It appears that some superbugs have evolved to develop the ability to manipulate the immune system to everyone's advantage. A team of researchers at The University of Western Ontario, led by Joaquin (Quim) Madrenas of the Robarts Research Institute, has discovered some processes that reduce the ... Read More
Researchers at the Institute of Food Research (IFR) in Norwich, UK., have shown for the first time that salmonella relies on glucose for its survival; raising the possibility of vaccine protection against this food-borne illness and other disease-causing bacteria, including super bugs.

Agricultural Research Service (ARS) scientists have used antibody-coated immunomagnetic beads (IMBs) to detect Yersinia pestis, the bacterium that causes bubonic plague.
While similar techniques are often used to detect various bacterial species, the methods must be altered to suit specific p... Read More
Yes, going gluten free is trendy. And foregoing products made from wheat like bread, cookies, cakes and other processed foods is necessary for people with celiac, an auto-immune problem caused by gluten, a protein in wheat. But when there’s trendy, there’s always folks ready to trash the trend n... Read More
