One of the bacteria brainThey have no mouths with which to speak, nor do they have senses like ours. Although it may seem that it is not easy to create memories in such a situation, it has been shown that bacteria can not only create memories, but also pass on these memories to the next generations.

With its scientific name Escherichia coliknown as Plot printed The type of bacteria mentioned is one of the most common bacteria in the world and has been the subject of many different studies. Yet this single-celled creature continues to surprise scientists endlessly.

E. coli can remember its experiences for hours.

Of course, it doesn’t show that E. coli actually creates memories through tests like matching the cards. In other words, they don’t have conscious memory like we do. They mainly show these characteristics in the changes in decision-making mechanisms. from the University of Texas Souvik Bhattacharyya, the lead author of the researchers’ study, said that bacteria store information about the environment they are in, and they can use these memories if they are in an environment very often.

In the experiment involving more than 10,000 bacteria, the spreading and grouping behavior of the bacteria was observed. While searching for food, bacteria move quickly from one point to another. Bacteria spread out and search for food in the area, and when they find food, they gather together. cellular iron While bacteria move quickly in environments with low iron density, they congregate in environments with low iron density. When moved to an environment where iron is low, they quickly move to the iron-rich environment and again. They don’t look for food.

They can also pass on information to subsequent generations.

What is also striking about the research is that the bacterium has obtained this information. passing it on to the next generations happened. Although this knowledge was revealed to have been passed on for at least four generations, subsequent generations were observed to evolve even faster.

Scientists believe that bacteria create a memory system based on iron. There was no oxygen in the atmosphere for a very long time before our planet became what it is today bacteria to fulfill its intracellular functions iron used. Therefore, it is considered normal to shape memory creation mechanisms with the help of iron.

Researchers study the movement and movement of bacteria memory mechanisms He believes that better understanding will have a major impact on future studies. Thus, it will be possible to reveal how bacteria develop mechanisms and become immune to drugs.
