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.

Doctors Say Humans Ready for Suspended Animation

May 27, 2014, 10:01 AM

What's the Latest?

By dramatically cooling down the bodies of trauma patients from the inside, surgeons at UPMC Presbyterian Hospital in Pittsburgh will be the first to use suspended animation techniques to keep patients alive during critical operations. "A team of surgeons will remove all of the patient's blood, replacing it with a cold saline solution... This will slow down the body's metabolic functions, significantly reducing its need for oxygen. ... A state of profound hypothermia will be induced, at about 50ºF (10ºC), to provide a 'prolonged period of cardiac arrest' after extensive bleeding. In other words, clinical death."

What's the Big Idea?

It was twenty years ago that researchers first proposed the idea of rapidly inducing hypothermia to buy time for surgeons whose patients were bleeding out on operating tables. Then in 2000, researcher Peter Rhee successfully tested the suspended animation techniques on pigs. Because patients will not be able to give informed consent, citizens of Pittsburg are asked to opt out of the procedure ahead of time if they wish. If suspended animation technology develops further, it could eventually be used on astronauts, allowing them to complete long space missions with fewer resources. In a state of suspended animation, the body would require very few calories.
