    When shaken and chilled to minus 320 degrees Fahrenheit, ordinary frozen water "turns into something different," reports the New York Times, "a newly discovered form of ice made of a jumble of molecules with unique properties." The ice of our everyday lives consists of water molecules lined up in a hexagonal pattern, and those hexagonal lattices neatly stack on top of each other.... With permutations of temperature and pressure outside what generally occurs on Earth, water molecules can be pushed into other crystal structures. "This is completely unexpected and very surprising," said Christoph Salzmann, a chemistry professor at University College London in England and an author of a paper published on Thursday in the journal Science that described the ice.... The new discovery shows, once again, that water, a molecule without which life is not known to be able to exist, is still hiding scientific surprises yet to be
    revealed. This experiment employed relatively simple, inexpensive equipment to reveal a form of ice that could exist elsewhere in the solar system and throughout the universe. And according to LiveScience, the new form of ice has some unusual properties: Among them, Salzmann said, is that when the researchers
    compressed the medium-density ice and heated it to minus 185 F (minus 120 C), the ice recrystallized, releasing a large amount of heat. "With other forms of [amorphous] ice, if you compress them and you release the pressure, it's like nothing happened," Salzmann said. "But the MDA [medium-density amorphous ice] somehow has this ability to store the mechanical energy and release it through heating." Medium-density amorphous ice might occur naturally on the ice moons of
    gas giant planets, Salzmann said, where the gravitational forces of the enormous
    worlds compress and shear the moons' ice. If so, the mechanical energy stored in
    this form of ice could influence the tectonics on these Hoth-like moons.... Scientists still debate the nature of water at extremely low temperatures. Any debate now needs to take into account medium-density amorphous ice, Salzmann said. Thanks to long-time Slashdot reader fahrbot-bot for submitting the article.

    Best final exam in chemistry I ever heard about: After 4 years
    majoring in chemistry, the all-department exam had one question:

    Discuss water. You have four hours.

    Guess it's just gotten even more demaning.

    And, OTOH, is there's the question: Does this have any connection with
    Ice 9?

    Which one ?

    Ice IX is a form of solid water stable at temperatures below 140 K or
    -133.15 C and pressures between 200 and 400 MPa. It has a tetragonal
    crystal lattice and a density of 1.16 g/cm³, 26% higher than ordinary
    ice. It is formed by cooling ice III from 208 K to 165 K. https://en.wikipedia.org/wiki/Ice_IX



    What happens when you touch ice 9?

    Kurt Vonnegut's 1963 novel Cat's Cradle introduced the world to
    so-called "Ice Nine," a fictional form of water that freezes at room temperature. If it so much as touches a drop of regular water, that
    will freeze, too, and so on, spreading so rapidly that it freezes
    everything that comes into contact with it. https://arstechnica.com/science/2018/10/weird-water-phase-ice-vii-can-grow-as-fast-as-1000-miles-per-hour/

    Not that one.

    Yes, that one. This is the way the world ends, not with a bang but
    with a stupendous FOOOOOMMMMBmmmm.

    I once walked from warm kitchen into twenty below (F) woodshed past
    bottle of white wine that had been put out there to chill. Door
    slammed behind me. I picked up what I was fetching and turned around
    to see that the bottle of wine had ejoyed an instant phase change from
    clear liquid to ice, triggered by vibration from the door slam. No
    precise data on MPH.

    For extra credit: Is MAGA a granfalloon?

    The granfalloon technique is a method of persuasion in which
    individuals are encouraged to identify with a particular
    granfalloon or social group. The pressure to identify with a
    group is meant as a method of securing the individual's loyalty
    and commitment through adoption of the group's symbols, rituals,
    and beliefs.

    "After World War II, Kurt Vonnegut worked in the public relations
    department for General Electric research company. GE hired scientists
    and let them do pure research, and his job was to interview these
    scientists and find good stories about their research. Vonnegut felt
    that the older scientists were indifferent about the ways their
    discoveries might be used.

    When science fiction author H. G. Wells visited the labs in the 30s,
    the Nobel Prize-winning chemist Irving Langmuir suggested for him the
    idea of a story about a form of ice stable at room temperature. Wells
    never took it any further, but Vonnegut's older brother Bernard, who
    was Langmuir's junior colleague at GE, remembered and told him about
    it.

    After both the author and the scientist had died, Vonnegut thought to
    himself "Finders, keepers - the idea is mine".[7] Langmuir himself
    would become the model for Dr. Felix Hoenikker. Vonnegut said in an
    interview with The Nation that "Langmuir was absolutely indifferent to
    the uses that might be made of the truths he dug out of the rock and
    handed out to whoever was around, but any truth he found was beautiful
    in its own right, and he didn't give a damn who got it next."[8]

    Dr. Felix Hoenikker's fictional invention of ice-nine was similar in
    name only to the real substance ice IX, one of a number of variant
    structures for ice. Langmuir had worked on seeding ice crystals to
    diminish or increase rain or storms.[9][10][11]
