Certain flavorings used in electronic cigarette liquids may alter important cellular functions in lung tissue, according to new research presented at this year’s American Thoracic Society International Conference. Researcher Temperance Rowell, from the University of North Carolina at Chapel Hill, said the observed changes in cell viability, cell proliferation, and calcium signaling was flavor-dependent. “The […]
A study appearing in the latest issue of Cell Reports suggests that grass plants can bind, uptake, and transport infectious prions. The researchers, from The University of Texas Health Science Center at Houston, say that plants may play an important role in environmental prion contamination. Prions are protein-based infectious agents responsible for a group of […]
Scientists from the University of Leeds (UK) have discovered that airborne germ counts are 27 times higher around air dryers in comparison with the air around paper towel dispensers. Their study, published in theJournal of Hospital Infection, shows that both jet and warm air hand dryers spread bacteria into the air and onto users and […]
Despite the ban on lead in gasoline, blood lead levels in African nations have remained stubbornly high. Now, researchers from Ashland University think they might know why. According to their tests, cookware made in Africa from recycled metals is leaching lead into food in quantities nearly 200 times the levels permissible in the United States. […]
Scientists have found that for laboratory rats with human breast tumors, exposure to dim light at night made the tumors resistant to the breast cancer drug tamoxifen. The new findings, appearing in the journal Cancer Research, are the first to show that a significant correlation exists between melatonin levels and the effectiveness of tamoxifen. “Resistance […]
An imbalance of female sex hormones among men in Western nations may be contributing to high levels of male obesity, say researchers from the University of Adelaide. In a paper published in PLOS ONE, the researchers suggest that obesity among Western men could be linked with exposure to substances containing the female sex hormone estrogen […]
Outbreaks of Legionnaire’s disease are most often linked to large-scale air conditioning systems, but new research shows that automobile windshield washers can harbor the Legionella bacteria for long periods and release potentially dangerous numbers of these bacteria into the air. The findings, presented yesterday at the annual meeting of the American Society for Microbiology, suggest […]
A detailed new study into global food supplies confirms for the first time what experts have long suspected: human diets around the world have grown ever more similar and the trend shows no signs of slowing, with major consequences for human nutrition and food supply reliability. “More people are consuming more calories, protein and fat, […]
A stressful workplace can dramatically change gene expression in our immune system and significantly impact our health, say Ohio State University scientists in the journal Proceedings of the National Academy of Sciences. Study co-author John Sheridan said that although the mind-body health connection is well established, the inner workings of that association are still not […]
