It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising approaches to follow up such considerations. An international research team led by the Biophysics Department of the GSI Helmholtzzentrum in Darmstadt now has found decisive indications of the possible benefits of artificial hibernation for radiation resistance. The research partners from Germany, Japan, Italy, the UK and the USA have recently published their results in „Scientific Reports“, a journal of the Nature Publishing Group.
