Scientists Who Experimented On Themselves

Posted by Jill Harness in Health, History, Living, Science & Tech, Society & Culture on December 28, 2011 at 1:38 pm

Science is a field based largely on theory and experimentation, which is why you have to be pretty darn certain you are right if you’re willing to test your ideas on yourself. For example, in the picture above:

In 1929 in the basement of the Eberswaled Hospital in Germany, surgical resident Werner Forssmann inserted a ureteral catheter tube into his elbow, feeding it through a vein up to his heart. He used a mirror as his assistant, since he had restrained his nurse to the operating table. He then took an x-ray of his chest (at left) to determine the catheter had indeed made it to the right atrium.

Why Do Some People Learn Faster?

Posted by Miss Cellania in Science & Tech on October 5, 2011 at 6:04 am

An article at Wired covers several experiments in brain function and learning. First, we find that there are two distinct reactions in the brain when we make a mistake, and their relative performance determines how well we learn from a mistake. Then we find that people with open minds are more likely to change their behavior after a mistake. And then there’s a real world application, tested by Stanford psychologist Carol Dweck.

Her most famous study, conducted in twelve different New York City schools along with Claudia Mueller, involved giving more than 400 fifth graders a relatively easy test consisting of nonverbal puzzles. After the children finished the test, the researchers told the students their score, and provided them with a single line of praise. Half of the kids were praised for their intelligence. “You must be smart at this,” the researcher said. The other students were praised for their effort: “You must have worked really hard.”

The students were then allowed to choose between two different subsequent tests. The first choice was described as a more difficult set of puzzles, but the kids were told that they’d learn a lot from attempting it. The other option was an easy test, similar to the test they’d just taken.

When Dweck was designing the experiment, she expected the different forms of praise to have a rather modest effect. After all, it was just one sentence. But it soon became clear that the type of compliment given to the fifth graders dramatically affected their choice of tests. When kids were praised for their effort, nearly 90 percent chose the harder set of puzzles. However, when kids were praised for their intelligence, most of them went for the easier test. What explains this difference? According to Dweck, praising kids for intelligence encourages them to “look” smart, which means that they shouldn’t risk making a mistake.

A further experiment showed how fear of failure can inhibit learning. Read about all of them at The Frontal Cortex. Link

5 Science Experiments Gone Wrong


Every day, scientists are striving to make our lives better and to better understand our lives through a range of experiments on just about every subject. Unfortunately, not all of these projects work out so well. These five experiments have all gone wrong, whether due to the errors of the scientists, the unexpected behavior of the subjects or because the public reaction destroyed what may have actually been an advantageous advance in the field.

Tripping Elephants On Parade

While many test animals are killed in the name of research, many of them are at least being used to investigate potentially life-saving drugs. Perhaps the saddest and most spectacular failure of any animal-based experiment occurred in 1962, when Tusko the elephant (not the one pictured) was given LSD simply for the sake of seeing how the magnificent beast would react to such a substance.

Unfortunately, the researchers, Louis Jolyon West and Chester M. Pierce, had no idea how much LSD it would take to dose an elephant. Rather than erroring on the side of safety, the doctors decided that they didn’t want to have to do the experiment again just because they underdosed the elephant the first time. They ended up deciding to give Tusko 297 milligrams, which is about 3000 times the dosage a human takes, despite the fact that an elephant weighs about 90 times more than the average human.

After being dosed, Tusko immediately started running around in his pen and soon lost control of his movements, eventually collapsing to the ground and going into seizures. To counteract the LSD, the doctors gave the elephant 2,800 milligrams of an antipsychotic. The drug reduced his seizures slightly, but didn’t stop them. After another hours, the doctors decided to give Tusko a barbiturate to calm him down, but it didn’t help. He died a few minutes later.

Two other elephants were later dosed with the drug and suffered no ill effects. Ultimately, the doctors that dosed Tusko summed up their experiment in Science by saying, simply, “It appears that the elephant is highly sensitive to the effects of LSD.” Even so, it is still unclear whether or not Tusko died from the acid or a combination of the three drugs given to him that day.

