How the hell did we grew so much is so little time? This video by National Public Radio has the answer.

Edinburgh University researchers develop artificial blood from bone marrow stem cells! 98% of people can receive (O-negative). Science win.

30 Oct

Researchers at Edinburgh University have developed a new type of faux blood that could be ready for human testing in as little as two years.

Their technique involves growing stem cells taken from the bone marrow of healthy adults into a new material thats very close to the red blood cells grown naturally in humans. Moreso, the artificial blood they create would be the rare, and highly sought after, type O-negative which can be used in 98% of patients.

And it would be guaranteed to be free of infections like HIV or Hepatitis. The researchers are confident that their process has been perfected to the point where clinical trials could begin in just 2 years.

But since their technique only produces red blood cells, they’d have to then work with other researchers to combine it with artificial hemoglobins before the artificial blood could become part of regular hospital use. A process that could take up to another 10 years.
