The Hundred Years War might not be quite over just yet with an apparent Franco-British row brewing over Joan of Arc's gold-plated ring.

Just as the historic gold-plated ring was safely back in French hands it’s emerged that British authorities want it back.

The saga of Joan of Arc’s ring took a new twist on Sunday just as it was officially unveiled on its return to France.

The ring thought to belong toFrance's most famous historical martyr, Joan of Arc, was unveiled on Sunday at the Puy de Fou historical theme park in the western Vendee region.

Some 5,000 spectators turned out to see the unveiling of the ring, that the park had bought at a London auction for €376, 833 ($425,000).

"It's a little bit of France that has returned. The ring has come back to France and will stay here," said Philippe de Villiers, the founder of Puy de Fou told the crowd.

The ring had thought to have been in Britain for over six centuries and de Villiers told spectators that there was “a new twist” in the story of the ring.

“The British government has sent our lawyer an unprecedented demand: the return of the ring to London,” de Villers told the shocked crowd.

“We are told that the National Arts Council considers this ring part of those objects with, and I quote ‘high national symbolic value’ and as such should have part of a special legislation.”

According to the demand, on purchasing the ring the Puy de Fou park should have obtained a special export license necessary under European regulations.

De Villiers said that they had checked the rules and claimed they only apply if the object is taken out of the European Union.

He then mocked the British and the potential of a Brexit fro the EU by telling the crowd: “It is not at all our intention to have a Puy de Fou exit.

He then sent a defiant message to the British government.

“Ladies and gentlemen from Britain, if you want to see the ring, then come to the Puy de Fou. For the rest it’s too late,” he said.

Joan of Arc, who fought against the English occupation of France during the Hundred Years' War, was burned alive at the stake but became a symbol of French resistance and was later made a saint by the Catholic Church.

The official unveiling saw the ring carried on a cushion in a wooden ark, with its own honour guard and a military procession.

The gold-plated silver ring was dated to the 15th century by an Oxford laboratory, but the trove of historical documents that came with it have yet to prove it belonged to the famous French martyr.

"They are only at the start of the exploration. It's a lot of work but a beautiful adventure," said expert Vanessa Soupault, who saw the ring recently.

The bulky piece of jewellery features three engraved crosses and the inscription "JHS-MAR", signifying "Jesus-Maria".

That fits a description recorded at Joan of Arc's trial in 1431, where she told the court the ring had been given by her parents.

Puy du Fou says the ring was probably enlarged and modified at some point in the last 200 years.

However the difficulty of tracing the ring's path through the centuries has left many historians sceptical.

Part of the problem is the number of copies in circulation. There was even a tombola in the early 20th century in which prizes included versions of the ring.

"Around Joan of Arc, we already have several cases of false objects," said Olivier Bouzy, head of the Joan of Arc archives in the north-central French town of Orleans

French President Francois Hollande and archaeological officials have used an exhibit in Paris of two preserved ancient Egyptian cities as a defiant example that the world will not be cowed by Islamic State militants who recently destroyed ancient Syrian heritage sites in Palmyra and killed a local archaeologist.

The exhibit at Paris' Arab World Institute, Osiris, Egypt's Sunken Mysteries, presents about 250 ancient objects that were recovered after a French archaeologist discovered the legendary cities Thonis/Heracleion and Canopus underwater over a decade ago.

Much like the mystery of ancient Atlantis, the cities had been lost somewhere between myth, history and legend — that is, until French archaeologist Franck Goddio made his landmark discovery in 2000 uncovering the sites in their watery grave near Alexandria. They had miraculously been preserved by sea sediment for nearly 2,000 years.

"This exhibit is an incredible achievement," Goddio told The Associated Press. "For years, these cities seemed lost to the world — submerged because of natural calamities like earthquakes and big tides... And now here they are — being shown to the public for the first time. Some objects only came out of the water last year and others have never left Egypt before."

The underwater excavation is ongoing with a team of 50, and Goddio estimates that only as little as 3 percent of the ancient cities have been uncovered so far.

Hollande, who inaugurated the exhibit this week, alongside the Egyptian minister of antiquities and minister of tourism, said that the message of this exhibit went far beyond Egypt — and said it showed how the will to preserve world heritage is stronger that the wish to annihilate it.

"This exhibit is a message, a fighting message that we have preserved these artifacts, a message of hope at a time when the Middle East is undergoing such drama," he said.

In the last weeks, Islamic State militants destroyed the two-millennia-old temple of Bel, The Temple of Baalshamin, as well as three ancient tower tombs in the central city of Palmyra — what UNESCO has called an "intolerable crime against civilization."

Hollande also paid his respects to the "sacrifice" of Khaled al-Asaad, the former director of the destroyed Palmyra heritage sites and one of the most important pioneers in Syrian archaeology in the 20th century, who was killed by Islamic State militants.

The exhibit was presented in collaboration with the Egyptian government, with officials keen to use this as a way to show that there's another face to the Arab world as the one being projected by militants.

"What is going on in Syria, like the destruction of Palmyra and in Iraq, this kind of thinking is not the real beliefs of the area. This exhibit shows it. This preservation of culture here in Paris shows that it's just a minority who somehow took the lead that are doing this damage," said Mohamed Abdelmaguid, the general director of the Central Department of Underwater Antiquities in Egypt.

The many thousands expected to visit the Osiris exhibit in the coming months, as it travels to London's British Museum, might not be drawn for their knowledge of current affairs, and be just be attracted by beauty of the artifacts.

The objects — like a beautiful and imposing 5-meter (16-feet) granite statue of the god Osiris, tools, and ritualistic objects — are in often near-perfect condition, and offer a rare public glimpse into the vast achievements of the ancient world.

The exhibit runs until Jan. 31.

A gruesome discovery in eastern France casts new light on violent conflicts that took lives — and sometimes just limbs — around 6,000 years ago.

Excavations of a 2-meter-deep circular pit in Bergheim revealed seven human skeletons plus a skull section from an infant strewn atop the remains of seven human arms, say anthropologist Fanny Chenal of Antea Archéologie in Habsheim, France, and her colleagues.

Two men, one woman and four children were killed, probably in a raid or other violent encounter, the researchers report in the December Antiquity. Their bodies were piled in a pit that already contained a collection of left arms hacked off by axes or other sharp implements. Scattered hand bones at the bottom of the pit suggest that hands from the severed limbs had been deliberately cut into pieces.

It’s unclear who the arms belonged to. All the Bergheim skeletons have both their arms except for a man with skull damage caused by violent blows. His skeleton lacks a left arm, the researchers say. They have been unable to determine whether that arm ended up in the pit.

Chenal’s group doesn’t know whether attackers targeted victims’ left arms for a particular reason. The arms could have been taken as war trophies, the team speculates.

Radiocarbon dating of two bones indicates that individuals in the Bergheim pit lived roughly 6,000 years ago. From 6,500 to 5,500 years ago, during what’s known as the Neolithic period, one of the many ways of disposing of the dead in farming communities throughout Central and Western Europe was in circular pits.

Discoveries of human and nonhuman bones, as well as pottery, in these pits go back more than a century. The Bergheim pit provides the first evidence that people killed and mutilated in raids or battles were sometimes buried in circular pits, too, says study coauthor Bruno Boulestin, an anthropologist at the University of Bordeaux in France.

Unusual deposits in Neolithic circular pits, such as attack victims and severed limbs at Bergheim, “may have been more common than previously expected,” says biological anthropologist Silvia Bello of the Natural History Museum in London, who did not participate in the new study. She suspects, for instance, that closer inspection of human bones previously found in circular pits elsewhere in Europe will reveal additional instances of violent deaths from a time when armed conflicts occurred between some communities.

Bergheim’s brutalized victims spice up attempts to make sense of Neolithic circular pits. Many researchers regard these pits as remnants of storage silos that were put to other uses, possibly as receptacles for the bodies of people deemed unworthy of formal burials.

Others argue that a large proportion of pits were dug as graves for high-ranking individuals, whose servants or relatives were killed to accompany them. Or, slaves might have been killed and put in pits as displays of wealth or as sacrifices to gods.

Of 60 circular pits excavated in Bergheim in 2012 in advance of a construction project, 14 contained human bones. The researchers found skeletons or isolated bones of at least one to five individuals in each of 13 pits. The final pit contained the bodies and limbs described in the new paper.

Joints of severed arms and skeletons in that pit were well-preserved, indicating that all had been placed there at or around the same time with a minimum amount of jostling disturbance. The pit also contained remains of a piece of jewelry made with a mussel’s valve, a stone arrowhead, a fragment of a pig’s jaw and two hare skeletons. The skeleton of a woman who had been put in the pit later lay on top of a sediment layer encasing those finds.

