  • Humans and Chimps Share Genetic Strategy in Battle Against Pathogens
    A genome-wide analysis searching for evidence of long-lived balancing selection—where the evolutionary process acts not to select the single best adaptation but to maintain genetic variation in a population—has uncovered at least six regions of the genome where humans and ...More

  • Why Bad Immunity Genes Survive
    This electron microscope image shows yellow particles of a mouse leukemia virus named Friend virus emerging or "budding" out of an infected white blood cell known as a T-cell. By allowing the Friend virus to mutate and evolve in mice, University of Utah researchers produced ...More

  • Genetics Study Reveals How Bacteria Behind Serious Childhood Disease Evolve to Evade Vaccines
    Genetics has provided surprising insights into why vaccines used in both the UK and U.S. to combat serious childhood infections can eventually fail. The study, published today in Nature Genetics, which investigates how bacteria change their disguise to evade the vaccines, ...More

  • Researchers Reveal New Evidence of Genetic 'Arms Race' Against Malaria
    For tens of thousands of years, the genomes of malaria parasites and humans have been at war with one another. Now, University of Pennsylvania geneticists, in collaboration with an international team of scientists, have developed a new picture of one way that the human ...More

  • Scientists Find Method to Probe Genes of the Most Common Bacterial STI
    In a new study from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, scientists describe successfully mutating specific genes of Chlamydia bacteria, which cause the most common sexually transmitted infection in ...More

  • Discovery of Two New Genes Provides Hope for Curbing Staph Infections
    The discovery of two genes that encode copper- and sulfur-binding repressors in the hospital pathogen Staphylococcus aureus means two new potential avenues for controlling the increasingly drug-resistant bacterium, scientists say in the April 15, 2011 issue of the Journal ...More

  • Host Genetics Plays Unexpected Role in Dance with Pathogen
    A new study suggests that differences in the host's genetics can make a big difference in susceptibility bacterial infection. In a study in the February 2011 Infection and Immunity, Virginia L. Miller of the University of North Carolina, Chapel Hill, and her collaborators ...More

  • Gonorrhea Acquires a Piece of Human DNA
    If a human cell and a bacterial cell met at a speed-dating event, they would never be expected to exchange phone numbers, much less genetic material. In more scientific terms, a direct transfer of DNA has never been recorded from humans to bacteria. Until now. Northwestern ...More

  • Gene 'Relocation' is Key to Most Evolutionary Change in Bacteria
    In a new study, scientists at the University of Maryland and the Institut Pasteur show that bacteria evolve new abilities, such as antibiotic resistance, predominantly by acquiring genes from other bacteria. The researchers new insights into the evolution of bacteria partly ...More

  • Gut Microbes Regulate Genes That Control Obesity and Inflammation
    If you are looking to lose weight in the coming year, you may need help from an unexpected place: the bacteria in your gut. That's because scientists have discovered that the bacteria living in your intestines may play a far more significant role in weight loss and ...More
