U.S. Researchers Develop DNA Encryption to Secure Engineered Cells Against Theft
A team of U.S. researchers has introduced a novel approach to secure engineered cells using DNA encryption. This method involves scrambling the DNA of a cell, rendering its instructions non-functional until decrypted with a precise sequence of chemicals. The Centers for Disease Control and Prevention and the Department of Homeland Security have reported increased theft and smuggling of high-value biological materials, including engineered cells, which could be misused for bioweapons or environmental harm. Traditionally, these cells are protected by physical security measures, but the new genetic combination lock offers a more robust solution. The encryption process was tested through an ethical hacking exercise, achieving a 0.2% success rate in unauthorized access attempts, close to the theoretical target of 0.1%.
