Squid Protein Could Help Brains 'Talk' to Computers

Scientists have discovered a new feature of a protein called reflectin, found in a group of animals called pencil squid. It turns out reflectin conducts protons and may be able to bridge the communication divide between cells and biomedical implants. It's ability to move around these positive charges and it's "tunability," or versatile nature, could be used to build implants and prosthetics that can more easily communicate with the human body. The fact that it is biological and flexible means that it may be better than existing materials for integrating into the human body, and with a lower chance of being rejected, the researchers (from the University of California, Irvine) said. And since it is a protein, it could be modified in other desirable ways, such as possibly being able to biodegrade after it is done serving a useful purpose, which could help patients avoid additional surgeries.
