Scientists have recently made a breakthrough in genetic engineering by discovering a way to program bacteria with the CRISPR-Cas system to recognize a wide range of viruses, providing a new way to combat disease.

CRISPR-Cas, which stands for Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR associated, is a system of proteins and genetic elements found naturally in bacteria. Scientists have recently been able to reprogram the bacteria to recognize a wide range of viruses, allowing it to act as a defense mechanism against infection. This breakthrough could lead to new treatments for a variety of diseases and other medical applications.
