KEKB, asymmetric electron-positron collider with a performance similar or better than Belle or BaBar, the B factory detectors, in a much more severe beam background
environment. CRISPR (Clustered Regularly Interspaced Short Palindromic
Repeats) technology is a gene-editing technology that can be used for the purpose of altering genetic expression.
It scans the genome for the right location and then uses the Cas9 protein as molecular scissors in targeted DNA
