Japanese researchers at Yamaguchi University have published new findings in The Anatomical Record revealing that the differential flexibility between cats' thoracic and lumbar spines — not a single smooth rotation — is the key anatomical mechanism behind the famous cat righting reflex. The study, which combined cadaver spine mechanics with high-speed video of live cats, resolves a physics paradox that has fascinated scientists since Étienne-Jules Marey's 1894 photographs first appeared to show cats violating the conservation of angular momentum.