Neither that woman nor human remains in the other Bergheim pits showed signs of violent death or limb loss.

Archaeologists from the UK working in the Channel Island of Jersey have found the remains of a 14,000-year-old hunter-gather settlement offering great views over landscapes now drowned by the English Channel.

The site, called Les Varines, is located in the Jersey parish of St Saviour and has produced over 5,000 scattered stone artefacts during the past five years of excavation. But the team has unearthed denser concentrations of tools and burnt bone and, for the first time, fragments of engraved stone. These are currently under study in an attempt to unravel the significance of these unique finds.

Dr Chantal Conneller, a Co-Director of the project from The University of Manchester, said “We knew from the beginning that Les Varines was an important site. There is nothing of its size or scale elsewhere in the British Isles but there are parallels in France and Germany. Previously we had recovered stone artefacts disturbed by later mud flows, but now it seems we have found the well preserved edges of the settlement itself. Incised stones can be common on Magdalenian camps, many are known from sites in the Germany and the south of France, where they are often seen to have a magical or religious use. However they are rare in Northern France and the British Isles, making this a significant find. Although we are not yet sure of the exact age of the campsite, it might well represent some of the first hunter-gather communities to recolonise the north of Europe after coldest period of the last Ice Age”.

The work was carried out by a team from The University of Manchester and University College London.

Dr Ed Blinkhorn, of UCL Institute of Archaeology, who led the excavations, said “This has been the culmination of five years of patient work, tracing thousands of flint tools within slope deposits back to the mother lode. We knew a significant hunter-gatherer camp lay in this field and it seems we’ve finally found it.”

The settlement sits on top of an ancient cliff line and geological investigation has shown that the camp probably sits in a small saddle in the landscape between an old sea stack and rising ground to the north.  This situation would have afforded a degree of protection from the weather during a period when the climate was still relatively cold.  This site dates toward the end of the last ice age and was occupied by modern human hunter-gatherers of the Magdalenian culture, who reoccupied northern and western Europe between 16 and 13,000 years ago.  Hunting animals like reindeer and horse, they left a rich record of sophisticated stone age technology and spectacular works of art including the cave paintings at Altamira and Lascaux.

For this reason the team are paying particular attention to three fragments of an exotic stone recovered from the site which show the traces of fine engraved lines across their surface.

Dr Silvia Bello, of the Natural History Museum, who is currently studying the fragments said “We are at an early stage in our investigations, but we can already say the stones are not natural to the site, they show clear incised lines consistent with being made by stone stools, and they do not have any obvious functional role. Engraved works of abstract or figurative art on flat stones are part of the Magdalenian cultural package and one exciting possibility is that this is what we have here.”

The fragments were found within one small corner of the 2015 excavation trenches, alongside stone artefacts and close to a concentration of burnt bone, sealed within an apparent ancient landsurface and associated with possible paving slabs.

The announcement coincides with the opening of Jersey Heritage’s Jersey: Ice Age Island exhibition, displaying the results of the team’s work alongside the wider record of Ice Age archaeology from Jersey, the British Isles and Northern France.

Jon Carter, Director of Jersey Heritage said, “Jersey has an exceptional record of early stone age archaeology for such a small island, and this exhibition show cases these sites and the science behind research currently being undertaken by the Ice Age Island team. This research, supported by the Sates of Jersey Tourism Development Fund and Capco Trust, is bringing to light new stories from Jersey’s deep Ice Age heritage and continuing to show that the Island, with exceptional sites such as Les Varines and La Cotte de St Brelade is a scientific treasure trove”

The finds are the latest results from the Ice Age Island project, a collaboration between Jersey Heritage and a UK archaeological team run, through the British Museum with the UCL Institute of Archaeology, the University of Manchester, University of Wales Trinity St Davids, St Andrews University and the University of Southampton (CAHO).  The project is funded by the Jersey Tourist Development Fund and the Capco Trust, while on-going analysis is supported by the Pathways to Ancient Britain and Human Behaviour in 3D Projects funded by the Calleva Foundation. The Jersey: Ice Age Island Exhibition runs from the 25th October 2015 until 30th December 2016 at Jersey Museum.

A team of researchers has discovered the fossil of a 305-million-year-old arachnid, which will help scientists to understand more about the early origins of modern-day spiders.

The new species, named Idmonarachne brasieri in honour of Professor Martin Brasier, University of Oxford, who passed away in December 2014, was found in Montceau-les-Mines, France, and researchers from The University of Manchester, Berlin's Museum fur Naturkunde, the University of Kansas and Imperial College London have worked with the Natural History Museum and the UK's Diamond Light Source to scan and examine the fossil in detail.

Details of the origins of spiders remain limited, with little knowledge of their predecessors and no insights into character acquisition early in their evolution. This fossil was preserved in 3D, which enabled the researchers to investigate its minute anatomical details.

We have known since 2008 that a group called the uraraneids were a sister group to true spiders -- they could make silk, but probably laid it down in sheets, rather than spinning it as modern spiders do. They also had a tail-like structure at the end called a flagellum.

Analysis of Idmonarachne brasieri suggests that as the spider lineage evolved, the animals lost their tail-like structure, and developed spider-like fangs and limbs. Whilst they could likely make silk, the ancestors lacked the ability to spin it using specialised appendages called spinnerets. These are the features that define true spiders, and give them more control over the use and distribution of silk.

Lead author Russell Garwood, of The University of Manchester's School of Earth, Atmospheric & Environmental Sciences, said, "Our new fossil occupies a key position in the evolution of spiders. It isn't a true spider, but has given us new information regarding the order in which the bits of the anatomy we associate with spiders appeared as the group evolved."

This is part of an ongoing effort to look at early arachnids, and see what this can tell us about the early evolution of the group, how they came onto land and what their evolutionary tree looks like. Arachnids as a whole are a very diverse group, but working out how they are all related to each other has proved a challenge. The authors hope that by better understanding these fossils, they can help fill in some of the blanks.

The discovery is published in the Proceedings of the Royal Society B.

Dazzling treasures combining gold and precious pigments - some of the finest illuminated manuscripts in the world - will go on display on Saturday 30 July in celebration of the Fitzwilliam Museum’s bicentenary.

The majority of the exhibits are from the Museum’s own rich collections, and those from the founding bequest of Viscount Fitzwilliam in 1816 can never leave the building and can only be seen at the Museum. For the first time, the secrets of master illuminators and the sketches hidden beneath the paintings will be revealed in a major exhibition presenting new art historical and scientific research.

Spanning the 8th to the 17th centuries, the 150 manuscripts and fragments in >COLOUR: The Art and Science of Illuminated Manuscripts guide us on a journey through time, stopping at leading artistic centres of medieval and Renaissance Europe. Exhibits highlight the incredible diversity of the Fitzwilliam’s collection: including local treasures, such as the Macclesfield Psalter made in East Anglia c.1330-1340, a leaf with a self-portrait made by the Oxford illuminator William de Brailes c.1230-1250, and a medieval encyclopaedia made in Paris c.1414 for the Duke of Savoy.

Four years of cutting-edge scientific analysis and discoveries made at the Fitzwilliam have traced the creative process from the illuminators’ original ideas through their choice of pigments and painting techniques to the completed masterpieces.

“Leading artists of the Middle Ages and early Renaissance did not think of art and science as opposing disciplines,” says curator, Dr Stella Panayotova, Keeper of Manuscripts and Printed Books. “Instead, drawing on diverse sources of knowledge, they conducted experiments with materials and techniques to create beautiful works that still fascinate us today.”

Merging art and science, COLOUR shares the research of MINIARE (Manuscript Illumination: Non-Invasive Analysis, Research and Expertise), an innovative project based at the Fitzwilliam. Collaborating with scholars from the University of Cambridge and international experts, the Museum’s curators, scientists and conservators have employed pioneering analytical techniques to identify the materials and methods used by illuminators.

“This has been an exciting project,” says research scientist, Dr Paola Ricciardi. “By combining imaging and spectroscopic analysis — methods more commonly associated with remote sensing and analytical chemistry — and by exploring such a diverse range of manuscripts, we can begin to understand how illuminators actually worked.”

“A popular misconception is that all manuscripts were made by monks and contained religious texts, but from the 11th century onwards professional scribes and artists were increasingly involved in a thriving book trade, producing both religious and secular texts. Scientific examination has revealed that illuminators sometimes made use of materials associated with other media, such as egg yolk, which was traditionally used as a binder by panel painters.”

Other discoveries include pigments rarely associated with manuscript illumination – such as the first ever example of smalt detected in a Venetian manuscript. Smalt, obtained by grinding blue glass, was found in a Venetian illumination book made c.1420. Evidently, the artist who painted it had close links with the famed glassmakers of Murano. This example predates by half a century the documented use of smalt in Venetian easel paintings.

