Scientists go to zoo, find that cell size, not body size, affects lifespan
Researchers in Israel, Canada, and Germany have found that animals with larger pancreatic cells tend to age faster, while those with smaller such cells seem to live longer.
They came to this “shockingly beautiful and unexpected” correlation, said Yuval Dor, who studies developmental biology at The Hebrew University’s Hadassah Medical School in Jerusalem, after studying the pancreases of 24 mammalian species, from the smallest, a shrew, to the tallest, a giraffe. T
The findings were published on Monday in the journal Developmental Cell.
Previously, scientists had thought that after birth, most mammals’ organs, including the pancreas, grow by cell ...
