The discovery, which predates the dawn of farming, suggests that stone age man's first cultivated meal may have been a bowl of porridge made from grains growing wild and is the earliest known instance of human consumption of oats.
The find was made by a team led by Marta Mariotti Lippi at the University of Florence in Italy who made analysed starch grains found on the artefact.
They found evidence that the stone's creators also heated the grains before grinding them, perhaps to dry them out in the colder climate of the time and make the grain easier to grind and longer-lasting.
This multi-stage process would have been time consuming, but beneficial, while turning it into flour would have been a good way to transport it, which was important for Palaeolithic nomads.

Evidence of porridge consumption in Scotland dates back to 4,000 BC, when oats and other grains began to be cultivated by the first farmers.
Mariotti Lippi’s team hopes to continue studying ancient grinding stones to find out more about the stone age plant diet.
The stone was found in the Grotta Paglicci, Apulia, which was home to stone age hunter gatherers between 34,000 and 32,000 years ago and contains mural paintings, depicting horses and handprints. Images of goats, cows, a serpent, a nest with eggs, and a hunting scene have also been found engraved on bone.
Archaeologist Matt Pope, of University College London, said that the find shed light on the diet of early humans and the spread of food cultivation.

He said: “There is a relationship there to be explored between diet, experimentation with processing plant food and cultural sophistication.
“We’ve had evidence of the processing of roots and cattails, but here we’ve got a grain, and a grain that we’re very familiar with.
“If we were to look more systematically for ground stone technology we would find this is a more widespread phenomenon.”
The study is published in Proceedings of the National Academy of Sciences.

The head of an ancient Greek statue of extraordinary artistic and historical value will finally arrive back in Italy on Friday – almost three decades after being illegally ripped from the ground.

The stunning statue had been on display at the J.Paul Getty museum in Los Angeles but was eventually discovered to be Italian property after archaeologists identified one of the statue's beard curls among fragments found at a looted site in Sicily.
The unique terracotta head depicts Hades, god of the underworld. He is shown with a bushy blue beard and curly hair, which still bear a good deal of the blue and red pigments with which they were painted 2,400 years ago.
But the mission to bring Hades home has taken years.
“It was great to be able to work with our Sicilian counterparts to identify the provenance of the head,” a spokesperson for the museum told The Local.
"The process of identifying the head took two years and the museum agreed to give it back in 2013. Since then it's been in storage while we waited for instructions from Sicily for its eventual return. Officials finally arrived to pick up the statue this week.”
The head had been on display in Los Angeles since 1985, when the museum acquired it from Belgian businessman - and long time partner of former US First Lady Jacqueline Kennedy - Maurice Tempelsman, for $500,000 (€460,000).

Templeman sold the piece through successful London art-dealer Robin Symes, who specialized in fencing looted antiques, often of Italian provenance. In January 2005, Symes was sentenced to 21 years in jail (of which he served a mere seven) for trafficking stolen pieces.
On Friday, the statue will finally take pride of place at Enna's Adione museum, a stone's throw from the site where it was originally taken: an outcome which has satisfied Italians on both sides of the Atlantic.
“We owe it above all to the archaeologists who helped identify that ceramic lock of blue hair among the remains of a fraudulent dig site,” said Italy's Consul General in LA, Antonio Verde.
In January 2014, several other pieces of looted art were returned to Enna's Adione museum by the J. Paul Getty museum.
Items included a two-metre Greek marble statue of Venus, which the museum had also bought from Symes in 1988 for an eye-watering $18 million (€16.4 million).
Former curator of the museum, Marion True, was placed on trial in Italy in 2005, but was acquitted after the charges against her expired in 2012.
But the institution is not alone in giving Italy back illegally acquired objects. In recent years pieces have been returned from other high-profile institutions including the Metropolitan Museum of Art in New York.
According to one Italian prosecutor, artworks from more than 100,000 raided tombs worth in excess of €460 million have been illegally taken out of the country.

For the earliest Egyptologists, a trip to the Egyptian Museum in Turin was considered indispensable. The museum's new director is seeking to return the almost 200-year-old museum to its one-time prominence, boosted by an overhaul of the collection and exhibit space of near-pharaonic proportions.

Museum director Christian Greco, who arrived in Turin 10 months ago, well into an ambitious five-year reinstallation of the museum's considerable treasures, aims to make the Egyptian Museum the second-most important in the world, after Cairo.
"Our museum needs to be back on the international scene," Greco said in an interview in front of the ancient Temple of Ellesjia on Tuesday, as the museum showed off its five-year, 50-million-euro ($53.6-million) reinstallation. `'For too many years we have been absent. For too many years, the focus has been on building and renovating the museum."

The museum, founded in 1824, is filled with treasures found in digs commissioned by Savoy kings and completed with the finds of Italian Egyptologist Ernesto Schiaparelli. The vast holdings include a captivating statue of Ramses II, one of the world's most important papyrus collections and nearly the entire contents of an architect's tomb dating back well over 3,000 years.
The large-scale renovations nearly doubled the space, allowing many artifacts to be taken out of storage and a more complete and modern exposition of those already on display. The museum remained open during the years of work, rotating closures of wings.

"It is a very important improvement from an archaeological and Egyptological point of view," said Guillemette Andreu, former director of Egyptology at the Louvre in Paris and member of the Turin Egyptian Museum board who toured the museum on Tuesday. She praised the chronological organization of the reinstallation from the 4th century B.C. to the Coptic period, new lighting and modern showcases.
Andreu said the Turin collection is unique because alongside masterpieces, it includes many objects that describe daily lives, funerary customs, religion as well as architecture and philosophy. "Even if you are not a scholar of Egypt, you can see how great this civilization was," she said.

The revamp puts the 6,500 objects on display in their archaeological context, transforming it from what Greco called `'an encyclopedia of Egyptology from A to Z," and includes 3-D films using historical photos that depict the moment of discovery.
"Turin has a fantastic collection and an incredible history, and to have it redisplayed in a modern museological way is fantastic," said Neal Spencer of the British Museum, who attended the Turin museum's opening and is on the advisory board. `'It is a very immersive experience. The collection really can tell the story of Egypt across several millennia."

