Astrocytes: The New Frontier in Memory Storage and Learning

A new study by NYU scientists, published in Nature Communications, reveals that kidney cells can learn and form memories, similar to brain neurons. This discovery offers a potential literal interpretation of the biblical phrase "bochen klayos" (examine the kidneys) from Yirmiyahu 17:10, traditionally seen as metaphorical. The research suggests that the pasuk's reference to testing the kidneys alongside the heart may reflect a profound biological reality, indicating a comprehensive examination of both conscious thought and unconscious cellular memory.
