In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the ...

A bacterial defense system called SPARDA employs kamikaze-like tactics to protect cells and could be useful in future ...

Lucy Shapiro received this year’s Lasker Special Achievement Award for her discovery of how bacteria use genetic circuits to encode three-dimensional cellular life. “I was quite shocked, truly,” said ...

The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. Among these molecules are lectins—proteins that ...
