Portable, injectable clotting agent could treat trauma victims on the front lines

In a hospital, internal bleeding can be controlled with the transfusion of clotting agents, such as platelets, but they require careful storage and refrigeration and can't be carried by first responders. Now, researchers report an injectable clotting agent that reduced blood loss by 97 percent in mice models. The freeze-dried agent, which has a physical consistency of cotton candy, can be stored at room temperature for several months and reconstituted in saline before injection.