The museum already belongs on the European itinerary of any Egyptologist, amateur or otherwise, along with the British Museum in London, the Louvre in Paris and the Egyptian Museum and Papyrus Collection in Berlin. But Greco's ambition is to make it a more integral part of the scientific community, restoring its standing to the one it enjoyed when one of Egyptology's founding figures, Jean-Francois Champollion, famously declared: `'The road to Memphis and Thebes passes through Turin."
Greco, a 39-year-old Italian who was previously at the National Museum of Antiquities in Leiden, the Netherlands, announced on Tuesday that the Turin museum in May will join an ongoing, 40-year-old dig in Saqqara, Egypt, that was founded by his former employer and the University of Leiden. Greco is also working on a coffin project with the Vatican and trying to organize a joint exposition of artifacts from the craftsmen's village of Medina with the Louvre.

"I suspect Greco has a lot of irons in the fire that are going to be very exciting that will be of real benefit to Egyptology and to world culture," said Kara Cooney at the University of California, Los Angeles, who will be traveling to Turin in June to look at the museum's coffins.
The museum is among the top 10 visited in Italy, with a record 567,000 visitors last year. Greco could like to increase that to more than 700,000. The opening of the expanded museum a month before the Expo 2015 world's fair in Milan, just a 40-minute train ride away, is expected to bring a boon in visitors, along with the rare exposition of the Shroud of Turin from April 19-June 24.

The copper used to make Ötzi’s axe blade did not come from the Alpine region as had previously been supposed, but from ore mined in southern Tuscany. Ötzi was probably not involved in working the metal himself, as the high levels of arsenic and copper found in his hair had, until now, led us to assume.

His murder over 5,000 years ago seems to have been brought about due to a personal conflict a few days before his demise, and the Iceman, despite his normal weight and active life-style, suffered from extensive vascular calcification.
Scientists from all over the world presented these and other new insights, at the 3rd Bolzano Mummy Congress. To celebrate the 25th anniversary of Ötzi’s discovery, the three days of the Congress, from 19th to 21st September, are all dedicated to the Iceman.
Since the Iceman came on the scene on 19th September 1991, he has not ceased to fascinate scientists from all over the world. No corpse has been more thoroughly investigated. “In terms of his significance for science, Ötzi is not simply an isolated mummy discovery. He could be seen as a typical European from earlier times and is precious for this reason alone,” explained the anthropologist Albert Zink from EURAC Research, the scientific leader of the congress.
“Ötzi is so well preserved as a glacier mummy and through this alone, he serves us researchers as a model for developing scientific methods which can then be used on other mummies,” said Zink.
“What concerns us most these days is to know who the Iceman was, what role he played in society and what happened to him in the last days of his life. Sophisticated procedures, now available to scientists, are continually supplying us with new evidence,” said Angelika Fleckinger, Director of the South Tyrol Museum of Archaeology which co-organised the Congress.
Links to Central Italy
One surprising new fact has been unearthed which concerns the most extraordinary item amongst Ötzi’s equipment – the valuable copper axe. In contrast to what had previously been presumed, the copper used in the blade does not derive from the Alpine region (researchers had suggested East or North Tyrol as the most likely provenance) but from Central Italy. Professor Gilberto Artioli‘s archaeometallurgy research group at the University of Padua has discovered that the metal had been obtained from ore mined in South Tuscany.
In order to determine its origin, Italian scientists took a tiny sample from the blade and compared the proportion of lead isotope – a kind of “finger print” of the ore deposits which remains unchanged in any objects subsequently made from the ore – with the corresponding data from numerous mineral deposits in Europe and the entire Mediterranean region. The result pointed unequivocally to South Tuscany.
“No one was prepared for this finding. We will commission further analyses in order to double-check these first results” stressed Angelika Fleckinger. If the original results are confirmed, this new evidence will give researchers some interesting food for thought.
Was Ötzi as a trader travelling possibly as far as the area around today’s Florence? What was the nature of the trading and cultural links with the south in those days? Did the exchange of goods also involve movements of the population? That is to say, did people from the south venture into the Alpine region and vice versa?
“This is a particularly exciting insight especially with respect to questions about population development”, explained Albert Zink.
Was he or was he not involved in smelting copper?
Another question long debated amongst the scientific community, is whether Ötzi was perhaps involved himself in the process of copper smelting. Scientists have advocated this thesis because raised arsenic and copper levels have been measured in the mummy’s hair, a fact which might possibly be explained, for example, by breathing in the smoke which is released when melting and pouring metal.
Geochemist Wolfgang Müller of Royal Holloway, University of London, who had already used isotope analysis to establish Ötzi’s South Tyrol origins, has now turned to this question once more. Using highly developed methods of analysis such as laser mass spectrometry and speciation analysis, Müller’s team examined not just hairs but also samples from Ötzi’s nails, skin and organs for possible heavy metal contamination.
His, so far still provisional, findings suggest that the hypothesis that Ötzi was involved in processing metal was premature. Müller did indeed find slightly raised arsenic values in the nail sample, but not in other tissue samples. Raised copper levels were only present at the extremities and this correlates with other change indicators, and thus it is doubtful if one can establish a heavy metal contamination for Ötzi’s actual life time: raised values might also be due to environmental influences over the 5,000 years since his death.
Radiological investigations with the latest CT equipment
A new computer tomography (CT) scan of the Iceman was undertaken by radiologists Paul Gostner and Patrizia Pernter in January 2013 in the Department of Radiology of Bozen-Bolzano Hospital. To do this they used a CT-scanner of the latest generation which, thanks to its large opening, allowed the doctors to run Ötzi rapidly through the machine from head to toe despite the way his arm is angled. In addition to the vascular calcification in the arteries of his stomach and legs which had already been known about, the superior image allowed doctors to spot three small areas of calcification near to the outflow tracts of the heart which had hitherto escaped their notice. This substantiates the earlier finding made by molecular biologists in EURAC that Ötzi had a strong genetic predisposition to cardiovascular diseases and that this was probably also the main reason for his general arteriosclerosis.
Investigations of a “profiler”
Ötzi was murdered. The arrow head discovered in 2001 in his left shoulder suggests this. But what were the circumstances surrounding the crime? In 2014 the South Tyrol Museum of Archaeology commissioned Chief Inspector Alexander Horn of the Munich Criminal Investigation Department to investigate the “Ötzi Murder Case” using the latest criminological methods.
Horn interrogated various “acquaintances” of the murder victim such as archaeologists from the museum who had been looking after Ötzi for years, or experts from forensic medicine, radiology and anthropology. Members of the project team also took part in an on-site inspection of the location in Schnals Valley in South Tyrol Italy where the body was found.
The results of this investigation were that Ötzi probably did not feel threatened shortly before his murder, because the situation at the Tisenjoch location where he was found indicates that he had been resting while enjoying a hearty meal. In the days prior to the murder he had incurred an injury to his right hand, probably as a result of defensive action during the course of a physical altercation. No further injuries could be found, and this might serve to indicate that he had not been defeated in this particular conflict.
The arrow shot, which was probably fatal, seems to have been launched from a great distance and took the victim by surprise, from which we may infer that it was an act of treachery. Further medical findings suggest that the victim fell and that the perpetrator used no further violence. The perpetrator probably did not wish to risk a physical altercation, but instead chose a long distance attack to kill the Iceman. As valuable objects such as the copper axe remained at the crime scene, theft can be excluded as the motive.
The reason for the offence is more likely to be found in some sort of personal conflict situation, in a previous hostile encounter – “a behavioural pattern which is prevalent even today in the bulk of murder crimes”, as Alexander Horn explained.
The Italian mafia is selling assault rifles to Islamic State leaders in Libya in return for looted archaeological treasures, according to an Italian newspaper.

