Gravitational Research Branch
NASA-Ames Research Center
Dr. Alan R. Hargens has been the Principal Investigator on experiments
involving cardiovascular and musculoskeletal adaptations of animals and
humans to gravity. He has studied giraffes in Africa and arboreal snakes
on the Amazon River to understand how their tissues have adapted to high
and variable levels of gravitational stress. His recent research focuses
on development of new forms of artificial gravity to provide physiologic
levels of stress for long-duration space travel without the need for a
centrifuge. He has recently patented noninvasive techniques for measuring
intracranial pressure and understanding spinal responses to weight bearing.