Analyses of sketches lying beneath the paint surfaces, and of later additions and changes to paintings help to shed light on manuscripts and their owners. One French prayer book, made c.1430, was adapted over three generations to reflect the personal circumstances and dynastic anxieties of a succession of aristocratic women.

Adam and Eve were originally shown naked in an ABC commissioned c.1505 by the French Queen, Anne of Brittany (1476-1514) for her five-year-old daughter. However, a later owner, offended by the nudity, gave Eve a veil and Adam a skirt. Infrared imaging techniques and mathematical modelling have made it possible to reconstruct the original composition without harming the manuscript.

The Museum’s treasures will be displayed alongside carefully selected loans — celebrated manuscripts from Cambridge libraries as well as other institutions in the UK and overseas. These include an 8th century Gospel Book from Corpus Christi College, the University Library’s famous Life of Edward the Confessor, magnificent Apocalypses from Trinity College and Lambeth Palace, London, and a unique model book from Göttingen University.

Visitors will be encouraged to make their own discoveries in the exhibition galleries and online through a new, free digital resource: >ILLUMINATED: Manuscripts in the Making. With hundreds of high resolution digital images and infrared photographs, this interactive, cross-disciplinary resource offers users in-depth information on the manuscripts’ contents, patrons, cultural and historical contexts, as well as scientific data relating to artists’ techniques and materials.

With over 300 illustrations in full colour, the authoritative exhibition catalogue encompasses subjects as diverse as the trade in pigments, painting techniques, the medieval science of optics and modern-day forgeries. Catalogue entries and essays by leading experts offer readers insight into all aspects of colour from the practical application of pigments to its symbolic meaning.

“We are delighted to be presenting this exhibition in our bicentenary year,” says director, Tim Knox. “Ten years ago The Cambridge Illuminations was the Museum’s first ever record breaking exhibition, attracting over 80,000 visitors. People were enchanted by the remarkable beauty and delicacy of the manuscripts. I am convinced that our bicentenary visitors will again be equally inspired by the superb illuminations collected and treasured at the Fitzwilliam for 200 years, and will value this rare opportunity to find out how they were made and how we are preserving them for the future.”

COLOUR: The Art and Science of Illuminated Manuscripts will run during the second half of the Fitzwilliam’s bicentenary year, from 30 July to 30 December 2016. Admission is free.

While searching through historical archives to find out more about the 15th-century climate of what is now Belgium, northern France, Luxembourg, and the Netherlands, Chantal Camenisch noticed something odd. "I realised that there was something extraordinary going on regarding the climate during the 1430s," says the historian from the University of Bern in Switzerland.

Compared with other decades of the last millennium, many of the 1430s' winters and some springs were extremely cold in the Low Countries, as well as in other parts of Europe. In the winter of 1432-33, people in Scotland had to use fire to melt wine in bottles before drinking it. In central Europe, many rivers and lakes froze over. In the usually mild regions of southern France, northern and central Italy, some winters lasted until April, often with late frosts. This affected food production and food prices in many parts of Europe. "For the people, it meant that they were suffering from hunger, they were sick and many of them died," says Camenisch.

She joined forces with Kathrin Keller, a climate modeller at the Oeschger Centre for Climate Change Research in Bern, and other researchers, to find out more about the 1430s climate and how it impacted societies in northwestern and central Europe. Their results are published in >Climate of the Past, a journal of the European Geosciences Union.

They looked into climate archives, data such as tree rings, ice cores, lake sediments and historical documents, to reconstruct the climate of the time. "The reconstructions show that the climatic conditions during the 1430s were very special. With its very cold winters and normal to warm summers, this decade is a one of a kind in the 400 years of data we were investigating, from 1300 to 1700 CE," says Keller. "What cannot be answered by the reconstructions alone, however, is its origin -- was the anomalous climate forced by external influences, such as volcanism or changes in solar activity, or was it simply the random result of natural variability inherent to the climate system?"

There have been other cold periods in Europe's history. In 1815, the volcano Mount Tambora spewed large quantities of ash and particles into the atmosphere, blocking enough sunlight to significantly reduce temperatures in Europe and other parts of the world. But the 1430s were different, not only in what caused the cooling but also because they hadn't been studied in detail until now.

The climate simulations ran by Keller and her team showed that, while there were some volcanic eruptions and changes in solar activity around that time, these could not explain the climate pattern of the 1430s. The climate models showed instead that these conditions were due to natural variations in the climate system, a combination of natural factors that occurred by chance and meant Europe had very cold winters and normal to warm summers.

Regardless of the underlying causes of the odd climate, the 1430s were "a cruel period" for those who lived through those years, says Camenisch. "Due to this cluster of extremely cold winters with low temperatures lasting until April and May, the growing grain was damaged, as well as the vineyards and other agricultural production. Therefore, there were considerable harvest failures in many places in northwestern and central Europe. These harvest failures led to rising food prices and consequently subsistence crisis and famine.

Furthermore, epidemic diseases raged in many places. Famine and epidemics led to an increase of the mortality rate." In the paper, the authors also mention other impacts: "In the context of the crisis, minorities were blamed for harsh climatic conditions, rising food prices, famine and plague." However, in some cities, such as Basel, Strasbourg, Cologne or London, societies adapted more constructively to the crisis by building communal granaries that made them more resilient to future food shortages.

Keller says another decade of very cold winters could happen again. "However, such temperature variations have to be seen in the context of the state of the climate system. Compared to the 15th century we live in a distinctly warmer world. As a consequence, we are affected by climate extremes in a different way -- cold extremes are less cold, hot extremes are even hotter."

The team says their Climate of the Past study could help people today by showing how societies can be affected by extreme climate conditions, and how they should take precautions to make themselves less vulnerable to them. In the 1430s, people had not been exposed to such extreme conditions before and were unprepared to deal with the consequences.

"Our example of a climate-induced challenge to society shows the need to prepare for extreme climate conditions that might be coming sooner or later," says Camenisch. "It also shows that, to avoid similar or even larger crises to that of the 1430s, societies today need to take measures to avoid dangerous anthropogenic climate interference."

By comparing the genes of current-day North and South Americans with African and European populations, an Oxford University study has found the genetic fingerprints of the slave trade and colonization that shaped migrations to the Americas hundreds of years ago.

The study published in Nature Communications found that:

• While Spaniards provide the majority of European ancestry in continental American Hispanic/Latino populations, the most common European genetic source in African-Americans and Barbadians comes from Great Britain.

• The Basques, a distinct ethnic group spread across current-day Spain and France, provided a small but distinct genetic contribution to current-day Continental South American populations, including the Maya in Mexico.

• The Caribbean Islands of Puerto Rico and the Dominican Republic are genetically similar to each other and distinct from the other populations, probably reflecting a different migration pattern between the Caribbean and mainland America.

• Compared to South Americans, people from Caribbean countries (such as the Barbados) had a larger genetic contribution from Africa.

• The ancestors of current-day Yoruba people from West Africa (one of the largest African ethnic groups) provided the largest contribution of genes from Africa to all current-day American populations.

• The proportion of African ancestry varied across the continent, from virtually zero (in the Maya people from Mexico) to 87% in current-day Barbados.

• South Italy and Sicily also provided a significant European genetic contribution to Colombia and Puerto Rico, in line with the known history of Italian emigrants to the Americas in the late 19th and early 20th century.

• One of the African-American groups from the USA had French ancestry, in agreement with historical French immigration into the colonial Southern United States.

• The proportion of genes from European versus African sources varied greatly from individual to individual within recipient populations.

'We found that the genetic profile of Americans is much more complex than previously thought,' said study leader Professor Cristian Capelli from the Department of Zoology.

The research team analysed DNA samples collected from people in Barbados, Columbia, the Dominican Republic, Ecuador, Mexico, Puerto Rico and African-Americans in the USA.

They used a technique called haplotype-based analysis to compare the pattern of genes in these 'recipient populations' to 'donor populations' in areas where migrants to America came from.

'We firstly grouped subsets of people in Africa and Europe who were genetically similar and used this fine scale resolution to find which combinations of these clusters resulted in the sort of mixtures that we now see in people across the Americas', said the study's first author, Dr Francesco Montinaro from the Department of Zoology.

'We can see the huge genetic impact that the slave trade had on American populations and our data match historical records', said study author Dr Garrett Hellenthal from the UCL Genetics Institute, 'The majority of African Americans have ancestry similar to the Yoruba people in West Africa, confirming that most African slaves came from this region. In areas of the Americas historically under Spanish rule, populations also have ancestry related to what is now Senegal and Gambia. Records show that around a third of the slaves sent to Spanish America in the 17th Century came from this region, and we can see the genetic evidence of this in modern Americans really clearly.'

