New tool to help decision makers navigate possible futures of the Colorado River
The Colorado River is a vital source of water in the Western United States, providing drinking water for homes and irrigation for farms in seven states, but the basin is under increasing pressure from climate change and drought. A new computational t.....»»
Better than blood tests? Nanoparticle potential found for assessing kidneys
In a study published July 29 in Advanced Materials, University of Texas at Dallas researchers found that X-rays of the kidneys using gold nanoparticles as a contrast agent might be more accurate in detecting kidney disease than standard laboratory bl.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Saturday Citations: Football metaphors in physics; vets treat adorable baby rhino"s broken leg
This week, researchers reported an effective way to protect working dogs from heat stress: training them to dunk their heads in cool water. A new computational technique provided a breakthrough in understanding the so-called "pseudogap" in quantum ph.....»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Scientists study how to increase water, nutrient-use efficiency in greenhouses, nurseries
Tom Fernandez, an MSU professor in the Department of Horticulture, has spent much of his 25-year career at MSU studying how to effectively manage water in greenhouses and nurseries to increase water-use efficiency and reduce nutrient runoff......»»
Forever chemicals persist through waste incineration, researcher finds
PFAS, often called "forever chemicals," present in municipal solid waste can survive the high temperatures of waste incineration and continue to spread into the environment via residues from waste-to-energy plants......»»
Schottky junction catalysts boost hydrogen production with non-precious metals in water electrolysis
Electricity-driven water electrolysis has garnered notable attention as an environmentally friendly method for hydrogen production, with high-purity hydrogen being crucial for addressing the energy crisis. Nonetheless, water electrolysis hydrogen evo.....»»
Location, location, location: Snowpack storage and runoff timing in burn scars depend on site and terrain
Increasingly severe wildfires at high elevations are impacting snowpack—an important reservoir for the U.S. West. The altered landscape makes it more challenging to predict when snow will melt and how much water will be available for use......»»
Nanoparticle-based remediation of chromium-contaminated water shows high efficiency
Groundwater is an essential source of drinking water across the country. However, heavy metal contamination in groundwater presents a significant health hazard. Researchers at the Indian Institute of Science (IISc) have developed a nanomaterial-based.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
Advances in hydrogen research: More efficient isotope separation in sight
The lightest of all elements, hydrogen, is in great demand due to its promising role as a sustainable resource in the energy transition. A team from Leipzig University and TU Dresden, as part of the Hydrogen Isotopes 1,2,3H Research Training Group, h.....»»
Detailed model suggests organic matter on Mars was formed from atmospheric formaldehyde
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually life. In their quest to answer the burning question about life on Mars.....»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»
The Outrageous Scheme to Capture and Sell Greenland’s Meltwater
A startup says shipping meltwater from Greenland’s glaciers internationally will boost the local economy and could help ease water pressures in arid regions—but what does that actually mean for the world?.....»»
Harnessing nature"s rhythm: Piezocatalysis for organic pollutant degradation
With the rapid growth of industrial and agricultural activities, water bodies are increasingly contaminated with harmful organic pollutants such as dyes, antibiotics, and bisphenol A. Traditional methods like adsorption, chemical treatments, and biol.....»»

South Africa"s Gauteng province launches water data hub, so residents can now keep track of shortages and repair issues
South Africa is a water-scarce country. In other words, it has an excess of demand over available supply. It also has low water security—the ability to ensure sustainable access to good quality water. The country's economic hub and biggest populati.....»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
