Melting Arctic ice reveals treasure trove of hunting tools

Washington, April 27 (ANI): Scientists have discovered ancient hunting tools in the Mackenzie Mountains as the warming temperatures melt thousands of years old ice patches.

Tom Andrews, an archaeologist with the Prince of Wales Northern Heritage Centre in Yellowknife and lead researcher on the International Polar Year Ice Patch Study, said: “We”re just like children opening Christmas presents. I kind of pinch myself.”

Ice patches are accumulations of annual snow that, until recently, remained frozen all year.

For millennia, caribou seeking relief from summer heat and insects have made their way to ice patches where they bed down until cooler temperatures prevail.

Hunters noticed caribou were, in effect, marooned on these ice islands and took advantage.

Andrews said: “I”m never surprised at the brilliance of ancient hunters anymore. I feel stupid that we didn”t find this sooner.”

Ice patch archaeology is a recent phenomenon that began in Yukon.

In 1997, sheep hunters discovered a 4,300-year-old dart shaft in caribou dung that had become exposed as the ice receded.

Scientists who investigated the site found layers of caribou dung buried between annual deposits of ice. They also discovered a repository of well-preserved artefacts.

Andrews first became aware of the importance of ice patches when word about the Yukon find started leaking out. ”

He said: “We began wondering if we had the same phenomenon here.”

In 2000, he cobbled together funds to buy satellite imagery of specific areas in the Mackenzie Mountains and began to examine ice patches in the region.

Five years later, he had raised enough to support a four-hour helicopter ride to investigate two ice patches. The trip proved fruitful.

Andrews said: “Low and behold, we found a willow bow.”

That discovery led to a successful application for federal International Polar Year funds which have allowed an interdisciplinary team of researchers to explore eight ice patches for four years.

The results have been extraordinary.

Andrews and his team have found 2400-year-old spear throwing tools, a 1000-year-old ground squirrel snare, and bows and arrows dating back 850 years.

Biologists involved in the project are examining dung for plant remains, insect parts, pollen and caribou parasites.

Others are studying DNA evidence to track the lineage and migration patterns of caribou.

Andrews also works closely with the Shutaot”ine or Mountain Dene, drawing on their guiding experience and traditional knowledge.

He said: “The implements are truly amazing. There are wooden arrows and dart shafts so fine you can”t believe someone sat down with a stone and made them.” (ANI)

New gene may provide better immune defense against anthrax

Washington, Sept 9 (ANI): Scientists from University of California have identified a gene in anthrax-causing bacteria that could be used as a potential therapeutic target for the deadly disease.

The ClpX gene in bacterium Bacillus anthracis not only contributes to the severity of the anthrax disease but also makes it more difficult for a patient’s immune system to fight the infection.

Inhibiting this gene can prompt body’s natural defence mechanism to better fight the disease.

Mattias Collin, of Lund University, and Marc A. Williams, of the University of Rochester, praised the study and said that this might provide a new way to treat anthrax poisoning.

“This study has indeed identified a potential treasure trove in ClpX”, Colin and Williams wrote. (ANI)

Doomed Chandrayaan-1 has already yielded useful data on Moon’s mineralogy

Washington, September 1 (ANI): The Indian Space Research Organization (ISRO) might have prematurely terminated the country’s first moon exploration mission after it lost radio contact with Chandrayaan-1 over the weekend, but the probe is already said to have yielded a treasure trove of useful data.

This suggestion comes from Carle Pieters, a planetary geologist at Brown University in Rhode Island, the principal investigator of the Moon Mineralogy Mapper (M3), a NASA instrument on Chandrayaan-1.

Part of the M3 mission was to determine the distribution of elements and minerals on the moon’s surface, data that NASA had hoped would be useful for future manned missions to the moon or other planets.

Pieters says that before the probe prematurely ended, the M3 instrument had successfully completed a cursory global survey of mineralogy on the moon.

According to her, that first step was supposed to set the stage for higher-resolution mapping of the lunar surface.

“(But) even with the low-resolution data we have from the first phase, we have several new and completely unexpected discoveries,” National Geographic News quoted her as saying.

She did not give any information as to what those discoveries might be, as other scientists are still reviewing the data.

Expressing “enormous disappointment” at the early loss of Chandrayaan-1, she revealed that she and her colleagues were looking into a future flight of a duplicate M3 instrument.

“When you see fantastic results and taste success, it’s almost criminal not to plan for the future,” she said. (ANI)

Archaeological site in American county predates Egypt’s first known pyramids

Washington, June 22 (ANI): A team of archaeologists, in eastern Snohomish County, US, has found a treasure trove of artifacts from the Olcott period, 4,500 to 9,000 years ago, which even predates the first known pyramids in Egypt.

