"Two types of bacteria found in the soil have enabled scientists to get the dirt on how resistance to antibiotics develops along with a separate survival strategy.The study identifies an atypical antibiotic molecule and the way in which the resistance to that molecule arises, including the ident...

This episode: Scientists engineered E. coli to seek and destroy pathogens!
(10 MB, 11 minutes)
A bacterium can sense pathogens in the body, swim toward them, and release a deadly biofilm-busting payload. This process is called pseudotaxis, and could be modified for many... Read More

Why are obesity, juvenile diabetes and asthma increasing? Is it something in the environment or in our modern lifestyle? Dr. Martin Blaser thinks that it may be due to changes in our microbiome – the ecosystem of tiny microscopic creatures that live in and on us. Learn about his hypothesis th... Read More
Previous research has shown that the overuse of antibiotics has a hand in promoting an antibiotic-resistant strain of bacteria and now a new study published in the journal mBio has found that an antibiotic common to soaps and hand sanitizers actually promotes the growth of Staphylococcus aureus ...
