美国得克萨斯大学奥斯汀分校的科学家们最近发现，一些细菌，包括大肠杆菌，能够利用铁含量的多少来存储不同的行为信息。这些信息可以在对某些刺激的反应中被激活，并且可以被代代相传。研究显示，这些由铁产生的“记忆”至少持续了四代，到第七代就消失了。
科学家们指出，这种记忆能力可能是这些细菌在进化过程中获得的一种优势。他们表示，这种记忆能力可以帮助细菌在环境中生存和繁殖，并且可以被传递给后代。
这些发现对于人类来说也具有重要的意义。研究人员可以通过研究这些细菌的记忆能力，来更好地了解人类记忆的机制。同时，这些发现还可以为人类创造新的技术和方法，以储存和传递信息。

Title: Bacteria can store memories and pass them down
Keywords: bacteria, storing memories, passing down
News content:
Scientists at the University of Texas at Austin recently discovered that some bacteria, including E. coli, can store different behaviors using the amount of iron they contain. This information can be activated in response to certain stimuli, and it can be passed down from generation to generation. The study showed that these memories made by iron can last at least four generations and disappear by the seventh generation.
The scientists pointed out that this memory ability may have been an advantage for these bacteria in evolutionary processes. They said that this memory ability can help the bacteria to survive and reproduce in different environments.
These findings are of great significance to humans. Researchers can study the mechanisms of human memory by learning from these bacteria. At the same time, these findings can also create new technologies and methods for storing and transmitting information.
