Oldest Water On Earth Found

I remember an episode of Dr. Who where they found really old water at the core of a planet.  As I recall, that did not go that well…

Oldest Water on Earth Found Deep Underground

The finding suggests ancient life might be found within Earth and on Mars

A pocket of water some 2.6 billion years old – the most ancient pocket of water known by far, older even than the dawn of multicellular life – has now been discovered in a mine 2 miles below the Earth’s surface.

The finding, announced in the May 16 issue of the journal Nature, raises the tantalizing possibility that ancient life might be found deep underground not only within Earth, but insimilar oases that may exist on Mars, the scientists who studied the water said.

Geoscientist Barbara Sherwood Lollar at the University of Toronto and her colleagues have investigated deep mines across the world since the 1980s. Water can flow into fractures in rocks and become isolated deep in the crust for many years, serving as a time capsule of what their environments were like at the time they were sealed off.

In gold mines in South Africa 1.7 miles (2.8 kilometers) deep, the scientists previouslydiscovered microbes could survive in pockets of water isolated for tens of millions of years. These reservoirs were many times saltier than seawater, “and had chemistry in many ways similar to hydrothermal vents on the bottom of the ocean, full of dissolved hydrogen and other chemicals capable of supporting life,” Sherwood Lollar said.

To see what other ancient pockets of water might exist, Sherwood Lollar and her colleagues investigated copper and zinc mines near the city of Timmins in Ontario, Canada. “As the prices of copper, zinc and gold have gone up, mines now go deeper, which has helped our search for long-isolated reservoirs of water hidden underground,” Sherwood Lollar said.

‘Mind-blowing’ find

“Sometimes we went down in cages – they’re not called elevators underground – that dropped us to the levels we wanted to go,” Sherwood Lollar told OurAmazingPlanet. “Other times, we went down ramp mines, which have curling spiral roadways, so we could actually drive all the way down.”

The scientists analyzed water they found 2 miles deep. They focused on noble gases such as helium, neon, argon and xenon. Past studies analyzing bubbles of air trapped within ancient rocks found that these rare gases could occur in distinct ratios linked with certain eras of Earth’s history. As such, by analyzing the ratios of noble gases seen in this water, the researchers could deduce the age of the water.

The scientists discovered the fluids were trapped in the rocks between 1.5 billion and 2.64 billion years ago.

“It was absolutely mind-blowing,” Sherwood Lollar said. “These weren’t tens of millions of years old like we might have expected, or even hundreds of millions of years old. They were billions of years old.”

The site was formed by geological activity similar to that seen in hydrothermal vents. “We walked along what used to be ocean floor 2.7 billion years ago,” Sherwood Lollar said. “You could still see some of the same pillow lava structures now seen on the bottom of the ocean.”

Signs of life?

This ancient water poured out of the boreholes the team drilled in the mine at the rate of nearly a half-gallon per minute. It remains uncertain precisely how large this reservoir of water is.

“This is an extremely important question and one that we want to pursue in our future work,” Sherwood Lollar said. “We also want to see if there are habitable reservoirs of similar age around the world.”

Sherwood Lollar emphasized they have not yet found any signs of life in the water from Timmins. “We’re working on that right now,” she said. “It’d be fascinating to us if we did, since it’d push back the frontiers of how long life could survive in isolation.”

And the implications of such a finding would extend beyond the extremes of life on Earth.

“Finding life in this energy-rich water is especially exciting if one thinks of Mars, where there might be water of similar age and mineralogy under the surface,” Sherwood Lollar said.

If any life once arose on Mars billions of years ago as it did on Earth, “then it is likely in the subsurface,” Sherwood Lollar said. “If we find the water in Timmins can support life, maybe the same might hold true for Mars as well.”

Ancient Shoes Found In Egypt

Lost and found: Ancient shoes turn up in Egypt temple

More than 2,000 years ago, at a time when Egypt was ruled by a dynasty of kings of Greek descent, someone, perhaps a group of people, hid away some of the most valuable possessions they had — their shoes.