The feared ‘Ndrangheta gangsters sell on the priceless artefacts to Russian and Asian collectors.
La Stampa reports that the Calabrian network, which dominates Europe’s drug trade, works with the Camorra in Naples to buy Kalashnikov rifles and rocket-propelled grenade launchers smuggled out of Ukraine and Moldova by the Russian mafia.
The armaments are then traded in return for ancient Roman and Greek statues that Isis fighters have dug up illegally in Libya, which was a colony of the two ancient cultures. Isis has ruled over swathes of the country for months.
A journalist from La Stampa posed as a collector to be taken to a salami factory in southern Italy by a member of an ‘Ndrangheta clan from Lamezia in Calabria. For $87,000 he was offered the marble head of a Roman sculpture looted from Libya.
The Mafioso also showed photographs of a larger head from a Greek statue, for sale at $1.2 million.
Antiquities are brought from Libya to the Calabrian port of Gioia Tauro by Chinese-operated cargo ships, it is claimed. The treasures are sold on to collectors from Russia, China, Japan and the Gulf. After expanding into Libya, Isis has been pinned back by local militias. The jihadists, however, are believed to have tried to profit from trafficking in artefacts, as they have done in Iraq and Syria.
Libyan archaeologists working to protect the country’s five UNESCO-listed sites have received death threats.
Italian investigators have long suspected the mafia of selling guns to Isis. “In Naples, Islamic militias and the Camorra have been trading guns and drugs since the 1990s,” a veteran investigator said yesterday (Sunday).
The gangsters have also been involved in the wholesale looting of Etruscan Roman tombs in Italy. Trading guns for artefacts with Isis is a natural evolution of its business. The widespread excavation and selling of Greek and Roman treasures boomed in Libya after the death in 2011 of Colonel Gaddafi, well before the arrival of Isis.
A rare 4ft marble statue believed to have been dug up in the ancient city of Cyrene in 2011 and worth $3.2 million was found in a west London warehouse two years after the uprising.
Susan Kane, a Libyan expert at Oberlin College in Ohio, said: “There was a major land grab after the revolution and more earth has been moved since 2011 than in the preceding centuries. Antiquities are turning up and there is a great synergy between trafficking them, drugs and arms.”

