It Just Ain’t Natural!
Here's a quick round-up of a few things that I couldn't quite crow-bar into the "Weird Wildlife" category.If you've any particular aversion to rats, and quite a lot of people have, then Deshnok in India is probably a place best avoided, for there stands the Karni Mata Temple, built a century ago and devoted to the Hindu matriarch Karni Mata. Worshipped as a 14th century incarnation of the goddess Durga, Karni Mata is said to have struck a deal with Yama, the god of death, that all members of her clan would reincarnate as rats so that the clan would remain united. Hence rats in Deshnok are sacred animals, venerated as ancestors, and fed and protected by the locals, so than now thousands of rats scamper over the feet of visitors to the temple (National Geographic).
And it's not only in India that people have built havens for rats, one was once built in British Columbia, though for quite a different reason. Bruce Alexander was studying addiction, and he had a problem. He knew that rats kept in cramped cages or strapped to apparatus that allowed them to dose themselves with drugs, would often do so to the point of self-destruction, but, he thought, could you really blame them? What if the addiction to the drugs was a product of their environment, rather than a reaction to the drug itself? Hence, in the 1970s, Alexander decided to give his rats the best living conditions he could, so he build "Rat Park". It was 95 square-feet in area, and well stocked with food, toys and "private areas" where the rats - who would be of both sexes - could go to mate or give birth. It was then filled with rats who had been forced to consume morphine for 8 weeks prior to the experiment, quite long enough to cause hopeless addiction in standard experiments, who were now offered a choice of pure water, or more morphine. All of them chose water. Nothing Alexander could do would entice them to take the drug, even sweetening it had no effect, only when he added naloxone (a drug that blocks the action of opiates) or diluted the morphine to the point of near impotency, could park rats be tempted to take it (Absolute Astronomy).
Yet another piece of rodent research now, as scientists (sadly not from NIMH) have found that transplanting a human 'language gene' into mice affects the way they communicate with one another. The gene, called foxp2 is one of a small family of genes known to be markedly different in humans compared to apes and other animals, hence may be the genes that are the very core of our humanity, so would putting a humanized gene in a mouse create a talking mouse? Well, no, there's a lot more to our use of language than a single gene, however while the transgenic mice were significantly less curious, they also showed increased growth and plasticity in the speech centres of their brains, and a tendency to use a greater range of frequencies in their calls (NY Times).

Eyeborg
Rob Spence, a filmmaker in Canada, who lost his right eye has now replaced that eye with a camera. Engineer Kosta Grammatis designed a video camera and transmitter that would fit into a prosthetic eye. Just think of all the possibilities. Waring: video does contain a very brief scene of eye surgery in the beginning. EyeborgEyeborg Phase II from eyeborg on Vimeo.

Artificial Blitzkriegs
I came across a description of this experiment in an old newspaper (Reno Evening Gazette, Sep 8, 1941) and have never found any other references to it. The experiment was conducted by British psychologists who wanted to find out if "civilian populations can be made immune, through familiarity, to fear caused by air raid noises." The methodological problems with the design of the experiment are obvious, but it's interesting that it was conducted nevertheless. The details follow:The London experiment consisted of herding workers, children and bomb-shocked neurotics into underground vaults and there subjecting them to an 'artificial blitz bombing.'
Sound effects used in the test were recordings made during one of London's worst air raids last year, amplified to simulate the real thing. An Associated Press writer who witnessed the experiment reported:
"The sounds swelled in the dark vault. The guns kept banging. Then big bombs burst. The guns kept up. More bombs. Then the crackle of flames. Next clanging fire engines added their noise, the other sounds continuing."
According to the reporter, the subjects stood the test very well: 'No one was crying out. A flashlight swung around the room, revealing drawn faces and frightened eyes. But no one was swooning. The experimenters stepped up the amplification.'
The British psychologists responsible for the experiment were reported delighted with the results. They said it proved their theory that whole populations could be exposed to 'artificial blitzkriegs' and thus rendered immune to fear during air raids.

Bertillon Measurements
You've probably heard of the Bertillon System, one of those discredited "scientific" theories detailing how body measurements indicated racial and/or criminal aspects of a person.Well, here's how the NYC Police Department went about securing Bertillon measurements, circa 1908--courtesy of the George Bain Collection at the Library of Congress.

