Fighting ivory trafficking with forensic science

Fighting ivory trafficking with forensic science August 14, by Adrienne Kenyon, Columbia University Despite a strict ban on ivory trafficking in NY, these pieces were found for sale in Columbia University Two weeks ago, Kevin Uno was on a field expedition in Kenya when he got a message he’d been hoping for: The Lamont-Doherty Earth Observatory geochemist and his colleague, University of Washington research professor Samuel Wasser, use radiocarbon dating and DNA testing to determine when and where an elephant was killed; sampling this recently seized ivory would be an opportunity for them to find out whether it was recently harvested, and help law enforcement target the poachers responsible.

This is the first time that the team has been given permission to sample and test illegally trafficked ivory seized from vendors in the United States; Uno and Wasser have previously sampled ivory seized while in transit from Africa to Asia.

Radiocarbon dating is increasingly used in the field of textile research and old polychrome statues, but also objects made of ivory, stucco, paper, and parchment are dated with the technique. Especially after the introduction of the AMS technique, a boom of this type of research has been noticed.

British Museum This pointed oval plaque was discovered some time ago by the bare-fist fighter Jack Bradley while he was digging for flint artefacts. It is made from walrus ivory and is carved in high relief. Christ with a halo and dressed in a long robe is shown sitting in majesty on a rainbow. In His left hand is the Bible while the right hand is raised in blessing. Around the edge of the plaque is a raised frame. Originally, it was brilliant with bright paint and gold leaf. Four attachment holes in the plaque seem to have been made some time after it was first carved.

It is likely the plaque was removed from its original setting and reused, perhaps to decorate a box or shrine. The depiction of Christ in Majesty was popularly used in both manuscripts and ivories of this period. The dating of this piece is based on the style and technique of its decoration. The folds of Christ’s robe are restrained and static, which is similar to other sculpture and manuscript art of the eleventh century.

Elephant poachers are hard at work in Africa, and carbon dating proves it

Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the “radiocarbon age”, which is the age in “radiocarbon years” of the sample:

Nuclear physicist Elias Sideras-Haddad says he can determine when an elephant died as well as its age by a new carbon-dating technique applied to the tusks – a process made possible by the above.

While excavating, researchers found a coral file artifact from within the beach. The first Polynesian settlers sailed to Tonga between 2, and 2, years ago, according to new research. The findings, published Nov. Advertisement “The technique provides us with unbelievable precision in dating quite ancient materials,” said David Burley, a co-author of the study and an archaeologist at Simon Fraser University in Vancouver.

No playable sources found The new techniques could be used to trace the migration of Polynesia’s prehistoric seafarers as they colonized the archipelagos of the Pacific Ocean, he said. The Lapita people , the ancestors of modern-day Pacific Islanders , first sailed from coastal New Guinea roughly 5, years ago, reaching the Solomon Islands around 3, years ago and gradually expanding farther east toward what is now the archipelago Tonga, Burley told LiveScience.

Advertisement Across a string of Pacific islands, the Lapita left traces of their culture: The ancient inhabitants of Oceania likely used these coral files to smooth the surfaces of wooden objects or shell bracelets, Burley said. A nail file made from staghorn coral reef by the Lapita people at Polynesia’s oldest known settlement, Nukuleka. Using ultra-precise dating techniques, the researchers determined the first Polynesians arrived about 2, years ago.

Archaeologists determine when the Lapita migrated to an island by estimating the age of the earliest coral files there. Historically, they dated the coral files using radioactive carbon isotopes atoms of the same element with different weights. But precise numbers were elusive, because carbon dating can be off by a few hundred years. But instead of using radioactive carbon, the team used radioactive uranium and developed a method to date the ancient coral fragments with incredible precision.

Radiocarbon dating of elephant ivory tusks leads to conviction

Edited By James D. Abstract Estimating age in the archaeological record is the primary step in understanding the human past. Chronology provides a temporal dimension that distinguishes archaeology, paleontology, and geology from the disciplines of ethnography and ethnology. Increasingly better-defined methods of dating have radically enhanced our ability to address questions of cultural identity and ethnicity, as well as cultural change; an understanding of the primary methods that date the past is still critical to interpreting social process.

The facility to correlate an event or episode with an absolute point in time is crucial in solving many archaeological problems. A variety of methods can be used to establish chronology in archaeology.

It consists of dentine, made up of components which are both organic to provide the capacity for growth and repair and inorganic to provide rigidity and strength. Identification of the type of ivory is based on the composition of the dentine and its specific growth structure. Ivory is very reactive to its environment. It bleaches when exposed to light but the most severe changes are linked to changes in relative humidity and temperature.

Low relative humidity causes desiccation, shrinkage and cracking, while high relative humidity can cause warping and swelling. Heat fluctuations induce similar expansion and contraction.

