Spray-On Powder That Seals Life-Threatening Wounds

Pretty cool, a powder that stops bleeding:

KAIST scientists have created a fast-acting, stable powder hemostat that stops bleeding in one second and could significantly improve survival in combat and emergency medicine.

Severe blood loss remains the primary cause of death from combat injuries. To address this challenge, a research team at KAIST that included an active duty Army Major set out to develop a faster and more reliable way to stop bleeding.

Their work led to a next-generation powder-type hemostatic agent that can halt bleeding within one second when sprayed directly onto a wound, offering a potential breakthrough for saving lives on the battlefield.
