Can humans ever harness the power of hibernation?

Scientists want to know if astronauts can hibernate during long spaceflights. First, they need to understand what hibernation is

Dear Editor,

In reference to the article by Ben Panko “Can humans ever harness power of hibernation?” (Jan 18th, 2017) I would like to draw your attention to a series of revolutionary works on hypothermia from the Belgrade School of Physiology in 1950s that is often neglected (probably due to its very early dates). These studies were initiated by the founder of the School prof. Jean Giaja (1884-1957), member of Serbian and French academies of sciences, who discovered the method of hypercapnic hypothermia (spontaneous cooling of a homeotherm to a body temperature as low as 15C  in a closed vessel). This was published as early as 1940 (Bull Acad Serbe Sci Arts. 1940 6:65; C R Hebd Seances Acad Sci. 1940 210:80). These papers were written in Serbian and in French respectively. However, Giaja also published in English and we would like here to emphasize only one, the paper in Nature Giaja & Radulovic Survival of the heart following deep hypothermia. Nature. 1956 178:1286). This research raised a whole series of seminal studies by Giaia’s student Radoslav K. Andjus (1926-2003) who managed to further cool lab rats to body temperatures near ZERO and resuscitate them. Dr Andjus also became member of the International Astronautic Academy (Biology section) for obvious reasons.  We present here a list of selected papers in respected journals of Dr Andjus’ studies, We hope the titles speak for themselves.