“The developer accidentally bought himself one of the most significant sites in Washington State,” Allyson Brooks, the state’s historic preservation officer told The Herald.

“The site is extremely significant for our understanding of the first inhabitants of the Pacific Northwest,” she added.

Earlier, a developer in 2007 uncovered thousands of artifacts, including spear points, stone knives and scraping tools – while performing a survey on land where he planned to build more than a dozen homes.

The ancient trove, investigated with just a few small test digs, put those plans on hold.

The tools catalogued by archaeological consultants during the initial survey are probably a fraction of what remains below the soil.

Initial estimates put the artifacts at up to 9,000 years old, which is almost 4,500 years older than the first known pyramids in Egypt or the apex of the Indus Valley Civilization on the Indian subcontinent, both dated to around 2,600 B.C.

Scores of similar areas are known throughout the state. Brooks and others said this one is remarkable because it is undisturbed and rich with artifacts.

“This site gives us a lot of opportunities to discover a lot of history,” said Shawn Yanity, the Stillaguamish tribal chairman. “It’s so rich with history, it just needs to be preserved,” he added.

From 17 test holes each about the size of a small wastepaper basket, archaeology consultants dug up thousands of artifacts.

Longtime Tulalip leader Stan Jones said the find is extremely important to tribal history.

According to him, there might be a way to use some of the artifacts in a Tulalip cultural museum expected to open soon.

Yanity, the Stillaguamish chairman, hopes all of the tribes with a stake in the process can work together. The chance to rediscover their common past could also be a great opportunity to train tribal archaeologists. (ANI)

Climate change threatens Siberian lake’s ecological balance

Washington, May 1 (ANI): An analysis by a joint US-Russian team has determined that Siberia’s Lake Baikal, the world’s largest and most biologically diverse lake, faces the prospect of severe ecological disruption as a result of climate change.

The analysis was done by Marianne V. Moore, of Wellesley College in Massachusetts, and five coauthors, including four from Irkutsk State University in Russia.

Lake Baikal is considered a treasure trove for biologists and was designated a World Heritage Site by UNESCO because a high proportion of its rich fauna and flora are found nowhere else.

Perhaps the most alarming imminent threat stems from the dependence of the lake’s food web on large, endemic diatoms, which are uniquely vulnerable to expected reductions in the length of time the lake is frozen each winter.

Moore and colleagues note that Lake Baikal’s climate has become measurably milder over recent decades, and that annual precipitation is expected to increase.

The average ice depth in the lake is known to have decreased in recent decades, and the ice-free season to have increased.

Changes in the lake’s food-web composition have been documented.

Future shortening in the duration of ice cover is expected to curtail the growth of the lake’s endemic diatoms, because unlike most diatoms, they bloom under the ice in springtime and are highly dependent on ice cover for their reproduction and growth.

The diatoms constitute the principal food of tiny crustaceans abundant in the lake, and these are in turn preyed upon by the lake’s fish.

Moreover, the crustaceans could be affected by changes in the transparency of the ice, an expected result of shifting precipitation patterns and changes in wind dynamics.

Shortened periods of ice cover and changes in the ice’s transparency may also harm the Baikal seal, the lake’s top predator and the world’s only exclusively freshwater seal.

Because the seals mate and give birth on the ice, premature melting of the ice forces them into the water before molting and drastically reduces their fertility.

A warmer, wetter climate may be the principal threat to Lake Baikal’s unique biological heritage, but it is not the only one.

The secondary effects of climate change, including greater nutrient inputs and industrial pollution from melting permafrost, may also exact a toll on an already-stressed ecosystem. (ANI)

NASA’s Kepler mission begins hunt for planets like Earth

Washington, April 17 (ANI): NASA’s Kepler mission has taken its first images of the star-rich sky where it will soon begin hunting for planets like Earth.

The new images show the mission’s target patch of sky, a vast starry field in the Cygnus-Lyra region of our Milky Way galaxy.

One image shows millions of stars in Kepler’s full field of view, while two others zoom in on portions of the larger region.

“Kepler’s first glimpse of the sky is awe-inspiring,” said Lia LaPiana, Kepler’s program executive at NASA Headquarters in Washington. “To be able to see millions of stars in a single snapshot is simply breathtaking,” she added.

One new image from Kepler shows its entire field of view – a 100-square-degree portion of the sky, equivalent to two side-by-side dips of the Big Dipper.

The regions contain an estimated 14 millions stars, more than 100,000 of which were selected as ideal candidates for planet hunting.

