We like aggressive music – Strong, sad, full of emotions
We like aggressive music – Strong, sad, full of emotions – We are more willing to choose sad, troubling and full of anger songs. This phenomenon was observed by analysts from Lawrence Technological University. They used an automated system to evaluate the lyrics of the most popular songs listed on the Billboard Hot 100 list from the end of the 1950s until the end of 2016. In total, about 6,000 works were examined. The algorithm assigned each emotional value, and then the average for the whole year.
As Kathleen Napier and Lior Shamir, who analyzed this data, observed, the most optimistic, joyful songs are the oldest ones. From that time on, anger, fear and sadness began to take over to reach the apogee in 2015. Only the middle of the 1970s and the beginning of the 1980s breaks from this trend.
As the researchers emphasize, it does not mean that the music itself has changed
Increasing aggression in the text layer does not mean growing aggression of the creators. This is a sign that the tastes of music consumers have changed
– says Lior Shamir. –
We just want to listen such things.
Growth psychology – laughter isn’t acquired but innate
Growth psychology – laughter isn’t acquired but innate – British scientists have proved
that laughter is not something acquired, but innate. With the help of ultrasound was recorded
children in the uteri. The first facial movements have been observed in the second trimester,
and all elements detecting a laugh approx. 30 weeks. It was thus negated one of the existing
theory of psychological development.
Human body bacteria – Weight of digestive tract microorganisms
Human body bacteria – Weight of digestive tract microorganisms – The total weight of bacteria
living in the human digestive system is approx. 1.5 kg. In the large intestine,
we have 100 trillion microorganisms. 10 times more than the number of all cells in the body.
They are divided into roughly 400 species.
Studies have shown that it is the changes in the number and species of bacteria in the gut
have a negative impact on the psyche of the patients. According to specialists bacterial flora
may be responsible not only prone to depression, but depression symptoms in themselves.
At one cm square elbow stays on average 10 thousand. bacteria – 113 different species,
but more than 90% are 10 of them. The least bacteria on human skin found between the toes,
the largest habitat of the navel.
Alcoholism effects – Repairing damaged neurons
Alcoholism effects – repairing damaged neurons – Scientists from Wurzburg in Germany
found that damage to brain cells caused by excessive alcohol consumption can be repaired only partially.
They note that in the interest of alcoholics is the fastest return to sobriety. Longer heavy drinking
causes brain regeneration proceeds with great difficulty.
Impact hair thinking – Hair arranged in the left side
Impact hair thinking – Hair arranged in the left side – Researchers from the University of Bonn
have discovered that only a small part of the population. Hair around the crown arranged to the left.
They proved that the hair arranged in the left side may have a similar effect on the functioning of the brain
as writing with left hand. Thus confirming the theory that describes the stacking of hair left
almost exclusively left-handed persons.
Aggressive blonde – Psychologist at the University of California, Dr Aaron Sell.

Threat associated with stress
Threat associated with stress – Stress arising through work or school, can lead to serious health problems. Such as cardiovascular diseases or the development of depression. Engineers from the lab ETH Zurich have developed in connection with this small device that allows you to measure stress levels. The instrument combines the measurement of skin conductance, heart rate and breathing with the measurement of stress hormones in saliva.
Spouses similarity – Assortative mating
Spouses similarity – Assortative mating – Evolutionary biologists and psychologists have called this phenomenon assortative mating.
“The choice of the man who is to us in a similar way, makes sense from an evolutionary point of view. Namely the physical resemblance is key to genetic similarity. This increases the likelihood that our genes are reliably transferred to the next generation “
– explains prof. Philippe Rushton, a psychologist at the University of Western Ontario – his work has shown that we choose mainly those features that have a higher heritability. To which include, for example, an increase in the circumference of the wrist, but not waist circumference.
Through stomach to brain
Through stomach to brain – Researchers University of California at Los Angeles found that in people who do not consume dairy products part of the brain associated with processing emotions and feeling of the body is more stable or increased.
