Key Points:
🧪 What is Quorum Sensing? Bacteria use signaling molecules called autoinducers to sense their population density and trigger collective behaviors, such as forming biofilms or producing toxins.

💡 Bioluminescence and Beyond: Vibrio fischeri bacteria light up to help squids evade predators, showcasing the symbiosis enabled by quorum sensing.

🛡️ Biofilm Formation: Dense bacterial communities use quorum sensing to form protective barriers, enhancing survival against antibiotics and environmental stress.

⚙️ Molecular Mechanisms: Autoinducers act like "text messages," activating genes once a critical threshold is reached, enabling a synchronized bacterial response.

🚑 Medical Applications: Quorum sensing inhibitors offer new strategies to disrupt harmful bacterial communication and combat antibiotic resistance.

📈 Future Research: Advances in synthetic biology harness quorum sensing to program bacteria for targeted therapies and environmental cleanup.