Two other views focus on just one-thousandth of the full field of view.

In one image, a cluster of stars located about 13,000 light-years from Earth, called NGC 6791, can be seen in the lower left corner.

The other image zooms in on a region containing a star, called Tres-2, with a known Jupiter-like planet orbiting every 2.5 days.

“It’s thrilling to see this treasure trove of stars,” said William Borucki, science principal investigator for Kepler at NASA’s Ames Research Center at Moffett Field, California.

“We expect to find hundreds of planets circling those stars, and for the first time, we can look for Earth-size planets in the habitable zones around other stars like the sun,” he added.

Kepler will spend the next three-and-a-half years searching more than 100,000 pre-selected stars for signs of planets.

It is expected to find a variety of worlds, from large, gaseous ones, to rocky ones as small as Earth.

The mission is the first with the ability to find planets like ours – small, rocky planets orbiting sun-like stars in the habitable zone, where temperatures are right for possible lakes and oceans of water.

“Everything about Kepler has been optimized to find Earth-size planets,” said James Fanson, Kepler’s project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“Our images are road maps that will allow us, in a few years, to point to a star and say a world like ours is there,” he added. (ANI)

“King of Bling” tomb sheds light on ancient Peru

Washington, April 12 (ANI): A 1,500-year-old tomb of the Moche Indian “king of bling”, found in Peru at the base of an eroded mud-brick pyramid, has yield a treasure trove of artifacts, which are shedding light on ancient times in the country.

According to a report in National Geographic News, the finds include 19 golden headdresses, various pieces of jewelry, and two funerary masks, as well as skeletons of two other men and a pregnant woman.

The tomb’s mysterious contents and location, far from known Moche capitals, could shed new light on this little-known culture of Peru’s arid northern coast, according to archaeologist Steve Bourget, of the University of Texas at Austin.

Thriving between A.D. 100 and 800, the highly agricultural Moche Indians are known in large part by their stepped pyramids, jewelry-filled tombs, and exquisite pottery and art.

Located some 475 miles (750 kilometers) north of Lima, the newfound tomb was found at the base of Huaca el Pueblo, a mud-brick, stepped pyramid that has eroded into a high, round mound.

The Lord of Ucupe, as locals have come to call the entombed Moche leader, was in his early thirties when he died.

For entombment, the lord was dressed in full regalia.

His body was covered with a tunic and train of tiny gilded copper plates, and his face was covered with two funerary masks, which is a first, according to Bourget.

A necklace of four-inch (ten-centimeter), disk-shaped silver rattles encircled his neck.

On his head was a gilded crown. Six more crowns and ten V-shaped headdresses called diadems were arrayed on top of his body.

Still another diadem was folded in half and placed atop six metal war clubs to serve as a mat for his lifeless body.

“The Lord of Ucupe was then wrapped in a large bundle made of reed and textile, along with artifacts suggestive of political status,” said Bourget, who co-led the team that found the tomb with Bruno Alva of the Museum Tumbas Reales de Sipan. top it all was placed a final diadem, the first treasure found by the archaeologists as they brushed away the layers of dirt, probably from a cave-in, filling the originally hollow tomb. he lord was entombed atop another man. At the second man’s side was yet another man, who himself was atop a pregnant woman. We don’t know the relationships between the leader and the other males,” Bourget said. “And this woman may have been a concubine or a wife. She may have died (of natural causes) while pregnant,” he added. here were no marks on the bones indicating that the people had been sacrificed. (ANI)

Treasure trove of artifacts recovered from Blackbeard’s 18th-century ship

Washington, April 1 (ANI): Archaeologists have recovered a treasure trove of artifacts from a recently recovered ship of the infamous 18th-century pirate Blackbeard.

According to a report in the National Geographic News, some of the newfound relics add to evidence that the ship belonged to the pirate.

“We feel pretty comfortable that that’s what this is,” said Marke Wilde-Ramsing, director of the Queen Anne’s Revenge project for the North Carolina Office of State Archaeology.

Underwater archaeologists from the North Carolina Department of Cultural Resources have been excavating the wreck, which lies 22 feet (7 meters) underwater a few miles off Beaufort, North Carolina, since 1997.

Among the discovered artifacts is a brass navigational instrument known as a chart divider.

Navigational instruments were favorite targets of looting pirates, because the tools could easily be sold or traded, according to archaeologist David Moore of the North Carolina Maritime Museum, who is working on the wreck site.

On March 26, 2009, two fleurs-de-lis (iris flowers)-the royal symbol of France-were revealed on an apothecary weight from a shipwreck off the coast of North Carolina, archaeologists said in March 2009.

