The current title in HN is "Yellowstone Supervolcanoe begins de-gassing rare Helium 4 isotope". Helium 4 is the most comon Helium isotope, the article says that the degasing started 2 millon years ago ("recentlty" in geological time). The URL is ...\la-sci-sn-yellowstone-helium-degassing-... , so this was probably the original title.
The current title of the article is "It's up, up and away for ancient trapped helium at Yellowstone". It's a little confusing and a little uninformative, but at least it's not wrong.
