Researchers used satellite data to analyze the impact of dust on snowmelt in the Colorado River Basin. The study found that dust-driven melting tends to peak earliest and be most intense in central-southern Rocky Mountains, accelerating spring melt rates by up to 1 mm water-equivalent per hour.
A collaborative effort investigates the Sikkim Himalaya flood, exploring its drivers, causes, and downstream impacts. The research aims to inform disaster risk reduction and build resilience in vulnerable regions.
The SUPERSLUG initiative aims to forecast the impact of sediment slugs on river catchments and communities. The project will use a range of sensors and numerical models to provide comprehensive predictions of where and how long-term effects might be felt, up to decades or centuries after an event.
A recent study by Brown University biologists reveals that even small variations in temperature and moisture can have massive impacts on tropical epiphyte species, threatening ecosystems they support. The research found that most species struggled to survive outside their native ranges in climate conditions differing from what they typ...
Researchers have identified cocaine as a contaminant of concern in the Bay of Santos' water, sediments, and marine organisms. The drug causes toxicological effects in animals such as mussels, oysters, and fish, with severe bioaccumulation and ecotoxicological risks.
Researchers found that streams with ample groundwater connections have greater microbial diversity and are more effective at preventing toxic metal entry. They also better detoxify existing metals.
Researchers found local rivers and streams to be the source of Salmonella enterica contamination after Hurricane Florence, contradicting assumptions about pig farms. The study has critical implications for disease control and prevention in coastal regions affected by tropical storms.
Researchers at KAUST discovered that certain combinations of stressors increase gene-transfer rates, while others reduce it. They found synergistic effects from combining stressors like UV light and disinfection chemical byproducts, as well as antagonistic effects from chloroform.
Scientists have identified thousands of non-coding genetic variants linked to Alzheimer's disease, focusing on their impact on microglial gene expression and function. The study found that turning off specific regions can affect multiple genes, highlighting the complex mechanisms underlying AD.
Researchers have identified a conserved brain region in vertebrates essential for initiating forward movement. The mesencephalic locomotor region (MLR) stimulates reticulospinal neurons to control finer details of movement. Mapping this circuit could lead to new treatments for Parkinson's disease.
A SUTD study has uncovered the reservoir filling strategies and operating rules of China's big hydropower dams on the Lancang-Mekong river. The data shows that dam operations remained steady during a severe drought, indicating no need for emergency releases to mitigate its impact.
Higher elevation mountain forests are using more water on average during droughts, reducing water availability downstream for cities and wildlife. Researchers found that these forests tend to be located above 3,280 feet and have increased water use due to rising temperatures and changes in tree species composition.
A new study by the University of Arizona has identified a brain region and neural circuitry that mediate satiation, making it possible to create treatments with fewer side effects for eating disorders and weight management. The parasubthalamic nucleus plays a key role in regulating feelings of fullness after eating.
The study found that misexpression of Tbx4 in the forelimb region leads to leg-like structures, while misexpression of Tbx5 in the hindlimb region results in wing-like structures. These findings suggest that Tbx4 and Tbx5 play crucial roles in determining fore- and hindlimb identity.
