Chapters
The episode explores the possibility of human hibernation for deep space travel. The hosts discuss the concept with Ryan Sprenger, a Senior Research Physiologist at Fauna Bio, who is researching the feasibility of inducing torpor in humans.
  • Hibernation is a state of metabolic and body temperature depression.
  • Animals hibernate to conserve energy during periods of resource deprivation.
  • Ryan Sprenger's company, Fauna Bio, studies extreme animal physiology for drug development and space health.

Shownotes Transcript

How close are we to enabling  astronauts to go into deep sleep for long space journeys? Neil deGrasse Tyson, Chuck Nice, & Gary O’Reilly team up with Ryan Sprenger, Senior Research Scientist at Fauna Bio, to explore whether humans can hibernate like animals do.
