Scientists have discovered the remains of three humans – including a child-of-three – that appear to have been killed for food, their bodies butchered and then eaten.
The bones showed precision cuts to extract the maximum amount of meat and the skulls had been carved into cups and bowls for drinking and eating.
The fragments – which are 14,700 years old- are thought to be the oldest examples in the world of skull cups and the first evidence of ritual killing in Britain.
What is particularly horrific is that at the time, humans knew how to bury their dead and so were not savages meaning the remains are most likely the result of premeditated cannibalism.
"At the time life was very tough," said Professor Chris Stringer, a palaeontologist at the Natural History Museum, who helped excavate the skull cups.
"Cannibalism would have been a good way of removing groups competing with you and getting food for yourself.
"There was also a feeling that if you ate your enemy you gained some of his power."
At the time Britain was just emerging from the Ice Age and the cavemen – believed to be Cro Magnons originally from France – would have come to Britain from the Netherlands in summer, probably following animal herds migrating across land that is now the North Sea.
Just a few hundred strong, the hunter gatherers would have mainly lived off reindeer and horses but when times got tough it is believed they would have fought and eaten competing groups.
Prof Stringer said they were not savages and knew exactly what they were doing.
"What is more sinister is that these were quite sophisticated hunter gatherers – very like us," said Prof Stringer.
"They could make tools and painted cave art. They also had quite complex burials for the people they were not eating, treating the dead with reverence.
No one can be sure, exactly what happened but the three cadavers, found in Gough's Cave, Somerset, show signs of being chopped up for food.
The 41 pieces of bone, found in 1987 but only just fully analysed, were broken up to remove the marrow and cut marks shows that they were meticulously cleaned to remove all the soft tissues.
Most gruesomely the skulls were shown to have been smashed into cups, the hair scalped from the head, and the tongues and eyes gouged out.
The sharp edges were also cleaned up so that they could be used a drinking cup perhaps to consume "blood, wine or food" during the meal.
But once the feast had been finished the scientists believe that the cannibals discarded the bones and the skull cups and moved on.

The Church Of Scientology, Fact-Checked
“Lawrence Wright’s cover story in the current edition of The New Yorker reports on the Church of Scientology and focuses on why screenwriter and director Paul Haggis resigned from the organization in 2009 after spending nearly 35 years with it.
Haggis, who directed Crash and wrote the screenplay for Million Dollar Baby, spoke with Wright about his reasons for leaving the church and the response from his fellow Scientologists.
Wright tells Fresh Air’s Terry Gross about the detailed fact-checking process his article went through — The New Yorker assigned five fact checkers to the story and sent the Church of Scientology 971 fact-checking queries before publication.
In September 2010, Wright, his editor, the New Yorker fact-checking team and the magazine’s editor-in-chief, David Remnick, met for eight hours with the spokesman for the Church of Scientology, Tommy Davis, along with Davis’ wife and four lawyers representing the church, to discuss the facts in the piece.
Wright says that one of the most interesting parts of the meeting came when he asked Davis about L. Ron Hubbard’s medical records. Hubbard, the founder of Scientology, had maintained that he was blind and a ‘hopeless cripple’ at the end of World War II — and that he had healed himself through measures that later became the basis of Dianetics, the 1950 book that became the basis for Scientology.
“I had found evidence that Hubbard was never actually injured during the war. … And so we pressed [Tommy Davis] for evidence that there had been such injuries and [Hubbard] had been the war hero that he described,” says Wright. “Eventually, Davis sent us what is called a notice of separation — essentially discharge papers from World War II — along with some photographs of all of these medals that [Hubbard] had won. … At the same time, we finally gained access to Hubbard’s entire World War II records [through a request to the military archives] and there was no evidence that he had ever been wounded in battle or distinguished himself in any way during the war. We also found another notice of separation which was strikingly different than the one that the church had provided.”"