These genetic findings also uncover previously unknown migration. ‘We found a clear genetic contribution from the Basques in modern-day Maya in Mexico’, said Professor Capelli. ‘This suggests that the Basque also took part in the colonisation of the Americas, coming over either with the Spanish conquistadores or in later waves of migration’.

'The differences in European ancestry between the Caribbean islands and mainland American population that we found were also previously unknown. It is likely that these differences reflect different patterns of migration between the Caribbean and mainland America.'

'These results show just how powerful a genetic approach can be when it comes to uncovering hidden patterns of ancestry. We hope to use the same approach to look at other populations with diverse genetic contributions, such as Brazilians,' said Professor Capelli.

Some of the final results sent back by ESA's Venus Express before it plummeted down through the planet's atmosphere have revealed it to be rippling with atmospheric waves – and, at an average temperature of -157°C, colder than anywhere on Earth.

As well as telling us much about Venus' previously-unexplored polar regions and improving our knowledge of our planetary neighbour, the experiment holds great promise for ESA's ExoMars mission, which is currently winging its way to the Red Planet. The findings were published in the journal Nature Physics.

ESA's Venus Express arrived at Venus in 2006. It spent eight years exploring the planet from orbit, vastly outliving the mission's planned duration of 500 days, before running out of fuel. The probe then began its descent, dipping further and further into Venus' atmosphere, before the mission lost contact with Earth (November 2014) and officially ended (December 2014).

However, Venus Express was industrious to the end; low altitude orbits were carried out during the final months of the mission, taking the spacecraft deep enough to experience measurable drag from the atmosphere. Using its onboard accelerometers, the spacecraft measured the deceleration it experienced as it pushed through the planet's upper atmosphere – something known as aerobraking.

"Aerobraking uses atmospheric drag to slow down a spacecraft, so we were able to use the accelerometer measurements to explore the density of Venus' atmosphere," said Ingo Müller-Wodarg of Imperial College London, UK, lead author of the study. "None of Venus Express' instruments were actually designed to make such in-situ atmosphere observations. We only realised in 2006 – after launch! – that we could use the Venus Express spacecraft as a whole to do more science."

When Müller-Wodarg and colleagues gathered their observations Venus Express was orbiting at an altitude of between 130 and 140 kilometres near Venus' polar regions, in a portion of Venus' atmosphere that had never before been studied in situ.

Previously, our understanding of Venus' polar atmosphere was based on observations gathered by NASA's Pioneer Venus probe in the late 1970s. These were of other parts of Venus' atmosphere, near the equator, but extrapolated to the poles to form a complete atmospheric reference model.

These new measurements, taken as part of the Venus Express Atmospheric Drag Experiment (VExADE) from 24 June to 11 July 2014, have now directly tested this model – and reveal several surprises.

For one, the polar atmosphere is up to 70 degrees colder than expected, with an average temperature of -157°C (114 K). Recent temperature measurements by Venus Express' SPICAV instrument (SPectroscopy for the Investigation of the Characteristics of the Atmosphere of Venus) are in agreement with this finding.

The polar atmosphere is also not as dense as expected; at 130 and 140 km in altitude, it is 22% and 40% less dense than predicted, respectively. When extrapolated upward in the atmosphere, these differences are consistent with those measured previously by VExADE at 180 km, where densities were found to be lower by almost a factor of two.

"This is in-line with our temperature findings, and shows that the existing model paints an overly simplistic picture of Venus' upper atmosphere," added Müller-Wodarg. "These lower densities could be at least partly due to Venus' polar vortices, which are strong wind systems sitting near the planet's poles. Atmospheric winds may be making the density structure both more complicated and more interesting!"

Additionally, the polar region was found to be dominated by strong atmospheric waves, a phenomenon thought to be key in shaping planetary atmospheres – including our own.

"By studying how the atmospheric densities changed and were perturbed over time, we found two different types of wave: Atmospheric gravity waves and planetary waves," explained co-author Sean Bruinsma of the Centre National D'Etudes Spatiales (CNES), France. "These waves are tricky to study, as you need to be within the atmosphere of the planet itself to measure them properly. Observations from afar can only tell us so much."

Atmospheric gravity waves are similar to waves we see in the ocean, or when throwing stones in a pond, only they travel vertically rather than horizontally. They are essentially a ripple in the density of a planetary atmosphere – they travel from lower to higher altitudes and, as density decreases with altitude, become stronger as they rise. The second type, planetary waves, are associated with a planet's spin as it turns on its axis; these are larger-scale waves with periods of several days.

We experience both types on Earth. Atmospheric gravity waves interfere with weather and cause turbulence, while planetary waves can affect entire weather and pressure systems. Both are known to transfer energy and momentum from one region to another, and so are likely to be hugely influential in shaping the characteristics of a planetary atmosphere.

"We found atmospheric gravity waves to be dominant in Venus' polar atmosphere," added Bruinsma. "Venus Express experienced them as a kind of turbulence, a bit like the vibrations you feel when an aeroplane flies through a rough patch. If we flew through Venus' atmosphere at those heights we wouldn't feel them because the atmosphere just isn't dense enough, but Venus Express' instruments were sensitive enough to detect them."

Venus Express found atmospheric waves at an altitude of 130-140 km that the team think originated from the upper cloud layer in Venus' atmosphere, which sits at and below altitudes of approximately 90 km, and a planetary wave that oscillated with a period of five days. "We checked carefully to ensure that the waves weren't an artefact of our processing," said co-author Jean-Charles Marty, also of CNES.

This is not just a first for Venus Express; while the aerobraking technique has been used for Earth satellites, and was previously used on NASA-led missions to Mars and Venus, it had never before been used on any ESA planetary mission.

However, ESA's ExoMars Trace Gas Orbiter, which launched earlier this year, will use a similar technique. "During this activity we will extract similar data about Mars' atmosphere as we did at Venus," added Håkan Svedhem, project scientist for ESA's ExoMars 2016 and Venus Express missions.

"For Mars, the aerobraking phase would last longer than on Venus, for about a year, so we'd get a full dataset of Mars' atmospheric densities and how they vary with season and distance from the Sun," added Svedhem. "This information isn't just relevant to scientists; it's crucial for engineering purposes as well. The Venus study was a highly successful test of a technique that could now be applied to Mars on a larger scale – and to future missions after that."

A single entry of the plague bacterium into Europe was responsible for the Black Plague of the mid-14th century. This same strain sparked recurrent outbreaks on the continent over the following four centuries before spreading to China, where it triggered the third plague pandemic in the late 19th century. The wave of plague that traveled to Asia later became the source population for modern-day epidemics around the globe. The bacterium's routes over time were revealed by genome analyses published in >Cell Host & Microbe.

"Our study is the first to provide genetic support for plague's travel from Europe into Asia after the Black Death, and it establishes a link between the Black Death in the mid-14th century and modern plague," says first author Maria Spyrou of the Max Planck Institute for the Science of Human History.

The plague bacterium, Yersinia pestis, is one of the deadliest pathogens in human history, sparking three major pandemics: the Plague of Justinian, which struck the Roman Empire during the 6th and 8th centuries; the second plague pandemic, which first erupted in Europe in the mid-14th-century Black Death and continued to strike the continent in recurrent outbreaks until the mid-18th century; and the third plague pandemic, which emerged in China during the late 19th century.

Evidence based on ancient DNA samples and historical climate patterns has suggested that the recurrent outbreaks of the second pandemic were caused by multiple reintroductions of Yersinia pestis into Europe, most likely from Asia. Moreover, some scientists have recently suggested that the plague bacterium migrated from Europe to Asia after the Black Death, later giving rise to the third pandemic. But until now, genomic evidence to support this model was missing.

To shed light on the origin and path of the second pandemic, Spyrou and co-senior study authors Alexander Herbig, Kirsten Bos, and Johannes Krause of the Max Planck Institute for the Science of Human History collected samples from plague-infected individuals buried in mass grave sites in Barcelona, Spain, and Ellwangen, Germany, as well as a single grave in Bolgar City, Russia.

"The mass burials where our samples come from often represent events where hundreds of people died of plague during a single outbreak," Herbig says. "This gives us an impression about how significant the impact of this disease was during medieval times."

The Bolgar City site was dated to the second half of the 14th century using coin artifacts known to have been minted after 1362. Radiocarbon dates from bone fragments and tooth roots were estimated at 1300-1420 for Barcelona, 1298-1388 for Bolgar City, and 1486-1627 for Ellwangen.

After analyzing DNA extracts from the teeth of 178 individuals, the researchers identified Y. pestis DNA in extracts from 32 individuals. Three individuals from Barcelona, Bolgar City, and Ellwangen had sufficient Y. pestis DNA for genome-level analysis. The researchers sequenced the genomes of these three ancient Y. pestis strains and compared them to 148 previously sequenced ancient and modern strains to reconstruct the Y. pestis phylogenetic tree.

