Belly bacteria are talking. Your body listening?
CALTECH (US)—We are not alone—even in our own bodies. The human gut is home to 100 trillion bacteria, which, for millions of years, have co-evolved along with our digestive and immune systems. Some can be harmful, some beneficial, and—according to new research—other microbes may be perched somewhere in between. (more…)

Wonder drug’s sticky secret weapon
“If we are to have any hope of outpacing the antibiotic resistance obtained by bacteria, it is paramount that we fully understand the mechanism of action of the antibiotics we currently use,” says Johna van Stelten. “Unfortunately, this is often very difficult as evidenced by the fact that, 50 years on, we are still learning new things about them.”

Detector spots respiratory infections much earlier
Vanderbilt University researchers David Wright (right) and Frederick Haselton (left) have developed a new detection method that can catch respiratory infections at a very early stage. The system “could easily be packaged in a disposable device about the size of a ballpoint pen,” says Haselton. (Credit Steve Green/Vanderbilt university)
