Thanks to state-of-the-art technology, researchers can become creative with their goals. Bizarre in the name of science will inevitably produce something out of the ordinary. From octopus-covered octopuses and people who read each other's thoughts to a reality that is only contemplated, scientists are breaking new ground.
As with all experiments, not everything was healthy. Some results showed disquieting human-robot relationships and worse – the tendency to torture a helpless victim even existed among those who thought themselves incapable.
10 Goats like happy people
Goats are known for their intelligence. In 2018, an experiment with 20 animals showed another cognitive ability. They can differentiate the facial expressions of people. The brave creatures were trained to walk to the other side of the pen where they received snacks.
In the second phase, two pictures were attached to the back. The photos contained men and women the goats had never met in real life. One picture always contained a smiling person and the other a grumpy frown. The animals were shown only male or female faces, and the images were moved around on the left and right sides of the enclosure.
Gender seemed to make no difference to the goats, who would rather sniff the happy faces. Strangely enough, they chose only the positive images on the right side of the pen. 
This suggests that the left hemisphere of a goat brain deals with friendly clues. It remains unclear how goats understand the face communication of another species, but this test provided the first evidence that they are capable of doing so.
9 The four-day week
Many employees worry about their work environment, especially when companies are making profits for workers. In 2018, a New Zealand company made a radical change. The trust company Perpetual Guardian paid their staff for two full months for four days.
The unique experiment aimed to see if the reduction in business hours had a positive or negative impact on the business. Most entrepreneurs found this risky, but the results were incredible.
The stress of the employees dropped from 45 to 38 percent. Even healthier her work-life balance increased from 54 to 78 percent. The most notable finding was that productivity showed a slight improvement despite the shorter weeks. In addition, the engagement and the positive relationships between employees increased. The leadership improved, and people really enjoyed what they did.
The experiment created something that is rarely seen today – a team loyal to a company that cares about them. Perpetual Guardian now wants to make the four-day week permanent. 
8 Octopuses On Ecstasy
A bizarre-sounding experiment took place in 2018. The researchers collected two Kraken, two Star Wars action figures and some Ecstasy (also called MDMA). It is known that this drug floods human brains with serotonin and turns it into social cuddly bears.
Octopuses are grumpy loners. When they were sober, they avoided their own kind and the toys in their tanks. If they were high on ecstasy, they behaved like humans and became dome with their krake comrades as well as Chewbacca and a stormtrooper.
The loving tentacles unveiled something unexpected. The brain of an octopus and that of a human do not even have the same regions. The two vertebrate and invertebrate groups were separated more than 500 million years ago. But surprisingly, a single gene in the genomes of man and the eight Tentacled miracles agreed perfectly.

SLC6A4 is the genetic binding site of ecstasy, which is why both species are likely to be rosy, loving outlook on life, once stunned with MDMA. No one really expected the socially connected genetic and neurological pathways of humans to exist in other living things.
7 Rogue Kidneys
These days scientists are building organoids – miniature versions of real human organs. In 2018, a mini-kidney stem cell sprouted from a lab. After four weeks nurturing growth in a chemical soup, they were done.
This soup was developed to encourage stem cells to grow only specialized kidney cells. Once the organoids were fully grown, researchers got a glimpse of what was going on in them. Then the surprise.
For some reason, the tiny kidneys were inappropriate and produced brain and muscle cells. These cellular siblings accounted for up to 20 percent of the organoids.
As interesting as the Frankenstein organs are, it was a setback. Organoids are valuable tools for disease research, but if they do not model a real human kidney, all information is likely to be distorted.
Another unexpected discovery was that the laboratory-bred kidneys refused to ripen no matter how they were farmed. This was also problematic for disease studies because prolonged exposure to the soup caused more villainous cells. 
6 . Children believe misleading robots
as a visual inspection. In 2018, the researchers have set their own spin. Around 43 children aged seven to nine years had to find two equally long lines on a screen. The answer was obvious. When the children were alone, they were 87 percent correct. 
Then came the robots. Whenever the child was asked to pick lines, a robot would give the wrong answer. Although the correct answer was simple, the children doubted themselves and looked for the machines. They did this so often that the success rate fell to 75 percent. They simply followed the instructions of the robots, sometimes word for word.
