Does anybody have a link to a good site which offers videos of the elements being used?
I have one: http://genchem.chem.wisc.edu/lab/PTL/PTL/Elements/H/H.html
Its pretty good - just select an element from the preiodic table and click the video tab.

Hi, I would like a specific topic related to Psychology, social sciences and Cognition. Cognitive Science is science, IMHO, and it is very difficult to find other topics that cover cognition. The only related topic is Neuroscience, but ofcourse cognition entails a lot more than just neuroscience. And I can imagine that not all neuroscientists would love it when their topic would be flooded with cognitive questions
Its a good point but how many cognition threads are actually posted? It would have too be quite a few if a new seaction is to be created for them

Thats insane. How do you contain 510 million degrees celsius!
Its only possible for a few seconds, in this time the radiation can't do much.
You can be assured that the chaimber in which they do these tests, it looks like a doughnut!, is well insulated to make sure no heat escapes

Considering viruses complete their life cycle by hijacking your own cellular machinery and using it for their own benefit, and considering the fact that if a cell recognizes it is infected with a virus it will sucide (assuming the infected cell isn't killed by your immune system first), and also considering that infected cells can have up to 1 million viral particles inside them, oh yeah and also considering the fact that for some virsues the only way they can get out of the cell after assmbly is by blowing it up, what exactly is a 'harmless' virus?
The article did say that a virus could hijack another virus - don't ask me how but I'm just quoting what was said - it did say instead of injecting RNA that makes it replicate new viruses, it just screws up the system totally.
A harmless virus is one that does no damage to the host cell, just because the ones that evolved do does not say anything about what a genetically modified one can do assuming we can get the technology to program them.
Alchemists were trying to find a magic formula that could turn any metal into gold, they fauled but they discovered many elemements in the attempts.
There can be no such thing as a perfect vaccum nor can a temperature reach or go below absolute zero.

well, seeing as how I don't read science magazine, I couldn't have known that they published an article on it, could I?
Good point..
So they're using viruses to fight the other cold viruses? That's what it sounds like you said.
Experimentaly they are thought he mutations of both the good and the bas strains are proving hard to keep tracks with and this they both end up becomming quite ineffective soon... thats one problem that needs to be ficed!

The cold virus is not a single virus, but there are many different forms that are constantly mutating. I wish we could fight it, but there is no simple way to combat this. What is this research you speak of? Please provide a source.
What do you mean what research? Science magazine covered it in last months issue :S Not only that its part of the Cancer fighting research and viral biochemical research too.
And I know its not a single virus but the way they said it was a virus can mutate to fight the mutating virus.

I think that's wrong. I've read somewhere that solid plutonium will actually float on liquid plutonium due to solid plutonium being less dense. Someone confirm this?
Afraid not, at room temperature Plutonium has a density of 19.816 g/cm3 and at its melting point its density is 16.63 g/cm3. Solid Plutonium is denser than liquid Plutonium.
Although I do not agree with the statement too, its one of only a few known that their solid states will float on the liquid form, there are otherss I just can't remember the names!

That's not a fact... that's wishful thinking.
Its a fact, its already being tested as such and is therefor a fact.
Another one seeing as I'm posting.
Helium is the only known element that does not form a solid state at standard pressure no matter what temperature you try due to its weak inter-molecular forces!

I think an Economics forum may be appropriate in the "Other Sciences" catagory. Does anyone agree/disagree?
How many people actually talk about econmics? There will have to be quite a few for the forums to be added.
I hear its quite a complex area, I'll be avoiding it should it get added!

The most powerful explosive explosive known is as a Tritruim fussion bomb and is one of the most descricuve devices created by man!
Onle 1 person has been the sole reseptant for 2 Noble prizes.
A form of thermite can be used to extract pure Uranium! It is sometimes called the Ames process.