The phylogenetic analysis revealed no differences between their Black Death strain from Barcelona and previously genotyped strains from mid-14th-century London. The simultaneous presence of the same strain in both southern and northern Europe suggests that Y. pestis entered the continent in a single wave rather than through multiple pulses during the Black Death.

These Black Death strains from London and Barcelona gave rise to a branch containing the Ellwangen strain and previously sequenced 18th-century strains from the Great Plague of Marseille in France. Moreover, all three newly reconstructed genomes and previously sequenced genomes from the second plague grouped together in the same branch on the phylogenetic tree. Taken together, these findings suggest that a single Y. pestis lineage was responsible for the Black Death and subsequent second pandemic outbreaks throughout Europe.

Meanwhile, the Bolgar City strain shared similarities with the Black Death London strain as well as all modern strains. This finding supports the idea that one Y. pestis lineage traveled from Europe to Asia after the Black Death, later sparking the third pandemic and modern-day epidemics worldwide.

"Our most significant finding revealed a link between the Black Death and modern plague," Krause says. "Though several plague lineages exist in China today, only the lineage that caused the Black Death several centuries earlier left Southeast Asia in the late 19th century pandemic and rapidly achieved a near worldwide distribution."

In future studies, the researchers plan to gain additional insights into the entry and end points of the Black Death in Europe. They hope to expand their sample range and explore these regions further to better understand the route traveled by the disease, the evolutionary changes it acquired at different stages, and the toll it had on the human population.

"We hope that our findings will highlight the importance for more extensive sampling and sequencing of both ancient and modern plague isolates around the world, and open up new research themes regarding the role played by Europe and West Asia in plague's evolution and ecology," Bos says.

A research team led by scientists of the Max Planck Institute for Evolutionary Anthropology scanned the skulls of Neandertals and found the small middle ear ossicles, which are important for hearing, still preserved within the cavities of the ear. To their surprise, the Neandertal ossicles are morphologically distinct from the ossicles of modern humans. Despite the differences in morphology, the function of the middle ear is largely the same in the two human species.

The authors relate the morphological differences in the ossicles to different evolutionary trajectories in brain size increase and suggest that these findings might be indicative of consistent aspects of vocal communication in modern humans and Neandertals. These findings are also of importance for shedding light on the emergence of human spoken language, which can only be inferred indirectly from the archaeological and fossil record.

The three bones of the middle ear (hammer, anvil, stapes) make up the ossicular chain. This bony chain, which is found in all mammals is dedicated to the transmission of sound waves from the tympanic membrane to the inner ear and helps in amplifying the energy of airborne sound in order to allow the sound wave to travel within the fluid-filled inner ear.

Moreover, the ear ossicles are not only important for correct hearing but are also the smallest bones of our body. Thus, it does not surprise that the ossicles are among the most rarely found bones in the mammalian fossil record including the one of human ancestors. Given their important role in audition this lack of knowledge has ever been frustrating for researchers interested in studying hearing capacities of extinct species.

Tiny bones still present

This also applies to our closest extinct relatives - the Neandertals whose communicative capacities including existence of human spoken language is a major scientific debate ever since the first discovery of Neandertal remains. A research team led by Alexander Stoessel from the Max Planck Institute for Evolutionary Anthropology in Leipzig used high-resolution computer tomography scans of Neandertal skulls and systematically checked for ossicles that potentially became trapped within the cavity of the middle ear.

And indeed, the researchers found ear ossicles in 14 Neandertal individuals coming from sites in France, Germany, Croatia and Israel, resulting in the largest sample of ear ossicles of any fossil human species. “We were really astonished how often the ear ossicles are actually present in these fossil remains, particularly when the ear became filled with sediments” says lead researcher Alexander Stoessel.

After virtually reconstructing the bones, the team - which also included scientist from the Friedrich-Schiller University in Jena and the University College in London – compared them to ossicles of anatomically modern humans and also chimpanzees and gorillas which are our closest living relatives.

Since ossicles are not only small but also complex-shaped the researchers compared them by means of three-dimensional analysis that uses a much larger number of measuring points allowing for examination of the three-dimensional shape of a structure. “Despite the close relationship between anatomically modern humans and Neandertals to our surprise the ear ossicles are very differently shaped between the two human species” says Romain David who was involved in the study.

Based on the results of the morphological comparison the research team examined the potential reasons for these different morphologies. In order to see if these differences may affect hearing capacity of Neandertals and modern humans or reflects a tight relationship with the base of the skull they also analyzed the structures surrounding the ear ossicles. The outcome of this analysis was surprising, again since the functional parameters of the Neandertal and modern human middle ear are largely similar despite contrasting morphologies.

Similar communication skills in archaic humans

Instead, the team found the ear ossicles strongly related to the morphology of the surrounding cranial structures which also differ between the two human groups. The reseachers attribute these differences to different evolutionary trajectories that Neandertals and modern humans pursued in order to increase their brain volume which also impacted the structures of the cranial base which the middle ear is a part of.

“For us these results could be indicative for consistent aspects of vocal communication in anatomically modern humans and Neandertals that were already present in their common ancestor” says Jean-Jacques Hublin who is an author of this study and continues “these findings should be a basis for continuing research on the nature of the spoken language in archaic hominins”.

The findings are published in >Proceedings of the National Academy of Sciences.

3D reconstructions of some of Syria's most spectacular archaeological sites go online Tuesday after a big push to digitalise the war-torn country's threatened heritage.

French digital surveyors have been working with Syrian archaeologists to map some of the country's most famous monuments after Islamic State jihadists sparked international outrage by blowing up two temples in the UNESCO World Heritage Site of Palmyra last year.

The eighth-century Umayyad Mosque in the capital Damascus—regarded by some as the fourth holiest place in Islam—and the Krak des Chevaliers Crusader castle near the ravaged city of Homs are the two most famous buildings to have been scanned in minute detail.

Photogrammetric technology developed by the French start-up Iconem has also been used to record the Roman theatre in the coastal city of Jableh and the Phoenician site in the ancient port of Ugarit, where evidence of the world's oldest alphabet was found.

Its technicians have also been working alongside 15 specialists from the Syrian Directorate General of Antiquities and Museums (DGAM) to digitalise some of the country's major museum collections.

Hundreds of important heritage sites have been sacked or destroyed during the five-year conflict, with the destruction of the first-century temples of Bel and Baalshamin in the ancient desert city of Palmyra causing a global outcry.

The Islamic State group has made a point of razing ancient shrines and statues it considers as idolatry and is also suspected of involvement in the illegal sale of antiquities.

Work on the "Syrian Heritage" database, the biggest 3D record of the country's monuments and treasures, began in December and includes a large number of Ottoman-era buildings in Damascus as well as its 11th-century citadel, which looms over the city.

The head of DGAM, Maamoun Abdulkarim, said the operation was essential to "avoid an irreplacable loss to humanity" given "the dramatic situation in our country".

"This solution gives our archaeological sites a real hope of renaissance and allows the memory of them to be preserved, no matter what happens," he added in a statement.

The drive, carried out with the help of the French grande ecole ENS and the research institute INRIA, is one of a number trying to catalogue sites in danger of falling into the line of fire.

The Institute for Digital Archaeology, created by Oxford and Harvard universities and Dubai's Museum of the Future, is also compiling a record of many vulnerable sites in Syria and neighbouring Iraq.

It has handed out 5,000 low-cost 3D cameras to archaeologists and NGOs with the hope of gathering a million images of threatened sites.

The Million Images Database hopes be fully online by the end of the year and will display life-size replicas of Palmyra's destroyed triumphal arch in New York's Times Square and London's Trafalgar Square in April.

The replicas of the arch, blown up by IS jihadists in October, are being made with the world's largest 3D printer.

France's culture minister had earlier floated the idea of a 3D recreation of the ancient city, known as the "Pearl of the Desert", based on photos taken by tourists over the years.

A "unique" Roman headstone is the first of its kind unearthed in the UK, experts believe. The tombstone was found near skeletal remains thought to belong to the person named on its inscription, making the discovery unique.

Archaeologists behind the dig in Cirencester, Gloucestershire, said they believed it marked the grave of a 27-year-old woman called Bodica. The bodies of three children were also found in the "family burial plot".

Neil Holbrook, of Cotswold Archaeology, translated the Roman inscription on the tombstone, which reads: "To the spirit of the departed Bodica [or Bodicaca], wife, lived for 27 years."

Mr Holbrook said: "The unique aspect is that you can put a name to the person who lies beneath the tombstone."

