  • Researchers Study Switches That Control When Bacteria Turn Deadly
    No matter how many times it's demonstrated, it's still hard to envision bacteria as social, communicating creatures. But by using a signaling system called "quorum sensing," these single-celled organisms radically alter their behavior to suit their population. In short, ...More

  • Recruiting Bacteria to be Technology Innovation Partners
    For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of "bad" biofilms around – they even cause pesky dental plaque and a host of other more serious medical problems – a team at the Wyss Institute ...More

  • Scientists Study Motion Patterns of Bacteria in Real Time
    A team of researchers at Boston University and Stanford University School of Medicine has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony. The researchers ...More

  • New Insights in Survival Strategies of Bacteria
    Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial community that is surrounded by a protective slime ...More

  • How Bacteria Battle Fluoride
    Researchers have determined key structural differences that allow a subset of CLC transporters to preferentially select fluoride over chloride, which can help bacteria expel toxic fluoride. The binding site of a standard CLC transporter is shown here. He’s not a ...More

  • Bacteria Harbor Secret Weapons Against Antibiotics
    The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide. And scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to ...More

  • Targeting the Protein-Making Machinery to Stop Harmful Bacteria
    One challenge in killing off harmful bacteria is that many of them develop a resistance to antibiotics. Researchers at the University of Rochester are targeting the formation of the protein-making machinery in those cells as a possible alternate way to stop the bacteria. ...More

  • Smelly Clothes? Blame it on the Bacteria
    Polyester clothes smell worse than cotton, following intensive exercise by their wearers, because bacteria that cause odor grow better on polyester, according to research published ahead of print in the journal Applied and Environmental Microbiology. In the study, the ...More

  • Discovery Reveals How Bacteria Distinguish Harmful Versus Helpful Viruses
    When they are not busy attacking us, germs go after each other. But when viruses invade bacteria, it doesn’t always spell disaster for the infected microbes: Sometimes viruses actually carry helpful genes that a bacterium can harness to, say, expand its diet or better ...More

  • Harnessing the Power of Bacteria's Sophisticated Immune System
    Bacteria’s ability to destroy viruses has long puzzled scientists, but researchers at the Johns Hopkins Bloomberg School of Public Health say they now have a clear picture of the bacterial immune system and say its unique shape is likely why bacteria can so quickly ...More
