Plastic pollution remains a major issue around the world, and now a new study suggests that microplastics have invaded our drinking water.

An investigation conducted by Orb Media and the University of Minnesota School of Public Health examined over 150 water samples from 14 countries across five continents — all in search of microfibers.

Sixteen years after the collapse of the World Trade Center towers sent a “cloud” of toxic debris across Lower Manhattan, children living nearby who likely breathed in the ash and fumes are showing early signs of risk for future heart disease.

Strontium (Sr) is an element which in the event of a nuclear accident is the one that is most released into the atmosphere. The chemical behaviour of strontium is similar to that of calcium and can accumulate in the soil, in plants and in animals (in bones, especially). It is an element with two main radioisotopes (90Sr and 89Sr) which have an effective biological life that is relatively high for human beings, and due to its fixation in the bones, ends up giving a dose of radiation over many years.

A plant-based, Mediterranean-style diet has been shown to provide the same medical benefits for treating laryngopharyngeal reflux as popular reflux medications. This is according to a study published today in JAMA Otolaryngology Head Neck Surgery by researchers from Northwell Health’s The Feinstein Institute for Medical Research and New York Medical College.

Positive emotions are often seen as critical aspects of healthy living, but new researchsuggests that the link between emotion and health outcomes may vary by cultural context. The findings, published in Psychological Science, a journal of the Association for Psychological Science, show that experiencing positive emotions is linked with better cardiovascular health in the US but not in Japan.

Researchers at the University of Waterloo have invented a fast, affordable way for developing communities to test their drinking water for potentially deadly E. coli.

Unlike current tests that cost about $70 and can take up to three days to get back from the lab, the Waterloo invention uses paper strips similar to those in litmus tests to produce results in less than three hours at a cost of 50 cents.

MIT and Harvard University researchers have engineered E. coli cells that can be used to study how bacteria at an infection site respond to antibiotic treatment, allowing scientists to learn more about how existing antibiotics work and potentially help them to develop new drugs.

In the new study, which appears in the Aug. 31 issue of Cell Host and Microbe, the researchers found evidence that some existing hypotheses about how bacteria respond to antibiotics are not correct.

UCLA biologists have developed an intervention that serves as a cellular time machine — turning back the clock on a key component of aging.

Researchers have developed the first tool that can diagnose Parkinson’s disease when there are no physical symptoms, offering hope for more effective treatment of the condition.

The Singapore Chinese Health Study reveals increased risk of diabetes with higher intake of red meat and poultry, partially attributed to the dietary iron content in these meats.