"What's weird is that the inscription only fills half of the panel, so there's a space left below it. You can see horizontal marking-out lines, so I guess what they were going to do was come back later when her husband died and add his name to the inscription," Mr Holbrook added.

He added that the skeletal remains, including the skull, were being excavated from beneath the headstone.

Mr Holbrook has suggested the name Bodica was of Celtic origin. "Perhaps Bodica is a local Gloucestershire girl who's married an incoming Roman or Gaul from France and has adopted this very Roman way of death," he said.

He said making the "good quality" headstone must have cost "quite a lot of money" at the time.

The headstone's detailed carved pediment - or triangular top section - was particularly interesting, he said.

"Looking at the pediment, those little 'teeth' which we could see from the back are decorative swirls. It looks like a draping of a cloth or sheet, so in many ways the decoration is really fine."

About 300 to 400 Roman tombstones have been discovered in the UK, with the tombstone being the tenth found in Cirencester.

The stone, which is made of Cotswold limestone, was partially cleaned up on-site by the team, but will be taken away for further inspection.

Mr Holbrook said it was "amazing" the tombstone had survived.

"When they built the garage in the 1960s they scraped across the top of the stone to put a beam in. If they'd gone a couple of inches lower they'd have smashed it to smithereens."

Roman tombstones were often taken away and smashed up to be re-used in buildings in Cirencester in the Medieval period.

"This stone might have fallen over quite quickly, and was covered over, and that's why it escaped the stone robbers," Mr Holbrook said.

A total of 55 Roman graves have been found during the dig at St James Place. A further 70 graves were discovered on the same site of the former Bridges Garage on Tetbury Road and a bronze cockerel figurine was found in 2011.

Cirencester, or Corinium as it was known, was the largest town in Roman Britain after London.

Opening April 27 (and running until July 24, 2016) at New York’s Metropolitan Museum of Art, the landmark international loan exhibition Court and Cosmos: The Great Age of the Seljuqs features spectacular works of art created in the 11th through 13th century from Turkmenistan to the Mediterranean.

One of the most productive periods in the history of the region from Iran to Anatolia (in modern Turkey) corresponds to the rule of the Seljuqs and their immediate successors, from 1038 to 1307.

The Seljuqs were a Turkic dynasty of Central Asian nomadic origin that established a vast, but decentralized and relatively short-lived, empire in West Asia (present-day Turkmenistan, Iran, Iraq, Syria, and Turkey).

Under Seljuq rule, the exchange and synthesis of diverse traditions—including Turkmen, Perso-Arabo-Islamic, Byzantine, Armenian, Crusader, and other Christian cultures—accompanied economic prosperity, advances in science and technology, and a great flowering of culture within the realm.

Approximately 270 objects—including ceramics, glass, stucco, works on paper, woodwork, textiles, and metalwork—from American, European, and Middle Eastern public and private collections are shown. Many of the institutions have never lent works from their collections before. Among the highlights are a dozen important loans from Turkmenistan—the exhibition marks the first time that Turkmenistan as an independent country has permitted an extended loan of a group of historical objects to a museum in the United States.

Under the Great Seljuqs of Iran, the middle class prospered, spurring arts patronage, technological advancements, and a market for luxury goods. In contrast, in Anatolia, Syria, and the Jazira (northwestern Iraq, northeastern Syria, and southeastern Turkey)—which were controlled by the Seljuq successor dynasties (Rum Seljuqs, Artuqids, and Zangids)—art was produced under royal patronage, and Islamic iconography was introduced to a predominantly Christian area.

Furthermore, a number of artists had immigrated to the region from Iran in response to the Mongol conquest in 1220. Because patrons, consumers, and artists came from diverse cultural, religious, and artistic backgrounds, distinctive arts were produced and flourished in the western parts of the Seljuq realm.

Exhibition Overview

Arranged thematically, the exhibition opens with a display of artifacts that name the Seljuq sultans and members of the ruling elite. In Central Asia and Iran, inscriptions appeared on coins and architecture. Stucco reliefs representing royal guards, amirs, and courtiers serve to evoke the courts of the Great Seljuq rulers whose names did not appear on objects.

In Anatolia, Syria, and the Jazira, names of Seljuq successor rulers and images appeared on a range of objects. Here, the famous 12th-century cloisonné dish bearing the name of Rukn al-Dawla Dawud, a leader of the Artuqids, is featured.

In the second section, the courtly environment and activities associated with the sultans and their courtiers appear on stucco reliefs, ceramics, metalwork, and other media. While depictions of the Seljuq elite on these works were not intended as actual portraits, the distinctive Central Asian facial type was a standard of beauty under Seljuq rule.

The earliest extant manuscript of the Shahnama (Book of Kings)—the Persian national epic—created in Anatolia in 1217 is a highlight of this section. Additionally, the remarkable Blacas ewer, with its myriad details of life connected to the court, is prominently exhibited.

The three centuries under Seljuq rule were also a period of inventions; and the many advances in science, medicine, and technology were reflected in the manuscripts, scientific instruments, and medical implements of the time. Pages from the early 13th-century illustrated manuscript The Book of Knowledge of Ingenious Mechanical Devices feature some of the fanciful inventions of the Muslim polymath and creative genius Ibn al-Razzaz al-Jazari, whose inventions ranged from clocks and water wheels to automata (robots).

Also noteworthy is an early Islamic astrolabe. (Among the many things that could be determined by means of this complex navigational instrument was the direction of Mecca, and hence the direction of prayer.) Also on view is an intricate pharmacy box with separate compartments for musk, camphor, and other ingredients typical of the medieval pharmacopoeia.

Seljuq art abounds with depictions of real, mythological, and hybrid animals on objects large and small. Animal combat was a favorite theme in Iranian art. The double-headed eagle was adopted as the standard of the Seljuq successor states in Anatolia and the Jazira. Harpies (composite creatures having the body of a bird and the face of a human) and sphinxes (beasts with the body of a lion, face of a human, and occasionally the wings of a bird) appear frequently.

The exquisite Vaso Vescovali—a lidded bowl engraved and inlaid with silver and decorated with complex astrological imagery—features eight personifications of planets on the lid along with the 12 signs of the zodiac and their associated planets on the base, within a profusion of other ornamentation.

The Seljuqs actively promoted Sunni Islam throughout their territory, building madrasas and mosques, and sponsoring the production of Qur’ans and other religious texts. A number of rare and beautifully ornamented examples of the book arts from the time of the Seljuqs are on view. In Syria, the Jazira, and Anatolia—where the majority of the local population, including some of the ruling elite, was Christian—artifacts bearing Christian iconography continued to be made. And a ritual vessel from Georgia, with a Hebrew inscription, attests to the presence of Jewish populations as well. The same artists often served various religious communities. Hence, the styles and artistic traditions of one group merged with those of another.

The sixth and final section of the exhibition focuses on the funerary arts. A variety of tomb markers, cenotaphs, funerary furniture, and patterned textiles discovered in Seljuq tombs are shown. In a proper Muslim burial, the deceased is wrapped in two or three sheets of plain white cloth; the presence of expensive textiles in a funerary context indicates that popular customs and official practice differed significantly.

The exhibition is made possible by the NoRuz at The Met Fund and the Iranian-American Community.

With scientists forecasting sea levels to rise by anywhere from several inches to several feet by 2100, historic structures and coastal heritage sites around the world are under threat. Some sites and artifacts could become submerged.

Scientists, historic preservationists, architects and public officials are meeting this week in Newport, Rhode Island—one of the threatened areas—to discuss the problem, how to adapt to rising seas and preserve historic structures.

"Any coastal town that has significant historic properties is going to be facing the challenge of protecting those properties from increased water and storm activity," said Margot Nishimura, of the Newport Restoration Foundation, the nonprofit group hosting the conference.

Federal authorities have encouraged people to elevate structures in low-lying areas, but that poses challenges in dense neighborhoods of centuries-old homes built around central brick chimneys, Nishimura said, especially ones where preservationists are trying to keep the character intact.

Many of the most threatened sites in North America lie along the East Coast between Cape Hatteras, North Carolina, and southern Maine, where the rate of sea level rise is among the fastest in the world, said Adam Markham, of the Union of Concerned Scientists, a speaker at the conference.

"We're actually not going to be able to save everything," he said.

A look at some of the historic areas and cultural sites that are under threat from rising sea levels:

Statue of Liberty and Ellis Island

Situated in New York Harbor, the Statue of Liberty and Ellis Island are some of New York's most important tourist attractions.

In 2012, Superstorm Sandy submerged most of the low-elevation Liberty and Ellis islands. After the storm, the Statue of Liberty, a gift from the people of France in 1886, was closed for eight months. Ellis Island, the entry point for about 12 million immigrants to the United States from 1892 to 1954, remained closed for nearly a year.

