    Despite the name, there was iron in the Bronze Age. It was just extremely rare. Most famously, the pharaoh Tutankhamun had a headrest, bracelet and dagger made of iron. Other iron artifacts from the same time have also been found around the globe. The existence of these artifacts has led to an archaeological debate: was there, in fact, iron smelting in the Bronze Age? According to a new chemical analysis, the answer is no. The iron humans had during the Bronze Age came from space.

    King Tut owned a dagger that was out of this world—literally. Researchers have recently published a study in the journal Meteoritics & Planetary Science that supports what has long been suspected: The ancient Egyptians were using meteoritic iron well before the spread of iron smelting technology. The recent study on King Tut’s dagger, led by researchers from Italy and Egypt, used X-ray fluorescence (XRF) spectrometry to analyze the composition of the iron blade. Iron meteorites mostly contain iron and nickel, and the results of the XRF analysis on King Tut’s dagger confirm that the blade is mostly composed of iron...
  • Dagger in King Tut's tomb was made with iron from a meteorite

    Italian and Egyptian researchers analyzed the metal with an X-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition to known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite.

    King Tut was buried with a dagger made of an iron that literally came from space, says a new study into the composition of the iron blade from the sarcophagus of the boy king. Using non-invasive, portable X-ray fluorescence spectrometry, a team of Italian and Egyptian researchers confirmed that the iron of the dagger placed on the right thigh of King Tut's mummified body a has meteoric origin. ...

    Popular Archaeology ^ | Monday, November 17, 2014 | University of Bradford press release
    "Our evidence shows definitively that the population decline in this period cannot have been caused by climate change," says Ian Armit, Professor of Archaeology at the University of Bradford, and lead author of the study. Graeme Swindles, Associate Professor of Earth System Dynamics at the University of Leeds, added, "We found clear evidence for a rapid change in climate to much wetter conditions, which we were able to precisely pinpoint to 750BC using statistical methods." According to Professor Armit, social and economic stress is more likely to be the cause of the sudden and widespread fall in numbers. Communities producing...

    University of Birmingham via EurekAlert! ^ | October 9, 2014 | Stuart Gillespie
    Conventional estimates for the collapse of the Aegean civilization may be incorrect by up to a century, according to new radiocarbon analyses. While historical chronologies traditionally place the end of the Greek Bronze Age at around 1025 BCE, this latest research suggests a date 70 to 100 years earlier. Archaeologists from the University of Birmingham selected 60 samples of animal bones, plant remains and building timbers, excavated at Assiros in northern Greece, to be radiocarbon dated and correlated with 95.4% accuracy using Bayesian statistical methodology at the University of Oxford and the Akademie der Wissenschaften Heidelberg, Germany.

    Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, also predate the emergence of iron smelting by two millennia. Carefully hammered into thin sheets before being rolled into tubes, the nine beads – which are over 5000 years-old - were originally strung into a necklace together with other exotic minerals such as gold and gemstones, revealing the high value of this exotic material in ancient times. The study is published in the Journal of Archaeological Science....

    An ancient Buddhist statue that was recovered by a Nazi expedition in the 1930s was originally carved from a highly valuable meteorite. Researchers say the 1,000-year-old object with a swastika on its stomach is made from a rare form of iron with a high content of nickel. They believe it is part of the Chinga meteorite, which crashed about 15,000 years ago. The findings appear in the Journal, Meteoritics and Planetary Science. The 24cm (9-inch) tall statue is 10kg (22lb) and is called the Iron Man. Origins unknown The story of this priceless object owes more perhaps to an Indiana...
  • Rush for iron spurred Inuit ancestors to sprint across Arctic, book contends

    Vancouver Sun ^ | February 8, 2010 | Randy Boswell, Canwest News Service
    One of Canada's top archeologists argues in a new book that the prehistoric ancestors of this country's 55,000 Inuit probably migrated rapidly from Alaska clear across the Canadian North in just a few years -- not gradually over centuries as traditionally assumed -- after they learned about a rich supply of iron from a massive meteorite strike on Greenland's west coast. The startling theory, tentatively floated two decades ago by Canadian Museum of Civilization curator emeritus Robert McGhee, has been bolstered by recent research indicating a later and faster migration of the ancient Thule Inuit across North America's polar frontier...

