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.

China Prints Human Liver Cells Using 3-D Printer

What's the Latest Development?

Using a 3-D printer, researchers at a Chinese university have printed live human liver cells with high rates of success, ensuring that 90 percent of the cells leave the printer alive. The liver cells are made from a special material called hydro-gels, a watery substance rich in nutrients. "Before printing, researchers culture the cells in a large volume and blend them with hydro-gels. The mixture is then used as the raw material of cell printing." Unlike printing solid physical objects, such as a cup in which material must be printed closely together, scientists must leave space for cells to grow as they divide and reproduce.

What's the Big Idea?

The liver cells printed by Chinese scientists have been shown to function exactly like human livers in that they break down toxins, metabolize, and secrete. Given the 1.5 million people who need an organ transplants in China each year, researchers are hopeful that, given more research, a path toward regenerative medicine can be found. This budding field of medicine, in which organs are grown in laboratories and then transplanted into patients, holds great promise in revolutionizing surgery and human longevity. Currently, less than one percent of Chinese citizens requiring organ transplants receive them.
