Bacteria Memory Discovered, Passed on for Generations
🔬 Explore the groundbreaking discovery of a memory system in Escherichia coli! Scientists from the Universities of Texas and Delaware have revealed an extraordinary bacterial memory that lasts for hours and spans multiple generations. Unlike human conscious memory, this system impacts the microorganisms' decision-making based on environmental cues. Lead researcher Souvik Bhattacharyya delves into how bacteria, devoid of brains, can store information from their surroundings, influencing their behavior when exposed to familiar environments.
🌐 Join us on a journey through over 10,000 bacterial 'swarming' assays, where Escherichia coli cells showcased collective movement or formed biofilms based on environmental conditions. Discover the pivotal role of intracellular iron in shaping bacterial behavior, with low levels triggering faster swarming and higher levels leading to a more settled lifestyle. The iron memory persists through at least four generations, showcasing a unique intergenerational conditioning effect.
🧬 Uncover the mysteries of this memory system's molecular mechanism and its potential applications in bacterial adaptation to challenging conditions or antibiotics. The study, published in PNAS, sheds light on a previously unknown facet of bacterial behavior.
🔍 Stay tuned for a fascinating exploration into the hidden world of bacterial adaptation and memory!
