Even though the combination of affluence and fertility drugs has raised the age at which many women give birth, children born to older women continue to suffer a disproportionately high rate of birth defects and genetic disease. Many of these problems result from the degradation of the area of the region of the egg around the nucleus.
To correct for those problems, a team of Japanese researchers has implanted the nucleus of an older woman's egg into the egg cell of a younger donor. This may fix the problem, but it also moves medicine closer to the ethically challenging creation of a person with three biological parents.

While some may imagine that obesity begins once a child is tall enough to reach the top shelf where mom and dad keep the cookies, a new study points to an even earlier age that jump starts obesity: infancy.