Seven shoes were deposited in a jar in an Egyptian temple in Luxor, three pairs and a single one. Two pairs were originally worn by children and were only about 7 inches long. Using palm fiber string, the child shoes were tied together within the single shoe (it was larger and meant for an adult) and put in the jar. Another pair of shoes, more than 9 inches long that had been worn by a limping adult, was also inserted in the jar.

The shoe-filled jar, along with two other jars, had been “deliberately placed in a small space between two mudbrick walls,” writes archaeologist Angelo Sesana in a report published in the journal Memnonia.

‘The shoes were in pristine condition and still supple upon discovery.’

– André Veldmeijer, an expert in ancient Egyptian footwear 

In 2004, an Italian archaeological expedition team, led by Sesana, rediscovered the shoes. The archaeologists gave André Veldmeijer, an expert in ancient Egyptian footwear, access to photographs that show the finds.

“The find is extraordinary as the shoes were in pristine condition and still supple upon discovery,” writes Veldmeijer in the most recent edition of the Journal of the American Research Center in Egypt. Unfortunately after being unearthed the shoes became brittle and “extremely fragile,” he added.

Pricey shoes
Veldmeijer’s analysis suggests the shoes may have been foreign-made and were “relatively expensive.” Sandals were the more common footwear in Egypt and that the style and quality of these seven shoes was such that “everybody would look at you,” and “it would give you much more status because you had these expensive pair of shoes,” said Veldmeijer, assistant director for Egyptology of the Netherlands-Flemish Institute in Cairo.

The date of the shoes is based on the jar they were found in and the other two jars, as well as the stratigraphy, or layering of sediments, of the area. It may be possible in the future to carbon date the shoes to confirm their age.

Why they were left in the temple in antiquity and not retrieved is a mystery. “There’s no reason to store them without having the intention of getting them back at some point,” Veldmeijer said in an interview with LiveScience, adding that there could have been some kind of unrest that forced the owners of the shoes to deposit them and flee hastily. The temple itself predates the shoes by more than 1,000 years and was originally built for pharaoh Amenhotep II (1424-1398 B.C.).

Design discoveries
Veldmeijer made a number of shoe design discoveries. He found that the people who wore the seven shoes would have tied them using what researchers call “tailed toggles.” Leather strips at the top of the shoes would form knots that would be passed through openings to close the shoes. After they were closed a long strip of leather would have hung down, decoratively, at either side. The shoes are made out of leather, which is likely bovine.

Most surprising was that the isolated shoe had what shoemakers call a “rand,” a device that until now was thought to have been first used in medieval Europe. A rand is a folded leather strip that would go between the sole of the shoe and the upper part, reinforcing the stitching as the “the upper is very prone to tear apart at the stitch holes,” he explained. The device would’ve been useful in muddy weather when shoes are under pressure, as it makes the seam much more resistant to water.

In the dry (and generally not muddy) climate of ancient Egypt, he said that it’s a surprising innovation and seems to indicate the seven shoes were constructed somewhere abroad.

Health discoveries
The shoes also provided insight into the health of the people wearing them. In the case of the isolated shoe, he found a “semi-circular protruding area” that could be a sign of a condition called Hallux Valgus, more popularly known as a bunion. [The 9 Most Bizarre Medical Conditions]

“In this condition, the big toe starts to deviate inward towards the other toes,” Veldmeijer writes in the journal article. “Although hereditary, it can also develop as a result of close fitting shoes, although other scholars dispute this ….”

Another curious find came from the pair of adult shoes. He found that the left shoe had more patches and evidence of repair than the shoe on the right. “The shoe was exposed to unequal pressure,” he said, showing that the person who wore it “walked with a limp, otherwise the wear would have been far more equal.”

Still, despite their medical problems, and the wear and tear on the shoes, the people who wore them were careful to keep up with repairs, Veldmeijer said. They did not throw them away like modern-day Westerners tend to do with old running shoes.

“These shoes were highly prized commodities.”

Veldmeijer hopes to have the opportunity to examine the shoes, now under the care of the Ministry of State for Antiquities, firsthand.

Brain Remover Found – No Not Jersey Shore…

A brain remover was found.  No, not Jersey Shore, or Baby Boo-Boo, this one is from ancient Egypt, and made of wood, not poorly cast fake reality shows.

