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.

Existing HIV medicines can stop the virus from replicating but not eliminate it.
