Researcher Explores the Role of Native Plants in Mitigating Road Salt Pollution

Salt pollution caused by the application of road salts has emerged as a critical environmental issue which results in significant amounts of sodium and chloride infiltrating freshwater ecosystems, causing detrimental effects on ecology.
Researchers are investigating the implications of salt contamination on both native and non-native plant species within urban green infrastructures.
Recent research led by Megan Rippy, Assistant Professor in Civil and Environmental Engineering, investigates the dynamics between salt pollution and plant resilience within urban stormwater systems.
Preliminary findings from Rippy’s research indicate that the salinity levels within basins can be detrimental to plant health.
Of the 255 plant species examined across various detention basins in Northern Virginia, only a small fraction were identified as salt-tolerant indicating the challenge of utilizing plant communities as a primary means of mitigating salt pollution.
Quantitative measurements taken throughout the study showed that even in highly populated cattail areas, the biomasses from these plants could only eliminate a mere 5 to 6 percent of the total road salt applied during the winter months.
Phytoremediation may present a potential avenue for salt management but it is not a standalone solution. Comprehensive and integrated approaches are essential to effectively tackle salinity challenges.
Megan Rippy’s work emphasizes the significance of integrating plant health into the design and maintenance of stormwater management infrastructures.
Researchers have an opportunity to influence future innovations in environmental policy and urban design, harmonizing human needs with ecological integrity for generations to come.

NSP4 Protein from Rotavirus Influences Severity of Gastrointestinal Diseases

Scientists have discovered that NSP4, a protein produced by rotavirus, is a critical element in how the virus causes gastroenteritis and other illnesses, particularly in children.
The NSP4 protein interacts with both cells that have been infected and non-infected neighbouring cells. The disruptions that this causes to calcium signalling in the cells is directly linked to the severity of the rotavirus infection.
The researchers believe that if they learn how to interfere with NSP4's disruption on calcium signalling then preventative and treatment strategies may be developed.
Rotavirus causes 25% of severe cases of acute paediatric gastroenteritis, with its symptoms including abdominal pain, fever, vomiting, and watery diarrhoea.
In experiments with attenuated and virulent strains of rotavirus, researchers have shown that NSP4 is solely responsible for generating calcium waves that are observed during the natural infection.
The study demonstrated that there is a significant difference in the amount and intensity of calcium signals generated in the cells by NSP4 between the virulent and the attenuated types of rotavirus.
The more intense calcium signal was related to the virulent version while the weakened symptom one associated with attenuated strains.
The research explains how the calcium signalling caused by NSP4 can serve as a manipulation mechanism for the virus to allow it to replicate and survive.
Researchers believe that this breakthrough understanding of NSP4's impact will enable the development of impactful and effective strategies for fighting rotavirus.
The study is the result of collaboration between various institutions, including Indiana University and Stanford University School of Medicine, and with the support of National Institutes of Health grants.
