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.

Giant Viruses May Be a New Domain of Life

What's the Latest Development?

A pair of French scientists have discovered record-breaking viruses that are larger than many bacteria and even some eukaryotic cells. But more impressive than their size is their composition. Just seven percent of their genetic make up matches those cataloged in existing genetic databases. "This is a major discovery that substantially expands the complexity of the giant viruses and confirms that viral diversity is still largely underexplored," says Christelle Desnues, a virologist at the French National Centre for Scientific Research in Marseilles, who was not involved in the study.

What's the Big Idea?

The researchers dubbed their find the Pandoravirus because it may unlock secrets about the evolution of life at the cellular level. It has long been suspected that giant viruses evolved from cells. If that is true, the ancestors of Pandoraviruses must have been very different from the bacteria, archaea and eukaryotes we have today. “We think that at some point, the dynasty on Earth was much bigger than those three domains,” said Chantal Abergel, one of the researchers involved in the study. It seems some cells gave rise to modern life, and others survived by parasitizing them and evolving into viruses.
