Drs. William Johnson and Robert Truax of Louisiana State University raised and studied featherless chickens.
Aside from the physical problems, the chickens have social problems and psychological hangups, Johnson said.
"I guess 'embarrassed' is as good a word for it as any. You put one of them in with a flock of normal birds, and it huddles off in a corner by itself. The other birds won't have anything to do with it until they get used to it," he said.
"And then they're just not as active sexually. They will court and strut much more than the normal bird, but they don't mate as readily."
The story reminds me of the old urban legend about KFC raising mutant, featherless chickens. Maybe this is where the story started.

As a young doctor-in-training at the University of Illinois Medical School in the early 1950s, Lloyd Thomas Koritz volunteered to be a guinea pig in a variety of experiments. In one, he ate a pound of raw liver daily (washed down by a quart of milk) to help study liver metabolism. In a fatigue study he was kept unconscious for 11 hours.
But the most dangerous experiment involved being hung in a harness from a specially-constructed mast and knocked out with anesthesia and curare, so that his breathing stopped. Researchers then tested methods of resuscitating him. They were searching for more efficient ways of resuscitating electrocuted power line workers, so that they could revive the workers while they were still hanging from the poles instead of having to lower them while unconscious to the ground, which takes a lot of time.
I think it would be hard nowadays to get approval to do these kinds of tests on human subjects. Koritz said he disliked the liver-eating experiment the most. In 1953 he was given the Walter Reed Society Award for being willing to repeatedly risk his life for the sake of science.
"Drugged into unconsciousness and paralysis, [Koritz] willingly risked insanity
and death in a significant experiment. This test helped determine the best way
to revive electrically-shocked linemen."

A device for simulating driving, and measuring the skill of drivers, which was developed at Iowa State's Driving Research Laboratory in the 1930s.
A description of what it felt like to operate the thing. It sounds like it would have made a good arcade game. From The Dalles Chronicle - Aug 21, 1936
Dr. Alvan R. Lauer of Iowa State college sent here today a shiny red instrument of torture, designed apparently to give the ordinary, garden-variety motorist the everlasting willies. This device, which Dr. Lauer invented and christened the drivometer, insidiously reverses the usual laws of nature and turns them wrong side forward. The drivometer consists essentially of an automobile which doesn’t move, and a landscape which does, at 50 miles an hour. Imagine that, if you can! We couldn’t either, until the American Automobile association persuaded us to sit behind the wheel. The road twisted like a hula dancer – and we were supposed to steer down it, paying close attention to stop lights, warning signals, WPA men working, and hot dog stands. Never before have we had such a ride. We knocked a truck off the road. We ran down a farmer’s daughter and we wrecked his house. We whanged into a freight train, jumped across a mountain range, drove through a lake and smashed an ice cream shoppe into tutti-frutti. We tried to stop the thing, but everything we pressed made it go faster. We shifted into reverse and raced to the rear, bumping barns, beats and bicycles. Sadly shaking his head, Earl Allgaier, the AAA safety expert, turned off the current. He said we didn’t seem to be very well coordinated, somehow, but that he’d test us on his other machinery. This, together with the drivometer, will be taken on a nationwide tour beginning next week to prove to the average motorist that he’s got a lot to learn.
I think the top picture shows the 2nd version of the Driveometer, developed in the 1950s. The original version, from the 1930s, is below.

A fat mouse that was bred at Jackson Laboratory in Bar Harbor, Maine during the late 1940s/early 1950s. The researchers called him "Obese," or "O.B." for short. As in, that was his name, not just a description of what he was. Fat mice bred from Obese were used in the study of diabetes and obesity.
Newsweek - Apr 2, 1951
Ellen Ruppel Shell tells the story of Obese in her book The Hungry Gene: The Inside Story of the Obesity Industry
In 1947, a wildfire swept through Mount Desert Island and the laboratory, incinerating all but a scattering of the mice. Little
was determined to rebuild, and donations of mice — all of them originally bred at Jackson — poured back to the lab from around the United States, Canada, and Great Britain. Among these was a new mutant, the dystrophic mouse that Coleman
would use as his model for the study of muscular dystrophy. And two years later, another mutant suddenly appeared in the lab — a mouse with traits that would, some twenty years later, attract and hold Coleman's attention for the rest of his career.
An animal caretaker first spotted the creature huddled in a corner of its cage, grooming itself. It was furrier than most, but what really stood out was the size of the thing — it was hugely fat. The caretaker alerted doctoral candidate Margaret Dickie, who diagnosed the mouse as "pregnant." But there were problems with this theory. For one thing, the mouse never delivered a baby. And on closer inspection, it turned out to be male. The fat mouse ate three times the chow eaten by a normal mouse, pawing for hours at the bar of the food dispenser like an embittered gambler banging away at a recalcitrant slot machine. Between feedings it sat inert. It seemed to have been placed on this earth for no other purpose than to grow fat.
There had been other fat mice. The agouti mouse, named for its mottled yellow fur similar to that of the burrowing South American rodent, is, in its "lethal yellow" mutation, double the weight of the ordinary variety. But the fat agouti was svelte compared to the newcomer. This mouse was outlandish, a joke, a blob of fur splayed out on four dainty paws like a blimp on tricycle wheels. Rather than dart around the cage in mousy abandon, it was docile, phlegmatic, as though resigned to some unspeakable fate. Dickie and her colleagues christened the mouse "obese
," later abbreviated to "ob," and pronounced "O.B.," each letter drawn out in its own languid syllable.
Noting that "the role of smells in how we perceive heritage has not been systematically explored until now," researchers at University College London have developed a "Historic Book Odour Wheel."
They tested it on visitors to St Paul's Cathedral's Dean and Chapter library in London, who characterized the smell of the library as 'woody,' 'smoky,' 'earthy,' and 'vanilla.'
The researchers say, "the Historic Book Odour Wheel could potentially be used to recreate smells and aid the design of olfactory experiences in museums, allowing visitors to form a personal connection with exhibits by allowing them to understand what the past smelled like."