Decomposition of a Pig
A time-lapse movie of a decomposing pig, taken by Dr. Jerry Payne in the 1960s as part of his graduate studies. It's four days compressed into six minutes. Not much happens at first, but around the 3 minute mark things get pretty interesting. There's a nasty little surprise at the end as well. (Note: the pig died of natural causes.)The purple dots that appear around 2:40 are beads to show the movement of soil by insects.
You may not want to watch this while you're eating a meal.

Cat-Rat Cooperation Disproves Darwin
Chuck's post last week about the guy who trained a rat to sit on top of a cat sitting on a dog, reminded me of the groundbreaking research of Dr. Loh Seng Tsai, conducted back in the late 1940s/early 1950s.Dr. Tsai trained a cat and a rat to cooperate together in order to get food. From the LA Times, July 15, 1951:
The latest research was done with the aid of special apparatus composed of three sections separated by electrically controlled screen gates. First section is the entrance or release box, where a cat and a rat assemble for a test. The second section is the reaction chamber where cooperation takes place.
To get into the third section, where a dish of food awaits, the cat and mouse must each step on a floor button simultaneously. When this is done by perfect cooperation the gate drops and both animals thus gain admittance to the food chamber.
To get into the third section, where a dish of food awaits, the cat and mouse must each step on a floor button simultaneously. When this is done by perfect cooperation the gate drops and both animals thus gain admittance to the food chamber.
Dr. Tsai reported that, "Soon all the pairs of cats and rats began to work together. Finally their cooperation was so perfect that they took only three seconds to reach their food from the entrance."
Dr. Tsai figured that these results disproved Darwin's concept of the Survival of the Fittest. He told the LA Times reporter: "In the face of the fact that even alley cats and rats live together, eat together, sleep together, play together and work together, Darwin's theory seems at most only a half-truth."
What's really amazing is that this guy was a professor of biology at first the University of Chicago, then Tulane, then UCLA, and yet he didn't seem to have a clear understanding of what Darwin meant by the Survival of the Fittest. Nor, as far as I can tell, did anyone ever call him out as a crackpot. In fact, there was talk of nominating him for the Nobel Peace Prize.

Dr. Dove’s Unicorn Bull
In 1933 Dr. W.F. Dove, a biologist at the University of Maine, conducted an experiment to find out if he could create a "unicorn bull." He removed the two knots of tissue on the side of the bull's head that would normally have developed into horns and transplanted them to the center of the forehead. The experiment was a success. A single, massive horn grew there. The unicorn horn made the bull the unchallenged leader of its herd. But Dr. Dove observed that the unicorn bull was actually an extremely docile creature. He wrote:
Although he is an animal with the hereditary potentiality for two horns, he recognizes the power of a single horn which he uses as a prow to pass under fences and barriers in his path, or as a forward thrusting bayonet in his attacks. And, to invert the beatitude, his ability to inherit the earth gives him the virtues of meekness. Consciousness of power makes him docile.

Eating Glass
The new Google magazine archive is a goldmine for weirdness. Here's another find from Popular Science, Nov 1931:EATS GLASS AND STRING TO AID STOMACH STUDY
Glass beads, strands of knotted thread, and even tiny pellets of gold is the diet of Frederick Hoelzel, Chicago, Ill., university student, since he offered to aid physiologists of the University of Chicago in research work on indigestion. The foreign objects are mixed with his meals, and his stomachaches come under laboratory scrutiny. They are no novelty to the subject of this unusual experiment; he volunteered for the tests because he already suffered from severe digestive troubles.

The full results of Hoelzel's glass-eating study were published in the American Journal of Physiology, (Mar 1, 1930), "The Rate of Passage of Inert Materials Through the Digestive Tract." The article includes a helpful chart, detailing exactly how long it took for various substances (including steel ball-bearings and bent silver wire) to pass through Hoelzel's system:
Hoelzel was an interesting character. He became an expert on nutrition and often subjected himself to grueling diet experiments -- particularly experiments involving fasting for extended periods of time. The Life photo archive has a picture of him, taken in 1955. He seems to have been one of the first researchers to make a link between calorie-restriction and longevity, though it didn't really work for him. He died in 1963 at the age of 73.
