Researchers discover a new kind of water ice
Researchers have discovered a new kind of water ice that appears to match the density and structure of liquid water.
he ice is called medium-density amorphous ice. The team that created it, led by Alexander Rosu-Finsen at University College London (UCL), shook regular ice in a small container with centimetre-wide stainless-steel balls at temperatures of –200 ˚C to produce the variant, which has never been seen before. The ice appeared as a white granular powder that stuck to the metal balls. The findings were published today in Science.
The abstract for the paper can be read here.
Not only does this discovery suggest that there are many possible states of water ice, with a range of properties, this new type of ice could help explain many of the features we see on planets like Mars that appear to have been caused by flowing water. Mars has a lot of glacial ice, much of which might not be ice as we assume.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Phase diagrams might tell us more. Solid, liquid, gas in this case. Something else awaits ?
Such as ‘cubic zircon’ did.
Just wondering.
I hope it’s not ICE-NINE
There actually is an ice-9—but it isn’t Kurt’s

Sodium Acetate is the closest I’ve seen in terms of a tiny bit solidifying its neighbor materials
Ice-7 is interesting

Dark Matter may be like ICE-9

I think there was a drug that could flip the handededness of a similar substance

Lots of links Jeff – thanks
This type of ice appears to be the reverse of the behavior we saw in liquid cloud water (i.e., fog).
Hall, Chris M., et al. “Anomalous noble gas solubility in liquid cloud water: Possible implications for noble gas temperatures and cloud physics.” Water Resources Research 57.12 (2021): e2020WR029306.
Fog seems to act as if it is liquid inside, but has a coating of an ice-like structure. This was found because of the strange differences in the solubilities of the different noble gases. We speculated that the “skin” of ice-like structure is formed because of the difference in density between the two states of water, combined with the large pressure gradient induced by surface tension. This might cause ice-like domains to “float” to the surface of fog particles.
