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.

How Fasting Could Help You Live Longer, Healthier

January 12, 2013, 11:30 AM

What's the Latest Development?

Intermittent fasting could boost your biological defenses while reducing caloric intake, resulting in a healthier and longer life, according to a wide-ranging series of experiments done on animals and humans. Mark Mattson, head of the National Institute on Aging's neuroscience laboratory, "thinks that intermittent fasting acts in part as a form of mild stress that continually revs up cellular defenses against molecular damage." Levels of molecules known as 'chaperon proteins,' for example, which are known to prevent the incorrect assembly of other cellular molecules, are known to increase as a result of fasting. 

What's the Big Idea?

The world's religions have long maintained that fasting is good for the soul, and modern science, which generally locates the soul in the mind, has found that the occasional deprivation of food effectively guards against mental disease. In one experiment Mattson performed on lab mice, he found that "fasting mice have higher levels of brain-derived neurotrophic factor (BDNF), a protein that prevents stressed neurons from dying." Low levels of BDNF have been linked to everything from depression to Alzheimer's, although it is still unclear whether these findings reflect cause and effect.
