Scientists at the University of Liverpool have shed new light on how diving mammals, such as the sperm whale, have evolved to survive for long periods underwater without breathing. This new research could help improve understanding of a number of human diseases where protein aggregation is a problem, such as Alzheimer's and diabetes, and could inform the development of artificial blood substitutes.

The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), identifies a distinctive molecular signature of the oxygen-binding protein myoglobin in the sperm whale and other diving mammals, which allowed researchers to trace the evolution of the muscle oxygen stores in more than 100 mammalian species, including their fossil ancestors.
