Can kitchen waste provide the blueprint for human tissue repair?

This scientist makes ears out of apples | Andrew Pelling · 7:06 · Video: TED · Watch at the source

In short: Biohacker Andrew Pelling is using the cellulose structure of common apples to grow lifelike human ears. This demonstration explores the potential of using simple, organic materials to create affordable medical solutions.

Pelling treats nature as hardware, focusing on the simplest materials available—even those found in the garbage. By leveraging the specific cellulose structure that gives an apple its form, he has pioneered a method to grow human ear replicas.

The project serves as a proof of concept for a future where body parts could be repaired or augmented using materials made in a kitchen. The goal is to move toward a model of medical reconstruction that is both safe and significantly cheaper than current methods.