The Monster Study

The effects of positive vs. negative reinforcement have fascinated scientists and parents for hundreds of years. Unfortunately, testing on a group of unsuspecting orphans isn’t the best way to find out. In 1939, Doctor Wendell Johnson of the University of Iowa and his assistant, Mary Tudor, selected 22 children from an orphanage in Iowa. Ten of the children had stutters and the rest spoke just fine.

The stutterers were put in two groups, group IA that was to use positive reinforcement and other, group IB, that was to receive negative reinforcement. The non-stutterers were also broken into two groups, group IIB, that was told they spoke fine, and group IIA, who were told they were starting to stutter and needed to avoid making mistakes at any cost. The goal was to get those in group IA to stop stuttering and those in group IIA to start stuttering.

The impact on group IIA was exactly what the doctor had hoped for. The entire group started falling behind on their school work. The children started to second-guess their speech abilities and many stopped talking at all. One girl ran away shortly after the experiment ended. While Mary Tudor visited the orphanage three times after the experiment was over, attempting to convince the children that they didn’t have any speech problems, the damage was already done. Although none of the kids became stutterers, many of the children retained speech problems their entire life and most were reluctant to speak. In 2007, six of these children were awarded $925,000 in a lawsuit against the state for the university’s role in the experiment.

The study has since been dubbed “The Monster Study” by the public and scientists alike who were disgusted with the doctor’s methods.

Silly Experiments in Spaaaace!

Koichi Wakata, a Japanese Astronaut who is working aboard the International Space Station was given the task to perform a few silly experiments in Zero-G requested by the Earth People of Japan. They consist of the mundane such as performing push-ups, squirting water from a tube, backflips and so forth but then some of them are bizarre like the “flying magic carpet” request! Oh, how I wish I were in space like Koichi and the other fine men and women of the ISS crew! I would see to it if I could perform the moonwalk in Zero-G! ;)

10 Real Life Mad Scientists

Posted by Queuebot in Science & Tech on March 31, 2009 at 8:23 am

Throughout history there have been a few lost souls who have taken the beauty of science and instead of honoring it, twisted it and contorted it into something evil.  

Science, we are informed by conscientious historians of the discipline, is something that comes to us without anything we might call a “moral imperative” as to what we should or should not be doing with the knowledge. In fact, science has often been described as an “amoral” enterprise, which can be put to evil uses just as easily as good ones. Scientists themselves bear no responsibility to ensure how their discoveries are used by others.

But what if the scientist himself is a diabolical mad man?

They Paid You For That? 7 Pointless and Crazy Science Experiments

Posted by Jill Harness in Neatorama Exclusives, Science & Tech on March 2, 2009 at 3:56 am

Have you every read about some new science experiment or research study that just seems… well, stupid? If you’ve ever gotten to the point where you’ve wondered what other bogus things they’ll pay people to learn about, you’re in luck. Here’s 7 of the most ridiculous studies ever:

Sex, Drugs and Science

If this first group of studies show us anything, it’s that scientists are as drugged up and crazy as the junkies up the street from me.

Elephants on Acid:

If you were going to see the effects of LSD on an elephant, wouldn’t you start with smaller doses and progressively increase the dosage until there was a noticeable change in their behavior? I sure would. But the researchers on this one aren’t like you and me.

Instead the researchers working on this one started off by injecting the poor beast with 3000 times the dosage needed for an average human, despite the fact that elephants weigh around 50 times what the average human weighs. Within two hours, the animal died. The scientists defended their actions by saying they had used LSD plenty of times and were sure it was safe. They then concluded, “elephants are highly sensitive to LSD.”

Apparently another scientist found their results to be suspicious, so he gave elephants LSD in their water. In his study, the elephants acted a little funny, but were totally fine.

Turkey Arousal:

We’ve all heard stories detailing how stupid turkeys are -like the one that says they’ll drown if you leave them in the rain. Well, some of those turkey stories may be bogus, but two Penn State researchers discovered that turkeys are so stupid they can be trained to be aroused by little more than sticks.

