    Ancient DNA recovered from a series of skeletons in central Germany up to 7500 years old has been used to reconstruct the first detailed genetic history of modern Europe. The study, published today in Nature Communications, reveals a dramatic series of events including major migrations from both Western Europe and Eurasia, and signs of an unexplained genetic turnover about 4000-5000 years ago. The research was performed at the University of Adelaide's Australian Centre for Ancient DNA (ACAD). Researchers used DNA extracted from bone and teeth samples from prehistoric human skeletons to sequence a group of maternal genetic lineages that are...

    Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation -- the addition of a methyl group of molecules to a DNA strand -- is one of the ways gene expression is regulated. The findings appear in the current issue of Scientific Reports (Nature Publishing Group). "While nanopores have been studied for genomic sequencing and screening analysis, this new assay can potentially circumvent the need for some of the current processes in evaluating epigenetics-related diseases," says George Vasmatzis, Ph.D., co-leader of Mayo's Biomarker Discovery Program in the Center for Individualized...

    Complexity of Cell's 'Molecular Shredder' Revealed by Jeffrey Tomkins, Ph.D. * When genes in the cell are turned on, the result is the production of gene copies called messenger RNAs, or mRNAs. The mRNAs are then used as templates to make proteins, the key molecules that enable the cell to function. But what happens to the excess mRNAs when they are no longer needed or the RNAs that have errors in them? They certainly can't remain active in the cell or serious problems would ensue. A good analogy for the cell's solution to this problem is the example of a...

    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...

    The Resurrection of 'Junk DNA'? by Nathaniel Jeanson, Ph.D., and Brian Thomas, M.S. * Evolutionists are protesting. What has them so agitated? The results of the most in-depth human genome study to date, called the "ENCODE" project, revealed that 80 percent or more of the human genome appears to have some use in the set of human body tissues they investigated.1 This contrasts starkly to the evolutionary claim that "roughly 45 percent of the human genome [is] made up of such genetic flotsam and jetsam"2 or "junk DNA." ENCODE includes scores of researchers worldwide who sequence human DNA and measure...

    Vladimir I. shCherbak of al-Farabi Kazakh National University of Kazakhstan, and Maxim A. Makukov of the Fesenkov Astrophysical Institute, hypothesize that an intelligent signal embedded in our genetic code would be a mathematical and semantic message that cannot be accounted for by Darwinian evolution. They call it “biological SETI.” What’s more, they argue that the scheme has much greater longevity and chance of detecting E.T. than a transient extraterrestrial radio transmission. Writing in the journal Icarus, they assert: “Once fixed, the code might stay unchanged over cosmological timescales; in fact, it is the most durable construct known. Therefore it represents...

    The discovery of the structure of DNA and the subsequent developments in genetics and genomics have had a great impact on all of the biological sciences, including human evolution. Our ideas about human evolution 60 years ago came primarily from the fossil and archaeological records. These fields revealed that the last two million years were a dynamic period of our evolutionary history. The human lineage two million years ago was a population with ape-sized brains limited to sub-Saharan Africa. The human lineage expanded into Eurasia around 1.85 million years ago, and our brain size increased throughout the Pleistocene. Anatomically modern...

    UA geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex. The new divergent lineage, which was found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record. The results are published in the American Journal of Human Genetics. "Our analysis indicates this lineage diverged from previously known Y chromosomes about 338,000 ago, a time when anatomically modern humans had not...

    It’s not exactly news that China is setting itself up as a new global superpower, is it? While Western civilization chokes on its own gluttony like a latter-day Marlon Brando, China continues to buy up American debt and lock away the world’s natural resources. But now, not content to simply laugh and make jerk-off signs as they pass us on the geopolitical highway, they’ve also developed a state-endorsed genetic-engineering project. At BGI Shenzhen, scientists have collected DNA samples from 2,000 of the world’s smartest people and are sequencing their entire genomes in an attempt to identify the alleles which determine...

    Johnny Williams spent 14 years in prison for an attempted rape he never committed. On Friday, a judge overturned his conviction. And on Tuesday, the 37-year-old Williams spoke publicly for the first time. "I'm truly happy," Williams said in a one-on-one interview at Santa Clara University. That's where a team of students and lawyers from the Northern California Innocence Project helped prove that the DNA on a 9-year-old's T-shirt did not belong to him. The DNA is what led to his 1998 attempted rape arrest. "Everything happens for a reason," he said.

    Russian Bigfoot DNA Analyzed By Scientists: Yeti Or Yogi? Bigfoot DNA is in the news again. Over the last three years, the Russian Bigfoot, or Yeti, was claimed to be a “towering, long-haired beast roaming the Mount Shoria region of southern Russia.” This potential Bigfoot has left clumps of hair in caves that scientists have just now analyzed. Professor Bryan Sykes of Oxford’s Wolfson Institute has led a global genetics project to test hair samples from possible Bigfoots. Professor Sykes told The Sun what he thought about this Bigfoot DNA: “The hairs did not come from a yeti. The American...

    The Aztecs who conquered the city of Xaltocan in ancient Mexico around 1435 may have fundamentally changed the genetic makeup of the people who lived there, new research suggests... Xaltocan was the capital of a pre-Aztec city-state ruled by the Otomi, an indigenous people who lived in Mexico. The period before the Aztec conquest was a tumultuous time for the Otomi, when a century of warfare led to the collapse of their capital city. Colonial records from the 1500s onward told tales of the Otomi fleeing the city en masse in 1395. Those records suggested that the city was abandoned...

    Epigenetics: How Our Experiences Affect Our Offspring New research suggests that people's experiences, not just their genes, can affect the biological legacy of their offspring By The Week Staff January 20, 2013 Isn't our genetic legacy hardwired? From Mendel and Darwin in the 19th century to Watson and Crick in the 20th, scientists have shown that chromosomes passed from parent to child form a genetic blueprint for development. But in a quiet scientific revolution, researchers have in recent years come to realize that genes aren't a fixed, predetermined program simply passed from one generation to the next. Instead, genes can...

    He wore the English crown, but he ended up defeated, humiliated and reviled. Now things are looking up for King Richard III. Scientists announced Monday that they had found the monarch's 500-year-old remains under a parking lot in the city of Leicester -- a discovery Richard's fans say will inspire new research into his maligned history. University of Leicester researchers say tests on a battle-scarred skeleton unearthed last year prove "beyond reasonable doubt" that it is the king, who died at the Battle of Bosworth Field in 1485, and whose remains have been missing for centuries. "Richard III, the last...

    Computerworld - Researchers have created a way to store data in the form of DNA, which can last for tens of thousands of years. The encoding method makes it possible to store at least 100 million hours of high-definition video in about a cup of DNA, the researchers said in a paper published in the journal Nature this week.
