|Bacteria build communities using chemical signals comparable to radio waves|
by Wayne Lewis, University of California, Los Angeles
The thought of bacteria joining together to form a socially organized community capable of cooperation, competition and sophisticated communication might at first seem like the stuff of science fiction—or just plain gross.
But biofilm communities have important implications for human health, from causing illness to aiding digestion. And they play a role in a range of emerging technologies meant to protect the environment and generate clean energy.
New UCLA-led research could give scientists insights that will help them cultivate useful microbes or clear dangerous ones from surfaces where biofilms have formed—including on tissues and organs in the human body. The study, published in the Proceedings of the National Academies of Science, describes how, when biofilms form, bacteria communicate with their descendants using a chemical signal analogous to radio transmissions.
