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 Sunday, November 10, 2013

It appears we may now be able to add another major cancer to the list of neoplastic diseases caused by a microbe. As Kas Thomas points out in today's lesson, it's beginning to seem pretty clear that CRC is, at least in part, a bacterial disease.

This new understanding might also suggest novel prevention concepts. As Thomas writes, "if you want to reduce your risk of colorectal cancer, you might do well to cut down on alcohol, red meat, and other aspects of the western diet that are known to be associated with colon cancer; and you might just want to buy yourself a big bottle of mouthwash. For all we know, the mouth (not the colon) is where Fusbacterium gets its start. Why not kill it at the source?"

There's also a role for fecal transplants, antibiotics, and/or probiotics in the prevention and management of the ailment.
