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.

A Breathalyzer for Cancer

What's the Latest Development?

A California start up has developed a breath test that can diagnose lung cancer with a 83 percent accuracy and distinguish between different types of the disease. The procedures which currently exist to test for lung cancer, which is the leading cause of cancer deaths worldwide, result in too many false positives, meaning unnecessary biopsies and radiation imaging. The new devices works by drawing breath "through a series of filters to dry it out and remove bacteria, then [carries it] over an array of sensors." 

What's the Big Idea?

The company is now testing a version of the machine 1,000 times more accurate than its latest model, which could increase the accuracy of diagnoses to 90 percent, the level likely needed to take the device to market. Because the machine is not specific to a particular group of chemicals, the breath tester could, in principle, test for any disease that has a metabolic breath signature, for example, tuberculosis. "A breath signature could give a snapshot of overall health," says the company's founder, Paul Rhodes.
