Communication is universal but the means and methods are not. You know how humans talk. You might understand what animals are trying to express with their expression and sounds but how do bacteria talk? In this video from a TED Talk / TED-Ed session, Bonnie Bassler, molecular biologist from the Princeton University, explains how bacteria and similar organisms communicate and coordinate their activities. Very interesting and very informative. Enjoy!
