What goes wrong in older eggs?

...rs devised a strategy with Drosophila to mimic the aging process that human eggs normally undergo. In humans, each female is born with all the eggs that will develop during her lifetime. As a woman ages, so do her eggs. Drosophila females, however, constantly produce and lay newly formed eggs. "We normall...

Study on worlds oldest monkeys may explain age-related mental decline, Scientists say
