Move Over Mammogram

The image shows a scan of a human breast performed by photoacoustic computed tomography (or PACT) – a new imaging technology that may one day replace the typical X-ray mammograms that women over the age of 40 routinely undergo to check for the presence of breast cancer. Regular X-ray mammograms not only expose women to doses of radiation and are painful to endure, but they also don’t work well in women with particularly dense breast tissue – because the dense tissue can have the same appearance as a cancer. PACT, by contrast, is relatively painless, uses a near-infrared laser instead of X-rays and produces a detailed high-resolution picture of the vasculature rather than the tissue of the breast. This avoids the problems associated with tissue density, yet still enables detection of tumours, which are commonly associated with abnormal networks of blood vessels.

Neutrino Associated with Distant Blazar Jet

Explanation: With equipment frozen deep into ice beneath Earth’s South Pole, humanity appears to have discovered a neutrino from far across the universe. If confirmed, this would mark the first clear detection of cosmologically-distant neutrinos and the dawn of an observed association between energetic neutrinos and cosmic rays created by powerful jets emanating from blazing quasars (blazars). Once the Antarctican IceCube detector measured an energetic neutrino in 2017 September, many of humanity’s premier observatories sprang into action to try to identify a counterpart in light. And they did. An erupting counterpart was pinpointed by high energy observatories including AGILE, Fermi, HAWC, H.E.S.S., INTEGRAL, NuSTAR, Swift, and VERITAS, which found that gamma-ray blazar TXS 0506+056 was in the right direction and with gamma-rays from a flare arriving nearly coincidental in time with the neutrino. Even though this and other position and time coincidences are statistically strong, astronomers will await other similar neutrino – blazar light associations to be absolutely sure. Pictured here is an artist’s drawing of a particle jet emanating from a black hole at the center of a blazar.

16th century Genoese wrecks discovered off north coast of Corsica

Archaeologists with CEAN (Centre d’études en archéologie nautique) have identified the remains of two wrecks discovered in the Gulf of Saint-Florent on the island of Corsica during an archaeological survey programme initiated in 2005.

Between 2010 and 2015, they undertook the excavation of one of the two wrecks located not far from the Mortella tower. This operation involved the National Museum of Natural History, the CNRS, the Universities of the Sorbonne (Paris IV) and Corsica.

“In the 16th century,” says underwater archaeologist Arnaud Cazenave de la Roche, “Mediterranean shipbuilding was renowned throughout Europe and master carpenters, especially those from the Italian states, were sought after for the quality of their work and the high degree of their technical expertise. Today, this know-how is largely unknown because, in addition to the scarcity of writings, archaeological evidence is relatively scarce. The only 16th century wrecks of Mediterranean origin whose architectural remains have been studied are the wrecks of Villefranche sur Mer and Calvi. This observation makes the Mediterranean shipbuilding of the Renaissance period a research priority for the last 30 years.”

During its long history, Corsica has been the centre stage of rivalry between the great European powers. The sinking of the ships was part of a complex political situation revealing the divisions among Italian cities and the tension between France and Spain.

Archaeologists determined that the wrecks of the Mortella were not Spanish galleons as they had initially thought but ships of Genoese origin. The wreck studied could be that of the Ferrara or the Boscaina, a ship built in the Rapallo shipyard in 1517, a date determined from a dendrochronological study carried out by Swiss scientist Fabien Langenegger.

Arnaud Cazenave de la Roche explains the historical events that led to the ship’s sinking: “When Genoa was blockaded by the fleet of the League of Cognac which united the French fleets with those of the Pope, Andrea Doria and Venice, the ship was dispatched to Sicily in 1527, accompanied by another vessel, with the aim of loading wheat to supply the starving population of Genoa. The two ships were trapped in the bay of Saint-Florent in Corsica by French galleys. Unable to escape, the ships were unloaded and deliberately set on fire by their crews to prevent them from falling into enemy hands.”

“The design of the ship not only reflects the distinctive features of medieval ship-building, but also has certain technical innovations that foreshadow the modern era. These commercial vessels were most often armed with artillery guns intended to defend themselves against the privateers who infested the Mediterranean. One of the important findings of the mission was the uncovering of the base of the main mast, a wooden structure that has rarely been studied during this period. The material discovered is scarce: ceramics, glass, anchors, ropes, and artillery pieces.”

“The study was limited by technical and financial difficulties. The constraints imposed by decompression and safety issues and the very short working times dictated by the hyperbaric environment (50 minutes per diver per day) prevented the removal of the wreck. The archaeological analysis was also hampered by the fire that ravaged the vessel before it sank and by the general lack of structural remains”, concluded the archaeologist.

New archaeological research forces historians to reconsider the story of Iceland’s...