The more you lie, the easier it gets
“Our brains are naturally better at telling the truth than lying, but repeated lying can overcome our tendency for veracity, making subsequent lying easier – and possibly undetectable.
Neuroimaging studies have shown that people’s brains show considerably more activity when they are lying than when they are not, particularly in the prefrontal cortex, suggesting that lying requires extra cognitive control and inhibition of truth-telling. Lying also takes measurably longer than telling the truth.
To test whether the brain’s so-called “dominant truth response” can be changed, Bruno Verschuere of Ghent University in Ghent, Belgium, and colleagues studied three groups of students.
True or false?
The students were first asked to provide a written report about their daily activities. Each student was then questioned about these activities, and asked to either lie or tell the truth in their answers.
Interspersed with these questions were “filler” questions on a new topic. One group was always asked to tell the truth to the filler questions, a second group had to lie, and a third group was asked to lie or tell the truth in equal measure.
The researchers found that the frequent liars became more adept at lying. The normal difference in reaction times between telling the truth and lying disappeared.”

Are Shrinking Brains Making Us Smarter?
“Human brains have shrunk over the past 30,000 years, puzzling scientists who argue it is not a sign we are growing dumber but that evolution is making the key motor leaner and more efficient.
The average size of modern humans — Homo sapiens — has decreased about 10 percent during that period — from 1,500 to 1,359 cubic centimeters (91 to 83 cubic inches), the size of a tennis ball.
Women’s brains, which are smaller on average than those of men, have experienced an equivalent drop in size.
These measurements were taken using skulls found in Europe, the Middle East and Asia.
“I’d called that a major downsizing in an evolutionary eye blink,” John Hawks of the University of Michigan told Discover magazine.
But other anthropologists note that brain shrinkage is not very surprising since the stronger and larger we are, the more gray matter we need to control this larger mass.
The Neanderthal, a cousin of the modern human who disappeared about 30 millennia ago for still unknown reasons, was far more massive and had a larger brain.
The Cro-Magnons who left cave paintings of large animals in the monumental Lascaux cave over 17,000 years ago were the Homo sapiens with the biggest brain. They were also stronger than their modern descendants.
Psychology professor David Geary of the University of Missouri said these traits were necessary to survive in a hostile environment.
He has studied the evolution of skull sizes 1.9 million to 10,000 years old as our ancestors and cousins lived in an increasingly complex social environment.”

Mummies' false toes put a spring in amputees' step
Egyptologist Jacky Finch has a thing for toes – specifically, ancient artificial toes that she believes are the earliest known prostheses. Finch's fetish motivated her to try something no one has ever done before: she recreated these unusual artifacts, strapped them to living volunteers and demonstrated that they could indeed have functioned as surrogate digits.
Her work suggests that prosthetic medicine took its first steps a few hundred years earlier than previously thought.
While studying man-made body parts found on Egyptian mummies, Finch, a researcher at the University of Manchester in the UK, stumbled on the two false big toes on which her latest research rests.
One, called the Greville Chester toe, was found near Luxor, Egypt. It was crafted some time before 600 BC from cartonnage – a kind of papier mâché made of linen and animal glue and covered in tinted plaster. The toe even includes an indentation that likely held an ornamental toenail.
The other belonged to a priest's daughter named Tabaketenmut, who lived sometime between 950 and 710 BC. If Tabaketenmut had diabetes, as some researchers have suggested, she may have lost her toe to ischaemic gangrene. Her prosthesis (shown above) is an elaborate three-piece construction of wood and what Finch thinks is leather, complete with a hinge that might mimic the flexibility of the joints.
Both artificial toes had holes for lacings that likely secured them to the feet.

Pasta-Shaped Light from Spinning Black Holes Could Challenge Einstein
“For relativity, it’s very important,” said physicist Martin Bojowald at Penn State University, who was not involved in the new work. “There are very few classic tests of relativity. It now seems that we are pretty close to actually using this.”
Black holes are greedy beasts. Not only do they attract matter so strongly that even light can get trapped in their great gravitational bellies, they also grab hold of the fabric of space-time in their vicinity. When a black hole spins — and astronomers expect that most do, although none have been definitively observed — it swirls its surrounding space-time around with it like water spiraling around a drain.
This phenomenon, called frame-dragging, has been proven to work even around bodies as small as Earth. Observations of two Earth-orbiting satellites over the last few decades show that the satellites drag by several feet per year as Earth’s spin tows the fabric of space and time in circles.
“If you can see it, such a tiny little effect from this minute mass that the Earth has compared to a black hole, how much easier would it be to see it around a black hole?” said space physicist Bo Thidé of the Swedish Institute of Space Physics, coauthor of a paper published online February 13 in Nature Physics. “That’s how we started.”
From other researchers’ experiments using lasers and lenses, Thidé and colleagues knew that light traveling in a straight line can be forced into a spiral if sent through the right kind of lens. The twisted beams come out looking like corkscrew-shaped fusilli pasta, Thidé says.

