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."
Hmm, the jewelry market is all atwitter. Diamonds formed under high pressure mounted on a ring formed under high pressure. I'm sure the ol' lady will put ME under pressure to get her one.

dig a hole?
... is so metal!

Sounds like someone has been cheesing again. Poor cats.
Seven puppies were harmed during the making of this post.
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!
Wonder if this will have any impact on microchip manufacturing?
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.
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.
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?

Fitting, no?
"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.
What kind of metal are we talking about? Thrash, Doom, Nu or Heavy?
oh well, I bet SLAYER is the only living thing that can play at earth's lower mantle anyway - answered my own question!
It's too bad that nobody has proposed a theory that could be measured for each planet in our solar system and tested against a prior prediction to see if it is accurate. That would be the perfect scientific solution to the problem of planetary magnetic fields.
Or maybe someone has (article from before Voyager launched, summary from after it passed Neptune): Article Summary
One commentator says, "you would have thought we would have given up guessing about planetary magnetic fields after being wrong at nearly every planet in the solar system. . . ."
Peter predicted that you would "deliberately forget" creation 2000 years ago...
Why are we running experiments in these expensive labs when we could just pray to Lemmy and beseech him to go get some for us?
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."
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?
Mantle Metal !!!!
That's why my wife likes cubic zirconia. It's reasonable, it's not destructive (to my knowledge) , there are no human rights issues and best of all, it has a higher refractive index than diamond. .. It's more sparklier!
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.
