redOrbit Staff & Wire Reports - Your Universe Online By sequencing the mitochondrial DNA of the first Near Eastern farmers for the first time, an international team of researchers have discovered evidence supporting an Early Neolithic pioneer maritime colonization of mainland Europe that involved expansion through Cyprus and the Aegean Islands. Writing in the journal PLOS Genetics, the study authors explained their analysis of genetic samples obtained from three sites located in...

Polynesian Chickens May Have Flown The Coop, But They Didn't Make It To South America: Study
2014-03-19 11:07:14

Lawrence LeBlond for redOrbit.com - Your Universe Online It is commonly agreed in the scientific community that Polynesians expanded their culture throughout the South Pacific some 3,000 years ago and later arrived in places like Tahiti and Hawaii. But did the Polynesians make it all the way to South America? And if they did, did they beat Columbus? New evidence paints a pretty clear picture that Polynesians were in fact not the first to arrive in South America, and maybe never made the...

New Method Allows Researchers To Sort Out DNA Contamination
2014-01-28 06:53:19

April Flowers for redOrbit.com - Your Universe Online Special precautions are usually a part of retrieving ancient DNA to prevent DNA from researchers or the environment from mixing with that of the fossil. Many ancient fossils, however, have been lying forgotten in museum collections for decades that have become contaminated with present-day human DNA before even entering the laboratory. A solution for this problem, published in Proceedings of the National Academy of Sciences (PNAS),...

Scientists Unlock Evolution Of Cholera And Identify The Strain Responsible For Early Pandemics
2014-01-09 12:57:03

McMaster University Working with a nearly 200-year-old sample of preserved intestine, researchers at McMaster University and the University of Sydney have traced the bacterium behind a global cholera pandemic that killed millions – a version of the same bug that continues to strike vulnerable populations in the world's poorest regions. Using sophisticated techniques, the team has mapped the entire genome of the elusive 19th century bacterium. The findings are significant because,...

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...

Next Generation Sequencing Reveals Absence Of DNA In Sub-fossilized Insects
2013-09-12 10:48:12

University of Manchester Research just published in the journal PLOS ONE by a team of researchers from the Faculty of Life Sciences at The University of Manchester can now confirm that the existence of DNA in amber fossils is highly unlikely It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the fascination of the public for two decades....

Genetic Evidence How Man Migrated To Europe
2013-08-12 14:47:31

Brett Smith for redOrbit.com - Your Universe Online Humans emerged en masse from Africa thousands of years ago, but scientists still aren’t sure about the exact routes they took as they set out to populate the planet. According to a new DNA analysis from an international team of researchers, human expansion most likely occurred after the Last Glacial Maximum, between 26,500 and 19,000 years ago, and the Neolithic Era, approximately 12,000 years ago. The researchers reached their...
