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.

Making Drought Resistant Crops

What's the Latest Development?

By altering a plant's hormones, scientists have discovered a way to make crops more resistant to drought. Drought resistance is a natural response in plants that involves the production of abscisic acid, a stress hormone which guards leaves against water loss and reduces plant growth to slow water consumption. A team of scientists at the University of California, Riverside, have found a way to switch on plant receptors that produce the beneficial hormone.  

What's the Big Idea?

If the laboratory work at Riverside can be transferred to the field, the gains could be substantial. Drought resistant crops could help fight hunger by allowing rain-scarce regions to produce more food. The discovery of abscisic acid in 2009 was heralded as one of the year's major scientific advances due to the importance of the hormones in helping plants cope with stress. Crops that are able to resist drier conditions could also help populations better adapt to climate change.
