A Group of researchers at University of California, San Diego found that Single-cell bacteria could communicate with other members by sending out electronic signals.

Bacteria lives in biofilms, which they create on solid surface by secreting a large, slimy framework. You can find this biofilms everywhere. It could be on shower heads or on your teeth, could be on boat hulls and on rocks.

Researcher at UCSD, Jintao Liu, noticed something wired when she studied about the biofilms two years ago. According to her biofilms would expand and stop at every two hour of regular intervals.



This study is totally different from the one that many scientists known for years. According to them bacteria can coordinate by exchanging specific chemicals. This process of chemical commutation known as Quorum sensing.

Furthermore, scientists discovered that they possess small pores i.e. ion channels in their membranes. It can be open and shut like microscopic portholes, allowing the cells to send and receive positively charged potassium ions.
