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.

Nano-Machine May Produce New Drug Molecules

January 12, 2013, 4:00 PM

What's the Latest Development?

A team of scientists at Manchester University, UK, have created a microscopic machine capable of building proteins similar to ones found naturally in the body's many cells. Just a few millionths of a millimetre in size, the minute machine resembles a ring threaded on a rod. "A 'reactive arm' is attached to the ring and works its way down the rod, removing and stacking the amino acid units bound to the rod. A key point is that the sequence for a new polymer chain comes from the scientists. It is controlled by the chemical groups placed along the rod structure." 

What's the Big Idea?

The ultimate goal of the machine is to synthesize mew drug molecules, not unlike how large quantities of medicines are currently made. "[J]ust as insulin for diabetics today is produced in vast vats by engineered microbes, so in the future the Manchester team envisages containers carrying millions upon millions of their artificial machines all churning out the programmed molecules." And because the scientists' machine is not limited by nature's building blocks, they hope to be able to construct new kinds of plastic, catalysts and pharmaceuticals.
