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.

Regenerative Medicine Takes Cues from Animal Kingdom

February 16, 2013, 4:20 PM

What's the Latest Development?

In looking for ways to regrow lost or damaged limbs in humans, scientists are taking cues from the animal world where several species are known to effectively regenerate certain body parts. "Zebrafish, blue-and-white-striped fish that grow to be about 1.5 inches long, can regrow fins. To study how, scientists at Duke University Medical Center generated zebrafish with depleted levels of cells responsible for creating bone. ... Learning more about this process could aid the development of therapies for bone injury or loss in humans."

What's the Big Idea?

Besides promoting certain types of cell growth, genetic manipulation may provide a method for regenerating human tissues. Several years ago, researchers at The Wistar Institute discovered that inactivating a single gene allowed holes in mouse ears to close without scarring. "The researchers determined that this breed of mice has an inactive version of a gene involved in regulating cell growth and division. The finding offers new insight into regeneration in a mammal and could guide the direction of future research."
