Scientists at the Beijing Institute of Technology have developed the world’s lightest brain-controlling device for insects, weighing just 74 milligrams—lighter than the nectar load a bee typically carries. This device is attached to a bee’s back, with three needles penetrating its brain to deliver electronic pulses that direct its flight with 90% accuracy. The innovation marks a significant improvement over previous insect controllers, which were heavier and caused quicker fatigue. The researchers envision using these mind-controlled bees for military reconnaissance and disaster relief operations, such as searching for survivors after earthquakes. The system mimics the parasitic control seen in cordyceps fungi, using ultra-thin polymer films embedded with tiny computer chips to interface with insect brains. While promising, challenges remain, including the need for wired power and limited endurance due to battery weight and insect fatigue. Despite these hurdles, the technology offers enhanced stealth and mobility compared to synthetic drones, making it valuable for covert surveillance and emergency response. However, the development also raises ethical
