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.

How Nanoparticles May Transform Cancer Treatment

March 9, 2013, 2:27 PM

What's the Latest Development?

A team of Swedish scientists have created a nanoparticle capable of delivering non-toxic cancer-treatment drugs directly to tumors in the body which are both biodegradable and traceable using MRI machines. "The method makes nanoparticles spontaneously build themselves up using customized macromolecules. ... The scientists filled nanoparticles with the chemotherapy drug doxorubicin (DOX), which is used to treat bladder, lung, ovarian and breast cancer. In experiments on cultured cells, they showed that the particles themselves are not harmful but can effectively kill cancer cells after being loaded with the drug."

What's the Big Idea?

The new system should prove especially useful for cancers that are difficult to treat with chemotherapy, including brain, pancreatic and drug-resistant breast-cancer tumors. "In the long term, the research can result in tailored chemotherapy treatments that seek out tumor cells. This would enable the toxic drug to be delivered more specifically to the tumor, making the treatment more effective while reducing side effects." Scientists aim to give nanoparticles a homing function so that the cancer drug is as effective as possible and can be transported to the right place.
