[QUOTE][B]Swedish and Spanish engineers have created a system of sensors that detects fruit odours more effectively than the human sense of smell. For now, the device can distinguish between the odorous compounds emitted by pears and apples.[/B]
Researchers from the Polytechnic University of Valencia (UPV, Spain) and the University of Gävle (Sweden) have created an electronic nose with 32 sensors that can identify the odours given off by chopped pears and apples.
"The fruit samples are placed in a pre-chamber into which an air flow is injected which reaches the tower with the sensors which are metal oxide semiconductors that detect odorous compounds such as methane or butane," explained José Pelegrí Sebastiá, UPV researcher at the Gandia campus and co-author of the paper.
Next, software is used to gather real time data and the information is processed through classification algorithms. The results can be viewed on a 3D graph which distinguishes between the pear and apple scores.[/QUOTE]

Pears are superior to apples
the following people prefer hard dry fruit over soft juicy fruit:

Wait, people cant tell the difference between the smell of pears and apples? I've always been able to tell the difference. Pears smell much sweeter for me.
sending farts online will become a reality
I wish I could smell anything. :(

Get your nose augmented.
I read it at first as "Electronic Arts", and thought it was gonna be a weird quote.
TBH human noses are quite shit anyway
But can it smell petril?

Yeah, but it gets it confused with cheese
