My mind went immediately to Kurt Vonnegut's Cat's Cradle as well.
Mine too.
It's not just the subject, but how the headline is presented, presumably quoting one of the involved researchers, ostensibly an expert on the subject:
"really strange"
That's both terrifying and comedic, a Vonnegut hallmark, really putting the "scare" into "scare quote".

#23If the ice forms under high pressure would the crystalline structure remain intact under normal pressure?
I too always assumed that once pressure was released that other forms of ice revert to more mundane forms. This changes my thinking quite a bit.
Any phase change and polymorphism costs energy if the energy required to disorganize the crystalline structure is high it should be able to be maintained under pressures it can’t form under.
Diamonds don’t break apart just because their structure requires high pressure to form.
As long as the melting point of the ice at 1 atm pressure I don’t see why it would break down but material science isn’t my forte hence the question.

Ice IX actually exists [1]. Somewhat more boring than Vonnegut's ice-nine though.

#25"Newly discovered"? This is from the Nature Physics page for the original article [1]: Received: 27 October 2015 Accepted: 01 November 2017 Published online: 05 February 2018 That has got to be the longest stretch between submission and acceptance I've ever seen for a single paper. I wonder how many rounds of review that took. [1]: https://www.nature.com/articles/s41567-017-0017-4

#26Incorrect science in explanation of "normal" ice:
>Water is a simple molecule — two hydrogens attached to one oxygen. The three atoms normally form a V-shape. In the usual ice found on Earth, the Vs connect in an airy structure. (That is why water, unlike most every other substance, expands when it freezes.)
Not quite, the "airy structure" (overlooking the fact that there is no air between the molecules) is caused by hydrogen bonding, not the V shape.
