Watch DNA Damage & Repair in Real-Time: New Sensor Breakthrough

What if we could watch our cells heal themselves in real-time after being damaged? Scientists have created a revolutionary fluorescent sensor to observe DNA damage and repair as it happens. Unlike older methods that produced only static snapshots by killing cells, this new tool creates a continuous movie of the entire repair process inside living organisms. The sensor is built from a natural protein, so it gently highlights damage without interfering with the cell's own repair machinery, a key advantage over disruptive antibodies. This breakthrough fundamentally changes how we study the processes behind aging, cancer, and other diseases. Practical applications include making early cancer drug testing cheaper, faster, and more accurate and precisely measuring exposure to radiation.
