 In 2012, the state of Colorado legalized cannabis, part of what has fast become a multibillion-dollar global industry for all things weed-related, from vape pens to brownies and beyond. But to say that we've legalized marijuana is subtly misleading -- what we've really done is commercialized THC, says activist Ben Cort, and that's led to products that are unnaturally potent.

Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This plan is one of the first ideas from The Audacious Project, TED's new initiative to inspire global change.) Watch »  Geneticist Steve McCarroll wants to make an atlas of all the cells in the human body so that we can understand in precise detail how specific genes work, especially in the brain. In this fascinating talk, he shares his team's progress -- including their invention of "Drop-seq," a technology that allows scientists to analyze individual cells at a scale that was never before possible -- and describes how this research could lead to new ways of treating mental illnesses like schizophrenia.
