    "body_text": "University of Illinois Chicago researchers developed FINICI to solve a blind spot in fluorescent biosensors that go dark when they detect activity. The method reverses that optical readout without requiring scientists to redesign the sensor from scratch. Tests mapped bursts of Src kinase at the cell membrane, cGMP clusters, and Syk activity near immune-cell scaffolding. The technique may help researchers see why a drug signal works in one cellular neighborhood and fails in another, but it remains a research imaging method.",
