If the ice forms under high pressure would the crystalline structure remain intact under normal pressure?

TFA says they transported it “in carry-on luggage” after forming it to a different lab where they blasted it with the laser.

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.

Just saying that solid electrolytes ("superionic conductors" is just a synonym) have been around for a long time: https://en.wikipedia.org/wiki/Fast_ion_conductor

There's the zirconia oxygen-sensitive electrode in your car's exhaust system, beta-alumina (used in various high-temperature batteries), the high-temperature modification of silver iodide, and others. Fascinating subject, some of these are almost as conductive as metals!

My mind went immediately to Kurt Vonnegut's Cat's Cradle as well.

Yeah, in the hopes of this not being a candidate 'Great Filter' event I hope the scientists are dipping each ice form into a small cup of water before continuing on to the next stage.

Earlier quoted context omitted.

I'd suggest going to Philly to taste the water ice, but from what I understand it was recently sacked.

I'm pretty sure Tom Brady was the one who got sacked, not Nick Foles.

I believe GP meant sacked by vandals.

The article is a little unclear, but I think they're saying that it was compressed between pieces of diamond, then transported still pressurized within the diamond cell.

" The superionic ice could help explain the lopsided, off-center magnetic fields of Uranus and Neptune, the solar system’s seventh and eighth planets that are known as ice giants and were visited briefly by NASA’s Voyager 2 spacecraft in the 1980s. Instead of Earth’s magnetic field generated at the core of the planet, the fields of those icy bodies may originate, in part, within shells of superionic ice inside their…

> cool!!

Was that a pun?

"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.
