Huazhong Agricultural University scientists have built a new system using neural networks that can act as an early warning system for solar flares. These flares are difficult to predict and can be dangerous, disrupting radio communications, satellites, and power grids.
Scientists from the Beijing Institute of Technology have injected a rat with liquid metal designed to work as an electrode. This electrode can link the brain or spinal cord to the rest of the body and is usually made of solid metal; this is the first time scientists are trying with liquid metal. The results were promising and the researchers hope that it can be used as an artificial nerve and help treat neural diseases.
AI is becoming more prevalent in today’s society. By collecting data on facial expressions, heart rate, etc., AI can sense and react to human emotions.