Archaeological excavation in East Iceland and C-14 dating of barley found in Viking Age ruins in Reykjavík threaten to topple the accepted account of Iceland’s settlement in the 9th and 10th centuries by Norse Vikings. Written sources suggest the first settler to arrive in Iceland was Ingólfur Arnarson who settled in Reykjavík in the year 874. New research suggests the first people arrived as much as 100 years earlier.

Archaeologists who have been excavating a site at the farm Stöð in Stöðvarfjörður fjord in East Iceland unearthed two large Viking Age longhouses. The two longhouses are very large compared to other Viking Age structures excavated in Iceland and Scandinavia. The site in Stöðvarfjörður was discovered by accident in 2003, and is only now being excavated by archaeologists.

The site in Stöðvarfjörður is not the first Viking Age site discovered by accident. In fact, most of the important archaeological finds in recent years have been totally accidental or at sites where nobody expected to find anything of importance.

Bjarni Einarsson, the archaeologist in charge of the dig told the local TV station Stöð 2 that the younger of the two houses was built on the ruins of the older structure, which measures as much as 40 meters (130 ft). Both structures are located beneath the “settlement layer”, a layer of volcanic tephra that fell sometime in the years 869-73, making both older than the “official” time of settlement which began in 874, according to the Icelandic Sagas and the Book of Settlement, medieval sources on the Viking Age and the settlement of Iceland.

in Iceland at present [Credit: Friðrik Þór]

Previous archaeological evidence has seemed to support the written record, although mounting evidence suggests a human presence decades prior to permanent settlement. Historians have also been taking a second look at the origin of Iceland’s settlers as more evidence is found of strong Celtic influences among the Viking Age settlers.

Bjarni told Stöð 2 that C-14 dating indicates the older structure was built shortly after the year 800, suggesting permanent settlement in the Eastfjords 70 years before Ingólfur Arnarson arrived in Reykjavík.

The nature of these first settlements remains a mystery, but Bjarni believes they were fishing and hunting camps, rather than permanent settlements. “Such camps were common in Scandinavia,” he points out. Local chiefs would send out teams of workers to establish camps in remote uninhabited areas during summer, where they hunted, fished and produced various goods. The camp in Stöðvarfjörður could have been used to fish, hunt seabirds and seals, as well as to produce oil from whale blubber and iron from bog ore. Most Viking era iron was smelted from bog iron.

The size of the longhouse, which is twice as larger than the longhouses excavated in Reykjavík, suggest an operation on a significant scale. The Reykjavík longhouses, which have been dated to the years around 870 measured 20 meters (66 ft), are currently among the largest ever excavated in Iceland.

The very name of the farm Stöð and the fjord Stöðvarfjörður seem to support this theory: Stöð translates as camp, station or base.

Such seasonal camps could have been used for decades before permanent settlement began. Bjarni believes they played a key role in the settlement of Iceland: “People would have come here to work part of the year, producing goods during summer to take home in the fall. They would have taken these goods home, as well as information about this new land. Based on this information people would then have been able to make an informed decision to settle here permanently.”

Scholar studies Jordan’s ancient Pella inhabitants through olive exploitation...

The archaeobotanical archive from Pella provides an “extraordinary record through time” of approximately 8,000 years of almost continual exploitation of plants by Pella’s inhabitants, Anne Dighton from The University of Queensland, Brisbane says.

as early as 6,200 BC [Credit: Anne Dighton]

The archive allows researchers to track change through time and examine the social and economic role of plants at key transitional periods, Dighton told The Jordan Times in a recent interview.

“I am very grateful to have been given the opportunity to analyse the archaeobotanical archive from Pella that is material from several decades of careful soil sampling at the site,” the scholar said.

“Olives and olive oil have been a significant part of the daily diet of people in this part of the world for millennia. What we had not realised was just how far back this might have been the case,” Dighton said, adding that excavation and analysis to date has shown that olive was being exploited in Jordan from as early as approximately 6,200 BC.

“This is exciting as it is among the earliest evidence in the world for significant exploitation of olive and is much earlier than has traditionally been thought. Finding out more about the form of this very early exploitation is one of the things that I intend to investigate in my doctoral research,” Dighton explained.

Moreover, there is also a view that olives were not growing naturally in the Pella environs at this time, and yet, there are significant quantities of olive material in occupation deposits at the site dating to this early period, the archaeologist added.

“To try and shed some light on this, one of the methods I will use is the analysis and identification of the wood charcoal from the site. In addition to helping us gain a better understanding of the palaeoenvironment through time generally, wood charcoal analysis will allow us to determine whether olive wood is present in the Late Neolithic phases at Pella,” Dighton underlined, adding that this will help scientists understand whether the olive remains are exploitation of locally occurring trees, or whether the olives were brought in from elsewhere.

