Scientists say they have successfully eliminated HIV from infected cells, using Nobel Prize-winning Crispr gene-editing technology. Working like scissors, but at the molecular level, it cuts DNA so "bad" bits can be removed or inactivated. The hope is to ultimately be able to rid the body entirely of the virus, although much more work is needed to check it would be safe and effective. Existing HIV medicines can stop the virus from replicating but not eliminate it.
