If you have ever had to clean the drain in your sink or the film of dirt off of the shower wall, chances are that a bacteria colony did reside there at one time. You know what I am talking about...That build up of film on your shower door/wall which progressively gets more opaque and changes color if left untouched by a sponge with cleaner. Bacteria colonies arise all over the place. How do bacteria colonies grow? How do individual bacteria in colonies communicate with each other? Scientists have made progress into unveiling the details below.
In the video shown below -- which is 10 seconds in length, the growth of bacteria is shown along with the immediate conversations between them in a community setting:
Scientists have often wondered how bacteria communicate when in a colony setting. This step represents an advance in the detection of communication. A step in the right direction to say the least. Exciting as the results may be, the researchers now have their hands full in pushing the project further.
