 Sciences delivered a new study that can significantly increase the chances of people surviving serious injury especially when they need a blood transfusion.  They have found a way to provide or create a universal blood supply of "universal red blood cells". 

An international team of academic and industry scientists has come up with a feasible way of making universal red blood cells that are stripped of their blood type. The hope is that it can be developed into a viable way of relieving blood bank shortages.

People often times have to be typed for their blood before they can receive a blood transfusion.  That can take time if a person has sustained a serious injury and mistakes are made from time to time.  This could help blood banks keep up with demand as harder to bank blood types could be covered with a universal variety.
