UC Irvine researchers create E. coli-based water monitoring technology
University of California, Irvine

Irvine, Calif., Feb. 23, 2023 – People often associate Escherichia coli with contaminated food, but E. coli has long been a workhorse in biotechnology. Scientists at the University of California, Irvine have demonstrated that the bacterium has further value as part of a system to detect heavy metal contamination in water. E.

   
Newswise: Enhanced Arsenic Detection in Water, Food, Soil

Enhanced Arsenic Detection in Water, Food, Soil
American Institute of Physics (AIP)

In Journal of Applied Physics, a team of scientists fabricate sensitive nanostructured silver surfaces to detect arsenic, even at very low concentrations. The sensors make use of surface-enhanced Raman spectroscopy: As a molecule containing arsenic adheres to the surface, it's hit with a laser and the arsenic compound scatters the laser light, creating an identifiable signature. The technique is a departure from existing methods, which are time-consuming, expensive, and not ideally suited to on-site field assays.

UNH Research Finds Well Water Risks More Detectable During Warmer Weather
University of New Hampshire

Over 44 million people in the United States depend on private drinking water wells that are not federally regulated. Researchers at the University of New Hampshire and collaborating institutions found that current monitoring practices do not accurately reflect groundwater pollution risks because spikes in harmful bacteria, like those from animal and human waste, vary depending on the season—with highest levels observed from testing conducted in summer months when temperatures are over 90°F.

The environmental benefits of a food-sharing economy are highly dependent on how the money saved is then used
Tel Aviv University

Does the digital sharing economy really reduce harm to the environment? The researchers found that food sharing has significant environmental advantages, but that a substantial part of the benefits of online sharing platforms are offset due to the use of the saved money for purposes that are not necessarily green.

Artificial sweetener as wastewater tracer
University of Vienna

Acesulfame is a sweetener in sugar-free drinks and foods. As it cannot be metabolised in the human body, the sweetener ends up in wastewater after consumption and remains largely intact even in sewage treatment plants. A new study by the University of Vienna shows that the persistence of the sweetener varies with temperature as the concentration of the sweetener in wastewater varies with the seasons.

This loofah-inspired, sun-driven gel could purify all the water you’ll need in a day
American Chemical Society (ACS)

Devices currently in development that clean up dirty water using sunlight can only produce a few gallons of water each day. But now, researchers in ACS Central Science report how a sunlight-powered porous hydrogel could potentially purify enough water to meet daily needs — even when it’s cloudy.

Mount Sinai Researchers Awarded $12 Million NIH Grant to Create a Center to Unravel Novel Causes of Food Allergy and Atopic Dermatitis
Mount Sinai Health System

Mount Sinai researchers have been awarded $12 million over five years by the National Institutes of Health to create a center to elucidate novel causes of, and contributing factors to, food allergies and atopic dermatitis. The Systems Biology of Early Atopy (SunBEAm) Analysis and Bioinformatics Center intends to develop a better understanding of allergy development. The center will apply systems biology to identify early-life markers of risk for food allergies and atopic dermatitis (also known as eczema), as well as biological pathways underlying these common conditions, through the profiling and analysis of longitudinal multi-omics data from a multi-center pre-birth cohort of 2,500 children.

Dollar Stores Are Growing as Food Retailers in the U.S.
Tufts University

Tufts University researchers have found that dollar stores are now the fastest-growing food retailers in the contiguous United States—and have doubled their share in rural areas. Households with more purchases at dollar stores also tend to be lower-income and headed by people of color.