An unidentified fossilised bone in a museum has revealed the size of a fearsome abelisaur and may have solved a hundred-year old puzzle.
Artist impression of abelisaur [Credit: Imperial College London]
Alessandro Chiarenza, a PhD student from Imperial College London, last year stumbled across a fossilised femur bone, left forgotten in a drawer, during his visit to the Museum of Geology and Palaeontology in Palermo Italy. He and a colleague Andrea Cau, a researcher from the University of Bologna, got permission from the museum to analyse the femur. They discovered that the bone was from a dinosaur called abelisaur, which roamed the Earth around 95 million years ago during the late Cretaceous period.
Abelisauridae were a group of predatory, carnivorous dinosaurs, characterised by extremely small forelimbs, a short deep face, small razor sharp teeth, and powerful muscular hind limbs. Scientists suspect they were also covered in fluffy feathers. The abelisaur in today's study would have lived in North Africa, which at that time was a lush savannah criss-crossed by rivers and mangrove swamps. This ancient tropical world would have provided the abelisaur with an ideal habitat for hunting aquatic animals like turtles, crocodiles, large fish and other dinosaurs.
By studying the bone, the team deduced that this abelisaur may have been nine metres long and weighed between one and two tonnes, making it potentially one of the largest abelisaurs ever found. This is helping researchers to determine the maximum sizes that these dinosaurs may have reached during their peak.
Alfio Alessandro Chiarenza, co-author of the study from the Department of Earth Science and Engineering at Imperial, said: "Smaller abelisaur fossils have been previously found by palaeontologists, but this find shows how truly huge these flesh eating predators had become. Their appearance may have looked a bit odd as they were probably covered in feathers with tiny, useless forelimbs, but make no mistake they were fearsome killers in their time."
The fossil originated from a sedimentary outcrop in Morocco called the Kem Kem Beds, which are well known for the unusual abundance of giant predatory dinosaur fossils. This phenomenon is called Stromer's Riddle, in honour the German palaeontologist Ernst Stromer, who first identified this abundance in 1912. Since then scientists have been asking how abelisaurs and five other groupings of predatory dinosaurs could have co-existed in this region at the same time, without hunting each other into extinction.
Now the researchers in today's study suggest that these predatory dinosaur groups may not have co-existed so closely together. They believe that the harsh and changing geology of the region mixed the fossil fragment records together, destroying its chronological ordering in the Kem Kem beds, and giving the illusion that the abelisaurs and their predatory cousins shared the same terrain at the same time. Similar studies of fossil beds in nearby Tunisia, for example, show that creatures like abelisaurs were inland hunters, while other predators like the fish eating spinosaurs probably lived near mangroves and rivers.
Chiarenza added: "This fossil find, along with the accumulated wealth of previous studies, is helping to solve the question of whether abelisaurs may have co-existed with a range of other predators in the same region. Rather than sharing the same environment, which the jumbled up fossil records may be leading us to believe, we think these creatures probably lived far away from one another in different types of environments."
Fossilised femora are useful for palaeontologists to study because they can determine the overall size of the dinosaur. This is because femora are attached to the thigh and tail muscles and have scars, or bumps, which tell palaeontologists where the ligaments and muscles were attached to the bone and how big those muscles and ligaments would have been.
Andrea Cau, co-author from the University of Bologna, said: "While palaeontologists usually venture to remote and inaccessible locations, like the deserts of Mongolia or the Badlands of Montana, our study shows how museums still play an important role in preserving specimens of primary scientific value, in which sometimes the most unexpected surprises can be discovered. As Stephen Gould, an influential palaeontologist and evolutionary biologist, once said, sometimes the greatest discoveries are made in museum drawers."
The study is published in the journal Peer J. Chiarenza did the underpinning analysis with Cau while at the University of Bologna.
The next step will see the team looking for more complete remains from these predatory dinosaurs trying to better understand their environment and evolutionary history.

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.
Scientists have discovered that stunted growth can be a genetic response to ocean acidification, enabling some sea creatures to survive high carbon dioxide levels, both in the future and during past mass extinctions.

Using natural CO2 seeps as test sites, the international team of marine scientists and palaeontologists have studied the way in which sea snails cope in more acidic conditions ‒ simulating the change in seawater chemistry that will occur in future as more atmospheric CO2 is absorbed by the ocean.
The researchers say their findings, published in Nature Climate Change, provide an explanation as to why marine species that survived previous mass extinction events were much smaller – a phenomenon known as the ‘Lilliput effect’.
The research was funded by the EU MedSeA project and the UK Ocean Acidification Research Programme, and involved researchers from 10 institutions including Plymouth University, the University of Southampton, the Natural History Museum, London, and colleagues in Italy, Monaco, Norway and New Caledonia.
Its results provide a stark warning about the impact that continuing ocean acidification could have on marine ecosystems unless we drastically slow the rate of carbon dioxide emissions.
Dr Vittorio Garilli, at Paleosofia-APEMA, Palermo, said: “Two species of snails growing at shallow water CO2 seeps were smaller than those found in normal pH conditions, and adapted their metabolic rates to cope with the acidified seawater. These physiological changes allowed the animals to maintain calcification and to partially repair shell dissolution.”
Professor Jason Hall-Spencer, of the School of Marine Science and Engineering at Plymouth University, said: “Organisms that have been exposed to elevated CO2 levels over multiple generations provide valuable insights both into changes we can expect in marine ecosystems as CO2 emissions continue to rise unchecked, and into past mass extinctions."
“Not only do they demonstrate a similar magnitude and direction of body size change as fossil organisms, but they also reveal the physiological advantages of dwarfing,” added Professor Marco Milazzo at Palermo University.
Measurements showed that the shells from high CO2 seawater were about a third smaller than those in “normal” environments. Some of the snails were taken to the Marine Environmental Studies Laboratory at the International Atomic Energy Agency in Monaco, where their calcification rates were measured in aquaria.
Study co-leader Dr Riccardo Rodolfo-Metalpa, from the Institut de Recherche pour le Développement, said: “They developed a surprising ability to calcify and cope with shell dissolution at pH values which were thought too low for calcification to occur.”
The results – published in the paper Physiological advantages of dwarfing in surviving extinctions in high CO2 oceans – confirmed the theory that the snails had adapted to the conditions over many generations.
Professor Richard Twitchett, of the Department of Earth Sciences at the Natural History Museum, said: “The fossil record shows us that mass extinctions and dwarfing of marine shelled species are repeatedly associated with episodes of past global warming. It is likely that similar changes will increasingly affect modern marine ecosystems, especially as the current rate of ocean acidification and warming is so rapid."
Professor Hall-Spencer added: “It is critical that we understand the mechanisms by which certain species survive chronic exposure to elevated CO2 since emissions of this gas are already having adverse effects on marine foodwebs and putting food security at risk.”

As armed groups in Syria and Iraq destroy priceless archaeological sites, European authorities and dealers are on high alert for smaller, looted artefacts put on sale to help finance the jihadists' war.

