Identifying Saxon Princess Eadgyth

When German archaeologists discovered bones in the tomb of Queen Eadgyth in Magdeburg Cathedral, they looked to Bristol to provide the crucial scientific evidence that the remains were indeed those of the English royal. Dr Alistair Pike in the Department of Archaeology and Anthropology tells Hannah Johnson how tiny samples of tooth enamel proved the identity of a Saxon queen.

Teeth provide remarkable evidence about the early years of an individual’s life. The region where a person grew up can be traced in the tooth enamel laid down in their first 14 years because strontium and oxygen isotope ratios in the teeth reflect the food a person ate and the water they drank.

First Americans 'Reached Europe Five Centuries Before Columbus Voyages'

Scientists tracing the genetic origins of an Icelandic family believe the first American arrived in Europe around the 10th century, a full five hundred years before Columbus set off on his first voyage of discovery in 1492.

Norse sagas suggest the Vikings discovered the Americas centuries before Columbus and the latest data seems to support the hypothesis that they may have brought American Indians back with them to northern Europe.

When Genetics and Genealogies Tell Different Stories - Maternal Lineages in Gaspesia

Data from uniparentally inherited genetic systems were used to trace evolution of human populations. Reconstruction of the past primarily relies on variation in present-day populations, limiting historical inference to lineages that are found among living subjects.

Our analysis of four population groups in the Gaspé Peninsula, demonstrates how this may occasionally lead to erroneous interpretations. Mitochondrial DNA analysis of Gaspesians revealed an important admixture with Native Americans.

Scientists Exhume Body of Famed 16th Century Astronomer Tycho Brahe to Finally Solve Murder Mystery

An international team of scientists was opening the tomb of a famous 16th-century Danish astronomer Tycho Brahe in an effort to shed light on his sudden and mysterious death. Brahe, born in 1546, had been in Prague at the invitation of the Holy Roman Emperor Rudolph II after leaving his scientific observatory on the island of Hven after a falling-out with the Danish king.

Brahe is believed to have been taking medicine that contained some mercury as a pain-reliever in the last few weeks of his life.

DNA Reveals Origins of First European Farmers

A team of international researchers led by ancient DNA experts from the University of Adelaide has resolved the longstanding issue of the origins of the people who introduced farming to Europe some 8000 years ago.

A detailed genetic study of one of the first farming communities in Europe, from central Germany, reveals marked similarities with populations living in the Ancient Near East (modern-day Turkey, Iraq and other countries) rather than those from Europe.

DNA Fingerprinting Traces Global Path of Plague

Researchers from Ireland, China, France, Germany and the United States, including Northern Arizona University's Paul Keim and David Wagner, have turned back the clock to examine the past 10,000 years of global plague disease events. Their findings regarding the plague pathogen, Yersinia pestis, will be published in an upcoming issue of the journal, Nature Genetics.

Tracing its evolution, the plague spread over various historical trade routes as early as the 15th century. Chinese admiral and explorer Zheng He's travels may have taken the plague to central Africa. The Silk Road, which led from China to Western Asia and on to Europe as described by Marco Polo, also may have served as an avenue for disease. The latest plague pandemic of the late 1800s still persists today in wild rodents throughout the western United States.

DNA Shows Remains are Romania Ex-Dictator Ceausescu

DNA tests confirmed Romanian communist dictator Nicolae Ceausescu was buried in a grave in Bucharest, forensic experts said on Wednesday, lifting doubt over the ruler's burial place.

Ceausescu ruled Romania from 1965 until he and his wife Elena were captured and shot by firing squad on Christmas Day in 1989 after fleeing mass protests in Bucharest, marking the fall of communism in the southeast European country.

Ozzy Osbourne Related to Vesuvius Survivors

Rock wildman Ozzy Osbourne has discovered how he managed to survive 40 years of drink and drug abuse - he's descended from Romans who lived through the eruption of Mount Vesuvius. The former Black Sabbath frontman has undergone complicated DNA testing for research scientists to map out his entire genetic make-up.

Experts were then able to use his profile to determine his possible ancestors - and the rocker discovered he is related to legendary U.S. outlaw Jesse James and Romans who survived the Vesuvius eruption in the year 79 AD.

Genetic Analysis of the Presumptive Blood from Louis XVI, King of France

A text on a pyrographically decorated gourd dated to 1793 explains that it contains a handkerchief dipped with the blood of Louis XVI, king of France, after his execution. Biochemical analyses confirmed that the material contained within the gourd was blood.

The mitochondrial DNA (mtDNA) hypervariable region 1 (HVR1) and 2 (HVR2), the Y-chromosome STR profile, some autosomal STR markers and a SNP in HERC2 gene associated to blue eyes, were retrieved, and some results independently replicated in two different laboratories.

Missing WWII Soldiers Identified by DNA Testing

The Rockford Register Star reports that 24-year old Robert R Bishop, a second lieutenant in the 392nd Bombardment Group of the USAF, was last seen in April 29, 1944. During a mission in Hanover, Germany, Bishop's plane went down and for most of the past century his body remained undiscovered.

However, in 2003, a group of excavators in Europe uncovered the wreckage of his B-24 bomber and returned his body to the US military. Following seven years of processing, DNA tests conducted on the body were matched with samples provided by Mr Bishop's family on July 29th, 2009.

DNA Test Solves Mystery Of A Brother's Death In Korean War

On a cold November night in 1950, the town marshal knocked on the side door of Mary K. Mitchell's family home in Cloverport, Ky. The telegram in his hand carried a devastating message: U.S. Army Cpl. Charles Patterson "Pat" Whitler, Mitchell's 22-year-old brother, was missing in action in the Korean War.

Mitchell, 66, a hair salon receptionist, was 6 years old when her parents got the news. Mitchell's father suffered a fatal heart attack that same night, leaving her mother to raise nine children, six of them under the age of 16.

'Mitochondrial Eve': Mother of All Humans Lived 200,000 Years Ago

The most robust statistical examination to date of our species' genetic links to "mitochondrial Eve" -- the maternal ancestor of all living humans -- confirms that she lived about 200,000 years ago. The Rice University study was based on a side-by-side comparison of 10 human genetic models that each aim to determine when Eve lived using a very different set of assumptions about the way humans migrated, expanded and spread across Earth.

"Our findings underscore the importance of taking into account the random nature of population processes like growth and extinction," said study co-author Marek Kimmel, professor of statistics at Rice.

Ancient DNA Experts Say They Are Analyzing A Lock Of Sitting Bull's Hair

Craig Venter and James Watson have done it, as has an African bushman named !Gubi and a handful of others. Now legendary Sioux chief Sitting Bull may be joining the small but growing number of people who have had their DNA sequenced.

Earlier this year, a research team led by Eske Willerslev, an ancient DNA expert at the University of Copenhagen, reported sequencing the complete genome of a native Greenlander who lived 4,000 years ago. It was the first full human genome published based on ancient DNA.

Team member Valdiosera said that the researchers have the approval of Sitting Bull’s descendents to perform DNA tests on a sample of his hair, and that the team is trying to extract a full genome. If so, his would become the first ancient, non-frozen, Native American genome sequenced.
