Proper nutrition can unleash amazing powers, moms have always assured us, frequently citing Popeye the Sailor Man as evidence. Now, two ÌÒÉ«ÊÓƵ scientists have confirmed just how potent some nutrients can be.

Although the researchers discovered this phenomenon in worms, the research could have implications for future studies into human fertility and reproductive development.
