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.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.
Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

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

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.
“It’s ice, Jim, but not as we know it.”
