    ...In recent years, dental calculus has emerged as an unexpected, but valuable, long-term reservoir of ancient DNA from dietary and microbial sources... Very little dental calculus was required for analysis--fewer than 25 milligrams per individual. This makes it possible to obtain high quality genetic ancestry information from very little starting material, an important consideration for archaeological remains... Although dental calculus preserves alongside skeletal remains, it is not actually a human tissue. Dental calculus, also known as tartar, is a calcified form of dental plaque that acquires human DNA and proteins passively, primarily through the saliva and other host secretions. Once...

    From the paper: In 1808 the Portuguese Crown declared “Just War” (Bellumiustum) against all Indian tribes that did not accept European laws (23). The fierce Botocudo were targeted in such wars and, in consequence, became virtually extinct by the end of the 19th century (24). Their importance for the history of the peopling of the Americas was revealed by studies reporting that the Botocudo had cranial features that consistently were described as intermediate between the polar Paleoamerican and Mongoloid morphologies (25, 26). Multivariate analyses of the cranial measures of different Amerindian and Paleoamerican groups from Brazil indeed concluded that the...

    DNA evidence lifted from the ancient bones and teeth of people who lived in Europe from the Late Pleistocene to the early Holocene -- spanning almost 30,000 years of European prehistory -- has offered some surprises, according to researchers who report their findings in the Cell Press journal Current Biology on Feb. 4, 2016. Perhaps most notably, the evidence shows a major shift in the population around 14,500 years ago, during a period of severe climatic instability... The researchers pieced this missing history together by reconstructing the mitochondrial genomes of 35 hunter-gatherer individuals who lived in Italy, Germany, Belgium, France,...

    Jean-Marie Loret, who died in 1985 aged 67, never met his father, but went on to fight Nazi forces during the Second World War. His extraordinary story has now been backed up by a range of compelling evidence, both in France and in Germany, which is published in the latest edition of Paris's Le Point magazine. Hitler is said to have had an affair with Mr Loret's mother, Charlotte Lobjoie, 16, as he took a break from the trenches in June 1917. Although he was fighting the French near Seboncourt, in the northern Picardy region, Hitler made his way to...

    Until his death in 1985, Jean-Marie Loret believed that he was the only son of Adolf Hitler. There is now renewed attention to evidence from France and Germany that apparently lends some credence to his claim. Loret collected information from two studies; one conducted by the University of Heidelberg in 1981 and another conducted by a handwriting analyst that showed Loret’s blood type and handwriting, respectively, were similar to the Nazi Germany dictator who died childless in 1945 at age 56. The evidence is inconclusive but Loret’s story itself was riveting enough to warrant some investigation. The French newspaper Le...

    Today, he believes Germany is doomed. "People there don't get married, and if they do they have one child," he says. "But the Turks and the other foreigners have many children. So it is a question of time that Germany will no longer be German." Why does he think this has happened? "I think it is a punishment for the Holocaust," he says, matter-of-factly. "Germany will leave the stage of history, no doubt about it." But the Jews, by contrast, will never die. This is a neat irony of history that he loves. "All the great cultures have left the...

    Getting to know the Hitlers (Filed: 20/01/2002) FOR more than 50 years, the relatives of Adolf Hitler have hidden under false names in Long Island, New York. They have not spoken publicly since the Second World War. In a revelatory new book to be launched this week, they break their silence. David Gardner tells their story. The faint lilt of German folk music floated through the open window of the dark-wood alpine bungalow as I walked down the short path to the front door. The property straddled two small roads on a forested private estate nestling into one of the ...

    Matias Goering is a direct descendant of Hitler's right-hand man and the commander of the Nazi air force. He also keeps Shabbat, wears a kippa, and identifies with the Greater Israel vision of West Bank settlers If Field Marshall Hermann Goering, commander of the Nazi Air Force and Hitler's right-hand man, knew how his descendant Matias Goering was living today, he'd surely roll over in his grave. Matias Goering , a distant relative of the senior Nazi (his great grandfather was Goering's grandfather's brother) wears a kippa and keeps kosher, observes Shabbat and wears an orange anti-disengagement bracelet reading 'Jews...

    DNA tests have revealed Adolf Hitler may have been related to both Jews and black people that he earmarked for extermination. Brussels news magazine Knack has claimed that DNA obtained from the Nazi leader's relatives living in America led to the discovery. Journalist Jean-Paul Mulders garnered the DNA from a serviette dropped by one of three known Hitler descendants who live on Long Island, New York. That led earlier this year to the tracking down in Austria of a farmer known only as Norbert H. who was found to be a cousin of the German dictator. Mulders used the services...

    Geneticists from the University of Leicester have discovered that most European men descend from just a handful of Bronze Age forefathers, due to a 'population explosion' several thousand years ago. The project, which was funded by the Wellcome Trust, was led by Professor Mark Jobling from the University of Leicester's Department of Genetics and the study is published in the journal Nature Communications. The research team determined the DNA sequences of a large part of the Y chromosome, passed exclusively from fathers to sons, in 334 men from 17 European and Middle Eastern populations. This research used new methods for...

    Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on. Researchers found that naturally occurring changes to these proteins, which affect how they control genes, can be sustained from one generation to the next and so influence which traits are passed on. The finding demonstrates for the first time...

    The London Telegraph ^ | June 4, 2015 | Sarah Knapton, Science Editor
    Scientists now know that our DNA is being altered all the time by environment, lifestyle and traumatic events. Genetic faults caused by trauma, poor lifestyle or environmental stress can be passed down to future generations, scientists at the University of Cambridge have discovered. Previously large studies have shown that devastating events such as famine can scar future generations, making them more prone to obesity and diabetes. However it is the first time that the biological mechanism for the effect has been seen. Although the same genes are passed down through generations, scientists now know that our DNA is being altered...

    Graham Williams at the University of Huddersfield, UK, has a different way – to look for modifications to the twins' DNA that have come about as a result of their lifestyles. Such epigenetic changes occur when a chemical group known as a methyl group attaches to a gene and modifies the way it is expressed. This happens as a body is influenced by a person's environment, lifestyle and disease. Williams's team took mouth swabs from five pairs of twins. After extracting the DNA from each sample, the group used a chemical to target parts of the DNA that did not...
  • An Algorithm Set To Revolutionize 3-D Protein Structure Discovery

    MIT Technology Review ^ | April 23, 2015
    One of the great challenges in molecular biology is to determine the three-dimensional structure of large biomolecules such as proteins. But this is a famously difficult and time-consuming task. The standard technique is x-ray crystallography, which involves analyzing the x-ray diffraction pattern from a crystal of the molecule under investigation. That works well for molecules that form crystals easily. But many proteins, perhaps most, do not form crystals easily. And even when they do, they often take on unnatural configurations that do not resemble their natural shape. So finding another reliable way of determining the 3-D structure of large biomolecules...

    Sue Docken’s start in life, in 1951, with a no-questions-asked cash adoption at the hands of a midwife, had strong elements of the crime scene that it was. Her adoptive father was told to stay in the car and keep the motor running. His wife went into a nondescript office building in Butte, Mont., where she met with the midwife, Gertrude Pitkanen, and was handed the hours-old infant and the afterbirth, offered a peek through a curtain at the young mother lying in a bed, and told to leave. The afterbirth was thrown out the window on the drive home,...

    Unearthed, the prince of Stonehenge By Roger Highfield (Filed: 21/08/2002) A prehistoric prince with gold ear-rings has been found near Stonehenge a few yards away from the richest early Bronze Age burial in Britain. Earlier this year, archaeologists found an aristocratic warrior, also with gold ear-rings, on Salisbury Plain and speculated that he may have been an ancient king of Stonehenge. The body was laid to rest 4,300 years ago during the construction of the monument, along with stone arrow heads and slate wristguards that protected the arm from the recoil of the bow. Archaeologists named him the Amesbury Archer....

    Just one gram of DNA can store the equivalent of 14,000 Blu-ray discs. But although the potential for DNA as an alternative to hard drives has been known about for years, it is not the most reliable and secure way to keep data safe. The latest breakthrough could be about to change that, however.

    Oxford Journals, Genome Biology and EvolutionBurial site and skeletal remains of the St. Helena marine forager, who was at least 50 years old when he died DNA from a 2,300-year-old skeleton suggests that the earliest known group of modern humans to branch off from the wider genetic population survived until astonishingly recently. The finding supports the case that southern, rather than eastern, Africa is humanity's ancestral home.Mitochondrial DNA, passed on only from the mother, demonstrates that all humanity is descended from a single ancestor around 200,000 years ago. Archaeological evidence points to the Omo Valley, where fossil evidence suggests that Homo sapiens roamed Africa 195,000...

    Oetzi, the prehistoric man frozen in a glacier for 5,300 years, could have been infertile, a new study suggests. Genetic research, published in the American Journal of Physical Anthropology, also confirms that his roots probably lie in Central Europe. Oetzi's body was found in the melting ice of the Schnalstal glacier in the Italian Alps in 1991. Examination of his remains has already revealed the Copper Age man almost certainly died as a result of a fight. The assessment is based on the presence of an arrowhead that is lodged in his back and extensive cuts to his hands. The...

    Stone Age man found frozen in the Alps some 5,300 years after he was murdered under mysterious circumstances may have been a childless social outcast, a new study showed. Italian anthropologist Franco Rollo studied fragments of the DNA belonging to Oetzi, as the mummy has come to be known, and found two typical mutations common among men with reduced sperm mobility, the museum that stores the "iceman" said. A high percentage of men with such a condition are sterile. "Insofar as the 'iceman' was found to possess both mutations, the possibility that he was unable to father offspring cannot be...