Mummy Brain: Gray Matter-Removal Tool Found In Ancient Egyptian Skull

A brain-removal tool used by ancient Egyptian embalmers has been discovered lodged in the skull of a female mummy that dates back around 2,400 years.

Removal of the brain was an Egyptian mummification procedure that became popular around 3,500 years ago and remained in use in later periods.

Identifying the ancient tools embalmers used for brain removal is difficult, and researchers note this is only the second time that such a tool has been reported within a mummy’s skull.

The discovery

Located between the left parietal bone and the back of the skull, which had been filled with resin, the object was discovered in 2008 through a series of CT scans. Researchers then inserted an endoscope (a thin tube often used for noninvasive medical procedures) into the mummy to get a closer look and ultimately detach it from resin to which it had gotten stuck.  [See Photos of Mummy & Brain-Removal Tool]

The object, which measures 3 inches (8 cm) in length, was cut off from resin that it had gotten stuck to (hence the jagged edge). Made of a species Monocotyledon plant, it would have been used to remove the mummy’s brain.

“We cut it with a clamp through the endoscope and then removed it from the skull,” said lead researcher Dr. Mislav Čavka, of the University Hospital Dubrava in Zagreb Croatia, in an interview with LiveScience.

They found themselves peering at an object more than 3 inches (8 centimeters) long that would have been used for liquefying and removing the brain. “It almost definitely would have been used in excerebration [brain removal] of the mummy,” Čavka said.

The instrument would have been inserted through a hole punched into the ethmoid bone near the nose. “Some parts [of the brain] would be wrapped around this stick and pulled out, and the other parts would be liquefied,” Čavka said.

The Egyptian mummy could then be put on its abdomen and the liquid drained through the nose hole. “It is an error that [the] embalmers left this stick in the skull,” said Čavka, adding the tool may have broken apart during the procedure.

This embalming accident, unfortunate for the ancient mummy, has provided researchers with a very rare artifact. Čavka’s team point out in a paper they published recently in the journal RSNA RadioGraphics the only other brain-removal stick found inside a mummy’s skull dates back 2,200 years.

When the object was first discovered researchers were not sure what it was. So they inserted an endoscope (a thin tube used for non-invasive medical procedures) into the mummy to get a closer look.

“Probably in museums in Egypt there are many other evidences, but they were not found inside the skull,” making it tricky to identify such artifacts as brain-removal tools, said Čavka.

The mummy is currently in the Archaeological Museum in Zagreb Croatia and is that of a woman who died around the age of 40. Brought to Croatia in the 19th century without a coffin, it’s not known where she was found in Egypt. Radiocarbon dating and CT scans of the mummy determined its date to be around 2,400 years. Her cause of death is unknown.

New insights

The stick is quite brittle and the team could not do as thorough of an analysis as they’d hoped. Looking at it under a microscope, botanical experts determined the tool is made from plants in the group Monocotyledon, which includes forms of palm and bamboo.

brain removal tool
CT scans of a 2,400-year-old female mummy revealed a tubular object embedded in its skull between the brain’s left parietal bone and the resin filled back of the skull. It would turn out to be a tool used for the removal of the brain.

The most curious find came when the researchers compared their discovery with an ancient account of brain removal made by the Greek writer Herodotus in the fifth century B.C. A visitor to Egypt, he had this to say about how Egyptian brain removal worked (as translated by A. D. Godley, Cambridge, Harvard University Press, 1920, through Perseus Digital Library):

“Having agreed on a price, the bearers go away, and the workmen, left alone in their place, embalm the body. If they do this in the most perfect way, they first draw out part of the brain through the nostrils with an iron hook, and inject certain drugs into the rest.”

The recent discovery suggests an organic stick, not an “iron hook,” was used in at least some of these procedures, possibly for economic reasons. Researchers note that the tool found in the skull of the other mummy, dating from 2,200 years ago, was also made of an organic material.

“It is known that mummification was widely practiced throughout ancient Egyptian civilization, but it was a time-consuming and costly practice. Thus, not every­one could afford to perform the same mummifi­cation procedure,” write the researchers in their journal article.