Stolen-art expert Chris Marinello, director of Art Recovery International, said he has been shown photographs of items being offered from Syria that were "clearly looted right out of the ground".
"You could still see dirt on some of these objects," he told AFP.
They included cylinder seals, Roman bottles and vases, although Marinello said it was unclear whether the items were still in Syria, were in transit or had arrived in the key markets of Europe and the United States.
Concerns about looting during the Syrian war have increased following the advance of the Islamic State group through parts of Syria and Iraq, and recent propaganda videos showing their destruction of ancient sites such as Nimrud.
The UN Security Council in February demanded UN states act to stop the trade in cultural property from those two countries, amid warnings that they represented a significant source of funding for the militant group.
Experts say it is impossible to put a value on antiquities looted from Syria, which has been home to many civilisations through the millennia, from the Canaanites to the Ottomans.
The London-based International Association of Dealers in Ancient Art (IADAA) estimates the entire legitimate antiquities market in 2013 was worth between 150 and 200 million euros ($160-215 million).
Marinello said reputable dealers are "being very careful not to touch anything that could remotely be part of this recent wave of looting".
But Hermann Parzinger, an archaeologist and president of the Germany-based Prussian Cultural Heritage Foundation, said there was an "enormous market" from private buyers.
He warned that the cultural costs were huge, telling AFP: "The context which is so important to reconstruct the history of these civilisations is completely destroyed."
Italy has proposed that world heritage body UNESCO create a military taskforce to protect cultural sites in war zones, but many experts believe little can be done to stop the current destruction.
Instead, they are forced to wait until the conflict ends and watch in horror as priceless historic sites are destroyed and the spoils gradually emerge onto the market.
Vernon Rapley, a former head of the art and antiquities squad at London's Metropolitan Police, expects many Syrian items to be held back to avoid flooding the market, as occurred after the US-led invasions of Iraq and Afghanistan.
The looted artefacts were likely to be "hauled up in warehouses either in the country or near the country, and only linked to the art trade in small pieces and at a later stage", he told AFP.
Stephane Thefo, who leads an Interpol unit dedicated to fighting the illegal trafficking of cultural goods, agreed that many items may disappear for years -- but insisted that tackling the trade was the best way to combat looting.
The French policeman would like to see tougher national laws on trafficking of cultural goods, something Germany is currently considering.
"We have to act by seeking to narrow markets for the illicit trade, hoping that by curbing the demand, the supply would eventually decrease," Thefo said.
Identifying looted objects is no easy task, however, not least because cultural crime is rarely a police priority.
The law puts the onus on the authorities to prove an item is illegal and a long delay in an artefact being sold, or multiple owners, make it hard to establish provenance.
At a conference at the V&A museum in London this week on the destruction of cultural property in conflict areas in Iraq and Syria, Mali, Libya and Yemen, archaeologists stressed the need for proper inventories of heritage sites.
They noted that objects that have been photographed and digitally catalogued are more likely to be recovered.
Interpol is currently building a database of stolen objects, and James Ede, a London dealer and IADAA board member, urged cultural bodies to share their information with dealers.
"This material will necessarily surface on the open market sooner or later. The challenge therefore is to identify it and where possible to return it when it is safe to do so," he said.

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.
The team, which also included researchers from UCL (University College London) and the Universita' del Sacro Cuore of Rome, analysed more than 4,000 previously collected DNA samples from 64 different populations, covering multiple locations in Europe, Africa and the Americas. Since migration has generally flowed from Africa and Europe to the Americas over the last few hundred years, the team compared the 'donor' African and European populations with 'recipient' American populations to track where the ancestors of current-day North and South Americans came from.
'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.
The Museo Civico Archeologico is hosting Egypt. Millennia of Splendour. Beneath the two towers, the splendour of a civilisation that lasted thousands of years and has always fascinated the entire world, has sprung back to life: the Egypt of the pyramids, pharaohs and multiform gods, but also that of sensational discoveries, captivating archaeology, passionate collecting and rigorous scholarship.
The exhibition ‘Egypt’, which is being held at the Museo Civico Archeologico in Bologna, is not just an exposition of high visual and scientific impact, but also an unprecedented international enterprise: the Egyptian collection of the National Museum of Antiquities in Leiden, Netherlands – among the top ten in the world – and that of the Bologna museum – among the most important in Italy for the quantity, quality and state of conservation of its collections – have been brought together in an exhibition space measuring around 1,700 metres, filled with art and history.
500 finds, dating from the Pre-Dynastic Period to the Roman Period, gave been brought from the Netherlands to the Bologna museum. And, together with the masterpieces from Leiden and Bologna, the exhibition also includes important loans from the Museo Egizio in Turin and the Museo Egizio in Florence, creating a network of the most important Italian museums.
For the first time, the masterpieces of the two collections are being displayed side by side, including the Stele of Aku (Twelfth–Thirteenth Dynasty, 1976–1648 BC), the ‘major domo of the divine offering’, with a prayer describing the otherworldly existence of the deceased in a tripartite world divided into sky, earth and the beyond; gold items attributed to General Djehuty, who led the Egyptian troops to victory in the Near East for the great conqueror Pharaoh Thutmose III (1479–1425 BC); the statues of Maya, superintendent of the royal treasury of Tutankhamen, and Merit, a chantress of the god Amun, (Eighteenth Dynasty, reigns of Tutankhamen and Horemheb, 1333–1292 BC), the most important masterpieces in the National Museum of Antiquities in Leiden have left the Netherlands for the first time for the Bologna exhibition; and, among the numerous objects attesting to the refined lifestyle of the most wealthy Egyptians, a Mirror Handle (1292 BC) in the shape of a young woman holding a small bird in her hand.

Lastly, for the first time 200 years after the discovery of his tomb in Saqqara, the exhibition offers the unique and once-in-a-lifetime opportunity to see the important Reliefs of Horemheb reunited: Horemheb was the head commander of the Egyptian army during the reign of Tutankhamen, then rising to become the final sovereign of the Eighteenth Dynasty, from 1319 to 1292 BC and the reliefs are divided between the collections in Leiden, Bologna and Florence.
Thousands of years of the history of a unique civilisation revealed in a major exhibition that brings together masterpieces from important world collections and tells of the pyramids and pharaohs, the great captains and priests, the gods and other divinities, and the people that made Egyptian history and that, thanks to discoveries, archaeology and collecting, never stop enchanting, revealing, intriguing, fascinating and charming generation after generation.
The Seven Exhibition Sections
The Pre-Dynastic and Archaic Periods – At the Origins of History: The transition from raw material to form, from the oral tradition to the written one and from prehistory to history was a fundamental moment for Egyptian civilisation. The Leiden collection is rich in materials documenting the central role played by nature during this long cultural and artistic evolution.

