This spray-on powder can stop life-threatening bleeding in 1 second

Researchers at South Korea's KAIST have developed a spray-on powder that can stop life-threatening bleeding in about one second. The powder instantly forms a strong gel over a wound, making it particularly effective for deep and irregular injuries where conventional hemostatic products often fail. The spray remains effective even after years of storage in harsh conditions, addressing a major limitation of existing emergency products. Originally designed for battlefield medicine, the technology could transform emergency response in hospitals, ambulances, and disaster scenarios—turning what's typically a race against time into something you can actually win.
