Identifying People By Odor As Effective As Fingerprinting
A study has found that everybody has a unique body odor, like their fingerprints, that could be used as an unique identifier. The study showed that a persons unique odor stayed the same even if they varied their diet with strong smelling foods such as garlic and spices. "These findings indicate that biologically-based odorprints, like fingerprints, could be a reliable way to identify individuals," said Monell chemist Jae Kwak. I would have thought that hundreds of years of dogs tracking people would have proved this, but it's nice to know that science has figured it out officially now.
Why is this even Idle? This is actually somewhat interesting.... I hate Idle, Btw.

i need to know
each persons' fart has its own unique flavor too. although I don't envy the poor bastard who has to test this theory.
It's on Idle because this idea was invented by Shampoo.
the idea that fingerprints are unique is stupid, especially for anyone who is actually in law enforcement or forensics. you need 12 count it TWELVE different points of matching to even get a fingerprint submitted for evidence. so if this odor is just as effective that means its pretty much a scare tactic as much as "we got your fingerprints at the scene!" is
You people. First you complain that Idle isn't any good, and now you're complaining that it shouldn't be any good?
The details are trivial and useless; The reasons, as always, purely human ones.

First of all, tracking is not identifying. Second of all, if two people have the same scent but non-overlapping movement paths, you can successfully track the one whose path you're on, so ability to track is not a very pure way of measuring smell-based distinguishability. Thirdly, dogs probably have vastly different ability levels for tracking by smell vs. tracking by fingerprint due to the two leaving different amounts of trail material. Fourthly throughout these years, have comparisons been made between smell-dogs and print-dogs? And fifthly, just because the market uses dogs to track on smell doesn't mean it's the best way to even track people: there may be market inertia factors and/or cost/benefit ratios that favor using smelling dogs.

Science has not figured out that hunting by smell works. They've found out that odors are better than fingerprints for identifying people. If it had gone the other way, should we all go and replace our dogs? No, they probably work best in practice, due to better hardware support for the odor-based tracking.

No, I'm complaining that there is already a section for this article, it's called "Science", and that i feel people are artificially putting this in the wrong category to make it seem more legitimate.
The idea behind the idle section is to have articles that are sort of pointless - that's just the point, i'm not ragging on it. Thing is, i don't like that idea, i think it's stupid.

In Berlin, Germany during the cold war era, the Stasi (Big Brother Police) knew this! They could track individuals with smell. In fact they have a room FILLED with little jars of every citizens' personal smell! I've been there and seen the rooms. They had special dogs trained for this too. They would open the jar and let the dog smell some... then go out into the city and find this person, they had a good success rate too which is kind of surprising. They would even track people by spraying different pheromones on their target.
While this article may be misplaced, I'd say that while regular /. stories are "News for Nerds, Stuff that Matters," Idle /. could be considered "News for Nerds, Stuff that Doesn't Matter," but that you still might find interesting.
