TED: This scientist makes ears out of apples | Andrew Pelling

The video explores the creative use of garbage in scientific research, led by Andrew Pelling. He discusses his passion for hacking old electronics and how this approach fosters creativity in his university-based biological research lab. Pelling shares innovative experiments, such as growing human cells in apple scaffolds and using asparagus for nerve regeneration. The lab's open-source approach and mission-driven company aim to make these techniques accessible. The video concludes with a call to embrace unconventional ideas and collaboration in science.
