Blood can typically be stored for only six weeks after donation, but a potential solution attempts to dry blood by using a sugar-based preservative. New work in ultrasound technology looks to provide a path to inserting these sugars into human red blood cells, allowing the molecule trehalose to enter the cells and prevent their degradation when dried for preservation.
