“Don’t drink the water” might be good enough advice to keep you from getting sick in some places, but according to researchers from Arizona State and Drexel University, the admonition should probably be expanded to “…try not to breathe the water either.” In research recently published in the journal Environmental Science & Technology, the group […]Continue Reading ...
Analysis shows Hispanic communities are disproportionately exposed More than 5.6 million Americans are potentially exposed to nitrate in drinking water at levels that could cause health problems, according to a new study. In this first analysis of its kind, researchers found that water systems with higher nitrate levels also tend to serve communities with higher […]Continue Reading ...
Analysis of existing state and federal guidelines shows discrepancies in recommended safe levels of toxic contaminants PFOA and PFOS in drinking water In response to the growing problem of drinking water contaminated with per- and poly-fluoroalkyl substances (PFAS), a new analysis shows that many states are establishing their own guideline levels for two types of […]Continue Reading ...
Higher collective consumption of sweetened fruit drinks, soda, and water was associated with a higher likelihood of developing chronic kidney disease (CKD) in a community-based study of African-American adults in Mississippi. The findings, which appear in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN), contribute to the growing body […]Continue Reading ...
Dec 27 2018 Scientists at Stanford University have designed an electrocatalytic mechanism that works like a mammalian lung to convert water into fuel. Their research, published December 20 in the journal Joule, could help existing clean energy technologies run more efficiently. The act of inhaling and exhaling is so automatic for most organisms that it […]Continue Reading ...
An interview with James Flanaghan at SfN 2018, discussing the uses of DREADDs in neurobiological research and the advantages of water-soluble ligands. What are DREADDs? DREADDs are “Designer Receptors Exclusively Activated by Designer Drugs”. They are synthetic GPCRs which have been engineered to lack affinity for their endogenous ligands and to confer efficacy to an […]Continue Reading ...
Researchers at the Ecole Polytechnique Fédérale de Lausanne have discovered a new way to monitor electrical activity in nerve cells – by observing the behavior of water molecules surrounding neuronal membranes. Tatiana Shepeleva | Shutterstock Until now, the only way to monitor neuronal activity was to inject fluorophores into the brain region of interest or […]Continue Reading ...
The startup company Smartmedic and a team of researchers of Kaunas University of Technology (KTU), Lithuania developed a smart life-collar prototype which inflates once in contact with water thus keeping the head of its wearer above the surface. Buddy, the Life-Collar can be vital for parents of young children, who are still not confident in […]Continue Reading ...
Here’s to sipping a cupful of health: Green tea steeped in bottled water has a more bitter taste, but it has more antioxidants than tea brewed using tap water, according to new Cornell University food science research published in Nutrients. In tests conducted at Cornell’s Sensory Evaluation Center, consumers liked green tea brewed using tap […]Continue Reading ...
A new analysis shows variation in the way state and federal regulators manage PFAS contaminants in drinking water, with some states adopting guideline levels that are more health protective than the non-enforceable levels set by the U.S. Environmental Protection Agency (EPA). According to the study’s authors, the findings highlight the need for enforceable federal standards […]Continue Reading ...
Dec 18 2018 Rapid controlled transport of water droplets by sunlight-powered pump Driven by natural or artificial sunlight, a novel “microtube pump” transports water droplets over long distances. As reported by Chinese researchers in the Journal Angewandte Chemie, the pump consists of a tube whose properties can be changed asymmetrically through irradiation. This results in […]Continue Reading ...
While examining a skull from an ancient burial ground in a pre-Columbian village in Panama, Nicole Smith-Guzmán, bioarchaeologist at the Smithsonian Tropical Research Institute (STRI), was surprised to discover an example of surfers’ ear: a small, bony bump in the ear canal common among surfers, kayakers and free divers in cold climates. After inspecting more […]Continue Reading ...
A new study shows that fecal bacteria from sewage are living in far greater quantities in near-shore sediments of the Hudson River than in the water itself. The river’s pollution levels are generally monitored based on samples of clear water, not sediments, so the findings suggest that people stirring up the bottom while wading, swimming […]Continue Reading ...
Credit: CC0 Public Domain Hot water treatment may help improve inflammation and blood sugar (glucose) levels in people who are unable to exercise, according to a new study. The findings are published ahead of print in the Journal of Applied Physiology. Physical stress such as exercise can cause the short-term elevation of inflammatory markers. After […]Continue Reading ...
An inexpensive hydrogel-based material efficiently captures moisture even from low-humidity air and then releases it on demand. A simple device that can capture its own weight in water from fresh air and then release that water when warmed by sunlight could provide a secure new source of drinking water in remote arid regions, new research […]Continue Reading ...
