A new study in the journal Microbiology Spectrum highlights the potential of using a natural compound from maple to combat the bacteria responsible for tooth decay: Streptococcus mutans.

The compound, epicatechin gallate, is a powerful and safe alternative to traditional plaque-fighting agents. Its natural abundance, affordability and lack of toxicity make it especially promising for inclusion in oral care products such as mouthwashes, offering a safer option for young children, who often accidentally swallow mouthwash.

The new study emerged as an offshoot of research into natural compounds that inhibit biofilm formation in Listeria monocytogenes, a foodborne pathogen.

As is often the case in science, the researchers made an unexpected observation tha...

In a first study of its kind, scientists characterized different bacterial populations isolated over time from potable (drinking) water from the International Space Station (ISS).

By all appearances, the universe beyond Earth is a vast, lonely, and sterile space. Yet, wherever humans may travel, an abundance of microbial life will follow.

In a first study of its kind, lead author Jiseon Yang at th...

A visit to the dentist typically involves time-consuming and sometimes unpleasant scraping with mechanical tools to remove plaque from teeth. What if, instead, a dentist could deploy a small army of tiny robots to precisely and non-invasively remove that buildup?

A team of engineers, dentists, and biologists from the University of Pennsylvania developed a microscopic robotic cleaning crew...

Many infectious pathogens are difficult to treat because they develop into biofilms, layers of metabolically active but slowly growing bacteria embedded in a protective layer of slime, which are inherently more resistant to antibiotics. Now, researchers at Caltech and University of Oxford have made progress in the fight against biofilms. Led by Dianne Newman, the Gordon M. Binder/Amgen Professor of Biology and Geobiology, the group identified a protein that degrades and inhibits biofilms of Pseudomonas aeruginosa, the primary pathogen in cystic fibrosis (CF) infections.

“Pseudomonas aeruginosa causes chronic infections that ar...