King Tut Statues Stolen From Egypt Museum
According to Zahi Hawass, who under Mubarak was recently named minister of antiquities, some 18 objects went missing following a break-in at the museum on Jan. 28, 2011.
"The staff of the database department at the Egyptian Museum, Cairo, have given me their report on the inventory of objects at the museum following the break in. Sadly, they have discovered objects are missing from the museum," Hawass wrote in his blog.
The artifacts include a limestone statue of Akhenaten holding an offering table (previously announced to have been under restoration), and two gilded wood statues of King Tutankhamun, one of the boy king being carried by a goddess, the other of the pharaoh harpooning.
"Only the torso and upper limbs of the king are missing from this object," Hawass said, referring to the harpooning statue.
The other artifacts are a statue of Queen Nefertiti making an offering, the sandstone head of an Amarna princess, a stone statuette of a scribe from Amarna, and 11 wooden statuettes plus a heart scarab (a protective amulet for the heart) belonging to Yuya, King Tut's great-grandfather.
Hawass stated that an investigation has begun to find the people who have taken the objects, with the police and army planning to follow up with criminals already in custody.
He added that "in another terrible turn of events, on the night of 11 February, 2011 a magazine in Dahshur was broken into."
Called called De Morgan's, the magazine contains large blocks and small artifacts.
"I have said if the Egyptian Museum is safe, then Egypt is safe. However, I am now concerned Egypt is not safe," Hawass said.
Egyptologists and archaeologists have reacted with sadness and disconcert to the announcement, which comes after a series of reassuring statements.
"Just a few days ago it was stated that the museum was safe and everything could be easily restored. Now official sources say that some priceless artifacts have been stolen and others are impossible to restore," Daniele Salvoldi, a doctoral candidate in Egyptology at the University of Pisa, Italy, told Discovery News.

World’s Total CPU Power: One Human Brain
The trends they spot range from the expected—Internet access has pushed both analog and digital phones into a tiny niche—to the surprising, such as the fact that, in aggregate, gaming hardware has always had more computing power than the world’s supercomputers.
The authors were remarkably thorough. For storage media, they considered things like paper, film, and vinyl records, and such modern innovations as Blu-ray discs and memory cards. To standardize their measurements across media, they used Shannon’s information theory to consider data storage in terms of optimally compressed bits. They also tracked technology, noting that in the year 2000, bits of video were compressed using cinepak, which was far less efficient than the current MPEG-4 format; calculations were adjusted accordingly.
Even so, there are some significant estimations here. “For example,” the authors note, “after normalization on optimally compressed bits we can say things like ‘a 6 square-cm newspaper image is worth a 1,000 words.’”
Similar sorts of estimates are required for things like broadcast capability and two-way communications, both of which are compiled as bits-per-second figures. The researchers estimate typical consumption of broadcast media to figure out how much of the existing capacity is used, and they figure that, since telecom equipment is run to maximize the use of its capacity, it’s usually booked to close to its limit.

Everything You Wanted to Know About Dinosaur Sex Read
How did these dinosaurs—bristling with spikes and plates—go about making more dinosaurs without skewering each other?
Stegosaurus has become an icon of the mystery surrounding dinosaur sex. Dinosaurs must have mated, but just how they did so has puzzled paleontologists for more than 100 years. Lacking much hard evidence, scientists have come up with all kinds of speculations: In his 1906 paper describing Tyrannosaurus rex, for instance, paleontologist Henry Fairfield Osborn proposed that male tyrant dinosaurs used their minuscule arms for “grasping during copulation.” Others forwarded similar notions about the function of the thumb-spikes on Iguanodon hands. These ideas eventually fell out of favor—perhaps due to embarrassment as much as anything else—but the question remained. How can we study the sex lives of animals that have been dead for millions upon millions of years?
