Summary:

• **A New Medical Discovery**: Scientists have created a special spray-on powder that can quickly stop serious bleeding from wounds. When sprayed on a cut or injury, this powder helps the blood clot and seal the wound much faster than traditional bandages, which could save lives in emergencies.

• **How It Works**: The powder is made from special materials that stick to the wound and help your body's natural healing process work better and quicker. This invention is particularly helpful for people who are badly injured and need immediate help before they can get to a hospital.
