What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

The Big Idea for Saturday, March 10, 2012

"I feel my own conscious, rational self isn't calling the shots anymore," science writer Jena Pincott observed during her pregnancy. "I'm inhabited by urges and appetites that are not my own," she writes in her recent book, Do Chocolate Lovers Have Sweeter Babies?: The Surprising Science of Pregnancy. And so Pincott asked herself: "I'm not in control, so who is?"

It's the fetus that's in control, at least some of the time. The fetus manipulates its mother's body before it is born, and even after it is born. The phenomenon known michrochimerism involves fetal cells passing through the placenta and establishing cell lineages within the mother.

What does this mean? "When fetal cells are good, they are very, very good," Pincott explains in an introductory post to her new Big Think blog Paleo Parenting, which covers the science of raising children. Fetal cells have been observed to migrate to a part of a mother's body to repair injuries. "They may help protect mothers from some forms of cancer," Pincott adds. "They may cross the blood-brain barrier and potentially generate new neurons."

While experimental research in this field is still in its early stages, Pincott explores the awesome potential for harvesting fetal cells in this Big Think lesson.
