Researchers around the world are on a quest to create artificial blood. This blood would be universal and capable of lasting years, allowing it to be used in medical emergencies or remote locations. However, formulating an alternative to the liquid of life is no easy feat.
Scientists want to "create the lab-grown burger of blood," or a blood substitute, that "bleeds, or at least operates in the body, almost exactly like the real thing," said The New Yorker. However, creating fake blood is notoriously difficult, as scientists "don't yet understand everything that blood does or how it does it." Despite this, they are making headway.
In Japan, clinical trials are underway to "assess artificial blood, usable for all blood types and storable for up to two years, as a potential solution to critical shortages in blood supplies for emergency and chronic health care worldwide," said Newsweek. The artificial blood "contains hemoglobin molecules from expired donor blood, which are encapsulated in protective lipid shells to create artificial red blood cells," said NewsNation. "The new mixture is capable of carrying oxygen throughout the body."
In Maryland, scientists have created similar artificial blood that can be freeze-dried to last for years. (Real blood only lasts about 42 days.) It's designed so that "at the moment it's needed, a medic can mix it with water and, within a minute you have blood," Allan Doctor, a scientist at the University of Maryland, told NPR.
Use of artificial blood in rabbits has already proven promising. And researchers are hopeful for human trials. |
