Secret History
Found at one sacrificial stone below a ceremonial platform called the "cuauhxicalco," the human remains date back more than 500 years and represent the largest number of skulls ever found in one offering.
Used in rituals associated with the worship of Mictlantecuhtli, god of death, the skulls were unearthed in different locations: 45 appeared to have just been dumped on top of the stone, while the remaining five were buried under it.
Each of the five skulls had holes on both sides, suggesting they belonged to a tzompantli. This was a skull rack on which the crania of sacrificed people were hung and displayed near temples or at other locations.
The Mayas played an early version of basketball in the court, using their elbows, knees and hips to knock a heavy ball through a stone ring set in the walls. The watchtower structures sat atop the low walls surrounding this ball court.
The ball court was built around 864 AD, so even though the bases of these structures had been detected before, the stairs leading to them had crumbled. All that remained of the structures was the base, or footing, which made it difficult for archaeologists to understand what their purpose was.
The Mexican government's National Institute of Anthropology and History announced that the boxes had been 90% reconstructed. A team, led by archaeologist Jose Huchim, confirmed that the sun shone through the slit-like openings on the winter solstice when the setting sun touches the horizon. The slits, which are just tall enough to stand up in, also form a diagonal pattern at the equinox.
The team knows of no other Maya ball court with such structures.

Circle of life: the Ring of Brodgar – a stone circle, or henge – is a World Heritage Site.
Drive west from Orkney's capital, Kirkwall, and then head north on the narrow B9055 and you will reach a single stone monolith that guards the entrance to a spit of land known as the Ness of Brodgar. The promontory separates the island's two largest bodies of freshwater, the Loch of Stenness and the Loch of Harray. At their furthest edges, the lochs' peaty brown water laps against fields and hills that form a natural amphitheatre; a landscape peppered with giant rings of stone, chambered cairns, ancient villages and other archaeological riches.
This is the heartland of the Neolithic North, a bleak, mysterious place that has made Orkney a magnet for archaeologists, historians and other researchers. For decades they have tramped the island measuring and ex- cavating its great Stone Age sites. The land was surveyed, mapped and known until a recent chance discovery revealed that for all their attention, scientists had completely overlooked a Neolithic treasure that utterly eclipses all others on Orkney - and in the rest of Europe.
After almost two years of restoration and preservation work, the Great Ballcourt at Chichen Itza, at 120 meters (130 yards) long the largest in Mesoamerica, is gradually recovering its original appearance with the reincorporation of different elements, including the five "passages" that the ancient Mayas built on the site.
The passages are structures that, according to recent studies, were used to observe the path of the sun during the equinoxes and solstices, INAH said in a communique.
Archaeologist Jose Huchim, coordinator of the Chichen Itza comprehensive conservation project, said that observers were possibly stationed in those structures to follow the game and see if the ball went through the vertical stone ring and make sure players hit the ball according to the rules of the ritual.
Huchim said that 25 years ago, when he was studying archaeology, he observed the site with his then-professor Victor Segovia, a pioneer in the study of pre-Colombian astronomy, because both were convinced that the passages were oriented to the equinoxes and solstices.
Archaeologists this week returned to Antikythera, the Aegean Sea island where sponge divers in 1900-1901 found the so-called Antikythera Mechanism, a remarkable 2nd-century BCE device that tracked the cycles of the solar system.
"These are unexplored sea depths beneath a trade route known since antiquity," said Angeliki Simosi, head of Greece's ephorate of underwater antiquities.
But when one 11-year-old Russian boy decided to explore his local neighborhood, he came across something which hadn't been seen in more than 100 years.
The curious youngster uncovered a nearly intact wooly mammoth - which was discovered complete with flesh, bones, fur and layers of fat.

The Moscow News reports it is a male which died about 30,000 years ago at the age of 15. It has remained frozen in permafrost ever since.

The carved alabaster vessel (shown from two sides) found in the burial chamber caused the archaeologists to conclude the tomb was that of Lady K’abel.
The tomb was revealed during digging at the ancient Maya city of El Perú-Waka' in the rain forest of northern Guatemala. Alongside the body, excavators found a white jar shaped like conch shell with the head and arm of a woman carved at the opening. The artifact had four hieroglyphs that suggest it belonged to K'abel.
"Nothing is ever proven in archaeology because we're working with circumstantial evidence. But in our case we have a carved stone alabaster jar that is named K'abel's possession," David Freidel, an archaeologist working on the site, explained in a video. Freidel, of Washington University in St. Louis, said the find is "as close to a smoking gun" as you get in archaeology.
The plazas, palaces, temple pyramids and residences of El Perú-Waka' belong to the Classic Maya civilization (200-900 A.D.). K'abel was part of a royal family and carried the title "Kaloomte'," which translates to "Supreme Warrior," meaning she had even higher in authority than her king husband, K'inich Bahlam, according to Freidel and his excavation team. K'abel is believed to have reigned with him from about 672-692 A.D.

Former president of the United States Abraham Lincoln donated money to struggling Ireland during the Great Famine
Kinealy, a Professor at Drew University in Madison, New Jersey, was rustling through the list of donations and was taken aback when she saw the name of the legendary president who donated $10 or $500 in today's financial climate.
'This was back in 1847 when Lincoln was only a newly elected politician to the House of Representatives. It was an insubstantial sum from an unimportant figure at the time but it is retrospectively very interesting,' the Trinity College graduate stated.
The 2009 winner of the Will Herberg Award for Excellence in Teaching asserts that this donation was not out of character for Lincoln, who had a lifelong rapport with the Irish.
'I suppose Lincoln always had a great affinity for the Irish and their plight. He knew and recited Robert Emmet's speech from the dock and his favourite ballad was Lady Dufferin's poem 'The Lament of the Irish Emigrant' set to music.'

The original Cairo toe, made out of wood and leather, is housed at the Egyptian Museum in Cairo. The toe was found attached to a female mummy.
One of the artifacts in question is the Greville Chester toe, now in the British Museum. It dates back before 600 B.C. and is made of cartonnage, an ancient type of papier maché made with a mixture of linen, animal glue and tinted plaster. The other is the wood and leather Cairo toe at the Egyptian Museum in Cairo, which was found on a female mummy near Luxor and is thought to date back to between 950 and 710 B.C.
If the parts were indeed used to help ancient Egyptians missing a big toe walk normally, they would be the earliest known practical prostheses - older than the bronze and wooden Roman Capua leg, which dates back to 300 B.C.
"Several experts have examined these objects and had suggested that they were the earliest prosthetic devices in existence," University of Manchester researcher Jacky Finch, who led the study, said in a statement. "There are many instances of the ancient Egyptians creating false body parts for burial but the wear plus their design both suggest they were used by people to help them to walk."
The site, known as La Bastida, was protected by 20-foot high walls and towers designed to keep its upper class residents protected and in power. The design of these structures suggests that those who built it were from Asia Minor and the Middle East.
One of the key clues to uncovering the story of La Bastida is the ogival arched postern gate, or secondary door, near the main entrance. The arch is the first one to be found in Europe from this time period, and its roots can be traced to Troy, in modern day Turkey, and urban locations in Palestine, Israel and Jordan. The construction techniques found at La Bastida would not show up in Europe until 400 to 800 years later when Mycenaeans, or city-states residents in Southern Europe, incorporated them into their military architecture.
The structure shows people from the Middle East had a hand in the construction of the fortification. The Spanish archeologists theorized the people who lived in La Bastida moved there after a mysterious crisis devastated the region 4,300 years ago. The archeological record shows the people living in Jordan and Israel at the time abandoned the safety and security of settlements for pastoral life.
