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.

A New Kind Of Biological Clock Could Turn Back Time

What's the Latest Development?

UCLA genetics and biostatics professor Steve Horvath looked at over 350 biomarkers of age in the human body and measured them for certain chemical changes that occur from pre-birth to age 101. Through this, he was able to calculate the biological age of organs, tissues and cells, and found that in most cases they matched their chronological age. One key exception was breast tissue, which he says "is about two to three years older than the rest of a woman's body." He also noted that tumor tissue is, on average, 36 years older than healthy tissue, which could help explain why cancer risk grows as people age. 

What's the Big Idea?

For scientists, understanding why people age has always been a challenge. Past attempts to identify an accurate biological clock have focused on, among other things, hormones and chromosome telomeres. Horvath's method is the first to, as he puts it, "reliably [keep] time across the human anatomy." In addition to providing insights into cancer research, the findings -- which were published in the latest edition of Genome Biology -- could help with efforts to slow down or even reverse aging.
