Regrowing the human body
It’s aaalive! Behold, these advancements in science and tech allow us to create human body parts.

You can grow new brain cells. Here's how
10 minutes 54 seconds
Can we, as adults, grow new neurons? Neuroscientist Sandrine Thuret says that we can, and she offers research and practical advice on how we can help our brains better perform neurogenesis—improving mood, increasing memory formation and preventing the decline associated with aging along the way.
A new way to grow bone
14 minutes 38 seconds
What does it take to regrow bone in mass quantities? Typical bone regeneration -- wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body -- is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.
Growing new organs
17 minutes 35 seconds
Anthony Atala's state-of-the-art lab grows human organs -- from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that "prints" human tissue.
Body parts on a chip
13 minutes 9 seconds
It's relatively easy to imagine a new medicine -- the hard part is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications -- perhaps even custom cures made for one specific person.
The potential of regenerative medicine
19 minutes 11 seconds
Alan Russell studies regenerative medicine -- a breakthrough way of thinking about disease and injury, using a process that can signal the body to rebuild itself.
