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. But formulating an alternative to the crucial 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. Yet creating fake blood is notoriously difficult as the experts "don't yet understand everything that blood does, or how it does it". Despite this, they have begun to make 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 supplies for emergency and chronic health care worldwide", said Newsweek. In Maryland, US scientists have concocted similar artificial blood that can be freeze-dried to last for years.
Currently, "approximately 118.5 million blood donations are collected worldwide, with 40% gathered in high-income countries, which comprise only 16% of the global population", said Al Jazeera. Experts estimate that "2,000 units of blood per 100,000 people are needed to meet global medical demands", but "severe shortages persist, especially in sub-Saharan Africa, South Asia and Oceania".
Artificial blood could fill a crucial gap. "But because this field has been so challenging, the proof will be in the clinical trials," Tim Estep, a scientist at Chart Biotech Consulting who consults with companies developing artificial blood, told NPR. |
