  • Mothers Can Pass Traits to Offspring Through Bacteria's DNA
    It's a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents' DNA. But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown ...More

  • Scientists Take First X-ray Portraits of Living Bacteria at the LCLS
    Researchers working at the Department of Energy’s SLAC National Accelerator Laboratory have captured the first X-ray portraits of living bacteria. This milestone, reported in the Feb. 11 issue of Nature Communications, is a first step toward possible X-ray ...More

  • Researchers Discover How Bacteria Coordinate the Timing and Location of Subcellular Processes
    Not unlike an urban restaurant, the success of a bacterial cell depends on three things: localization, localization and localization. But the complete set of controls by which bacteria control the movement of proteins and other essential biological materials globally within ...More

  • Scientists Study Bacterial Adaptive Defenses
    Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity. Two experiments undertaken at the Department of Energy's SLAC National Accelerator Laboratory provide new insight at the heart of ...More

  • New Bacterial Language is Discovered
    Bacteria communicate by means of chemical signals and can develop common characteristics through this "agreement" and also develop their potential pathogenic effects in this way. Scientists working with Dr. Helge B. Bode, an Merck-endowed professor for molecular ...More

  • Iron Overload Disease Causes Rapid Growth of Potentially Deadly Bacteria, UCLA Study Finds
    Every summer, the news reports on a bacterium called Vibrio vulnificus found in warm saltwater that causes people to get sick, or die, after they eat raw tainted shellfish or when an open wound comes in contact with seawater. People with a weakened immune system, chronic ...More

  • 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
