As several people here have already pointed out, and as was mentioned in the article, the permafrost is already melting. This research is being conducted BECAUSE people are concerned about viruses thawing out and becoming infectious again. They're looking to see where the viruses are, what kinds we'd be dealing with, and whether they even would still be viable after so long (as this test determined, the answer is at least sometimes yes, which is good to know!). And the article also specifies it's a virus that only infects amoebas - they specifically chose it because they didn't want to risk reviving anything that could spread to people or animals.

Everyone's so eager to believe scientists don't know what they're doing, I stg. I blame Michael Crichton.

TO BE FAIR, internal decapitation is a slightly different thing than regular decapitation, and it is at least POSSIBLE to survive depending on how exactly it happens. Not that I believe it happened to this lady, but from what I can tell what she's actually claiming is that

A) she survived a severe but theoretically survivable injury as a child,

and

B) now she has visions that tell her things.

Which is still completely bonkers of course, but I do feel like it's a more common, down-to-earth type of crazy compared to "I received this email from the ghost of Anne Boleyn".

And honestly? I'm kind of disappointed. The 'headless time specter' angle is so much more fun. Another headline over-promising, what else is new...