A report by the National Park Service looked at how several parks would be threatened by 1 meter, or around 3 feet, of sea level rise. It found $1.51 billion worth of assets at the Statue of Liberty National Monument were highly exposed to sea level rise.

Much of historic Boston is along the water and is at risk due to sea level rise, including Faneuil Hall, the market building known as the "Cradle of Liberty," and parts of the Freedom Trail, a walking trail that links historic sites around the city.

Boston has seen a growing number of flooding events in recent years, up from two annually in the 1970s to an average of 11 annually between 2009 and 2013, according to a 2014 report by the Union of Concerned Scientists. If sea levels rise by 5 inches, the group reported, the number of floods is projected to grow to 31 annually. If seas rise by 11 inches, the number of flooding events is projected to rise to 72 per year.

Newport

The Point neighborhood in the Rhode Island resort town has one of the highest concentrations of Colonial houses in the United States, and it sits 4 feet above mean sea level. Tidal flooding is already occurring in the neighborhood, and that is expected to increase as sea levels rise, Nishimura said. The smell of sea water already permeates the basement of some homes.

Annapolis

Maryland's capital, on Chesapeake Bay, boasts the nation's largest concentration of 18th-century brick buildings. The city briefly served as the nation's capital in the post-Revolutionary War period, and the Treaty of Paris, which formally ended the war, was ratified there. The city is also home to the U.S. Naval Academy.

The city already sees tidal flooding dozens of times a year, and scientists have predicted number could rise to hundreds annually in the next 30 years.

Jamestown

Established in 1607, it is the first permanent English colony in North America. It sits along the tidal James River in Virginia, and most of the settlement is less than 3 feet above sea level. A large part of the settlement has already eroded because of wave action, Markham said. Storms have also damaged the site, including Hurricane Isabel in 2003, which flooded nearly 1 million artifacts. A rising water table at the site also poses a threat to archaeological remains, Markham said.

He called the loss of archaeological artifacts "an urgent problem" along the U.S. coastline.

Hawaii

Reports by the National Park Service and others have found that rising sea level rises threaten archaeological sites at various historic places in Hawaii. Those include ancient fish ponds at Pu'ukohola Heiau National Historic Site and a "Great Wall" at a sacred site in Pu'uhonua o Honaunau National Historical Park. It is considered the best-preserved such wall in Hawaii.

International Sites

Dozens of UNESCO World Heritage Sites are under threat from sea level rise, according to a 2014 report by climate scientists Ben Marzeion, of the University of Innsbruck in Austria, and Anders Levermann, of the Potsdam Institute in Germany.

Among those are: the Tower of London; Robben Island in South Africa, where Nelson Mandela was imprisoned for 27 years; Venice, Italy, and its lagoon; Mont-Saint-Michel, home to an abbey built atop a rocky islet in France; the Kasbah of Algiers, Algeria; the historic district of Old Quebec, Canada; Old Havana in Cuba; and archaeological areas of Pompeii, Italy, and Carthage in Tunisia.

The authors wrote that their findings indicate that "fundamental decisions with regard to mankind's cultural heritage are required."

New research led by the University of Southampton shows Neanderthals kept coming back to a coastal cave site in Jersey from at least 180,000 years ago until around 40,000 years ago.

As part of a re-examination of La Cotte de St Brelade and its surrounding landscape, archaeologists from Southampton, together with experts from three other universities and the British Museum, have taken a fresh look at artefacts and mammoth bones originally excavated from within the site's granite cliffs in the 1970s. Their findings are published in the >journal Antiquity.

The researchers matched types of stone raw material used to make tools to detailed mapping of the geology of the sea bed, and studied in detail how they were made, carried and modified. This helped reconstruct a picture of what resources were available to Neanderthals over tens of thousands of years -- and where they were travelling from.

Lead author Dr Andy Shaw of the Centre for the Archaeology of Human Origins (CAHO) at the University of Southampton said: "La Cotte seems to have been a special place for Neanderthals. They kept making deliberate journeys to reach the site over many, many generations. We can use the stone tools they left behind to map how they were moving through landscapes, which are now beneath the English Channel. 180,000 years ago, as ice caps expanded and temperatures plummeted, they would have been exploiting a huge offshore area, inaccessible to us today."

Previous research focussed on particular levels in the site where mammoth bones are concentrated, but this new study took a longer-term perspective, looking at how Neanderthals used it and explored the surrounding landscape for over 100,000 years.

The team, including academics from the British Museum, University College London (UCL) and the University of Wales found that Neanderthals kept coming back to this particular place, despite globally significant changes in climate and landscape. During glacial phases (Ice Ages), they travelled to the site over cold, open landscapes, now submerged under the sea. They kept visiting as the climate warmed up and Jersey became a striking highpoint in a wide coastal plain connected to France.

Dr Beccy Scott of the British Museum added: "We're really interested in how this site became 'persistent' in the minds of early Neanderthals. You can almost see hints of early mapping in the way they are travelling to it again and again, or certainly an understanding of their geography. But specifically what drew them to Jersey so often is harder to tease out. It might have been that the whole Island was highly visible from a long way off -- like a waymarker -- or people might have remembered that shelter could be found there, and passed that knowledge on."

Paper author Dr Matt Pope, of the Institute of Archaeology at UCL, agrees: "La Cotte de St Brelade is probably the most important Neanderthal site in northern Europe and could be one of the last known places that Neanderthals survived in the region. It was certainly as important to them as it is to us, as we try and understand how they thrived and survived for 200,000 years.

"With new technology we have been able to reconstruct the environment of the La Cotte Neanderthals in a way earlier researchers couldn't. Our project has really put the Neanderthal back into the landscape, but emphasised how significant the changes in climate and landscape have been since then."

Project leader Professor Clive Gamble, of CAHO at the University of Southampton, comments: "Jersey is an island that endures, summed up by the granite cliffs of St Brelade's Bay. The elements which led to Neanderthals coming back for so many thousands of years shows how this persistence is deep rooted in Jersey's past. Our project has shown that more unites the past with the present than separates. We are not the only humans to have coped successfully with major environmental changes. Let's hope we are not the last."

The team's work was undertaken as part of the 'Crossing the Threshold' project led by Professor Clive Gamble and Dr John McNabb at the University of Southampton, together with UCL and the British Museum. The research was funded by the Arts and Humanities Research Council and looks at major changes in how early humans used places from 400,000 years ago.

'Celts: art and identity' opens at the British Museum on 24 September and will draw on the latest research from Britain, Ireland and Western Europe. The exhibition will tell the story of the different peoples who have used or been given the name ‘Celts’ through the stunning art objects that they made, including intricately decorated jewellery, highly stylised objects of religious devotion, and the decorative arts of the late 19th century which were inspired by the past. The exhibition will then open at the National Museum Scotland in March 2016. As part of the National Programme activity around the Celts exhibition, the British Museum and National Museums Scotland will showcase two rare Iron Age mirrors as a Spotlight tour to partner museums across the UK.

Today the word ‘Celtic’ is associated with the distinctive cultures, languages, music and traditions of Scotland, Ireland, Wales, Cornwall, Brittany and the Isle of Man. Yet the name Celts was first recorded thousands of years earlier, around 500 BC, when the ancient Greeks used it to refer to peoples living across a broad swathe of Europe north of the Alps. The Greeks saw these outsiders as barbarians, far removed from the civilised world of the Mediterranean. They left no written records of their own, but today archaeology is revealing new insights into how they lived. Modern research suggests that these were disparate groups rather than a single people, linked by their unique stylised art. This set them apart from the classical world, but their technological accomplishments stand on a par with the finest achievements of Greek and Roman artists.

A stunning example in the exhibition, from National Museums Scotland, is a hoard of gold torcs found at Blair Drummond in Stirling in 2009 by a metal detectorist on his very first outing. Excavations showed they had been buried inside a timber building, probably a shrine, in an isolated, wet location. These four torcs made between 300–100 BC show widespread connections across Iron Age Europe. Two are made from spiralling gold ribbons, a style characteristic of Scotland and Ireland. Another is a style found in south-western France although analysis of the Blair Drummond gold suggests it was made locally based on French styles. The final torc is a mixture of Iron Age details with embellishments on the terminals typical of Mediterranean workshops. It shows technological skill, a familiarity with exotic styles, and connections to a craftworker or workshop with the expertise to make such an object. The Blair Drummond find brings together the local and the highly exotic in one hoard.

Although Britain and Ireland were never explicitly referred to as Celtic by the Greeks and Romans, some 2,000 years ago these islands were part of a world of related art, values, languages and beliefs which stretched from the Atlantic to the Black Sea. During the Roman period and after the fall of the Western Roman Empire, communities in Ireland and northern and western Britain developed distinct identities. The art and objects which they made expressed first their difference to the Romans, but later the new realities of living in a conquered land or on the edges of the Roman world. These communities were among the first in Britain to become Christian, and missionaries from the north and west helped to convert the pagan Anglo-Saxons.

