Where bacteria get their genesBacteria acquired up to 90 % of their genetic material from distantly related bacterial species, according to new research from the University of Arizona in Tucson. The finding has important biomedical implications because such gene-swapping, or lateral gene transfer is the way many pathogenic bacteria pick up antibiotic resistance or become more virulent.

The research also solves a long-standing evolutionary puzzle. Many scholars have argued that the creation of traditional family trees does not make sense for bacteria, because their genomes represent a mixture of genetic material from their parental cells and other types of bacteria.An international meeting by researchers from 19 countries has reached agreement for the first time the uniform standards for antioxidant. The decision may eventually produced view more reliable information on consumers, which misleading claims concerning which level and effect of disease-fighting links in its food, healthcare and beauty products represent, say the researchers.