Traders in illegal ivory sometimes use this clause as a cover, claiming that their wares are older than they really are. Radioisotope analysis. Cerling and his colleagues applied a forensic science method to objectively estimate the age of samples in seized ivory shipments—radiocarbon dating.

But the study, published in the Proceedings of the National Academy of Sciences of the United States of America, found that 90 percent of the ivory in 14 large seizures between and came from animals that had died less than three years before the tusks were confiscated. The findings show that high-profile environmental campaigns, international treaties and millions of dollars of aid and NGO funds over decades have failed to solve a poaching crisis in Africa, where tusks from slain animals are quickly finding their way to market.

The lag time between killing and confiscation was generally between six and 35 months, with ivory from east Africa making it into shipments faster, the study said. The authors, using a radiocarbon dating technique known as Carbon , found that, of ivory specimens examined, only one came from an animal that had expired longer than six years beforehand. The lack of old or stored ivory among the contraband may show that governments are securing stockpiles better.

It may also stem from the fact that a number of countries including Gabon and Kenya have destroyed stockpiles. The authors said their technique for revealing lag times between date of death and seizure could also be applied to illegal trade in other animal parts, providing useful information to police, governments and conservationists.

This translates to “Ivory Coast” in French, so it seems kinda pointless. Anyway, if you want to make a good impression on local women, don’t refer to their country by its colonial name. It’s home to 25 million people, but the ones we’re most interested in are the women. Reasons to Date Cote D’Ivoire Women Women here are very traditional, so man-hating feminists are thin on the ground here.

Actually they’ll be thin on the ground everywhere soon, thanks to them not having kids. We can be grateful for that much at least. Ivorian women, on the other hand, are naturally beautiful, warm, nurturing and care about how you feel. You’ll never hear them complain about your masculine traits, because that’s what they’re biologically attracted to. Another perk is that women here are not at all materialistic, which gives them an advantage over girls from certain other African nations.

They also have no issue with dating Western guys, or dating guys of any race for that matter. Foreign men have been visiting Cote d’Ivoire since about , so you won’t be the first white guy they’ve ever met.

What factors are involved when buying netsuke? What is a netsuke? Netsuke singular and plural initially served both functional and aesthetic purposes. The traditional form of Japanese dress, the kimono, had no pockets. Women would tuck small personal items into their sleeves, but men suspended their tobacco pouches, pipes, purses, writing implements, and other items of daily use on a silk cord passed behind their obi sash.

These hanging objects are called sagemono. The netsuke was attached to the other end of the cord preventing the cord from slipping through the obi. A sliding bead ojime was strung on the cord between the netsuke and the sagemono to allow the opening and closing of the sagemono. The entire ensemble was then worn, at the waist, and functioned as a sort of removable external pocket. All three objects netsuke, ojime and the different types of sagemono were often beautifully decorated with elaborate carving, lacquer work, or inlays of rare and exotic materials.

Subjects portrayed in netsuke include naturally found objects, plants and animals, legends and legendary heroes, myths and mystical beasts, gods and religious symbols, daily activities, and myriad other themes. Many netsuke are believed to have been talismans.

Subsequent sales[ edit ] The two largest collections of Benin Bronzes are located in the Ethnological Museum of Berlin and in the British Museum in London, while the third largest collection is located in several museums in Nigeria principally the Nigerian National Museum in Lagos. Often, their return has been considered an icon of the repatriation of the African continent.

The artifacts have become an important example in the international debate over restitution, comparable to that of the Elgin Marbles. In , the museum’s curator Hermann Braunholtz declared that, although made individually, of the plaques acquired by the Museum in , 30 were duplicates; because they were identical representations, he determined that they were superfluous for the museum and were sold.

The bronze surfaces are designed to highlight contrasts between light and metal. The descendants of these artisans still revere Igue-Igha , as the person who introduced the art of casting to the Kingdom of Benin.

A technique called radiocarbon dating helped Canadian authorities convict a Toronto-based auction house and its owner this week for attempting to sell illegal ivory tusks.

Face painting is mentioned in the Old Testament Ezekiel Keville, Green Since the Egyptians, each subsequent civilization invented unique words that referred to cosmetics and fragrance as one science, but the science eroded after Rome. Anthropologists speculate that primitive perfumery began with the burning of gums and resins for incense.

Richly scented plants were fused into animal and vegetable oils for ceremonial anointings and for pleasure. From 7, to 4, BC, the fatty oils of olive and sesame were combined with fragrant plants to create the original Neolithic ointments. When the Egyptians were learning to write and make bricks in 3, BC, they were also importing large quantities of myrrh.

The earliest recorded items of Egyptian commerce included spices, gums and other fragrant plants that were reserved mainly for religious use. Dyes and paints were used to color the skin, body and hair. They rouged their lips and cheeks, stained their nails with henna, and lined their eyes and eyebrows heavily with kohl.
