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.

Sleep Deprivation Linked to Serious Disease

December 8, 2012, 2:30 PM

What's the Latest Development?

A number of new studies suggest an intimate relationship between a good night's rest and diseases like Alzheimer's and post-traumatic stress disorder. By disrupting connections important to daydreaming and introspection, sleep deprivation affects the same neural network as Alzheimer's, perhaps making the brain more susceptible to the disease. In the case of PTSD, blocking certain proteins in the amygdala during sleep has been seen to ease traumatic memories. Researchers hope that by continuing to study the effects of sleep on memory, new treatments can be discovered. 

What's the Big Idea?

One in five American adults show signs of chronic sleep deprivation and, ironically, losing sleep so you can accomplish tasks during the day will make you less effective at actually accomplishing them. Memory and learning are greatly affected by the amount of sleep you get. "Just two hours of lost sleep in one night can keep the hippocampus from turning information from the day before into long-term memories." Loosing sleep also makes accidents more likely. One study showed that teenagers who slept eight hours or more were 60% less likely to get injured while playing sports.
