This video was published in 2016-10, and contains this exquisite quote (around 6'):
> In 2015, scientists use CRISPR to cut the HIV virus out of living cells from patients in the lab, proving it was possible. Only a year later they carried out a larger scale project with rats that had the HIV virus <sic> in basically all of their body cells. By simply injecting CRISPR into the rats tails they were able to remove more than 50% of the virus from cells all over the body. In a few decades, a CRISPR therapy might cure HIV and other retroviruses ...
I'll add a nod to the Kurzgesagt CRISPR video recommendation. It is really nice introduction to the discovery of CAS9, CRISPR as a DNA editing technique, and the fast evolving possibilities of CRISPR.
