  • The Best Offense Against Bacteria is a Good Defense
    A small protein active in the human immune response can disable bacterial toxins by exploiting a property that makes the toxins effective – but also turns out to be a weakness. These toxins, which are released by bacteria, have malleable surfaces that allow them to ...More

  • Researchers Learn How Bacteria Control Their Size
    Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube. Using this method, scientists ...More

  • Researchers Shed Light on How Microbial 'Dark Matter' Might Cause Disease
    One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still a puzzle to scientists. It is estimated by scientists that roughly half of bacteria living in human ...More

  • 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
