Weekly roundup: TEDx edition

Yesterday I attended TEDxLakeComo, historically the first TEDx Italian event now in its second edition. TEDx is a spin-off of the TED global conference: a program of independently organized events which respect the spirit of TED: ideas worth spreading.
I think the power of TED and TEDx is in its wide variety of topics and speakers, that maintain are however connected in a single thread (at least in this edition). In a single day I attended talks about cloning, robotics, climate change, pandemics, and the free market. The world problems - energy, pollution, climate, economics -  are all more interrelated than I thought.

Here are my original articles for this week, published on Web Builder Zone.
