What hibernating bears and 'couch potato' cavefish are teaching us about blood clots and fatty liver disease
Mar 6, 2024
Deboki Chakravarti, an expert on animal extremities and their health implications, dives into the fascinating survival strategies of hibernating bears and Mexican cavefish. She explains how bears avoid blood clots during hibernation and the potential treatments this offers for humans. The conversation extends to the cavefish, revealing their unique adaptations to starvation and darkness that could inform fatty liver disease research. Deboki also humorously ponders the strange case of a mushroom growing on a frog, highlighting the complexities of defining species.

The Evolution of Life on Earth
Earth's early environment was predominantly aquatic, forming a primordial soup that set the stage for life to evolve over billions of years. Initially, single-celled organisms emerged, leading to the development of multicellular plants and animals, and eventually, humans. Despite the vast differences in appearance and behavior among species, there is a significant genetic connection, suggesting that studying other species can offer insights into human biology and health. This evolutionary relationship highlights the potential benefits of examining the unique characteristics of various organisms to improve our understanding of human physiology.
