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.

Japan Creates a Pig that Grows Human Organs

What's the Latest Development?

Animals called chimeras, which grow human organs ranging from the liver to the brain, are under development in Japan as a way of harvesting organs for transplant. Bioethicists have already voiced concerns over animals that share uniquely human characteristics, including animals with human sperm or eggs or a non-human primate with a humanized brain. "The Japanese team claims that their technique rules out the possibility of creating a pig with human gonads or brain, but that remains an untested claim. If the technique fails, the boundary will be crossed."

What's the Big Idea?

The UK Academy of Medical Sciences has already weighed in on the issue of animals containing human material in a report published two years ago. The report concluded that most research on chimeras is permitted under existing laws, but it did identify some experiments which should not yet be done. The goal of chimeras, for now, is to create human organs available for transplant. "There are also looming questions of animal welfare. To satisfy the demand for organs would require the sacrifice of about a million pigs a year. Of course, any ethical concerns must be weighed against the potential benefits for human health and life."
