The brain may be able to repair itself – with help

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.”

The unexpected benefit of celebrating failure

“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.

Gene editing can now change an entire species – forever

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?
