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.

Researcher Locate the Left-Handed Gene

September 14, 2013, 1:00 PM

What's the Latest Development?

A European study may have found the cause of people's strong disposition toward being right-handed, a tendency not seen nearly as strong in animal species. In experiments led by the University of St. Andrews, researchers were interested in understanding which genes might have an influence on handedness (right versus left), in order to gain an insight into the causes and evolution of handedness. What they found were correlations between handedness and a network of genes involved in establishing left-right asymmetry in developing embryos.


What's the Big Idea?

To date, the reason for our strong preference in using our right hand, with around 90 percent of the adult population being right-handed, mostly remains a mystery. William Brandler, a PhD student in the MRC Functional Genomics Unit at Oxford University, said: "The genes are involved in the biological process through which an early embryo moves on from being a round ball of cells and becomes a growing organism with an established left and right side." The researchers suggest that the genes may also help establish left-right differences in the brain, which in turn influences handedness.
