An anonymous reader shares a report: Scientists have been working on creating synthetic blood for years now.
The hope is that this substance will have a longer shelf life than human blood -- which can only be refrigerated for 42 days -- and eventually can be packaged and stored for use in emergencies.
If this works, thousands of lives could be saved every year.
"People can't show up fast enough and then the system can't draw their blood fast enough to meet the need," said Allan Doctor, a physician and researcher at the Washington University in St. Louis.
Doctor's lab has been working to create a blood substitute called ErythroMer, comprised of human hemoglobin, sourced from the red blood cells in expired blood at blood banks, and a synthetic polymer.
This synthetic blood is actually a dehydrated powder, which would allow it to be stored for years, rather than weeks, and easily transported.
