Thoughts to Ponder:
If Everyone Is Special, No One Is Special
|Lead in teeth holds secrets of person's origins, research shows|

By Barbara Liston ORLANDO Fla. (Reuters) - The lead in human teeth holds clues about where a person grew up and can help criminal investigators and archaeologists working with old or decomposed corpses, according to a University of Florida researcher. Because lead ore deposits around the world differ, and as young people's teeth absorb traces of the metal in the environment, the region where a person grew up can be distinguished through lead analysis of a tooth, said geologist George Kamenov. "If you were born in Europe and then came to the U.S., yes, IÃ‚Â will be able toÃ‚Â see that," Kamenov said. In addition to aiding authorities in identifying bodies, the analysis can help archaeologists locate human remains on an historical timeline, he said.

|Otzi 'The Iceman' Had Heart Disease Genes|
|07/30/2014 04:40 PM|
ÃƒÂ–tzi the Iceman, a well-preserved mummy discovered in the Alps, may have had a genetic predisposition to heart disease, new research suggests. The new finding may explain why the man Ã¢Â€Â” who lived 5,300 years ago, stayed active and certainly didn't smoke or wolf down processed food in front of the TV Ã¢Â€Â” nevertheless had hardened arteries when he was felled by an arrow and bled to death on an alpine glacier. "We were very surprised that he had a very strong disposition for cardiovascular disease," said study co-author Albert Zink, a paleopathologist at the Institute for Mummies and the Iceman at the European Academy of Bozen/Bolzano in Italy. Past research has revealed that ÃƒÂ–tzi likely suffered from joint pain, Lyme disease and tooth decay, and computed tomography (CT) scanning revealed calcium buildups, a sign of atherosclerosis, in his arteries.
|Octopus mom protects her eggs for an astonishing 4-1/2 years|
|07/30/2014 04:27 PM|
By Will Dunham WASHINGTON (Reuters) - If someone were to create an award for "mother of the year" in the animal kingdom, a remarkably dedicated eight-limbed mom from the dark and frigid depths of the Pacific Ocean might be a strong contender. Scientists on Wednesday described how the female of an octopus species that dwells almost a mile below the sea surface spends about 4-1/2 years brooding her eggs, protecting them vigilantly until they hatch while forgoing any food for herself. It is the longest known egg-brooding period for any animal, they wrote in the scientific journal PLOS ONE. ...
