The HN guidelines ask submissions not to edit the title except for certain narrow exceptions.

The title was from the cnn.com article. I've changed to that now from https://www.thelancet.com/journals/lancet/article/PIIS0140-6... - usually the best choice for studies like this is to link to the best third-party article and link to the paper in the thread.
