The Genographic Project by National Geographic - Human Migration, Population Genetics

The Genographic Project by National Geographic - Human Migration, Population Genetics
Since its launch in 2005, National Geographic’s Genographic Project has used advanced DNA analysis and worked with indigenous communities to help answer fundamental questions about where humans originated and how we came to populate the Earth. Now, cutting-edge technology is enabling us to shine a powerful new light on our collective past. By participating in the latest phase of this real-time scientific project, you can learn more about yourself than you ever thought possible. You will also help support the Genographic Legacy Fund, which works to conserve and revitalize indigenous cultures around the world. Loaded: 0% Progress: 0%

How to make your own calculator for DIYDodecad As I have explained in the README file of DIYDodecad, it is possible to use the software to create and distribute new calculators, based on different marker sets/ancestral populations. (The following discussion will only be useful to other genome bloggers, or people who have experience with ADMIXTURE software). Currently, DIYDodecad is distributed together with the 'dv3' calculator ("Dodecad v3"). This consists of a set of files: dv3.par (The parameter file that tells DIYDodecad what to expect and what to do) dv3.alleles (Allele names and variants) World's oldest known fossils found in Greenland push evidence for life back by 220 million years - Science News Updated The oldest fossils known to date have been discovered in 3.7 billion-year-old rocks in Greenland by an Australian-led team of researchers. Key points Evidence of ancient bacterial communities known as stromatolites uncovered in rocks in GreenlandDating of rock above and below stromatolites places them between 3.7 and 3.68 billion years oldAnalysis pushes back earliest known evidence of life on Earth by 220 million years

Decoded: The Mystery of Human Migration - Science - News Click here to see the graphic 'The maternal journey of OF mitochondrial DNA' Half a million people from around the globe are participating in an ambitious project to reconstruct some of the ancient migratory routes that took Homo sapiens from their ancient African homelands to the relatively new territories of Asia, Europe, Oceania and America. Hidden within the genetic makeup of people alive today is the encoded story of how their ancient ancestors made this epic journey, which covered many thousands of miles over many tens of thousands of years to complete. The Genographic Project, a landmark study into ancient human migrations, aims to decode these hidden signposts within our DNA.

Einstein's letter to Roosevelt, August 2, 1939 UP to Leo Szilard Online In the summer of 1939, six months after the discovery of uranium fission, American newspapers and magazines openly discussed the prospect of atomic energy. However, most American physicists doubted that atomic energy or atomic bombs were realistic possibilities. No official U.S. atomic energy project existed. Leo Szilard was profoundly disturbed by the lack of American action. 'bat' calculator (Balkans-Anatolia-Turkic) I have decided to make a new calculator for DIYDodecad that may be useful for individuals from the Balkans and Anatolia. You can download it from here at Google Docs (or here from sendspace). The terms of use are the same as for DIYDodecad v 2.0. To run it, you simply extract the contents of the RAR file in your working directory, and type bat.par whenever you typed dv3.par in the instructions. The reference populations can be seen below.

Did early campfires trigger the emergence of tuberculosis? - Science News Posted Fire brought warmth and comfort to early humans but may also have triggered the emergence of deadly tuberculosis, Australian researchers suggest. Key points Tuberculosis first emerged in humans in Africa then spread to animalsMystery about how a benign microorganism became a killerHypothesis suggests fire increased human interaction and smoke made lungs more susceptible to disease Human Journey Everybody loves a good story, and when it's finished, this will be the greatest one ever told. It begins in Africa with a group of hunter-gatherers, perhaps just a few hundred strong. It ends some 200,000 years later with their six and a half billion descendants spread across the Earth, living in peace or at war, believing in a thousand different deities or none at all, their faces aglow in the light of campfires and computer screens.

The Elusive Theory of Everything A few years ago the city council of Monza, Italy, barred pet owners from keeping goldfish in curved fishbowls. The sponsors of the measure explained that it is cruel to keep a fish in a bowl because the curved sides give the fish a distorted view of reality. Aside from the measure’s significance to the poor goldfish, the story raises an interesting philosophical question: How do we know that the reality we perceive is true?

'africa9' calculator I have devised a new calculator targeted specifically for Africans. Admixture proportions in the reference panel, Fst distances between the K=9 components, as well as individual results for Project participants from the North_Africa_D, North_African_Jews_D and East_African_D populations can be seen in the spreadsheet. The calculator combines data from Henn et al. (2011), HGDP, and Behar et al. (2010). As a result, the number of SNPs is small: there is probably noise in the minor components, but the major components of one's ancestry should be well-defined. It should be used only by Africans and African-West Eurasian admixed individuals.

World-first genome study reveals rich history of Aboriginal Australians - Science News By Dani Cooper, additional reporting by Tom Forbes Posted The most comprehensive genomic study of Indigenous Australians to date has revealed modern humans are all descendants of a single wave of migrants who left Africa around 72,000 years ago. Key points Aboriginal and Papuan ancestors left Africa around 72,000 years agoArrived on supercontinent 'Sahul' around 50,000 years agoBy 31,000 years ago, most Aboriginal communities were genetically isolated from each other, giving rise to great genetic diversity Early Human Migration" No historical record exists that tracks the migratory patterns of the earliest humans. Scientists piece together the story of human migration by examining the tools, art and burial sites they left behind and by tracing genetic patterns. They accomplish this by looking at mitochondrial DNA (mtDNA), which is passed from a mother to her offspring without being blended with the genetic code of the father.
