Enlarge / The process of repairing the damage cause by CRISPR can cause complicated DNA rearrangements. The ability to edit genes has raised the prospect of treating genetic conditions and arming the body to better handle infectious diseases and cancers. But for that potential to be realized, we need to deal with a variety of…

While cancerous cells look a lot like normal human cells, they're still different enough that the immune system regularly attacks them. Obviously, this attack sometimes bogs down, allowing cancer to thrive and spread. Figuring out how to get the immune system back on…

picture alliance/Getty Images A number of years back, there was a great deal of excitement about using viruses to target cancer. A number of viruses explode the cells that they've infected in order to spread to new ones. Engineering those viruses so that they could only grow in cancer cells would seem to provide a…

Transplanted stem cells can be as lifesaving as donated organs, but the Food and Drug Administration in September warned consumers that some stem cell clinics only pretend to be in the business of miraculous recoveries. Now, Google is attempting to…
