A team of Researchers at Rockefeller University and found that bacteria could form genetic memories of viruses they’ve run across. But they don’t do it very often.Researchers discovered a way to improve the bacterial immune system’s memory. CRISPR, generally known as a gene editing tool, found within many bacteria. Researchers at the University of California, Berkeley also accompanied them in this discovery.
CRISPR evolved in bacteria as an immune system to protect them from viral infections, but scientist now using it for their own benefits. Cas9 (CRISPR associated protein 9) is used to snip out a piece of DNA, which may be used to design DNA-based storage methods in the future.
This discovery published in Molecular cell on 22 December. According to the discovery, a bacterium will remember a virus by keeping snippets of the viral DNA. This helps Cas9 to locate the virus quickly if it shows up next time and destroy it instantly.

Moreover, This discovery proves useful and could bring scientists one step closer to developing DNA- based data storage devices.
