If you’ve ever given blood, you’re probably now on the email distribution list for the organization you donated through and get frequent requests to come in and give again. That’s because a pint of blood expires after about six weeks in a refrigerator and so far there’s no alternative to donated human blood for treating a very sick person in need of a transfusion. If only freeze-drying were possible. Then blood could be stored at room temperature for much longer – just think how that could be helpful for war zones and even astronauts in space.
