Cockroach Caca Contains Chemical Messages Made by Microbes

Microbes play a huge role in our nutrition, our immunity, maybe even our mental health. But we aren’t the only ones that rely on these armies of resident bacteria. "Baby cockroaches, the ones that just emerge from the egg, don't have any gut bacteria." Coby Schal, an entomologist and chemical ec... Read More

Cyclic-di-GMP takes center stage

How does a single-celled organism ‘know’ how to respond to its environmental conditions? Understanding microbial cell signaling is one way to determine how bacteria will react in a particular setting. In the past decade, researchers have revealed a significant role for cyclic-di-GMP in bacterial... Read More
