«In recent years, researchers in Cambridge led by Dr Kiyoshi Nagai at the Medical Research Council's laboratory of molecular biology have produced a human haemoglobin modified at key sites to resemble the crocodilian protein.
The resulting protein was still 96% human and so does not trigger the body's immune system but is able to handle oxygen like crocodile haemoglobin. Such haemoglobin could one day be injected into victims of massive blood loss to quickly deliver large amount of oxygen to dying tissues. Crocodile haemoglobin works in a similar way to the human protein, but responds strongly to the bicarbonate produced by tissues consuming oxygen.»

Yow!! I hope this gives me superpowers!!
