What’s the News: Since the 1950s, it’s been generally accepted that women are born with all the eggs they will ever have. One gets doled out with each menstrual cycle, and when they run out, you get menopause.

Now, working with donated tissue, researchers have found similar cells in human ovaries.

Headlines hyping the find have been spreading across the web, and we feel compelled to point out that this paper doesn’t mean that we will be able to grow fresh new eggs in Petri dishes, and it doesn’t prove that in real, live women these cells actually mature into eggs that can develop into offspring. It does, however, provide an interesting chance to see whether egg production by these cells can be jump-started using drugs.