The exhibition will include iron hand-bells used to call the faithful to prayer, elaborately illustrated gospel books telling the story of Jesus’s life, and beautifully carved stone crosses that stood as beacons of belief in the landscape. An exceptionally rare gilded bronze processional cross from Tully Lough, Ireland (AD 700-800), will be displayed in Britain for the first time. Used during ceremonies and as a mobile symbol of Christianity, the design of this hand-held cross may have inspired some stone crosses, but metal examples rarely survive. Its decorative plates show the wider artistic connections of its makers: three-legged swirls and crescent shapes owe much to earlier Celtic traditions; other geometric motifs echo Roman designs, while interlace designs were popular across Europe and probably inspired by Anglo-Saxon art.

The name Celts had fallen out of use after the Roman period, but it was rediscovered during the Renaissance. From the sixteenth century it became increasingly used as shorthand for the pre-Roman peoples of Western Europe. In the early 1700s, the languages of Scotland, Ireland, Wales, Cornwall, Brittany and the Isle of Man were given the name ‘Celtic’, based on the name used by the Greeks and Romans 2000 years before. In the context of a continually shifting political and religious landscape, ‘Celtic’ acquired a new significance as the peoples of these Atlantic regions sought to affirm their difference and independence from their French and English neighbours, drawing on long histories of distinctive local identities. First used by the ancient Greeks as a way to label outsiders, the word ‘Celtic’ was now proudly embraced to express a sense of shared ancestry and heritage.

Over the following centuries, the Celtic revival movement led to the creation of a re-imagined, romanticised Celtic past, expressed in art and literature such as the painting ‘The Druids: Bringing in the Mistletoe’ by George Henry and Edward Atkinson Hornel, 1890. Druids emerge from a grove of oaks where they have been ceremonially gathering mistletoe in this romantic Victorian reimagining of a scene described by Roman author Pliny the Elder. In an attempt to evoke an authentic Scottish past, the artists incorporated things that they thought of as Celtic: spiral motifs, the brilliant colours of illuminated manuscripts and a snake design inspired by Pictish stones. The painters claimed the faces were based on ancient ‘druid’ skulls. But the features of the central druid were really inspired by photographs of Native Americans.

Today, the word Celtic continues to have a powerful resonance. It calls to mind the ever shifting relationships between the different nations that make up Britain and Ireland, and their diaspora communities around the world. The idea of the Celts also confronts us with the long history of interaction between Britain and the rest of Europe.

Neil MacGregor, Director of the British Museum said “the word Celtic brings together a series of moments across the history of western Europe when particular communities made art and objects that reflect a different, non-Mediterranean, way of thinking about the world. New research is challenging our preconception of the Celts as a single people, revealing the complex story of how this name has been used and appropriated over the last 2,500 years. While the Celts are not a distinct race or genetic group that can be traced through time, the word ‘Celtic’ still resonates powerfully today, all the more so because it has been continually redefined to echo contemporary concerns over politics, religion and identity.”

Gordon Rintoul, National Museums Scotland Director said “Encompassing the latest research from across Europe the exhibition explores the history of the peoples who became known as Celts and examines the powerful objects created and used by them. I am delighted that this collaboration with the British Museum has allowed us to present a stronger, more rounded exhibition than either of the institutions could have achieved on their own. I am sure that audiences in Edinburgh and London will find much to engage, enthuse and inspire them.”

Archaeologists from University of Leicester Archaeological Services (ULAS) have recently excavated a Late Roman cemetery at Western Road in Leicester’s West End. Amongst the 83 skeletons recorded by the team, one burial is proving to be very exciting.

The simple grave in question had been dug into mudstone on the west bank of the River Soar, to the south-west of the Roman town close to the important road known as the Fosse Way. Buried in the grave was the remains of a middle-aged man wearing an elaborately decorated belt in a style that would have been worn by a Late Roman soldier or civil servant during the second half of the 4th century or the early 5th century AD.

The find, which is rare in Britain, was positioned at the waist of the skeleton and comprises a belt buckle, belt plate and strap end.

Nick Cooper, Post-Excavation Manager at ULAS, said: “The survival of the delicate thin sheet bronze belt plate is remarkable. It is cast in the so-called ‘chip-carved’ style decorated with interlocking spirals and would have been riveted to a wide leather belt or girdle with a thinner securing strap running through the buckle and ending with the strap end.”

The buckle is decorated with dolphin heads and the strap end is decorated with crouching dogs on either side of its tapered end.

Parallels for this belt set have been found in other Late Roman cemeteries, for example in London, Dorchester on Thames and Winchester, and at the shore fort on the opposite side of the English Channel at Oudenburg in Belgium.

Research shows that these belts were worn across north-eastern France, Belgium, and along the eastern frontier of the Roman Empire, running along the Rivers Rhine and Danube, where soldiers were stationed. There is some contemporary pictorial evidence to suggest that this type, specifically, was worn by members of the Late Roman military and civilian elite and that the belts were important symbols of authority.

The recent discovery at Western Road is the first occurrence of such a complex belt set in Roman Leicester. The belt’s owner was aged between 36 and 45 when he died. He had survived poor health in childhood to lead a comparatively fit adult life but at some point he had fractured his left forearm; an injury that had healed well but left his wrist weakened. This type of injury is known as a ‘parry fracture’ and is typically caused by raising the arm to ward off a blow or a falling object. The man had also damaged muscles in his upper right arm and shoulder. Such injuries could possibly be caused by over-use, overextending the muscles with movements such as throwing and lifting. Whilst it is difficult to identify exactly what caused these injuries, they are consistent with those a soldier might suffer and reinforce the theory that this man was either a member of the late Roman army or, perhaps following retirement, became an important local civil servant.

The project is funded by Jamie Lewis Residential as part of the site’s redevelopment. Excavation and analysis of the skeletal assemblage has been carried out by a multi-disciplinary team of researchers from University of Leicester Archaeological Services (ULAS), York Osteoarchaeology Ltd., the Scottish Universities Environmental Research Centre (SUERC) and the British Geological Survey (BGS). The belt has been conserved by Graham Morgan.

The belt buckle and other finds from the excavation will be on display on Sunday 10 July at ‘Bringing Our Past To Life’, an exciting family friendly heritage day at Jewry Wall Museum, Leicester (11am-4pm).

Research published in the American Geophysical Union's journal >Global Biogeochemical Cycles shows that recent rises in levels of methane in our atmosphere is being driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.

Atmospheric methane is a major greenhouse gas that traps heat in our atmosphere, contributing to global warming. Its levels have been growing strongly since 2007, and in 2014 the growth rate of methane in the atmosphere was double that of previous years, largely driven by biological sources as opposed to fossil fuel emissions.

Conventional wisdom refuted

The study, led by researchers at Royal Holloway, University of London shows that methane emissions have been increasing, particularly in the tropics. Researchers discovered that biological sources, such as methane emissions from swamps, make up the majority of increase.

"Our results go against conventional thinking that the recent increase in atmospheric methane must be caused by increased emissions from natural gas, oil, and coal production. Our analysis of methane's isotopic composition clearly points to increased emissions from microbial sources, such as wetlands or agriculture" said lead author Euan Nisbet from Royal Holloway, University of London's Department of Earth Sciences.

Methane growth rate doubles

Professor Nisbet says "Atmospheric methane is one of the most potent greenhouses gases. Methane increased through most of the 20th century, driven largely by leaks from the gas and coal industries."

He continued, "At the beginning of this century it appeared that the amount of methane in the air was stabilising, but since 2007 the levels of methane have started growing again. The year 2014 was extreme, with the growth rate doubling, and large increases seen across the globe."

Tropics identified as key source

The research shows that in recent years, the increase in methane has been driven by sharp increases in the tropics, in response to changing weather patterns. It is possible that the natural processes that remove methane from the atmosphere have slowed down, but it is more likely that there's been an increase of methane emission instead, especially from the hot wet tropics.

Professor Nisbet and his team, together with the US The National Oceanic and Atmospheric Administration (NOAA), have been looking at measurements and samples of air taken from places like Alert in the Canadian Arctic; Ascension, a UK territory in the South Atlantic; Cape Point, South Africa.

International collaboration leads to new conclusions

The research has been carried out by an international team of atmospheric scientists, led by Euan Nisbet, from Royal Holloway, University of London. Ed Dlugokencky, from the NOAA, Martin Manning from Victoria University, Wellington, New Zealand and a team from the University of Colorado's Institute of Arctic and Alpine Research, led by Jim White, have been working with collaborators from the UK, France, Canada, and South Africa.
