00:00It looks like we have finally made artificial universal blood.
00:05Here's what's happening. You might know that you have a blood type.
00:07The letter means whether or not you have A or B sugars in your blood, or both or none.
00:12And then the plus or minus means whether or not you also have another kind of protein.
00:15And you can't just give anyone any blood. It has to be compatible.
00:18So now, scientists are testing a new artificial blood that could be used on anyone.
00:23It's made by taking expired donor blood, which expires after only 42 days,
00:27and then extracting the protein that helps red blood cells move oxygen.
00:30And then they wrap that protein in a protective shell to make artificial blood cells,
00:34with none of the blood type markers.
00:36And then on top of that, it could be stored for up to two years at room temperature.
00:39They've already done a successful trial on volunteers,
00:41and they're working on a larger one to test effectiveness and safety.
00:44We could really have artificial blood by 2030.