The exhibition opens with a selection of these objects, which are strikingly modern in style, including a vase from the Naqada IID Period (named for a site in Upper Egypt and datable between 3375 and 3325 BC) decorated with ostriches, hills and water motifs. The scene depicted on this vase takes us back to an Egypt characterised by a flourishing landscape later changed over time by climatic changes. Ostriches, here painted red, along with elephants, crocodiles, rhinoceros and other wild animals were common in the Nile region at the time.
The Old Kingdom – A Political/Religious Model Destined for Success and its Weaknesses: The historic period of the Old Kingdom (from the Third to the Sixth Dynasty, roughly between 2700 and 2192 BC) is known for the pyramids and for the consolidation of a bureaucracy at the apex of which stood an absolute sovereign, considered a god on earth and lord of all of Egypt.
This definition of State and its worldly and otherworldly rules, which were highly elitist, are well documented by funerary objects, of which the Leiden museum has a particularly rich collection, including a calcite (alabaster) table for offerings.
Offerings to the deceased were a fundamental part of the funerary ritual, ensuring life after death. The uniqueness of this table, which belonged to a high state official named Defdj, lies in its circular shape, which was unusual, as well as the repetition of the concept of the offering as indicated by the inscription, the sculpted receptacles and, most importantly, the central depiction corresponding to the hieroglyph hotep (offering), or a table upon which one places a loaf of bread.

The Middle Kingdom – The God Osiris and a New Perspective on Life in the Afterworld: The end of the Old Kingdom and the period of political breakdown that followed it led to major changes in Egyptian society, within which the individual had greater responsibility for his own destiny, including in the afterworld. Any Egyptian with the means to build a tomb complete with a sufficient funerary assemblage could now aspire to eternal life. The god Osiris, lord of the afterworld, became Egypt’s most popular divinity.
Many steles now in Leiden and Bologna came from his temple in Abydos, one of Egypt’s most important cult centres. Among them is that of Aku, major domo of the divine offering, who dedicated the stele to Min-Hor-nekht, the form of the ithyphallic god Min worshipped in the city of Abydos. Aku’s prayer to the god describes an otherworldly existence in a tripartite world: the sky, where the deceased were transfigured into stars, the earth, where the tomb was the fundamental point of passage from life to death, and the beyond, where Osiris granted the deceased eternal life.
From the Middle to the New Kingdom – Territorial Control at Home and Abroad: The defeat of the Hyksos, ‘princes from foreign lands’ who invaded and governed northern Egypt for a few generations, marked the beginning of the New Kingdom. An extremely aggressive foreign policy enriched Egypt, and this was one of its periods of greatest splendour. The social class of professional warriors rose to the top of the state hierarchy and spawned a number of ruling dynasties.

The wealth and prestige of these soldiers was also expressed in the production of sophisticated objects, including the gold items attributed to Djehuty, a general under the pharaoh Thutmose III. The Egyptian goldsmith’s art has survived in works of high artistic and economic value, an example being the pectoral element on view in the exhibition.
This piece is a sophisticated exemplar attributed to the tomb of General Djehuty, the man to whom the sovereign Thutmose III entrusted control of his foreign territories. Representing a blue lotus flower, a symbol of rebirth and regeneration, it must have served as the central element of an elaborate pectoral. The scroll engraved on the back suggests that the piece was given personally by Thutmose III.
The Saqqara Necropolis of the New Kingdom: The Leiden and Bologna museums can be considered ‘twins’ in a certain sense, since they house two important groups of antiquities from Saqqara, one of the necropolises of the city of Memphis. During the New Kingdom, this early Egyptian capital returned to its role as a strategic centre for the expansionist policy of the sovereigns of the Eighteenth Dynasty.
This is seen in the funerary monuments of high state officials who held administrative, religious and military roles, including the tombs of the superintendent of Tutankhamen’s royal treasury, Maya, and his wife, Merit, chantress of Amun, and that of Horemheb, head commander of Tutankhamen’s army and the pharaoh’s crown prince.

The statues of Maya and Merit arrived in the Netherlands in 1829 as part of the collection of Giovanni d’Anastasi. More than a century and a half would pass before, in 1986, a British/Dutch archaeological expedition identified the tomb from which they came, southeast of the pyramid of Djoser at Saqqara. These statues, which are the greatest masterpieces in the collection of the National Museum of Antiquities in Leiden, left the Dutch museum for the first time to be displayed in the exhibition.
It should be noted that, when the Egypt Exploration Society of London and the National Museum of Antiquities in Leiden began excavation work southeast of the Djoser pyramid in 1975, the goal was to find the tomb of Maya and Merit. It was therefore a great surprise when they instead discovered the burial of General Horemheb, who had capped off his stunning career by becoming the last sovereign of the Eighteenth Dynasty.
His tomb, which has a temple structure, is characterised by a pylon entrance, three large courts and three cult chapels facing onto the innermost court, which has a peristyle structure. This court is where most of the reliefs preserved in Leiden and Bologna were found, narrating Horemheb’s most important military feats against the populations bordering Egypt: the Asians, Libyans and Nubians.
The New Kingdom – Prosperity after the Conquest: Refined furnishings, musical instruments, table games and jewellery: these are just a few of the luxury goods attesting to the widespread prosperity enjoyed in Egypt as a result of the expansionist policy of the sovereigns of the New Kingdom. Through these sophisticated objects, it is possible to conjure up moments of everyday life, imagining what it was like living inside a royal palace or the residence of a high official. One example in the exhibition is a mirror handle in the graceful, sensual shape of a young women holding a small bird in her hand.