    The Delhi Iron Pillar, which has withstood corrosion for over 1,600 years, continues to attract the attention of archaeologists and scientists who want to undertake a systematic study to unfold the secret behind its strength. A panel of scientists from across the country has recommended that the Government allow research on the pillar, a symbol of Indian metallurgical excellence, to ascertain its age, as well as for conservation of its underground part and the passive film that has preserved it through the ages. "The Archaeological Survey of India has agreed to allow the use of well-established non-invasive techniques to ascertain...

    Iron Age pops out of KZN sewer September 06 2002 at 11:42AM Iron Age artefacts between 50,000 and 100,000 years old were unearthed while workers were digging to lay a new sewerage pipe near Amanzimtoti on Thursday. Pieces of iron smelting furnaces, slag and iron ore, arrowheads and bits of human bone had so far been found, said Gavin Anderson of the Natal Museum in Pietermaritzburg. Once the area had been fully excavated, the artefacts would be displayed in the museum, he said. - Sapa

    the DOE and everybody in the auto industry pegged their EV hopes and dreams on lithium manganese oxide, or LMO, and lithium iron phosphate, or LFP, batteries. The reasons were simple. Both chemistries had great performance profiles for EVs and both chemistries were made using cheap and abundant raw materials – lithium, manganese and iron. The sole renegade was Tesla, which planned to use consumer grade cells and a nickel-cobalt chemistry instead of more costly automotive grade LMO and LFP cells. Tesla's theory, which had more than a touch of genius, was that using consumer grade cells would allow it...

    A perfect storm is brewing in the 21st-Century energy market, and it has nothing to do with OPEC. It’s about batteries that charge everything from mainstream electric cars to massive power walls and mountains of consumer electronics. More specifically, it’s about what goes into those batteries—and it’s not just lithium. The other element that makes up 35 percent of the lithium-ion batteries mass produced at Tesla’s (NASDAQ: TSLA) Nevada gigafactory—and at a dozen of other behemoths slated to come on line—is cobalt. And it’s already in dramatically short supply. A part of the answer to the cobalt deficit is 100...

Then, telling the 16-year-old schoolboy not to scream, they sliced off his ears. Then they pushed him down to the ground and cut off what they could of his lips. “They were all over me, stamping, pushing, cutting. I could not move, I could barely breathe,” he told The Times in a barely audible whisper from his hospital bed in the small impoverished northern Ugandan town of Kitgum. Yet the child soldiers...

    The moon is made of far more valuable stuff than green cheese. And one man wants to capitalize on that fact. NASA, which ended America's space shuttle program in June, says it wants to privatize spaceflight. Naveen Jain, co-founder and chairman of Moon Express, Inc., wants to go a step further: He wants to privatize the moon itself. Jain's company plans to piggyback on private shuttle flights, using them to carry his lunar landers and mining platforms to the moon. "People ask, why do we want to go back to the moon? Isn't it just barren soil?" Jain told FoxNews.com....

    As a child growing up in rural India in the 1960s and 1970s, Naveen Jain would gaze up at the moon and imagine a life beyond his modest surroundings. Today he's still gazing at the moon, but for far different reasons. Jain, 55, is co-founder of Moon Express, a Mountain View, Calif.-based company that's aiming to send the first commercial robotic spacecraft to the moon next year. This serial entrepreneur-he founded Internet companies Infospace and Intelius-believes that the moon holds precious metals and rare minerals that can be brought back to help address Earth's energy, health and resource challenges.
