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.

Eric Green:  So Moore’s law is sort of the law of the computer industry that says compute power doubles every 24 months or so.  And, you know, that’s sort of put out there by experts and technology development is sort of, you know, the prototype.  That’s the thing that you really shoot for with Moore’s law but nobody ever keeps up with Moore’s law except the computer industry.  So saying we actually track and have been tracking really, you know, the past 15 years in terms of the cost for DNA sequencing.  And trying our best to keep up with Moore’s law and actually we did keep up with Moore’s law really quite effectively near the end of the genome project and even in the number of years for four or five years after the genome project using the old fashioned method that we used to use for DNA sequencing but we had sufficiently industrialized those methods that actually allowed us to keep up with Moore’s law.

And then what happened?  About 2007 our major groups switched over to these fancy new methods.  They’re called next generation DNA sequencing methods and almost overnight and has just continued to do it up to the present time they outstripped Moore’s law by far.  And it’s really been truly remarkable.  The cost of DNA sequencing has plummeted tremendously so that that first human genome sequence that was completed ten years ago cost a billion dollars and now we can sequence a human genome today in a matter of a day or two and it costs well under ten thousand dollars, really just a few thousand dollars.  And if you follow the curves which we’ve been following you can see particularly the last six years we have out paced Moore’s law by far.

So among the many exciting developments in genomics really continues to be new technologies for sequencing DNA.  We’ve come a long way and have incredibly powerful methods today.  There’s new ones coming and we continue to invest in the development of new technologies because we see the importance of it.  There’s a particular new methodology that’s getting a lot of attention in the genomics community these days.  It’s called nanopore sequencing.  It really is with molecules that sit in lipid bilayers and the strands of DNA sort of get pulled through it and literally we’re able to detect every single base on that DNA ladder one at a time as it gets pulled through the nanopores.  It’s just way cool.

But what’s particularly cool about is is that the technologies can be reduced to really small form and one of the companies that’s manufacturing it is releasing an instrument this year that basically looks like a USB device.  In fact it is a USB device.  It’s a little bit bigger than a thumb drive.  And literally it plugs into the USB port of a laptop computer and I haven’t seen it operate yet but I’m told it can sequence a human genome in something like a day.  We’ll have to see when it’s released how it really performs.  But the notion, you know, and whether it’s that company or whether it’s this year or whether it’s another company or it’s another year – it’s not science fiction to believe that we will have these little USB devices sitting in our laptop that can read out human genome sequences in the next year or two or three.

One of the things I think is particularly cool with this first company that’s launching these USB devices is that the company tells me that the USB device that will sequence a human genome will work equally well in a PC or a Macintosh computer which makes me think they’ve thought of everything.
