Researchers have found evolved pertussis, as whooping cough is scientifically known, in Finland, France, Italy, Japan and the U.S. As we previously reported, the evolved bacteria don't seem to be more dangerous than their predecessors. Nevertheless, the U.S. Centers for Disease Control and Preve... Read More
Colorectal cancer patients have fewer beneficial gut bacteria and more harmful microbes than those without the disease, researchers from the New York University School of Medicine report in Friday’s edition of the Journal of the National Cancer Institute.
While previous research had suggested... Read More

Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More

Norwegian researchers in Trondheim have achieved surprising results by exploiting nature's own ability to clean up after oil spills.
We all know that marine bacteria can assist in cleaning up after oil spills. What is surprising is that given the right kind of encouragement, they can be even mo... Read More
Antibiotic-resistant bacteria are on the rise, making it more and more difficult to treat infections. But research suggests that the best defense against harmful bugs could be a healthy population of “good” gut bacteria. The human relationship with microbial life is complicated. At almost any su...
