Ancient Headless Remains Offer Clues To Dietary Structure Of Vikings
2013-12-06 09:43:14

Lawrence LeBlond for redOrbit.com - Your Universe Online It has long been known that ancient Vikings buried dead slaves with their masters, but new isotopic research of ancient skeletal remains is providing at least one researcher with more evidence of how these people lived their lives – more notably what their diets were like. Elise Naumann, a PhD candidate in archeology at the University of Oslo in Norway, has made several remarkable discoveries using the skeletons that were...

3 billion-year-old Rocks Contain Microfossils Of Plankton
2013-06-06 21:18:25

Penn State Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers. "It is surprising to have large, potentially complex fossils that far back," said Christopher H. House, professor of geosciences, Penn State, and lead author. However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also...

Ancient Predators Shared Their Food Supply

Brett Smith for redOrbit.com - Your Universe Online Your mother probably told you that it´s considered good manners to share your food, but according to new research; for large predators living 9 million years ago, sharing a food supply was a daily way of life. To better understand how these ancient predators divided up the available prey, a team of researchers led by US researchers and the Museo Nacional de Ciencias Naturales in Madrid used radioactive dating technology and a...

Bronze Age Trade Connections Revealed By Ancient Stinging Nettles
2012-09-28 14:22:15

A piece of nettle cloth retrieved from Denmark's richest known Bronze Age burial mound Lusehøj may actually derive from Austria, new findings suggest. The cloth thus tells a surprising story about long-distance Bronze Age trade connections around 800 BC. The findings have just been published in Nature's online journal Scientific Reports. 2,800 years ago, one of Denmark's richest and most powerful men died. His body was burned. And the bereaved wrapped his bones in a cloth...

Michael Harper for RedOrbit.com The age-old struggle between classes may be even older than we thought, according to a new study carried out by archaeologists from the Universities of Bristol, Cardiff and Oxford. According to their research, hereditary inequality may have begun as early as 7,000 years ago in the Neolithic era. The archeologists found evidence showing farmers who were buried with tools were also buried in better land than those farmers without. The research was...

NASA-funded research looks to isotope analysis rather than X-ray for measurement Are your bones getting stronger or weaker? Right now, it's hard to know. Scientists at Arizona State University and NASA are taking on this medical challenge by developing and applying a technique that originated in the Earth sciences. In a new study, this technique was more sensitive in detecting bone loss than the X-ray method used today, with less risk to patients. Eventually, it may find use in clinical...

Chemical tests on teeth from an ancient burial site containing the 3,550-year-old remains of a teenage boy wearing a unique necklace unearthed near Stonehenge indicate that the person buried there grew up around the Mediterranean Sea. The conclusions come from analysis of different forms of oxygen and strontium in the tooth enamel of the remains. A previous skeleton unearthed near Stonehenge was analyzed and was found to also be a migrant to the area. The "Boy with the Amber Necklace," as...
