[Best of] August Krogh's Nobel Prize: Respiration is still a key research topic.

More than 100 years ago August Krogh received the Nobel Prize for showing how oxygen is transported from the lungs through the blood into the small capillaries in the muscles. Details of the mechanism and how it is regulated are still central topics of research a hundred years after and understanding respiration is still a matter of life or death. In this interview science journalist Jens Degett had the opportunity to talk to, one of the world's leading physiologists professor Christopher Ellis from the University of Western Ontario (Canada) about how August Krogh's 1920 Nobel Prize greatly influences physiological research even 100 years later. In addition to Nobel Prize class research, August Krogh founded one of the first biomedical companies in Denmark. The company would later become Novo Nordisk, which is now among the world's largest manufacturers of biomedicine and insulin. Photo credit: Jens Degett