When 60 adults were tested in the same way, they ignored the robots. The children probably experienced an "automation error", a strong belief that machines have greater capabilities than they actually do. Researchers suggest that the adults, who are not affected by the robot robots, may have folded if they were bigger and more imposing.
5 The Tokyo Explosion
For decades scientists have been trying to create larger magnetic fields. Huge ones were created, but their strength was too much for interior design. Outside measurement fields, however, fail in the accuracy department.
In 2018, physicists in Tokyo built an armored room containing the strongest controlled magnetic field produced under laboratory conditions. Such fields are divided into Tesla. The strongest MRI device produced three Tesla's and the Tokyo team aimed for 700. 
Instead, their electromagnetic device broke out with 1,200 Tesla's. This unexpected development made it the strongest controlled field, although "controlled" meant only being able to measure its performance. The actual event destroyed the armored doors of the lab immediately after crumpling the iron box in which it was stored.
Despite the horrors and damaged possessions the team received, the 1,200 Tesla's was a step toward unlimited, clean energy. Nuclear fusion reactors only need a 1,000 Tesla magnetic field to change the world's energy crisis. Scientists now have a strong field. All you have to do is determine how they can stop the explosions.
4 Measurement creates reality
In 1978, physicists suggested that reality be measured only when measured. It sounded funny then, but in 2015, the technology came to prove it. Australian scientists developed a famous 1970s theoretical experiment and showed that the quantum world enveloped this strange law.
The experiment took a single helium atom and sent it through laser barriers (the measurement points) to see if it acts like a restrained wave or particle. Logic dictates that it would be inherent in its nature and that the measurement could not behave differently. [19459011
However, the tests have shown that the atom, bizarre as it may sound, can not do this, deciding whether it should be a wave or a particle until it hits the lasers. To begin its journey, the helium atom was sent through two bundles of rays that were to scatter its way.
Later during his travels, random lasers were added to rejoin the paths. This second measurement somehow expressed the preference of the atom for wave or particle-like behavior.
3 The Murdered Robot
Once upon a time (2015), a robot called hitchBOT. He had an ambition: to travel as far as he could by making trips with strangers. The friendly machine enjoyed the charity of the drivers for two weeks and put back the longest trip of its kind.
After traveling over 10,000 kilometers in Canada and enjoying the prospect of several cities in Germany, hitchBOT wanted to see the whole United States of America. If the electronic wanderer had had parents, they would have warned him against the dangers of tramping.
The designers of hitchBOT developed it as an experiment to see how far human kindness would bring him and how people would interact with a robot without supervision. At the beginning of his great American adventure, he left for San Francisco – and disappeared. [19459011
His beheaded corpse was found in Philadelphia. It had been thrown in a ditch. Worse, his killer had been having fun. The person had also removed HitchBOT's arms and placed them around the body of the robot.
In 2018, neuroscientists were able to connect the brains of three people. You could play a Tetris-like game just by exchanging thoughts. This "network" was called BrainNet.
The participants did not really read the thoughts of others. However, they were able to communicate thanks to the electroencephalograms (EEG) and the transcranial magnetic stimulation (TMS). Two participants were the "senders" and wore EEG electrodes. A third person had a TMS cap and was the "recipient."
The senders played each other, but only the third person could move the blocks. When a player wanted to turn a block, he stared at one of the two LEDs on the screen. The flashing lights triggered signals in the brain that were picked up by the EEG and relayed to the TMS cap. The latter's magnetic field produced phantom flashes in the head of the receiver – a sign to turn the block.
With a success rate of just over 80 percent, scientists hope one day to create a social network of interconnected brain, possibly via the Internet. 
1 The Milgram Experiment
Stanley Milgram discovered a troubling corner of the human mind. In the 1960s, this social psychologist tested how far people would go if they were ordered by an authority person to electrocute another person. Most participants obeyed. The Milgram experiment marked a turning point in obedience and social psychology research.
In 2017, researchers wanted to find out if people today reject empathy for authoritative approval. Most would not feel able to respond to such an influence.
A recently published Polish study recruited 80 people for a "memory attempt". Their task was to shock students who could not remember associations. The shocks were never real. The participants did not know that the "learners" were actors.
About 10 levers led to ever higher voltage surges. Participants were encouraged to zap apprentices who could not memorize, and one authority person encouraged those who became hesitant as the shocks became stronger (and they heard screams). Although participants used three times less severe shocks among female learners, it was a troubling 90 percent.
