KentuckyFC writes "The first naturally occurring superheavy element has been found. An international team of scientists found several nuclei of unbibium in a sample of the naturally occurring heavy metal thorium. Unbibium has an atomic number of 122 and an atomic weight of 292. In general, very heavy elements tend to be unstable but scientists have long predicted that even heavier nuclei would be stable. The group that found unbibium in thorium say it has a half life in excess of 100 million years and an abundance of about 10^(-12) relative to thorium, which itself is about as abundant as lead." I'd also like it known that my spell checker did not know 'unbibium' before today, but it is now one word closer to encompassing all human knowledge.

These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons. Since Governmentium has no electrons, it is inert; however, it can be detected, because it impedes every reaction with which it comes into contact. A tiny amount of Governmentium can cause a reaction normally taking less than a second, to take from four days to four years to complete.
Governmentium has a normal half-life of 2-6 years. It does not decay, but undergoes a reorganization in which a portion of the assistant neutrons and deputy neutrons exchange places. In fact, Governmentium's mass will actually increase over time, since each reorganization will cause more morons to become neutrons, forming isodopes, not to mention multiple oxymorons.
This characteristic of moron promotion leads some scientists to believe that Governmentium is formed whenever morons reach a critical concentration. That hypothetical quantity might normally be called 'critical mass' but, in this unique case it is known as 'critical mess'.
When catalyzed with money, Governmentium becomes Administratium (Am), another just-discovered element that radiates just as much energy as Governmentium since it has half as many peons but twice as many morons.

Over time, Capitalium produces emissions of money, some of which is absorbed by nearby Governmentium. Capitaliums will thus try to move as far away from Governmentium as possible. But most of this money is transmitted between other Capitaliums in what is know as the venture band. These oscillations of money produces economyetic radiation, which attracts more entreprenions, and stimulates peons, but also attracts greedions and slackhyons which have the temporary effect of increasing the flow of money in the venture band, while increasing their own energy.
However, as the flow in the venture band increases, the greedions and slachyons reach critical mass, and the flow of money becomes unstable and suddenly reduces dramatically. Capitaliums spontaneously split from their now depleted opportunium and evolve into Spend 0 particles, refusing to bond to any more opportunium. Any peons in the region become inert and may decay, or be absorbed by greedions and slackhyons, forming anti-entreprenions, which have the effect of destroying any opportunium they contact with.
The state will remain unstable for a time until the depleted Capitaliums begin to move closer to Governmentium. When this happens Governmentium undergoes a shift and emits bailout radiation, which has the effect of releasing vast amounts of stored money into the venture band and into Capitaliums. This restimulates the Capitaliums and they once again begin to emit economyetic radiation, and also move away from Governmentium.
Interestingly, Governmentium can be formed by either the fusion of peons, or the fusion of Capitaliums. However these two types of Governmentium have different spins, which manifests itself through their interactions with Medium, a type of Capitalium, which has the ability to pick up Governmentium and Capitalium spin, and then broadcast it to nearby peons.

Firstly thorium itself is not fissile, but Uranium-233 which can be created from it is. Using thorium for nuclear fuel therefore requires a breeder reactor and associated reprocessing. At the moment this is more expensive than using enriched uranium in light water reactors, but it may change if the costs of reprocessing decrease.
The second problem is the reprocessing itself. The Uranium made from thorium will contain traces of highly radioactive gamma emitters, and current reprocessing techniques are unable to adequately shield the workers from this radiation. There is also very little experience with thorium based reprocessing.
When it comes from nuclear proliferation thorium reactors would need safeguarding just as a conventional reactor would. The main reason is that while thorium itself is not usable in nuclear weapons, the Uranium-233 which is breed from it would be quite suitable. If that were to prove unfeasible it would also be possible to use a highly-enriched U-233 core surrounded by a U-238 breeder blanket to produce Pu-239, used in plutonium based weapons.
Basically if you are going to run a nuclear reactor you will need safeguards to prevent proliferation. This need not be a reason why we can't use nuclear power, it just means we shouldn't give the technology to every dictatorship on the planet that is willing to sign a piece of paper.

Thorium isn't fissile, so it's not just a matter of swapping U for Th.
Current fission reactors are based on same chain reaction that makes nuclear weapons work. Some people want to breed Th into U to keep using these reactor designs, but the cool thing about Th is that you can use it in a subcritical accelerator-driven system [wikipedia.org]. This is a truly safe form of nuclear reactor - pull the plug and the reaction stops, no way that it can melt down. It can actually "burn off" nuclear waste. And because no plutonium is created and the mix of uranium isotopes it produces is hard to weaponize, it's proliferation resistant and not a terrorist target the way a conventional plant is. Thorium is much more abundant than uranium, and easier to mine and process.
If fission has a future, it's accelerator-driven systems. We ought to be putting our reasources toward funding the R&D needed to deploy them instead of building dirty and dangerous uranium or plutonium fission plants.

After reading their paper, it's clear they haven't proven their case. There are *so* many possible explanations for the handful of counts they observed that this result should be ignored. Let me give a few:
- Molecular ions. They say there are no known molecular ions at this mass, I say BS. There are lots of observed molecular ions out there whose exact atomic makeup we haven't figured out. The worst is the interference on 87Sr that screws up lots of icpms age dating work and is not 87Kr (or we could correct for it). But there are others.
- Hydrocarbons: They say there are no hydrocarbons in the blank -- have they ever thought of hydrocarbons that are only ionized when lots of other things (ie a sample) is being ionized? No. They exist though, and are difficult to rule out. They didn't try very hard on this one. Try aspirating a solution of something else (U maybe, or Pb) and see what they get on 292. I'll bet there are counts, and they're not superheavies.
Another reason to be skeptical is that their Th solution is chemically purified. How are they going to do that without getting rid of the superheavy, which is after all not Th, and will be removed by any chemical process.
This is highly dubious work.

It's important, but I'd hardly call it one of the greatest discoveries made. It just confirms what we've suspected all along--There are stable elements past Uranium. There's a very narrow set of conditions that can synthesize them, and we haven't had alot of luck in the labs, but now that we know nature's managed it, we can possibly devise new experiments better aimed at sucessfuly generating these heavier elements.
As far as how it got there naturally--presumably the same way all the naturally occuring heavy elements came to be--Supernovae billions of years ago.
