New Kind of Metal Theorized To Be In the Earth's Lower Mantle
slew writes "This article talks about a study accepted to Physical Review Letters which theorizes that iron oxide goes through an insulator/metal phase change with high temperature and pressure. Originally it was thought to be a crystalline structure change, but now apparently it is theorized to be a new type of metallic state. This discovery might offer new insight on how the earth's magnetic field operates."
dig a hole?
... is so metal!

...diamond pickaxe ready,
Glad you married a high maintenance gold digger.
My wife hates diamonds. And why would a woman want a common rock like a diamond on her?
They theorize that iron oxide becomes metallic at 1.4 million atmospheres (140 GPa) while also at ~2,200 deg C. If i'm not mistaken, is this P-T range way outside the capabilities of a diamond anvil press? Would this have to be an impact or laser shock experiment?
Gravity comes from a magnetic field, and that is produced because we have a big magnet like metal compound inside the earth, and I know that crystal is not able to become magnetized, so it all makes sense to me!
The Kola Superdeep Borehole is the deepest, reaching 12,262 metres (40,230 ft).

Its just a metal compound that conducts under these conditions. As they say, it doesn't even change its structure.
No, it's allotropic iron! We can power starshs and form the Lensmen!
I'm old. :-(
You are old. Do you think any "X" could be hanging around down there? As a physicist I have long wanted to experience an acceleration of c (the speed of light) driven by the awesome power of a disintegrating copper bar. Only I can't figure out how.

Well, that and that blue hottie, Neytiri.
This is a *press release* folks. It describes in detail what was and was not found and what part of that is new. The answer is NOT MUCH NEW HERE. What's unfortunate is that when the press picks something like this up, they strip off the "boring stuff" and make it into the breakthrough it's not. Read the release: The metalizaiton of iron oxide at high pressure was known. What is new is the its crystal structure does not change. That's why it's in Phys Rev B and not Nature.
Because they sparkle, something which most people consider pretty (hence the use of things that sparkle in lots of decorative items).
Lysergic acid diethylamide is probably the easiest way.

The scientists dug too greedily and too deep.
I have had enough new metal for a lifetime. I had finally recovered from the emergence of Limp Bizkit and Papa Roach. If they are looking for a name, they should consider Kornium.
That's all well and good, but how does this affect the timeline for getting unbreakable bones and claws installed?

...Transparent Aluminum. Mystery solved! Scotty: beam me up.
That's fine but the question wasn't about "your wife" it was about "a woman". Lots of people couldn't give a shit about environmental damage and human rights abuses and neither do lots of women.
Lots of people are shitty people.
Give me Classic Slashdot or give me death!
"The Core" is a recent, hour-long documentary that provides some illustrative background (and CG) for the iron crystal theory, and explains some of the major difficulties in drilling below the crust. It's an episode of Horizon , a long-running science documentary series. You can watch the entire episode in 720p on YouTube.
May I quote an ethnologist : "Through a talisman made of a strange metal given to him by a local chieftain, he unearths a strange cylinder made of the same unidentifiable metal full of hideous engravings and strange hieroglyphics."
Ah, so it divides out by the missing time dimension, does it? Or are you suggesting that I spread LSD onto a copper bar and... hmm, that might just work, might it not. At least if I was listening to Pink Floyd -- Set your Controls for the Heart of the Sun -- at the time.

You need to start with a copper bathtub. Did you do that? No, you bloody well didn't. Kids today. There are no shortcuts!
I've fallen off your lawn, and I can't get up.
How did this get modded up? didn't follow links eh!
6000 year creationist explaining magnetic fields of planets created as water and transformed into other matter,
and as for fluctuating fields, quoting from linked
The Earth's field could, for example, have decayed steadily from creation to the Flood, reversed rapidly many times during the upheavals of the Flood, and afterwards resumed its steady decay

Can't wait for my new rust based electronics. Of course the 3000f operating temperature and 690k ATM pressures might make them unsuitable for mobile electronics.

How can it be new if it's been in the earth all this time?
No, it's allotropic iron! We can power starshs and form the Lensmen!

It checks to nineteen decimals! Break out the Bergenholms and DeLameters.

Nothing to do with sparkle. That can be done much more cheaply. It's to flaunt wealth. Fundamentally, the woman wants to show off how many resources her man can devote to her purely for pleasure. If diamonds were either cheap or had a practical purpose, they wouldn't be a display of frivolous wealth, and would no longer be desirable.
Diamonds have enormous practical purpose. They're used as cutting tools.
Actually artificial diamonds are used almost exclusively for that.
And even though artificial diamonds are available now for a long time and are cheaper than natural, natural diamonds are still the only ones considered for any sort of premium jewelry.
No we're not, actually. He's always been a bit of an attention whore
Think of how stupid the average person is, and realize half of them are stupider than that.
