Heart disease and fatty clogs in the arteries go hand in hand. But new evidence suggests the fatty molecules might come not only from what you eat, but from the bacteria in your mouth, scientists report. The research may explain why gum disease is associated with heart trouble.

Nitric oxide gas produced by a type of harmful bacteria lets roundworms know to stay away from it, says a new study.

We’ve found bacteria that turn carbon dioxide into hydrocarbons useful for fuel and plastic, and now we’ve mimicked their enzymes to do it even better

Antimicrobial fabric could slow the spread of diseases like Ebola. These nanofibres kill viruses and bacteria, and their active ingredient recharges in daylight

Scientists have found that deleting a single gene in a particular strain of gut bacteria causes changes in metabolism and reduced weight gain in mice.

Antimicrobial resistant pathogens crowdsource friendly bacteria to survive in immune cells and cause disease, a new study has revealed.

Higher daily doses of rifampin, a cornerstone of tuberculosis treatment, killed more TB bacteria in sputum cultures, and the higher doses did so without increasing the adverse effects of treatment, according to a randomized controlled trial.

Dietary fiber increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness, according to a preclinical study published May 15 in the journal Immunity. A high-fiber diet blunts harmful, excessive immune responses in the lungs while boosting antiviral immunity by activating T cells. These dual benefits were mediated by changes in the composition of gut bacteria.
