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.

Is Exercise the Key to Immortality?

What's the Latest Development?

For the first time, scientists are beginning to understand how exercise works on the body and mind to make us healthier. It seems that physical exertion helps promote autophagy, derived from the Greek for 'self-eating', which is the body's process of recycling worn-out or malformed proteins. In research conducted in Texas, mice which ran on treadmills produced more autophagosomes in their muscles and mice who could not produce autophagosomes became more easily fatigued and processed less sugar from the bloodstream.   

What's the Big Idea?

Exercise is about as close as it comes to a panacea, protecting the body and mind against a host of ailments. And if autophagy is the process by which exercise benefits us, then we may have found the first step to prolonging life in dramatic fashion. Autophagy's process of recycling proteins helps slow the aging process by getting rid of "wonky" mitochondria, the power stations of the cell, and would reduce free-radical production resulting from the oxidation of molecules in our bodies.
