Cannabis poisoning is soaring among small children as parents inadvertently leave edibles within their kids’ reach. Our expert explains how to childproof your pot. As marijuana has become legal in more states across the U.S., a recent analysis has found that the drug is accidentally ending up in the hands—and mouths—of children.
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.
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.
The size, strength and makeup of people’s social networks are key indicators of how they will respond to the health consequences of an environmental disaster, according to a new Cornell University study that focused on the Flint, Michigan water crisis.
Advancing food science for public health benefit through transparency and collaboration.
Georgia Institute of Technology researchers have found a way to use small shocks of electricity to disinfect water, reducing energy consumption, cost, and environmental impact. The technology could be integrated into the electric grid or even powered by batteries.
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.
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.
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.
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.
U.S. is lacking in the strict regulations for commercially produced baby foods that parents might expect, according to research team that outlined risk prevention strategies for parents and health care professionals.
Food manufacturers can now enter data on the safe, live microbes in their products into a global database to support a recommended amount for the diet.
Two new publications make it easier to formulate fiber-added foods with acceptable consumer tolerance.
A faculty member of Chulalongkorn University’s Faculty of Science has researched and developed high-protein, gluten-free pasta noodles for gluten-intolerant health-lovers.
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.
