Found trapped in a diamond: a type of ice not known on Earth
- british_india 9y agoIce 9?
- eganist 9y agoSeeing "atoms" used in reference to water molecules has me feeling a particular way. Am I nitpicking too hard? -- edit: moccachino makes a good point below that I missed on my first two passes -- it's referring to the actual positioning of the atoms within water molecules, which makes sense now that I'm giving it another pass. This is evident in referring in one part to "oxygen atoms" specifically.
- moccachino 9y agoIt seems to me the usage is correct, they are referencing the atoms that make up the water molecules.
- eganist 9y agoIt took me your comment to realize it. Thanks for pointing it out: the point that wasn't effectively conveyed to me was that the actual relative positioning of oxygen atoms relative to each other seems to be shifting under pressure. This speaks well to DrNuke's point as well.
- DrNuke 9y agoCommunicating research to non-specialists in an effective manner is the highest regarded soft skill for STEM profiles doing r&d these days, so yes you are possibly nitpicking here.
- ianai 9y ago<snip> sorry I said anything
- carlmr 9y agoNobody says they pay well for it. It's still journalism.
- amelius 9y agoStart with blogging, and build a portfolio.
- haZard_OS 9y agoI believe the parent post is referring to actual scientists/researchers who ALSO communicate well...not people who are not in R&D but happen to communicate well.
- lamename 9y agoYou could always try working for https://www.khanacademy.org/ https://www.khanacademy.org/ or some similar organization
- lamename 9y agoRegardless of the parent comments meaning, there's value in communicating complex ideas simply. You didn't have to snip your comment. If you want a job related to that kind of work, broadly, I'd search around for any STEM journalism or education related. Also many public health/nonprofits might have a significant outreach arm if they're large. Or you could go the blogger/educational youtuber route. Less traditional but pros and cons. Disclaimer: no first hand experience here, just my observations of others. Good luck!
- borkt 9y agoAs moccachino said it is the correct usage. I went to school for materials science and had a particular interest in ice physics.
- stupidcar 9y agoLet's just be grateful it wasn't ice-IX they found.
- binarymax 9y agoYes! Getting close though. Only two stages left. For those who need context: https://www.goodreads.com/book/show/135479.Cat_s_Cradle https://www.goodreads.com/book/show/135479.Cat_s_Cradle

- emmelaich 9y agoInteresting! For others, this isn't the Vonnegut Ice nine.
- mcherm 9y agoSounds like they haven't actually broken open the diamond, so can we really be sure?
- kurthr 9y agoThey don't mention it in the article, but it's likely to be IR spectroscopy, since that can measure resonance of H2O molecular bonds, which would be specific to symmetries/energies in Ice-7 and very different from the known spectrum of diamond. edit to add: http://www1.lsbu.ac.uk/water/water_vibrational_spectrum.html http://www1.lsbu.ac.uk/water/water_vibrational_spectrum.html However, I suppose it could also be X-ray crystallography, which would measure the actual crystal structure. Probably other methods as well...
- creep 9y agoThey do mention it in the article >But while they were scanning the diamonds with high intensity X-rays, they saw something else: The first conclusive evidence of ice-VII on the planet. But probably they used other methods to confirm.
- lamename 9y agoThis is fascinating. I had no idea ice could take on so many crystalline forms depending on the variety of conditions. Apparently there are other shapes even beyond those mentioned in the article: http://www1.lsbu.ac.uk/water/ice_phases.html http://www1.lsbu.ac.uk/water/ice_phases.html
- fastball 9y agoIf you find this interesting, you might enjoy Kurt Vonnegut's "Cat's Cradle", which is based around a highly dangerous (and imaginary) form of ice, ice-nine. And even if you aren't super excited about ice-nine, it's still a highly enjoyable read.
- luhn 9y agoI do really like Cat's Cradle, but I don't think its a relevant recommendation. Ice-nine is only a plot device, the book isn't about ice at all.
- theoh 9y agoWell, ice-nine does have a relationship to water specifically. For whatever reason, TV Tropes doesn't currently consider it an instance of the Phlebotinum trope (any substance or phenomenon which is essentially an entirely unexplained but powerful plot device). Maybe that's an unintentional omission from the wiki, but it could be that the somewhat elaborated hard SF backstory of ice-nine means that it's not just considered "plot fuel". http://tvtropes.org/pmwiki/pmwiki.php/Literature/CatsCradle http://tvtropes.org/pmwiki/pmwiki.php/Literature/CatsCradle
- trophycase 9y agoMy first thought when reading the article title was ice-nine :)
- cachvico 9y ago..and listen, https://www.youtube.com/watch?v=eyVWQH7jIg8 https://www.youtube.com/watch?v=eyVWQH7jIg8
- peter303 9y agoSome outer solar system moons are mostly water ice. Theircores could be this phase of ice.
- nfarrell 9y agoIce Nine???
- VVyattPrentice 9y agoSo it goes.

- kaycebasques 9y agoThe bit about compressibility tickles my mind. Really cool that some compounds maintain their structure while collapsing the space between, while others change their structure entirely when subjected to pressure. Would make for a cool visualization. Are there theories about what structure ice-VIII, ice-IX, etc. would take?
