| On the cover: Medicine is the practice of the diagnosis, treatment, and prevention of disease. With the advances in medical science, human beings are getting both longer life spans and higher quality of life. From herbs to molecular signatures, humankind is experiencing a transition from traditional medicine to personalized medicine: the right treatment to the right patient at the right time. However, it is not so easy to achieve this goal because the etiology of most diseases and disorders is still unclear. From description to association, numerous researchers are working together to decipher the mechanisms behind disease. To address such challenges, more and more global collaborations are badly needed to include experts from all disciplines: not just doctors, scientists and administration staff, but also engineers, technicians and marketing managers. Not limited to a fish-eye view, we humans should widen our vision and get more deep insights beyond the human community. That is the right way to assure sustainable healthcare for humanity. |

GRAPHICAL ABSTRACT
The naturally occurring prokaryotic CRISPR-Cas systems provide valuable resources for the development of new genome-editing tools. However, the majority of prokaryotic Cas nucleases exhibit poor editing efficiency in mammalian cells, which significantly limits their utility. Here, we have developed a method termed Improving Editing Activity by Synergistic Engineering (MIDAS). This method exerts a synergistic effect to improve mammalian genome-editing efficiency of a wide range of CRISPR-Cas systems by enhancing the interactions between Cas nuclease with the protospacer adjacent motif (PAM) and the single-stranded DNA (ssDNA) substrate in the catalytic pocket simultaneously.