Originally stuck to other nested weights, but separated via an electrolysis process, the weight and a fleur-de-lis-shaped keg spigot found in the shipwreck are among the strongest evidence that the ship was originally French-a key to tying the ship to Blackbeard.

The pirate captured the French ship Le Concorde and renamed it Queen Anne’s Revenge in 1717.

Le Concorde’s surgeon, who was forced to serve briefly in Blackbeard’s crew, may have owned the weights, designed for pharmaceuticals.

According to experts, pirates could have also used the weights to measure gold dust. (ANI)

Darwin ‘spent more on food than books during college days’

London, Mar 22 (ANI): Charles Darwin’s life during college days was quite different from what many would expect. He used to spend very little time studying or in lectures, preferring to shoot, ride and collect beetles, suggest newly discovered bills.

Historians have gained new insight into Darwin’s life as a college student after unearthing bills that record personal details of how he spent his money.

According to the bills, the revolutionary scientist happily paid others to carry out menial tasks for him, such as stoking his fire and polishing his shoes.

However, when it came to books, there is very little evidence to support the fact that he invested in textbooks, or that he did much else to further his studies.

The records were found in six previously overlooked college books, and are due to be published online on the Complete Works of Charles Darwin website (darwin-online.org.uk).

Darwin’s time at Cambridge, from 1828 to 1831 is also one for which there is a comparative shortage of information.

In total, Darwin’s college bills amounted to around 637 pounds over the three years, which did not include the 14 pounds he paid for his BA degree in 1831 or the 12 pounds he spent collecting his MA in 1836, following his return from the Beagle voyage.

The bills also show that in addition to the basic college dinner ration of a joint of meat and a glass of beer, he was prepared to spend money on fresh vegetables each day.

“Before this, we didn’t really know very much about Darwin’s daily life at Cambridge at all,” The Guardian quoted Dr John van Wyhe, director of the Darwin website, as saying.

“It had been assumed that there were no significant traces of his time here left to discover, which meant that we were short of information about one of the most formative parts of his life.

“Now, in his 200th anniversary year, we have found a real treasure trove right in the middle of Cambridge,” he said.

“How much he spent on alcohol, for example, or to have his horse stabled, we still don’t know,” added Van Wyhe, a science historian at the University of Cambridge and founder of the website. (ANI)

More than 4,000 prehistoric artifacts of stone and bone discovered in Vietnam

Hanoi (Vietnam), March 16 (ANI): Archaeologists have found more than 4,000 ancient artifacts of stone and bone in an archaeological site in Vietnam.

The treasure trove of artifacts was discovered at the Xom Trai archaeological site in Tan Lap commune, Lac Son district in northern Hoa Binh province, by archaeologists from the Hoa Binh Museum and the Southeast Asia Prehisory Centre.

According to VOV News, scientists said that Xom Trai Cave, recognized as a national archaeological site in 2001, is believed to be a tool workshop as well as a habitat for people of the Hoa Binh civilization.

Hundreds of stone artifacts, including seats and cutting tools, weighing up to 10 kg each, and tens of millions of seashells have been discovered in 200 sqm area in the cave.

Researchers also discovered the oldest artifact of prehistoric art in Vietnam and two ancient tracks dating back 21,000 years.

The ancient roads are the first of such discovery in Southeast Asia.

Especially, a man’s skeleton was found in a stratum of between 14,000-17,000 years old. Researchers said that the man was about 35-40 years old and 1.65-1.68 m tall.

Researchers also found two kinds of mineral rock used by prehistoric people as nutrition supplements. (ANI)

Treasure trove of stolen Afghan artifacts returned to Kabul

Washington, March 7 (ANI): Antiquities that were pillaged from more than 1,500 ancient sites around Afghanistan by scavengers, looters, and thieves, have been returned to Kabul.

Across the war-shattered nation, thieves have been pillaging antiquities from more than 1,500 ancient sites around the country and smuggling them abroad.

“It’s like a sickness that kills us slowly,” said Omara Khan Masoudi, director of the National Museum of Afghanistan. “Every day, we lose a bit more of our cultural heritage,” he told National Geographic magazine.

But now, Afghanistan is finally getting something back.

The British government, with the help of the National Geographic Society and the British Red Cross, has returned 3.4 tons of stolen antiquities that were confiscated over the past six years at London’s Heathrow Airport.

On February 17, a Red Cross freighter plane touched down at the Kabul Airport, carrying the looted treasure back to its homeland.

The artifacts are now at the National Museum.

