People who apply eyeliner on the inner eyelid run the risk of contaminating the eye and causing vision trouble, according to research by a scientist at the University of Waterloo. This is the first study to prove that particles from pencil eyeliner move into the eye. Dr. Alison Ng, at the Centre for Contact Lens […]

How Manuka Honey Helps Fight Infection

how-manuka-honey-helps-fight-infection-1024w

Manuka honey may kill bacteria by destroying key bacterial proteins. Dr Rowena Jenkins and colleagues from the University of Wales Institute – Cardiff investigated the mechanisms of manuka honey action and found that its anti-bacterial properties were not due solely to the sugars present in the honey. The work was presented this week (7-10 September […]

Red Squirrels In The British Isles Are Infected With Leprosy Bacteria

Microbiologists at EPFL and the University of Edinburgh have discovered that red squirrels in Britain and Ireland carry the two bacterial species that cause leprosy in humans. Once rampant in medieval Europe, leprosy dramatically declined by the end of the Middle Ages for reasons that are still unclear. About a century ago, leprosy in Europe […]

Contact Lenses Alter Eye Bacteria, Making It More Skin-Like

Contact lenses may alter the natural microbial community of the eyes, according to a study published this week in mBio®, an online open-access journal of the American Society for Microbiology. In a study of 58 adults seeking outpatient eye care, researchers at New York University School of Medicine found that contact lenses make the eye […]

Skin Bacteria Could Protect Against Disease

There are more and more examples of the ways in which we can benefit from our bacteria. According to researcher Rolf Lood from Lund University in Sweden, this is true for the skin as well. He has shown that the most common bacteria on human skin secrete a protein which protects us from the reactive […]

Gut Bacteria Could Help Prevent Cancer

Researchers have shown that various types of intestinal bacteria might be factors in both causing and preventing obesity, and in other conditions and diseases. Now, a UCLA study suggests that it could also potentially be used to reduce the risk for some types of cancer. The research, published online April 13 in the peer-reviewed journal PLOS ONE, […]

Bacteria In Smokeless Tobacco Products May Be A Health Concern

Several species of bacteria found in smokeless tobacco products have been associated with opportunistic infections, according to a paper published August 26 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. Bacillus licheniformis and Bacillus pumilus could potentially cause inflammation of the lungs, as well as opportunistic infections, said coauthor Steven Foley, PhD, research microbiologist, […]

The Current State Of Psychobiotics

the-current-state-of-psychobiotics-1024w

Now that we know that gut bacteria can speak to the brain — in ways that affect our mood, our appetite, and even our circadian rhythms — the next challenge for scientists is to control this communication. The science of psychobiotics, reviewed October 25 in Trends in Neurosciences, explores emerging strategies for planting brain-altering bacteria […]

Fungus In Humans For First Time As Key Factor In Crohn’s Disease

A fungus has been identified as a key factor in the development of Crohn’s disease, an international team of researchers has identified for the first time. A Case Western Reserve University School of Medicine-led team of international researchers has for the first time identified a fungus as a key factor in the development of Crohn’s […]

Vinegar Could Potentially Help Treat Ulcerative Colitis

Vinegar is the perfect ingredient for making tangy sauces and dressings. Now, researchers report in ACS’ Journal of Agricultural and Food Chemistry that the popular liquid could also help fight ulcerative colitis, an inflammatory bowel disease that research suggests is related to the gut microbiome. They found that vinegar suppressed inflammation-inducing proteins while improving the gut’s […]
