Montana State University researchers have identified a biological pathway that allows cells to produce the essential amino acid cysteine when primary systems fail, a process previously deemed impossible by the scientific community. Published May 21 in Nature Chemical Biology, the discovery reveals how mammalian cells utilize a backup mechanism to cleave carbon-sulfur bonds in cystine, … Read more
Researchers at the University of São Paulo (USP) have identified 45 previously unknown toxins produced by Salmonella bacteria, a discovery that could influence future antibiotic development and biotechnology. The team, based at the Center for Research in Bacterial and Bacteriophage Biology (B3 RIDC), analyzed 6,165 Salmonella samples to map these microscopic “spear-like” defense systems. The … Read more
The Hidden Trigger: How Gut Bacteria Drive Colon Cancer For years, the medical community has tracked a troubling link between the common gut bacterium Bacteroides fragilis and the formation of colon tumors. We knew this bacterium secreted a toxin—known as BFT—that damaged the colon’s lining, potentially paving the way for colorectal cancer. However, the “how” … Read more
Gum Disease Breakthrough: Silencing the ‘Bad Influencer’ in Your Mouth For decades, the fight against gum disease has relied on aggressive tactics – scraping, cutting, and broad-spectrum antibiotics.
