Researchers used cryptography to cloak irrelevant genetic information in individuals' genomes while revealing disease-associated mutations. They say the technique could vastly improve patient privacy.

Researchers have discovered how Cas1-Cas2, the proteins responsible for the ability of the CRISPR immune system in bacteria to adapt to new viral infections, identify the site in the genome where they insert viral DNA so they can recognize it later and mount an attack.
