The sad truth about uncontacted tribes

One of the world’s last isolated tribes has apparently emerged from the forest. Rachel Nuwer investigates whether there is anyone left who has never seen the outside world, and discovers that ‘first contacts’ are often cursed by death and disease.

On July 1, Funai, the Brazilian governmental agency in charge of indigenous Indian affairs, quietly posted a short press release on its website: two days earlier, they said, seven members of an isolated Indian tribe emerged from the Amazon and made peaceful contact with people in a village near the Peruvian border.
As the first official contact with such a tribe since 1996, the event was out of the ordinary. But the event itself could have been anticipated. For weeks, local villagers in Brazil’s Acre state had reported sightings of the tribesman, who supposedly came to steal crops, axes and machetes, and who “mimicked monkey cries” that frightened women and children.
The Indians’ decision to make contact was not driven by a desire for material goods, however, but by fear. With the help of translators who spoke a closely related indigenous Panoan language, the Acre Indians explained that “violent attacks” by outsiders had driven them from the forest. Later, details emerged that their elder relatives were massacred, and their houses set on fire. Illegal loggers and cocaine traffickers in Peru, where the Indians are thought to come from, are likely to blame, according to the Brazilian government. Indeed, Funai’s own nearby monitoring post was shut down in 2011 due to increasing escalations with drug traffickers.

After they decided the situation called for drastic measures, the Indians did not just stumble upon the Brazilian village by chance – they probably knew exactly where to go. “They know far more about the outside world than most people think,” says Fiona Watson, research director for the non-profit organisation Survival International. “They are experts at living in the forest and are well aware of the presence of outsiders.”
This gets to the heart of a common misconception surrounding isolated tribes such as the one in Acre: that they live in a bubble of wilderness, somehow missing the fact that their small corner of the world is in fact part of a much greater whole – and one that is dominated by other humans. “Almost all human communities have been in some contact with one another for as long as we have historical or archaeological records,” says Alex Golub, an anthropologist at the University of Hawaii at Manoa. “Human prehistory is not like that game Civilization where you start with a little hut and the whole map is black.”
In some cases in the 70s and 80s, the Brazilian government did try to establish peaceful contact with indigenous people, often with the aim of forced assimilation or relocation. They set up “attraction posts” – offerings of metal tools and other things indigenous Indians might find to be valuable – to try and lure them out of hiding. This sometimes led to violent altercations, or, more often than not, disease outbreaks. Isolated people have no immunity to some bugs, which have been known to wipe out up to half of a village’s population in a matter of weeks or months. During those years, missionaries traipsing into the jungle also delivered viruses and bacteria along with Bibles, killing the people they meant to save.

   Silicon: After the chip, another revolution?

Summer is upon us and you are almost certainly planning at least one trip to the beach. This year, as you lie back in the sun, put down your book or magazine and sift the sand through your fingers - and take a moment to reflect upon how much of the world economy is built on the stuff.
I don't mean "built on sand" in a philosophical sense, however true that may be. I'm talking about three technological revolutions that are literally based on sand, one of which is only just beginning and, if it lives up to its potential, has mind-boggling implications.
You've probably already guessed the element at the heart of these revolutions - silicon, the main component of sand.
The original silicon revolution was of course, glass. Man first began to explore its properties a million and a half years ago - that's when our ancient ancestors discovered that obsidian, the almost jet black glass which is sometimes formed when lava cools rapidly, was useful.
Obsidian breaks leaving a very keen edge, so was good for weapons and tools including, in some ancient cultures, knives used for ritual circumcisions.
But it wasn't until the first civilizations arose in the plains of Mesopotamia that we learned to actually make glass.Obsidian tool

The French spy who wrote The Planet of the Apes

Pierre Boulle
Before the newly released Dawn of the Planet of the Apes film, there was a long franchise going back to the first Apes movie - the 1968 classic with Charlton Heston. But before that there was the book.
Today few people have heard of Pierre Boulle. He was the French author who first had the brilliant idea of humans travelling in time and stumbling on ape civilisation. It was in his 1963 novel La Planete des Singes (Planet of the Apes).
But there's more. It turns out that Pierre Boulle was also the man behind another cinema great - none other than The Bridge on the River Kwai. A book on the face of it so quintessentially British - about a British colonel and his conception of duty and honour. How on earth could it have been written by a Frenchman? And how did that same Frenchman then move from wartime adventure to the world of science fiction for his second Hollywood triumph?
Pierre Boulle died in Paris in 1994, after a writing career that spanned more than 40 years and resulted in some 30 novels and collections of short stories.
But it was his life before taking up the pen that shaped his literary outlook. From the mid-1930s he was a rubber planter for a British company in Malaysia. And in World War Two he served as an undercover agent for the Special Operations Executive (SOE).
For The Bridge on the River Kwai he was writing of a world he knew well.

"Pierre Boulle was profoundly Anglophile," says Jean Loriot, who heads the Association of Friends of Pierre Boulle.
"In the Far East he worked alongside English people. He was impregnated by English culture. He admired the English greatly. And when he came to write he made many of his heroes English."

Siberia (2)



Siberian Craters

The Really Scary Thing About Those Jaw-Dropping Siberian Craters

 Russian scientists have determined that a massive crater discovered in a remote part of Siberia was probably caused by thawing permafrost. The crater is in the Yamal Peninsula, which means “end of the world.” It caught hold of the media spotlight in mid-July when it was spotted by oil and gas workers flying over the area. At roughly 200 feet wide and seemingly bottomless, speculation abounded about the cause with the Siberian Times reporting that, “theories range from meteorites, stray missiles, a man-made prank, and aliens, to an explosive cocktail of methane or shale gas suddenly exploding.”

Schaefer said the phenomenon of the Siberian craters was a surprise to him because he thought the methane would leak out more slowly. Capturing these large bursts of methane before they enter the atmosphere could be possible, according to Schaefer, however extremely difficult.
“The key is drilling into the permafrost before the methane escapes,” he said. “However, creating the infrastructure just to get to these remote locations is daunting.”
He said that capturing the emissions from decaying organic matter would be impossible.
Ted Schuur, a professor of ecosystem ecology at the University of Florida and leader of the Permafrost Carbon Network, told ThinkProgress that the Siberian craters remind him of ‘hot spots’ of methane bubbling that occur both in lakes and undersea in the permafrost zone.
