Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

As much as rainforests or deep-sea vents, the human gut holds rich stores of microbial chemicals that should be mined for their pharmacological potential.

Life scientists are increasingly adopting the belief that microorganisms are virtually everywhere and are responsible for just about everything. This, plus the maturation of molecular- level methods of working with these tiny creatures, is a source of considerable optimism for microbiologists as the 93rd general meeting of the American Society for Microbiology (ASM) convenes in Atlanta this week. What they see, in career terms, is that progress in their field is bound to yield an ever-widening

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

The animal world is full of clever solutions to bioengineering challenges.