Returning the enormous shipment took more than a year to organize, and involved the cooperation of participants from around the globe.

The Heathrow collection includes more than 1,500 objects spanning thousands of years of Afghan culture: a 3,000-year-old carved stone head from the Iron Age and hand-cast axe heads, cut rock crystal goblets, and delicate animal carvings from the Bactrian era, another thousand years earlier.

The oldest artifacts in the collection include a marble figure of an animal showing similarities to artifacts dating to the Mesolithic and Neolithic periods, dating as far back as 8,000 years.

The collection also contains gilded bronze pieces, coins, and ornately inscribed slabs dating from Afghanistan’s early Islamic period (8th-9th centuries A.D.) and treasures from the Medieval Islamic period (10th-14th centuries A.D.) that serve to replace the decimated collection at the National Museum, which was hit by a rocket in 1993 during the civil war, then repeatedly looted.

Through a quarter-century of violence, Masoudi and his staff somehow managed to save about 90 percent of the National Museum’s masterpieces, an incredible feat.

But the museum still lost about 70,000 objects, most of them from the reserve inventory kept in storage.

Helped by Carla Grissmann, an American expert on Afghan cultural heritage who has been working with the National Museum since 1973, and a British Museum curatorial team, U.S. archaeologist Fredrik Hiebert compared the objects in the Heathrow hoard to tens of thousands of missing items from the museum’s collection.

“None of the Heathrow objects came from the museum,” Hiebert said. “They are from recently illegally excavated sites exported without permit,” he added. (ANI)

The Obamas to pick their White House furniture from presidential treasure trove

Washington, January 20 (ANI): The Obama family will be allowed to select from among thousands of pieces of furniture located in a secret, 40,000-square-foot warehouse in Maryland, for use in the White House.

According to reports, the First Family will have their choice of any presidential sofa, table or chair that is still in working order.

The exact location of the warehouse has not been revealed.

Presidents and their families have dipped into the treasure trove for years.

“I remember Rosalynn Carter found in White House storage some child-size furniture that had been given to the White House during Caroline Kennedy’s time,” the Washington Times quoted former White House curator Betty Monkman as saying.

Miss Monkman, now in her early 60s, worked in the office of the White House curator from 1967 to 2002, and in 1997 was appointed chief curator.

She has helped eight presidents and their families furnish the White House during her years in the office.

According to her, the storage facility houses everything from Theodore Roosevelt-era rugs to Harry S. Truman’s bedside table.

“It’s a historic record of everything that has been used in the White House over the last 200 years,” she said.

Besides the pieces in storage, the new president also can borrow any painting from any of the national museums and hang them in either their private residence or the White House’s West Wing.

The Obamas can choose furniture for any of the 132 rooms in the White House.

If the Obamas want something more contemporary, they can buy pieces using money that Congress appropriates.

The Obamas will get a 100,000 dollars budget, and any spending on decorations beyond that will need to be financed from private sources. (ANI)

Giant bird poo records pre-historic New Zealand

Washington, Jan 13 (ANI): Scientists have found faeces from giant extinct birds, buried beneath the floor of caves and rock shelters for thousands of years in New Zealand, which reveal a treasure trove of information about the country during prehistoric times.

Jamie Wood, from the University of Otago, discovered more than 1500 faeces (coprolites) in remote areas across southern New Zealand, primarily from species of the extinct giant moa, which ranged up to 250 kilograms and three meters in height.

Some of the faeces recovered were up to 15 centimeters in length.

A team of ancient DNA and paleontology researchers from the University of Adelaide, University of Otago and the NZ Department of Conservation analyzed plant seeds, leaf fragments and DNA from the dried coprolites to start building the first detailed picture of an ecosystem dominated by giant extinct species.

“Surprisingly for such large birds, over half the plants we detected in the faeces were under 30 centimeters in height,” said Dr Wood.

“This suggests that some moa grazed on tiny herbs, in contrast to the current view of them as mainly shrub and tree browsers. We also found many plant species that are currently threatened or rare, suggesting that the extinction of the moa has impacted their ability to reproduce or disperse,” he added.

According to Professor Alan Cooper, Director of the Australian Centre for Ancient DNA, which performed the DNA typing, “New Zealand offers a unique chance to reconstruct how a ‘megafaunal ecosystem’ functioned.”

“You can’t do this elsewhere in the world because the giant species became extinct too long ago, so you don’t get such a diverse record of species and habitats,” he added.

“Critically, the interactions between animals and plants we see in the poo provides key information about the origins and background to our current environment, and predicting how it will respond to future climate change and extinctions,” he explained. (ANI)