Back in the 60s, the U.S. Army employed scientists to sneak into Omaha stockyards and spray cows with deodorant. The logic behind this was to test how easy it would be for Soviet agents to spread hoof-and-mouth disease among American cows.
Unfortunately, I can't find any more info about this operation, which is a shame because it raises so many questions. For instance, the important part of the operation must have been to see how easily they could gain access to the stockyards. So then, why bother to deodorize the cows? Was it just to add a touch of realism? Why not spray them with paint so that they could later count the "infected" ones?

Researchers in Korea are developing a technology that will allow humans to control turtles through thought alone. This is achieved without having to implant any device inside the turtle's brain. Nor does it involve telekinetic powers.
It takes advantage of the fact that a turtle will reliably walk towards a white light, because of their instinctive escape behavior. So the turtle wears a "stimulation device" that blocks its view except in a specific direction that can be remotedly adjusted by a human wearing a "brain-computer interface." The interface can pick up simple thought commands: left, right, or idle. It then transmits the command to the turtle stimulation device, which adjusts its position, and the turtle walks in the desired direction.
The researchers note that their system "could have military applications such as reconnaissance and surveillance," and also "this system could be used in unconventional applications such as immersive virtual reality systems that give the user a sense of oneness with the controlled animal, as if it were their surrogate agent."

Researchers at Nanyang Technological University in Singapore recently made an unusual discovery, which is that "the magnetic properties of living cockroaches are strikingly different from those of dead cockroaches."
Place a living cockroach in a magnetic field and it'll become magnetized, and then stay magnetized for about 50 minutes.
Place a dead cockroach in a magnetic field and it'll also become magnetized, but then remain magnetized for almost 50 hours.
The reason for the difference:
Cockroaches become magnetized because they contain magnetic particles that become aligned with an external magnetic field. These particles are trapped in a runny medium that has low viscosity in living cockroaches. But as soon as the creatures die, the medium begins to harden and its viscosity increases.
So I'm curious how strongly magnetized dead cockroaches become. Would it be possible to use them as refrigerator magnets?

If a pregnant rodent is exposed to the scent of an unfamiliar male, she will often spontaneously abort. This is known as the Bruce Effect
, after researcher Hilda Bruce who discovered the phenomenon while working at London's National Institute for Medical Research (NIMR) in the 1950s.
It's thought that the female rodent does this in order to make herself ready for mating with the new male — because the new male would probably kill the children of the other father once they were born, so why bother carrying them to term. The trick doesn't work with the scent of a castrated male.
The history of the NIMR (pdf - page 208
) offers some interesting details about Bruce's research. The Parkes mentioned was Alan Parkes, her boss:
The Bruce Effect implied that every male mouse smells different to every other male mouse, at least to female mice, and that he produces a spectrum of odours that vary slightly between individuals of the same strain and differ markedly between individuals of different strains. With lateral thinking on how to prove their theory, Bruce and Parkes turned to Boake, a world famous perfumery.
Knowing how skilful perfumers must be in distinguishing between thousands of different odours, they persuaded some Boake representatives to visit NIMR for the purpose of smelling the mice. They invited them to sniff at pieces of cloth that had each been exposed to different cages of various mouse strains. The perfumers had no difficulty in distinguishing the different strains as all had a unique aroma; they even commented that four of the strains were quite similar – all of which had been bred from one original colony at Hampstead. They also noted that the CBA mouse strain, which was fairly new to NIMR, had a wonderful and pleasantly musky smell that could be of commercial interest in perfume manufacture!
Before 2014, science had information about which insect species delivered the most painful sting, but it didn't have info about how the painfulness of stings varied by body location. So Cornell University graduate student Michael Smith set about to correct this omission. He used honey bees to sting himself in 25 body locations and then rated the painfulness of the stings on a 1-10 scale. He published his results in the online journal Peer J
(Apr 3, 2014, "Honey bee sting pain index by body location"
From the article:
Guard bees were collected in a cage, and used immediately. Bees were taken from the cage haphazardly with forceps. To apply the sting, the bee was grabbed by the wings and pressed against the desired sting location. The bee was held against the sting location until the sting was first felt, and kept at the location for 5 s to ensure that the stinger would penetrate the skin. The bee was pulled away after 5 s, leaving the stinger in the skin. The stinger was left in the skin for 1 min, and then removed with forceps.
And the results:
The three least painful locations were the skull, middle toe tip, and upper arm (all scoring a 2.3). The three most painful locations were the nostril, upper lip, and penis shaft (9.0, 8.7, and 7.3, respectively).
In 2015, Smith received an Ig Noble Prize
for his efforts.
