancement for dissolved methane detection
A research team led by Prof. Chen Chilai from Hefei Institutes of Physical Science of Chinese Academy of Sciences, amplified the detection sensitivity of dissolved methane in water by over 500 times, surpassing 500-fold enhancement, thus reaching bas.....»»
Researchers achieve electrosynthesis via superwetting organic-solid-water interfaces
Chinese scientists have recently achieved the direct synthesis of high-purity benzaldehyde chemicals from the selective electrooxidation of benzyl alcohol. The organic-solid-water (OSW) three-phase reaction system has shown particular advantages in r.....»»
Study provides new global accounting of Earth"s rivers
A study led by NASA researchers provides new estimates of how much water courses through Earth's rivers, the rates at which it's flowing into the ocean, and how much both of those figures have fluctuated over time—crucial information for understand.....»»
Recovering phosphorus from sewage sludge ash to address problem of diminishing supplies of phosphorus ores
Valuable supplies of phosphorus could be recovered from sewage sludge ash, which remains after the sludge has been burned for electric power generation. The method has been developed by chemical engineers Yuuki Mochizuki and Naoto Tsubouchi at Hokkai.....»»
Amazon drops Apple"s M3 MacBook Air to record low $989
Apple's recently released M3 MacBook Air has dropped to an all-time low of $989 at Amazon while supplies last.The month-end $989 promotion applies to Apple's standard 13-inch MacBook Air with the M3 chip — and every color is eligible for the $110 i.....»»
Philippine settlement submerged by dam reappears due to drought
A centuries-old settlement submerged by the construction of a dam in the northern Philippines in the 1970s has reappeared as water levels drop due to a drought affecting swathes of the country......»»
Drinking water in low-income communities is more likely to be contaminated by "forever chemicals," research finds
PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University......»»
Managing meandering waterways in a changing world
Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean......»»
