The death of King Albert I of Belgium in 1934 -- officially a climbing accident -- still fuels speculation. Forensic geneticist Maarten Larmuseau and his colleagues at KU Leuven (University of Leuven, Belgium), have now compared DNA from blood found on the scene in 1934 to that of two distant relatives. Their analysis confirms that the blood really is that of Albert I. This conclusion is at odds with several conspiracy theories about the king's death.

On 17 February 1934, King Albert I -- the third King of the Belgians -- died after a fall from the rocks in Marche-les-Dames, in the Ardennes region of Belgium near Namur. Albert I was popular and world famous due to his role during the First World War. The fact that there were no witnesses to his death soon fuelled speculations about the king's 'real' cause of death.

Conspiracy theories are circulating to this very day, ranging from a political murder to a crime of passion: the king is said to have been murdered elsewhere, his dead body allegedly never was in Marche-les-Dames, or his fall is believed to have been staged only later. Evidence for these theories, however, has never been found.

After the death of Albert I, Marche-les-Dames virtually became a place of pilgrimage, and relics turned up with the king's trails of blood, said to have been collected during the night of 17 to 18 February by people living in the neighbourhood.

VTM journalist Reinout Goddyn, who works for the Flemish television programme Royalty, bought one of these relics: blood-stained tree leaves. He wanted to know if this could really be the blood of Albert I, given the conspiracy theories. In 2014, UGent Professor Dieter Deforce had already confirmed that the blood was definitely human.

Forensic geneticist Maarten Larmuseau and his colleagues from KU Leuven (University of Leuven, Belgium) continued the investigation and found two living relatives of Albert I: "King Simeon II of Saxe-Coburg and Gotha, the last tsar and former prime minister of Bulgaria who is related to Albert I on his father's side, and Anna Maria Freifrau von Haxthausen, a German baroness who is related to Albert I on her mother's side, were willing to cooperate. They gave up DNA samples that we compared with the DNA of the trails of blood. We found that the blood is indeed that of Albert I."

This confirmation has historical importance. "80 years after the fact, everyone involved has passed away, and most material is gone; we will probably never be able to dismiss all speculations concerning this 'cold case'. This study was one of the last possibilities to gather additional data. The authenticity of the trails of blood confirms the official account of the death of Albert I. The story that the dead body of the king has never been in Marche-les-Dames or was only placed there at night has now become very improbable. Furthermore, the results show that conducting a perfect legal investigation at the time was impossible right from the start, because souvenir hunters had disturbed the scene."

This type of genetic family-tree research confronts researchers with quite a few ethical questions, adds bioethicist Pascal Borry from the KU Leuven Interfaculty Centre for Biomedical Ethics and Law: "We have to take into account the consequences of this study for living relatives. After all, in addition to the actual identification, a genetic profile can reveal quite a bit of sensitive information, in the context of a kinship analysis or in terms of hereditary conditions. This particular case concerns someone who's deceased and has obviously never given permission for a genetic profile."

"We only focused on the identification of the trails of blood and deliberately avoided deducing unexpected results from the DNA," Larmuseau continues. "The latter was the most difficult aspect of this study. We also want to protect the privacy of everyone involved and of living relatives, and avoid commercialization of the genetic information, following international guidelines for biomedical research. Therefore, the genetic profiles have not been published, but they were double-checked by independent experts. The DNA samples of our study have been destroyed. What is left of the relic will be entrusted to an institution for cultural heritage or a scientific institution."

Prof. Nicholas Conard and members of his team, present the discovery of a tool used to make rope in today‘s edition of the journal: Archäologische Ausgrabungen Baden-Württemberg.

Rope and twine are critical components in the technology of mobile hunters and gatherers. In exceptional cases impressions of string have been found in fired clay and on rare occasions string was depicted in the contexts of Ice Age art, but on the whole almost nothing is known about string, rope and textiles form the Paleolithic.

A key discovery by Conard’s team in Hohle Fels Cave in southwestern Germany and experimental research and testing by Dr. Veerle Rots and her team form the University of Liège is rewriting the history of rope.

The find is a carefully carved and beautifully preserved piece of mammoth ivory 20.4 cm in length with four holes between 7 and 9 mm in diameter. Each of the holes is lined with deep, and precisely cut spiral incisions. The new find demonstrates that these elaborate carvings are technological features of rope-making equipment rather than just decoration.

