Maybe it's just my tired old eyes, but the Herculaneum scrolls (both the fragment in the linked article and this one from your "Villa of the Papyri" link"...
...look much more like Greek script than Roman to me...
What am I missing here...?

We're not missing it, the Faux News reporter missed it. He or she will be well suited for a career in journalism, probably be assigned to impeachment duty, er, that is, the DC beat. I think there may have been a press release from the team working on the non-invasive reading project, some kind of an update, perhaps?
The real blithering idiocy of the article -- I think it was pointed out earlier in the topic, but just in case... -- is that the scrolls were buried by the 79 AD eruption of Vesuvius, while Julius Caesar was assassinated by lawless cowards in 44 BC, an interval of 123 years.
