Zinc

Fresh off the press, breaking news today.... It is speculated that Zinc can be effectively used to treat the common cold. We all know Zinc as a 'pseudo' transition element (is it a transition element or not? Why?) But now, researchers are claiming that Zinc lozenges of Zinc syrup can be used to treat the common cold. 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 ...

Coal and Sand …. in Space?

I wouldn't think of myself as a BBC Radio 4 listener but while I was waiting for news of the first exit poll in UK's General Election last Thursday the following programme was playing: http://www.bbc.co.uk/programmes/b00s7b6r#supporting-content And it was really cool (excuse the pun :lol:) Astronomers know that there are vast areas of space that are 'starless' but over the last few years using a new IR satelite that they has found these empty areas of the sky are really cold and full ...

What happens when things get cold… really cold?

  The Boomerang Nebula (also called the Bow Tie Nebula) is a protoplanetary nebula located 5,000 light-years away from Earth in the Centaurus constellation. The nebula is measured at 1 K (−272.15 °C; −457.87 °F), the naturally coldest place known in the universe. The Boomerang Nebula was formed from the outflow of gas from a star at its core. The gas is moving outwards at a speed of about 164 km/s and expanding rapidly as it moves out into space. This expansion is the cause ...
