Using Supercomputers To Speed Up Genome Analysis
2014-02-20 11:11:12

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Bioinformatics say that genome analysis can be radically accelerated. Over the years, the cost of sequencing an entire human genome has dropped, but analyzing three billion base pairs of genetic information from a single genome can take months. A team from the University of Chicago is reporting that one of the world’s fastest supercomputers is able to analyze 240 full genomes in about two days....

New Interactive Map Reveals Human History Of Genetic Mixing
2014-02-14 06:41:32

Lawrence LeBlond for redOrbit.com - Your Universe Online A multi-institutional team of researchers this week published in the journal Science a study identifying, dating and characterizing the genetic mixing between populations around the world. Along with the study, the team released an interactive map detailing the histories of this genetic mixing. Researchers from Max Planck Institute for Evolutionary Anthropology, Oxford University and University College London developed...

Genome Analysis Reveals Origins Of Genetic Adaptations For High Altitude In Tibetans
2014-02-11 09:00:22

University of Chicago Medical Center Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study by scientists from the University of Chicago and Case Western Reserve University,...

Neanderthal Genome Survives In Modern Humans
2014-01-30 04:32:46

redOrbit Staff & Wire Reports - Your Universe Online More than 20 percent of the Neanderthal genome survives in modern human populations, and individuals currently living outside of Africa are composed of between one and four percent Neanderthal DNA, according to a pair of new research papers published on Wednesday. In the first study, population geneticists Benjamin Vernot and Joshua M. Akey of the University of Washington’s Department of Genome Sciences used a new approach to...

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),...

Neanderthals Buried Their Dead
2013-12-17 07:44:47

redOrbit Staff & Wire Reports - Your Universe Online A 50,000-year-old Neanderthal skeleton discovered in a cave in southwestern France was intentionally buried, a finding that confirms burials took place in Western Europe prior to the arrival of modern humans. “This discovery not only confirms the existence of Neanderthal burials in Western Europe, but also reveals a relatively sophisticated cognitive capacity to produce them,” said William Rendu, the study’s lead author and...

Identifying network of 39 biologically related genes may suggest new targets for treating or preventing alcoholism There is good evidence from studies of families and twins that genetics plays an important role in the development of alcoholism. However, hundreds of genes likely are involved in this complex disorder, with each variant contributing only a very small effect. Thus, identifying individual risk genes is difficult. Using a new approach that combines genome-wide association...

The unique genomic signature could serve as a research model for founding events Researchers at the Sainte-Justine University Hospital Center and University of Montreal have discovered that the genomic signature inherited by today's 6 million French Canadians from the first 8,500 French settlers who colonized New France some 400 years ago has gone through an unparalleled change in human history, in a remarkably short timescale. This unique signature could serve as an ideal model to study...

The Mystery Of Handedness
2013-10-02 05:23:47

April Flowers for redOrbit.com - Your Universe Online Most of us are right handed, with only approximately ten percent of the population of the UK, and the world at large, being left handed. But why that is so remains a mystery. Two independent studies might have given us some clues to the mystery, however. Professor John Armour and Dr. Angus Davison from The University of Nottingham collaborated with University College London's Professor Chris McManus to rule out a "strong genetic...

As gene sequencing technologies rapidly advance and new genomic data becomes available, so does the need for a better understanding and consensus on which gene changes are relevant to diagnosis and treatment. With a $8.4 million, four-year grant announced today from the National Human Genome Research Institute, researchers from Baylor College of Medicine and The Stanford University School of Medicine hope to address this need by creating a central resource. "The Stanford/Baylor effort...