Water is one of only a few substances that expand when they freeze.
Hydrogen is the most abundant eleemnt sin the universe, constituting almost 90% os all the atoms in the universe!
Helium in its liquid state has a feature called superfluidity, that means it experiences no friction and is able to climb out of containers! It does this untill it meets its own "level".
Neon and Helium are the only two elements with no compounds what so ever although ionic compounds such as [ce]HeD^{+}[/ce] and [ce](NeH)^{+}[/ce] have been formed!

Astatine is probably the rarest naturally occuring element with the whole Earth containing only about one ounce or 25g of this element!
Fluorine is the most electrogegative element known with an electronegativity of 4 and will forn compounds with just about every element including some of the noble gases!
Nitroglycerin (glyceryl trinitrate) is used to treat angina pains!

It depends on how people look at it. My perspective is rather different than you Ryan Jones' date=' because you are not thinking thoroughly. If we have the ability to cure gene even before birth, it can have its disadvantages. If everybody is born perfect then there will be too many people on the planet. We succinctly need thousands of people to be dead every day. I don't want to sound like a devil but it's a way to reduce our exponentially population boom. We are running out of resources and natural needies. UNLESS, we create morbid space station out in the space? Anyway right now it's not a good idea to converse sicken babies into perfects.
What do you guys think?[/quote']
Good point... I was only refering to genetic disseases you understand though - I don't theink there will ever be a 100% effective system against viruses, bacteria and the like for a very, very long time if ever so that will continue to keep the populations down. Nature has a way of doing that - like in places like Africa where they have droughts and desertification because there are too many people on the land, they over work the land, all the plants die. Next no rains come because the soil gets erroded and its nutrients leached. Next no nutrients no plants and so transpiration form plants - no rain (Or a hell of a lot less). Thus people die lowering the population too an acceptable level.
Only problem is now food aid is sent its keeping the populations up so the planet has no time to recover. I'm not here to discuss the moral issues here (Nor do I want to anyway) but either way the higher a population does the greater risk of something bad happening. Thats just the way things work in nature in the end no ammmount of food-aid will stop whats going to happen :S
Anyway yes I do agree with you - a world without dissease will lead to exactly the same problem as in places like Africa now so I agree with you 100% on that point. Nature has a way of adapting its self to stop us doing just that - you find a great drug and in a few years its useless...

Genetic Engineering is going off like a rocket. Who knows if humans would be smarter' date=' faster, stronger, or ? But it's good thing I won't live THAT long to find out. I'm satisfy where I am now.
[/quote']HeHeHe, super-humans!
It has one huge advantage though - the ability to fix genetic problem at or before birth and this could save a lot of lives. Maybe even help prevent cancer and help to cure it too.
Loads of uses for genetic engineering as long as those annoying "do-gooders" and "mooral idiots" keep their annoying protests away from it... They have a habbit of ruining the good ideas that can save lives like stem cell research another interesting field today and let us not forger about GM modified foold... could solve world hunger but no its immoral because we'r acting like god...
Ah well they can't protest forever
I wonder when the first GM human will be born - anyone care to bet on a date?

Hmmm, now that you mention it, I was wondering... How far away are we genically from non-ape mammals?
From what I hear we have about 52% of the same [acr=Deoxyribonucleic acid]DNA[/acr] that a bannana(sp?) has!
Thats pretty nuts when you think about it - hey mom, I'm half bannana!

I thought R stood for Random.
That would be a bit of a bad description I thibnk because amino acids and other organic cdompounds that involve an R group are not random they are infact highly organised and precise (Proteins coltroled through your [acr=Deoxyriboneucleic Acid]DNA[/acr]).
Cheers,
Ryan Jones

I don't think it does stand for radical. Side chains are not radicals!!
Here it is just the side chain of an amino acid (for example' date=' the side chain of Glycine is just H and for alanine it is CH3).
I always took R groups in organic chemistry to be an organic group (where R sort of stood for rest [of the molecule'])
Or it could mean Replace as in this R should be replaced by something. thats the way out Biol. teacher explained it anyway