Egypt in the First Millennium: In the first millennium BC, Egypt was characterised by the increasingly clear weakness of its central power to the advantage of local governors who gave themselves the role of ruling dynasts. The loss of political and territorial power weakened Egypt’s defence capacity at its borders, opening the way for Nubian, Assyrian and Persian invasions. The temples remained strong centres of power, and managed a sizeable portion of the economy and the transmission of knowledge, taking on the role of a political intermediary between the ruling power and the devout populace.
Many of the masterpieces on view in the exhibition were part of the funerary assemblages of priests and came from important temple areas. Among them is the sarcophagus of Peftjauneith, which represents the likeness of the god Osiris, wrapped in a linen shroud and with a green face evoking the concept of rebirth. The refined decoration of this sarcophagus confirms the high rank of its owner (the superintendent of the possessions of a temple in Lower Egypt) in the temple sphere. Of particular note is the interior scene of the sky goddess Nut swallowing the sun every evening (to the west) to then give birth to it in the morning (to the east).
Alexander the Great’s conquest of Egypt in 332 BC ended the ‘pharaonic’ phase of Egyptian history. The period of Greek domination was begun by his successors, the Ptolemies, the last of whom was the renowned Cleopatra VII.
The golden decline of Egypt would continue for many more centuries, beyond the Roman conquest in 31 BC up to Arab domination in the sixth century AD.
The dialogue between old and new, local and foreign that distinguished the Greco-Roman period brought a return to high artistic achievements, including the celebrated Fayum portraits, exquisite examples of which from the Leiden collection are on view in the exhibition

Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden giant collapses present a realistic hazard today around volcanic islands, or even along more distant continental coasts. The study appears today in the journal Science Advances.
Geologists think that the eastern slope of Fogo volcano crashed into the sea some 65,000 to 124,000 years ago, leaving a giant scar where a new volcano can be seen growing in this satellite image [Credit: NASA]
"Our point is that flank collapses can happen extremely fast and catastrophically, and therefore are capable of triggering giant tsunamis," said lead author Ricardo Ramalho, who did the research as a postdoctoral associate at Columbia University's Lamont-Doherty Earth Observatory, where he is now an adjunct scientist. "They probably don't happen very often. But we need to take this into account when we think about the hazard potential of these kinds of volcanic features."
The apparent collapse occurred some 73,000 years ago at the Fogo volcano, one of the world's largest and most active island volcanoes. Nowadays, it towers 2,829 meters (9,300 feet) above sea level, and erupts about every 20 years, most recently last fall. Santiago Island, where the wave apparently hit, is now home to some 250,000 people.
There is no dispute that volcanic flanks present a hazard; at least eight smaller collapses have occurred in Alaska, Japan and elsewhere in the last several hundred years, and some have generated deadly tsunamis. But many scientists doubt whether big volcanoes can collapse with the suddenness that the new study suggests. Rather, they envision landslides coming in gradual stages, generating multiple, smaller tsunamis. A 2011 French study also looked at the Fogo collapse, suggesting that it took place somewhere between 124,000-65,000 years ago; but that study says it involved more than one landslide. The French researchers estimate that the resulting multiple waves would have reached only 45 feet--even at that, enough to do plenty of harm today.
A handful of previous other studies have proposed much larger prehistoric collapses and resulting megatsunamis, in the Hawaiian islands, at Italy's Mt. Etna, and the Indian Ocean's Reunion Island. But critics have said these examples are too few and the evidence too thin. The new study adds a new possible example; it says the estimated 160 cubic kilometers (40 cubic miles) of rock that Fogo lost during the collapse was dropped all at once, resulting in the 800-foot wave. By comparison, the biggest known recent tsunamis, which devastated the Indian Ocean's coasts in 2004 and eastern Japan in 2011, reached only about 100 feet. (Like most other well documented tsunamis, these were generated by movements of undersea earthquake faults--not volcanic collapses.)

Santiago Island lies 55 kilometers (34 miles) from Fogo. Several years ago, Ramalho and colleagues were working on Santiago when they spotted unusual boulders lying as far as 2,000 feet inland and nearly 650 feet above sea level. Some are as big as delivery vans, and they are utterly unlike the young volcanic terrain on which they lie. Rather, they match marine-type rocks that ring the island's shoreline: limestones, conglomerates and submarine basalts. Some weigh up to 770 tons. The only realistic explanation the scientists could come up with: A gigantic wave must have ripped them from the shoreline and lofted them up. They derived the size of the wave by calculating the energy it would have taken to accomplish this feat.
To date the event, in the lab Ramalho and Lamont-Doherty geochemist Gisela Winckler measured isotopes of the element helium embedded near the boulders' surfaces. Such isotopes change depending on how long a rock has been lying in the open, exposed to cosmic rays. The analyses centered around 73,000 years--well within the earlier French estimate of a smaller event. The analysis "provides the link between the collapse and impact, which you can make only if you have both dates," said Winckler.
Tsunami expert Bill McGuire, a professor emeritus at University College London who was not involved in the research, said the study "provides robust evidence of megatsunami formation [and] confirms that when volcanoes collapse, they can do so extremely rapidly." Based on his own work, McGuire s says that such megatsunamis probably come only once every 10,000 years. "Nonetheless," he said, "the scale of such events, as the Fogo study testifies, and their potentially devastating impact, makes them a clear and serious hazard in ocean basins that host active volcanoes."
Ramalho cautions that the study should not be taken as a red flag that another big collapse is imminent here or elsewhere. "It doesn't mean every collapse happens catastrophically," he said. "But it's maybe not as rare as we thought."

