In 1970, biologist Richard Wassersug conducted a study to determine what different kinds of tadpoles taste like. More specifically, whether some taste worse than others. He convinced 11 grad students to be his tadpole tasters.
The standardized tasting procedure included several steps. A tadpole was rinsed in fresh water. The taster placed the tadpole into his or her mouth and held it for 10-20 sec without biting into it. Then the taster bit into the tail, breaking the skin and chewed lightly for 10-20 sec. For the last 10-20 sec the taster bit firmly and fully into the body of the tadpole. The participants were directed not to swallow the tadpoles but to spit them out and to rinse their mouths out at least twice with fresh water before proceeding to the next tadpole.
The most distasteful tadpole was Bufo marinus, while the most palatable ones were Smilisca sordida and Colostethus nubicola.
This confirmed his hypothesis that the most visible tadpoles were the least palatable. Their bad taste deterred predators from eating them, whereas the better tasting tadpoles relied on concealment to avoid being eaten.
1915: Inventor Percy Terry of Los Angeles believed that he had perfected an ointment that would toughen the skin so much that it would become bulletproof. He envisioned "an army of bulletproof men who could advance with immunity against anything less than cannon."
He decided to test the ointment on himself. After rubbing it into his skin for several weeks, he shot himself in the face. Turned out, he wasn't bulletproof. He died at the County Hospital.
In order to advance medical knowledge, Dr. Stephen Sulkes and a handful of volunteers ate Hydrox cookies and later checked to see if their poop had turned black. It had. They named this phenomenon 'Hydrox Fecalis.' Their results were published in the New England Journal of Medicine (Jan 5, 1984). Reproduced below:
To the Editor:
The presence of dark stools can be a cause of consternation to the patient and is made more anxiety-producing when accompanied by abdominal pain or other discomfort. The causes of melena are well outlined in several reviews, along with the usual non-heme causes of black stools, including iron, bismuth, charcoal, licorice, and certain fruits.
To this list should be added the colorings present in chocolate sandwich cookies. In several independent tests (with myself and several volunteers as experimental subjects), the presence of black stools approximately 18 to 24 hours after ingestion of 225 to 450 g of chocolate sandwich cookies has been observed. Variation in brand of cookie did not change the stool character. Testing with other types of cookie (oatmeal, peanut butter, and chocolate chip, among others) has not resulted in the same stool findings, although abdominal pain or nausea or both appear to be equally frequent associations.
This phenomenon may be on the increase because of shifts in U.S. dietary habits, so elicitation of a good dietary history in cases of black stools and abdominal pain should be pursued. Inasmuch as "cookie-induced pseudomelena" is both unprofessional sounding and too appropriately descriptive, a suggested name for this entity is "Hydrox fecalis."

Someone needs to repeat the experiment with Oreo cookies.
I realize that the indentations on top of bricks are called 'frogs', but why were actual frogs being placed inside bricks?
As far as I can tell, it must have been an experimental demonstration of the 'pressed frog phenomenon' — this phenomenon being that one can place a living frog inside a brick as its being made, apply thousands of pounds of pressure to the brick to mold it, and the frog will survive. The frog won't be happy about the experience, but it won't burst. Whereas the same pressure applied to a frog that isn't in a brick will definitely cause it to burst.
Obviously the brick hasn't been heated in a kiln, because that would definitely cook the frog.
The article below from 1925 explains the science of why a frog in a brick doesn't burst. The key part of the (overly long) explanation is this sentence:
when the pressure was exerted gradually there was a tendency for the particles of clay around the body to "wall up" the body by the grains of clay moving instead of a tendency of the body "bursting" by the particles of the body moving.
However, this doesn't solve the mystery of who first decided to put a frog in a brick.