The regional olive oil trade in the Bronze Age is still an unsolved puzzle:”It’s not clear how significant any potential olive trade or export at Pella might have been in the Bronze Age. My earlier research indicated that, while olives were being exploited from the Late Neolithic onwards, it was only during the Bronze Age that we see a recognisable signal suggestive of domestication of olives at Pella.”

This took the form of a significant change in size and size variation in the olive endocarps, or pits, indicating intensified exploitation leading to domestication, she explained.

She will be testing this theory further to see whether the changes we see in settlement patterns at Pella that indicate a population increase at the site during this time might be linked to the morphological change we see in the olives.

“It’s possible that the reason we see the domestication signal during the Bronze Age is that this represents an intensification of olive exploitation through the development of olive groves. Again, in addition to analysis of the olive remains themselves, wood charcoal analysis may prove key to understanding the more intensified exploitation of olive that we believe occurred, possibly in the Middle Bronze Age, by tracking changes through time in woodland vegetation composition,” the scholar said.

However, it is also possible that the ongoing analysis of recently-excavated Late Neolithic-Early Bronze Age samples may provide results that suggest domestication occurred much earlier and more in line with the significant olive exploitation we see in those earliest periods of occupation at Pella, Dighton underscored.

Archaeologists discover medieval graves in Sicily

Polish archaeologists have discovered over 800 years old burials during excavations near the medieval church of San Michele del Golfo near Palermo in Sicily. According to the scientists, the graves could belong to the Normans, descendants of the Vikings.

“Some of the dead buried in the cemetery were undoubtedly members of the elites or the clergy, as the form of some of the graves indicates”, says head of excavations Prof. Sławomir Moździoch from the Institute of Archaeology and Ethnology of the Polish Academy of Sciences in Wroclaw.

This year, archaeologists found a total of 10 burials, including three graves of women and two graves of children. The remaining skeletons were difficult to identify. According to the discoverers, the cemetery was associated with the church hospital mentioned in a document from the 12th century. Unfortunately, no equipment was found in any of the graves.

Researchers were able to determine the origin of the dead – there are many indications that they came from western Europe (northern France) – they were Normans, descendants of the Vikings.

“According to the local anthropologist, the tallness and massive build of skeletons of people buried here indicate this origin”, the scientist says. This is not a surprise for researchers.

“In the second half of the 11th century, the island was recaptured from the Arabs by a Norman nobleman, Roger de Hauteville”, explains the scientist. Interestingly, the construction of the fortified church started before the nearby city of Palermo was recaptured from the Muslims. That`s why the church was built on a hill, in a strategic place. It was a 3-apse building with one nave, erected on a cruciform plan.

This is not the first research season of Polish archaeologists in Sicily. During the last year`s work they also found burials. Researchers have the results of the first DNA analyses made by Prof. Wojciech Branicki from the Jagiellonian University. “These findings are consistent with our concept of the ‘northern’ pedigree of the church and the deceased buried here, because they show that the deceased had lighter shade of skin, hair and eyes compared to the then dominant communities in Sicily”, explains Prof. Moździoch.

Excavations were also carried out within the ruins of the medieval church. “The Western European form of the church, its architecture, but also discovered coins minted in Champagne and Lucca, indicate that its builders and users could have come from Normandy and the north of the Apennine peninsula”, the head of excavations believes. Research results confirm the earlier conclusions of researchers that the temple was built in the 12th century

“Our research has changed the previous theories concerning the church structure. It indicates that its form referred more to the western European churches of the 11th and 12th centuries than to the buildings of this type erected in Sicily during that period. To put it simply, the concept of construction was directly transferred from the north by the craftsmen brought from there”, concludes Prof. Moździoch.

The mission has also succeeded to uncover a Gilded Sliver Mummy Mask in one of the burial chambers of the main shaft attached to the Mummification Workshop, dating to the Saite-Persian Period (664-404 BC). The Mask belongs to a person who held the titles of ‘the Second Priest of Mut and the Priest of Niut-shaes’.

Preliminary microscopic examination suggests that it is made of gilded silver, and the eyes are inlayed with a black gemstone (possibly onyx), calcite and obsidian. The wig was also inlayed with gemstones that were once embedded in color pastes. The mask measures 23 x 18.5 cm. A research and conservation project is currently being planned for the mask.

Dr. Ramadan Badry Hussein, Director of Saqqara Saite Tombs Project and Professor at Tübingen University describes the discovery as “rare” and explains that the mummification workshop has a rectangular building constructed with mud brick and irregular limestone blocks. It has an entrance on the southwestern corner that leads into an open area with two large basins and a mud brick ramp between them.

The two basins are surrounded with mud brick walls. It is believed that they were for the natron and the preparation of the linen bandages. He states that the Mummification Workshop includes also an embalmer’s cachette with a 13.00 m. deep shaft that ends with a rectangular subterranean chamber, where a large corpus of pottery was found. This pottery included vessels, bowls and measuring cups inscribed with names of oils and substances used in the mummification.

