Protein from Whales Might Make Better Synthetic Blood

"Have you ever wondered how whales stay underwater for up to two hourswithout coming up for air? It’s because they use a highly stable protein called myoglobin, which stores oxygen for a long time, to power their muscles. Now researchers from Rice University are working with the protein in order to make synthetic blood for humans, according to a study published last week in the Journal of Biological Chemistry."