The non-fiction book Shadows in the Sun by Wade Davis contains the following passage:
There is a well known account of an old Inuit man who refused to move into a settlement. Over the objections of his family, he made plans to stay on the ice. To stop him, they took away all of his tools. So in the midst of a winter gale, he stepped out of their igloo, defecated, and honed the feces into a frozen blade, which he sharpened with a spray of saliva. With the knife he killed a dog. Using its rib cage as a sled and its hide to harness another dog, he disappeared into the darkness.
In 1954, six young boys who exhibited violent behavior were brought to live on the grounds of the National Institute of Health in Bethesda, Maryland. They were specifically selected because they were deemed the worst of the worst:
The boys were selected on the basis of the consistent ferocity of their behavior, as documented in the records of courts, schools, and social agencies. Though they were only eight to ten years old at the time they became charges of the government, their case histories were long and strikingly similar: classroom difficulties ranging from inability to learn to violent tantrums, truancy, stealing, fire-setting, assaults—often fiendish in their ingenuity—on other children, sexual misbehavior, and so on.
For the next five years, the boys were attended around the clock by a team of specialists.
It was all part of an experiment, which came to be known as the "Case of the Furious Children," designed to find out why these young boys were so violent and whether they could be turned into responsible citizens. Eventually, around $1.5 million (in 1950's dollars) was spent on this effort.
By the end of the experiment, one of the researchers, Dr. Nicholas Long, said that the boys now had a "better than 50-50 chance of living a productive life." So what became of them? Were they reformed, or did they head down the path of crime and prison that they originally seemed to be destined for?
I'd be interesting to know, but I haven't been able to find anything out. I'm guessing the info has never been released because of privacy issues.
Scientists at Israel's Ben-Gurion University of the Negev trained goldfish to drive a "fish-operated vehicle" or FOV. Details from scmp.com:
Each fish was put into the FOV – equipped with a fish tank – at different locations in a room and tasked with a goal to drive to a visual target. If they steered to the target, they were rewarded with a fish pellet. To the scientists’ amazement, the goldfish successfully reached the target after a few days of training, no matter what position they started in or if they were interrupted by hitting a wall or by false targets, according to the release.
Research by biologists Noam Sobel and Idan Frumin reveals that after a handshake people frequently lift their hand to their nose and sniff it. The researchers hypothesize that this is to smell the body odor of the other person.
Sobel also conducted a fascinating experiment with his graduate student Idan Frumin to see what people did with their hands after a handshake. Their team secretly videotaped people after they shook the hand of someone new, someone they had just met for the first time. Here's their delicious discovery: A few seconds after the handshake, the experimental subjects would inevitably sniff their own hands, to gain some odorous information about the new person.
"When we showed them the videos, many of the subjects were completely shocked and disbelieving," Frumin told me. "Some thought we had doctored the videos - not that we had the computing power or the expertise to do so."
. . . When Frumin now goes to conferences, he sometimes stands back and watches people unconsciously sniffing. "Sometimes I catch myself doing it too. People tell me I've ruined handshakes for them, that they've become very self-conscious about shaking hands, especially with me."
Controversial experiments in which British government scientists subjected newborn lambs to prolonged periods in a wind tunnel and baths of cold water to test their weather resistance have been stopped by the Agricultural Research Council.
After spending more than $40,000 on the experiments the scientists concluded that lambs with short wool got cold faster than lambs with long wool.
In 1974, Dr. Adrian Upton of McMaster University placed E.E.G. electrodes on a blob of lime jello and obtained positive readings. This indicated brain activity. He published his results in 1976 in the Medical Tribune.
Upton was trying to demonstrate that when doctors use an E.E.G. to determine brain death, it can be difficult to obtain a perfectly flat readout, because the equipment picks up stray electrical activity from the surrounding environment. Or maybe he had discovered that jello is a sentient lifeform.
The Jell-O Gallery Museum in Le Roy, New York seems to prefer the latter conclusion. A brain-shaped jello mold on display at the museum bears the message: "A Bowl of Jell-O Gelatin and the Human Brain Have the Same Frequency of Brain Waves."