Similar finds in the past have usually been interpreted as shaft-straighteners, decorated artworks or even musical instruments. Thanks to the exceptional preservation of the find and rigorous testing by the team in Liège, the researchers have demonstrated that the tool was used for making rope out of plant fibers available near Hohle Fels. “This tool answers the question of how rope was made in the Paleolithic”, says Veerle Rots, “a question that has puzzled scientists for decades.”

Excavators found the rope-making tool in archaeological horizon Va near the base of the Aurignacian deposits of the site. Like the famous female figurines and the flutes recovered from the Hohle Fels, the rope-making tool dates to about 40,000 years ago, the time when modern humans arrived in Europe. The discovery underlines the importance of fiber technology and the importance of rope and string for mobile hunters and gatherers trying to cope with challenges of life in the Ice Age.

Prof. Conard’s team has excavated at Hohle Fels over each of the last 20 years, and it is this long-term commitment that has over and over again paid off, to make Hohle Fels one of the best known Paleolithic sites worldwide. Hohle Fels and neighboring sites from the Ach and Lone Valleys have been nominated for UNESCO World Cultural Heritage status. The excavations at Hohle Fels near Schelklingen in the Ach Valley are funded by the HeidelbergCement AG, the Ministry of Science of Baden-Württemberg and the Heidelberger Academie of Sciences.

The rope-making tool will be on exhibit at the Urgeschichtliches Museum in Blaubeuren starting Saturday, July 23rd . (www.urmu.de)

An ancient latrine near a desert in north-western China has revealed the first archaeological evidence that travellers along the Silk Road were responsible for the spread of infectious diseases along huge distances of the route 2,000 years ago.

Cambridge researchers Hui-Yuan Yeh and Piers Mitchell used microscopy to study preserved faeces on ancient 'personal hygiene sticks' (used for wiping away faeces from the anus) in the latrine at what was a large Silk Road relay station on the eastern margins of the Tarim Basin, a region that contains the Taklamakan desert. The latrine is thought to date from 111 BC (Han Dynasty) and was in use until 109 AD.

They found that eggs from four species of parasitic worm (helminths) were present: roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), tapeworm (Taenia sp.), and Chinese liver fluke (Clonorchis sinensis).

Chinese liver fluke is a parasitic flatworm that causes abdominal pain, diarrhea, jaundice and liver cancer. It requires well-watered, marshy areas to complete its life cycle. Xuanquanzhi relay station was located at the eastern end of the arid Tarim Basin, an area that contains the fearsome Taklamakan Desert. The liver fluke could not have been endemic in this dry region.

In fact, based on the current prevalence of the Chinese liver fluke, its closest endemic area to the latrine's location in Dunhuang is around 1,500km away, and the species is most common in Guandong Province -- some 2,000km from Dunhuang.

Researchers from the University of Cambridge's Department of Archaeology and Anthropology, who conducted the study, suggest that the traveller infected with this liver fluke must have journeyed an enormous distance, and suggest the discovery provides the first reliable evidence for long distance travel with an infectious disease along the Silk Road.

The findings are published today in the Journal of Archaeological Science: Reports.

"When I first saw the Chinese liver fluke egg down the microscope I knew that we had made a momentous discovery," said Hui-Yuan Yeh, one of the study's authors. "Our study is the first to use archaeological evidence from a site on the Silk Road to demonstrate that travellers were taking infectious diseases with them over these huge distances."

The Silk Road (or Silk Route) came to prominence during the Han Dynasty in China (202 BC -- AD 220) as merchants, explorers, soldiers and government officials journeyed between East Asia and the Middle East/Mediterranean region.

Researchers have previously suggested that diseases such as bubonic plague, anthrax and leprosy might have been carried by ancient travellers along the legendary trading route, as similar strains have been found in China and Europe.

"Until now there has been no proof that the Silk Road was responsible for the spread of infectious diseases. They could instead have spread between China and Europe via India to the south, or via Mongolia and Russia to the north," says study lead Piers Mitchell.

The Cambridge team worked alongside Chinese researchers Ruilin Mao and Hui Wang from the Gansu Institute for Cultural Relics and Archaeology, who originally excavated the ancient latrine and relay station in Ganzu Province.

The stop was a popular one on the Silk Road with travellers staying there and government officials using the facility to change their horses and deliver letters. While excavating the latrine, the Chinese team found the personal hygiene sticks with cloth wrapped round one end.

Added Mitchell: "Finding evidence for this species in the latrine indicates that a traveller had come here from a region of China with plenty of water, where the parasite was endemic. This proves for the first time that travellers along the Silk Road really were responsible for the spread of infectious disease along this route in the past."
