Interesting snippet for the day:
Gold is a very useful metal but up until recently has not been noted for its magnetic properties, largely due to the fact that it is not magnetic. However scientist have now fixed this oversight, and have created magnetic gold through careful processing and nano-structuring. This has the potential to lead to many interesting developments in the electronics, and particularly the biomedical industries, where its chemical inertness is a major advantage. Having the ability to track and manipulate the gold magnetically may then allow significant improvements to current techniques.
Here is a good article on it (From Science Daily)
Here is the paper on it (Well, the abstract at least.)
