Six months is all it took to flip Europe’s climate from warm and sunny into the last ice age, researchers have found.

They have discovered that the northern hemisphere was plunged into a big freeze 12,800 years ago by a sudden slowdown of the Gulf Stream that allowed ice to spread hundreds of miles southwards from the Arctic.

Previous research had suggested the change might have taken place over a longer period — perhaps about 10 years.

The new description, reminiscent of the Hollywood blockbuster The Day After Tomorrow, emerged from one of the most painstaking studies of past climate changes yet attempted.

Once again, I hear the siren song of Toxoplasma, the parasite that dwells in the brains of 50 million Americans.

Toxoplasma gondii is an extraordinary creature. (…) This single-celled organism has a life cycle that takes it from cats to other mammals and birds and back to cats again. Studies have shown that the parasite can alter the behavior of rats, robbing them of their normal fear of cats–and presumably making it easier for the parasites to get into their next host.

Toxoplasma is astonishingly successful, able to live in thousands of species, including us. Billions of people are infected with Toxoplasma, which they pick up from the soil or from contaminated meat or water. In most people it remains dormant, but even in this quiet state it may also have affect human behavior. Some scientists have linked Toxoplasma to schizophrenia, while others have found personality differences between people with Toxoplasma and those who are Toxo-free. It’s possible that it uses its prey-altering strategy on our brains, too.

All well and good. But now Toxplasma is going big time. Today the Proceedings of the Royal Society of London is publishing a paper called, “Can the common brain parasite, Toxoplasma gondii, influence human culture?”
The paper’s answer? Quite possibly yes.

A shrunken head is a human head that has been prepared for ritual use or trade.

Most known shrunken heads were manufactured either by indigenous peoples in Melanesia and the Amazon Basin, or by European or Euro-Americans attempting to recreate the practice. In Amazonia, the only people known to have shrunk human heads are the Shuar, Achuar, Huambisa and Aguaruna, collectively classified as the Jivaroan peoples of Ecuador and Peru. Among the Shuar, a shrunken head is known as a tsantsa.

By the end of the nineteenth century, little was still known about the Jivaro Indian clans in South America, except for their macabre practices of taking the heads of their enemies. This practice intrigued travelers and collectors and compelled them to visit these tribes to satisfy their curiosity.

The visits of the white man helped revolutionize the Jivaro’s methods of warfare, as they began trading firearms and ammunition for shrunken human heads. (…)

In the 1930s heads were made to order and sold for approximately $25.00.

{ Goya, Plate 39 from The Disasters of War, 1810-1820 }

{ Jake and Dinos Chapman, Great Deeds Against the Dead, 1994 }

The Chapman brothers, fresh out of the Royal College of Art, had become obsessed with Goya’s gory ouvre - to the point, as Jake Chapman told me in a phone interview, that they later even considered changing their surname to Goya. They were especially haunted by the famous series of etchings known as “The Disasters of War”, in which Goya portrayed the atrocities he had witnessed in the Peninsular War between Spain and France (1808-1814) with a visceral horror. (…)

In 1994, they re-created plate 39 of “The Disasters of War - Great Feat! With Dead Men!” - on a larger scale, using nylon-wigged mannequins. Great Deeds Against the Dead (1994), which was their contribution to the legendary ‘Sensation’ exhibition at the Royal Academy, depicts three naked male bodies bound to a tree; blood dribbles from the crotches of these shop dummies where their genitalia would have been, if they’d ever had them. One victim’s arm dangles by its fingers from the makeshift gallows alongside the carcass of his torso, the severed head skewered on a branch.

With their bronze sculptures under the title “Sex” (2003), the Chapman brothers make a jump in time. They show the decomposed corpses from “Great Deeds Against the Dead” (1994). The bodies are swarming with flies, maggots, worms, and all sorts of creatures which have picked their bones clean. At first glance, everything seems naturalistic. It isn’t until one examines the work more closely and talks to the artists that one realizes the flies and worms were originally cheap plastic reproductions from toy stores and novelty shops. These were cast in bronze and hand-painted by the artists.
