Why 118? Well... (Score 5, Informative)

A lot of people seem to be dismissing this as without a practical use. However there is method to the seemed madness of making ever-bigger nuclei. Elements tend to be either stable or unstable - carbon is stable, uranium is not. This stability is caused by the arangement of protons/neutrons in the atoms' nucleii. I'm not exactly sure why this occurs - I'm a biologist, I'm not really meant to know - but whether or not a nulceus is stable or not follows a pattern determined by "shell-model" calculations (see here for the science bit).

So although making 3 atoms of 118 doesn't seem to amount to much, especially as it instantly falls apart, it's another step on the way to making th first of the synthetic heavy elements in a "stability island". It's thought that such a material could have strange and useful properties. Or it could be a complete waste of money and be boring as hell. I don't know, but that's the point of research at the end of the day...
