A New Technology Can be Used Instead of Antibiotics to Kill Superbugs
Dr. Timothy Lu, an associate professor in biological engineering at the Massachusetts Institute of Technology, found a new potential way to kill superbugs with a DNA editor called CRISPR-Cas9. The Wall Street Journalreported that Dr. Lu said: “is is basically a molecular scissor” that can snip bacterial genes that make bacteria drug-resistant, killing the bug in the process.  The technology combines bacteriophages and CRISPR-Cas9 to target drug-resistant genes. What is CRISPR? CRISPR is used to edit or delete genes from living cells.  “CRISPR” means Clustered Regularly Interspaced Short Palindromic Repeats.
