Are there any among you who rarely barber? Although there are, certainly not like that done by scientists on this one. His name is Professor Stewart Walker, He a scientist from Adelaide who makes her own hair as the object of the research. And for the purposes of scientific research is never cut his hair for a decade. Wow, how long huh?
Associate Professor Stewart Walker from Flinders University has finally cut the hair which was maintained for 10 years. But this is not a ritual haircut at the barber hair. Because scientists from Adelaide is deliberately maintain her gray hair over the last decade as part of the preparation for scientific experiments.
Haircut on the head it will be analyzed the content of the details of elements and isotopes in it. In addition, Professor Walker also hope haircut will be able to reveal the details of the trip that has been done over the last 10 years.
In short, Professor Walker explains the haircut will be analyzed about how water molecules from different parts of the world different from each other. Unlike the things that can be revealed by DNA testing, this technique can reveal the story according to which a person is coming from.
"Water in the tropics may be different from the waters in the Arctic, so that when the drinking water - for example, I have been in Tromso in northern Arctic - I drink very different isotope and element content of the water I drank in Adelaide," he said.
"And when the water was trapped The hair trace me, then I will be able to find traces of water in Adelaide and also Tromso and trace water content of Scotland, a place which I will also visit in the future."
Professor Walker documenting his travels over the past decade for this experiment.
According to this technique could be useful in addressing a number of serious problems, such as the issue of asylum seekers, this technique can trace the route that has been taken by people smugglers.
In addition, post-disaster, this technique can be a useful tool in helping to identify victims.
"My colleague who was involved in addressing the 2004 Tsunami tell them difficult to identify the country of origin of the bodies they found. So for example, if it is known that the bodies of Thailand, then they will be able to send the victim to Pastor Thailand to be more appropriate memorial , "he said.
"We can also say" The victims came from Sweden and we must return to Sweden, "
This technique can also be applied to trace the origin of the food and beverage industry.
Professor Walker previously broke claims mention that wine sold in Hong Kong comes from the Coonawarra region of South Australia. It does look suspicious Wine seen from the bottle, cork and spelling errors on the label.
"Wine that can be claimed from Australia who have been sent out and then packaged in a bottle of local, so we have to analyze the isotopic ratios in wine it to prove that the wine may not be imported from Australia," he said.
The scientific examination confirms that not a drop of wine that were originally from Coonawarra.
