The sensors have many potential practical uses - in Government buildings, train carriages, cargo containers, on a soldier's lapel - and are a thousand times cheaper than current sensors that are used for the same purpose.

They also explained how the sensors can monitor the levels of acetone on people's breath, and this can be used to tell people who suffer from diabetes when their next insulin shot is due. This is a more discreet method than what is currently on the market.

Melbourne is wonderfully altered since I last saw it. There are some very fair buildings in it now, and things are a little cheaper than they used to be.

It's cheaper to buy a house and finance it than it is to rent in many markets.

It's doable but is it practical? That's another question, ... The biggest obstacle I see is clearing all the buildings from the infield. When I ran the track (1978-82) there weren't as many structures as there are now. It seems to me that it would be very costly to tear everything down, then build it back just to play one football game.

There have long been rumors surrounding Lloyds as a potential bid target. Wells Fargo has a large part of its business in the retail banking arena so to take over someone like Lloyds would make a lot of sense.
