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.

Modern Vampires: Using the Blood of the Young to Reverse Aging

What’s the Latest Development?

At a recent conference among neuroscientists, one researcher unveiled a study in which old mice were injected with the blood of younger mice. Results of the study “found that blood from young mice reversed some of the effects of ageing in the older mice, improving learning and memory to a level comparable with much younger animals.” Additional work that involved injecting older mice with blood plasma from two-month-old mice found that the old mice were able to solve mazes much better than their non-injected counterparts.

What’s the Big Idea?

One of the most important discoveries from this study was that the transfused older mice experienced a “20% increase in connections between brain cells.” Additionally, the number of stem cells increased in their brains. If the results of the study can be applied towards people, researchers hope “the technique could one day help people stave off the worst effects of ageing, including conditions such as Alzheimer's.”  While there is a huge jump between working with mice and working with humans, researchers foresee the possibility that “people in their 40s or 50s could take therapies based on the rejuvenating chemical factors in younger people's blood, as a preventative against the degenerative effects of ageing.”