In the early 2000s, other researchers started publishing evidence that the Cape Verdes could generate large tsunamis. Others have argued that Spain's Canary Islands have already done so. Simon Day, a senior researcher at University College London has sparked repeated controversy by warning that any future eruption of the Canary Islands' active Cumbre Vieja volcano could set off a flank collapse that might form an initial wave 3,000 feet high. This, he says, could erase more than nearby islands. Such a wave might still be 300 feet high when it reached west Africa an hour or so later he says, and would still be 150 feet high along the coasts of North and South America. So far, such studies have raised mainly tsunamis of publicity, and vigorous objections from other scientists that such events are improbable. A 2013 study of deep-sea sediments by the United Kingdom's National Oceanography Centre suggests that the Canaries have probably mostly seen gradual collapses.
Part of the controversy hangs not only on the physics of the collapses themselves, but on how efficiently resulting waves could travel. In 1792, part of Japan's Mount Unzen collapsed, hitting a series of nearby bays with waves as high as 300 feet, and killing some 15,000 people. On July 9, 1958, an earthquake shook 90 million tons of rock into Alaska's isolated Lituya Bay; this created an astounding 1,724-foot-high wave, the largest ever recorded. Two fishermen who happened to be in their boat that day were carried clear over a nearby forest; miraculously, they survived.
These events, however, occurred in confined spaces. In the open ocean, waves created by landslides are generally thought to lose energy quickly, and thus to pose mainly a regional hazard. However, this is based largely on modeling, not real-world experience, so no one really knows how fast a killer wave might decay into a harmless ripple. In any case, most scientists are more concerned with tsunamis generated by undersea earthquakes, which are more common. When seabed faults slip, as they did in 2004 and 2011, they shove massive amounts of water upward. In deep water, this shows up as a mere swell at the surface; but when the swell reaches shallower coastal areas, its energy concentrates into in a smaller volume of water, and it rears up dramatically. The 2004 Indian Ocean earthquake and tsunami killed 230,000 people in 14 countries; the 2011 Tohoku event killed nearly 20,000 in Japan, and has caused a long-term nuclear disaster.
James Hunt, a tsunami expert at the United Kingdom's National Oceanography Centre who was not involved in the study, said the research makes it clear that "even modest landslides could produce high-amplitude anomalous tsunami waves on opposing island coastlines." The question, he said, "is whether these translate into hazardous events in the far field, which is debatable."
When Fogo erupted last year, Ramalho and other geologists rushed in to observe. Lava flows (since calmed down) displaced some 1,200 people, and destroyed buildings including a new volcano visitors' center. "Right now, people in Cape Verde have a lot more to worry about, like rebuilding their livelihoods after the last eruption," said Ramalho. "But Fogo may collapse again one day, so we need to be vigilant."

Archaeologists announced Wednesday they have discovered hundreds of writing tablets from Roman London - including the oldest handwritten document ever found in Britain - in a trove that provides insight into the city's earliest history as a busy commercial town.

Researchers from >Museum of London Archaeology uncovered more than 400 wooden tablets during excavations in London's financial district for the new headquarters of media and data company Bloomberg.
So far, 87 have been deciphered, including one addressed "in London, to Mogontius" and dated to A.D. 65-80 - the earliest written reference to the city, which the Romans called Londinium.
Sophie Jackson, an archaeologist working on the site, said the find was "hugely significant."
"It's the first generation of Londoners speaking to us," she said.
The Romans founded London after their invasion of Britain in A.D. 43. The settlement was destroyed in a Celtic rebellion led by Queen Boudica in A.D. 61, but quickly rebuilt.
The documents show that only a few years after it was established, London was already a thriving town of merchants and traders. The records include references to beer deliveries, food orders and legal rulings.
One tablet carries the date Jan. 8, A.D. 57, making it Britain's earliest dated hand-written document. Fittingly for a city that is now the world's commercial capital, it's about money - an ancient IOU in which one freed slave promises to repay another "105 denarii from the price of the merchandise which has been sold and delivered."
The wooden tablets were preserved in the wet mud of the Walbrook - then a river, now a buried stream.
"The water keeps out the oxygen that would normally cause decay," Jackson said. "Our sticky Walbrook mud is like the ash of Pompeii or the lava of Herculaneum" - Roman towns in Italy preserved by volcanic eruptions.
In Roman times, the tablets were covered in wax, on which words could be inscribed with a stylus. The wax has not survived, but some of the writing penetrated to the wood and can still be read.
Classicist Roger Tomlin, who deciphered the inscriptions, said looking at the ancient handwriting had been "fun."
"You're thinking your way into the hand of someone else who lived 1,900 years ago," he said. "Your eyes are setting foot where man has never been before, at least not for a very long time."
Two ancient skeletons unearthed at a cemetery in London may have been of Chinese origin, overturning longstanding assumptions about the history of the Roman Empire and Britain's capital city.

Using cutting-edge techniques, a team of archaeologists and scientists examined dental enamel samples from over 20 sets of human remains dated from between the 2nd and 4th centuries AD.
Dr Rebecca Redfern, curator of human osteology at the Museum of London, revealed two of the skeletons found at the site in Lant Street, Southwark, had been identified as possibly being of Chinese origin.
"This is absolutely phenomenal. This is the first time in Roman Britain we've identified people with Asian ancestry and only the 3rd or 4th in the empire as a whole", she told BBC Radio 4's The World at One,
The find challenges the dominance of the traditional view that Roman Britain, and specifically “Londinium” as it was then known, was a relatively homogenous society.
It also suggests the Roman and Chinese empires may have had more interaction than many historians had previously thought.
Crucially though, it raises the possibility that trade took place between Rome and China outside of the famous Silk Road.

While previous archaeological work has shown the multicultural nature of the ancient city and its importance as a major trading hub, this is only the second time the bones of an individual of possibly Chinese origin have been found at a Roman site, the first being the discovery of a possibly Asian man in Vagnari, Italy.
Writing in >The Journal of Archaeological Science, Dr Redfern said: “The expansion of the Roman Empire across most of western Europe and the Mediterranean, led to the assimilation and movement of many ethnically and geographically diverse communities.
"Its power and wealth meant that it also had trade connections for raw materials and products, such as silk throughout Europe, Africa and also to the east, including India and China.
"Many people travelled, often vast distances, for trade or because of their occupation, for example in the military, or their social status, for example if they were enslaved."
Archaeologists and historians are divided as to the the explanation behind the possible presence of Chinese individuals in Roman Britain.
The findings raise the possibility that Chinese traders settled in the area, and may have even set up their own trading communities.
However, in her journal article, Dr Redfern went on to add: “It may well be that these individuals were themselves or were descended from enslaved people originating from Asia, as there were slave-trade connections between India and China, and India and Rome."

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."

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."
