In a December article for The New Republic, "The Grayest Generation: How Older Parenthood Will Upend American Society," the magazine's science editor Judith Shulevitz points out how the growing trend toward later parenthood since 1970 coincides with a rise in neurocognitive and developmental disorders among children.

A biology lab at Loyola University was able to regenerate this elbow joint in a chicken embryo. The research could mean big possibilities for scientists looking to coax the human body into regenerating its own joints.
In a biology lab at Loyola University New Orleans, something miraculous happened — something no scientist had seen before. Biology professor Rosalie Anderson and her undergraduate students cut a tiny hole to remove just the elbow joint of a chicken embryo’s wing. Eighteen hours later, a new joint amazingly grew back.

For the first time, the nation's pediatricians are wading into the controversy over whether organic food is better for you – and they're coming down on the side of parents who say it is, at least in part.
Men, did you know that we hurt people when we chose not to learn? Aldous Huxley said, “We can only love what we know, and we can never know completely what we do not love.”
That Huxley quote always reminds me of the never-ending responsibility to learn about the people I claim to love. Intimacy comes out of the scrutiny of our desires, shames and delights. Therefore, loving is not just learning how to be vulnerable; it’s being vulnerable enough to learn.
The National Institutes of Health says it will relocate 110 of its chimpanzees from the University of Louisiana at Lafayette's New Iberia Research Center and to stop using the animals for biomedical testing.
The Advocate reports that the plan was announced Friday.
The move comes as NIH decides how best to implement recommendations that call for more stringent standards on biomedical research using chimpanzees, considered the closest relative to humans in the animal kingdom.
Facebook is taking its campaign to boost organ donations to Canada and Mexico this week, four months after its premiere.
The feature allows Facebook users to tell their friends and family that they're registered organ donors. It also directs people who aren't signed up as organ donors to the official registries where they live.

Every year, we dutifully report on the annual Trust for America's Health and Robert Wood Johnson Foundation state obesity rankings, and every year, it's a similar story — a handful of southern states, on the whole, are the biggest. (It's Mississippi, Louisiana, and West Virginia in 2011, in case you were wondering.)
A study at LSU Health Sciences Center New Orleans has found that the popular dietary supplement ginkgo biloba doesn't improve mental function in patients with multiple sclerosis.
Neurologist Jesus Lovera did the study on 120 people because an earlier, smaller study had seemed promising. Ginkgo is taken by many people who have the disease, which attacks the myelin that insulates nerve fibers. About 40 to 60 percent of multiple sclerosis patients develop problems with memory or other cognitive functions.

Yes, we love salt. It makes everything taste better. But as a society, we're eating way too much of it. And, so are our children.
A new study from researchers at the Centers for Disease Control and Prevention shows that children in the U.S. between the ages of 8 and 18 are eating, on average, 3,387 mg per day. That's about the same amount as adults. But it's a lot more than the 2,300 mg daily limit recommended by the federal dietary guidelines.