Their experiment consisted of creating a model female turkey that could be progressively deconstructed. The scientists would then gauge the turkey’s interest in the “female” and then remove some parts of her body and try again. They were expecting the birds would lose interest after is was stripped down enough. Surprisingly, the turkeys were aroused even when the model became little more than a stick with a head. I guess this not only shows how stupid turkeys are, but how perverse they are too.

Semen As an Anti-depressant?

I always thought scientists were supposed to be unbiased. I mean, if you’re hoping for certain results, might that affect your research? Obviously these researchers bypassed that concept, by attempting to prove that semen works as an antidepressant. They decided to study this theory by interviewing college women who were sexually active. Their conclusions proved that women who had sex without condoms were less depressed than women who used them.

Of course, their research was extremely preliminary and they didn’t even bother to take into account additional factors, like the fact that women not using condoms are more likely to be in serious

relationships. It doesn’t take a scientist to figure out that this might play into someone’s relative level of happiness. But like I said, this study was about as unbiased as all those tobacco company ones that couldn’t connect smoking with cancer.

Paging Dr. Obvious

The rest of these studies are amazing -in that someone actually bothered to research things so obvious:

Head Banging is Bad For You:

Who would have ever thought that aggressively and repeatedly throwing your head up and down would be bad for you? Gee, I never would have imagined that spinal damage and brain trauma could have resulted from head banging. Obviously, I’m being sarcastic. After years of dating a metal head, I can assure you that head banging can certainly make you retarded…or at least, it doesn’t help your intelligence at all.

The only good thing researchers found was that head banging is unlikely to leave you unconscious. What is really funny is the researcher’s suggestions for the metal genre. They suggest metal bands play more

mellow tunes and less “beat oriented” music. They also urged label to place anti-head banging warnings on their cds. Oh, and listeners were advised to start listening to “adult-oriented rock” instead of heavy metal. Yeah, that’s gonna happen real soon.

Male science nerds likely to be virgins:

Hmmm, who is most likely to be a virgin, a party-girl, a jock, or a nerd? Think about it. No surprise here; male science nerds between 16 and 25 are the most likely to not have had sex.

At least the study provided some legitimate reasons for this statistic, rather than the typical “nerds are pimply and boring” theories of popular media. The study reasoned that these nerds were the population segment least likely to be in situations where they would meet potential lovers. Apparently, doing homework and going to the library doesn’t help you meet chicks. Hey, at least they’re being productive. Interestingly, female art students were the most sexually active.

Bullies Like Seeing Pain:

If bullies were compassionate they would sit around crying whenever they picked on people. The fact that they don’t do so might just indicate that they are mean. Why did anyone need to set up a study to confirm that bullies enjoy seeing other people in pain?

An interesting thing about this study is that it was the first time anyone used fMRI to evaluate how respondents reacted to different emotions. Instead of being empathetic like the brain of a normal person, bullies mind’s activate their reward centers when they see videos of other people being picked on.

Television Viewers Are Unhappy:

It’s common knowledge that television and other forms of entertainment are a way for people to escape their problems. If you run home to watch tv instead rather than hanging out with friends, you might be unhappy. Did we really need a scientist to tell us that people who socialize are generally more happy than people who sit at home watching tv all day? What’s more crazy is that they needed over 30 years of data to back up their claims. The only unique thing the study discovered was that many viewers are actually addicted. (Marx was right about television, is this evidence that the scientists are commies?):

“Addictive activities produce momentary pleasure and long-term misery and regret,” said Steven Martin, co-author of the study. “People most vulnerable to addiction tend to be socially or personally disadvantaged. For this kind of person, TV can become a kind of opiate in a way. It’s habitual, and tuning in can be an easy way of tuning out.”

Funny, I’ve was using the audio/visual equivalent of heroin the whole time I was researching this. I swear I could quit any time.

Now that I’ve written this, I think I’ve got a couple of ideas I could get funded. For example, are people happier when they’re warm at home or cold in the middle of nowhere? Or maybe I could find out if donkeys really die when they take a bunch of cocaine and other drugs at a bachelor party. Do you guys have any ideas for awesome studies?
