Innovations in AI and sensing technologies are revolutionizing environmental and biological surveillance. Researchers developed a self-powered microfluidic sensor detecting toxic amines in water via electrochemiluminescence driven by fluid flow. Concurrently, AI approaches assess stress levels in Amazonian farmed fish, enhancing animal welfare, while novel hyperspectral imaging techniques enable precise quantification of ship emissions. These advances offer scalable, sensitive, and eco-friendly monitoring tools critical for sustainability and health.
