And the problem? Well, there are some side effects (nausea, vomiting) and it cannot be used long term (Zinc poisoning) and nobody is quite sure what makes an ...

Cold Isotope Chemistry

Isotopes react in the same way, don't they? Chemical reactions are unaffected by the isotopic composition so the percentage of different isotopes of the same element in a substance would be the same as the percentage of each naturally occurring isotope. Well, this is true on earth but it is not the case in space, deep space where the temperature is really low and the concentration of atoms very very small. In effect, one isotope will become more reactive than the other. Scientists have ...

Toxic Sludge

  What have Iron Oxide, Aluminium Oxide, Silicon Dioxide, Titanium Dioxide and Sodium Oxide all got in common? Well, they were the substances found in the highest concentrations in the recent toxic sludge spill in Hungary. What effect will they have? It seems open to debate at ther moment but you can read more here: http://www.bbc.co.uk/news/world-europe-11492387