- eesmith 9y agoFollowing the link that lamename gave about 90 minutes before your comment says that ice-VIII is tetragonal as is ice-IX. The list goes to ice-XVII. See also https://en.wikipedia.org/wiki/Ice#Phases https://en.wikipedia.org/wiki/Ice#Phases .
- Osmium 9y ago> The bit about compressibility tickles my mind. One of my favourites is 'electride' bonding, where you compress a crystal so much that the electrons get squeezed into the gaps (interstices) between atoms instead, essentially making the electrons themselves act as anions. This is really cool, and makes you wonder what other exotic high-pressure physics waits to be found. https://www.nature.com/articles/nchem.2254 https://www.nature.com/articles/nchem.2254
- ghaff 9y agoIce has at least 16 different phases: https://en.wikipedia.org/wiki/Ice https://en.wikipedia.org/wiki/Ice Ice XVII has been predicted: http://www.sci-news.com/othersciences/chemistry/ice-xvii-chemists-predict-existence-new-form-ice-03633.html http://www.sci-news.com/othersciences/chemistry/ice-xvii-che...
- chaoticmass 9y agoSo is it still 'frozen' (it is ice afterall) even above 0c?
- komali2 9y agoYes, it is! Water has a pretty interesting relationship with pressure (interesting to nerds like me anyway) : https://physics.stackexchange.com/questions/60170/freezing-point-of-water-with-respect-to-pressure https://physics.stackexchange.com/questions/60170/freezing-p...
- joering2 9y ago+1 I read an interesting article a while ago that i cannot find anymore, it was about dooms day from science point of view. The bottom line is in case of metheor falling down it is not the impact or cloud of dust up killing you, but simple change of pressure that will not only boil all oceans but also will boil blood and water in your body. As pressure goes down so falls the boiling point of liquid. Edit: typos
- ghaff 9y agoIce is really a fascinating material generally, even just “normal” ice. My thesis advisor has pretty much made a career out of studying it. I didn’t do my material science work on ice personally though; he also studied high temperature super alloys earlier in his career.
- maliker 9y agoDang, got here too late to make the Vonnegut joke. But still in time to share a link about strange forms of non-ice H2O: https://en.wikipedia.org/wiki/Polywater https://en.wikipedia.org/wiki/Polywater
- oldmancoyote 9y agoThis conflicts with what I think I know about the occurrence of diamonds. For the most part diamonds are formed just below the surface in melts rich in dissolved carbon dioxide. These materials rise through the crust through very narrow pipes and explode when the carbon dioxide comes out of solution at the surface. These explosions form the bell shaped bodies that are mined for diamonds. Because of the phase behavior of carbon dioxide rich melts, and because the diamond grade just below the bell is very low, diamonds seem to be formed in the high pressure streams of carbon dioxide released when the temperature declines and the confining pressure is released at the surface. Perhaps there are "seed" crystals formed much deeper and such a crystal formed the nucleus for this diamond. From this popular article it is not possible to determine at what depth the water crystal formed. Conceivably it could have formed in the stream of carbon dioxide at the surface.
- andmarios 9y agoI don't know what they do on their website but it is as heavy as they can come. Scrolling the article in Chrome, causes music (play music, playing in another tab) to skip!
- bananatron 9y agoWhat a trip that in the future the most coveted jewelry will probably be from materials found on other planets (assuming we haven't gotten over this jewelry thing).
- joering2 9y agoMandatory in case someone wonders about OP last part: https://priceonomics.com/post/45768546804/diamonds-are-bullshit https://priceonomics.com/post/45768546804/diamonds-are-bulls...
- jey 9y agoDiamonds are bullshit, but body adornment is a human universal that exists in all cultures. So the diamond bullshit is hijacking something very real and human.
- bananatron 9y agoYou're totally right, but there are also a lot of 'real' and 'human/animal' traditions that we've collectively decided aren't worth continuing. I'd argue this should be one of them, but I'm not bullish on my preference vs. diamond advertising budget and a culture of perpetual consumerism.
- Sonnol53 9y agoHow much is it worth?
- samstave 9y agoShow me your BTC wallet
- asafira 9y agoHey everyone --- I work with defects in diamond for my PhD! While they are completely different from the chunks of ice described here, let me know if there is something I can help with.
- pichaipedro 9y agotl;dr: "Diamonds can trap small bubbles of extremely dense pressurized water when they form. Then, as the diamond moves up through the mantle, the water inclusion is subjected to cooler temperatures while remaining under the same pressurized conditions. In that very specific case, ice-VII can occur."
- DoreenMichele 9y agoAnd people keep acting like there's nothing left to really discover on earth.
- userbinator 9y agoGiven how much pressure it's under, I wonder if it might cause the diamond to explode if subjected to additional stress.
- drumttocs8 9y agoThank god it isn't ice-nine!
- aaraun 9y agoBut it was “known on Earth”, and had been observed in the lab - it just hadn’t yet been observed in nature. A bit of a sensational title.
- mjcohen 9y agoObviously ice 9.
