Friday, November 24, 2023 – 12:33 AM Researchers at the University of Texas and the University of Delaware have discovered a potential memory system that allows Escherichia coli bacteria to remember experiences, and that a single-celled organism that does not have a brain or nervous system can form memories and pass those memories to… For generations to come, as far as they know, this type of bacterial memory has never been discovered before, according to Science Alert. The ability of bacteria to store memories The ubiquitous E. coli bacterium is one of the most well-studied forms of life on Earth, and with Scientists are still discovering unexpected ways for it to survive and spread, and it is clear that the memory that scientists are discussing in this case is not the same as conscious human memory. Rather, the phenomenon of bacterial memory describes how information from past experiences affects current decision-making. According to experts, bacteria do not have brains, but they can collect information from their environment, and if they encounter that environment repeatedly, they can store that information and access it quickly later for their benefit. He also conducted the experiments, which is a test to see whether E. coli cells on one plate will aggregate Together to form a single migratory mass that moves with the same engine. This behavior generally indicates that cells are swarming efficiently for a suitable environment. The molecular mechanism behind the memory system The team found that intracellular iron was the strongest predictor of whether bacteria moved or stayed, and low levels of iron were associated with faster and more efficient swarming, while Higher levels lead to a more sedentary lifestyle. Moreover, this ferrous memory was transmitted to at least 4 successive generations of daughter cells, which are formed from the division of the parent cell into two new cells. The study authors have not yet determined the molecular mechanism behind this potential memory system or its heritability. However, the strong association between intracellular iron and swarming behavior between generations suggests that there is a level of ongoing adaptation at play. While genetics are known to play a role in passing on remembered biological settings across generations of E. coli by regulating the on and off settings of E. Certain.
