Modern science engineered a breakthrough discovery when a group of scientist identified "corpuscles with the classic doughtnut shape of healthy blood cells" on Oetzi, the 5,300-year-old "Iceman" mummy of the Alps by using a so-called atomic force microscope.
In 2011, the Archeological Museum of Bolzano displayed Oetzi, the mummy of an iceman discovered on 1991 in the Italian Schnal Valley glacier. According to the story, Oetzi roamed the Italian Alps more than 5,200 years ago after being shot by an arrow in the back. The scientists said on Tuesday, that after using forensic technology to analyse which able to resolve images just a few nanometers (billionths of a metre) across his preserved blood.
To give chemical clues about a blood sample, the scientist led by Albert Zink used a Raman spectroscopy, in which refracted light from a laser beam able to analyze the sample. Their findings "showed the presence of haemoglobin and fibrin, which are key components in blood clotting, at the arrow wound on Oetzi's back," adds the AFP report. The Oetzi DNA analysis presented in February also revealed that Oetzi had brown eyes and hair and was allergic to milk products, to which lead us to believe that lactose intolerance is common long time ago. The findings also determined that Oetzi has lived in short time after his wound contrary to the ealier report that the Iceman died right after being shot. Oetzi was around the age of 45, and about 1.60 metres (five foot, three inches) tall and weighed 50 kilos (110 pounds). Thanks to modern technology today.
