Through treating everything from strokes to car accident traumas, neurosurgeon Jocelyne Bloch knows the brain’s inability to repair itself all too well. But now, she suggests, she and her colleagues may have found the key to neural repair: Doublecortin-positive cells. Similar to stem cells, they are extremely adaptable and, when extracted from a brain, cultured and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. “With a little help,” Bloch says, “the brain may be able to help itself.”

“Great dreams aren’t just visions,” says Astro Teller, “They’re visions coupled to strategies for making them real.” The head of X (formerly Google X), Teller takes us inside the “moonshot factory,” as it’s called, where his team seeks to solve the world’s biggest problems through experimental projects like balloon-powered Internet and wind turbines that sail through the air.

The CRISPR gene drives allow scientists to change sequences of DNA and guarantee that the resulting edited genetic trait is inherited by future generations, opening up the possibility of altering entire species forever. More than anything, the technology has led to questions:
How will this new power affect humanity?
What are we going to use it to change?
Are we gods now?

We’re heading for a world population of 10 billion people — but what will we all eat? Lisa Dyson rediscovered an idea developed by NASA in the 1960s for deep-space travel, and it could be a key to reinventing how we grow food. Find out more by watching the video below.

Neuroengineer Ed Boyden wants to know how the tiny biomolecules in our brains generate emotions, thoughts and feelings — and he wants to find the molecular changes that lead to disorders like epilepsy and Alzheimer’s.
