Getting old is inevitable, but scientists at the University of California San Diego (UCSD) may be one step closer to being able to delay the aging process.
cells aged because of a gradual decline in the nucleolus, a round body located in the nucleus of a cell, the scientists learned, by using techniques including microfluidics and computer modeling.
Scientists said that the cells go down one of two paths -- nuclear or mitochondrial -- early in life, and they continue with the aging route until they ultimately decline and die.
"This is an aging path that never existed, but because we understand how it is regulated, we can basically design or regulate a new aging path," Hao told CNN.
