I have a new link to add: http://chemlab.pc.maricopa.edu/periodic/styles.html Lots of table formats Cheers, Ryan Jones

When most substances dissolve they produce an exothermic reaction, Ammonium Nitrate is one of the exceptions and whn added too water cna even cause the solution to freeze! Cheers, Ryan Jones

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. Cheers, Ryan Jones

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 Cheers, Ryan Jones

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 Cheers, Ryan Jones

Yes it is Cheers, Ryan Jones

Every cell in your body has about 1 meter of DNA (minus red blood cells), if you add all that up for one person you get a lot od DNA Cheers, Ryan Jones

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. Cheers, Ryan Jones

Good point.. 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! Cheers, Ryan Jones

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. Cheers, Ryan Jones

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! Cheers, Ryan Jones

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! Cheers, Ryan Jones

Tin has the most stable isotopes of any element (10 of them). Cesium Hydroxide has the highest pH possible, 15, and can dissolve glass. Glass is not actually solid but is a Thixotropic Liquid. Viruses may some day be used to fight colds via genetic engineering. Cheers, Ryan Jones

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! Cheers, Ryan Jones

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. Cheers, Ryan Jones

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! Cheers, Ryan Jones

I thought it was man-made? Oh well Water is unusual in that its boilling and melting points are much higher than other simmilar Hydrogen based compounds. Cheers, Ryan Jones

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! Cheers, Ryan Jones

There are more stars in the sky than there are grains of sand on all of the Earth Hydrofluric acid is a weak acid by class but it is far more corrosive than hydrochloric acid! Cheers, Ryan Jones

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! Cheers, Ryan Jones

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

Or it could mean Replace as in this R should be replaced by something. thats the way out Biol. teacher explained it anyway Cheers, Ryan Jones

And I would alo like to add that there are a hell of a lot of them, here are a few links that may be of interest to you http://sosnick.uchicago.edu/amino_acids.html http://en.wikipedia.org/wiki/Amino_acids Cheers, Ryan Jones