The Mummification Workshop has also a large shaft (K 24) in the middle, which is used as a communal burial place. It measures 3.00 x 3.35 m x 30.00 m. Shaft K24 uniquely has several burial chambers, including a complex of burial chambers cut into the bedrock on a depth of 30.00 m. They are arranged on the sides of two hallways. The first hallway has an intact burial chamber on the west, where three decayed wooden coffins were found on top of the western end of a large limestone sarcophagus. A fourth mummy is found to the north of that sarcophagus. A large number of faience ushabti figurines were also found along the northern side of the sarcophagus.

Dr. Hussein pointed out that the middle wooden coffin, on top of the sarcophagus, is badly damaged, and the mummy inside it has a gilded mask that was found on top of the face of the mummy. The wooden coffin was once plastered and painted with an image of the goddess Nut, the mother of the god of the dead, Osiris.

The decoration also includes the titles of the owner of the mask along with his name. He is the Second Priest of the goddess Mut and the Priest of the goddess Niut-shaes, a serpent form of the goddess Mut. The theophoric name of the owner of the mask includes the name of the goddess Neith, the patron goddess of Dynasty 26. Pieces of the painted plaster carrying the rest of his name are still missing, and the mission is collecting more of them in order to read the full name of the deceased.

The Mission of the University of Tuebingen to Saqqara has started the implementation of state of the art technology in the documentation and recording of monuments, particularly the laser scanning and photogrammetry techniques. The Mission’s digital documentation activities included creation of 3D photogrammatic models and laser scans of the burial chambers of Padinist, Director of the Storage Department of the Royal Palace, Psamtek, Chief physician and Commander of the Libyan Mercenaries, and Amentayefnakht, Commander of the Recruits. The Mission also conducted a conservation project of the polychrome reliefs and inscriptions of these burial chambers.

Discovery of new petroglyph site set to rewrite Qatar’s ancient past

Qatar Museums (QM) has announced the discovery of a formerly unknown petroglyph site in the centre of the Qatari Peninsula.

The newly discovered site is spread across an area of around 15 hectares, making it the second largest rock carving site in the country after Al Jassasiya. This is the first time that a site of this kind is discovered away from Qatar’s coasts, thereby completely transforming the current archaeological map of the country, QM has said in a statement.

The new site contains petroglyphs that are commonly known as ‘rosette’ and consist of a central cupmark circularly surrounded by several other cupmarks. In the Gulf region, this type of rock carving is unique to Qatar and is believed to have been used for a children’s game.

Since last week, QM’s Department of Archaeology has been performing extensive survey activities to document the site in detail. It is expected that the new discovery will provide more accurate clues about the function and dating of the carvings, as well as their relationship with the other sites found around Qatar.

Commenting on the discovery, Faisal al-Naimi, director of the Department of Archaeology, said: “The newly discovered site is another addition to Qatar’s diverse archaeological locations and a testament to the impact that our ancestors have had on the land. We are still conducting site surveys and tests but believe that the well found close to the site gives us an idea about the Qatari community that lived here at a certain point in history.

“We also noticed that the number of ‘rosette’ carvings here far exceed the ones found in Al Jassasiya, making this site an important historical witness.”

QM’s Department of Archaeology was alerted about the site’s location after a call from Ali Mutar al-Dosari, whose family has lived in the area for generations. Since childhood, al-Dosari had noticed the carvings near the well but only realised their potential significance after hearing about QM’s work in archaeology and heritage conservation.

“Ever since I can remember, I have always been intrigued by these carvings and their story,” said al-Dosari. “When I heard about Qatar Museums’ work in the field of archaeology, I knew that I must contact them immediately. They arrived on the same day and, after conducting initial testing, informed us that the sites have an important historical significance. I am very pleased and proud to have contributed to preserving our identity and past.”

Since its inception, QM has been putting local communities, young and old, in touch with their past, reminding them of the skills, wisdom and struggles of their ancestors, the statement adds.

Astronauts Release U.S. Spacecraft Completing Cargo Mission

Orbital ATK – Cygnus CRS-9 Mission patch.

July 15, 2018

Expedition 56 Flight Engineers Alexander Gerst of ESA (European Space Agency) and Serena Auñón-Chancellor of NASA commanded the International Space Station’s Canadarm2 robotic arm to release the Cygnus cargo spacecraft at 8:37 a.m. EDT. At the time of release, the station was flying 253 miles above the Southeastern border of Colombia. Earlier, ground controllers used the robotic arm to unberth Cygnus.

Northrop Grumman CRS-9 Cygnus departure (S.S. J.R. Thompson Cygnus)

The departing spacecraft will move a safe distance away from the space station before deploying a series of CubeSats. Cygnus will remain in orbit for two more weeks to allow a flight control team to conduct engineering tests.
