The US military will try to 'liberate' it?
China has announced the successful launch of its SJ-10 probe, which ascended into the heavens atop a Long March 2-D rocket overnight and will one day return to Earth. China's always happy to talk up its retrievable space technology, as it's successfully recovered 25 missions in recent years. That capability means China is …
When a mixed size bunch of particles (call Corn Flakes) in the article are shaken the large ones move to the top and the small ones separate to the bottom, it is because of the size of the particle not gravity. The small one can more easily fit between the big ones and this provides for the separation effect.

"how do you decide (without gravity), which is "top" and "bottom"?"
Considering that the article states they want to compare with what happens to oil underground, I'm not sure what relevance microgravity has in relation to effects on pressurised oil in the first place. Underground oil is always subject to gravity unless it falls down a very deep hole.
Air gets compressed adiabatically, so it heats up. Then the fuel gets vaporised by injection, and it combusts on contact with the compressed, hot air.
Just compressing 0.0017 milliJub of oil in a vessel capable of withstanding 103.95 kiloNorris per nanoWales, so quite likely rather thick-walled, and without any additional oxygen present, will not cause anything combustion-like to happen.
... the total theoretical amount of carbon that the human race will be able to release into the atmosphere continues to go up... And all the evidence suggests we will release it.
The best place for this stuff is where it already is. When are we going to break the chain of incentives that stimulate its release? Never, I suspect.
Does anyone know anything about the actual design of this probe? The best I've been able to find is a couple of pictures, which show something that doesn't look like it's descended from anything the Soviet space program cooked up.
If the Nevada Desert was OK for NASA and Tenerife for James Bond, then Inner Mongolia should be fine for the Chinese.
Must say I am a bit worried about the potential fruity flying rat hybrids escaping from Mongolia with their ultra high pressure flame throwers though.
Cornflakes settle the way they do by turbulent particle sorting when the box is shaken, not by "gravity". Left alone the small cornflakes will stay put.
How does this "heavy on top" theory stack against petrologocal theories that account for magma flows using conventional views on comparative material densities?

Both shaking and gravity are necessary wrt separating the cornflakes. You could shake a box of cornflakes all you like in zero gravity and there will be no separation. Molecules are constantly being shaken at any temperature above 0 deg K. Perhaps look up "Brownian motion".
Of *course* gravity is required. It just *isn't* the fiucking mechanism that sorts cornflakes.
My *point* being that liquid oil's position in the vertical geo table *should* be governed by comparative density and do the exact opposite of what the article is claiming, or vulcanism theory is falsified.

"The “Soret” mission shares space with an experiment studying “early-stage development of mouse embryos in microgravity to shed light on human reproduction in space” ..."
If they want to shed light on human reproduction in space - tell them to call me, I've got plenty of ideas.
